TECHNICAL FIELD
The present disclosure relates generally to the field of strap ties, and more specifically to apparatuses, systems, and methods relating to strap ties.
BACKGROUND
Wounds, such as cuts and lacerations in skin and flesh, are often difficult to close in order to properly treat and heal the wound. Bandages may be used to cover a wound. Wounds may be approximated (i.e., edges of wounds drawn together) using sutures, staples, clips, or topical adhesives. Over time, a wound and/or tissue associated with the wound may retract, reopen, or otherwise lose structural integrity. In some cases, clinical/surgical facilities are not readily accessible for treating a wound.

DETAILED DESCRIPTION
The following detailed description and the appended drawings describe and illustrate various strap tie systems, methods, and components. The description and drawings are provided to enable one of skill in the art to make and use one or more strap tie systems and/or components, and/or practice one or more methods. They are not intended to limit the scope of the claims in any manner.
The use of “e.g.” “etc.,” “for instance,” “in example,” and “or” and grammatically related terms indicates non-exclusive alternatives without limitation, unless otherwise noted. The use of “optionally” and grammatically related terms means that the subsequently described element, event, feature, or circumstance may or may not be present/occur, and that the description includes instances where said element, event, feature, or circumstance occurs and instances where it does not. The use of “attached” and “coupled” and grammatically related terms refers to the fixed, releasable, or integrated association of two or more elements and/or devices with or without one or more other elements in between. Thus, the term “attached” or “coupled” and grammatically related terms include releasably attaching or fixedly attaching two or more elements and/or devices in the presence or absence of one or more other elements in between. As used herein, the terms “proximal” and “distal” are used to describe opposing axial ends of the particular elements or features being described in relation to anatomical placement.
In existing solutions to treat wounds, uneven forces applied across the wound limit the efficacy of wound healing, such as by causing scars to form. The present solution provides systems, methods, and apparatuses for applying an even amount of force across a wound in order to more effectively heal the wound and limit scar formation. The present solution includes a strap tie assembly including a first strap tie and a second strap tie. The first strap tie includes a first base configured to be disposed adjacent to a first portion of skin, a first body including a first opening and a first engagement member disposed within the first opening, and a first strap extending from the first body. The first strap includes a first proximal end attached to the first body, a first distal end opposite the first proximal end, and a plurality of first movement restriction members disposed along a surface of the first strap. The second strap tie includes a second base configured to be disposed adjacent to a second portion of skin, a second body including a second opening and a second engagement member disposed within the second opening, and a second strap extending from the second body. The second strap includes a second proximal end attached to the second body, a second distal end opposite the second proximal end, and a plurality of second movement restriction members disposed along a surface of the second strap. The first opening is configured to receive the second strap, and the first engagement member is configured to engage one of the plurality of first movement restriction members of the first strap to prevent translation of the first strap away from the second body. The second opening is configured to receive the first strap, and the second engagement member is configured to engage one of the plurality of first movement restriction members of the first strap to prevent translation of the first strap away from the second body. In this way, the tie strap assembly can provide an even amount of force across a wound. The strap tie assembly may include features such as handles, grips, friction elements, etc., which facilitate manipulation of the strap tie assembly in environments where blood, oil (e.g., lipids), or other fluids could impair manipulation. While the present disclosure illustrates use of the strap tie assembly in the context of wound closure, in various embodiments, strap tie assemblies and components thereof may be used in various applications, including but not limited to general use for securing a surface or multiple surfaces; for drawing or pulling surfaces together; for securing homogenous or heterogeneous surfaces; for applying tension to a surface or multiple surfaces; etc.
Referring to FIG. 1, a perspective view of an embodiment of a strap tie assembly 100 is shown. The strap tie assembly 100 includes a first strap tie 110 and a second strap tie 210. The first strap tie 110 includes a first body 112, a first base 114, and a first strap 116. The first base 114 is configured to be disposed adjacent to a first portion of skin. Similarly, the second strap tie 210 includes a second body 212, a second base 214 configured to be disposed adjacent to a first portion of skin, and a second strap 216. In some embodiments, the second strap tie 210 can be identical to the first strap tie 110. In some embodiments, the first strap tie 110 and the second strap tie 210 are generally similar or identical, and configured to interact in a complementary fashion or an opposing fashion. Stated in another way, the components of the first strap tie 110 and the second strap tie 210 can be disposed or configured to engage each other in an identical manner and/or in a mirror image manner.
In some embodiments, the first body 112 includes a pair of first openings 118, 120. The first body 112 includes a pair of first engagement members 122, 124. The first engagement member 122 is disposed within the first opening 118 and the first engagement member 124 is disposed within the first opening 120. Similarly, the second body 212 includes a pair of second openings 218, 220. The second body 212 includes a pair of second engagement members 222, 224. The second engagement member 222 is disposed within the second opening 218 and the second engagement member 224 is disposed within the second opening 220. While the figures illustrate bodies such as first body 112 and second body 212 as including a pair of openings and a pair of engagement members, in various embodiments, various numbers of openings and engagement members may be used (e.g. 1 opening, more than 2 openings, 1 engagement member, more than 2 engagement members, etc.).
In some embodiments, an opening, such as first openings 118, 120 or second openings 218, 220, is disposed such that a path passing through the opening is generally parallel to a longitudinal axis defined by a strap, such as the first strap 116 or the second strap 216. In some embodiments, an opening, such as first openings 118, 120 or second openings 218, 220, is disposed such that a face of the opening is perpendicular to the longitudinal axis defined by the strap. For the sake of clarity, the two openings will be referred to as upper and lower openings (e.g. first lower opening 118, first upper opening 120, second lower opening 218, second upper opening 220), based on the frame of reference shown in FIG. 1, though the strap tie assembly 100 may be configured to be disposed in various orientations based on various frames of reference. For example, as shown in FIG. 1, the first lower opening 118 is disposed or otherwise defined within a first portion of the first body 112 proximate to the first base 114. Similarly, the second lower opening 218 is disposed within a second portion of the second body 212 proximate to the second base 214. The first upper opening 120 is disposed or otherwise defined within a second portion of the first body 112 farther away from the first base 114 relative to the first lower opening 118. Similarly, the second upper opening 220 is disposed or otherwise defined within a second portion of the second body 212 farther away from the second base 214 relative to the second lower opening 218. In some embodiments, the first strap 116 extends from a third portion of the first body 112 that is positioned between the first portion and the second portion of the first body 112. Similarly, in some embodiments, the second strap 216 extends from a third portion of the second body 212 that is positioned between the first portion and the second portion of the second body 212. In some embodiments, the third portion of the second body 212 separates the first portion of the second body 212 from the second portion of the second body 212.
In some embodiments, the plurality of movement restriction members (e.g., movement restriction members 126, movement restriction members 226, etc.) includes a plurality of ridges. The ridges may define a plurality of grooves (e.g., recesses, cavities, etc.). In some embodiments, the plurality of movement restriction members (e.g., movement restriction members 126, movement restriction members 226, etc.) includes a plurality of holes; a corresponding engagement member (e.g., engagement member 122, etc.) may include a hook or other structure configured to engage a hole.
Referring back to FIG. 1, the first strap 116 extends from the first body 112. The first strap 116 includes a first proximal end 128 attached to the first body 112 and a first distal end 130 opposite the first proximal end 128. The first strap 116 includes a plurality of first movement restriction members 126 disposed along a surface 132 of the first strap 116. Similarly, the second strap tie 210 includes a second strap 216 extending from the second body 212. The second strap 216 includes a second proximal end 228 attached to the second body 212 and a second distal end 230 opposite the second proximal end 228. The second strap 216 includes a plurality of second movement restriction members 226 disposed along a surface 232 of the second strap 216. Additional details pertaining to the interactions between the first engagement member and the first movement restriction members and the second engagement member and the second movement restriction members are provided below.
Each of the pair of first openings 118, 120 is configured to receive the second strap 216. Each of the pair of first engagement members 122, 124 is configured to engage one of the plurality of second movement restriction members 226 of the second strap 216. For example, as shown in FIG. 1, the second strap 216 has been received through the first opening 120. The first engagement member 124 has engaged one of the plurality of second movement restriction members 226.
The engagement between an engagement member and a movement restriction member, such as between the first engagement member 124 and the second movement restriction member 226, can prevent translation of the second strap 216 away from the first body 112. For example, the engagement may only allow the second strap 216 to move in a single direction relative to the first body 112, such that the second body 212 can only be drawn towards the first body 112 as the second strap 216 is received through one of the first openings 118, 120.
Each of the pair of second openings 218, 220 is configured to receive the first strap 116. Each of the pair of second engagement members 222, 224 is configured to engage one of the plurality of first movement restriction members 126 of the first strap 116. For example, as shown in FIG. 1, the first strap 116 has been received through the second opening 218. The second engagement member 222 has engaged one of the plurality of first movement restriction members 126.
In some embodiments, a strap (e.g., first strap 116, second strap 216, etc.) is received by a corresponding opening by first passing the distal end of the strap through the corresponding opening, followed by passing the length of the strap through the opening up to a particular movement restriction member.
Similar to the engagement between the first engagement members 122, 124 and the second movement restriction members 226, the engagement between the second engagement members 222, 224 and the first movement restriction members 126 can prevent translation of the first strap 116 away from the second body 212. For example, the engagement between the first engagement members 122, 124 and the second movement restriction members 226 may only allow the first strap 116 to move in a single direction relative to the second body 212. As such, the first body 112 can only be drawn towards the second body 212 as the first strap 116 is received through one of the second openings 218, 220. Stated in other words, such an engagement prevents translation of the first strap 116 away from the second body 212 by preventing a motion between the first strap 116 and the second body 212 in which the first strap tie 110 and the second strap tie 210 are separated and/or in which the first body 112 and the second body 212 are drawn away from each other.
Similarly, the engagement between the second engagement members 222,224 and the first movement restriction members 126 may only allow the second strap to move in a single direction relative to the second body 212. As such, the second body 212 can only be drawn towards the first body 112 as the second strap 216 is received through one of the first openings 118, 120. Stated in other words, such an engagement prevents translation of the second strap 216 away from the first body 112 by preventing a motion between the second strap 216 and the first body 112 in which the second strap tie 210 and the first strap tie 110 are separated and/or in which the first body 112 and the second body 212 are drawn away from each other.
In some embodiments, an engagement member such as engagement member 222 is configured to removably engage a corresponding movement restriction member 126. For example, the engagement member 222 may be mechanically coupled to a release member that disengages the engagement member 222 from the movement restriction member 126 when the release member is actuated.
In some embodiments, the first strap tie 110 includes a first handle 136 disposed at the first distal end 130 of the first strap 116. As shown in FIG. 1, the first handle 136 has a tapered shape (e.g., tapers to a thin shape at the first distal end 130), facilitating the passing of the first strap 116 through an opening such as the second opening 218. In some embodiments, the first handle 136 is detachably coupled to the first strap 116.
In some embodiments, similar to the first strap tie 110, the second strap tie 210 includes a second handle 236 disposed at the second distal end 230 of the second strap 216. As shown in FIG. 1, the second handle 236 has a tapered shape (e.g., tapers to a thin shape at the distal end 230), facilitating the passing of the second strap 216 through an opening such as the first opening 120. In some embodiments, the second handle 236 is detachably coupled to the second strap 216.
Handles, such as the first handle 136 and the second handle 236 may include a high-friction surface, such as a surface with ridges or other protrusions, facilitating gripping of the handles by a user. Handles may include a grip shaped to conform to the hand of a user, such as a pistol grip. Handles may be integrally formed with associated straps, such as being extruded as a single piece. Handles may be detachably coupled by having complementary mating features with associated straps. For example, a handle may include a male protrusion configured to engage a female receiver provided on a distal end of a corresponding strap, or vice versa. A strap may be provided with a universal receiver or a universal protrusion, allowing the strap to be engaged to a variety of handles.
In some embodiments, the first strap tie 110 includes an attachment member configured to attach the first strap tie 110 to a portion of skin (e.g., a first portion of skin along a first side of a wound), such as an attachment member 134 disposed proximate to the base 114. The attachment member 134 may secure the strap tie 110 to the portion of skin. In some embodiments, the attachment member 134 may detachably secure, attach, or otherwise couple the strap tie 110 to the portion of skin. For example, the attachment member 134 can be an adhesive or staple that is removable and therefore can detachably secure the strap tie 110 to the portion of the skin. The attachment member 134 can secure the strap tie 110 temporarily. In some embodiments, the strap tie 110 can be permanently secured to the portion of skin (e.g., detachably secured, removably secured, temporarily secured, permanently secured, etc.). As shown in FIG. 1, the attachment member 134 is provided as a staple. In various embodiments, the attachment member 134 may be provided using various implements (e.g., staples, hooks, adhesives, etc.).
Similar to the first strap tie 110, in some embodiments, the second strap tie 210 includes an attachment member configured to attach the second strap tie 210 to a portion of skin (e.g., a second portion of skin along a second side of a wound), such as an attachment member 234 disposed proximate to the base 214. The attachment member 234 may secure the strap tie 210 to the portion of skin. In some embodiments, the attachment member 234 may detachably secure, attach, or otherwise couple the strap tie 210 to the portion of skin. For example, the attachment member 234 can be an adhesive or staple that is removable and therefore can detachably secure the strap tie 210 to the portion of skin. The attachment member 234 can secure the strap tie 210 temporarily. In some embodiments, the strap tie 210 can be permanently secured to the portion of skin (e.g., detachably secured, removably secured, temporarily secured, permanently secured, etc.). As shown in FIG. 1, the attachment member 234 is provided as a staple. In various embodiments, the attachment member 234 may be provided using various implements (e.g., staples, hooks, adhesives, etc.).
In some embodiments, as shown in FIG. 1, when the first strap 116 has been received through the second opening 218 and the second strap 216 has been received through the first opening 120, the first strap 116 and the second strap 216 are disposed substantially parallel to each other. In some embodiments, straps are disposed substantially parallel when they follow a similar path while being disposed proximate to each other when the strap ties 110, 210 are engaged. For example, a plane passing through the first strap 116 that is perpendicular to the first movement restriction members 126 of the first strap 116 may be parallel to a plane passing through the second strap 216 that is perpendicular to the second movement restriction members 226 of the second strap 216. At the same time, any given movement restriction member of a strap has an adjacent movement restriction member of the other strap disposed above or below, depending on which strap has been received into an upper opening of the other strap. In some embodiments, straps are disposed substantially parallel to each other when the straps would be aligned and adjacent to each other when drawn taut. In some embodiments, the first strap 116 and the second strap 216 are disposed in contact with each other.
In some embodiments, the straps 116, 216 can be substantially parallel even when they include flexible material. For example, the strap tie assembly 100 may undergo transient perturbations in configuration, orientation, shape, etc. during use; nevertheless, over time the straps 116, 216 will remain substantially parallel as described above.
In some embodiments, the straps 116, 216 are drawn taut once received by an opening in an opposing strap tie (e.g. strap ties 110, 210), because the distance between the first body 112 and the second body 212 corresponds to the lengths of the segments of the straps 116, 216 that are disposed between the first body 112 and the second body 212 (e.g., in an inner/interior region of the strap tie assembly 100).
In some embodiments, the first body 112 and the second body 212 are disposed on a region of skin (e.g. a region of skin including a first portion of skin, a wound, and a second portion of skin) that includes a curved profile. The first strap 116 and the second strap 216 may be substantially parallel by maintaining straight paths (e.g., paths of shortest distance) between the first body 112 and the second body 212 once received by the appropriate opening in an opposing strap tie. In some embodiments, substantially parallel includes a tolerance of a small difference in angle between the vectors defined by two components (e.g. less than 30 degrees, less than 20 degrees, less than 10 degrees, less than 5 degrees, less than 1 degree, etc.).
Referring now to FIG. 2 a perspective view of an embodiment of the strap tie assembly 100 is shown with the first base 114 and the second base 214 having extended base sections. In some embodiments, the first base 114 includes a first base extension 142 extending between a first proximal base end 138 and a first distal base end 140. The first proximal base end 138 is disposed proximate to the first body 112 of the first strap tie 110. The first base 114 may include a first base holder 144 protruding from a length of the first base extension 142. The first base holder 144 includes a groove 146 configured to hold a first base attachment member 148. The first base attachment member 148 may be similar in structure and function to the attachment member 134 shown in FIG. 1. A single first base attachment member 148, or a plurality of first base attachment members 148, may be provided to attach the first base extension 142 (and thus attach the first strap tie 110) to a portion of skin, facilitating the application of an even amount of force across a wound when the strap tie assembly 100 is used to secure or close a wound. While FIG. 2 shows the first base attachment members 148 as staples, the first base attachment members 148 need not be provided as identical implements.
In some embodiments, similar to the first base 114, the second base 214 includes a second base extension 242 extending between a second proximal base end 238 and a second distal base end 240. The second proximal base end 238 is disposed proximate to the second body 212 of the second strap tie 110. The second base 214 may include a second base holder 244 protruding from a length of the second base extension 242. The second base holder 244 includes a groove (e.g., hole, cavity, recess, depression, etc.) such as a groove 246 configured to hold a second base attachment member 248. The second base attachment member 248 may be similar in structure and function to the attachment member 234 shown in FIG. 1. A single second base attachment member 248, or a plurality of second base attachment members 248, may be provided to attach the second base extension 242 (and thus to attach the second strap tie 210) to a portion of skin, facilitating the application of an even amount of force across a wound when the strap tie assembly 100 is used to secure or close a wound. While FIG. 2 shows the second base attachment members 248 as staples, the second base attachment members 248 need not be provided as identical implements. In various embodiments, the strap ties 110, 210 may be secured to portions of skin at various distances from the wound, in order to apply a specific or selected tension (e.g., in order to apply an even amount of force across the wound).
As shown in FIG. 2, the first base extension 142 extends in a direction substantially parallel to the portion of the second strap 216 disposed between the first body 112 and the second distal end 230 of the second strap 216 (e.g., an outside portion of the second strap 216) when the second strap 216 has been received by and passed through the first body 112. The first base extension 142 similarly extends in a direction perpendicular to a plane defined by one or both of the faces of the openings 118, 120. The direction may be substantially parallel similar to a manner as described above for the orientation relationship between the first strap 116 and the second strap 216 when the straps 116, 216 have been received by openings of an appropriate strap tie. In some embodiments, the direction is substantially parallel when the vectors corresponding to the angles at which the first base extension 142 extends from the first body 112 and the outside portion of the second strap 216 exits the first body 112 are substantially parallel.
The first base extension 142 extends in a direction substantially opposite to that of the first strap 116 (e.g., the first strap 116 extends from the first body 112 towards the second body 212 so that the second body 212 may receive the first strap 116, whereas the first base extension 142 extends away from the second body 212).
Similar to the first base extension 142, the second base extension 242 extends in a direction generally parallel to the portion of the first strap 116 disposed between the second body 212 and the second distal end 130 of the first strap 116 (e.g., an outside portion of the first strap 116) when the first strap 116 has been received by and passed through the second body 212. The second base extension 242 similarly extends in a direction perpendicular to a plane defined by one or both of the faces of the second openings 218, 220. The second base extension 242 extends in a direction generally opposite the second strap 216 (e.g., the second strap 216 extends from the second body 212 towards the first body 112 so that the first body 112 may receive the second strap 216, whereas the second base extension 242 extends away from the first body 112).
Referring now to FIGS. 3-5, embodiments of the strap tie assembly 100 are shown in which the strap tie assembly 100 is disposed in a configuration in which the first strap tie 110 and the second strap tie 210 are drawn together more closely than in FIG. 2. That is, after the first strap 116 has been received and passed through the second upper opening 200 and the second strap 216 has been received and passed through the first lower opening 118, the first strap 116 and the second strap 216 have been translated (e.g., pulled, drawn, etc.) further in opposite directions, tightening the strap tie assembly 100. For example, a user may grasp the first strap 116 and the second strap 216 at the first handle 136 and the second handle 236, respectively, and apply force to the first strap 116 and the second strap 216 in opposite directions (e.g., draw the first handle 136 away from the second body 212 and draw the second handle 236 away from the first body 112, etc.).
In some embodiments, the first base 114 has been secured to a first portion of skin disposed on one side of a wound, and the second base 214 has been secured to a second portion of skin disposed on another side of a wound; drawing the first strap 116 and the second strap 216 apart (e.g., in opposite directions) results in the wound being drawn together to be closed, as the first portion of skin and the second portion of skin are drawn together due to force applied to the first base 114 and the second base 214 via the first strap 116 and the second strap 216.
In some embodiments, the interaction between the engagement members of the strap ties 110, 210 (e.g., engagement members 122, 124, 222, 224 shown in FIG. 1, etc.) and the movement restriction members of the strap ties 110, 210 (e.g., movement restriction members 126, 226, etc.) allows a user to adjust the position of the strap ties 110, 210 relative to the bodies 112, 212 in specific and/or discrete amounts. For example, in some embodiments, a user may count or otherwise keep track of the distance a strap has been drawn through a body of a remote strap tie (e.g., strap 116 and body 212 of remote strap tie 210, etc.) based on the number movement restriction members 126, 226 that have been passed through the bodies 212, 112, respectively.
In some embodiments, the movement restriction members 126 and/or the movement restriction members 226 are spaced in a specific pattern, allowing the manipulation of the strap ties 110, 210, and thus the force applied across a wound, to be controlled and adjusted in a specific manner. For example, in some embodiments, the movement restriction members proximate to a body (e.g., the first movement restriction members 126 of first strap 116 proximate to the first body 112 of the first strap tie 110, etc.) may be spaced apart by relatively large amounts, allowing for the strap to be translated in relatively large amounts through a remote body, while the movement restriction members distal from the body may be spaced apart by relatively small amounts, allowing for the strap to be translated in relatively small amounts through the remote body. In some embodiments, the movement restriction members are spaced apart equally.
Referring now to FIG. 6, a detailed perspective view of an embodiment of a strap tie 110 is shown. The strap tie 110 includes a body 112, a base 114 configured to be disposed adjacent to a portion of skin, and a strap extending from the body 112. The strap tie 110 also includes an upper opening 120 and a lower opening 118. Each of the openings 118, 120 are configured to receive a strap from a remote strap tie (e.g., strap tie 210, etc.). The strap tie 110 also includes an upper engagement member 124 disposed within the upper opening 120, and a lower engagement member 122 disposed within the lower opening 118. As shown in FIG. 6, the engagement members 122, 124 are disposed in opposing directions; the upper engagement member 124 and the lower engagement member 122 each curve towards a central face 150 disposed between the upper opening 120 and the lower opening 118. As such, each of the openings 118, 120 may receive a strap (e.g., second strap 216 shown in FIGS. 1-5, etc.), between the central face 150 and the respective engagement member 122, 124.
As shown in FIG. 6, the upper engagement member 124 and the lower engagement member 122 are each provided as a pawl. For example, the lower engagement member includes a recess 160 defined by a vertical edge 162 and an angled edge 164. When a movement restriction member of a remote strap tie (e.g., movement restriction member 226 shown in FIG. 1, etc.) engages the lower engagement member 122, the movement restriction member 226 fits into (e.g., is received by, engages, removably couples to, etc.) the recess 160. The engagement between the lower engagement member 122 and the movement restriction member 226 allows translation of the strap associated with the movement restriction member 226 (e.g., strap 216 shown in FIG. 1, etc.) in one direction, when the movement restriction member 226 slides along the angled edge 164, while preventing translation of the movement restriction member 226 in another direction (e.g., an opposite direction), when the movement restriction member 226 abuts the vertical edge 162.
In some embodiments, the movement restriction members 126 are disposed at an angle, facilitating an engagement with the engagement member 122 in which the remote strap (e.g., strap 216 shown in FIG. 1, etc.) is prevented from being translated away from the body 112. In some embodiments, the movement restriction members 126 are provided on multiple outer surfaces of the strap 116, such as an upper surface 132 and a lower surface 133. For example, the movement restriction members 126 may originate in pairs from a central body of the strap 116. The movement restriction members 126 may be provided as single movement restriction members that pass through from the upper surface 132 to the lower surface 133. As such, both the upper surface 132 and the lower surface 133 of the strap 116 may be engaged by an engagement member of a remote strap (e.g., engagement member 222 shown in FIG. 1, etc.). This underscores the modularity of the strap tie assembly 100, as the strap ties 110, 210 may be interchangeably manipulated and engaged. Such modular features facilitate using the strap tie assembly 100 in situations when the strap tie assembly 100 is to be quickly implemented, including but not limited to trauma or battlefield situations.
Referring now to FIG. 7, a detailed perspective view of an embodiment of the strap tie 110 (e.g., a first strap tie 110, etc.) receiving a remote strap 216 (e.g., a second strap 216 as shown in FIG. 1, etc.) is shown. The remote strap 216 has been received through upper opening 120 and engaged by engagement member 124. In various embodiments, the remote strap 216 may also be received through lower opening 118 and engaged by engagement member 122.
Referring further to FIGS. 6-7, the attachment member 134 is shown as contrasted between a pre-secured state and a secured state. As shown in FIG. 6, the attachment member includes two attachment arms 135a, 135b. As shown in FIG. 7, the attachment arms 135a, 135b have been translated/shifted, such as in order to attach the attachment member 134 to a portion of skin. For example, as shown in FIGS. 6-7, the attachment member 134 is a staple, which may be attached to a portion of skin using a tool such as a staple gun, etc.
Referring now to FIGS. 8-9, a strap tie assembly 300 is shown. The strap tie assembly 300 is similar in function to the strap tie assembly 100 shown in FIGS. 1-7. FIG. 8 shows a perspective view of an embodiment of the strap tie assembly 300. FIG. 9 shows a detailed perspective view of an embodiment of the strap tie assembly 300. The strap tie assembly 300 includes a first strap tie 310 and a second strap tie 410. The first strap tie 310 includes a first body 312, a first strap 316 attached to and/or extending from the first body 312, and a first base 314 attached to and/or extending from the first body 312. The first body 312 includes a first left opening 318 and a first right opening 320 disposed proximate to the first proximal end 328 of the first strap 316. Similarly, the second strap tie 410 includes a second body 412, a second strap 416 attached to and/or extending from the second body 412, and a second base 414 attached to and/or extending from the second body 412. The second body 412 includes a second left opening 418 and a second right opening 420 disposed proximate to the second proximal end 428 of the second strap 416. Such a configuration of openings in the first body 312 and the second body 412 may be referred to as “side-by-side,” based on the positions of the openings relative to each other and the respective bases 314, 414 of the bodies 312, 412 (in comparison, the openings 118, 120 and 218, 220 as shown in FIGS. 1-7 may be considered to have upper/lower positions relative to each other and the respective bases 114, 214 of the bodies 112, 212). In some embodiments, a plane passing through the openings of a body (e.g., first left opening 318 and first right opening 320 of first body 312; second left opening 418 and second right opening 320 of second body 412, etc.) is perpendicular to a longitudinal axis defined by a strap (e.g., strap 316, strap 416, etc.) and/or parallel to a transverse axis passing through both the first strap 316 and the second strap 416 when the first strap 316 and the second strap 416 have been received by an opposite (e.g., complementary, etc.) strap tie. The first strap 316 includes first movement restriction members 326, and the second strap 416 includes second movement restriction members 426.
The first body 312 may include an engagement member disposed in each of the first left opening 318 and the first right opening 320, such as an engagement member 324. The second body 412 may include an engagement member disposed in each of the second left opening 418 and the second right opening 420. Engagement members of the strap tie assembly 300, such as the engagement member 324, are similar in structure and function to the engagement members of the strap tie assembly 100.
As shown in FIG. 8, the first strap 316 includes a first loop handle 360 disposed at a distal end 330 of the first strap 316. The first loop handle 360 includes loops 364, 366 disposed between the distal end 330 of the first strap 316 and a distal end 368 of the first loop handle 360. Similar to the first loop handle 360, the second loop handle 460 includes loops 464, 466 disposed between the distal end 430 of the second strap 416 and a distal end 468 of the second loop handle 460. The first loop handle 360 and the second loop handle 460 facilitate manipulation of the straps 316, 416, for example, by providing handles to a user which are easy to grip and manipulate. While FIG. 8 shows the loop handles 360, 460 disposed in a plane generally containing the straps 316, 416, in various embodiments, the loop handles 360, 460 may be disposed in various orientations. In some embodiments, the strap tie assembly 300 includes flexible or malleable material (e.g., material that may yield or be rotated, etc.), allowing the loop handles 360, 460 to be manipulated at various angles. The loop handles 360, 460 may include material allowing the loop handles 360, 460 to be reduced in size (e.g., compressed, squeezed, etc.) so that the loop handles 360, 460 may be passed through an opening of a strap tie.
Referring now to FIGS. 10-11, a strap tie assembly 500 is shown. The strap tie assembly 500 is similar in structure and function to the strap tie assembly 300 shown in FIGS. 8-9. FIG. 10 is a perspective view of the strap tie assembly 500. The strap tie assembly 500 includes a first strap tie 510 and a second strap tie 610. As shown in FIG. 10, the strap tie assembly 500 includes a first loop handle 560 attached to a first strap 516, and a second loop handle 660 attached to a second strap 616.
FIG. 11 is a top view of an embodiment of the strap tie assembly 500. The first strap tie 510 includes a first inner body 512, a first outer body 513, a first strap 516 attached to and/or extending from the first inner body 512, and a first base 514. Similar to the first strap tie 510, the second strap tie 610 includes a second inner body 612, a second outer body 613, a second strap 616 attached to and/or extending from the second inner body 612, and a second base 614. The inner bodies 512, 612 are disposed on an “interior” of the strap tie assembly 500 (e.g., the region of the strap tie assembly 500 between the inner bodies 512, 612 is an interior or inner region, in which the straps 516, 616 overlap when the first strap tie 510 engages the second strap tie 610, while the regions outside of the outer bodies 513, 613 are exteriors or outer regions). The outer bodies 513, 613 are disposed distal from the interior of the strap tie assembly 500.
In some embodiments, the first inner body 512 includes a first inner opening 518 for receiving the second strap 616, and the first outer body 513 includes a first outer opening 520 for receiving the second strap 616 once the second strap 616 has been received through the first inner opening 518. Similarly, the second inner body 612 includes a second inner opening 618 for receiving the first strap 516, and the second outer body 613 includes a second outer opening 620 for receiving the first strap 516 once the first strap 516 has been received through the second inner opening 618. As such, each strap tie may include a pair bodies. As shown in FIG. 11, the first outer body 513 is attached to the first inner body 512 proximate to the first proximal end 528 of the first strap 516; similarly, the second outer body 613 is attached to the second inner body 612 proximate to the second proximal end 628 of the second strap 616. As shown in FIG. 11, the inner openings 518, 618 have a depth (e.g., the length of a strap that passes through the opening) that is greater than the depth of the outer openings 520, 620. In various embodiments, various modifications may be made to the sizes of the openings (e.g., the depth of the outer openings 520, 620 may be greater than the depth of the inner openings 518, 618).
In some embodiments, the first inner body 512 and the second inner body 612 are provided as movable elements that allow for disengagement (e.g., loosening, decoupling, separating) of the first strap tie 510 from the second strap 616, and/or for disengagement of the second strap tie 610 from the first strap 516. For example, the inner bodies 512, 612 may include an engagement member (e.g., an engagement member similar to the engagement members provided for strap tie assemblies 100, 300), and the inner bodies 512, 612 may be provided as a button or other actuator such that actuation (e.g., squeezing, pushing, sliding, etc.) of the inner bodies 512, 612 disengages the engagement members from a corresponding movement restriction member (e.g. movement restriction members 526, 626). In some embodiments, the engagement members are flexible, such that they respond to actuation by the inner bodies 512, 612 by deforming or otherwise changing in shape, and thus may be disengaged from the movement restriction members 526, 626.
In some embodiments, the straps 516, 616 are oriented at an angle (e.g., a 90-degree angle, etc.) relative to the bases 514, 614. For example, as shown in FIGS. 10-11, when the first strap tie 510 and the second strap tie 610 are engaged, a transverse axis that passes through the straps 516, 616 in the interior region of the strap tie assembly 500 is parallel to a plane generally containing the bases 514, 614. In other words, when the strap tie assembly 500 is assembled (e.g., the first strap tie 510 and the second strap tie 610 are engaged) and secured to portions of skin on either side of a wound, the movement restrictions members 526, 626 of each strap 516, 616 will both tend to face in a direction that does not intersect with the portions of skin or the wound.
Referring now to FIGS. 12-15, a strap tie assembly 700 is shown. The strap tie assembly is similar in structure and function to the strap tie assembly 500 shown in FIGS. 10-11. FIG. 12 is a perspective view of the strap tie assembly 700. The strap tie assembly includes a first strap tie 710 and a second strap tie 810. The first strap tie 710 includes a first body 712 that includes a single opening for receiving a second strap 816 of the second strap tie 810. Similarly, the second strap tie 810 includes a second body 812 that includes a single opening 818 for receiving a first strap 716 of the first strap tie 710. When the straps 716, 816 have been received by corresponding openings, the straps 716, 816 are disposed adjacent to and parallel to each other. A first base 714 extends from the first body 712, and similarly a second base 814 extends from the second body 812.
FIG. 13 shows a detail perspective view of a distal end 830 of the second strap 816. The distal end 830 has been provided with a second handle 860. As shown in FIG. 13, the second handle 860 is detachably coupled to a second strap handle 836 disposed at the distal end 830 of the second strap 816. The second handle 860 includes a second handle body 862 defining a second handle opening 864. The second handle opening 864 is configured to receive (e.g., detachably couple to, have inserted, engage) the second strap handle 836. In other words, the second handle 860 may be provided as a modular device to supplement the grip/handling provided by the second strap handle 836 of the second strap 816. The second handle 860 also includes a pair of handle lobes 866, 868 extending from an opposite end of the second handle body 862 from where the second handle opening 864 receives the second strap 816. In some embodiments, the handle lobes 866, 868 include lobe openings 870, 872, which may allow a user to further grip/handle the second handle 860 (e.g., to insert a finger through the lobe openings 870, 872, etc.). Referring back to FIG. 12, the distal end 730 of the first strap 716 may also be provided with a first handle 760 proximate to a first strap handle 736 of the first strap 716. The first handle 760 may be similar to or identical to the second handle 860. For example, the first handle 760 and the second handle 860 may be identical and interchangeable. As shown in FIG. 12, the first handle 760 includes a first handle body 762 for receiving the first strap 716 in a first handle opening 764, and a pair of first handle lobes 766, 768 extending from an opposite end of the first handle body 762 from where the first handle body 762 receives the first strap.
Referring further to FIGS. 14-15, detail views of the first strap tie 710 and the second strap tie 810 are shown in order to illustrate the operation of the engagement mechanism between the strap bodies 712, 812 and the straps 716, 816. The first strap tie 710 includes a first engagement member 722. The first strap tie 710 also includes a first engagement base 724 extending from the first body 712. The first engagement base is disposed on an inward side of the first strap tie 710 (e.g., adjacent to the proximal end 728 of the first strap 716; etc.). The first engagement base 724 also includes an opening for receiving a strap from another strap tie. The first engagement member 722 includes a first engagement portion 742 for engaging a second movement restriction member 826 of the second strap 816, and a first actuator 740. The first actuator 740 may be manipulated (e.g., squeezed, translated, pushed, adjusted, etc.) in order to engage or disengage the first engagement portion 742 from the second movement restriction member 826. For example, as shown in FIGS. 14-15, the first actuator 740 may be squeezed towards the first engagement base 724 (e.g., substantially parallel to the direction that the second strap 816 passes through the opening of the first strap tie 710), in order to disengage the first engagement portion 742 from the second movement restriction member 826.
The second strap tie 810 may include a similar or identical engagement mechanism as provided for the first strap tie 710. For example, as shown in FIGS. 12, 14, and 15, the second strap tie 810 receives the first strap 716 through a second opening 818 of a second engagement base 824. A second engagement portion 842 of a second engagement member 822 is configured to engage a first movement restriction member 726 of the first strap 716. A second actuator 840 may be manipulated in order to engage or disengage the second engagement portion 842 from the first movement restriction member 726. The second engagement base 824 is disposed on an inward side of the second strap tie 810, such that the second opening 818 is disposed adjacent to the proximal end 828 of the second strap 816. The second engagement base 824 is provided continuous with a plane defined by the second opening 818, perpendicular to the direction through which the first strap 716 is received through the second opening 818. As such, when each strap tie 710, 810 has received a strap 716, 816 from the other strap tie, the straps 716, 816 are disposed adjacent and parallel to each other.
Referring now to FIGS. 16-19, a strap tie assembly 900 is shown. The strap tie assembly 900 is similar in structure and function to the strap tie assembly 700 shown in FIGS. 12-15. The engagement mechanism of the strap tie assembly 900 is similar to the engagement mechanism of the strap tie assembly 700. A first strap tie 910 includes a first strap body 912. The first strap body 912 includes a first engagement member 922 that can engage/disengage a second movement restriction member 1026 of a second strap 1016 of the second strap tie 1010, for example by squeezing the first engagement mechanism 922 towards a first engagement body 924. The first strap body 912 includes a first opening 918 disposed adjacent to a proximal end 928 of the first strap 916. The first engagement member 922 is disposed above (e.g., on an opposite side of the first strap body 912 from a first base 914 of the first strap body 912) the first opening 918, and can be actuated (e.g., squeezed) in a direction perpendicular to a direction that a second strap 1016 may be received through the first opening 918.
The second strap tie 1010 may be similar or identical to the first strap tie 910. As shown in FIGS. 16 and 19, the second strap tie 1010 includes a second strap body 1012. The second strap body 1012 includes a second engagement member 1022 that can engage/disengage a first movement restriction member 926 of the first strap 916, for example by squeezing the second engagement member 1022 towards a second engagement body 1024. The second strap body 1012 includes a second opening 1018 disposed adjacent to a proximal end 1028 of the second strap 1016. The second engagement member 1022 is disposed above (e.g., on an opposite side of the second strap body 1012 from a second base 1014 of the second strap body 1012) the second opening 1018, and can be actuated)(e.g., squeezed) in a direction perpendicular to a direction that the first strap 916 may be received through the second opening 1018.
Referring further to FIGS. 16-19, the strap ties 910, 1010 include handles 936, 1036 extending from respective distal ends 930, 1030 of the strap ties 910, 1010. The handles 936, 1036 are provided with handle protrusions 938, 1038, to facilitate gripping of the handles 936, 1036 by a user. The handles 936, 1036 curve away from the bases 914, 1014 of the respective strap ties 910, 1010. Protrusions such as handle protrusions 938, 1038 provide indentations in between the handle protrusions 938, 1038.
Referring further to FIG. 17, a side detail view of the strap tie assembly 900 in the region of the second strap body 1012 is shown to illustrate particular features of the engagement mechanism and the handle 936. An upper surface 932 (e.g., a surface which is disposed on an opposite side of the first strap 916 from a portion of skin/a wound; a surface which is disposed on an opposite side of the first strap 916 from the second base 1014, etc.) of the first strap 916 includes first edge cavities 925. As shown in FIG. 17, the first edge cavities 925 include a biased shape, such that the first edge cavities 925 include a greater gradient towards the distal end 930 of the first strap 916. The first edge cavities 925 may act in a similar manner to an engagement mechanism such as an engagement member, in order to selectively or consistently prevent translation of the first strap tie 910 away from the second strap tie 1010. When the first edge cavities 925 include a biased shape, the first edge cavities 925 may be configured to engage a pawl in order to prevent translation of the first strap tie 910 away from the second strap tie 1010. In some embodiments, the first edge cavities 925 provide resistance to slipping, such as slipping that might occur between the first strap 916 and the hand(s) of a user when gripping the first strap 916, such as when the first strap 916 is covered in blood, lipids, or other fluids. As shown in FIG. 19, the second strap 1016 may also include an upper surface 1032 including second edge cavities 1025, which may be similar to or identical to the first edge cavities 925. For example, the second edge cavities 1025 may also include a biased shape, such that when each of the straps 916, 1016 have been received by an opposing strap tie 1010, 910, the straps 916 are aligned parallel to and adjacent to one another, and the first edge cavities 925 and second edge cavities 1025 have an opposing orientation.
Referring back to FIG. 17, the first strap 916 may also include a lower surface 933 (e.g., a surface which is disposed on a side of the first strap 916 proximate to a portion of skin/a wound; a surface which is disposed on a side of the first strap proximate to the second base 1014; etc.), and the lower surface 933 may include first protrusions 927.
Referring now to FIG. 18, a perspective view is shown of a bottom or lower side of the strap tie assembly 900 (e.g., the side of the strap tie assembly 900 to be disposed proximate to a portion of skin/a wound, etc.). FIG. 18 illustrates the first protrusions 927 disposed along the lower surface 933 of the first strap 916, and the second protrusions 1027 disposed along the lower surface 1033 of the second strap 1016. The second protrusions 1027 may be similar or identical to the first protrusions 927. For example, as shown in FIG. 18, the protrusions 927, 1027 have similar spacing along the respective lower surfaces 933, 1033, and include similar shapes provided by two equal and opposite angled edges. In various embodiments, the protrusions 927, 1027 may include various shapes, such as shapes biased towards one side, rectangular solids, trapezoidal solids, curved or elongated solids, etc. As shown in FIGS. 17 and 18, the protrusions 927, 1027 extend a distance away from respective surfaces 933, 1033 such that the protrusions 927, 1027 will not contact a wound or a portion of skin when at least one of the bases 914, 1014 contacts a wound or a portion of skin. In some embodiments, the protrusions 927, 1027 extend a distance away from respective surfaces 933, 1033 such that the protrusions 927, 1027 are configured to engage openings with the corresponding opposing strap bodies 1012, 912. In some embodiments, the protrusions 927, 1027 provide resistance to slipping, such as slipping that may occur between straps 916, 1016 and the hand(s) of a user when gripping the straps 916, 1016, such as when the straps 916, 1016 are covered in blood, lipids, or other fluids.
Referring further to FIG. 19, a detail perspective view of the strap tie assembly 900 proximate to the second strap tie 1010 is shown to illustrate features of the engagement mechanisms of the strap tie assembly 900. The second strap 1016 includes the second movement restriction members 1026 and the second edge cavities 1025 as being biased towards the “right” based on the orientation shown (e.g., the second strap 1016 extends in a first direction away from the second strap body 1012, and the second movement restriction members 1026 are biased in a second direction opposite to the first direction). Similarly, because the first strap 916 is disposed parallel and adjacent to the second strap 1016 while extending in an opposite direction as the second strap 1016 (e.g., extending from the first strap body 910 shown in FIG. 16, etc.), the first movement restriction members 926 and the first edge cavities 925 are biased towards the “left” based on the orientation shown. The biased orientation (e.g., disposed at an angle relative to a plane defined by a respective strap 916, 1016, etc.) of the movement restriction members 926, 1026 facilitates preventing translation of a strap away from an engagement member. For example, when the first strap 916 has been received through the second opening 1018, the engagement between the second engagement member 1022 and the first movement restriction members 926 allows the first strap 916 to be drawn towards the “right” so that a distance between the second strap tie 1010 and a first strap tie (e.g., first strap tie 910 shown in FIG. 16, etc.) decreases, while preventing translation of the first strap 916 in a manner in which a distance between the second strap tie 1010 and the first strap tie 910 would increase. This one-directional engagement and translation mechanism may also apply to the interaction between the second strap 1016 and the first strap tie 910, and between the edge cavities 925, 1025 and corresponding opposing strap ties 1010, 910.
As shown in FIG. 19, the second engagement member 1022 may be manipulated (e.g., adjusted, pushed, squeezed, etc.) by being translated towards the second engagement base 1024. When the second engagement member 1022 is manipulated, the second engagement member 1022 no longer engages a first movement restriction member 926 of the first strap 916, such that the first strap 916 may be translated both in a first direction “towards” the second strap tie 1010 such that a distance between the first strap tie 910 and the second strap tie 1010 decreases, and a second direction “away” from the second strap tie 1010 such that a distance between the first strap tie 910 and the second strap tie 1010 increases. In some embodiments, the biasing of the edge cavities 925, 1025 is great enough to aid in preventing translation of the strap ties 910, 1010 away from each other, but such biasing is not sufficient to independently prevent translation of the strap ties 910, 1010 away from each other when one or both of the engagement members 922, 1022 have been disengaged from corresponding movement restriction members 1026, 926. In some embodiments, the edge cavities 925, 1025 provide resistance to slipping, such as slipping that may occur between the straps 916, 1016 and the hand(s) of a user when gripping the straps 916, 1016, such as when the straps 916, 1016 are covered in blood, lipids, or other fluids.
Referring now to FIGS. 20-22, a strap tie assembly 1100 is shown. The strap tie assembly 1100 is similar in structure and function to the strap tie assembly 900. FIG. 20 is a perspective view of the strap tie assembly 1100. The strap tie assembly 1100 includes a first strap tie 1110 and a second strap tie 1210. The first strap tie 1110 includes a first strap body 1112, a first base 1114 extending from the first strap body 1112, a first strap 1116 extending from the first strap body 1112, and an engagement mechanism for engaging a strap from another strap tie including a first engagement member 1122 and a first engagement base 1124. First movement restriction members 1126 are provided along the first strap 1116. Similarly, the second strap tie 1210 includes a second strap body 1212, a second base 1214 extending from the second strap body 1212, a second strap 1216 extending from the second strap body 1212, and an engagement mechanism for engaging a strap from another strap tie including a second engagement member 1222 and a second engagement base 1224. Each of the straps 1116, 1216 includes respective movement restriction members 1126, 1226.
Referring further to FIG. 21, a detail perspective view of the second strap tie 1210 is shown to illustrate the engagement mechanism of the second strap tie 1210, such as when a first strap 1116 is received in a second opening 1218 of the second strap tie 1210. The second engagement member 1222 is similar to the second engagement member 1022 shown in FIGS. 16-19, and the second engagement base 1224 is similar to the second engagement base 1024 shown in FIGS. 16-19. The second engagement member 1222 and the second engagement base 1224 each extend a further distance away (e.g., in a direction away from where the strap tie assembly 1100 would be disposed along a portion of skin or along a wound) from the second strap body 1212 than the similar second engagement member 1022 and second engagement base 1024.
Referring further to FIG. 22, a detail perspective view is shown of a bottom or lower side of the strap tie assembly 1100 (e.g., a side of the strap tie assembly 1100 proximate to where the second base 1214 may be disposed adjacent to a portion of skin or a wound, etc.) in the vicinity of the second strap body 1212. The first strap 1116 includes protrusions 1127 disposed along a lower surface 1133 of the first strap 1116. As compared to the protrusions 927 of the first strap 916 shown in FIGS. 16-19, the protrusions 1127 of the first strap 1116 are provided only along a distal region of the lower surface 1133 (e.g., a region of the lower surface 1133 running only partially from the distal end 1130 towards a proximal end 1128 as shown in FIG. 20). For example, as shown in FIG. 22, the region of the lower surface 1233 of the second strap 1216 (which may be similar or identical to the first strap 1116) that is proximate to the proximal end 1228 does not include protrusions. As such, protrusions may be selectively provided such that they would not be disposed directly above a wound when the strap tie assembly 1100 is attached to portions of skin adjacent to the wound. In various embodiments, various numbers and groupings of protrusions may be provided along lower surfaces of straps of the strap tie assembly 1100 based on whether the protrusions would be disposed above a wound, how tightly the strap tie assembly 1100 is expected to be drawn together, how often the strap tie assembly 1100 is expected to be adjusted, etc. As shown in FIG. 22, the protrusions 1127 are biased towards the “left” based on the orientation shown in the figure (e.g., the protrusions 1127 extend further away from the lower surface 1133 on a side of the protrusions 1127 that is closer to the proximal end 1128 than the distal end 1130, etc.). Providing the protrusions 1127 with a such a bias may facilitate manipulation of the strap tie assembly 1100 in which the engagement between the second strap tie 1210 and the first strap 1116 prevents translation of the first strap tie (see, e.g., first strap tie 1110 shown in FIG. 20) away from the second strap tie 1210. In various embodiments, various biases may be provided to protrusions such as the protrusions 1127 in order to select the resistance that the protrusions 1127 provide against translation of the first strap 1116 in a certain direction.
Referring now to FIGS. 23-26, a strap tie assembly 1300 is shown. The strap tie assembly 1300 is similar in structure and function to the strap tie assembly 1100 shown in FIGS. 20-22. FIG. 23 is a perspective view of the strap tie assembly 1300. The strap tie assembly includes a first strap tie 1310 and a second strap tie 1410. FIGS. 24-26 are detailed side, bottom, and end perspective views of the strap tie assembly 1300 in the vicinity of the second strap tie 1410, illustrating features of the engagement mechanism and the straps of the strap tie assembly 1300. The first strap tie 1310 includes a first strap body 1312, with a first strap 1316 extending from the first strap body 1312. A first base 1314 extends from the first body. The first strap tie 1310 includes a first engagement member 1322 and a first engagement base 1324 that are similar to the first engagement member 922 and the first engagement base 924 shown in FIGS. 16-19, with wider profiles (e.g., a length of the first engagement member 1322 along an axis parallel to the first strap 1316 is greater than a similar length of the first engagement member 922; a length of the first engagement base 1324 along an axis parallel to the first strap 1316 is greater than a similar length of the first engagement base 924; etc.). Similarly, the second strap tie 1410 includes a second strap body 1412, and a second engagement member 1422 and a second engagement base 1424 that are similar to the second engagement member 1022 and the second engagement base 1024 shown in FIGS. 16-19, with wider profiles. The second engagement member 1422 may be similar or identical to the first engagement member 1322; the second engagement base 1424 may be similar or identical to the first engagement base 1324. A second strap 1416, which is similar to the first strap 1316, extends from a second proximal end 1428 adjacent to the second strap body 1412 to a second distal end 1430, with second movement restriction members 1426 disposed along the second strap 1416.
Referring further to FIG. 24, the first strap 1316 may terminate in a first handle region 1336 that extends towards a distal end 1330 of the first strap 1316. The first handle region 1336 is provided at an angle relative to the rest of the first strap 1316. As shown in FIGS. 23-26, when the strap tie assembly 1300 has been assembled, the first handle region 1336 extends at an angle away from the second base 1414. The first handle region 1336 includes protrusions 1338. The protrusions 1338 may be similar or identical to other protrusions disclosed herein (e.g., protrusions 927 shown in FIG. 18; protrusions 1127 shown in FIG. 23, etc.). In some embodiments, the first handle region 1336 is relatively elongated as compared to the first strap 1316 (e.g., a length of the first handle region 1336 may be greater than one half the length of the first strap 1316, greater than one quarter the length of the first strap 1316, greater than one eight the length of the first strap 1316, etc.). The second strap 1416 may also terminate in a second handle region 1436 that is similar or identical to the first handle region 1336. As shown in FIG. 23, the second strap 1416 may include protrusions 1438 that are similar or identical to other protrusions disclosed herein.
Referring further to FIG. 25, a lower surface 1340 of the first handle region 1336 (e.g., a surface disposed proximate to the second base 1414 when the first strap 1316 has been received by the second strap tie 1410) includes protrusions 1339. The protrusions 1339 may be similar or identical to the protrusions 1338. As shown in FIGS. 24-25, the protrusions 1338, 1339 are biased, facilitating manipulation of the strap tie assembly 1300 in which the engagement between the first strap 1316 and the second strap tie 1410 prevents translation of the first strap tie 1310 away from the second strap tie 1410. The second strap 1416 may also be provided with lower surface protrusions that are similar or identical to the protrusions 1339.
Referring further to FIG. 26, the second strap tie 1410 is configured to engage the first strap 1316 using a second engagement member 1422. The second engagement member 1422 includes a second engagement unit 1423 that may be disposed within a second opening 1418 of the second strap tie 1410. When the second strap tie 1410 receives the first strap 1316 through the second opening 1418, the second engagement unit 1423 engages a first movement restriction member 1326 of the first strap tie 1316. The first strap 1316 includes a first ramp region 1320 between the first movement restriction members 1326 and the first handle region 1336. The first ramp region 1320 may facilitate translation of the first strap 1316 through the second opening 1418, by providing a thickness gradient between the relatively thin first handle region 1336 and the relatively thick region of the first strap 1316 that includes the first movement restriction members 1326. The second strap 1416 may be similar or identical to the first strap 1316.
In various embodiments, multiple strap tie assemblies (e.g., strap tie assemblies 100, 300, 500, 700, 900, 1100, 1300) may be used to secure and/or close a wound, such as in a strap tie grouping. For example, a first strap tie assembly 100 may be disposed across a first region of a wound in order to secure the first region of the wound, and a second strap tie assembly 300 may be disposed across a second region of a wound in order to secure the second region of the wound. The wound regions may have similar properties (e.g., cross-wound distance, healing status, etc.) and the strap tie assemblies may be drawn to similar tightness in order to apply an even amount of force across the wound. The wound regions may have different properties and the strap tie assemblies may be drawn to different tightnesses in order to apply an even amount of force across the wound. Various numbers and lengths of strap ties and strap tie assemblies may be used to secure and/or close the wound (e.g., depending on the location of the body where the wound has occurred; the curvature of the skin; the sensitivity of regions near the wound such as organs, joints, facial structures; etc.). In some embodiments, a strap tie grouping includes multiple strap ties for each side of a wound joined together. The multiple strap ties may be joined together with a tie, a line, a thread, a strip, etc. The multiple strap ties may be joined together with a strip of adhesive, such that the multiple strap ties may be held in place together and also attached to a portion of skin. In some embodiments, a strap tie grouping includes between two and five strap ties for each side of a wound.
Referring now to FIGS. 27-30, multiple strap tie assemblies 1300 are provided together as a strap tie grouping 1500. The strap tie grouping 1500 is disposed across a wound 10, with a set of first strap ties 1310 disposed on a first portion of skin 12, and a set of second strap ties 1410 disposed on a second portion of skin 14. The strap tie grouping 1500 may be attached to the skin in any manner as described herein. As shown in FIGS. 27-30, the strap tie assemblies 1300 have been adjusted to different tightnesses (e.g., the distance between the first strap body 1312 and the second body 1412), such that the wound tapers from a relatively thin portion at the outer edges 16, 18 to a relatively thick portion in the center 20. In various embodiments, various qualities of the wound may be used to determine how tightly each strap tie assembly 1300 is adjusted in order to variously tighten portions of skin across the wound.
Referring now to FIG. 31, a block diagram of an embodiment of a method 1600 of securing a wound using a strap tie system is shown. The method may be implemented using any of the strap tie assemblies and devices disclosed herein, such as strap tie assemblies 100, 300, 500. A variety of users may perform the method, including but not limited to an individual having a wound, a medical care professional (e.g., doctor, nurse, etc.), a patient, a trauma care provider, a field care provider, a civilian, a soldier, etc.
At 1610, a first strap tie is secured adjacent to a first portion of skin on a first side of a wound, and a second strap tie is secured adjacent to a second portion of skin on a second side of a wound. The strap ties may be secured in any manner as disclosed herein (e.g., detachably secured, attached, removably coupled, etc.). The strap ties may be secured using attachment members (e.g., staples, hooks, adhesives, etc.). In various embodiments, the strap ties are secured to the portions of skin at various distances from the wound (e.g., a selected distance from the wound), in order to apply a specific amount of force and/or tension across the wound (e.g., an even amount of force across the wound). In some embodiments, a user can secure the first strap tie adjacent to the first portion of skin on the first side of the wound, and a user can secure the second strap tie adjacent to the second portion of skin on the second side of the wound. In some embodiments, a user can select the distance from the wound that at least one of the first strap tie and the second strap tie is secured to a respective portion of skin.
At 1620, each strap tie receives a strap from the other strap tie. For example, the first strap tie receives a second strap from the second strap tie, through a first opening in a first body of the first strap tie, and the second strap tie receives a first strap from the first strap tie, through a second opening in a second body of the second strap tie. In some embodiments, a user can receive the second strap from the second strap tie through the first opening in the first body of the first strap tie by drawing (e.g., pulling, threading, pushing, etc.) the second strap through the first opening. Similarly, a user can receive the first strap from the first strap tie through the second opening in the second body of the second strap tie by drawing the second strap through the second opening. In some embodiments, the strap ties are already assembled as a strap tie assembly, so that a user (e.g., a medic, a surgeon, a technician, etc.) can tighten the straps (see 1630) immediately after securing the strap tie assembly.
At 1630, candidate movement restriction members are selected for engaging with engagement members of each tie strap. For example, a first candidate movement restriction member disposed along a surface of the first strap is selected, in order to be engaged by a second engagement member of the second strap tie. Similarly, a second candidate movement restriction member disposed along a surface of the second strap is selected, in order to be engaged by a first engagement member of the first strap tie. The candidate restriction members may be selected in order to apply an even amount of force across the wound. The candidate restriction members may be selected in order to draw each strap a certain distance through an opening of the other strap. The candidate restriction members may be selected based on an effect on the portions of skin or on the wound, such as a distance between the portions of skin as the wound is closed, etc. In some embodiments, a user can select the first candidate restriction member for the first strap, and a user can select the second candidate restriction member for the second strap.
At 1640, the engagement members are engaged to the respective candidate movement restriction members. For example, the first engagement member of the first strap tie is engaged to the second candidate movement restriction member, and the second engagement member of the second strap tie is engaged to the first candidate movement restriction member. Engagement members and movement restriction members may be engaged by drawing the straps a certain distance through respective openings of the strap ties until the engagement members are aligned with/engage the appropriate movement restriction member. A user can engage the first engagement member to the second candidate movement restriction member by aligning the first engagement member with the second candidate movement restriction member and engaging, joining, attaching, or otherwise coupling the first engagement member and the second candidate movement restriction member. A user can engage the second engagement member to the first candidate movement restriction member by aligning the second engagement member with the first candidate movement restriction member and engaging, joining, attaching, or otherwise coupling the second engagement member and the first candidate movement restriction member.
At 1650, a wound status is identified. The wound status may relate to various qualities and properties of the wound, including but not limited to the health of the wound, the presence of any infections in the wound, the size of the wound (e.g., the distance between the first portion of skin on one side of the wound and the second portion of skin on the other side of the wound, etc.), any relative changes in the wound, the structural integrity of the wound (including inflation), the elasticity of the wound, tissue, or skin, etc. A user may identify the wound status, such as by observing the wound, using a sensor or other medical device to non-invasively identify properties of the wound, performing a test on the wound or material within the wound, measuring visible properties of the wound, etc.
At 1660, a determination is made as to whether the wound status is satisfactory. For example, the wound status may be satisfactory if the wound is healing properly. The wound status may be unsatisfactory if the wound is infected, if the portions of skin on either side of the wound need to be drawn more closely together, if the force applied across the wound is not even, etc. A user may determine whether the wound status is satisfactory by comparing the wound status to a heuristic, a flow chart, or any other plan or strategy relevant to wound closure and wound healing.
If the wound status is not satisfactory (e.g., unsatisfactory), then at 1670, the straps are adjusted to alter the positions of the strap ties and thus the portions of skin disposed on either side of the wound. In some embodiments, the wound status is not satisfactory because the force applied across the wound is not even. As such, at least one of the straps may be adjusted (e.g., drawn further through an opening of the other strap tie) in order to ensure that the force applied across the wound is even. A strap may be adjusted by grasping a portion of the strap (e.g., a distal end, etc.), and drawing the strap further (e.g., in a direction other than a direction in which the strap would be decoupled from the other strap tie) through the opening of the other strap tie. A user may adjust the positions of one or more strap ties by holding or otherwise grasping the strap of the strap tie, and drawing the strap further through the corresponding opening until a desired position is reached, such as a position at which the force applied across the wound is even.
If the wound status is satisfactory, then at 1680, the strap tie assembly may be removed (e.g., unsecured, desecured, etc.). For example, attachment members may be removed from the portions of skin on either side of the wound. A user may remove the attachment members manually, by using a tool for removing the attachment members, etc.
In some embodiments, adjusting the straps includes engaging the engagement members with a new candidate movement restriction member. For example, a wound status may be unsatisfactory because the force applied across the wound is not even. A new candidate first movement restriction member may be selected along the first strap, and the first strap may be adjusted by drawing the first strap further through an opening of the second strap tie, then engaging the new candidate first movement restriction member with the appropriate second engagement member. A user may identify a new candidate movement restriction member, adjust the position of the straps, and engage the engagement member to the corresponding movement restriction member.
In some embodiments, a strap tie assembly is secured across a wound in a particular order. For example, a first strap tie may be secured to a first portion of skin; next, a second strap may be received through a first opening in the first strap tie; next, the second strap tie from which the second strap extends may receive a first strap extending from the first strap tie; next, the second strap tie may be secured to a second portion of skin across a wound from the first portion of skin. In various embodiments, the order of these steps may be modified based on the availability of strap ties, the availability of attachment members, the status of the wound, the amount of time available to secure the wound, etc.
In some embodiments, the straps may be applied and reapplied from portions of skin adjacent to a wound. For example, a strap tie assembly may be used to secure a wound, then desecured (e.g., detached, removed, etc.) from the wound, then resecured (e.g., reattached, etc.) to the wound at a similar or different distance from or position relative to the wound, with a similar or different amount of force applied across the wound, etc. In some embodiments, a user may detach a strap tie assembly that was already secured to portions of skin adjacent to a wound from the portions of skin, and may reattach the strap tie assembly to the portions of skin.
While the present disclosure illustrates applications of a strap tie assembly for securing a wound, in various embodiments, a strap tie assembly may be used for various purposes, such as securing surfaces. For example, a strap tie assembly includes a first strap tie including a first base, a first body, and a first strap extending from the first body. The first base is configured to be disposed adjacent to a first surface. The first body includes a first opening and a first engagement member disposed within the first opening. The first strap includes a first proximal end attached to the first body, a first distal end opposite the first proximal end, and a plurality of first movement restriction members disposed along a surface of the first strap. The strap tie assembly also includes a second strap tie including a second base, a second body, and a second strap extending from the second body. The second base is configured to be disposed adjacent to a second surface. The second body includes a second opening and a second engagement member disposed within the second opening. The second strap includes a second proximal end attached to the second body, a second distal end opposite the second proximal end, and a plurality of second movement restriction members disposed along a surface of the second strap. The first opening is configured to receive the second strap, and the first engagement member is configured to engage one of the plurality of second movement restriction members of the second strap to prevent translation of the second strap away from the first body. The second opening is configured to receive the first strap, and the second engagement member is configured to engage one of the plurality of first movement restriction members of the first strap to prevent translation of the first strap away from the second body.
