This disclosure relates to suture packaging devices and methods for packing sutures. More particularly, this disclosure relates to tray carriers and methods for packaging sutures in tray carriers.
Wound closure devices such as sutures, staples, and tacks have been widely used in surgical procedures in humans and animals for closing wounds, repairing traumatic injuries or defects, joining tissues together, attaching foreign elements to tissues, repositioning tissues to new anatomical locations, and a myriad of other purposes.
Sutures are also often used as wound closure devices. Sutures typically consist of a filamentous suture thread attached to one or more needles having a sharp point. Suture threads can be made from a wide variety of materials including bioabsorbable (i.e., that break down completely in the body over time), or non-absorbable (permanent; non-degradable) materials. Absorbable sutures have been found to be particularly useful in situations where suture removal might jeopardize the repair, or where the natural healing process renders the support provided by the suture material unnecessary after wound healing has been completed; as in, for example, completing an uncomplicated skin closure. Non-degradable (non-absorbable) sutures are used in wounds where healing may be expected to be protracted or where the suture material is needed to provide physical support for long periods of time; as in, for example, deep tissue repairs, high tension wounds, many orthopedic repairs and some types of surgical anastomosis.
Like any long flexible filament, sutures may tangle during removal from their packaging, when preparing them for use, or during use. Because of the tendency for long flexible filaments to tangle, manufacturers and medical practitioners use great caution to prevent tangling during the packaging process and during use of sutures. The handling of sutures and their attached needles also complicates the packaging and use of sutures.
Improperly packaged sutures may place the needles in a position where it is more likely to cause harm to medical practitioners, and some packaging device designs and methods for packaging may place the needles in less secure or less safe positions.
Suture packages, and in particular plastic tray suture carriers have only one path in which to wrap a suture. The single path typically restricts suture wrapping into circular or elliptical patterns and can inhibit the use of sutures other than simple geometry sutures with a single needle attached to a single straight thread.
Sutures, particularly sutures with synthetic thread may have a straight set in which the thread, when bent or wrapped, tends to unwrap and spring back towards a straight state. The thread set may cause sutures to prematurely unwind or tangle during wrapping on, transport in, and removal from a suture package.
Embodiments described herein provide a packaging device that may safely and securely hold a suture and its needles and provides for its easy and safe removal and a suture carrier that may retain the suture thread and resist its tendency to unwrap. In addition the embodiments describe safe, easy, and efficient methods for loading and removing sutures from their packaging.
The present disclosure is directed towards an apparatus for holding a suture. The apparatus may comprise a carrier including a base. The carrier may be configured to retain a cover over the base. The base may be configured to mount the carrier on a fixture and include a primary wrapping path disposed thereon, the wrapping path for wrapping at least a portion of a suture thread. The apparatus may include a plurality of suture retaining canopies located at an outer portion of the primary wrapping path and projecting from the base. The suture retaining canopies may be configured to facilitate retaining a suture thread within the primary suture path. The apparatus may also include a needle retainer disposed on the base. The needle retainer may include at least one slot configured to retain a needle.
The present disclosure is also directed to a method of using a suture carrier. The method may include loading a suture carrier onto a fixture by aligning one or more fixture apertures with a corresponding one or more fixture pins and lowering the suture carrier onto the wrapping fixture, wrapping a first suture thread into a first loop and placing the first suture thread on a base of the suture carrier, positioning at least a portion of the first loop of the first suture thread under a suture canopy, installing a cover over the first suture and the suture carrier, and engaging the cover with at least a portion of the suture carrier.
In the following description, certain specific details are set forth in order to provide a thorough understanding of various embodiments of the invention. However, one skilled in the art will understand that the invention may be practiced without these details. In other instances, well-known structures and steps associated with suture carriers and packaging have not been shown or described in detail to avoid unnecessarily obscuring descriptions of the embodiment of the invention.
The suture carrier 100 may also include carrier holes 180 to facilitate retaining the suture carrier 100 on a wrapping fixture, for example a wrapping fixture as shown in
One use of a suture carrier 100 may be to securely and safely store a suture needle and thread and provide a medical practitioner with easy and safe removal of a suture. The needle retainer 170 is adapted to hold one or more suture needles. For example, the illustrated needle retainer 170 includes two slots 171. Each slot 171 may hold one or more needles.
In some embodiments, a slot 171 may retain multiple needles stacked one on top of another or side-by-side within a single slot. Although depicted as having two slots 171, the needle retainer 170 may include a single slot or more than two slots. In some embodiments, the needle retainer may not have any slots and may retain suture needles using other structures. In some embodiments, a needle retainer may be adapted to hold large or small needles in correspondingly wide or narrow slots.
Although the illustrated suture carrier 100 includes a single needle retainer 170, a suture carrier may include more than one needle retainer. In some embodiments, a needle retainer may not be necessary, in which case, the suture carrier may not have a needle retainer. Moreover, although the needle retainer 170 is shown in the upper right-hand corner of suture carrier 100 and outside the outer perimeter of the wrapping paths 110, 120, as shown in
A suture carrier may include needle walls, for example, the suture carrier 100 includes two needle walls 178. The needle walls 178 can help separate the suture needles from the suture thread and thereby reduce the risk of sharp needles damaging the suture thread and, therefore, they may be located near the needle retainer 170. For example, the illustrated suture carrier 100 includes two needle walls 178 on opposing sides of the needle retainer 170.
The needle walls 178 may be integrated into the suture carrier 100. As shown in
In some embodiments, the needle walls 178 are separate from the base 101 and may be adhered or otherwise coupled to the base 101 during the manufacturing process.
Although the needle walls 178 are shown as substantially straight formations on the carrier base, the needle walls 178 may be curved or may have multiple sections, wherein one or more sections are straight and one or more sections are curved. The opposing surfaces 179, 177 of the needle walls 178 may be substantially planar and parallel to one another and they may extend substantially perpendicular to the base 101. In some embodiments, the surfaces 179, 177 may not be parallel to each other. For example, a bottom portion of the surfaces 179, 177 at or near the base 101 may be further away from each other as compared to a top portion of the surfaces 179, 177 at a distance from the base 101.
The suture carrier 100 may also include the carrier walls 130, 140, 150. The carrier walls 130, 140, 150 may define wrapping paths in the suture carrier 100. For example, the outer carrier walls 150 and intermediate carrier walls 140 can define a primary wrapping path 110 while the intermediate carrier walls 140 and inner carrier walls 130 can define a secondary wrapping path 120. The outer carrier walls 150 may define an outer boundary of the primary wrapping path 110 while the intermediate carrier walls 140 may define an inner boundary of the primary wrapping path 110.
The carrier walls 130, 140, 150 may include multiple surfaces 151, 152, 153. The surfaces 151, 152, 153 may include, for example, an outward facing surface 151, an inward facing surface 152 and a top surface 153. The surfaces 151, 152 of the carrier walls may be substantially planar and parallel to one another and they may extend substantially perpendicular to the base 101. In some embodiments, the surfaces 151, 152 may not be parallel to each other. For example, a bottom portion of the surfaces 151, 152 at or near the base 101 may be further away from each other as compared to a top portion of the surfaces 151, 152 at a distance from the base 101.
The embodiment shown in
The suture carrier 100 may also include one or more suture retention canopies 160. A suture retention canopy may be adapted or configured to retain a suture thread, in particular to retain a suture thread within a corresponding suture path. As shown in
The suture retention canopies 160 may be adapted to include a ceiling or retaining wall 161 that extend towards or into the suture wrapping path associated with the carrier wall the canopy is attached to, for example, the retaining wall 161. Thus, the suture retention canopies 160 may extend from the outer carrier wall 150 into or over the primary suture wrapping path 110.
As shown in
The suture carrier 100 may also include carrier holes 180. In some embodiments, for example as shown in
Although depicted on the outer carrier walls 150 along the primary wrapping path 110, the suture retention canopies 160 may facilitate retaining suture thread within other thread wrapping paths, for example the secondary wrapping path 120, and may extend from other carrier walls 130, 140.
Although shown as part of the carrier walls 150, the suture retention canopies 160 may be independent of carrier walls. For example, a suture carrier 100 may include suture retention canopies 160 at locations between the carrier walls, for example, between one or more outer carrier walls 150 or between opposing carrier walls, for example, between the outer carrier walls 150 and the intermediate carrier walls 140.
In some embodiments, the suture retention canopy 160 may extend directly from the base 101 or other structure of the suture carrier 100. In such embodiments, a retaining canopy may be formed by slitting or cutting through the base 101 and folding a portion of the base 101 in an upward direction, out of the page as shown in
Although the suture canopy retaining walls 161 are shown as parallel to the base 101, in some embodiments, a canopy may not be parallel to a base. For example, a retaining canopy or canopy retaining wall formed by slitting or cutting through a base and then folding a portion of the base in an upward direction may extend from the base at an angle less than 90 degrees or less than perpendicular to the base.
The carrier walls 130, 140, 150 may be integrated into the suture carrier 100. As shown in
In some embodiments, the carrier walls 130, 140, 150 are separate from the base 101 and may be adhered or otherwise coupled to the base 101 during the manufacturing process.
Although the carrier walls 130, 140, 150 are shown as substantially straight formations on the carrier base, the carrier walls 130, 140, 150 may be curved or may have multiple sections, wherein one or more sections are straight and one or more sections are curved. The surfaces 151, 152 of the carrier walls 130, 140, 150 may be substantially planar and parallel to one another and they may extend substantially perpendicular to the base 101. In some embodiments, the surfaces 151, 152 may not be parallel to each other. For example, a bottom portion of the surfaces 151, 152 at or near the base 101 may be further away from each other as compared to a top portion of the surfaces 151, 152 at a distance from the base 101.
In some embodiments, the carrier walls 130, 140, 150 may include a single surface 151, 152. In such embodiments, a surface may be formed by slitting or cutting through the base 101 and folding a portion of the base 101 in an upward direction, out of the page as shown in
The suture carrier 100 may include a base 101, which may include one or more carrier holes 180. The carrier holes 180 may be apertures cut, punched, or otherwise formed through the base 101. The carrier holes 180 allow one or more fixture pins, such as fixture pins 330, shown in
Although the embodiment shown in
Fixture pins may facilitate wrapping a suture thread and packaging it in the suture carrier 100. For example, up to eight fixture pins may be inserted through the eight carrier holes 180. An operator may then wrap a portion of a suture thread around the fixture pins. An operator could then place the portion of the suture thread wrapping around the fixture pins into the primary wrapping path.
In some embodiments, fixture pins are not used as a guide for wrapping suture thread. For example, an operator may wrap a portion of suture thread within the secondary wrapping path 120 without the use of fixture pins.
In some embodiments, a first portion of one or more suture threads may be wrapped and placed within the primary wrapping path 110 while a second portion of the one or more suture threads may be wrapped and placed within the secondary wrapping path 120. In some embodiments, a first suture thread may be wrapped in the primary wrapping path 110 while a second suture thread may be wrapped in the secondary wrapping path 120.
The suture carrier 100 may include a perimeter wall 104 around the perimeter of the suture carrier 100. The perimeter wall 104 may project upwards and out from the base of the suture carrier 100. The perimeter wall 104, may extend completely or partially around the perimeter of the suture carrier 100. For example, the illustrated suture carrier 100 includes a cutout 195 that interrupts the perimeter wall 104. In some embodiments, the suture carrier 100 may include a cutout 195 that does not interrupt the perimeter wall 104. For example, the perimeter wall may continue along an edge of the cutout 195.
The suture carrier 100 may also include cover tabs 190. The cover tabs 190 may extend out from the perimeter wall 104 such that they overhang the interior of the suture carrier 100. The cover tabs 190 are configured such that a perimeter of a suture cover, for example, a perimeter 204 of the suture cover 200 in
Although the cover tabs 190 of suture carrier 100 extend from the perimeter wall 104, in some embodiments, cover tabs may be independent of a perimeter wall. For example, the cover tabs may extend directly from the perimeter of a suture carrier.
The perimeter wall 104 adds depth to the suture carrier 100 and may have a height greater than the height of the carrier walls 130, 140, 150, and the needle retainer 170. The height of the perimeter wall 104 may be selected such that it is greater than the combined height of the carrier walls 130, 140, 150, the thickness of the suture carrier cover 200, and the thickness of the cover tabs.
In some embodiments, the distance between the base of the suture carrier 100 and the underside of the cover tabs 190 is about the same height as the carrier walls 130, 140, 150 or the needle retainer 170. In some embodiments, the distance between the base of the suture carrier 100 and the underside of the cover tabs 190 is about the same height as the combined height of the carrier walls 130, 140, 150 or the needle retainer 170 and the thickness of the suture carrier cover 200.
In some embodiments, the location or height of the cover tabs may be such that when a suture carrier cover 200 engages with an underside of the cover tabs 190, the suture carrier cover 200 contacts the top of one or more carrier walls 130, 140, 150 or needle retainers 170. This may cause bending in the suture carrier cover 200, which may reduce the suture carrier cover's movement after installation, and may facilitate a more positive hold on the suture carrier cover. A more positive hold may help prevent the carrier cover 200 from disengaging with the cover tabs 190.
In some embodiments, the location or height of the cover tabs may be such that an installed suture carrier cover 200 is only loosely engaged between the underside of the cover tabs 190 and the tops of the carrier walls 130, 140, 150, or the needle retainer 170.
Returning now to the suture carrier cutout 195, the suture carrier cutout 195 may provide access to the underside of an installed suture carrier cover 200. For example, in removing a suture carrier cover 200, the suture carrier cutout 195 may provide space for a practitioner to place their fingers such that the practitioner may grasp the suture carrier cover 200 from the underneath as well as from above. In this way, the practitioner may grab suture carrier cover 200, disengage it from the cover tabs 190, and remove the suture carrier cover 200 from the suture carrier 100. In some embodiments, the suture carrier 100 may include more than one suture carrier cutout 195.
As shown in
The suture carrier 100 may also include a location for product information, for example, a recess 102 which is sized and shaped to receive a product information label.
The suture carrier cover 200 may include wrapping fixture apertures, such as retention and alignment cover apertures 210. The cover apertures 210 may be cut, punched, or otherwise formed through the cover 200. The cover apertures 210 allow one or more fixture pins, such as fixture pins 330, shown in
Although the embodiment shown in
The cover 200 may also include a perimeter 204. The perimeter 204 may be sized and shaped to correspond with a perimeter of a suture carrier, for example, the perimeter 104 of the suture carrier 100 shown in
The cover 200 may also include through slits 220. The through slits 220 may be positioned along or around the perimeter 204 of the cover 200. The through slits 220 may be cuts through the cover 200. The cut may start at an edge or perimeter 204 of the cover 200 and may extend towards the interior of the cover 200. In some embodiments, the through slits 220 may be perpendicular to an edge or perimeter of the cover 200.
The through slits 220 may create weak points in the cover 200. The location of the through slits 220 may correspond with one or more locations of cover tabs 190 of a suture carrier 100. By weakening the cover in locations that correspond to cover tabs, the through slits may facilitate easier installation of the cover 200 onto a suture carrier 100.
The suture carrier cover 200 may also include a cutout 230, to provide access to the recess 102 of the suture carrier 100. For example, the cutout 230 may permit a user to view a label or other information printed in the recess 102.
The mounting post 320 includes one or more indexes or flats 322 for coupling a wrapping fixture 300 to a fixture holder, not shown, or to the base 350. The flats may interface with the fixture holder to aid in preventing the wrapping fixture 300 from rotating while coupled to or held by the fixture holder.
The first coupler 342 may couple the mounting plate 310 to the mounting post 320. The first coupler 342 may pass through an aperture 340 in mounting plate 310 and into a hole 324 in mounting post 320. The vertical hole 324 may be a blind and threaded hole as shown in
The second coupler 360 may couple the base 350 to the mounting post 320. The second coupler 360 may pass through an aperture 352 in base 350 and into a hole 326 in mounting post 320. The hole 326 may be a blind and threaded hole as shown in
The mounting plate 310 may also include apertures 332 configured to receive pins 330. Pins 330 are configured and/or adapted to receive a suture carrier and a cover, such as carrier 100 of
The mounting plate 310 may also include one or more bevels 312. When a suture carrier is placed on the fixture 300, the bevels 312 in the plate 310 create a space between the underside of a suture carrier and the mounting plate 310, which may allow a user to grip or otherwise handle the bottom of a suture carrier. This may facilitate handling a suture carrier, and in particular removing a suture carrier from the wrapping fixture 300.
