SURGICAL POSITIONING AID

BACKGROUND

The present disclosure relates to a positioning aid, for supporting a patient during surgery. More particularly, the present disclosure relates to a support for positioning a portion of a patient's body during a surgery.

Often, when a patient is positioned for a surgery, the patient is supported by and secured to braces or supports coupled to a surgical table. Sometimes, positioning aids are inserted at the interface of the patient's body and the braces or supports to position a portion of the patient's body.

Positioning aids known in the art are often impromptu solutions provided by materials at hand at the time of a surgery or procedure. Aids such as pads, towels, or blocks can be difficult for caregivers to arrange and/or rearrange to position a patient as desired for surgery

SUMMARY

A positioning aid has one or more of the features recited in the appended claims and/or the following features which, alone or in any combination, may comprise patentable subject matter:

A surgical positioning aid for positioning a patient's wrist is disclosed. The surgical positioning aid may include a sheet of foldable material. The sheet of foldable material may be foldable between a flat position and a wrist support position. In the support position, the sheet may be folded to form a hump having sufficient strength to support a patient's wrist during surgery. The sheet may also have a coupler at a first end region of the sheet. The coupler may engage a second end region of the sheet to hold the sheet in the wrist support position. The second end region may be opposite the first end region.

In some embodiments, the sheet may be foldable to a recovery position in which the sheet is folded over itself in a substantially flat configuration. In some such embodiments, the sheet of foldable material may include a locking coupler and a locking coupler receiver. The locking coupler may engage the locking coupler receiver when the sheet of foldable material is folded to the recovery position.

It is contemplated that the foldable sheet may include at least one living hinge about which the sheet is folded. In such embodiments, the at least one living hinge may form an apex of the hump having sufficient strength to support a patient's wrist during surgery.

The coupler at the first end region of the sheet may include a coupler tab bendable out of alignment with the sheet. In such embodiments, the second end region may include a series of coupler tab receivers formed through the sheet and sized to receive the coupler tab. The coupler tab may be defined by a U-shaped slot formed through the sheet.

According to this disclosure, therefore, a surgical positioning aid may include a flat sheet of foldable material having a first, a second, and a third portion. The first portion may be separated from the second portion by a first living hinge. The third portion may be separated from the second portion by a second living hinge. The sheet may also have a tab. The first portion of the sheet may also have at least one slot to receive the tab. Such a sheet may be movable between a flat position prior to use in surgery and a support position for surgery. In the support position, the second portion may be folded relative to the first portion about the first living hinge and the third portion may be folded relative to the second portion about the second living hinge. Further, the tab may be received in the at least one slot of the first portion such that the first and the second portions cooperate to form a hump relative to the first portion.

It is contemplated that the hump may include an apex formed by the second living hinge and that the apex may be spaced above the first portion of the sheet. The second living hinge may include at least two series of perforations formed through the sheet providing a gradual bend when the first living hinge is folded.

In some embodiments, the second portion may form a ramp between the first living hinge and the first portion. The third portion may form a ramp between the second living hinge and the tab.

The sheet may further be movable to a recovery position wherein the second portion is folded over the first portion about the first living hinge such that the second portion overlies and is substantially parallel to the first portion. In such embodiments, the third portion may be folded relative to the second portion about the second living hinge such that the second and the third portions are substantially flat relative to one another. The second portion of the sheet may include a first locking tab and the first portion of the sheet may include a first locking tab receiver sized to receive the first locking tab. The first locking tab may be received by the first locking tab receiver when the surgical positioning aid is moved to the recovery position so that the locking tab blocks the second portion from unfolding relative to the first portion about the first living hinge.

The sheet may be formed to include at least one strap slot sized for a strap to extend through the at least one strap slot. In such embodiments, the second portion may be formed to include a first strap slot and the third portion may be formed to include a second strap slot.

The sheet may include a fourth portion separated from the third portion by a third living hinge. The fourth portion may be formed to include a U-shaped slot defining the tab. The fourth portion may be folded relative to the third portion about the third living hinge so that the fourth portion overlies and is substantially parallel to the first portion when the surgical positioning aid is moved to the support position.

According to this disclosure, therefore, a surgical positioning aid for radial artery catheterization may be designed to allow for a hemostatic cuff to be in place during the procedure and subsequently applied without the repositioning of the patient's limb.

It is contemplated that the cuff is inflatable. The cuff may be made from a flexible material and may act like a tourniquet.

In some embodiments, the surgical positioning aid may include a means for securing the aid to a fixed surface. The surgical positioning aid may be operable to support a patient's entire arm. The surgical positioning aid may be made from a semi-rigid foam. The surgical positioning aid may include a thin rigid portion.

It is therefore disclosed that a surgical positioning aid for radial artery catheterization may include an arm support portion and a curved portion operable to position a patient's wrist in a hyper-extended position.

The surgical positioning may be configured to couple to a surgical table. In some embodiments, the surgical positioning aid may be radiolucent. The arm support portion may include a coupler portion configured to extend between a section of a surgical table and a mattress so that the surgical positioning aid is coupled to a surgical table.

Additional features, which alone or in combination with any other feature(s), such as those listed above and those listed in the claims, may comprise patentable subject matter and will become apparent to those skilled in the art upon consideration of the following detailed description of various embodiments exemplifying the best mode of carrying out the embodiments as presently perceived.

DETAILED DESCRIPTION

An illustrative surgical positioning aid 10 used for positioning a patient's arm, hand, and wrist during and after trans-radial cardiac catheterizations is shown in FIG. 1. In other embodiments, the surgical positioning aid 10 may be scaled up or down in size for positioning other parts of a patient during other surgeries or operations including but not limited to: positioning a patient's knee relative to a patient's hip during hip surgery or positioning a patient's head relative to a patient's torso for tracheal tube placement.

The aid 10 is illustratively a sheet of plastics material and includes a base portion 12, an arm portion 14, a hand portion 16, and a tab portion 18. The base portion 12 is situated at a first edge 19 of the aid 10. The tab portion 18 is situated at a second edge 21 of the aid 10. The aid 10 is movable between a flat position for storage (as shown in FIG. 3), a support position for supporting a patient's arm, hand, and wrist, while the patient's wrist is in a hyper-extended position during trans-radial cardiac catheterizations (as shown in FIG. 1), and a recovery position for supporting a patient's arm, hand, and wrist during recovery from trans-radial cardiac catheterizations (as shown in FIG. 2).

The base portion 12 of the aid 10 is coupled to the arm portion 14 by a first living hinge 20 situated between the base portion 12 and the arm portion 14. The arm portion 14 of the aid 10 is coupled to the hand portion 16 by a second living hinge 22 situated between the arm portion 14 and the hand portion 16. The hand portion 16 of the aid 10 is coupled to the tab portion 18 by a third living hinge 24 situated between the hand portion 16 and the tab portion 18.

The first living hinge 20 is formed by a series of perforations 26 extending through the aid 10 arranged in a linear pattern between a top edge 27 and a bottom edge 29 of the aid 10. The first living hinge 20 is configured to provide sharp bend between the base portion 12 and the arm portion 14. In other embodiments, the first living hinge 20 may be formed by a thinned section of the aid 10 between the base portion 12 and the arm portion 14.

The second living hinge 22 is illustratively formed by a first series of perforations 28, a second series of perforations 30, and a third series of perforations 32 extending through the aid 10 and arranged in linear patterns between the top edge 27 and the bottom edge 29 of the aid 10. The second living hinge 22 is configured to provide gradual bend between the arm portion 14 and the hand portion 16. In other embodiments, the second living hinge 22 may be formed by a thinned section of the aid 10 between the arm portion 14 and the hand portion 16. In such embodiments, the thinned section of the second living hinge may extend a greater distance between the first edge 19 and the second edge 21 of the aid 10 than a thinned section forming the first living hinge.

The third living hinge 24 is formed by a series of perforations 34 extending through the aid 10 arranged in a linear pattern between the top edge 27 and the bottom edge 29 of the aid 10 as shown in FIG. 3. The third living hinge 24 is configured to provide a sharp bend between the hand portion 16 and the tab portion 18. In other embodiments, the third living hinge 24 may be formed by a thinned section of the aid 10 between the hand portion 16 and the tab portion 18.

The tab portion 18 of the aid 10 includes a coupler tab 36 for selectively securing the hand portion 16 to the base portion 12. The coupler tab 36 is defined by a U-shaped slot 38 formed through the aid 10. The coupler tab 36 is configured to be bent down from the aid 10 by a caregiver as shown in FIG. 4. In some embodiments, rather than the coupler tab 36, an adhesive, complementary patches of hook and loop material, or another securing arrangement may be used for selectively securing the hand portion 16 to the base portion 12.

The arm portion 14 of the aid 10 includes a first lock tab 37 and a second lock tab 39. The first lock tab 37 is formed along the top edge 27 of the aid 10. The second lock tab 39 is formed along the bottom edge 29 of the aid 10. The first and the second lock tabs 37, 39 are configured to be bent down from the aid 10 by a caregiver as shown in FIG. 9.

As shown in FIG. 3, the base portion 12 of the aid 10 includes a series of coupler tab receivers 40 extending through the aid 10 and sized to receive the coupler tab 36. The series of coupler tab receivers 40 includes coupler tab receivers 42, 44, 46, 48, 50. The base portion 12 also includes a first lock tab receiver 47 and a second lock tab receiver 49. The first lock tab receiver 47 is formed in the top edge 27 of the aid 10 and the second lock tab receiver 49 is formed in the bottom edge 29 of the aid 10. The first and the second lock tab receivers 47, 49 are sized to receive the first lock tab 37 and the second lock tab 39, respectively.

When the aid 10 is in the stored position, the aid 10 is substantially flat. Also, the base portion 12 is spaced apart from the tab portion 18. Further, neither the coupler tab 36 nor the first and the second lock tabs 37, 39 are bent down from the aid 10. Thus, the aid 10 is easily stored or stacked in the stored position.

To move the aid 10 from the stored position to the support position, the first living hinge 20 is bent so that the arm portion 14 extends over the base portion 12 forming an angle α between the base portion 12 and the arm portion 14. Thus, the base portion 12 and the arm portion 14 form a first ramp 51. Additionally, the second living hinge 22 is gradually bent so that the second living hinge 22 forms an apex 52 spaced above the base portion 12. Further, the hand portion 16 extends from the apex 52 to the base portion 12 so that the hand portion 16 extends over the base portion 12 forming an angle β between the base portion 12 and the hand portion 16. Thus, the base portion 12 and the hand portion 16 form a second ramp 54. Finally, the third living hinge 24 is bent so that the tab portion 18 overlies and is substantially parallel to the base portion 12. In some embodiments, additional straps may be wrapped around the base portion 12 and an arm board or other support to secure the aid 10 relative to an overall patient support. In other embodiments, the base portion 12 may include additional tabs that are operable to be bent down and secured to an arm board having slots to receive the additional tabs, thereby securing the aid relative to an overall patient support.

When the aid 10 is moved to the support position, the arm portion 14 is operable to support a patient's arm, the hand portion 16 is operable to support a patient's hand, and the second living hinge 22 is operable to support a patient's wrist in a hyper-extended position suitable for catheterization. Also, the coupler tab 36 is bent down from the tab portion 18 of the aid 10 and is inserted into one of coupler tab receivers 42, 44, 46, 48, 50 so that the positions of the arm portion 14 and the hand position 16 are maintained relative to the base portion 12.

In the support position, the angles α, β are adjustable depending on which coupler tab receiver 42, 44, 46, 48, 50 receives the coupler tab 36. Thus, a physician may adjust the angle at which a patient's wrist is hyper-extended among a series of angles as shown in FIGS. 6-8. The physician may adjust the angle of hyper-extension for a catheterization depending on physician preference, patient flexibility, and other factors. In some embodiments, while the aid 10 is in the support position, the angle of a patient's hyper-extended wrist may be between 35 and 65 degrees. In some embodiments an occlusion band may have an inflatable hemostatic cuff and the occlusion band may be passed between the base portion 12 and the overlying arm portion 14 for use before, after or during a catheterization. In some such embodiments, the occlusion band may be made from a flexible material and may act as a tourniquet.

To move the aid 10 from the support position to the recovery position, the first living hinge 20 is further bent so that the arm portion 14 overlies and is substantially parallel to the base portion 12. Additionally, the second living hinge 22 is unbent so that the hand portion 16 is flattened relative to the arm portion 14. Further, the hand portion 16 in the recovery position overlies and is substantially parallel to the base portion 12. In the recovery position, the angle α is about 180 degrees and the angle β is about 0 degrees. Thus, in the recovery position, a patient's wrist is moved away from the hyper-extended position.

When the aid 10 is moved to the recovery position, the arm portion 14 is operable to support a patient's arm, the hand portion 16 is operable to support a patient's hand, and the second living hinge 22 is operable to support a patient's wrist in a substantially flattened position suitable for recovery. Also, the coupler tab 36 is removed from the coupler tab receivers 42, 44, 46, 48, 50 and is moved back into alignment with the aid 10. Additionally, the lock tabs 37, 39 are bent down from the arm portion 14 and are inserted into the lock tab receivers 47, 49, respectively. When the lock tabs 37, 39 are inserted into the lock tab receivers 47, 49 the aid 10 is locked in the recovery position. The lock tabs 37, 39 are operable to move into and out of the lock tab receivers 47, 49 while a patient's arm, hand, and wrist are supported on the aid 10. Thus, the aid 10 is movable from the support position to the recovery position while a patient's arm, hand, and wrist remain supported on the aid 10. In some embodiments an occlusion band may have an inflatable hemostatic cuff and the band may be passed between the base portion 12 and the overlying arm portion 14 so that the occlusion band may be secured over a patient's arm to slow circulation to a catheter insertion point before, during or after a catheterization. In some such embodiments, the occlusion band may be made from a flexible material and may act as a tourniquet.

The arm portion 14 also includes a first arm strap slot 57, a second arm strap slot 59, and an arm strap 60. The first and the second arm strap slots 57, 59 extend through the aid 10 and are situated near the top and the bottom edges 27, 29 of the aid, respectively. The arm strap 60 extends through the first and the second arm strap slot 57, 59 and is operable to be wrapped around and secure a patient's arm to the arm portion 14 of the aid 10. In the illustrative embodiment, the arm strap 60 includes a hook material face 62 and a loop material face 64 so that the arm strap 60 can be secured to itself. In other embodiments, the arm strap 60 may include clasps, hooks, snaps or the like to secure a patient's arm to the arm portion 14 of the aid 10.

The hand portion 16 also includes a first hand strap slot 67, a second hand strap slot 69, and a hand strap 70. The first and the second hand strap slots 67, 69 extend through the aid 10 and are situated near the top and the bottom edges 27, 29 of the aid, respectively. The hand strap 70 extends through the first and the second hand strap slots 67, 69 and is operable to be wrapped around and secure a patient's hand to the hand portion 16 of the aid 10. In the illustrative embodiment, the hand strap 70 includes a hook material face 72 and a loop material face 74 so that the hand strap 70 can be secured to itself. In other embodiments, the hand strap 70 may include clasps, hooks, snaps or the like to secure a patient's hand to the hand portion 16 of the aid 10.
