Abstract

Improvements in skin closure means including means for uniting and holding separable closure members and skin portions attached thereto accurately together and to prevent separation thereof by forces which might otherwise cause the united members to separate. The subject construction also includes means for accurately guiding an instrument such as a scalpel while making an incision and for aligning and holding the separated edges of a skin wound or incision together during healing in such a way as to minimize or prevent the formation of scar tissue. The subject closure means are easy to apply quickly and accurately even under adverse conditions such as in first-aid treatment during emergencies, under disaster and wartime conditions, in emergency wards, in field, forest and wilderness situations and also under more controlled conditions such as operating rooms and doctors'"'"' offices particularly as the final step in completing a skin closure.

8. The means defined in claim 7 wherein the flange means and the respective sheet portions are integrally connected.

9. The means defined in claim 7 wherein the elongated flange means have angularly related opposite side surfaces such that the portions of said surfaces adjacent to the sheet are closer together than other locations thereon.

10. The means defined in claim 7 wherein said sheet portions are formed of a transparent substance.

11. The means defined in claim 7 wherein means are provided to limit and control the depth of penetration of the cutting edge of the instrument, said means including the elongated flange means.

12. A surgical template and closure means comprising a sheet of plastic-like material characterized by being able to intimately conform to a body skin surface, said sheet having opposite surfaces, means forming an adhesive layer on one of said opposite surfaces, elongated track forming means on the other of said opposite surfaces of said sheet, said track being defined by similar connected flange portions shaped to form a groove extending therealong for receiving and guiding a cutting edge of a surgical instrument used for making an incision wherein the cutting edge severs the track forming means and the sheet at a location along the groove and enters the flesh, said track forming means after being severed having spaced opposed side surfaces, and means including a separate channel-shaped member of uniform cross-section along its length having wall portions adapted to engage and embrace the severed track forming means therealong to hold the severed portions and the adhesively attached skin portions together and in abutment.

13. The means defined in claim 12 wherein the elongated track forming means has angularly related opposite side surfaces such that the portions of said surfaces adjacent to the sheet are closer together than at other locations thereon.

14. The means defined in claim 12 wherein said sheet is formed of a transparent substance.

15. The means defined in claim 12 wherein means are provided to limit and control the depth of penetration of the surgical instrument, said means including the elongated track forming means.

16. Means to close skin separations during surgery comprising a sheet of relatively easily severable material, said sheet being selected to have a desired size and shape to accommodate the surgery to be performed and having opposed surfaces, an adhesive substance applied to one of said opposed surfaces for attaching the sheet to the skin at the location where surgery is to be performed, means on the opposite surface forming a track for guiding a surgical instrument during the making of an incision, said track forming means including an elongated strip of material attached to said opposite surface at an intermediate location thereon, said strip having an elongated groove formed therein for receiving the cutting edge portion of a surgical instrument which when pressed down to a desired depth and moved along the groove will sever the track forming means and the sheet and complete the surgical incision, and means cooperatively engageable with the severed portions of the track forming means when they are brought together into abutment at the conclusion of the surgery for holding the severed portions thereof and the severed portions of the sheet together, said means cooperatively engageable with the severed track forming means including a separate elongated channel shaped member of uniform cross-section along its length having side edge portions which engage the respective severed track forming portions to hold them together.

17. The means defined in claim 16 wherein the sheet is formed of a relatively transparent substance.

18. The means defined in claim 16 including means for holding and supporting the sheet in a relatively flat condition to facilitate the accurate positioning thereof before attaching it to the skin.

19. The means defined in claim 16 wherein the track forming means include an elongated member having angularly related opposite side surfaces located on opposite sides of the groove, said track forming means having a portion thereof adjacent to where it is attached to the sheet that is relatively narrower than other portions thereof.

20. The means to close skin separations defined in claim 16 wherein said elongated channel-shaped member is formed of a relatively stiff but somewhat flexible resilient material.
