Abstract
Abstract A surgical wound closure in which none of the closure elements contact the wound surface includes a pair of flexible and pliable plastic skeleton rods having facing surfaces connectable together by alternate buttons and sockets. The outer surfaces of the rods support a plurality of pins that extend outward and downward to a position below the lower surface of the interconnected rods and which then terminate in inward curved sharpened points for engaging the skin about 8 mm each side of the wound edges. Each pin is provided with a plastic coating which ends short of the curved point to serve as a stop to limit the insertion of the pin.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
147 words
A wound closure comprising: a pair of skeleton rods, each rod having a substantially planar inner surface, an outer surface opposite said inner surface, and a bottom surface; a plurality of pins connected to the outer surface of each of said pair of rods, each pin extending outward from said outer surface and downward to a predetermined position below the level of said bottom surface and thence in an inward turning bend toward the wound to terminate in a short sharpened point for engaging the skin of a patient, each pin of said plurality being coated with a plastic coating between its respective skeleton rod and a predetermined position below the level of said bottom surface, said predetermined position forming a stop for limiting the length of insertion of said sharpened pin points; and means for interconnecting said planar inner surfaces of said pair of skeleton rods.
Claim 2
Dependent Claim
147 words
A wound closure comprising: a pair of skeleton rods, each rod having a substantially planar inner surface, an outer surface opposite said inner surface, and a bottom surface; a plurality of pins connected to the outer surface of each of said pair of rods, each pin extending outward from said outer surface and downward to a predetermined position below the level of said bottom surface and thence in an inward turning bend toward the wound to terminate in a short sharpened point for engaging the skin of a patient, each pin of said plurality being coated with a plastic coating between its respective skeleton rod and a predetermined position below the level of said bottom surface, said predetermined position forming a stop for limiting the length of insertion of said sharpened pin points; and means for interconnecting said planar inner surfaces of said pair of skeleton rods.
Claim 3
Dependent Claim
23 words
The closure claimed in claim 1 wherein each of said pair of skeleton rods are formed of a flexible and pliable plastic material.
Claim 4
Dependent Claim

Claim 5
Dependent Claim
35 words
The closure claimed in claim 1 wherein said plurality of pins are formed in pairs with each pair having an interconnecting section attached to the outer surface of each of said pair of skeleton bars.
