Abstract
Abstract A device to facilitate accurate placing of sutures for closing a wound or incision which takes the form of an elongated wire member the ends of which are to be located at the ends of the wound or incision. The device is to be resilient forcing outwardly the ends of the device and thereby making the wound or incision taut. The side walls of the wound or incision are maintained in accurate apposition so as to facilitate the location of the sutures.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
258 words
A skin retractor for use during suturing of an incision comprising: an elongated narrow body having a first end and a second end; a first connecting end attached to said first end, said first connecting end including a first member extending substantially at a right angle from said body a second member extending substantially at a right angle from said first member; a second connecting end attached to said second end, said second connecting end including a third member extending substantially at a right angle from said body and a fourth member extending substantially at a right angle from said third member; said first end and said second end to be located at opposite ends of the surgical incision causing slight stretching of the incision resulting in the incision side walls being stretched taut to maintain accurate apposition of the incision side walls to facilitate satisfactory closing of the incision and subsequently the most desirable incision scar in appearance; a fifth member connected to and extending substantially at a right angle from said second member, said fifth member being positioned substantially perpendicular to said body; a sixth member extending from and being connected to at substantially a right angle from said fourth member, said sixth member being positioned substantially parallel to said fifth member; and a seventh member connected to and extending angularly outwardly from said fifth member, an eighth member connected to and extending angularly outwardly from said sixth member, in respect to said body the said seventh and eighth members extend in substantially the same direction.
Claim 2
Dependent Claim
