Purse-stringer
First Claim
1. An instrument to facilitate the emplacement of a purse-string suture in a tubular structure, comprising a barrette-like structure having upper and lower jaws hinged together at one end, said jaws having longitudinally spaced clamping teeth with each of the teeth on said upper jaw being directly opposed to a corresponding tooth on said lower jaw whereby when a tubular structure is clamped between said jaws, the portions thereof between the pairs of opposing clamping teeth bulge out into the spaces between the teeth, a needle track extending longitudinally in each of said jaws disposed respectively above and below the clamping line of said teeth, whereby a needle and suture, in passing through the track of one of said jaws passes the suture through the portions of said tubular structure bulging into the spaces between the teeth on said one of said jaws, and in passing back through the track on the other of said jaws passes the suture through the portions of said tubular structure bulging into the spaces between the teeth on said other jaw, the tracks in the respective jaws communicating with each other, so that, when said jaws are unlatched and opened, said tubular structure, with the purse-string suture in place, may be removed from the instrument.

Abstract
A device for emplacing a purse-string suture in a severed end of a colon or other tubular structure. The device is generally barrette-like and has teeth on the upper and lower jaws which are mutually opposed so as to compress the tissue placed between the jaws and to permit tissue to bulge out into spaces between the respective teeth. Each jaw is provided with a needle guide or track through which a straight needle and suture may be passed and in passing through the needle track it will pass through the bulged out portions of the tissue. To emplace a purse-string suture, the needle is passed through one of the jaws in one direction and then looped around and passed through the other jaw in the opposite direction. A cutting guide is provided for severing excess tissue to provide a suitable cuff.
