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.
