Abstract
This invention relates to an automatic instrument for purse-string sutures for surgical use, comprising two toothed jaws provided with openings having side slots for through passage of the needles carrying the ends of a suture thread fastened thereto. Said jaws are integral with a pair of support members adapted to be opened in order to be able to introduce the part to be sutured therebetween. Said support members carry a pair of flexible wires having one end wound around a pair of coaxial drums controlled by means of a knob, while the opposite ends are each connected to a needle, in such a way that by actuating the knob, the flexible wires unwind from the drums and push the needles through the jaw openings all the way to make the needle ends to project out of the ends of the jaws.
