ABSTRACT:
A suturing apparatus to suture tissue edges to each other includes an oscillating needle and a loop catcher cooperating with the needle to form stitches. Two-legged forceps are provided to brace the tissue edges in the vicinity of the needle path transverse to the tissue edges. The forceps are movable to a closed position for holding together the tissue edges before the needle pierces them and, upon the ensuing exit of the needle from the tissue edges, an opened position to release the tissue edges. Furthermore, advancing tongs with two legs are provided for gripping the tissue edges directly on the other side of the forceps in a closed position and, in an open position, to release the tissue edges. The tongs are also shifted during each open phase of the forceps during a movement of the tissue in an advancement direction from an initial position into a closed position and, during each closed phase of the forceps, to their open position in a direction opposite the direction of advancement and back into the initial position.
