ABSTRACT:
A method and apparatus for tightening of knots formed at a remote location in the body through the endoscopic surgical technique utilizing a knot pusher (10) having a cylindrical end face with diametrically opposed suture guide notches (16) formed on such end face (14). The knot pusher (10) defines an elongated groove (12) for reception of the elongated body portion (22) of a knot clamping instrument (20). The application of a pulling force (T) to the knot after it has been positioned adjacent the body parts results in the knot being tightened by forces which are generally radial to the axis of the knot pusher (10). The knot clamping instrument (20) is utilized to secure a previously formed knot while a second knot is formed in the ends of the suture and moved into position by the knot pusher (10).
