Set of medical instruments for placing and shifting knots during surgery
First Claim
1. A set of medical instruments for shifting and placing knots produced by surgical sutures during operations, comprising a cylindrical rod displaceable lengthwise in a cylindrical sleeve, said rod projecting at both ends beyond said sleeve, with said rod having a head end that can be retracted into said sleeve and a handle that can be struck externally at the other end of said sleeve, and said head end of said rod is designed as a knot shifter for shifting and securing a knot produced by means of a suture, and said sleeve end into which said rod can be pulled is designed as a knot cutter with a cutting edge in order to separate suture ends from knots, wherein said rod is designed as a knot shifter with a convexly rounded head end and with two continuous bores extending from the head end to accommodate a suture to a cylindrical jacket surface of the rod and wherein an additional through bore for pulling a suture through is provided in a vicinity of the head end of the rod, said through bore being located transversely with respect to a lengthwise axis of the rod.

Abstract
A set of medical instruments for placing and shifting knots produced with surgical sutures during surgery, wherein a further through bore is provided for pulling a suture through in the vicinity of the head end of the rod, said bore being located transversely with respect to the lengthwise axis of the cylindrical rod, with the head end of the cylindrical rod being designed as a knot shifter for shifting and tightening a knot produced by means of the sutures. Using the knot shifter and knot cutter proposed according to the invention, a reliable knotting and hence immobilization of the parts rejoined by surgical sutures, such as tendons, to their original fastening areas can be achieved.
