Claim Text:
1. A medical cutting instrument for cutting muscles and tendons, comprising: a shaft, a tool mounted on a distal end of the shaft, the tool comprising two jaw members, such that at least one moveable first jaw member is configured as a jaw member that can be moved with respect to one other second jaw member and on whose proximal end a handle is mounted, such that the at least one movable first jaw member and the handle operatively interact with one another by way of an actuation element mounted in the shaft, in such a way that the at least one movable first jaw member can be shifted by actuating the handle between a closed position and an opened position of the tool and such that the tool is configured for simultaneously severing and holding one end of the severed muscle/tendon tissue, at least on the at least one movable first jaw member a cutting edge is configured, wherein the cutting edge is mounted on a distal end of the at least one first movable jaw member oriented toward the other second jaw member and wherein mutually corresponding clamping surfaces are mounted on both first and second jaw members, and a guide for controlled insertion of the muscle/tendon tissue that is to be severed is configured at least in the other second jaw member, wherein the guide is configured as an arc-shaped recess formed on an outer lateral edge of the second jaw member and open toward the at least one movable first jaw member and being aligned transverse with respect to the cutting edge of the at least one movable first jaw member, and wherein the guide ensures that the muscle/tendon tissue that is to be severed is aligned correctly with the cutting edge and with the clamping surfaces.
