Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
121 words
Hysterectomium in form of a multi-purpose instrument with clamping jaws and a locking device for stopping the clamping jaws in a clamping position, characterized in that a stitching device is provided at one side of the clamping jaws for stitching clamped parts of tissue over a section of the length of the clamping jaws and in that at the other side of the clamping jaws a mobile cutting blade is provided which is movable from an ineffective open position at a side of one clamping jaw to a region of a counter cutting edge at the other clamping jaw for cutting tissue over a section of the length of the clamping jaws at the said other side of the clamping jaws.
Claim 2
Dependent Claim
