Patent ID: 7662167

Claim:
A medical instrument with a hollow shaft extending along a longitudinal axis, said hollow shaft having at its proximal end a handle consisting of at least two gripping members and at its distal end a tool consisting of at least two jaw members, where at least one of the jaw members of the tool can rotate in relation to the at least one other jaw member of the tool for purposes of opening and closing by means of one rotatably designed gripping member of the handle, and wherein the at least one rotatable jaw member and the gripping member of the handle that serves to rotate the at least one jaw member are connected to one another by means of a push pin stored in the hollow shaft and the push pin can be displaced exclusively in the axial direction by means of the corresponding at least one rotatable gripping member of the handle, wherein at least one of the jaw members is directly mounted to the distal end of the hollow shaft, wherein at least a portion of the push pin is inside, at least partly in form-locking connection, a rigid casing extending along the longitudinal axis, which in turn is inside, at least partly in form-locking connection, the hollow shaft, and wherein the form-locking connection of the push pin and the rigid casing secures the push pin against rotation relative to said rigid casing about the longitudinal axis at least in some sections in the casing.
