ABSTRACT:
A surgical punching instrument with a fixed handle (21) is attached to a tubular guide part (20). An actuating lever (23) is mounted on the fixed handle (21) in a pivotingly movable manner and is in connection with a plunger (27) via a short lever arm (24). This plunger is in turn connected to a punching slide (1) and is mounted for actuating same against the action of a compression spring in an axially movable manner in a rearward mounting part (31) of a punching bar (2), which is guided rotatably by an at least partially cylindrical guide section (33, 34) and lockably in different rotated positions in the guide part (20). The punching bar is in contact in the guide part (20) with an axial stop acting in the direction of actuation with a ring shoulder (35) and it is locked in an axially detachable manner. The axial stop, with which the ring shoulder (35) is in contact, comprises a spring-loaded locking lever (37), which passes through a guide slot (45) of the guide part (20) radially into a cylindrical cavity (20′) of the guide part (20), in which the guide section (33, 34) of the mounting part (31) of the punching bar (2) is guided.
