Abstract: A surgical punching instrument is provided with a fixed handle (14) attached to a punching bar (2) and with an actuating lever (16), which is mounted thereon in a pivotingly movable manner and which is connected via a short lever arm (17) to a punching slide (1), which is in turn under the action of a restoring spring (23). The punching slide (1) lies with its flat sliding surface (3) on a flat guiding surface (4) of the punching bar (2) over its entire length and is guided at same in an axially movable manner by means of guide elements (5 through 8), which have a T-shaped profile, engage one another in a positive-locking manner and are detachable by longitudinal displacement.

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.
