The invention relates to a coupling for the releasable connection of a laparoscopic instrument working with movable parts with a grip for actuation of the instrument. The invention is to permit a coupling between the instrument and the grip which is of simple design, safe to handle, easily releasable and closeable. According to the invention, a first locking element (22) is provided at the proximal end of a push rod (20)guided in the instrument tube (10) and a second locking element (12) at the proximal end of the instrument tube (10). A first recess (42) is provided at the distal end of the adjustment elememnt (40) in the grip for the laterall insertion of the first locking element (22) and a second recess (32) at the distal end of the housing (3) for the second locking element (12). The housing (30) is opened so wide laterally in the zone of the coupling that the instrument tube (10) and the push rod (20) guided therein with their locking elements (12,22) are laterally insertable into the housing and the associated recesses. Through the insertion of the first locking element (22) into the first recess (42), the push rod (20) is couple to the adjustment element (40), and the insertion of the second locking element (12) into the second recess (32) secures the instrument tube (10) against axial movement with respect to the housing (30) of the grip. To close the second laterally opened zone of the housing (30) and secure the first and second locking elements in the recesses against lateral movement, a displaceable closing sleeve (5) is provided which can be pushed over the laterally opened zone of the housing (30). |
