Abstract
A surgical laparoscopic apparatus comprises a protector tube (11) and a hgrip (12) mounted onto the rear end thereof. At least one rod-shaped instrument (13) is arranged in an axially removable way in an axial guide channel (14) provided in the protector tube (11) and the handgrip (12). A dual purpose flushing/suction channel (15) extends parallel thereto in the protector tube (11) and partially also in the handgrip (12) and passes through the handgrip (12) to external flush and suction connectors (16, 17). A twin-position three-way valve (19) is arranged in the handgrip adjacent to the guide channel (14) and, in the one position, connects the flushing/suction channel (15) to the flush and suction connectors (16, 17) and, in the other position, connects the guide channel (14) to the flush connector or suction connector (16, 17).
