摘要

The rinsing pipe (4) connected to the rinsing canula (9) which is inserted into the suction canula (3) runs inside the suction pipe (2). The rinsing pipe and suction pipe are concentric. The end of the rinsing pipe furthest from the rinsing canula is radially held by the rinsing canula running through the suction canula, and slides through a guide head (10) fixed to the end of the suction pipe. The guide head has a fixture for locking the rinsing pipe in position.
