Arthroscopic instrument with suction tube

Abstract

Abstract 1. Arthroscopic instrument including a suction tube (10) which at its front end has a jaw part (12) which includes a cutting blade (18) and a die part (20) cooperating with it and pivotally connected to the jaw part (12) and which at its rear end is connected to an actuating device (14) which includes a first handle member (28) rigidly mounted on the suction tube (10) and a second handle member (32) which is movable with respect to the suction tube, and including an actuating rod (22) which is longitudinally movably and eccentrically mounted in the suction tube (10) adjacent its inner wall and which couples the movable die part (20) to the movable handle member (32) and has an external diameter which is substantially smaller than the internal diameter of the suction tube so that a suction passage (26), which is provided with a connecting member (16) adjacent the actuating device (14), remains clear within the suction tube, characterised in that the actuating rod (22) is retained at the inner wall of the suction tube (10) by a number of spaced retaining claws (24) which have the shape of circular segments, fitting into the suction tube (10) with a hole for the actuating rod (22), extend radially into the interior of the suction tube (10) at most as far as the actuating rod (22) and have bevelled axial ends (24, Fig. 2).
