Abstract
The invention relates to a rongeur-type surgical instrument comprising a fixed handle (2) which receives an elastically-loaded movable handle (4) around an axis of rotation (5), a fixed clamping jaw (3), one end of which is solidly connected to a cutting jaw, (25) and a movable clamping jaw (6). The movable clamping jaw moves in translation on the fixed clamping jaw (3) when the movable handle (4) pivots around the axis of rotation (5) in such a way that the sharp edges (45) of the free end thereof co-operate with the sharp edges (27) of the fixed clamping jaw (3). Said movable clamping jaw (6) comprises an internal channel (44) which stores the fragments of cut bone tissue (56), while the fixed clamping jaw (3) comprises transfer means (30) which co-operate with the movable clamping jaw (6) in order to enable the fragments of cut bone tissue (56) to penetrate a space (41) in the movable clamping jaw (6) which is disposed in the extension of the channel (44).
