A lever (20) for grasping bone tissue includes a shaft (30) defining a channel (32) and having a proximal end and a distal end, a claw member (50) disposed on the distal end of the shaft for holding the bone tissue, and a rod (60) threadably received in the channel (32) and having a proximal end and a distal end. Rotation of the rod with respect to the shaft causes the rod to move substantially axially with respect to the shaft to selectively position the distal end of the rod with respect to the claw member. The lever (20) may further include a locking member to allow the rod to slide axially with respect to the shaft. Various other features which improve the functioning of the lever may be provided separately or in combination.

La rotation de la tige par rapport au manche fait se d~placer ladite tige sensiblement axialement par rapport au manche, ce qui permet de positionner l'extr~mit~ distale de la tige par rapport ~ l'~l~ment de griffe. De plus, le levier peut Útre muni d'un ~l~ment de blocage qui permet ~ la tige de coulisser axialement par rapport au manche.
