METHOD AND DEVICE FOR THE ARTHROSCOPIC REATTACHMENT OF TORN TISSUES, IN PARTICULAR OF TORN ROTATOR SHEATHS

摘要

A method and device for the arthroscopic reattachment of torn tissue to a bone are described. The device for carrying out this method comprises at least one suture reinforcement (30) and a tissue grasping device (10). The torn tissue is grasped by the jaws (12) of the tissue grasping device (10). The jaws (12) comprise an upper jaw (44) having an opening and a lower jaw (42) having a U-shaped groove. The opening and the groove are aligned with one another when the jaws (42, 44) are closed. The suture reinforcement (30), provided with a thread, is introduced through the aligned opening and groove of the jaws (42, 44) of the tissue grasping device (10) into the bone by a single boring step when the tissue has been grasped. An extendible support foot (18), located on a sleeve (16) of the tissue grasping device (10), is used to accommodate a drill and to align the suture reinforcement (30) provided with the thread, so that the suture reinforcement is automatically aligned with the opening (48) and the groove (46) of the jaws (42, 44) at the operating site. The thread is drawn back by the upper jaw (44) of the tissue grasping device (10) when the latter is removed.
