DEVICE AND METHOD FOR FIXATING A SUTURE ANCHOR IN HARD TISSUE

摘要

The tool (1) for fixating a suture anchor (2) in a hard tissue opening with the aid of a material having thermoplastic properties and energy transmitted to the suture anchor for in situ liquefaction of at least part of the material having thermoplastic properties, comprises a distal face (10), an axial channel (11) and a substantially tube- shaped interface piece (3) fitting into the axial channel (11) of the tool (1), wherein the axial channel (11) and a proximal end of the interface piece (3) are equipped with catch elements (12 and 12') cooperating for catching the interface piece (3) in the axial channel (11) when the interface piece (3) is moved in a proximal direction in the axial channel (11). The suture anchor (2) is coupled to the distal end of the interface piece (3) and comprises an anchor foot (22), through which the suture (4) is threaded in form of a loop, and a thermoplastic sleeve (23).
