ABSTRACT:
This invention relates to surgical instruments used, for example, in approximation of the sternum after median sternotomy. The device according to this invention is utilized to tighten applied sternal sutures, such as wires, by first winding up the sutures on a spool, then twisting the sutures for fixation and to provide an appropriate final tension. A cutting mechanism is included for severing the sutures so as to leave a short twisted segment, resulting in a joint secure against slippage. Waste sutures are stripped from the spool against a stripping plate by axial translation of the spool. A crank and sleeve may be included to facilitate twisting the sutures for fixation and final tensioning. An optional ratchet or similar mechanism may be used to prevent unwinding of the sutures from the spool during operation.
