ABSTRACT:
A suture tensioning apparatus for tightening the suture used to tie a tissue of a patient to the bone of the patient so that the tissue will cinch to the bone. A lever is mounted on a stub shaft that is supported to a base member and is movable in a lateral position. A pair of spaced spools are mounted on the lever and the reach of the suture is wrapped around each of the spools. Means, including a coil spring wrapped around the stub shaft is connected to the lever and a rotatable dome. The movement of the lever causes the lower portion of the coils to unwrap around the stub shaft, and rotation of the dome causes the upper portion of the coils to unwrap whereby the movement of the coil spring forces the lever to return to its original position. The tensioning apparatus can be incorporated into an existing suture gun or can be made integral therewith.
