The suture clip includes a pair of plates joined together at one end to form a vertex having an acute angle. Each plate, at its remote terminal end, defines an inwardly facing hook. The hook end members establish a clip mouth slightly larger than the diameter of the suture thread such that when the thread is passed through the clip mouth, the thread cannot easily escape entrapment from the central region of the clip. The suture clip may be C-shape, V-shape, broken leg V-shape, heart shape or pentagonal shape. In another embodiment, the clip is a closed loop or elliptical in shape. To enhance operability, the hooks on the C, U or V shaped sutures are disposed on tabs which are laterally displaced with respect to each other such that, upon collapse and closure of the clip plates, the tabs interleave each other and interlock over the opposite clip plate. This feature enhances attachment to suture thread. The method for attachment on suture thread includes providing a clip having several specific features, passing the suture thread through the clip mouth and collapsing the clip plates together over the suture. The enhanced method interleaves terminal edge tabs and interlocks a respective tab over an opposing corresponding clip plate. The surgical appliance for clipping together suture thread includes a suture clip having certain characteristics, a pair of opposing appliance jaws and an elongated mechanical linkage which, upon compression of handle members by a user at a proximal location, the mechanical linkage transfers that force and movement to the compress appliance jaws at a distal end of the appliance thereby closing the suture clip on the suture thread. The enhance threading the suture through the lumen of the clip, an elongated closed loop wire is utilized. |
