Pincers attachment for a surgical handle to be used in endoscopy
First Claim
1. A pincers attachment for surgical handle to be used in an endoscope, said attachment comprising a hollow outer shaft of a constant diameter and a connecting rod axially displaceable in the outer shaft, said shaft and connecting rod being provided at their proximal ends with coupling parts, an axial position of the shaft relative to the coupling part being adjustable, said coupling parts being fastened respectively to two relatively displaceable parts of a surgical handle, said shaft near a distal end being provided with a solid portion with a laterally opening recess for receiving clip means having compressible legs, said solid portion having a longitudinal bore opening into the recess, a closing rod being received in said longitudinal bore and being connected to the distal end of the connecting rod so that when the displaceable parts are moved, said connecting rod urges a distal end of the closing rod into engagement with a leg of a clip means disposed in said recess to compress the legs of the clip means together.

Abstract
A pincers attachment for a surgical handle has a connecting rod which is axially displaceable by operation of the handle. At the distal end of a shaft there is a laterally opening recess for receiving a clip having compressible legs. The distal end of the connecting rod is connected to a closing rod which presses the legs of the clip together in the recess when the handle is actuated.
