SURGICAL TISSUE RETRIEVAL INSTRUMENT AND METHOD OF USE OF A SURGICAL TISSUE RETRIEVAL INSTRUMENT

摘要

A surgical tissue retrieval instrument has a collapsible pouch at the distal end of an elongated pusher rod that is introduced into a patient through a cannula. The instrument includes a two-jaw fork that forms a loop when in an unconstrained configuration and that supports the pouch. Deployment and operation of the fork and the pouch are controlled by a securing mechanism. The two jaws and the securing mechanism are slid in a hem surrounding the opening of the pouch when the device is assembled.

主权项

1. A tissue retrieving device comprising:
a) a sleeve having a proximal end and a distal end, said distal end adapted for insertion in a cannula; b) a rod in slidable communication with said sleeve, said rod having a distal end supporting a u-shape rotating around an open end of the u-shape and laterally biased jaws and a proximal end comprising a handle to manipulate the rod; and c) a pouch in slidable communication with the jaws and the u-shape wherein said jaws and the u-shape comprise a means for deployment and control of repeated opening and closing of said pouch.
