Abstract
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.
