Abstract
A specimen retrieval device is provided. The specimen retrieval device includes a housing including an outer shaft extending distally therefrom. An inner shaft is disposed within the outer shaft and includes at least one tissue engaging device configured to engage tissue and at least one spring. A pouch is coupled to the inner shaft and the at least one spring. The pouch includes an open proximal end and a closed distal end and is movable from a first configuration for deployment from the outer shaft to a second configuration for receiving tissue therein. The at least one tissue engaging device is positionable within the pouch and movable along the inner shaft for engaging tissue and pulling the tissue within the pouch.

A specimen retrieval device, comprising:
- a housing including an outer shaft extending distally therefrom;
- an inner shaft disposed within the outer shaft, the inner shaft including at least one tissue engaging device configured to engage tissue and at least one spring;
- and
- a pouch coupled to the inner shaft and the at least one spring, the pouch including an open proximal end and a closed distal end and movable from a first configuration for deployment from the outer shaft to a second configuration for receiving tissue therein,
- wherein the at least one tissue engaging device is positionable within the pouch and movable along the inner shaft for engaging tissue and pulling the tissue within the pouch.
A specimen retrieval device, comprising:
- a housing including an outer shaft extending distally therefrom;
- an inner shaft disposed within the outer shaft and deployable therefrom, the inner shaft including at least one channel and at least one spring, the at least one channel having at least one tissue engaging device positioned therein for longitudinal movement therealong;
- and
- a pouch coupled to a distal end of the inner shaft and the at least one spring so as to abut at least a portion of the at least one channel of the inner shaft, the pouch including an open proximal end and a closed distal end and movable via the at least one spring from a first configuration for deployment from the outer shaft to a second configuration for receiving tissue therein,
- wherein the at least one tissue engaging device is movable within the pouch along the at least one channel of the inner shaft for engaging tissue and for pulling tissue within the pouch.
A method for removing tissue from a body of a patient, comprising:
- inserting an outer shaft of a specimen retrieval device within a body cavity of a patient;
- deploying an inner shaft of the specimen retrieval device from the outer shaft to move a pouch of the specimen retrieval device from a first configuration to a second configuration;
- positioning at least one tissue engaging device provided on the inner shaft towards a proximal end of the pouch for engaging tissue;
- engaging tissue of interest;
- positioning the at least one tissue engaging device towards a distal end of the pouch for pulling tissue within the pouch;
- and
- removing the pouch from the body cavity of the patient.
