Abstract: The present invention provides a method of performing laparoscopic surgery using a surgical trocar including an elongated trocar passageway and an access channel disposed in spaced relationship to each other. The access channel includes a gas seal to prevent gas leakage while the access channel is in use, and a valve to close the access channel when not in use. Once, the trocar is inserted into the body cavity, the access channel allows access of catheters and or other small diameter devices without the need for making extra incisions. This allows continued use of the trocar while utilizing the access channel, giving it a dual function usage. The access channel allows devices to be angled away from the trocar once inside the body cavity making device manipulation easier.

Abstract: The present invention provides a surgical specimen retrieval device that allows one-handed use by incorporating a geared spool to amplify take up of a flexible line to close the mouth of the specimen bag after the surgical specimen is deposited in the bag. The retrieval device includes a spool with an attached gear that is rotated by movement of a deployment rod with serrated teeth. A flexible line has a proximal end attached to the spool and the distal end attached to the mouth of the bag. When the deployment reel is moved from an extended position to an inserted position, the spool rotates and pays out flexible line to allow the mouth of the deployed bag to open. Once a specimen is taken and deposited in the bag, the deployment rod is moved from the inserted position toward the extended position. This rod movement rotates the spool to take up the line and close the mouth of the bag.
