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. When the rod is moved to a fully retracted position, the teeth on the rod disengage from the gear, which allows the spool to rotate freely. The device is then removed from the trocar and the line is used to pull the bagged specimen from the body cavity.
