Abstract
A specimen retrieval system of simplified construction. The system is configured for use during laparoscopic surgery to assist in the retrieval and removal of tissue.
Claims8
A specimen retrieval system, comprising:
- a bag having a flexible basket with an opening configured to be deployable for receiving a tissue specimen, and an elongate string encircling the flexible basket and extending therefrom to terminate remote from the flexible basket, the string being operable to close the opening of the flexible basket;
- an outer cannula having a distal end and a proximal end with a cannula handle located at the proximal end of the outer cannula, the outer cannula having a lumen configured to receive the bag therein and to permit passage of the bag through the distal end of the outer cannula for deployment of the bag, the outer cannula further including an elongate slit adjacent the distal end of the outer cannula configured for enabling positioning of the flexible basket through the slit and for retrieval of the flexible basket through the slit for positioning of the bag within the outer cannula;
- and
- an interior tube having a distal end slidably positionable within the outer cannula via the proximal end of the outer cannula, the interior tube having a tube handle mounted to a proximal end of the interior tube at a location exterior of the cannula handle, a distal aperture defined on the interior tube proximal the distal end of the interior tube and a proximal aperture defined on the interior tube distal the proximal end of the interior tube, the distal and proximal apertures configured for passage of the string into the interior tube via the distal aperture and for passage of the string out of the interior tube via the proximal aperture, and a spring secured within the distal end of the interior tube and extending outwardly of the distal end of the interior tube, the spring connectable to the opening of the basket of the bag.
