Abstract: A method for better isolating and removing a large mass of excised tissue from a female patient's abdominal cavity during a laparoscopic surgery includes the steps of: (1) vaginally inserting a collection bag that includes: (a) a flexible and resilient ring adapted to enable: the ring to be distorted for vaginal insertion, a specified ring open area sized to allow the mass of tissue to pass through it, and the ring to be removed from the patient's abdominal cavity through a laparoscopic-surgery-appropriately-sized incision, (b) a sleeve having a flexible wall and open end that is affixed to the ring and a defined interior volume sized so as to allow the mass of tissue to reside in the sleeve, and (2) utilizing the collection bag to contain the mass of tissue.

Abstract: A new concept in laparoscopic trocar systems is presented that could be used with most presently available laparoscopic trocars. The Ethicon XCEL 5 mm trocar is used as the basis for this presentation; however, any other size or system of trocars similarly configured would be compatible with the ZTSS being presented. During laparoscopic surgery trocars often slip out of their original placement through the layers of the abdominal wall surrounding the abdomen. This causes the access to the peritoneal cavity to be lost, often at a critical moment during surgery. This necessitates various maneuvers to replace the trocar which waste time and also predispose the patient to complications such as subcutaneous emphysema and bleeding. The ZTSS would prevent this from happening.
