Self Retaining Laparoscopic Trocar System-Zisow Trocar Sleeve System

摘要

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.
