发明名称 Trocar facilitator for endoscopic surgery and method of using the same
摘要 A trocar system for assisting in the generation of endosurgical ports is disclosed in which a trocar facilitator is used to place the peritoneum in counter-traction to facilitate the penetration of the trocar. Peritoneal counter-traction results in increased surface tension which reduces the force and downward momentum necessary to achieve trocar penetration, thereby eliminating the risk of excess penetration and injury to internal organs. The facilitator is of a corkscrew-like design, with an attached support ring and a removable guide piece having a hollow, cylindrical passageway which aids in the insertion and support of the trocar, cannula, and other endoscopic surgical instruments. In another embodiment, the facilitator is configured to aid in the introduction of carbon dioxide gas into the abdominal cavity of the patient. An improved curved tip of the blade of the trocar facilitator is also disclosed.
