Abstract

Systems and methods for reducing insufflation loss due to gas leakage during a laparoscopic surgical procedure are provided. The surgical procedure includes the use of a surgical instrument having an end effector and a trocar through which the surgical instrument is inserted for access to the abdominal cavity of a patient receiving laparoscopic surgery. The trocar includes a lip, a lip seal disposed within the lip, and a cannula located beneath the lip. The systems and methods reduce or prevent a loss of insufflation when using conventional systems and methods to insert the surgical instrument through a conventional trocar.
