SURGICAL HANDLE HAVING A CONTROLLED LEAK PASSAGE

摘要

A surgical handle (12) for use with an endoscopic instrument (14) that is insertable into a body cavity insufflated with a gas. The surgical handle (12) includes a housing having a mount that defines an opening for receiving the endoscopic instrument. A first elongated pusher tube is located within the housing and aligned with the mount opening. The pusher tube includes an interior passage that is in fluid communication with the endoscopic instrument. A first actuator moves the pusher tube longitudinally with respect to the mount opening. The interior passage is sized to permit the flow therethrough of insufflation gas escaping from the body cavity up to a predetermined rate, the rate being set at an amount that will not result in deflation of the body cavity.
