Abstract
An endoscopic surgical instrument for aspiration, irrigation, and blowing gas adjacent a surgical site is provided. The instrument includes a handle portion and a cannula member extending distally from the handle portion. First and second connection ports are supported by the handle and are in fluid communication with the cannula member. An insertion port is also supported by the handle portion and is preferably axially aligned with the cannula member. A blow tube is removably positioned within the cannula member via the insertion port. The first and second connection ports are adapted to communicate with a source of irrigation fluid and a vacuum source and the blow tube is adapted to be connected to a source of pressurized gas such that irrigation fluid, aspiration, and/or pressurized gas can be selectively provided via the cannula member at the surgical site.
