Abstract

A probe (20) for use in minimally invasive surgery incorporates a handle (50), a body tube (60) and an electrosurgical (120) extending through the probe to the distal end (46) thereof. The probe includes a port (56) to a passageway through the body tube (60) for achieving evacuation, irrigation or aspiration at the surgical site controlled by a fluid flow control device (54). Additional devices, such as a video monitor (40) and inflation pump (28), may be utilized in association with the probe (20).
