Abstract

An optical surgical device includes a detachable, disposable semi-flexible sheath for insertion into a patient's body. The sheath is provided with plurality of channels. One of the channels receives an endoscope for optical examination of an operative site within the patient. The remaining channels may be used for suction, drainage or irrigation of the operative site. The distal end of the sheath defines a hook-like scraping tool for removing tissue from the patient in the field of view of the endoscope.
