Abstract

An instrument for positioning operating tubes in endoscopic operations. A distally pointed cannula tube serves as a guiding probe for introduction into a patient's body so that the distal end is disposed closely proximate the operating site, and carries a handle that is removably attached to the cannula tube proximal end. The cannula tube is hollow for receiving therethrough a mandarin. The mandarin and tube handle are removed from the cannula tube once the tube is inserted into the patient's body, thus leaving only the cannula tube extending into the body of the patient to serve as a guiding probe for one or more operating tubes.
