ABSTRACT:
A surgical instrument assembly for a snare cauterization operation comprises a tubular member having a diameter sufficiently small so that the tubular member can be inserted through a biopsy channel of a flexible endoscope. Multiple endoscopic instrument including a cauterization loop, a flexible web member connected to the cauterization loop or to an auxiliary loop so as to form a capture pocket, and an elongate flexible fluid feed tube provided at a distal end with a needle point and an aperture, are slidably disposed in the tubular member. The fluid feed instrument is used to expand a flat or nonprojecting polyp prior to severing thereof with the cauterization loop and capture of the severed polyp with the web member or pocket.
