<p>One endoscopic surgical tool is used in conjunction with a laser that is powered through a small diameter laser power tube (14). The tool includes a bendable, rigid tube (24) having a lumen (22) sufficiently larger than the laser power tube (14) such that upon application of an axial, inboard directed force (32), the laser power tube (14) is axially compressed within the lumen (22) of the bendable tube (24). The tool further includes a coupling tube (54) which provides suction through the lumen (22) of the bendable, rigid tube (24). Further enhancements of this tool include an axially movable, soft touch casing (26) surronding the tube (24). The tool may include a handle (50) at the proximal end of the tube (24) and a branch coupler (62) and a second bendable, rigid tube (92) with suction control valves (60 and 72) for the primary bendable tube (24) and the branch bendable tube (92).</p> |
