ABSTRACT:
One endoscopic surgical tool is used in conjunction with a laser that is powered through a small diameter laser power tube. The tool includes a bendable, rigid tube having a lumen sufficiently larger than the laser power tube such that upon application of an axial, inboard directed force, the laser power tube is axially compressed within the lumen of the bendable tube. The tool further includes a coupling tube which provides suction through the lumen of the bendable, rigid tube. Further enhancements of this tool include an axial movable, soft touch casing surrounding the tube. The tool may include a handle at the proximal end of the tube and a branch coupler and second bendable, rigid tube with suction control valves for the primary bendable tube and the branch bendable tube. Another endoscopic tool is an endoscope that includes a palm sized enclosure at a proximal end region of a stem of the endoscopic, a form-fitted palm rest attached to the bottom of the enclosure and flow control valves controlling suction and irrigation. These flow control valves have operator interface controls protruding from the top of the palm sized enclosure such that the endoscope is configured as having trumpet-like controls. Further enhancements of the endoscope include a suction control valve that is biased closed and an operator interface control that is biased upward such that the surgeon/operator variably controls the flow of the suction dependent upon the depression of the operator interface control.
