ABSTRACT:
A resectoscope for prostate surgery is provided which includes a rotating cutting element mounted within an outer sheath adapted to be inserted into the urethra. The cutting element has helical threads along the length thereof and a cutting blade at its distal end. The outer sheath has a covered distal end portion which extends beyond and over the cutting blade and has an opening therethrough adjacent the cutting blade. Within the outer sheath is an inner sheath surrounding the cutting element except for the cutting blade. A fiber optic laser filament connected to a laser generator is positioned within the space between the inner and outer sheaths and extends along the length of the inner sheath to a position adjacent the cutting blade. The optic filament is surrounded by a third sheath and is adapted to be moved by the rotation of the cutting element so that the laser light beam from the optic filament advances through tissue to cut and coagulate the resected area before the cutting blade of the cutting element reaches the resected tissue. Irrigation fluid is provided to the area between the inner and outer sheaths and is withdrawn through the inner sheath. A telescope is also provided through the cutting element for viewing the area being resected. The invention further provides for the use of ultrasound in conjunction with the laser resectoscope to plot the area of the prostate to be removed and with the assistance of a computer to control the operation of the laser to prevent cutting of tissue beyond the area of tissues to be removed.
