ABSTRACT:
A combined mechanical cutter and laser function surgical instrument, constructed with; a handle housing and a disposable tip assembly removably mounted to the handle housing. The disposable tip assembly has a hollow tube with a proximal and a distal end, a stationary jaw mounted to the distal end of the hollow tube, a movable jaw which pivots relative to the stationary jaw and a actuating mechanism coupled to the movable jaw for moving the movable jaw, the actuating mechanism being driven from linkage in the handle housing mounted to the proximal end of the hollow tube. Quick disconnects are mounted on the proximate end of the hollow tube to engage the handle housing and a laser energy conductive optic fiber extends through the hollow tube and mounted to the stationary jaw. A laser energy dispensing tip member is mounted on and insulated from the stationary jaw and is connected to the optic fiber to transport laser energy from a remote laser energy generator.
