ABSTRACT:
Lung clamp end effectors for a thoracoscopic surgical instrument are disclosed. The lung clamp end effectors have a base portion, an intermediate portion, and a distal portion. Each base portion has a first through-hole for pivotally engaging a pin of the clevis of the thoracoscopic surgical instrument, and preferably, a second through-hole used in conjunction with connecting links which connect the lung clamp end effector to the push rod. The through-holes on a particular end effector are located on opposite sides of the longitudinal axis of the tool, thereby providing strong clamping action. The lung clamps are further arranged with their distal portions increasing in width to approximately 10 mm as they extend distally. The distal portion also have cut-outs which increase in width as they extend distally. The lung clamp end effectors are at least two inches long from their respective pivot through-holes to their respective distal ends.
