Abstract
An electrosurgical coagulation instrument specifically designed to be insertable through a cannula for use in coagulating tissue during a laparoscopic or other scope-type procedure. The instrument has both bipolar forceps jaw paddles and bipolar needle electrodes. The needle electrodes are selectively extendable from the distal end of the instrument by manipulation of a knob member in a proximal handle. The needle electrodes can be extended to thereby enter certain tissue such as a tumor to thereby effectuate desiccation thereof and a gradual shrinkage.
