ABSTRACT:
An axial elongate bipolar tissue sealer/cutter and method of use by a surgeon for electrosurgery on tissue. A chassis on a handle extends axially for axial movement. An effector on a distal end of the chassis first contacts tissue with axial movement. The effector provides bipolar electrosurgery. A member extending from the distal end is opposite the patient end of a tube. A part on the member is transverse to the axis to conduct electrosurgery. First and second bipolar electrodes on the effector and part are electrically isolated. A generator for bipolar electrosurgery supplies the electrodes. An activator is movably supported on the handle connects to the tube and/or chassis to axially move the patient end and its effector relative to the part. Tissue and bodily fluid therebetween are sealed or cut through application of compression and bipolar electrosurgery between the first and second electrodes. The effector and the part have complimentary sealing or cutting surfaces for partial mating engagement upon axial movement toward one another.
