Abstract
An axial elongate bipolar tissue sealer and method of use by a surgeon for electrosurgery on tissue has a handle. A tube may move axially relative to a chassis on the handle. The effector provides bipolar electrosurgery. A member extending from the distal end is opposite the patient end of the 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 through application of compression and bipolar electrosurgery between the first and second electrodes. The effector and the part have complimentary sealing surfaces for partial mating engagement upon axial movement toward one another. The effector and the part can be removably attached to the distal end or member, respectively.
