Abstract
A bipolar surgical instrument that includes opposing grips that can engage the tissue. A current is delivered from an electrosurgical power source to electrodes disposed on the grips to cauterize the tissue. The electrode configurations provide efficient cauterization of the tissue. In some embodiments, the positive and negative electrodes will be offset from each other to prevent shorting and to provide a thin line of coagulation heating to the gripped tissue. In some embodiments the electrodes are removably coupled to the grips through nonconductive sleeves. In some embodiments, the first electrode is disposed in a groove and the second electrode is disposed on a boss.

61. An electrosurgical instrument comprising:
-
a first body comprising;
a second body rotatably coupled to the first body;
a first effector and a second end effector rotatably coupled to the second body, wherein the first and second end effectors each comprise a proximal portion and a distal portion, wherein the proximal portions of the first and second end effectors comprise a nonconductive body;
wherein the distal portions of the first and second end effectors comprise a substantially triangular shaped conductive grip body for gripping a target tissue;
a first lead coupled to the first end effector and a second conductive lead coupled to the second end effector, wherein the first and second leads are attachable to a power source to deliver energy to the distal portions of the first and second end effectors. - View Dependent Claims (62, 63, 64, 65, 66, 67, 68, 69)
