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.
