Surgical instrument and method
TL;DR: In this paper, the authors describe a surgical instrument useful for laparoscopic surgery comprising an insulated shaft, a control means and a connection to an electrosurgical radiofrequency power source, its distal end having a tissue-engaging ledge, and the shaft supporting a tissueengaging clamping or cutting member movable toward the ledge in response to the control means so that an artery or other tissue in the pocket of the J-hook can be clamped or cut while radiofrequency current is applied.
