New electrodes system with radiofrequency scalpel for resection of parenchymatous tissue

摘要

Surgical resection remains the most effective treatment for liver tumors but it can still be limited by blood loss which can affect postoperative recovery and long-term survival. New approach towards achieving bloodless resection is the use of heat coagulative necrosis in healthy liver tissue, creating a zone of necrosis with help of monopolar or bipolar linear array of needle electrodes which are connecting with radiofrequency generator. Resection of liver can be performed by usual scalpel. Unfortunately appreciable hemorrhages are possible after excising part of tissue because of incomplete coagulation.
