Tungsten needle plays an important role as an ablation electrode in an electrosurgical pencil. The electrosurgical pencil having an ultra-sharp high-melting tungsten electrode combines the five dings of attraction, electrocoagulation, electrocutting, scraping, and pushing and peeling, so there is no need to frequently change instruments during the operation, thereby saving a lot of time. It reduces intraoperative bleeding, has clear anatomical surface, to greatly improve the quality of surgery. And the gas generated during electrocoagulation is exhausted at any time to protect the medical staff.

There are various specifications of tungsten needles for applying as ablation electrodes, to meet requirements on various shallow and deep surgeries. The tungsten electrode can be retracted, effectively cooperate with the liquid suction and smoking suction during the operation, and effectively remove the scorching and sticking of the electrode tip generated during the operation. And therefore, it is suitable for all kinds of cholecystectomy, retroperitoneal tumor resection, thyroid and breast surgery, etc.
