Vascular Clamps

Clamping the renal hilum during a laparoscopic partial nephrectomy has now provided the surgeon a way to duplicate the open technique by creating a clear operative field. Various thermal devices have been used to reduce bleeding during the excision of the tumor, such as ultrasonic shears, bipolar, monopolar, argon coagulator and more. However, the tissue becomes charred, resulting in poor visualization of tumor margins.
