Design of a novel three- dimensional-printed two degrees-of-freedom steerable electrosurgical grasper for minimally invasive surgery

In current bipolar electrosurgical instruments, a high frequency electrical sinusoidal wave is passed through the patient's body from an active electrode to the return electrode to cut, coagulate, or desiccate tissues. Even though current bipolar electrosurgical instruments have proven effective in minimizing blood loss, advancement is needed...
