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...

Design of a 3D printed steerable bipolar electrosurgical tool

Current electrosurgical instruments often lack the capability to be optimally customized to a certain procedure/patient. It simply wouldn’t be feasible to produce ten or hundred different configurations in terms of dimensions and geometry of the same device. Most instruments come in one configuration. This study aims to increase the flexibility...
