This is the generator testing fixture for bipolar mode (vessel sealing). Two concentric aluminum rings submerged in a saline bath replicate the varying tissue impedance seen in human tissue during vessel sealing operations.
This project’s goal is to create a system that allows Medtronic to test their electrosurgical generators. Via the engineering design process, we built a lead screw actuator with an electrode arm to replicate the generator’s arcing behavior in monopolar mode (dissection and coagulation), and a variable load using a saline bath to copy the varying tissue impedance in bipolar mode (vessel sealing).
