Abstract

An energy-based surgical instrument is configured to permit selective cutting, coagulation, and fine dissection required in fine and delicate surgical procedures. The scissors grip instrument provides for tube-in-tube construction so the device is useful for both open and minimally invasive procedures. The assembly includes a clamping mechanism, including a clamp arm and/or housing which are specifically configured to create a desired level of tissue clamping forces.
