Abstract
The bipolar modular forceps assembly is a disposable electrosurgical device utilized with an RF voltage supply to weld soft tissue to prevent bleeding when cut or excised. The device consists of two modularly constructed arms arranged in scissor configuration that clamp when the arms are apart and open when the arms are squeezed together. The wires enter from the rear of the device, behind the digit insertion of the upper arm, and run through the interior of the upper arm before reaching the pivot point. From the pivot joint, one wire continues to the bottom jaw and the other wire wraps around the pin bushing in the pivot joint and proceeds to the top jaw. At all times the wires are fully insulated by the insulative cover with the only exposed wire occurring where they enter the device. The bipolar voltage of each wire is transferred to an electrode on each jaw. The electrodes are insulated from surrounding tissue by the insulative jaw, which contains visible markings showing the beginning, middle and end of the electrode. Both the insulative jaw and the electrode are interchangeable and made from moldable material to allow for different sizes and shapes. When no voltage is applied the tool can be used as a blunt dissector.
