Design of Improved Electrosurgical Unit with Pad Plate Design

Abstract

Diathermy is an electrosurgical unit which is frequently used in surgical operation for cutting purpose. It is an advanced method which overcomes the drawback of scalpel blade. Scalpel blade leads to cutting injuries and heavy blood loss during the surgical operation. This problem can be rectified using diathermy. Diathermy procedure is done by electrical spark, which require deep tissue cutting. Now a day’s most of the surgeons prefer diathermy than scalpel blade, but present surgical unit creates few problems like burning and scaring due to improper construction of grounding (pad) plate. This paper proposes to reduce the electrical burning effect, the pad plated coated with silver material and hyperbolic shape pad plate. Mechanical stuck in the footswitch avoided by using parallel connection of micro switch. The implementation of pad plate design and footswitch model minimizes the electrosurgical burn during the operation.
