This study presents the performance evaluation of a multi-mode electrosurgical system comprising a cutting and coagulation device, footswitch, and flow control unit, assessed exvivo using bovine pericardium tissue. Electro surgery is a widely employed technique for cutting, coagulating, and ablating soft tissue during surgical interventions, particularly in E NT and general surgery. The Myrac™ electrosurgical unit, equipped with a Tonsillectomy probe and operating across ten discrete power levels in both coagulation and ablation modes, was tested to validate its usability and thermal safety. Functional testing was conducted under simulated clinical conditions, assessing mechanical, electrical, and thermal stability parameters. Real-time surface temperature measurements were recorded using a thermal gun, and system integrity was tested under repeated activation cycles. Results indicated consistent tissue response with minimal variation across all power settings, with peak temperatures ranging from 29°C to 33°C. The findings support the safety and reliability of the device under controlled operating parameters and suggest its potential for safe clinical application.
