Precise temperature control of surgical instruments like surgical pens is a significant challenge in medicine, as elevated temperatures can damage healthy tissues and cause burns, endangering patient safety and affecting surgeons’ focus. Many existing monitoring methods are inefficient. This product utilizes an advanced control system to continuously track the pen’s temperature and alert the surgeon to any unusual increases. Its ability to automatically lower the temperature to a safe level enhances surgical safety, reduces risks from excessive heat, and aids in faster patient recovery.
