AN ELECTRICAL INSULATION TESTING DEVICE AND METHOD FOR ELECTROSURGICAL INSTRUMENTS

摘要

A device (10) suitable for testing the integrity of insulation coating an electrosurgical instrument (30) is described. The device includes a test sleeve (14) and a fault detection unit (12). The test sleeve (14) is generally tubular and defines an open bore with a resilient conductive lining (52) mounted therein. The fault detection unit (12) is coupled to the conductive lining (52) such that establishment of an erroneous current path between the conductive lining (52) and an electrosurgical device (30) is detected.
