Method and system for continuity testing of medical electrodes
Abstract
An electrosurgical generator is provided which includes a continuity test circuit assembly for testing electrical continuity through an electrode of an electrosurgical instrument. The continuity test circuit assembly includes a test power source providing electrical test energy to a first conductor which is in electrical communication with the electrode and the electrosurgical generator and to at least one second conductor which is coupled to the first conductor for providing a path for current to flow between the first conductor and the at least one second conductor for establishing a test path through which the test energy flows between the first conductor and at least one conductor of the at least one second conductor. The continuity test circuit assembly further includes energy detection circuitry positioned along the test path for detecting the flow of the test energy through the test path for determining electrical continuity through the electrode.
