Abstract
An electrosurgical system includes an electrosurgical generator, for generating radio frequency power, and an electrosurgical instrument including an electrode assembly. The electrosurgical instrument is detachably connectible to the generator such that radio frequency power can be conveyed to the electrode assembly. The generator includes a counter incremented each time an electrosurgical instrument is connected to the generator, and the electrosurgical instrument includes a memory device capable of recording the value of the counter when the electrosurgical instrument is connected to the generator. The system further includes a comparison unit capable of comparing the current value of the counter with the value of the counter stored in the memory device, and generating a signal when the difference between the two values of the counter is greater than a predetermined threshold.
