ELECTROSURGICAL GENERATOR WITH IMPROVED CIRCUITRY FOR GENERATING RF DRIVE PULSE TRAINS

摘要

An electrosurgical generator comprises a patient circuit which includes an active electrode and a return electrode. The generator generates a pulse train and includes an MXN storage device having M memory locations where M > 1 and each location having N storage positions where N ? 1. The storage device stores at least one K-bit binary signal which is sequentially put out from the storage device. An electrosurgical signal generating circuit which is response to the K-bit binary signal generates an electrosurgical signal which is applied to the patient circuit.
