US Patent 7507232 Flexible electrosurgical electrode with manipulator

An electrosurgical instrument that is configured for use in MIS electrosurgical procedures, comprises a handpiece with a separable electrosurgical electrode in the form of a micro-fiber, comprising a long, thin, flexible, insulated wire. The combination is configured to cooperate with the cannula of an endoscope to reach interior tissue. The handpiece is constructed to allow the tip with the micro-fiber active end to be deflected to navigate the fiber end in diverse directions under control of the user, and also allows the deflected position to be releasably clamped with the same hand that manipulates the micro-fiber active end.
