Abstract:
1. An electrosurgical probe, comprising: a shaft having a shaft distal end and a shaft proximal end; an electrode support articulated with respect to the shaft distal end; an active electrode disposed on the electrode support; a return electrode extending distally from the shaft distal end, wherein the return electrode is adapted as a conduit for transportation and discharge of an electrically conductive fluid; an actuator unit for shifting the probe between an open configuration and a closed configuration; a handle affixed to the shaft proximal end, wherein the actuator unit is disposed on the handle, wherein the handle accommodates a connection block, the connection block adapted for coupling the active electrode and the return electrode to a high frequency power supply; and a mode switch for switching the power supply between a sub-ablation mode and an ablation mode.
