Electrosurgical device

摘要

A device for electrosurgery includes a curved-tip probe adapted for insertion into an incision, and a resiliently deformable electrode movable longitudinally within the probe so that the distal end can be projected in an offset direction out of the tip of the probe between a closed position wherein the terminal end of the electrode is closely adjacent the tip to an extended position wherein the terminal end is a greater distance from the tip. A shielding member of flexible and resilient composition extends alongside the probe for shielding the terminal end of the electrode from tissue during surgery. The shielding member may be spring biased toward the closed position and include various electrode engaging arrangements that inhibit lateral movement of the electrode relative to the probe. One embodiment includes a slidable shielding member that enables the device to be used for lateral release or meniscal surgery.
