Method of making flat loop bipolar electrode tips for electrosurgical instrument

摘要

A method is provided for making an electrode tip for use in a bipolar electrosurgical instrument from a single flat blank of metal. The method uses a photo chemical machining process. The resultant electrode tip has a generally loop shaped working portion. Use of the flat blank of metal results in electrodes having working portions with sharp edges in cross- section. The working portions emit concentrated energy in the radial direction.
