APPARATUS FOR ELECTRO-SURGICAL TISSUE REMOVAL |
摘要 |
An electro-surgical device (11) for performing tissue resection and cauterization includes an elongated body, a pair of arms extending from a distal end of the elongated body, and an electrode (12) in communication with the pair of arms. The elongated body is adapted to be coupled to a source of energy at a proximal end. The electrode (12) has a first region coated with an insulative coating and a second region for focusing energy emission. The coating can be a diamond-like carbo n coating or other coating exhibiting resistance to cracking at high temperatures and high voltages. The coating can be deposited on a ba se section of a loop electrode (14) while the end sections remain free of the coating. Alternatively, the coating can be unevenly deposited on the electrode. In other embodiments, the electrode can comprise a rollerball and the insulative coating can be deposited on selecte d or random portions of the rollerball. The insulative coating prevents energy loss to fluid and tissue during the operation, thus allowing resection and cauterization to be efficiently performed.
