BIPOLAR ELECTROSURGICAL INSTRUMENT WITH REPLACEABLE ELECTRODES |
摘要 |
A bipolar electro-surgical instrument for vessel sealing comprises first, and second members (13, 14) connected by a pivot (15). A pair of jaws (19, 20) have opposable seal surfaces that are designed to grasp vascular tissue, and conduct bipolar electro-surgical current therethrough. Electrodes (11, 12) on the jaws, including the seal surfaces (25) are removable, and disposable. The jaws of the instrument have mechanical interfaces (22, 23) designed to accept replacement electrodes. The instrument further comprises interlocking ratchets (29, 30) designed to hold a constant closure forces between the seal surfaces. Wires (26, 27) extend from the electrodes along one of the members, and are connectible to an electro-surgical generator.
