BIPOLAR ELECTROSURGICAL INSTRUMENT WITH REPLACEABLE ELECTRODES
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,...

Abstract | 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.
Cet instrument bipolaire d'électrochirurgie destiné à souder des vaisseaux comporte deux éléments reliés par un pivot. Les deux mâchoires de cet instrument portent des surfaces de soudage opposées conçues pour saisir des tissus vasculaires et faire passer un courant bipolaire chirurgical. Les électrodes se trouvant sur les surfaces de soudage sont amovibles et jetables. Les mâchoires de cet instrument possèdent des organes de jonction mécanique permettant le remplacement des électrodes. Cet instrument comporte également des rochets de verrouillage conçus pour maintenir constante la force de fermeture s'exerçant sur les surfaces de soudage. Des fils, qui partent des électrodes et courent le long de l'un des éléments, peuvent être connectés à un générateur de courant électrique chirurgical. |
