Title
(EN) ELECTROSURGICAL INSTRUMENT END EFFECTOR WITH COMPLIANT ELECTRODE
(FR) EFFECTEUR TERMINAL D'INSTRUMENT ÉLECTROCHIRURGICAL AVEC ÉLECTRODE SOUPLE
Abstract
(EN)
An end effector for operating on tissue comprises an upper jaw, a lower jaw, a flexible member, and a pair of conductive members. The upper jaw and the lower jaw are configured to receive tissue when in an open position and the upper jaw is movable toward the lower jaw. The flexible member is coupled to either the upper jaw or the lower jaw, and is configured to deform in response to compression of tissue between the jaws. One of the conductive members is associated with the flexible member and is configured to move with the flexible member in response to compression of tissue between the jaws. The end effector may be configured to manipulate the position of muscle within tissue in response to compression of tissue between the jaws.
(FR)
L'invention concerne un effecteur terminal opérant sur un tissu et comprenant une mâchoire supérieure, une mâchoire inférieure, un élément souple et une paire d'éléments conducteurs. La mâchoire supérieure et la mâchoire inférieure sont conçues pour accueillir le tissu dans une position ouverte et la mâchoire supérieure peut bouger en direction de la mâchoire inférieure. L'élément souple est couplé à la mâchoire supérieure ou à la mâchoire inférieure, et est conçu pour se déformer en réponse à la compression du tissu entre les mâchoires. L'un des éléments conducteurs est associé avec l'élément souple et est conçu pour se déplacer avec l'élément souple en réponse à la compression du tissu entre les mâchoires. L'effecteur terminal peut être conçu pour manipuler la position du muscle au sein du tissu en réponse à la compression du tissu entre les mâchoires.
