Title
(EN) COMPRESSION AND FIRING FORCE SENSOR FOR CIRCULAR SURGICAL STAPLER
(FR) CAPTEUR DE FORCE DE DÉCLENCHEMENT ET DE COMPRESSION POUR AGRAFEUSE CHIRURGICALE CIRCULAIRE
Abstract
(EN) A surgical instrument includes a housing assembly, a movable member, an anvil, and a force sensing assembly. The housing assembly includes a first housing, a second housing, and a deck surface that includes at least one annular array of staple openings. The force sensing assembly includes at least one of a compression force sensor disposed between the first and second housings or a tension force sensor coupled with the movable member or the anvil. The compression force sensor is configured to sense a compression force communicated longitudinally through the first and second housings during at least one of compressing tissue between the anvil and the deck surface or firing the surgical instrument. The tension force sensor is configured to sense a tension force communicated longitudinally through the movable member during at least one of compressing tissue between the anvil and the deck surface or firing the surgical instrument.
(FR) La présente invention concerne un instrument chirurgical qui comprend un ensemble boîtier, un élément mobile, une enclume et un ensemble de détection de force. L'ensemble boîtier comprend un premier boîtier, un second boîtier et une surface de plateau qui comprend au moins un réseau annulaire d'ouvertures d'agrafes. L'ensemble de détection de force comprend au moins l'un d'un capteur de force de compression disposé entre les premier et second boîtiers ou d'un capteur de force de tension couplé à l'élément mobile ou à l'enclume. Le capteur de force de compression est conçu pour détecter une force de compression communiquée longitudinalement à travers les premier et second boîtiers pendant au moins l'un de la compression de tissu entre l'enclume et la surface de plateau ou du déclenchement de l'instrument chirurgical. Le capteur de force de tension est configuré pour détecter une force de tension communiquée longitudinalement à travers l'élément mobile pendant au moins l'un de la compression de tissu entre l'enclume et la surface de plateau ou du déclenchement de l'instrument chirurgical.
