Title (EN) SURGICAL INSTRUMENT COMPRISING AN ARTICULATION SYSTEM RATIO
(FR) INSTRUMENT CHIRURGICAL COMPRENANT UN RAPPORT DE SYSTÈME D'ARTICULATION
Abstract:
(EN) A shaft assembly is disclosed comprising a shaft including a proximal end, a distal end, a longitudinal axis extending between the proximal end and the distal end, and an outer housing comprising a shaft radius defined with respect to the longitudinal axis. The shaft assembly further comprises an end effector comprising an end effector frame rotatably coupled to the shaft about a fixed articulation axis positioned laterally offset with respect to the longitudinal axis. The shaft assembly further comprises an articulation driver coupled to the end effector frame at an attachment location, wherein a lateral moment arm is defined between the attachment location and the fixed articulation axis, wherein the lateral moment arm is orthogonal to the longitudinal axis, and wherein the shaft assembly is configured such that a ratio of the shaft radius to the lateral moment arm is minimized.
(FR) L'invention concerne un ensemble tige comprenant une tige comprenant une extrémité proximale, une extrémité distale, un axe longitudinal s'étendant entre l'extrémité proximale et l'extrémité distale, et un boîtier externe comprenant un rayon de tige défini par rapport à l'axe longitudinal. L'ensemble tige comprend aussi un effecteur d’extrémité comprenant un cadre d'effecteur terminal couplé de manière rotative à la tige autour d'un axe d'articulation fixe positionné latéralement décalé par rapport à l'axe longitudinal. L'ensemble tige comprend en outre un dispositif d'entraînement d'articulation couplé au cadre d'effecteur d’extrémité au niveau d'un emplacement de fixation, un bras de moment latéral étant défini entre l'emplacement de fixation et l'axe d'articulation fixe, le bras de moment latéral étant orthogonal à l'axe longitudinal, et l'ensemble tige étant configuré de telle sorte qu'un rapport du rayon de tige au bras de moment latéral est minimisé.
