摘要：
A surgical stapling device (10, 16) comprising: an elongated body portion (14, 518) defining a longitudinal axis； a tool assembly (20) supported at a distal end of the elongate body portion, the tool assembly defining a longitudinal axis and including a stopper assembly and a cartridge assembly (22), the stopper and cartridge assembly being relatively movable between open and closed positions, the tool assembly being supported for articulation around an axis that is perpendicular to the longitudinal axis of the elongated body portion and being movable from a first position in which the longitudinal axis of the tool assembly is aligned with the longitudinal axis of the elongated body portion, to a second position in which the longitudinal axis of the tool assembly is at an angle with the longitudinal axis of the elongated body portion； an articulation element (602) that is operatively coupled with the tool assembly and that is movable to move the tool assembly between the first and second positions； and a retention element (674) for releasably engaging the articulation element, the retention element preventing movement of the articulation element until a predetermined force is applied to the articulation element. where the retention element includes a spherical protrusion formed in a monolithic manner that extends from the elongated body and is positioned to contact the articulation element； and where the protrusion is formed in a flexible wall (678) such that when a predetermined force is applied to the articulation element, the flexible wall flexes away from the recess to allow the articulation element to move.Un dispositivo de grapado quirúrgico (10, 16) que comprende: una porción de cuerpo alargado (14, 518) que define un eje longitudinal； un conjunto de herramienta (20) apoyado en un extremo distal de la porción de cuerpo alargado, el conjunto de herramienta definiendo un eje longitudinal e incluyendo un conjunto de tope y un conjunto de cartucho (22), el conjun
