Abstract: Disclosed is an end effector for a stapler, including a knife holder, and a staple cartridge unit and a staple anvil which are pivotally connected to achieve relative opening and closing. The staple cartridge unit includes a staple cartridge base and a detachable staple cartridge assembly. The knife holder includes a knife holder body and a limiting projection. The limiting projection is arranged between the knife holder body and the knife holder body. When the staple cartridge assembly is detached or mounted relative to the staple cartridge base, the limiting projection of the knife holder abuts against a proximal end portion of the staple cartridge base to stop the staple cartridge base. When the knife holder leaves the initial retraction position, the limiting projection of the knife holder is separated from the staple cartridge base.

Abstract: The present application relates to a surgical instrument with a pivotable effector, including an effector at a distal end, a controller at a proximal end, and an extension tube between the effector and the controller, wherein the extension tube is movably connected to a distal end of the controller; a distal end of the extension tube is pivotally connected to a proximal end of the effector; the extension tube forms a connection channel for transferring an action of the controller to the effector; the controller includes a articulation control mechanism capable of moving in at least one direction; the extension tube includes a first flexible component, and moves in at least one direction through the articulation control mechanism, and the first flexible component provides a rotation torque for the effector, and drives the effector to rotate towards at least one side relative to the distal end of the extension tube.

Abstract: Disclosed is an adaptive drive beam structure, including a plurality of drive beams (1, 2, 3, 4, 5), a central shaft joint (7) and a drive beam joint (6), wherein the plurality of drive beams (1, 2, 3, 4, 5) are mounted in the central shaft joint (7) through the drive beam joint (6), and when a staggered front and back occurs among the plurality of drive beams (1, 2, 3, 4, 5), the drive beam joint (6) is capable of compensating the mismatch of the plurality of drive beams through rotation movement, such that the plurality of drive beams (1, 2, 3, 4, 5) are simultaneously in contact with the drive beam joint (6) all the time. The adaptive drive beam structure is applied to rotating type device products, thereby improving the stress of flexible drive beam in a device, ensuring that the plurality of drive beams are stressed uniformly in the movement process, reducing the deformation of a single piece drive beam and ensuring the movement smoothness of the firing drive beams.
