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.

Abstract: The present invention discloses a surgical stapler. The surgical stapler includes a first handle part, a second handle part, and an adjustment mechanism. The first handle part comprises a staple cartridge component and a drive component, and the second handle part comprises a staple abutting seat. A locking mechanism is designed on the first handle part or/and the second handle part. The first handle part and the second handle part may rotate via the rotation shaft and lock in a longitudinal direction. The adjustment mechanism is located between the first handle part and the second handle part, which may make the second handle part rotate relative to the first handle part via the rotation shaft thereon.

Abstract: A grounding grid breakpoint diagnostic method for a transient electromagnetic method, based on a transient electromagnetic detection apparatus. The method comprises: (101) disposing a test line at a position above a grounding grid to be diagnosed on the ground, and determining coordinates of a detection point; (102) obtaining information about coordinates of the detection point, and coinciding the center of the transient electromagnetic detection apparatus with the coordinates of the detection point; (103) performing, by the transient electromagnetic detection apparatus, measurement along the test line point by point, so as to obtain measurement data; (104) processing, by using diagram forming software, the measurement data to form a longitudinal resistivity cross-section diagram of the detection point according to a preset formula; (105) determining whether a breakpoint occurs at the detection point according to the longitudinal resistivity cross-section diagram.
