The clamping arm assembly comprises an upper jaw and a lower jaw, a window is formed in the upper jaw, a cover plate is movably arranged in the window, a thread clamping seam is formed between the cover plate and the wall face of the window, and an elastic piece is connected between the cover plate and the upper jaw; the upper jaw comprises a limiting part, and the limiting part is located above the thread clamping seam; under the elastic action of the elastic piece, the top surface of the cover plate abuts against the bottom surface of the limiting part for limiting; the stitching instrument comprises a base assembly, a barrel and the clamping arm assembly. After line puncture is completed, a suture is clamped in the suture clamping seam, the suture can be directly taken out of a human body by moving the clamping arm assembly, additional tool operation is not needed, when the suture is pulled to take out the suture, the acting force of the suture on the cover plate is opposite to the pressing direction of the cover plate, and the cover plate cannot be tighter and tighter by pulling the suture; the suture can be taken out as long as the acting force for pulling the suture is larger than the acting force for pressing the cover plate, the suture can be taken out easily, and the risk of pulling the suture apart does not exist during suture taking.

The utility model relates to the technical field of suture testing, and discloses a suture tensile property testing device which comprises a testing table, a groove is formed in the upper surface of the testing table, a stepping motor is fixedly installed on one side of the testing table, a lead screw is rotationally connected to the interior of the groove, and one end of the lead screw is fixedly connected to the output end of the stepping motor. A graduated scale is arranged on the upper surface of the test board, a connecting block is in threaded connection with the exterior of the lead screw and slidably connected into the groove, and mounting frames are fixedly connected to one side of the upper surface of the connecting block and one side of the upper surface of the test board. In the tensile property test of the sewing thread, after the sewing thread is wound by using the wire spool, the outer part of the sewing thread is propped through the pressing plate, so that the clamping force is enhanced, and meanwhile, the friction force is further increased by using the extrusion block, so that the fastening force for clamping the sewing thread is favorably improved; the phenomenon of slippage caused by unstable clamping of the sewing thread in the test is effectively reduced, and the wire spool is convenient to disassemble and assemble.

At least one embodiment of the present disclosure provides a clamping mechanism and a surgical robot, in which a hollow connecting tube is connected with a wire end; a wire storage assembly includes a clamping assembly, a moving driving mechanism and an opening and closing driving mechanism, the clamping assembly is configured to clamp one end of a suture; when the clamping assembly is located in the hollow connecting tube, the suture extends out of the hollow connecting tube from the wire end; the moving driving mechanism is configured to drive the clamping assembly to move in the hollow connecting tube to change the length of the suture outside the wire end and drive the clamping assembly to extend out of or retract into the hollow connecting tube; the opening and closing driving mechanism is configured to drive the clamping assembly to open or close; in response to the clamping assembly being driven by the moving driving mechanism to extend to the outside of the hollow connecting tube, the opening and closing driving mechanism drives the clamping assembly to open to release the suture; when the clamping assembly is opened, in response to the opening and closing driving mechanism driving the clamping assembly to close, the moving driving mechanism drives the clamping assembly to move to retract into the hollow connecting tube.

The application discloses a kind of composite material preform single edge suture line ring forming device and method, device includes suture needle driving unit, suture material clamping unit, suture line clamping unit, line ring forming shape monitoring unit, structure unit;Method is first by suture material clamping unit clamping suture material, suture line is introduced by thread carrier in suture line clamping unit, passes through suture needle and is clamped by thread holder in suture line clamping unit, and suture needle driving unit electric push rod drives suture needle to complete suture action, then by visual sensor in line ring forming shape monitoring unit Real-time monitoring line ring forming shape.Compared with prior art, the shape change of line ring forming is monitored by visual sensor in real time in the present application, the relationship between suture process parameters such as suture needle penetration, suture line directness, suture material thickness and line ring shape in suture process is obtained, and the forming quality law of line ring with suture needle pose under different suture process parameters is ascertained.
