The inner wall of the front tube 34 is fixedly connected with a positioning control shaft 35, and the positioning control shaft 35 includes a slide rod 351, the rear end of the slide rod 351 is fixedly connected to the rear side of the inner wall of the positioning front tube 34, the outer wall of the slide rod 351 is fixedly connected with a fixed circular shaft 352, and the outer wall of the slide rod 351 is slidably connected with a slide shaft 353 on the side away from the fixed circular shaft 352, and the outer walls of the slide shaft 353 and the fixed circular shaft 352 are both rotatably connected with rotating rods 354 in an annular array, and the left and right groups of rotating rods 354 are rotatably connected with positioning plates 355 on the side away from the fixed circular shaft 352 and the slide shaft 353, and the slide shaft 35 The front side annular array of the plurality of connecting push rods 356 is fixedly connected to the front side of the plurality of connecting push rods 356, and the front side of the plurality of connecting push rods 356 is fixedly connected to the push plate 357, the control rod 4 includes a push-pull tube 41, the outer wall of the push-pull tube 41 is slidably connected to the inner wall of the slide block 13, a rotating rod connecting groove 42 is opened in the middle of the push-pull tube 41, and the top and the left and right sides of the bottom of the inner wall of the rotating rod connecting groove 42 are rotatably connected to the rotating rods 43 facing in opposite directions, and the rear side of the push-pull tube 41 is fixedly connected to the cylindrical push-pull rod 44, and the rear side of the cylindrical push-pull rod 44 is fixedly connected to the front side of the push plate 357, and the cylindrical push-pull rod 44 The two sides of the outer wall of the two L-shaped push rods 45 are respectively fixedly connected, and the rear sides of the two L-shaped push rods 45 extend to the rear side of the outer wall of the connecting tube shell 31 through the inner side of the connecting tube shell 31 and the positioning tube 33 and are fixedly connected with a control rod push plate 46. The two clamps 2 include a clamp body 21, and the outer walls of the two clamp bodies 21 are respectively slidably connected to the inner wall of the clamp placement rod 14. The rear sides of the inner sides of the two clamp bodies 21 are provided with clamp connection grooves 22. The top and bottom of the inner sides of the two clamp connection grooves 22 are respectively rotatably connected to the left and right sets of rotating rods 43 away from the side of the push-pull tube 41;

[0036] When the internal tissue of the human body needs to stop bleeding, the operator can use the external control device to control the control rod 4. The staff pulls the control rod push plate 46 with the help of a tool, thereby driving the control rod push plates 46 on both sides to pull the cylindrical push-pull rods 44. The cylindrical push-pull rods 44 slide on the inner wall of the slide block 13, pushing the push-pull tube 41 to move backward, causing the two rotating rods 43 to rotate and change the angle. This action causes the two clamping plate bodies 21 to move inward, and the target tissue is clamped on the inside through the closing of the clamping block 24;

[0037] At the same time, when the cylindrical push-pull rod 44 moves backward, it pushes the push plate 357, and then drives the connected push rod 356 to move backward, which prompts the sliding shaft 353 to move backward on the outer wall of the sliding rod 351, causing the rotating rod 354 connected to the outer wall of the fixed circular shaft 352 and the sliding shaft 353 to rotate. The rotation of the rotating rod 354 pushes the positioning plate 355 to move outward, and multiple positioning plates 355 are expanded outward and fixed on the inner wall of the positioning front tube 34, thereby achieving stable fixation of the tissue. Through this precise control mechanism, the operator can ensure the accuracy and safety of the hemostasis process.

[0038] See also Fig.10 The inner front sides of the two clamping plate bodies 21 are respectively fixedly connected with L-shaped clamping blocks 23 facing opposite directions, and the inner front sides of the two clamping plate bodies 21 are both fixedly connected with clamping blocks 24;

[0039] When the two splint bodies 21 move inward, causing the two clamping blocks 24 to close and clamp, the two L-shaped blocks 23 will move towards each other until their inner sides contact each other. As the two splint bodies 21 continue to move, the inner sides of the two L-shaped blocks 23 squeeze each other and generate elastic force, so that the two L-shaped blocks 23 are closely connected to form a stable clamping force. This design ensures the stability and reliability of the clamping process and ensures that the target tissue can be firmly fixed between the splint bodies 21.

[0040] Working principle: When the internal tissue of the human body needs to stop bleeding, the operator can use the external control device to control the control rod 4. The staff pulls the control rod push plate 46 with the help of a tool, which drives the control rod push plates 46 on both sides to pull the cylindrical push-pull rods 44. The cylindrical push-pull rods 44 slide on the inner wall of the slide block 13, pushing the push-pull tube 41 to move backward, causing the two rotating rods 43 to rotate and change the angle. This action causes the two splint bodies 21 to move inward, and the target tissue is clamped in place by closing the clamp block 24. On the inside, when the internal tissue of the human body needs to stop bleeding, the operator can use the external control device to control the control rod 4. The staff pulls the control rod push plate 46 with the help of a tool, and then drives the control rod push plates 46 on both sides to pull the cylindrical push-pull rod 44. The cylindrical push-pull rod 44 slides on the inner wall of the slide block 13, pushing the push-pull tube 41 to move backward, causing the two rotating rods 43 to rotate and change the angle. This action causes the two clamping plate bodies 21 to move inward, and the target tissue is clamped on the inside through the closing of the clamping block 24;

[0041] When the two splint bodies 21 move inward, causing the two clamping blocks 24 to close and clamp, the two L-shaped blocks 23 will move towards each other until their inner sides contact each other. As the two splint bodies 21 continue to move, the inner sides of the two L-shaped blocks 23 squeeze each other and generate elastic force, so that the two L-shaped blocks 23 are closely connected to form a stable clamping force. This design ensures the stability and reliability of the clamping process and ensures that the target tissue can be firmly fixed between the splint bodies 21.

Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
