Description

Technical Field

[0001] This utility model relates to the field of hemostatic clip technology, specifically a multifunctional microscopic hemostatic clip. Background Technology

[0002] In surgical procedures or animal experiments, it is often necessary to clamp specific blood vessels to achieve hemostasis or temporarily close the vessels. In such cases, microscopic hemostatic clips are required.

[0003] Currently available microscopic hemostatic clips are characterized by their small size and flexibility. However, these widely used microscopic hemostatic clips are all made of stainless steel and the clamping force is not adjustable. Based on practical experience, it is known that excessive clamping force or excessive clamping time can cause irreversible tissue damage. On the other hand, insufficient clamping force can lead to incomplete closure of blood vessels and bleeding. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] This utility model discloses a multifunctional microscopic hemostatic clip, including a clamping rod, and the bottom of the clamping rod is provided with a clamping force adjustment mechanism;

[0006] The clamping force adjustment mechanism includes a limiting rod that passes through and slides through the middle of two sets of pressing plates. A connecting ring is fixedly connected to the middle of the side wall of each of the two sets of pressing plates that are close to each other. A movable ring passes through and slides through the left and right sides of the outer periphery of the limiting rod. A synchronization plate is fixedly connected to the bottom of the outer periphery of the movable ring. A threaded plate is fixedly connected to the bottom of each synchronization plate. The threaded plates are respectively threaded to the left and right sides of the outer periphery of the bidirectional screw. The bidirectional screw is rotatably connected to the middle between the two sets of fixed plates.

[0007] As a preferred technical solution of this utility model, a knob is rotatably connected to the left side wall of the fixing plate on the left side, and the knob is fixedly connected to the bidirectional screw.

[0008] As a preferred technical solution of this utility model, the fixing plate is fixedly connected to the left and right ends of the bottom of the mounting plate, and a sliding groove is provided in the middle of the mounting plate.

[0009] As a preferred technical solution of this utility model, the synchronization plate is respectively connected to the left and right sides of the inner side of the slide groove, and the left and right ends of the limiting rod are fixedly connected with baffles.

[0010] As a preferred technical solution of this utility model, a connecting plate is fixedly connected to the lower part of the side wall of the two sets of clamping rods that are close to each other, and the two sets of connecting plates are rotatably connected by a rotating shaft.

[0012] As a preferred technical solution of this utility model, the two sets of connecting rings are fixedly connected to the left and right ends of the springs on their inner sides, and the springs are in clearance fit with the limiting rods.

[0013] The beneficial effects of this utility model are:

[0014] 1. This multifunctional microscopic hemostatic clip, when the clamping force of the hemostatic clip needs to be controlled, the knob is turned to rotate the bidirectional screw. During the rotation of the bidirectional screw, the left and right threaded plates move closer to each other. Under the action of the synchronous plate, the two sets of moving rings move closer to each other. During the movement of the moving rings, the pressing plate pushes the pressing plate on both sides to squeeze, thereby reducing the clamping force of the hemostatic clip, avoiding tissue damage caused by excessive clamping force, and improving the practicality of the hemostatic clip;

[0015] 2. This multifunctional microscopic hemostatic clip, by controlling the clamping force, can maintain its clamping function while minimizing damage to the human body. When the clamping force does not need to be adjusted, the pressure plate can be squeezed directly to use the hemostatic clip, thus improving its applicability. Attached Figure Description

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] Example: Figures 1-4 As shown, the present invention provides a multifunctional microscopic hemostatic clip, including a clamping rod 1, and a clamping force adjustment mechanism 2 is provided at the bottom of the clamping rod 1;

[0024] The clamping force adjustment mechanism 2 includes a limiting rod 8, which restricts the spring 9 and the pressing plate 5. The limiting rod 8 passes through and slides in the middle of the two sets of pressing plates 5. A connecting ring 7 is fixedly connected to the middle of the side wall of the two sets of pressing plates 5 that are close to each other. The connecting ring 7 provides space for the spring 9 to be installed, and at the same time cooperates with the limiting rod 8 to prevent the pressing plate 5 from being squeezed and causing the spring 9 to bend to the side. Moving rings 10 pass through and slide on both sides of the outer periphery of the limiting rod 8. A synchronous plate 11 is fixedly connected to the bottom of the outer periphery of the moving ring 10. The synchronous plate 11 serves to connect and fix the threaded plate 12 and the moving ring 10. The bottom of the synchronous plate 11 is fixedly connected to the threaded plate 12. The threaded plate 12 is threadedly connected to the left and right sides of the outer periphery of the bidirectional screw 13. The bidirectional screw 13 is rotatably connected between the middle of the two sets of fixed plates 16. The rotation of the bidirectional screw 13 can make the threaded plates 12 on the left and right sides move away from each other or move closer to each other.

[0025] A knob 17 is rotatably connected to the left side wall of the left fixing plate 16. The knob 17 is fixedly connected to the bidirectional screw 13. The fixing plate 16 is fixedly connected to the left and right ends of the bottom of the mounting plate 14. A slide groove 15 is provided in the middle of the mounting plate 14. Rotating the knob 17 can drive the bidirectional screw 13 to rotate. The synchronizing plate 11 can slide inside the slide groove 15. The slide groove 15 is provided to connect and fix the synchronizing plate 11 to the threaded plate 12.

[0026] Synchronous plates 11 are respectively connected to the left and right sides of the inner side of the slide groove 15. Baffles 18 are fixedly connected to both ends of the limiting rod 8. Connecting plates 3 are fixedly connected to the lower part of the side wall of the two sets of clamping rods 1 that are close to each other. The two sets of connecting plates 3 are rotatably connected by a rotating shaft 4. The connecting plates 3, springs 9 and rotating shaft 4 cooperate to enable the hemostatic clamp to clamp. Baffles 18 are set to prevent the moving ring 10 from falling off the outside of the limiting rod 8, which would prevent the clamping force adjustment mechanism 2 from functioning.

[0027] Pressing plates 5 are all set at the bottom of clamping rods 1. Clamping blocks 6 are set at the top of the two sets of clamping rods 1 on the side that are close to each other. The two sets of connecting rings 7 are fixedly connected to the left and right ends of springs 9. Springs 9 are in clearance fit with limit rods 8. Springs 9 are set to enable clamping rods 1 to have clamping force.

[0028] Working principle: When it is necessary to control the clamping force of the hemostatic clip, turn the knob 17 to rotate the bidirectional screw 13. During the rotation of the bidirectional screw 13, the left and right threaded plates 12 move closer to each other. Under the action of the synchronization plate 11, the two sets of moving rings 10 move closer to each other. During the movement of the moving rings 10, they push the pressing plate 5 to squeeze the pressing plates 5 on both sides, thereby reducing the clamping force of the hemostatic clip and avoiding tissue damage caused by excessive clamping force. When it is not necessary to adjust the clamping force, the pressing plate 5 can be squeezed directly to use the hemostatic clip.
