Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a vascular fixation clip for coronary artery bypass surgery. Background Technology

[0002] Coronary artery bypass surgery is an important medical procedure for treating coronary artery disease. It improves the heart's blood supply by creating new vascular pathways to bypass narrowed or blocked coronary arteries. In this complex and delicate medical process, doctors need to use a variety of sophisticated medical tools to ensure the success of the surgery, among which vascular fixation clips are an indispensable tool.

[0003] During coronary artery bypass surgery, doctors need to use vascular fixation clips to precisely clamp and fix the blood vessels in order to perform subsequent surgical procedures. These clips can effectively prevent the blood vessels from sliding or shifting during the operation, thereby greatly improving the safety and success rate of the surgery.

[0004] In coronary artery bypass surgery, vascular fixation clips can experience slight displacement when fixing blood vessels, especially under the dynamic environment of cardiac pulsation. The position and tension of blood vessels are constantly changing, and the fixation clips can cause slight displacement of the blood vessel position due to cardiac vibration and vascular peristalsis, affecting the accuracy of vascular anastomosis. Existing fixation clips have an adjustable structure, allowing surgeons to adjust the size of the clip within a certain range according to the actual diameter of the blood vessel, much like using adjustable forceps, improving adaptability to different blood vessel sizes. However, the adjustable structure increases the complexity of the fixation clip, and the complex distribution of blood vessels makes it difficult to precisely control the adjustment structure, thus affecting the smooth progress of the surgery. Therefore, a vascular fixation clip for coronary artery bypass surgery is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a vascular fixation clip for coronary artery bypass surgery, which aims to improve the problem that the adjustable structure of the existing technology increases the complexity of the fixation clip, and the complex distribution of blood vessels makes it difficult to accurately control the adjustable structure.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a vascular fixation clip for coronary artery bypass surgery, including a clip plate, a rubber block slidably connected to the inner wall of the clip plate, a locking mechanism provided on the right side of the clip plate for fixing the clip plate and preventing loosening during clamping, a replacement mechanism provided on the front side of the clip plate for replacing blood vessels of different sizes; the locking mechanism includes a rack, the left end of which is fixedly connected to the left side of the inner wall of the clip plate, a fixing box connected to the right side of the clip plate, a toothed groove on the front side of the inner wall of the fixing box, a top column slidably connected to the rear side of the fixing box, a spring fixedly connected to the outer wall of the top column, and elastic components provided on the left and right sides of the rubber block.

[0007] As a further description of the above technical solution:

[0011] As a further description of the above technical solution:

[0012] The replacement mechanism includes multiple protrusions, and the opposite sides of the multiple protrusions are fixedly connected to the adjacent side of the clamping plate.

[0013] As a further description of the above technical solution:

[0014] Each of the adjacent sides of the clamp is fixedly connected with a sealing strip, and the inner walls of the two sealing strips are slidably connected to the outer wall of the rubber block.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the blood vessel is clamped by pressing the clamp plate. At this time, the rubber block bends with the clamp plate. At the same time, the right end of the rack passes through the clamp plate and slides into the fixing box. Under the push of the spring, the top column exerts a squeezing force on the rack, so that the rack and the tooth groove are tightly engaged, thus locking the clamp plate. Then, by pressing the rack backward, the top column can be pushed to move relative to each other, thereby releasing the rack and the tooth groove from each other. Under the action of the spring and the rubber block, the clamp plate unfolds, making it convenient for continued use later.

[0023] 2. In this utility model, the plug plate and the plug slot are precisely plugged in, and the plug plate is quickly attracted by the magnet in the plug slot. At the same time, the locking plate is inserted into the locking slot and locked by the arc plate at one end of the locking plate. The clamping plate can be replaced according to actual needs. The size of the clamping plate is different and can be used to clamp blood vessels of different sizes. When replacing, the arc plate on the locking plate is squeezed by pressing the pressing post on the top of the clamping plate, thereby unlocking it and facilitating disassembly.

To ensure that the rack 201 can fit tightly against the toothed groove 203, a top post 204 is provided on the rear side of the rack 201. Under the pushing force of the spring 205, the top post 204 exerts a compressive force on the rack 201, thereby achieving a tight engagement between the rack 201 and the toothed groove 203. Elastic components are provided on the left and right sides of the rubber block 9. The elastic components include multiple springs 10, and the adjacent ends of the multiple springs 10 are fixedly connected to the rubber block 9. On the left and right sides of block 9, pressing the rack 201 backward can push the top column 204 to move relative to each other, thereby releasing the rack 201 from the tooth groove 203. Under the action of the spring 3 10 and the rubber block 9, the clamp 1 is unfolded for easy continued use later. Each adjacent side of the clamp 1 is fixedly connected with a sealing strip 4. The inner walls of the two sealing strips 4 are slidably connected to the outer wall of the rubber block 9. The sealing strips 4 are set on the outer wall of the rubber block 9 to effectively prevent blood from seeping into the clamp 1.

[0033] Reference Figure 2 , Figure 3 and Figure 5The replacement mechanism 3 includes two insertion slots 301, which are located on the front side of the clamping plate 1. Magnets 302 are fixedly connected to the inner walls of both insertion slots 301. Insertion plates 303 are slidably connected to the inner walls of both insertion slots 301. The insertion plates 303 are the same size as the insertion slots 301, allowing for precise insertion. The magnets 302 in the insertion slots 301 quickly attract the insertion plates 303 for rapid positioning and installation. Clamping plates 304 are fixedly connected to the front sides of the two insertion plates 303. The clamping plates 304 can be replaced according to actual needs, and their sizes vary to accommodate different sizes of blood vessels. Locking plates 305 are fixedly connected to the rear sides of both clamping plates 304. The front sides of the clamping plate 1 are... A locking groove 306 is provided. When the plug plate 303 is inserted into the plug groove 301, the locking plate 305 will be inserted into the locking groove 306. The locking plate 305 is locked by the arc plate at one end, ensuring the firmness of the clamping plate 304 during use. The top of the clamping plate 1 is slidably connected to the pressing post 307. The outer wall of the two pressing posts 307 is fixedly connected to the spring 308.

A lifting ring 8 is fixedly connected to the rear side of the outer wall of the welding point 7. The lifting ring 8 is fixed to the clamping plate 1 through the welding point 7, and the lifting ring 8 can be placed easily.

[0035] Working principle: First, the blood vessel is clamped by pressing the clamp 1. At this time, the rubber block 9 bends as the clamp 1 extends and retracts. At the same time, the right end of the rack 201 slides through the clamp 1 and is connected to the fixing box 202. The groove of the rack 201 and the tooth groove 203 fit together to lock. In order to ensure that the rack 201 can fit tightly on the tooth groove 203, the top column 204, under the pushing force of the spring 205, applies a squeezing force to the rack 201, thereby achieving a tight engagement between the rack 201 and the tooth groove 203, realizing the clamping control and adjustment of the clamp 1. Then, by pressing the rack 201 backward, the top column 204 can be pushed to move relative to each other, thereby releasing the engagement between the rack 201 and the tooth groove 203. Under the action of the spring 10 and the rubber block 9, the clamp 1 is unfolded for continued use later.

[0036] Furthermore, by precisely inserting the plug plate 303 into the plug slot 301, and quickly adsorbing the plug plate 303 with the magnet 302 in the plug slot 301, the plug plate 303 is quickly positioned and installed. When the plug plate 303 is inserted into the plug slot 301, the locking plate 305 will be inserted into the locking slot 306. The locking plate 305 is locked by the arc plate at one end, ensuring the firmness of the clamping plate 304 during use. When replacing, the arc plate on the locking plate 305 is squeezed by pressing the pressing post 307 on the top of the clamping plate 1, thereby unlocking it and facilitating disassembly. The clamping plate 304 can be replaced according to actual needs. The clamping plates 304 are of different sizes and can be used to clamp blood vessels of different sizes.
