Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a disposable microvascular clip. Background Art

[0002] Vascular clips are medical instruments often used by doctors during surgeries to clamp blood vessels and prevent blood from flowing out of the severed blood vessels. The clamping of blood vessels by vascular clips is crucial. If the clamping force is too large or unstable, it is likely to damage the vascular wall tissue and intima during use, resulting in the formation of blood clots. If the clamping force is too small or uneven, blood leakage is likely to occur.

[0003] In the existing disposable microvascular clips, due to the excessive smoothness of the plasma outside the blood vessels, the vascular clips are likely to shift and fall off, causing the vascular clips to be unable to clamp the blood vessels, thus posing a medical risk. Therefore, a disposable microvascular clip is proposed to solve the above-mentioned problems. Summary of the Utility Model

[0004] (1) Technical Problems to be Solved

[0005] Aiming at the deficiencies of the prior art, the utility model provides a disposable microvascular clip, which has the advantages of preventing the vascular clip from shifting and falling off on the outside of the blood vessel, and solves the problem that the excessive smoothness of the plasma outside the blood vessel easily causes the vascular clip to shift and fall off, resulting in the vascular clip being unable to clamp the blood vessel, thus posing a medical risk.

[0006] (2) Technical Solutions

[0007] The technical solution adopted by the utility model to solve the above technical problems is as follows: A disposable microvascular clip includes clamping plates, a rotating handle is fixedly connected to the rear side of the clamping plates, the upper rotating handle is rotatably connected to the lower rotating handle, connecting blocks are fixedly connected to the rear sides of both rotating handles, a same spring is fixedly connected to the relative inner sides of the two connecting blocks, and limiting blocks distributed in a staggered manner are fixedly connected to the relative inner sides of both clamping plates.

[0008] The beneficial effects of the utility model are as follows:

[0009] This disposable microvascular clip has the advantages of limiting the clamped blood vessel and preventing the vascular clip from deviating from its original position or separating from the outside of the blood vessel.

[0010] Based on the above technical solutions, the utility model can be further improved as follows.

[0011] Further, tooth marks are provided on the relative inner sides of the two clamping plates.

[0012] The beneficial effect of adopting the above further solution is that the friction between the blood vessel and the splint is increased, preventing the blood vessel from slipping off the inner side of the splint 1, thereby avoiding medical accidents.

[0013] Furthermore, a rotating column is fixedly connected inside the upper side of the rotary handle, and the outer side of the rotating column is rotatably connected to the lower side of the rotary handle.

[0014] Furthermore, the distance between the two splints in the normal state is smaller than the diameter of the blood vessel.

[0015] The beneficial effect of adopting the above further solution is that the splints in the blood vessel clamp can clamp the blood vessel, and it will not fail to fix due to the too small diameter of the blood vessel.

[0016] Furthermore, the connecting block is semi-circular.

[0017] Furthermore, a clamping groove is formed inside the connecting block.

[0018] The beneficial effect of adopting the above further solution is that with the help of a tool to control the blood vessel clamp and press the connecting block, the blood vessel can be clamped. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] In the embodiment, by Figures 1-4Provided is a disposable microvascular clip. The utility model includes a splint 1, a rotating handle 2 is fixedly connected to the rear side of the splint 1, the upper rotating handle 2 is rotatably connected to the lower rotating handle 2, connecting blocks 3 are fixedly connected to the rear sides of the two rotating handles 2, the same spring 4 is fixedly connected to the relative inner sides of the two connecting blocks 3, and limiting blocks 5 distributed in a staggered manner are fixedly connected to the relative inner sides of the two splints 1.

[0026] Press the connecting block 3 towards the relative inner side, the connecting block 3 drives the spring 4 to compress, the connecting block 3 drives the rotating handle 2 to rotate, the rotating handle 2 drives the splint 1 to rotate, so that the two splints 1 move away from each other, place the blood vessel on the relative inner sides of the two limiting blocks 5, release the connecting block 3, the spring 4 resumes, the connecting block 3 drives the rotating handle 2 to reset, and the rotating handle 2 drives the splint 1 to move towards the outer side of the blood vessel, so that the blood vessel is fixed between the two limiting blocks 5 and is not likely to fall off.

[0027] Specifically, referring to Figure 4 , tooth marks 6 are formed on the relative inner sides of the two splints 1.

[0028] In this embodiment, the friction between the blood vessel and the splint 1 is increased to prevent the blood vessel from slipping off the inner side of the splint 1, thereby causing a medical accident.

[0029] Specifically, referring to Figure 1 , a rotating column 7 is fixedly connected to the inside of the upper rotating handle 2, and the outer side of the rotating column 7 is rotatably connected to the lower rotating handle 2.

[0030] In this embodiment, the rotating column 7 enables the two rotating handles 2 to rotate relative to each other without falling off, so that the blood vessel clip can clamp the blood vessel.

[0031] Specifically, referring to Figure 1 , the distance between the two splints 1 in the normal state is smaller than the diameter of the blood vessel.

[0032] In this embodiment, the splints in the blood vessel clip can clamp the blood vessel and will not fail to fix due to the too small diameter of the blood vessel.

[0033] Specifically, referring to Figure 3 , the connecting block 3 is semi-circular.

[0034] In this embodiment, it is convenient to press the connecting block 3, so that the rotating handle 2 drives the splint 1 to rotate to clamp the blood vessel.

[0035] Specifically, referring to Figure 3 , a clamping groove 8 is formed in the inside of the connecting block 3.

[0036] In this embodiment, it is possible to control the blood vessel clip with the aid of a tool, press the connecting block 3, and thus clamp the blood vessel.

[0037] Working principle:

[0038] First: Press the connecting block 3 towards the relatively inner side. The connecting block 3 drives the spring 4 to compress. The connecting block 3 drives the rotary handle 2 to rotate. The rotary handle 2 drives the clamping plate 1 to rotate, causing the two clamping plates 1 to move away from each other. Place the blood vessel on the relatively inner side of the two limiting blocks 5, and release the connecting block 3. The spring 4 resumes its shape.

[0039] Then: The connecting block 3 drives the rotary handle 2 to reset. The rotary handle 2 drives the clamping plate 1 to move towards the outer side of the blood vessel, fixing the blood vessel between the two limiting blocks 5 and preventing it from falling off easily.
