Description

Technical Field

[0001] The utility model relates to the field of medical appliances, in particular to a cerebrovascular anastomosis clip. Background Art

[0002] In various surgical operations, such as cerebrovascular surgery, blood vessel anastomosis is a necessary operation item. Briefly speaking, blood vessel anastomosis is to suture blood vessels. When performing a blood vessel anastomosis operation, a blood vessel anastomosis clip is needed to clamp and control the thread. However, due to the small size of the blood vessel anastomosis clip, a clamp is also needed to clamp and fix the blood vessel anastomosis clip during the operation.

[0003] When the traditional clamp clamps the blood vessel anastomosis clip, if it relies solely on the clamping force and friction for connection, it is very easy for the blood vessel anastomosis clip to slide relative to the clamp, and even cause the blood vessel anastomosis clip to fall off, which affects the safety of the surgical staff. Therefore, a cerebrovascular anastomosis clip is proposed to solve the above problems. Summary of the Utility Model

[0004] (I) Technical Problems to be Solved

[0005] In view of the deficiencies of the prior art, the utility model provides a cerebrovascular anastomosis clip, which has the advantages of stable fixation between the clamp and the blood vessel anastomosis clip and not being easily detached, and solves the problem that when the traditional clamp clamps the blood vessel anastomosis clip, if it relies solely on the clamping force and friction for connection, it is very easy for the blood vessel anastomosis clip to slide relative to the clamp, and even cause the blood vessel anastomosis clip to fall off, which affects the safety of the surgical staff.

The anastomosis clip includes two connecting frames. Clamping plates are fixedly connected to the outer sides of the two connecting frames.

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

[0009] This cerebrovascular anastomosis clip has the advantages of stable fixation between the clamp and the blood vessel anastomosis clip and not being easily detached.

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

[0011] Further, threaded grooves are provided inside both of the two limiting sleeves, and the two limiting sleeves are respectively threadedly connected to the two limiting rods. The two limiting sleeves are connected to each other by a rope.

[0017] Further, the two pressing devices include bolt knobs respectively threadedly connected to the interiors of the two protective frames. Pressing plates that are slidably connected to the protective frames are rotatably connected to the opposite sides of the two bolt knobs.

[0018] The beneficial effect of adopting the above further solution is that the pressing plate can be moved, so that the pressing plate can restrict the connecting frame and keep the connecting frame fixed.

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying 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 making creative efforts belong to the scope of protection of the present utility model.

[0027] In the embodiment, given by Figures 1-4 There is provided a cerebrovascular anastomosis clip. The present utility model includes clamping forceps 1. The clamping forceps 1 includes two forceps arms 11 that are rotatably connected. Handles 12 are provided on the outer sides of the two forceps arms 11. Limiting rods 14 are fixedly connected to the opposite sides of the two forceps arms 11. Limiting sleeves 13 are provided on the outer sides of the two limiting rods 14. Protective frames 2 are fixedly connected to the opposite sides of the two forceps arms 11. Pressing devices 3 are provided inside the two protective frames 2. Limiting plates 5 are fixedly connected to the front and rear walls inside the two protective frames 2. Anastomosis clips 4 are slidably connected inside the two protective frames 2. The anastomosis clip 4 includes two connecting frames 41. Splints 42 are fixedly connected to the outer sides of the two connecting frames 41.

[0028] Among them, threaded grooves are provided inside the two limiting sleeves 13. The two limiting sleeves 13 are respectively threadedly connected to the two limiting rods 14. The two limiting sleeves 13 are connected to each other by a rope.

[0029] In this embodiment, during actual use, by the threaded rotation of the limiting rod 14 and the limiting sleeve 13, the distance between the two limiting sleeves 13 can be controlled. Under the pulling of the rope, the opening angle of the two forceps arms 11 is affected, and further the opening angle of the anastomosis clip 4 is affected, preventing the opening angle of the anastomosis clip 4 from being too large and causing material damage and affecting the clamping force.

[0030] Among them, the outer edges of the two splints 42 are both arc-shaped. Anti-slip grooves are provided on the opposite surfaces of the two splints 42.

[0031] In this embodiment, during actual use, during the suture of blood vessels, the splint 42 with an arc-shaped edge is less likely to scratch the blood vessels, and the anti-slip grooves of the splint 42 mesh with each other, making the clamping of the sewing thread by the splint 42 more stable.

[0032] Among them, two U-shaped grooves are respectively formed inside the two connecting frames 41, and the two U-shaped grooves are symmetrically distributed front and back and are respectively slidably connected to the four limiting plates 5, and anti-slip grooves are provided on the opposite sides of the two connecting frames 41.

[0033] In this embodiment, during actual use, the U-shaped frame in the connecting frame 41 is aligned and placed along the limiting plate 5. The connecting frame 41 and the protective frame 2 are not easy to move in the horizontal direction and can only slide in the vertical direction. The U-shaped groove limits the moving direction of the limiting plate 5 embedded therein, and the anti-slip groove can increase the friction force.

[0034] Among them, the two pressing devices 3 include bolt knobs 31 respectively threadedly connected to the interiors of the two protective frames 2, and pressing plates 32 rotatably connected to the opposite sides of the two bolt knobs 31 and slidably connected to the protective frames 2 are provided.

[0035] In this embodiment, during actual use, when the bolt knob 31 is turned, the pressing plate 32 will move and make contact with the outer side surface of the connecting frame 41 that slides into it.

[0036] Among them, anti-slip plates 6 are provided on the opposite surfaces of the two pressing plates 32, two limiting grooves are respectively formed inside the two protective frames 2 and are distributed front and back, and fixing rods 7 respectively slidably connected to the four limiting grooves are fixedly connected to the front and rear sides of the two pressing plates 32.

[0037] In this embodiment, during actual use, the meshing of the anti-slip plate 6 and the anti-slip groove makes the contact between the pressing plate 32 and the connecting frame 41 more stable, and the movement of the fixing rod 7 in the limiting groove limits the moving direction of the pressing plate 32.

[0038] Working principle:

[0039] First, the anastomosis clip 4 is placed between the two protective frames 2, and through the sliding of the U-shaped groove in the connecting frame 41 and the limiting plate 5, the anastomosis clip 4 is preliminarily limited. Subsequently, the bolt knob 31 is turned to make the pressing plate 32 press and fix the connecting frame 41. The combination of the anti-slip plate 6 and the anti-slip groove makes its fixation more stable and not prone to relative sliding. Rotating the two limiting sleeves 13 can adjust the pulling length of the rope between them, so that the opening angle of the two clamping arms 11 is limited, and the two limiting rods 14 limit the closing angle of the two clamping arms 11, so as to standardize the opening and closing angles of the anastomosis clip 4 and prevent excessive force from damaging the suture thread and blood vessels.
