Description

Technical Field

[0001] This utility model relates to the field of ligation and hemostasis clip technology, and in particular to a multi-angle adjustable ligation and hemostasis clip. Background Technology

[0002] Hemostatic clips are often used in surgical procedures to replace traditional sutures. They are used to ligate torn tissue within the incision to stop bleeding and improve surgical efficiency. Due to their ease of use and high operability, they are gradually being widely used in minimally invasive surgery, especially suitable for endoscopic surgeries such as laparoscopy and thoracoscopy where operating space and visibility are limited.

[0003] Chinese Patent Publication No. CN216675832U, published on 20220607, discloses an anti-lateral slippage hemostatic clip for tissue ligation or hemostasis. It includes a first clip arm and a second clip arm connected to each other, with their mating surfaces fitting together. The free end of the first clip arm has a hook, and the free end of the second clip arm has a locking head. When closed, the hook and locking head engage. Each mating surface of the first and second clip arms has multiple continuously distributed anti-slip teeth and multiple continuously distributed barbs. The anti-slip teeth and barbs are sequentially distributed along the direction from the free ends of the first and second clip arms to the connecting ends. The anti-slip teeth on the mating surface of the first and second clip arms are staggered and interlock with each other. The tips of the barbs on each mating surface face each other and are staggered.

[0004] Existing ligation hemostatic clips, such as those described above, use clamping parts on the outer sides of the upper and lower arms that match the internal grooves of the clamping forceps to ensure stable clamping of the hemostatic clip by the clamping forceps. In practice, the clamping parts are fixedly engaged with the hemostatic clip, and the orientation of the hemostatic clip is relatively fixed after the operator clamps it with the clamping forceps. It cannot be conveniently adjusted according to the position of the incision. Therefore, there is an urgent need to propose corresponding multi-angle adjustable ligation hemostatic clips to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a multi-angle adjustable ligation and hemostasis clip in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A multi-angle adjustable ligation and hemostasis clip includes a clip body, which includes an integrally formed upper arm and a lower arm. The open end of the upper arm is integrated with a locking head, and the open end of the lower arm is integrated with a locking hook. The locking head and the locking hook engage with each other. The outer sides of the upper arm and the lower arm are respectively provided with a locking seat one and a locking seat two, and a rotating component is provided between the upper arm and the locking seat one and between the lower arm and the locking seat two.

[0008] Preferably, the upper arm and the lower arm are respectively fixedly connected with upper convex teeth and lower convex teeth on their opposite surfaces, and the upper convex teeth and lower convex teeth are staggered.

[0009] Preferably, both sets of rotating components include fixed rods, the two sets of fixed rods are fixedly connected to the upper arm and the lower arm respectively, and the open ends of the two sets of fixed rods are rotatably connected to the inner surface of the locking seat one and the locking seat two respectively.

[0010] Preferably, both sets of fixed rods have convex rings fixedly connected to their open ends, and the two sets of convex rings are respectively rotatably engaged with the inner surface of the first and second locking seats through two sets of locking grooves.

[0011] Preferably, both the first and second card holders are hollowed out.

[0012] Preferably, both the first and second locking seats are cylindrical in shape.

[0013] Preferably, guide blocks are fixedly connected to both sides of the longitudinal end of the card head, and a pointed tip is provided on one side of the guide block.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0015] 1. In this application, locking seat one and locking seat two are locked in the grooves corresponding to the head of the clamp, so that the entire hemostatic clamp is positioned at the head of the clamp. The hemostatic clamp is moved as needed, and locking seat one and locking seat two remain engaged with the grooves. The two sets of fixing rods and protruding rings are respectively rotated and engaged with the inside of locking seat one and locking seat two until the hemostatic clamp is deflected to the appropriate orientation. The tissue to be clamped is placed in the hemostatic clamp, and the clamp is pressed by the clamp. The upper arm and lower arm move relative to each other, and the guide block penetrates the tissue first and guides it, so that the hook and the clamp head are quickly engaged. This completes the operation of the hemostatic clamp, thus maintaining the normal use of the hemostatic clamp while allowing the orientation of the hemostatic clamp to be conveniently adjusted as needed.

[0016] 2. In this application, after the hemostatic clip is fastened, the upper and lower convex teeth clamp together to prevent slippage, and the staggered distribution of the upper and lower convex teeth further prevents the hemostatic clip from detaching from the tissue or moving, enhancing the reliability of the grip and thus improving the stability of the hemostatic clip in use.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution:

[0025] A multi-angle adjustable ligation and hemostasis clip includes a hemostasis clip body, which includes an integrally formed upper arm 1 and a lower arm 2. The open end of the upper arm 1 is integrated with a locking head 6, and the open end of the lower arm 2 is integrated with a locking hook 5. The locking head 6 and the locking hook 5 are engaged. The outer sides of the upper arm 1 and the lower arm 2 are respectively provided with a locking seat 1 8 and a locking seat 2 9, and a rotating component is provided between the upper arm 1 and the locking seat 1 8 and between the lower arm 2 and the locking seat 2 9.

[0026] The locking seats 1 and 2 are engaged in the corresponding grooves on the head of the clamp, positioning the entire hemostatic clamp at the head of the clamp. As needed, the clamp is moved, and the locking seats 1 and 2 remain engaged with the grooves. The two sets of fixing rods 12 and the protruding rings 10 rotate and engage with the locking seats 1 and 2 respectively until the hemostatic clamp is deflected to the appropriate orientation. The tissue to be clamped is placed inside the hemostatic clamp, and the clamp is pressed by the clamp. The upper arm 1 and lower arm 2 move relative to each other, and the guide block 7 penetrates the tissue first and guides it, causing the hook 5 and the clamp head 6 to quickly engage, thus completing the operation of the hemostatic clamp. This ensures the normal use of the hemostatic clamp while allowing for convenient adjustment of its orientation as needed.

[0027] It should be noted that the clamping pliers and the corresponding grooves on the clamping pliers are existing technologies, so they will not be described in detail here.

[0028] Specifically, such as Figure 2 and Figure 4 As shown, the upper arm 1 and the lower arm 2 are respectively fixedly connected with upper convex teeth 3 and lower convex teeth 4 on their opposite surfaces. The upper convex teeth 3 and lower convex teeth 4 are staggered. After the hemostatic clip is engaged, it is clamped and prevented from slipping by the upper convex teeth 3 and lower convex teeth 4. The staggered distribution of the upper convex teeth 3 and lower convex teeth 4 further prevents the hemostatic clip from detaching from the tissue or moving, enhances the reliability of the grip, and thus improves the stability of the hemostatic clip in use.

[0029] Specifically, such as Figure 2 and Figure 3 As shown, both sets of rotating components include fixed rods 12. The two sets of fixed rods 12 are fixedly connected to the upper arm 1 and the lower arm 2, respectively. The open ends of the two sets of fixed rods 12 are rotatably connected to the inner walls of the locking seat 1 8 and the locking seat 2 9, respectively. The open ends of the two sets of fixed rods 12 are fixedly connected to protruding rings 10. The two sets of protruding rings 10 are rotatably engaged with the inner walls of the locking seat 1 8 and the locking seat 2 9 through two sets of locking grooves 11. The locking seat 1 8 and the locking seat 2 9 are locked in the corresponding grooves of the clamp head, so that the entire hemostatic clamp is positioned at the head of the clamp. The hemostatic clamp is moved as needed, and the locking seat 1 8 and the locking seat 2 9 remain engaged with the grooves. The two sets of fixed rods 12 and protruding rings 10 are rotatably engaged with the locking seat 1 8 and the locking seat 2 9, respectively, until the hemostatic clamp is deflected to the appropriate orientation.

[0030] Specifically, such as Figure 1 and Figure 2 As shown, both the first clamping seat 8 and the second clamping seat 9 have hollow interiors to ensure weight and reduce cost. Both the first clamping seat 8 and the second clamping seat 9 have cylindrical structures to fit the grooves on the clamping forceps, ensuring a stable connection between the first clamping seat 8 and the second clamping seat 9 and the clamping forceps head. Guide blocks 7 are fixedly connected to both sides of the longitudinal end of the clamping head 6, and one side of the guide block 7 is provided with a pointed tip. When the clamping forceps apply pressure to the hemostatic clamp, the upper arm 1 and the lower arm 2 move relative to each other. The guide block 7 first penetrates the tissue and guides, so that the hook 5 and the clamping head 6 can quickly engage.

[0031] Working principle: Clamping seats 1 (8) and 2 (9) are engaged in the corresponding grooves on the head of the clamping forceps, positioning the entire hemostatic clamp at the head of the forceps. As needed, the hemostatic clamp is moved, and clamping seats 1 (8) and 2 (9) remain engaged with the grooves. The two sets of fixing rods 12 and the protruding rings 10 rotate with the inside of clamping seats 1 (8) and 2 (9) respectively, until the hemostatic clamp deflects to the appropriate orientation. The tissue to be clamped is placed inside the hemostatic clamp, and the clamping forceps apply pressure to the clamp. Upper arm 1 and lower arm 2... In relative motion, the guide block 7 penetrates the tissue first and guides it, causing the hook 5 and the head 6 to snap together quickly, thus completing the operation of the hemostatic clip. This ensures the normal use of the hemostatic clip while allowing for convenient adjustment of its orientation as needed. After the hemostatic clip is snapped together, the upper convex teeth 3 and the lower convex teeth 4 clamp it tightly to prevent slippage. The staggered distribution of the upper convex teeth 3 and the lower convex teeth 4 further prevents the hemostatic clip from detaching from the tissue or moving, enhancing the reliability of the grip and thus improving the stability of the hemostatic clip in use.

[0032] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
