Abstract

This utility model relates to a stable ligation clip, including an upper clamping arm, a lower clamping arm, and a hinge. The rear ends of the upper and lower clamping arms are hinged together, and the front of both the upper and lower clamping arms is provided with a positioning post for cooperating with the clamping forceps. The front ends of the upper and lower clamping arms are also provided with a locking structure that cooperates with each other. The clamping surfaces of the upper and lower clamping arms are provided with several anti-slip textures. The rear side of the hinge is provided with a first structure to improve stable contact with the pushing plate of the clamping forceps. The addition of a first structure that can stably contact the pushing plate on the continuous-fire clamping forceps, while retaining the original ligation clip structure design, makes it compatible with both continuous-fire clamping forceps and currently available single-fire clamping forceps.

Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a ligation clip for stable application. Background Technology

[0002] In endoscopic minimally invasive surgery, before ligating blood vessels and other tissues, clipping is necessary to prevent bleeding and gastrointestinal leakage such as bile leakage. Currently, ligation clips on the market are mainly metal and plastic clips. Plastic clips are primarily made of polymer materials and are widely used due to their good biocompatibility, non-conductivity, and X-ray permeability. Ligation clips are generally used in conjunction with surgical instruments. The surgical instruments are used to grasp the ligation clip and close the blood vessel or tissue. The plastic clip is U-shaped with a locking device. Both ends of the ligation clip have grooves and barbs. During use, after the ligation clip completely wraps around the blood vessel or body cavity tissue, sufficient force is applied to the clip handle. The ligation clip closes under force, and the barbs slide into the grooves, ultimately permanently ligating and closing the blood vessel or body cavity tissue. The closure of the ligation clip is a crucial step in this process and is key to the success of the surgery.

[0003] Currently, with the development of technology, the required operation time is getting shorter and shorter. The clamping forceps have also gradually evolved from single clamps to multi-clamping forceps. Because multi-clamping forceps fix the ligation clips and realize the clamping process through a 3-point positioning method, through analysis of the multi-clamping clips on the market, we found that the ligation clips are prone to slipping off the clamping forceps during the clamping and clamping process. The main reason is that the ligation clips used in the current multi-clamping forceps are still the ligation clips used in the original single clamps, and their rear contours do not match the push plate of the clamping forceps. Utility Model Content

[0004] The purpose of this invention is to provide a stable ligation clip that can solve the problem of incompatibility between the continuous-fire clamp and the ligation clip mentioned in the background art.

[0005] This utility model is achieved through the following technical solution:

[0006] A ligation clip for stable application includes an upper clamping arm, a lower clamping arm, and a hinge. The rear ends of the upper clamping arm and the lower clamping arm are hinged to each other, and the front of the upper clamping arm and the lower clamping arm are provided with positioning posts for cooperating with the clamping forceps.

[0007] The front ends of the upper and lower clamping arms are also provided with a locking structure that cooperates with each other, and the clamping surfaces of the upper and lower clamping arms are provided with several anti-slip textures.

[0008] The rear side of the hinge is provided with a first structure to improve stable contact with the push plate of the clamping pliers.

[0009] Compared with previous technologies, the beneficial effects of this utility model are as follows:

[0010] 1. This utility model adds a limiting slot structure that can cooperate with the pushing plate on the continuous-fire clamp, while retaining the original ligation clip structure design. It is compatible with both continuous-fire clamps and single-fire clamps currently on the market. Moreover, the clamping is stable and the operating principle is the same, so doctors do not need to readjust.

[0011] 2. When this ligation clip is used in conjunction with the continuous clamping clamp, the two sets of positioning pins and the limiting slot structure form a three-point positioning structure, which makes the clamping and clamping processes of the continuous clamping clamp very stable.

[0012] 3. The ribs on the left and right sides of the limiting slot form a structure similar to reinforcing ribs. After adding the limiting slot, the strength of the hinge can be guaranteed by adding ribs, and the strength will not be weakened.

[0013] 4. This utility model also incorporates a wing plate, which increases the width of the rear side of the hinge, significantly preventing the ligation clamp from slipping off the push plate of the clamping clamp. Attached Figure Description

[0018] The present invention will now be described in detail with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description:

[0019] like Figure 1-3 As shown, a ligation clip for stable clamping includes an upper clamping arm 3, a lower clamping arm 4, and a hinge 5. The rear ends of the upper clamping arm 3 and the lower clamping arm 4 are hinged to each other through the hinge 5, and the front of the upper clamping arm 3 and the lower clamping arm 4 are provided with positioning pins 2 for cooperating with the clamping clamp.

[0020] The front ends of the upper clamping arm 3 and the lower clamping arm 4 are also provided with a locking structure that cooperates with each other, and the clamping surfaces of the upper clamping arm 3 and the lower clamping arm 4 are provided with a number of anti-slip textures 8.

[0021] The rear side of the hinge is provided with a first structure to improve stable contact with the push plate of the clamping pliers.

[0022] Based on its differences, the first structure has the following two embodiments:

[0023] Example 1

[0024] like Figure 1 As shown: The first structure is a limiting groove 6 located in the middle of the rear side of the hinge 5 and cooperating with the contour of the push plate of the clamping pliers.

[0025] This invention adds a limiting groove structure that engages with the pushing plate on the continuous-fire clamp, while retaining the original ligation clip design. It is compatible with both continuous-fire clamps and currently available single-fire clamps, offering stable clamping and operating on the same principle, eliminating the need for doctors to readjust. When used with the continuous-fire clamp, the two sets of positioning posts and the limiting groove structure form a three-point positioning system, ensuring high stability during both the clamping and release processes.

[0026] Furthermore, the left and right sides of the limiting slot 6 are provided with ribs 9, and the upper and lower ends of any rib 9 extend towards the upper clamping arm 3 and the lower clamping arm 4 respectively, so that a strip-shaped groove 91 containing the limiting slot 6 is formed between the two ribs.

[0027] The ribs on both sides of the limiting slot form a structure similar to reinforcing ribs. After adding the limiting slot, the strength of the hinge can be guaranteed by adding ribs, and the strength will not be weakened.

[0028] Example 2

[0029] like Figure 2 As shown: The first structure is a wing plate 6A located on the rear side of the hinge 5 and extending to the left and right. The wing plate increases the width of the rear side of the hinge, which greatly prevents the ligation clamp from slipping off the push plate of the clamping clamp.

[0030] Based on the above embodiments, the locking structure includes a locking hook 1 provided at the front end of the upper clamping arm 3 and a locking buckle 7 provided at the front end of the lower clamping arm 4;

[0031] The locking hook 1 and the locking buckle 7 are connected in a cooperative manner.

[0032] It should be noted that the structure of the latch 7 and the hook 1 is a conventional technical method, so it will not be described in detail.

[0033] In use, the two positioning posts 2 are a conventional technique, allowing the ligation clip 10 to connect with commonly available single-shot clamps. The limiting groove 6 added to the hinge 5 forms a three-point positioning system with the two positioning posts 2, enabling it to engage with the novel multi-shot clamp. For example... Figure 3 As shown, the two positioning posts 2 are respectively connected to the upper clamp 11 and lower clamp 12 of the rapid-fire clamping pliers, while the limiting slot 6 is connected to the pushing piece 13 of the rapid-fire clamping pliers, forming a stable three-point positioning to drive the clamping. The limiting slot 6 can fix and restrict the pushing piece 13 of the rapid-fire clamping pliers during this process, preventing the pushing piece from slipping and failing to clamp during clamping or application. The rib 9 allows the hinge of this invention to maintain its structural strength even with the limiting slot.

[0034] During surgery, when entering the abdominal cavity, a certain force is applied to the handle of the continuous or single-shot clamp equipped with the ligation clamp 10 of this utility model, so that the ligation clamp 10 is slightly closed (not closed), and then the loaded clamp is inserted into the place in the body where clamping is required through the trocar or other channels.

[0035] During the clamping process, after ensuring a clear view of the ligated blood vessel and the surrounding body cavity tissue, insert it into the occlusal surface of the ligation clip 10, and then grip the handle of the continuous or single clamping forceps to the bottom so that the occlusal surface of the ligation clip closes and the ligation clip is locked.

[0036] Although this utility model has been illustrated and described using specific embodiments and alternative methods, it should be understood that various changes and modifications are permitted as long as they do not depart from the spirit and scope of this utility model. Therefore, it should be understood that this utility model is not limited in any sense except by the appended claims and their equivalents.
