Description

Technical Field

[0001] This invention belongs to the field of medical device technology, and more specifically, relates to a punctureable ligation clip and an application device for holding the punctureable ligation clip. Background Technology

[0002] Ligation clips are suitable for ligating blood vessels or other tubular structures in clinical laparoscopic surgery or surgical non-absorbable ligation clips, thereby helping medical staff to quickly ligate during surgery without manual ligation; traditional ligation clips can effectively ligate thinner tissues and vascular structures.

[0003] During surgical procedures, to fully expose the surgical field, it is necessary to ligate the blood vessels surrounding the target tissue to stop bleeding. Hemostasis has become one of the core basic surgical techniques. Almost every surgical procedure on any part of the human body involves bleeding and hemostasis, and generally, a clamping device is used to ligate and close the wound to stop the bleeding. However, when encountering thicker fascia and skin tissue, traditional ligation clips cannot effectively penetrate the tissue to merge or close, thus failing to effectively ligate at that location. This often results in clip slippage and incomplete clamping, which increases the body's rejection and resource consumption, and has a certain impact on surgical resection.

[0004] Therefore, there is an urgent need to design a ligation clip structure that can solve the above-mentioned technical problems. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the purpose of this invention is to provide a punctureable ligation clip that has reliable clamping, can puncture thicker tissues, and can avoid the occurrence of false clamping accidents.

[0006] To solve the above-mentioned technical problems or achieve the above-mentioned objectives, the present invention adopts the following technical solution: According to one aspect of the present invention, a punctureable ligation clip is provided, comprising: Connecting part; The upper arm and the lower arm are connected by a connecting part to form a V-shaped structure, and the opposite sides of the upper arm and the lower arm respectively form a clamping surface; An arrow-shaped component protrudes from the end of the upper arm away from the connecting part toward the lower arm. The arrow-shaped component has barbs and a needle tip at the bottom. A locking component is provided on the lower arm, and when the upper arm and lower arm are clamped together, the arrow-shaped component is inserted and locked.

[0007] In one embodiment of the present invention, the puncturable ligation clip further includes: The first limiting post is located at the top of the end of the upper arm away from the connecting part and is opposite to the arrow-shaped component. The first limiting post is provided with a guide hole for inserting a steel needle into the arrow-shaped component. The second limiting post is located at the bottom of the locking component.

[0009] In one embodiment of the present invention, different textures may be provided on both the upper locking boss and the lower locking boss.

[0010] In one embodiment of the present invention, the locking component includes an inner tooth groove and a stop edge located on both sides of the groove opening of the inner tooth groove. The inner tooth groove engages with the reverse teeth of the arrow-shaped component, and the stop edge prevents the arrow-shaped component from moving outward after it enters the inner tooth groove.

[0011] In one embodiment of the present invention, both the upper arm and the lower arm are arc-shaped structures.

[0012] In one embodiment of the present invention, an elastic groove that can open and close elastically is provided at the bend of the connecting part.

[0013] In one embodiment of the present invention, both the upper arm and the lower arm are planar structures.

[0014] In one embodiment of the present invention, the bend of the connecting part is provided as an elastically opening and closing arc-shaped structure, and a limiting rib extends inward from one end of the inner side of the arc-shaped structure.

[0015] In one embodiment of the invention, the reverse teeth are arranged in different layers or depths.

[0016] According to another aspect of the present invention, a clamping device is provided, comprising a clamping device body and a clamping head assembly disposed at the front end of the clamping device body, the clamping head assembly clamping a punctureable ligation clip as described above, and the clamping head assembly comprising: The upper clamp head has a first positioning groove and a steel needle at the bottom of its front end.

Detailed Implementation

[0023] To better understand the above-described objectives, features, and advantages of this disclosure, embodiments of this disclosure will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0024] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways than those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0025] like Figure 1-4 As shown, an embodiment of the present invention provides a puncturable ligation clip, comprising: an upper arm 1, a lower arm 14, a connecting portion 10, an arrow-shaped component 13, and a locking component 12. The upper arm 1 and the lower arm 14 are connected by the connecting portion 10 to form a V-shaped structure, and clamping surfaces are formed on opposite sides of the upper arm 1 and the lower arm 14, respectively. The arrow-shaped component 13 protrudes from the end of the upper arm 1 away from the connecting portion 10 toward the lower arm 14, and has barbs 2 on its surface and a needle tip 3 at its bottom. The locking component 12 is disposed on the lower arm 14, and when the upper arm 1 and the lower arm 14 are clamped, the arrow-shaped component 13 is inserted and locked. Compared to traditional ligation clips, the puncture-capable ligation clip of the above embodiments of the present invention features a structure with inverted teeth 2 and a needle tip 3, enabling it to puncture thicker tissues and ensuring that the ligation clip does not slip and effectively closes or shuts. The inverted teeth 2, in conjunction with the locking component 12 on the lower arm 14, provide positioning and better lock the ligation clip. The built-in needle tip design of the puncture-capable ligation clip of the above embodiments of the present invention utilizes the rigidity of its material, allowing the needle-like structure to effectively penetrate tissue. Preferably, the needle tip can be made of a composite material, which has excellent rigidity and can effectively penetrate thicker tissues.

[0026] In the puncturable ligation clip shown in the above embodiments of the present invention, refer again... Figure 1-3 The puncture-compatible ligation clip also includes: a first limiting post 6 and a second limiting post 11. The first limiting post 6 is located at the top of the end of the upper arm 1 away from the connecting part 10 and is opposite to the arrow-shaped component 13. The first limiting post 6 is provided with a guide hole 20 for inserting the steel needle 16 into the arrow-shaped component 13 (specifically as shown in the figure). Figure 2 (As shown). The second limiting post 11 is located on the bottom of the locking component 12. The first limiting post 6 and the second limiting post 11 can be positioned on the clamping device, which facilitates operation.

[0027] In the puncturable ligation clip shown in the above embodiments of the present invention, refer again... Figure 1-3The puncture-compatible ligation clip also includes multiple upper locking protrusions 21 and multiple lower locking protrusions 22. The upper locking protrusions 21 are disposed on the clamping surface of the upper arm 1, and the lower locking protrusions 22 are disposed on the clamping surface of the lower arm 14, with the upper locking protrusions 21 and lower locking protrusions 22 being staggered. The structural position of the upper locking protrusions 21 and lower locking protrusions 22 is very important; their staggered structure allows for tighter closure of the tissue, avoiding the phenomenon of incomplete clamping. Figure 3-4 The diagram shows the closed state of the ligation clip.

[0028] In the puncturable ligation clip shown in the above embodiments of the present invention, both the upper locking protrusion 21 and the lower locking protrusion 22 can be provided with different textures. The different textures on the upper locking protrusion 21 and the lower locking protrusion 22 increase friction and better close the tissue.

[0029] In the puncturable ligation clip shown in the above embodiments of the present invention, refer again... Figure 1-3 The locking component 12 includes an inner toothed groove 5 and baffles 4 located on both sides of the groove opening of the inner toothed groove 5. The inner toothed groove 5 engages with the reverse teeth 2 of the arrow-shaped component 13. The baffles 4 prevent the arrow-shaped component 13 from moving outward after it enters the inner toothed groove 5. The baffles 4 are installed at the groove opening of the inner toothed groove 5 that engages with the lower arm 14. This engagement with the reverse teeth 2 provides a positioning function and better locks the ligation clip.

[0030] In the puncturable ligation clip shown in the above embodiments of the present invention, refer again... Figure 1-3 Both the upper arm 1 and the lower arm 14 are arc-shaped structures. Compared to the tissue, this design allows for better closure of the ligation clip while also providing a certain degree of elasticity.

[0031] In the puncturable ligation clip shown in the above embodiments of the present invention, refer again... Figure 1-3 The connecting part 10 has an elastically opening and closing slot 7 at the bend. The elastic slot 7 is a hinge structure with elastic opening and closing of the ligation clip, which can effectively absorb and release the clamping force, while ensuring that the upper arm 1 and the lower arm 14 fit more tightly and ensure the airtightness of the ligation clip.

[0032] In the puncturable ligation clip shown in the above embodiments of the present invention, preferably, the inverted teeth 2 are arranged in different layers or at different depths. The inverted teeth 2 are divided into several layers or have different depths, which can adapt to tissues of different thicknesses and ensure effective closure of the upper arm 1 and lower arm 14 of the ligation clip.

[0033] like Figure 5-6As shown, an embodiment of the present invention provides a clamping device, including a clamping device body 23 and a clamping head assembly 24 disposed at the front end of the clamping device body 23. The clamping head assembly 24 clamps the punctureable ligation clip as described above, and the clamping head assembly 24 includes an upper clamping head 8 and a lower clamping head 9. The bottom of the front end of the upper clamping head 8 is provided with a first positioning groove 17 and a steel needle 16. The first positioning groove 17 is engaged with the first limiting post 6 of the punctureable ligation clip. The steel needle 16 is inserted into the arrow-shaped component 13 through the guide hole 20 on the first limiting post 6. The clamping surface of the upper clamping head 8 is configured as an upper groove 15, and the steel needle 16 is disposed at the front end of the upper groove 15. The above embodiment of the present invention is a ligation clip with a hole. A steel needle 16 is provided on the clamping device, which can pass through the upper arm 1 of the ligation clip. This makes the puncture effect of the steel needle 16 better, and it can penetrate thicker tissue. It is locked with the back teeth 2. The top of the front end of the lower clamp head 9 is provided with a second positioning groove 18, which engages with the second limiting post 11 of the puncture ligation clip. The clamping surface of the lower clamp head 9 is set in the form of a lower groove 19.

[0034] Refer again Figure 5 The most significant feature of the clamping device shown in the above embodiments of the present invention is that a steel needle 16 is provided at the end of the upper groove 15, which can effectively puncture thicker tissues. The upper groove 15 and the lower groove 19 are designed to limit the ligation clip. The first positioning groove 17 and the second positioning groove 18 can position the ligation clip and act as a pivot, allowing for adjustment of the direction after rotation to better close the ligation clip. At the same time, the upper clamp head 8 and the lower clamp head 9 at the front end of the clamping device body 23 open and close along the pivot at the rear. The clamping device body 23 can be a handle of an open surgical scissors structure or a slender rod structure for minimally invasive surgery.

[0035] Figure 7 A schematic diagram of a punctureable ligation clip according to another embodiment of the present invention is shown. Figure 7 As shown, in this embodiment, the overall structure of the puncture-ligation clip is similar to... Figure 1 Similar to the puncture-ligating clip shown, the difference lies in that both the upper arm 1 and the lower arm 14 are planar structures. The bend in the connecting part is designed as an elastically opening and closing arc-shaped structure 25, and one end of the arc-shaped structure 25 extends inward to form a limiting rib 26. The upper arm 1 and the lower arm 14 are planar structures, the bend is arc-shaped, and it has an elastic opening and closing structure. At the same time, the limiting rib 26 can limit the tissue and ensure the effective length of closure.

[0036] Therefore, the puncture ligation clip of the present invention is firm and reliable when clamped, can puncture thicker tissues, and can avoid slippage and false clamping accidents.
