Description

Technical Field

[0001] The present application relates to the technical field of hemostatic clip accessories, and in particular to an open connecting piece for a hemostatic clip. Background Art

[0002] With the continuous advancement of minimally invasive endoscopic techniques, cutting-edge endoscopic treatments such as ESD, POEM, and STER have rapidly expanded and matured. Hemostatic clips play a crucial role in these treatments, though they are almost exclusively used for tissue closure and hemostasis.

[0003] Endoscopic hemostatic clipping involves inserting a metal clip through the endoscope into the surgical site and directly clamping visible bleeding points and wound surfaces. Hemostasis is achieved primarily by clamping the blood vessels or surrounding tissues. After the clip stops bleeding, the local tissue reassembles and then falls off spontaneously, passing through the digestive tract. This procedure offers the advantages of minimal trauma, rapid hemostasis, and a low probability of rebleeding.

[0004] However, the existing hemostatic clamp has a risk of breaking at the connection between the internal connecting piece and the clip after the clip is closed and released, and even some fragments break directly and remain in the patient's body, increasing the risk of surgery and patient discomfort. Therefore, it is necessary to provide an open connecting piece for a hemostatic clamp to solve the above problems.

[0005] It should be noted that the above information disclosed in this Background section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Summary of the Invention

[0006] Based on the above problems existing in the prior art, the problem to be solved by this application is: to provide an open connecting piece for a hemostatic clip, which can prevent the connecting piece from breaking and prevent fragments from breaking and falling into the patient's body, thereby reducing the risk of surgery and the patient's discomfort.

[0007] The technical solution adopted by the present application to solve the technical problem is: an open connecting piece for a hemostatic clip, comprising:

[0008] core rod;

[0009] A slip ring, one end of which is provided with a booster tube, wherein the booster tube and the slip ring are slidably connected to the core rod;

[0010] a nut, the nut being rotatably connected to the other end of the core rod, and an outer tube being fixedly mounted on an end of the nut away from the core rod;

[0011] a fixing sleeve mounted on the other end of the outer tube;

[0012] A cable is crimped into the booster tube.

[0013] The other end of the cable is provided with a connecting piece, and the end of the connecting piece away from the cable is provided with two sets of arc pieces arranged opposite to each other, with an opening left between the two sets of arc pieces;

[0014] The jacket has two groups of hinged clips arranged inside it, and nail rods are installed at the connecting ends of the two groups of clips, and the arc pieces are clamped on the nail rods.

[0015] Furthermore, a convex ring is fixedly installed on one end of the fixing sleeve, and the convex ring cooperates with the sleeve. A hole is penetrated through the convex ring, and a waist groove is penetrated through the end of the sleeve close to the fixing sleeve, and the waist groove and the hole correspond to each other.

[0016] Furthermore, a limiting pull rod is provided for internal sliding of the fixing sleeve and the outer tube, and the limiting pull rod is located on one side of the connecting piece. One end of the limiting pull rod is fixedly installed with a hanging angle outward, and the hanging angle cooperates with the hole and the waist groove.

[0017] Furthermore, an interference ring is fixedly installed on one end of the limiting pull rod, and the limiting pull rod is configured to be U-shaped and elastic.

[0018] Furthermore, the opening between the arc pieces is smaller than the diameter of the nail rod.

[0019] The beneficial effects of the present application are as follows: the present application provides an open connecting piece for a hemostatic clamp. During operation, the slip ring is manually pulled outward, causing the booster tube and the pull cable to move accordingly, and the clamp is pulled into the clamp sleeve until the clamp is closed and locked to complete the clamping operation. The operator then continues to apply force to pull the connecting piece outward, causing the arc piece to deform and open outward, and separate from the nail rod, thereby preventing the connecting piece from breaking and preventing fragments from breaking and being left in the patient's body, reducing the risk of surgery and the patient's discomfort.

[0020] In addition to the above-described purposes, features and advantages, the present application also has other purposes, features and advantages. The present application will be further described in detail below with reference to the drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0030] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0031] like Figure 1-Figure 2 As shown, the present application provides an open connecting piece for a hemostatic clip, comprising a core rod 1, which is composed of a finger ring and a cross bar. A slip ring 2 is slidably connected to the core rod 1, and a booster tube 3 is fixedly installed on the end of the slip ring 2 away from the finger ring of the core rod 1. The booster tube 3 is also slidably connected to the core rod 1 and moves together with the slip ring 2. The other end of the core rod 1 is rotatably connected to a nut 4, so that by holding the nut 4, the core rod 1 can rotate freely axially and limit the sliding of the slip ring 2;

[0032] At the same time, the outer tube 5 is fixedly installed on one end of the nut 4 away from the core rod 1, and the other end of the outer tube 5 is welded and fixed with a fixing sleeve 6, and a cable 9 is crimped inside the booster tube 3. The cable 9 passes through the nut 4 and is located inside the outer tube 5, and the other end of the cable 9 is fixedly installed with a connecting piece 13. Figure 5As shown, two sets of oppositely arranged arc pieces 131 are fixedly mounted on one end of the connecting piece 13 away from the cable 9 , with openings left between the arc pieces 131 . The connecting ends of the arc pieces 131 and the connecting piece 13 can be slightly deformed.

[0033] like Figure 2-Figure 4 As shown, a jacket 7 is provided on the other side of the fixed sleeve 6, and two groups of hinged clips 8 are provided inside the jacket 7. The hinges of the two groups of clips 8 are provided with torsion springs (not shown in the figure). The torsion springs can make the two groups of clips 8 move away from the jacket 7 and open. At the same time, a nail rod 14 is fixedly installed at the connecting end of the two groups of clips 8. By moving the nail rod 14, the clips 8 can slide in the jacket 7 to achieve the opening and closing effect.

[0034] In this application, the arc piece 131 on the connecting piece 13 is normally stuck on the nail rod 14, and the opening between the arc pieces 131 is smaller than the diameter of the nail rod 14. Therefore, when the operator pulls the slip ring 2, the booster tube 3 can drive the cable 9 to move the connecting piece 13 and the nail rod 14 at the same time, so that the clamp 8 moves into the sleeve 7 and closes and locks.

[0035] In order to fix the jacket 7 on the fixed sleeve 6, a convex ring 61 is fixedly installed on one end of the fixed sleeve 6. The convex ring 61 cooperates with the jacket 7, and a hole 62 is formed through the convex ring 61. At the same time, a waist groove 71 is formed through the end of the jacket 7 close to the fixed sleeve 6. It should be noted that when the jacket 7 is sleeved on the convex ring 61, the waist groove 71 and the hole 62 correspond to each other.

[0036] At the same time, a limiting pull rod 12 is slidingly arranged inside the fixed sleeve 6 and the outer tube 5. The limiting pull rod 12 is located on one side of the connecting piece 13. The limiting pull rod 12 is set to be U-shaped. The unconnected end of the limiting pull rod 12 is fixedly installed with a hanging angle 121 outward. The hanging angle 121 cooperates with the hole 62 and the waist groove 71. The connected end of the limiting pull rod 12 is fixedly installed with an interference ring 10. The height of the interference ring 10 is flush with the connecting piece 13. It should be noted that the limiting pull rod 12 is elastic and can drive the hanging angle 121 out of the hole 62 with the pulling force.

[0037] In the present application, the hemostatic clamp is a disposable product. Therefore, when manufacturing the hemostatic clamp, the limiting pull rod 12 is first installed in the outer tube 5 so that the hanging angle 121 is in the hole 62. Then, the sleeve 7 is put on the convex ring 61, and the sleeve 7 is pushed to clamp the waist groove 71 on the hanging angle 121 to complete the fixation of the sleeve 7.

[0038] To summarize: after the hemostatic clamp is adjusted to the appropriate position, the operator manually pulls the slip ring 2 outward, causing the booster tube 3 and the cable 9 to move accordingly, and pulls the clip 8 into the jacket 7 until the clip 8 is closed and locked to complete the clamping operation;

[0039] The operator then continues to apply force to pull the connecting piece 13 outward, causing the arc piece 131 to deform and open outward, and separate from the nail rod 14, thereby preventing the connecting piece 13 from breaking and preventing debris from being left in the patient's body, reducing surgical risks and patient discomfort.

[0040] At the same time, after the connecting piece 13 is loosened, it enters the outer tube 5 along with the rope 9, and after contacting the interference ring 10, it pushes the interference ring 10 and the limiting pull rod 12 to move, pulling the hanging angle 121 out of the hole 62 and the waist groove 71, and finally making the jacket 7 and the clip 8 form independent individuals and detach from the whole, thereby completing use.

[0041] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
