Description

Technical Field

[0001] This utility model relates to the field of closure clip technology, specifically to a biodegradable disposable closure clip. Background Technology

[0002] Disposable closure clips are medical devices used to clamp tissues. They can use their own mechanism to lock together. In the current technology, it is relatively difficult to remove the closure clips after they are locked together, which makes them less convenient to use.

[0003] For example, patent publication number CN221266224U describes a disposable tissue closure clip, including a polyoxymethylene (POM) V-shaped plate and a disassembly / removal mechanism. The POM V-shaped plate has a small window on its front surface, a first arched leg at its lower end, a protrusion at the left end of the first arched leg, a locking groove in the center of the protrusion's surface, and a second arched leg at its upper end, with a locking mechanism at the left end of the second arched leg. The locking mechanism engages with the locking groove. The disassembly / removal mechanism is located on the outer sides of the first and second arched legs. This disposable tissue closure clip allows for single use, ensuring cleanliness and hygiene, facilitating the application of force during removal, and enabling faster disassembly and removal, reducing the time required for removal and increasing work efficiency. However, the interlocking of the clips before removal is laborious, making its ease of use less than ideal. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a biodegradable disposable closure clip, which solves the problem that it is difficult to remove the closure clips after they have interlocked, making them less convenient to use.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a biodegradable disposable closure clip, including a V-shaped plate, with a first clamping leg and a second clamping leg fixedly connected to both ends of the V-shaped plate, the first clamping leg having a quick-release engagement mechanism at its end, and the second clamping leg having a clamping mechanism inside;

[0006] The quick-release engagement mechanism includes an engagement head with an engagement hook at the bottom. Both sides of the engagement head have slots, and each slot has a pressing head movably connected inside. Each pressing head has a limit block fixedly connected to it, and each pressing head has a cutting blade fixedly connected to its end. The end of the engagement head has a connecting block fixedly connected to it, and both sides of the connecting block have cutting grooves.

[0007] Preferably, the end of the second clamping leg is provided with a biting groove, which matches the biting head and the biting hook, so that the biting head and the biting hook can be engaged and fixed in the biting groove.

[0008] Preferably, the end of the extrusion head passes through the slot and extends to the outside of the slot, and the limiting block is disposed inside the slot, which can facilitate pressing the extrusion head and prevent the extrusion head from separating from the engagement head.

[0009] Preferably, one end of the connecting block is fixedly connected to the end of the first clamping leg, and the other end of the connecting block is fixedly connected to the inner wall of the biting head, so that the biting head can be fixed on the first clamping leg.

[0010] Preferably, the cross-sectional shape of the cutting groove is set as a triangle, and the two cutting grooves are symmetrically arranged on both sides of the connecting block, so that the cutting blade can cut the connecting block more easily along the cutting groove.

[0011] Preferably, the clamping mechanism includes a movable plate disposed inside the second clamping leg, and the movable plate is slidably connected to the inner wall of the second clamping leg via a slider groove. A plurality of clamping blocks are fixedly connected to the top surface of the movable plate, and a lifting airbag is provided at the bottom of the movable plate. One end of the lifting airbag is connected to an air tube, and the end of the air tube is fixedly connected to a pressure-bearing airbag. The pressure-bearing airbag is fixedly installed at the end of the second clamping leg, which can improve the clamping effect.

[0012] This invention provides a biodegradable disposable closure clip. Compared with the prior art, it has the following advantages:

[0013] 1. This biodegradable disposable closure clamp allows medical personnel to press the squeezing head, which moves to drive the cutting blade to cut the connecting block, separating the biting head from the first clamp leg. This allows the first clamp leg to be quickly separated from the second clamp leg, enabling labor-saving and rapid disassembly, thus effectively improving the convenience of use.

[0014] 2. This biodegradable disposable closed clamp uses a pressure-bearing airbag to deliver gas into the lifting airbag. The lifting airbag inflates and lifts the movable plate upward, allowing the movable plate to fit more closely to the tissue and improving the clamping effect. Attached Figure Description

[0020] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 This utility model provides a technical solution: a biodegradable disposable closure clip, which is made entirely of biodegradable plastic material and can be completely degraded by environmental microorganisms after disposal, making it more environmentally friendly. It includes a V-shaped plate 1, with a first clamping leg 3 and a second clamping leg 5 fixedly connected to both ends of the V-shaped plate 1. The end of the first clamping leg 3 is provided with a quick-release engagement mechanism 2, and the inside of the second clamping leg 5 is provided with a clamping mechanism 4. The first clamping leg 3 and the second clamping leg 5 can be engaged and fixed by the quick-release engagement mechanism 2, and can be quickly and effortlessly removed, thereby effectively improving the convenience of use.

[0022] The quick-release engagement mechanism 2 includes an engagement head 201, with an engagement hook 202 at its bottom end and an engagement groove at the end of the second clamping leg 5. The engagement groove matches the engagement head 201 and the engagement hook 202, allowing the engagement head 201 and the engagement hook 202 to engage and be fixed in the engagement groove. Both sides of the engagement head 201 have slots 208, and each slot 208 has a movably connected pressing head 203. Each pressing head 203 has a fixedly connected limit block 204. The end of the pressing head 203 passes through the slot 208 and extends outside the slot 208. The limit block 204 is located inside the slot 208, allowing for easy pressing of the pressing head 203 and preventing the pressing head 203 from engaging with the slot. The biting head 201 separates, and a cutting blade 205 is fixedly connected to the ends of both extrusion heads 203. A connecting block 206 is fixedly connected to the end of the biting head 201. One end of the connecting block 206 is fixedly connected to the end of the first clamping leg 3, and the other end of the connecting block 206 is fixedly connected to the inner wall of the biting head 201, so that the biting head 201 can be fixed on the first clamping leg 3. Cutting grooves 207 are provided on both sides of the connecting block 206. The cross-sectional shape of the cutting grooves 207 is set as triangular. The two cutting grooves 207 are symmetrically arranged on both sides of the connecting block 206, so that the cutting blade 205 can cut the connecting block 206 more easily along the cutting grooves 207, thereby allowing the biting head 201 to separate from the first clamping leg 3 and release the lock.

[0023] Please see Figure 1 and Figure 4 The clamping mechanism 4 includes a movable plate 401, which is disposed inside the second clamping leg 5. The movable plate 401 is slidably connected to the inner wall of the second clamping leg 5 through a slider groove. Multiple clamping blocks 402 are fixedly connected to the top surface of the movable plate 401. A lifting airbag 403 is provided at the bottom of the movable plate 401. One end of the lifting airbag 403 is connected to an air tube 405. The end of the air tube 405 is fixedly connected to a pressure-bearing airbag 404. The pressure-bearing airbag 404 is fixedly installed at the end of the second clamping leg 5. After the clamping is locked, the pressure-bearing airbag 404 is pressurized and gas is sent into the lifting airbag 403. The lifting airbag 403 inflates and lifts the movable plate 401 upward, so that the movable plate 401 can fit more closely to the tissue and improve the clamping effect.

[0024] During operation, the first clamp leg 3 and the second clamp leg 5 are installed inside the clamping forceps. Medical staff use the clamping forceps to engage the first clamp leg 3 and the second clamp leg 5 together, so that the clamping head 201 bites into the clamping groove. When removal is required, medical staff press the squeezing head 203. The squeezing head 203 moves and drives the cutting blade 205 to move, so that the cutting blade 205 moves along the cutting groove 207 and cuts the connecting block 206, so that the clamping head 201 separates from the first clamp leg 3. This allows the first clamp leg 3 and the second clamp leg 5 to be separated quickly and effortlessly, thus effectively improving the convenience of use.

[0025] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
