Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a disposable closure clip. Background Technology

[0002] Disposable closure clips are typically injection-molded from polymer materials (such as POM), placed on a base with a cover, packaged in a PET blister pack and dialysis paper, and then sterilized with ethylene oxide. They are classified as non-absorbable or absorbable depending on whether the material is biodegradable, and are for single use only. They are mainly used in surgical procedures to clamp blood vessels for hemostasis or to close tubular tissues, including small and medium-sized arteries and veins, bile ducts, etc., but are not suitable for large arteries and veins.

[0003] Existing closure clamps are prone to leakage after a period of time following closure due to structural issues. Utility Model Content

[0004] To address the aforementioned technical problems, a disposable closing clip is provided.

[0005] To achieve the above objectives, in a preferred embodiment of the present invention, the present invention is configured to include an upper clamping body and a lower clamping body, which are connected by a connecting section, and the inner walls of the upper clamping body and the lower clamping body are respectively provided with matching fitting structures.

[0006] In a preferred embodiment, the present invention may be further configured such that the fitting structure includes a pressure ridge, the pressure ridge is disposed on the inner wall of the lower clamping body and protrudes outward, and a pressure groove is disposed on the inner wall of the upper clamping body to cooperate with the pressure ridge.

[0007] In a preferred embodiment, the present invention may be further configured such that the upper clamp and the lower clamp are arc-shaped, and when not closed, they are circular with the connecting section.

[0008] In a preferred embodiment, the present invention may be further configured such that the pressing ridge and the pressing groove are opposite in shape and form an S-shape.

[0009] In a preferred embodiment, the present invention may be further configured such that the surface of the pressing edge and the bottom surface of the pressing groove are corrugated.

[0010] In a preferred embodiment, the present invention may be further configured such that the connecting segment is a flexible metal.

[0011] In a preferred embodiment, the present invention may be further configured such that a plurality of equidistant protrusions are provided on the outer wall surfaces of the upper and lower clamps.

[0012] Beneficial effects: This utility model provides a disposable closure clip with a ring structure, which can be quickly fitted into the blood vessel that needs to be closed. Applying pressure from both above and below simultaneously will close the clip into a strip shape, thus closing the blood vessel. The corrugated interlocking structure on the inner wall effectively reduces leakage. Attached Figure Description

[0013] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0014] Figure 1 This is a schematic diagram of the overall design of this utility model.

[0015] In the diagram, 1 is the upper clamping body; 2 is the protrusion; 3 is the pressing edge; 4 is the connecting section; and 5 is the lower clamping body. Detailed Implementation

[0016] 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.

[0017] like Figure 1 As shown, a disposable closure clip includes an upper clip body 1 and a lower clip body 5, which are connected by a connecting section 4. The inner walls of the upper clip body 1 and the lower clip body 5 are respectively provided with matching interlocking structures. When in use, pressure is applied to the upper clip body 1 and the lower clip body 5 at the same time. The connecting section 4 deforms due to the pressure, thereby bringing the opposing surfaces of the upper clip body 1 and the lower clip body 5 together to achieve the purpose of closure.

[0018] The fitting structure includes a pressure ridge 3, which is provided on the inner wall of the lower clamping body 5 and protrudes outward. A pressure groove is provided on the inner wall of the upper clamping body 1 to cooperate with the pressure ridge 3. The fitting of the pressure ridge 3 and the pressure groove further improves the closing effect.

[0019] The upper clamp 1 and the lower clamp 5 are arc-shaped. When not closed, they are circular with the connecting section 4, which makes them easy to store. They can be stacked on the column and removed when needed.

[0020] The pressure ridge 3 is opposite to the pressure groove in shape and is S-shaped, which increases the degree of closure of the tissue when closed.

[0021] The surface of the pressure ridge 3 and the bottom surface of the pressure groove are corrugated, which has stronger anti-leakage properties than a flat surface, greatly reducing the possibility of leakage.

[0022] The connecting segment 4 is made of flexible metal, which has good ductility and will not break easily.

[0023] The outer walls of the upper clamp 1 and the lower clamp 5 are provided with a number of equally spaced protrusions 2, which can increase friction when pressure is applied and prevent slippage.

[0024] It should be noted that in this article, relational terms such as first and second are used only to distinguish one entity from another, and do not necessarily require or imply any such actual relationship or order between these entities.

[0025] The above examples are merely illustrative of this utility model and do not constitute a limitation on the scope of protection of this utility model. All designs that are the same as or similar to this utility model are within the scope of protection of this utility model.
