Description

Technical Field

[0001] The utility model relates to the technical field of endoscope auxiliary devices, in particular to an endoscope tip cap. Background Art

[0002] The endoscope tip cap is an important medical device used to protect the tip of the endoscope from wear and tear. Since the endoscope needs to pass through various tissues of the human body, such as mucosa and muscles, its tip needs to be particularly delicate and avoid damage. It also assists in hemostasis treatment, foreign body removal, magnifying endoscopic examination, improving tangent position and endoscopic imaging observation of lesions in difficult areas. In addition, it creates a large enough space in the gap of the opened mucosal layer to facilitate cutting, coagulation and blunt separation operations, providing a wide and stable space for narrow foreign body retention areas, facilitating foreign body removal, while reducing the operator's psychological burden and shortening the operation time.

[0003] For example, the Chinese patent application "A Multifunctional Endoscope Tip Cap," published under publication number CN219183635U, features a transparent, thin-walled tubular body with circumferentially spaced scale lines at the lower end and a sloped structure at the upper end. This multifunctional endoscope tip cap not only features outwardly convex scale markings but is also reversible, allowing it to be used in various locations to meet diverse medical requirements.

[0004] Although the above-mentioned existing technology is provided with a drainage hole to achieve the discharge of accumulated liquid, the position of the drainage hole of most tip caps on the market is fixed, and the diameter and flow rate of the drainage hole are easily subject to design limitations, and a large amount of liquid cannot be discharged quickly, which may not be fully adapted to all surgical situations. Moreover, during the operation, the discharged liquid may contain tissue fragments, blood or other impurities, which may block the drainage hole, resulting in poor drainage or complete blockage. Therefore, it does not meet the existing needs. In this regard, we have proposed an endoscopic tip cap. Utility Model Content

[0005] The purpose of the utility model is to provide an endoscope tip cap to solve the problem in the above background technology that the drainage holes on the tip cap are poor in drainage and easily clogged during the convergence process.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an endoscope tip cap, comprising an assembly portion, a protective cap portion being provided at the upper end of the assembly portion, and the protective cap portion and the assembly portion being integrally injection molded, an outer wall of the assembly portion being provided with drainage grooves equidistantly distributed in a circular shape, the height of the drainage groove being set between six and twelve millimeters, and the spacing between adjacent drainage grooves being between one and two millimeters, a guide groove being provided at the bottom of the drainage groove, and the guide groove being an inclined structure.

[0007] Preferably, the axis of the assembly portion coincides with the axis of the protective cap portion, the inner diameter of the protective cap portion is smaller than the inner diameter of the assembly portion, and an assembly limiting step is formed at the connection position with the front end of the inner diameter.

[0008] Preferably, the assembly portion and the protective cap portion are both made of polycarbonate, and the tip cap body composed of the assembly portion and the protective cap portion is transparent.

[0009] Preferably, a connecting sleeve is provided at the upper end of the outer wall of the assembly part, the inner diameter of the connecting sleeve is smaller than the inner diameter of the assembly part, and the connecting sleeve is elastically fastened to the outside of the assembly part, and the outer wall of the connecting sleeve is provided with an annular expansion part.

[0010] Preferably, the connecting sleeve and the expansion portion are both made of silicone rubber.

[0011] Preferably, the angle between the horizontal plane where the guide groove is located and the horizontal plane where the drainage groove is located is less than ninety degrees.

[0012] Preferably, the angle between the horizontal plane where the guide groove is located and the horizontal plane where the drainage groove is located is sixty degrees.

[0013] Preferably, the guide groove passes through the limiting step.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The utility model adopts an annularly distributed drainage groove, which has a larger drainage area and can more effectively drain the liquid accumulated on the tip cap, significantly reducing the blurred vision and operation interruption caused by liquid accumulation, thereby improving the efficiency and safety of medical operations. Moreover, the design of the annular drainage groove is more in line with the principles of fluid dynamics, which can guide the liquid flow more smoothly and reduce the retention time of the liquid on the tip cap, which is not only conducive to keeping the tip cap clean and dry, but also reduces the risk of bacterial growth and cross infection caused by liquid retention.

[0016] 2. The utility model can enhance the structural stability of the tip cap. Since the drainage grooves are distributed in a circular and equidistant manner, the supporting force formed is more balanced. When the tip cap is subjected to external force, it can disperse the external force, thereby avoiding the risk of damage due to external force, extending its service life, and making it more durable and reliable.

[0017] 3. The present invention can reduce production costs. Although compared with traditional tip caps, it requires reasonable planning of production drawings and corresponding production-related molds, the tip cap consumes less material in the assembly part. In the long run, it can effectively reduce material consumption and thus improve economic benefits. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Working principle: When the endoscope enters the body and comes into contact with body fluids or a moist environment, moisture will accumulate on the outer wall of the tip cap. Due to the presence of the drainage groove 5, the accumulated moisture can flow rapidly along the guidance of the drainage groove 5, thereby avoiding the retention and accumulation of moisture on the outer wall of the tip cap. The design of the annular drainage groove 5 allows the moisture to be evenly discharged from all directions, improving the efficiency and effect of drainage. The control system of the endoscope can adjust the angle and position of the tip cap so that the drainage groove 5 is always in the best drainage position to ensure that the moisture can be discharged in time. Through the design of the annular drainage groove 5, the tip cap of the endoscope can effectively remove accumulated moisture and maintain the clarity of the field of vision. This is of great significance for doctors to make accurate diagnosis and treatment, and also improves the efficiency and safety of endoscope use.
