[0028] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model. In the following, the terms "first" and "second" are only used for description purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features with "first" and "second" can explicitly or implicitly include one or more features. In the description of the embodiments of the present disclosure, unless otherwise specified, the meaning of "multiple" is two or more.

[0029] Referring to Figs. 1 to 3 The utility model provides an anti-adhesion endoscope tip head, including insertion part 10, lens cover 20, lens assembly 30 and LED light source 40, the lens cover 20 is sealed on one end of insertion part 10, the end face of the outer end of lens cover 20 is connected with the outer peripheral side by round smooth curved surface 21, lens assembly 30 is installed in insertion part 10, the outer end of lens assembly 30 passes out lens cover 20, and the outer end of lens assembly 30 protrudes the outer end face of lens cover 20, and LED light source 40 is installed in insertion part 10 and the working end is stretched out lens cover 20.

[0030] Wherein, in the application, the insertion part 10 is a cylindrical structure design, the inside forms a mounting space. The lens assembly 30 and LED light source 40 are both installed inside the insertion part 10. The lens assembly 30 is the necessary structure of the endoscope, and is also the prior art, and the application does not improve it, so the specific structure is not described here. In addition, the sealing between the lens sleeve 20 and the lens assembly 30 can be sealed by a sealing ring or epoxy resin to ensure normal connection of the two.

[0031] The anti-adhesion endoscope tip adopts a smooth arc surface 21 designed on the end face of the lens sleeve 20, which can facilitate the sliding of mucus relative to the lens sleeve 20, reduce the risk of mucus adhesion on the outer periphery of the lens assembly 30, and the conical design facilitates the lens to extend into the human natural cavity, reduces the stimulation of the end face edge of the lens sleeve 20 to the human natural cavity, and improves the comfort. The outer end of the lens assembly 30 protrudes from the outer end face of the lens sleeve 20, which can avoid the accumulation of mucus on the lens assembly 30, and to some extent, facilitate the mucus to automatically slide to the lens sleeve 20 when the entire endoscope moves in the human natural cavity. At the same time, the end faces of the lens sleeve 20 and the lens assembly 30 are not flat, which can achieve the anti-adhesion effect to some extent.

[0032] Referring to Figs. 1 to 3 In the application, in order to facilitate the installation of the lens assembly 30, the lens sleeve 20 is provided with a mounting hole 22, and the outer end of the lens assembly 30 is arranged in the mounting hole 22. The mounting hole 22 cooperates with the lens assembly 30 to fix the lens assembly 30 on the lens sleeve 20. In order to seal the connection between the lens assembly 30 and the mounting hole 22 and prevent mucus in the human natural cavity from entering the insertion part 10, in an improved embodiment of the application, the side wall of the outer end of the lens assembly 30 is connected to the inner wall of the mounting hole 22 by epoxy resin. The epoxy resin also forms a smooth transition chamfer on the outer end face of the mounting hole 22, which can prevent mucus from adhering to the side of the lens assembly 30 and the end face of the lens sleeve 20.

[0033] In addition, in the above improved embodiment, in order to facilitate the installation of the LED light source 40, at least one light source hole 23 is formed in the smooth arc surface 21, and the LED light source 40 is installed in the light source hole 23. In addition, in the above embodiment, the light source hole 23 is provided with two, which are symmetrically arranged on both sides of the mounting hole 22.

[0034] In some possible implementations, the lens assembly 30 is provided with an infrared light shielding glass 31 at the outer end thereof, and the outer peripheral side of the infrared light shielding glass 31 is sleeved with a light shielding ring 32 which is in abutment with the inner wall of the mounting hole 22. The main function of the infrared light shielding glass 31 is to prevent the internal structure of the lens assembly 30 from being directly contacted with the mucus in the natural cavity of the human body. The light shielding ring 32 is designed as the direct mounting contact member between the outer periphery of the infrared light shielding glass 31 and the inner part of the mounting hole 22, and can also prevent stray light on the peripheral side of the infrared light shielding glass 31 from entering the lens assembly 30, thereby ensuring the normal imaging of the lens assembly 30.

[0035] Referring to Fig. 3 In the improved embodiment described above, in order to reduce the adhesion of mucus on the connection between the end face of the outer end of the lens sleeve 20 and the peripheral side of the infrared light shielding glass 31, the end face of the outer end of the light shielding ring 32 protrudes from the end face of the outer end of the lens sleeve 20, and the end face of the outer end of the light shielding ring 32 does not protrude from the end face of the outer end of the infrared light shielding glass 31. Such a design can form a continuous stepped structure between the end face of the outer end of the infrared light shielding glass 31, the light shielding ring 32 and the lens sleeve 20, and since the height difference between the three is very small, the end face of the outer end of the infrared light shielding glass 31, the light shielding ring 32 and the lens sleeve 20 can be regarded as a continuous arc-shaped transition surface. Such a design can prevent mucus from remaining between the peripheral side of the infrared light shielding glass 31 and the end face of the outer end of the lens sleeve 20.

[0036] In the improved embodiment described above, the outer end of the lens assembly 30 protrudes from the outer end face of the lens sleeve 20 by 0.03-0.07 mm, and preferably by 0.05 mm in the present application. Therefore, the height difference between the two is very small, and thus the two can be regarded as a plane. However, since the two are not actually a plane, the design can reduce the adhesion of mucus on the plane to some extent.

[0037] In some possible implementations, in order to enhance the anti-adhesion capability, the outer side of the lens sleeve 20 is coated with a nano coating. The nano coating is a conventional nano anti-adhesion coating, which is similar to the coating material used in a common non-stick pot. Of course, other anti-adhesion coatings can also be used in some embodiments.

[0038] Referring to Fig. 3 In the embodiment described above, in order to improve the anti-adhesion capability, the radius of curvature of the smooth arc surface 21 gradually increases along the axis of the lens sleeve 20 towards the end of the insertion part 10. Such a design makes the entire lens sleeve 20 have a structure of a tapered cylinder with an acute angle. In addition, in an improved embodiment, the lens sleeve 20 is made of stainless steel, which is convenient for sterilization and cleaning in later stage.

[0039] The above merely describes a specific implementation of the present application, but the protection scope of the present application is not limited thereto, any change or replacement within the technical scope disclosed by the present application should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
