[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1-3 The utility model provides an embodiment: an endoscope lens protection structure, including an endoscope 8, a connecting tube 1 is fixedly connected to the bottom of the endoscope 8, a disassembly component 71 is arranged inside the connecting tube 1, a lens 4 is slidably connected to the outer periphery of the endoscope 8, a protective cover 2 is slidably connected to the outer periphery of the lens 4, a sealing gasket 3 is fixedly connected to the bottom of the protective cover 2, a limiting ring 5 is fixedly connected to the upper part of the connecting tube 1, a limiting groove 9 is arranged inside the sealing gasket 3, the diameter of the sealing gasket 3 matches the diameter of the connecting tube 1, and the inner diameter of the lens 4 matches the diameter of the endoscope 8.

[0024] Specifically, the endoscope 8 is used for the inspection and treatment of the digestive tract, respiratory tract, urogenital system, cardiovascular system and other parts, which need to go deep into the human body. The connecting tube 1 is used to extend the endoscope 8 so that it is convenient to go deep into the human body for observation. The lens 4 is used to enlarge the photographic magnification of the endoscope 8 to facilitate detailed inspection of the internal organs. The protective cover 2 is used to protect the lens 4 to prevent body fluids from directly corroding the lens and affecting the imaging of the endoscope 8. It can also play a buffering role to prevent the endoscope 8 from falling to the ground and breaking the lens 4. The edge of the protective cover 2 is smooth and has no irregularities, which can reduce discomfort to the human body. The sealing gasket 3 is used to prevent body fluids from flowing into the protective cover 2 from the gap and corroding the internal components. The limiting ring 5 and the limiting groove 9 can cooperate to fix the protective cover 2 to prevent the protective cover 2 from falling off. The elasticity of the sealing gasket 3 and the protective cover 2 makes it easy to remove them from the limiting ring 5. The cooperation of the limiting ring 5 and the limiting groove 9 can also block the body fluids and play a waterproof role.

[0025] Reference Figure 1-3The disassembly component 71 includes a connecting plate 711, a card block 712 is fixedly connected to the upper part of the connecting plate 711, a button 713 is fixedly connected to the lower part of the connecting plate 711, a compression spring 714 is fixedly connected to the middle part of the connecting plate 711, two evenly distributed card slots 715 are opened at the lower part of the lens 4, and a slide groove 716 is opened at the lower part of the protective cover 2. The connecting plate 711 is slidably connected to the connection between the connecting tube 1 and the endoscope 8, the card block 712 is slidably connected to the lower part of the endoscope 8, and the button 713 is slidably connected to the upper part of the connecting tube 1. The height of the slide groove 716 matches the height of the button 713, the height of the card block 712 matches the height of the card slot 715, the card block 712 is slidably connected inside the card slot 715, and the button 713 is slidably connected inside the slide groove 716.

[0026] Specifically, the disassembly component 71 constitutes the disassembly structure 7, the connecting plate 711 is used to link the button 713 and the block 712, the block 712 is used to clamp the lens 4 on the periphery of the endoscope 8, the button 713 is used to drive the connecting plate 711 to make the block 712 move out of the slot 715, the button 713 is stuck in the slide groove 716 to reduce the discomfort caused by the irregularity to the human body, and the protective cover 2 can also be fixed, and the compression spring 714 is used to pop out the connecting plate 711 to make the block 712 stuck in the slot 715.

[0027] Reference Figure 1-3 The upper part of the protective cover 2 is rotatably connected with a lens 6, the surface of the lens 6 is coated with a polytetrafluoroethylene coating, the material of the sealing gasket 3 is polyethylene, and the material of the protective cover 2 is silicone.

[0028] Specifically, the lens 6 is used to facilitate the endoscope 8 to perform required photographic observations. The polytetrafluoroethylene coating is a material with excellent anti-stick properties, which can prevent liquid or tissue from remaining on the surface of the lens 4, reducing the possibility of blurring and damage to the lens 4. Polyethylene is a common medical-grade polymer material. Polyethylene has certain elasticity and chemical resistance, and is suitable for protecting the lens 4 and sealing the protective cover 2 to prevent liquid from flowing into the inside of the protective cover 2, corroding the lens 4 and affecting imaging. Silicone is a highly elastic and biocompatible material. Silicone has excellent waterproof properties and is relatively gentle on the patient's skin, which can reduce discomfort to the human body.

[0029] Working principle: when the lens 4 needs to be replaced, the button 713 is pressed to make the connecting plate 711 and the card block 712 separate from the card slot 715, and then the lens 4 is taken out for replacement. When installing the lens 4, it is only necessary to align the card slot 715 in the lens 4 with the position of the card block 712 on the surface of the endoscope 8 and then install it so that the card block 712 is stuck in the card slot 715 to complete the installation. When installing the protective cover 2, first expand the diameter of the sealing gasket 3 and then slide it to the outer periphery of the lens 4 to completely wrap the lens 4, let the limit ring 5 be stuck in the limit groove 9, and then let the button 713 be stuck in the slide groove 716 to complete the installation of the protective cover 2.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
