[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Embodiment 1: A top plate 11 is fixed on the top of the protective cap body 1, and a rubber tightening ring 10 is fixed on the top of the top plate 11. The protective cap body 1 is connected to the interior of the top plate 11, and a mounting groove 6 is respectively opened on both sides of the interior of the top plate 11. A support slide rod 7 is fixed inside the mounting groove 6, and a slider assembly 5 is slidingly sleeved on the outer sides of both ends of the support slide rod 7. A connecting rod 12 is fixed on one side of the slider assembly 5, and one end of the connecting rod 12 extends out of the interior of the top plate 11. A second pressing plate 13 is fixed at one end of the two connecting rods 12, and a limit assembly 9 is fixed on both sides of the top plate 11. A protective groove 2 is opened at the bottom end of the interior of the protective cap body 1, and a rubber fixing belt 14 is fixed between the two slider assemblies 5. A reset spring 8 is sleeved on the outer side of the support slide rod 7.

[0021] Specifically, such as Figure 1 and Figure 2As shown, when the protective cap body 1 is installed at the front end of the digestive endoscope, the front end of the digestive endoscope can be inserted into the interior of the protective cap body 1 through the rubber tightening ring 10, so that the front end of the digestive endoscope is inserted into the protective groove 2. Since the rubber tightening ring 10 is extensible, it can fit with the outside of the digestive endoscope tube, thereby preventing foreign matter from entering the interior of the protective cap body 1 and contaminating the front end of the digestive endoscope during the protection process. Subsequently, by pressing the two second pressing plates 13, the two rubber fixing belts 14 are driven to move inside the top plate 11, thereby fixing the slider assembly 5 and the limit assembly 9, and at the same time compressing the return spring 8 sleeved on the outside of the support slide bar 7. The two rubber fixing belts 14 can further clamp the outside of the digestive endoscope tube to avoid the protective cap body 1 from falling off during use, and further improve the stability of the protective cap body 1 after installation and use. When the protective cap body 1 needs to be removed, the slider assembly 5 is controlled to disengage from one side of the limit assembly 9. At this time, the pressure on the compressed reset spring 8 disappears, and then the two second pressing plates 13 can be pushed apart by the rebound force of the reset spring 8, so that the two rubber fixing belts 14 cancel the clamping effect on the outside of the digestive endoscope tube, and then the protective cap body 1 is removed from the front end of the digestive endoscope. The disassembly and assembly process is very convenient and convenient for medical staff to use.

[0022] Example 2: The protective cap body 1 is fixed with spring telescopic rods 4 on both sides, and the output end of the spring telescopic rod 4 is fixed with a splint 3, and the two ends of the splint 3 are arc-shaped. The slider assembly 5 includes a slider body 501, and the slider body 501 is slidably sleeved on the outside of the support slide 7. A slide groove 503 is opened inside the slider body 501, and a first spring slide rod 502 is fixed inside the slide groove 503, and a limit block 504 is slidably sleeved on the outside of the first spring slide rod 502. One end of the limit block 504 extends out of the slide groove 503. Component 9 includes a limit seat 901, and one side of the limit seat 901 is connected to the inside of the mounting groove 6. Two limit holes 907 are opened on one side of the limit seat 901. A second spring slide rod 906 is fixed inside the limit seat 901, and a slide plate 903 is provided on the outer sliding sleeve of the second spring slide rod 906. Two support rods 905 are fixed on one side of the slide plate 903, and one end of the two support rods 905 extends out of the inside of the limit seat 901. A first pressing plate 904 is fixed to one end of the two support rods 905, and two push blocks 902 are fixed on one side of the slide plate 903.

[0023] Specifically, such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, when the two second pressing plates 13 are pressed, the two connecting rods 12 installed on one side of the second pressing plate 13 will drive the slider body 501 to slide along the installation direction of the supporting slide bar 7. When one end of the limit block 504 moves to the side of the limit hole 907, the extrusion force on one end of the limit block 504 disappears, and the one end of the limit block 504 extends into the interior of the limit seat 901, thereby limiting the second pressing plate 13 and clamping the outside of the digestive endoscope tube. By pressing the first pressing plate 904, the slide plate 903 can be driven to slide along the outside of the second spring slide bar 906. Since one side of the slide plate 903 Two pushing blocks 902 are fixed, and one end of the limiting block 504 extending into the limiting seat 901 can be pushed out of the limiting seat 901 through the pushing block 902. At this time, the limiting effect disappears, and the two second pressing plates 13 can be pushed out by the rebound force generated by the compressed reset spring 8, thereby canceling the clamping of the outside of the digestive endoscope tube. When the front end of the digestive endoscope is inserted into the protective cap body 1, the outside of the digestive endoscope tube will squeeze the two splints 3, thereby causing the two splints 3 to move relative to each other and compress the spring telescopic rod 4. The reaction force of the spring telescopic rod 4 can push the splint 3 to further clamp the digestive endoscope tube, thereby improving stability.

[0024] Working principle: When in use, the front end of the digestive endoscope is inserted into the interior of the protective cap body 1 through the rubber tightening ring 10, so that the front end of the digestive endoscope is inserted into the protective groove 2, and then the two second pressing plates 13 are pressed to drive the two rubber fixing belts 14 to move inside the top plate 11 so that the slider assembly 5 and the limit assembly 9 are fixed, and at the same time, the return spring 8 sleeved on the outside of the supporting slide bar 7 is compressed. The two ductile rubber fixing belts 14 can further clamp the outside of the digestive endoscope tube to avoid the protective cap body 1 from falling off during use. When the front end of the digestive endoscope is inserted into the interior of the protective cap body 1, the outside of the digestive endoscope tube will squeeze the two splints 3, so that the two splints 3 moves relative to each other and compresses the spring telescopic rod 4. The reaction force of the spring telescopic rod 4 can push the splint 3 to further clamp the digestive endoscope tube to improve stability. When removing, pressing the first pressing plate 904 can drive the slide plate 903 to slide along the outside of the second spring slide bar 906. Since two pushing blocks 902 are fixed on one side of the slide plate 903, the pushing block 902 can push one end of the limiting block 504 extending into the inside of the limiting seat 901 out of the inside of the limiting seat 901. At this time, the limiting effect disappears, and the two second pressing plates 13 can be pushed out by the rebound force generated by the compressed return spring 8, so as to cancel the clamping of the outside of the digestive endoscope tube and the protective cap body 1 can be removed from the front end of the digestive endoscope.

[0025] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
