Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a peek device for anorectal surgery to prevent anal fissures in a rectal mirror. Background Art

[0002] A colonoscope can display the clearest image of the patient's lesions on the computer screen. The diameter of the mirror body is small and can be inserted from the anus into the rectum. The lens can perform inspections and treatments from multiple angles and directions, facilitating comparison, inquiry, and consultation of lesions. It plays a decisive role in the diagnosis and treatment of diseases such as proctitis, rectal polyps, gastrointestinal bleeding, hemorrhoids, and anal papilla hypertrophy.

[0003] After searching, a peep device for anorectal surgery to prevent anal fissure proctoscope with announcement number CN217525081U was found, comprising a proctoscope probing sleeve, wherein stretch ring bodies are respectively provided on both sides of one end surface of the proctoscope probing sleeve, and the stretch ring bodies are ring bodies made of semicircles. Gas injection holes are opened on the upper and lower end surfaces of one end surface of the proctoscope probing sleeve, and the gas injection holes are communicated with the gas outlet holes. When the proctoscope is inserted into the patient's anus, the four insertion plates designed at the front end of the proctoscope can be easily inserted into the patient's body. Because the insertion plates are trumpet-shaped as a whole, the insertion plates can be slowly inserted into the patient's anus. At the same time, when the proctoscope enters the middle of the four insertion plates, the proctoscope will stretch the four insertion plates, and the reset annular spring on the insertion plates will be stretched, and the reset annular spring can fix the proctoscope through the insertion plates.

[0004] Based on the above patent, the background technology mentioned in the patent discloses that the proctoscopes currently used in hospitals all have a hollow column as the main body. When the hollow column is inserted into the patient's anus, there is a risk that the front end of the hollow column will scratch the patient's rectum, making insertion difficult. In response to this technical problem, the present application proposes a proctoscope for preventing anal fissures in anorectal surgery. Summary of the Invention

[0022] 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.

[0023] Reference Figure 1-3 The utility model provides an embodiment: a peek device for anorectal proctoscope for preventing anal fissure, comprising a hollow tube 1, the inner wall of the right end of the hollow tube 1 is rotatably connected to two rotating blocks 2, the right ends of the rotating blocks 2 are fixedly connected to a protective plate 3, the right end of the protective plate 3 is provided with a round head 5, the left end of the round head 5 is fixedly connected to a clamping block 4 on both sides, the right end of the protective plate 3 is provided with a groove, the size of the clamping block 4 is matched with the groove, the front and back sides of the inner wall of the hollow tube 1 are fixedly connected to a connecting block 10, the connecting block 1 10 is fixedly connected to a fixing ring 9 at one end, and a connecting rod 7 is threadedly connected to the inner wall of the fixing ring 9. The right end of the connecting rod 7 is rotatably connected to the left end of the round head 5. The left end of the connecting rod 7 is fixedly connected to the turning handle 8. The right side of the outer wall of the connecting rod 7 is fixedly connected to a fixing block 12. The front and rear sides of the right end of the fixing block 12 are fixedly connected to a connecting block 2 13. The right end of the connecting block 2 13 is rotatably connected to a rotating rod 14. The outer wall of the rotating rod 14 is rotatably connected to a slider 15. The outward end of the slider 15 is slidably connected to the inner wall of the protective plate 3.

[0024] Specifically, when in use, the protective plate 3 and the round head 5 form a bullet-shaped head, so that when the hollow tube 1 is inserted into the patient's anus, the front end of the hollow tube 1 will not scratch the patient. At the same time, the streamlined head is conducive to the insertion of the hollow tube 1. After the hollow tube 1 is inserted, the turning handle 8 is rotated to move the connecting rod 7 in cooperation with the fixing ring 9, pushing the round head 5 to move so that the blocking block 4 releases the limit on the protective plate 3. At this time, the fixing block 12 will follow the movement of the connecting rod 7 to rotate the rotating rod 14, so that the slider 15 slides on the protective plate 3 and cooperates with the rotating block 2 to rotate and open the protective plate 3, completely exposing the end of the hollow tube 1 to facilitate the subsequent insertion of the rectal mirror.

[0025] Reference Figure 2 , the outer wall of the hollow cylinder 1 is fixedly connected with a plurality of air bags 11, the outer walls of the air bags 11 are provided with baffles 6, the outward ends of the air bags 11 are provided with inflation holes, and the outer walls of the baffles 6 are provided on the inner wall of the hollow cylinder 1;

[0026] Specifically, the baffle 6 is pulled out from the hollow tube 1 to expose the airbag 11, and then the airbag 11 is inflated through the inflation hole on the airbag 11 to make the airbag 11 swell, and the patient's anus is slowly expanded. The expansion of the airbag 11 can reduce the patient's pain and can be stopped at any time when the patient's tolerance reaches the limit to prevent anal fissures. The baffle 6 shields the airbag 11 to avoid the airbag 11 being displaced by the friction of the patient's anus during the insertion process, resulting in the airbag 11 not being completely located inside the anus and affecting the expansion effect.

[0027] Working principle: When in use, the protective plate 3 and the round head 5 form a bullet-shaped head, so that when the hollow tube 1 is inserted into the patient's anus, the front end of the hollow tube 1 will not scratch the patient. At the same time, the streamlined head is conducive to the insertion of the hollow tube 1. After the hollow tube 1 is inserted, the turning handle 8 is turned to move the connecting rod 7 in cooperation with the fixing ring 9, pushing the round head 5 to move so that the clamping block 4 releases the limit on the protective plate 3. At this time, the fixing block 12 will follow the movement of the connecting rod 7 to rotate the rotating rod 14, so that the slider 15 slides on the protective plate 3 and cooperates with the rotating block 2 to rotate and open the protective plate 3. The end of the hollow tube 1 is completely exposed to facilitate the subsequent insertion of the proctoscope. The baffle 6 is pulled out from the hollow tube 1 to expose the airbag 11, and then the airbag 11 is inflated through the inflation hole on the airbag 11 to make the airbag 11 bulge, and the patient's anus is slowly expanded. The expansion of the airbag 11 can reduce the patient's pain and can be stopped at any time when the patient's tolerance reaches the limit to prevent anal fissures. The baffle 6 shields the airbag 11 to prevent the airbag 11 from being displaced by the friction of the patient's anus during the insertion process, resulting in the airbag 11 not being completely located inside the anus and affecting the expansion effect.
