[0028] The inflation mechanism includes an inflation cylinder 10, a rotating disk 19 and a piston rod 22. The outlet end of the inflation cylinder 10 is connected with a delivery pipe 11. The connecting rod 8 is provided with an air bag 17 connected with the connecting sleeve 7. The connecting sleeve 7 is provided with a cavity connected with the air bag 17. The mounting plate 1 is slidably connected with a sliding seat 2. The sliding seat 2 is provided with an adjustment mechanism. One end of the piston rod 22 located in the inflation cylinder 10 is fixedly connected with a piston. When the piston rod 22 moves back and forth, the inflation cylinder 10 is connected with the connecting sleeve 7 through the delivery pipe 11 to inflate the air bag 17 on the connecting sleeve 7. Through grooves are provided in the center of the mounting frame 1 3, the mounting frame 2 4, the mounting frame 3 6 and the connecting sleeve 7, so as to facilitate processing of the expanded output through the through grooves.

[0029] The adjusting mechanism includes a mounting frame 24 fixed on the sliding seat 2, and a toothed ring 25 is rotatably connected to the surface of the mounting frame 24. The cleaning rod 5 passes through the toothed ring 25 and is slidably connected to the toothed ring 25. When the toothed ring 25 rotates, the movable sleeve 18 rotates in the connecting sleeve 7, and the connecting rod 8 is placed into the ear hole. The airbag 17 expands to expand the location. When the toothed ring 25 rotates, preliminary cleaning can be performed on the corresponding location.

[0030] The mounting plate 1 is provided with a switching mechanism, which includes a connecting frame 12 fixed on the mounting plate 1, and a gear 14 meshing with a gear ring 25 is connected to the surface of the connecting frame 12 in a fixed-axis rotation manner. The cross-sectional width of the gear 14 is greater than the cross-sectional width of the gear ring 25, so that when the mounting frame 12 moves, the gear ring 25 is always meshed with the gear 14, and when the gear 14 rotates, the gear ring 25 meshing with it can rotate. The gear 14 is penetrated and rotatably connected with a rotating rod 13, and a friction disk 15 is fixedly connected to the outer contour of the rotating rod 13 and the surface of the gear 14, and a friction disk is fixedly connected to the end of the rotating rod 13 away from the gear 14 A rotating disk 19 is provided on one side of the inflator 10, and a friction disk 24 that rotates synchronously with the rotating disk 19 is provided on the end of the rotating rod 13 to push the rotating rod 13 to move axially. When the friction disk 15 on the rotating rod 13 is close to and meshed with the friction disk 15 on the gear 14, the friction disk 24 on the rotating rod 13 is separated from the friction disk 24 on the rotating disk 19. When the rotating rod 13 is rotated, the corresponding gear 14 can be rotated. Conversely, when the friction disk 24 on the rotating rod 13 is close to and meshed with the friction disk 24 on the rotating disk 19, when the rotating rod 13 is rotated, the rotating disk 19 can be rotated.

[0031] A second fixing frame 28 is fixedly connected to the upper surface of the mounting plate 1; a connecting shaft that penetrates the second fixing frame 28 and is rotatably connected thereto is fixedly connected to the surface of the rotating disk 19; a second friction disk 24 corresponding to the rotating rod 13 is fixedly connected to the connecting shaft of the rotating disk 19; a movable rod 21 is movably connected to the surface of the rotating disk 19 via a rotating shaft; an end of the movable rod 21 away from the rotating disk 19 is movably connected to a piston rod 22 via a rotating shaft; and continuous rotation of the rotating disk 19 can enable the movable rod 21 movably connected to the rotating disk 19 to push the piston rod 22, thereby causing the piston rod 22 to reciprocate in the inflator 10 to inflate the airbag 17 on the connecting rod 8.

[0032] A fixing frame 20 is fixedly connected to the mounting plate 1, and an air cylinder 10 passes through the fixing frame 20 and is fixedly connected to the fixing frame 20. A one-way valve 1 is arranged at the connection point between the delivery pipe 11 and the connecting sleeve 7, and a pressure relief valve 29 corresponding to the one-way valve 1 is arranged on the outer wall of the connecting sleeve 7. When the piston rod 22 reciprocates, the one-way valve 1 and the pressure relief valve 29 cooperate to continuously inflate the connecting sleeve 7, so that the airbag 17 expands to expand the location, and when the pressure relief valve 29 is pressed, the airbag 17 can be automatically depressurized to cancel the expansion.

[0033] Example 2: Please refer to Figure 1 , Figure 6As shown, an otolaryngology treatment auxiliary expansion mechanism of the present embodiment, the surface of the sliding seat 2 away from the mounting frame 3 6 is fixedly connected with the mounting frame 1 3, and the end of the cleaning rod 5 close to the mounting frame 1 3 is fixedly connected with a blocking column 26, and the end of the blocking column 26 is smoothly set, and a spring 27 is sleeved on the outer contour of the cleaning rod 5, one end of the spring 27 is against the surface of the gear ring 25, and the other end of the spring 27 is against the blocking column 26, and the surface of the mounting frame 3 is fixedly connected with a convex block corresponding to the blocking column 26. When the gear ring 25 rotates on the mounting frame 2 4, the cleaning rod 5 passing through the friction disk 24 can rotate with the rotation of the gear ring 25, and the blocking column 26 fixedly connected to the cleaning rod 5 moves along the surface of the mounting frame 3 under the action of the spring 27. When the blocking column 26 contacts the convex block on the mounting frame 3, the cleaning rod 5 can be pushed to move axially, so that the end of the cleaning rod 5 away from the blocking column 26 moves, thereby automatically cleaning the expansion part to prevent the accumulation of debris in the expansion part from affecting subsequent treatment.

[0034] A sliding groove 16 is provided on the upper surface of the mounting plate 1, and the sliding seat 2 is located in the sliding groove 16 and is horizontally slidably connected thereto. When the sliding seat 2 moves on the mounting plate 1, the cleaning rod 5 can be moved away from the expansion portion, so that debris at the expansion portion can be removed.

[0035] The sliding groove 16 is penetrated by a screw rod 23 which is rotatably connected to the sliding seat 2. The screw rod 23 penetrates the sliding seat 2 and is screwed thereto. A handle is fixedly connected to the end of the screw rod 23. By rotating the handle fixedly connected to the screw rod 23, the fixed frame 20 can be accurately moved in the sliding groove 16, thereby realizing the movement of the cleaning rod 5 to the expansion position.

[0036] Combining Example 1 and Example 2, it can be known that the airbag 17 can be quickly and effectively inflated through the inflation mechanism, thereby achieving rapid expansion of the ear hole and other parts, reducing the trauma caused by the expansion process, providing a larger operating space, and facilitating subsequent diagnosis and treatment operations. Driven by the toothed ring 25, the ear hole and other parts can be preliminarily cleaned while expanding, which improves the diagnosis and treatment efficiency and reduces the patient's pain and discomfort. The movement and state of the expansion mechanism can be conveniently controlled through the design of the adjustment mechanism and the switching mechanism. The cooperation of the mounting frame 24 on the sliding seat 2 and the toothed ring 25 can easily adjust the position and angle of the brush 9, and can easily switch to the inflation mode or the adjustment mode when needed, without the need to replace tools or perform complicated operations. It has the advantages of versatility and stability, and can provide great convenience and help for the otolaryngology treatment process.

[0037] like Figure 1-Figure 5 As shown, the working process and principle of the present invention are as follows:

[0038] Step 1: Place the connecting rod 8 at the expansion position, switch it with the switching mechanism, push the friction disc 24 on the rotating rod 13 to move toward the rotating disc 19, and make the friction disc 24 coaxially fixedly connected with the rotating disc 19 close to mesh, switch it with the switching mechanism, rotate the rotating rod 13, so that the rotating disc 19 can be rotated, and the movable rod 21 movably connected with the rotating disc 19 can push the piston rod 22, so that the piston rod 22 reciprocates in the inflation cylinder 10, inflate the airbag 17 on the connecting rod 8, and expand the position where the airbag 17 is located;

[0039] Step 2, switch through the switching mechanism, push the friction disk 15 on the rotating rod 13 and the friction disk 15 on the gear 14 to engage, rotate the rotating rod 13, at this time the gear 14 rotates, the gear ring 25 meshing with the gear 14 rotates, the cleaning rod 5 passing through the friction disk 24 rotates with the rotation of the gear ring 25, and the blocking column 26 fixedly connected to the cleaning rod 5 moves along the surface of the mounting frame 3 under the action of the spring 27. When the blocking column 26 contacts the protrusion on the mounting frame 3, it can push the cleaning rod 5 to move axially, so that the cleaning rod 5 moves away from the end of the blocking column 26, thereby realizing automatic cleaning of the expansion part to prevent the accumulation of debris in the expansion part from affecting subsequent processing.
