DETAILED DESCRIPTION
[0017] 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 described embodiments 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 creative work are within the scope of protection of the present invention.
[0018] See also Figure 1-5 The present invention provides a technical solution: an inner auditory canal lighting device for deafness and rhinology, comprising a connecting tube 1, a rotating shaft 2, a rotating handle 3, a traction line 4, a battery 5, a lighting lamp holder 6, a first outer cover 7, a second outer cover 8, a slider 9, a compression spring 10, a bearing 11, a bottom frame 12 and a lighting lamp 13, wherein the connecting tube 1 is provided with the rotating shaft 2 inside, the rotating shaft 2 is fixedly provided with the rotating handle 3 at the top, the traction line 4 is wound around the middle upper part of the rotating handle 3, the lighting lamp holder 6 is provided and connected below the battery 5, the lighting lamp 13 is provided below the lighting lamp holder 6, the first outer cover 7 is fixed to the bottom of the lighting lamp holder 6, the inner lower part of the first outer cover 7 is connected to the second outer cover 8 through the compression spring 10, the upper part of the second outer cover 8 is connected with the traction line 4, the bottom of the second outer cover 8 is fixed with the slider 9, the bottom of the slider 9 is provided inside the bearing 11, and the bearing 11 is embedded inside the upper part of the bottom frame 12.
[0019] The bottom of the rotating shaft 2 is axially connected to the upper surface of the battery 5, and the rotating shaft 2 and the rotating handle 3 are an integrated structure, and the outer wall of the rotating handle 3 and the inner wall of the connecting tube 1 are fully connected, which makes it convenient for the rotating shaft 2 to rotate and also convenient to fix the position to a certain extent, and it will not rotate easily.
[0020] The first outer cover 7 and the second outer cover 8 are both open semicircular structures, and the second outer cover 8 forms a telescopic structure inside the first outer cover 7, and the bottom of the second outer cover 8 and the slider 9 are an integral structure, which is convenient for adjusting the length of the first outer cover 7 and the second outer cover 8 through the degree of telescoping of the first outer cover 7 and the second outer cover 8, and can well control the concentration of light.
[0021] The upper and lower top ends of the compression spring 10 are respectively welded to the inner top end of the first outer cover 7 and the outer top end of the second outer cover 8 , so as to facilitate the contraction of the second outer cover 8 under the action of the compression spring 10 .
[0022] The bearing 11 is embedded in the bottom frame 12 , and the bearing 11 is snap-fitted to the slider 9 at the bottom of the second outer cover 8 , so that the slider 9 can rotate inside the bearing 11 , thereby adjusting the position of the opening structure on the first outer cover 7 and the second outer cover 8 .
[0023] The bottom frame 12 includes an outer frame body 1201 and a sponge layer 1202, and the sponge layer 1202 is arranged inside the outer frame body 1201.

The sponge layer 1202 can be replaced conveniently and quickly, so as to achieve the effect of convenient continued use.
[0024] Working principle: When using the inner auditory canal lighting device for deafness and rhinology, first, it is necessary to extend and retract the first outer cover 7 and the second outer cover 8 of the entire device. During the extension and retraction process, the staff only needs to turn the rotating handle 3 so that the rotating handle 3 drives the rotating shaft 2 to rotate, so that the rotating shaft 2 drives the traction line 4 to be wound above the rotating shaft 2. During the winding process, the traction line 4 pulls the second outer cover 8, which drives the compression spring 10 to squeeze, so that a part of the second outer cover 8 enters the interior of the first outer cover 7, and the expansion size of the first outer cover 7 and the second outer cover 8 can be adjusted to achieve the effect of adjusting the range of light irradiation well. After the adjustment is completed, the sponge layer 1202 can be snapped into Inside the outer frame 1201, the entire bottom frame 12 is placed into the ear port position of the patient and snapped into the inside of the ear. After the snapping is completed, the battery 5 supplies power to the lighting lamp 13 to perform lighting work. During the lighting process, the doctor can continuously rotate the slider 9 at the bottom of the second outer cover 8 under the action of the bearing 11. During the rotation process, the staff can treat the patient's internal auditory canal in the open structure of the first outer cover 7 and the second outer cover 8 according to different positions, thereby completing the treatment work well. After the treatment is completed, the new sponge layer 1202 is re-engaged, and the treatment work for the next patient can be continued. The contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
