[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] See also Figure 1-Figure 5 The utility model provides an auxiliary device for ear examination, including an auxiliary positioning frame 1 and an otoscope body 2, a connecting shell 3 is provided on one side of the auxiliary positioning frame 1, a connecting seat 4 is detachably installed on one side of the connecting shell 3 through a first connecting component, the first connecting component includes a first internal thread 12 opened on the inner wall of the connecting shell 3, a first external thread 13 matched with the first internal thread 12 is opened on the surface of the connecting seat 4, the connecting shell 3 is tightened and installed on the surface of the connecting seat 4 through the first internal thread 12 and the first external thread 13, the connecting seat 4 is detachably installed with the surface of the otoscope body 2 through a second connecting component, the second connecting component includes a second internal thread 14 opened in the inner cavity of the connecting seat 4, the surface of the otoscope body 2 is provided with a second external thread 15 matched with the second internal thread 14, the connecting seat 4 is tightened and installed on the surface of the otoscope body 2 through the second external thread 15 and the second internal thread 14.

[0024] In this embodiment, the auxiliary positioning frame 1 can be installed on the otoscope body 2 through the coordinated use of the first connecting component and the second connecting component. During installation, the user first needs to tighten the connecting seat 4 to one end of the otoscope body 2 through the second internal thread 14 and the second external thread 15, and then tighten the connecting shell 3 to the connecting seat 4 through the first internal thread 12 and the first external thread 13, thereby completing the installation of the auxiliary positioning frame 1 and the otoscope body 2.

[0025] Preferably, a handle 16 is installed at one end of the otoscope body 2, a data interface 17 is installed at the end of the handle 16 away from the otoscope body 2, the other end of the otoscope body 2 is fixedly connected to a mirror tube 18, and the end of the mirror tube 18 away from the otoscope body 2 is fixedly connected to a lens port 19. In this embodiment, the otoscope body 2 and an external display device can be connected together through the setting of the data interface 17, and the image inside the ear taken through the lens port 19 will be transmitted to the external display device through the otoscope body 2.

[0026] It is worth mentioning that a rubber pad 11 is fixedly installed on one side of the auxiliary positioning frame 1, and the surface of the rubber pad 11 is provided with anti-slip grooves. The provision of the rubber pad 11 can prevent the patient's face from directly contacting the auxiliary positioning frame 1. A connecting plate 5 is fixedly installed on the surface of the connecting shell 3, and an elastic limiting component for limiting the moving distance of the otoscope body 2 is installed at one end of the connecting plate 5. The connecting plate 5 is movably installed with the auxiliary positioning frame 1 through the elastic limiting component. The elastic limiting component includes a fixing tube 6 fixedly installed at the four corners of the inner cavity of the auxiliary positioning frame 1, and a compression spring 7 is fixedly installed in the inner cavity of the fixing tube 6. A connecting rod 8 is fixedly installed at one end of the compression spring 7. One end of the connecting rod 8 passes through the fixing tube 6 and extends to the outside of the fixing tube 6 and is fixedly connected to the surface of the connecting plate 5.

[0027] By setting the elastic limit assembly, when using the device, the user can fit the auxiliary positioning frame 1 around the patient's ear, and then adjust the otoscope body 2 to insert the lens port 19 and the mirror tube 18 into the patient's ear canal. During the inspection, the user can press the otoscope body 2 to continuously push the lens port 19 into the patient's ear canal, but its longest stroke is the position where the connecting plate 5 contacts one end of the fixing tube 6, which can limit the lens port 19 and prevent it from exceeding the cartilage part and causing discomfort and pain to the patient. By setting the compression spring 7, the compression spring 7 will be squeezed by the connecting rod 8 during the movement of the otoscope body 2 into the patient's ear canal. After the inspection is completed, the reaction force generated by the contraction of the compression spring 7 can push the otoscope body 2 to the outside, so that the lens port 19 is moved out of the ear canal.

[0028] Among them, a sliding component is also arranged between the surface of the connecting rod 8 and the inner wall of the fixed tube 6, and the sliding component includes sliding rods 9 fixedly installed on both sides of the inner cavity of the fixed tube 6. The surface of the connecting rod 8 is provided with a sliding groove 10 adapted to the sliding rod 9, and the inner wall of the sliding groove 10 is slidingly connected to the surface of the sliding rod 9. Through the setting of the sliding component, the stability of the connecting rod 8 in the fixed tube 6 can be improved to prevent it from being offset during the movement and causing its surface to be stuck with the inner wall of the fixed tube 6. During the movement of the connecting rod 8, the sliding groove 10 on its surface will be driven to slide on the surface of the sliding rod 9.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
