The observation mirror has the characteristics of small lens, high reflectivity and anti-fog function. Generally, when performing surgery on cerebellopontine angle tumors, the tumor will grow into the internal auditory canal, which is difficult to observe directly under the microscope. This observation mirror is often needed to observe tumors that are difficult to observe.

[0003] For example, the utility model patent with announcement number CN216167351U discloses an adjustable oral observation mirror for children, including a handle, a slide groove, and a moving rod. The slide groove is located inside the handle, and the slide groove and the handle are an integrated structure. The moving groove is located above the right side of the handle, and the moving groove and the handle are an integrated structure; the fixed groove is located in the middle of the lower side of the handle, and the fixed groove and the handle are an integrated structure; the limit shaft is arranged at the lower left side of the fixed groove, and the limit shaft and the fixed groove are connected by welding; the moving rod is arranged inside the slide groove, and the moving rod is slidably connected to the slide groove; the upper end of the support rod is arranged on the lower side of the moving rod, and the support rod and the moving rod are hinged. Through structural improvements, it has the advantages of easy adjustment, safety protection and good shielding effect, thereby effectively solving the problems and shortcomings of the existing device.

[0004] The device controls the angle of the fixing frame by pulling a pull ring, so that the device can be easily adjusted. However, the limit axis of the device is located inside the limit groove, so that the angle adjustment range of the observation mirror is limited, and when the observation mirror does not need to be adjusted during normal use, it cannot remain stable. Therefore, a multi-angle observation mirror for neurosurgery is provided. Utility Model Content

The circular plate 9 is conveniently installed and fixed by the provided mounting rod 2 8.

[0023] refer to Figure 1 , Figure 2 An observation mirror 10 is fixedly installed on the front side of the circular plate 9, and an annular LED lighting lamp 19 is fixedly installed on the front side of the circular plate 9 at the side of the observation mirror 10. A switch button 21 is fixedly installed on the outer surface of the handle 1, and a battery pack 22 is fixedly installed inside the handle 1. The annular LED lighting lamp 19, the switch button 21 and the battery pack 22 are electrically connected. A protrusion 11 is fixedly installed on the rear side of the circular plate 9, and an adjustment mechanism 12 connected to the protrusion 11 is arranged inside the handle 1; through the observation mirror 10, it is convenient for surgical personnel to observe the internal auditory canal, and through the battery pack 22 and the switch button 21, it is convenient to control the start and stop of the annular LED lighting lamp 19, which is convenient for personnel to observe.

[0024] refer to Figure 2 , Figure 3 and Figure 4 The adjusting mechanism 12 includes a rotating shaft 13, a rotating block 14, a rectangular hole 15, a winding wheel 16, a connecting rope 17 and a threading hole 18. The interior of the handle 1 is rotatably connected to the rotating shaft 13 through a bearing. A rotating block 14 is fixedly installed on the outer surface of the rotating shaft 13 near the middle. A rectangular hole 15 is opened on the top surface of the handle 1; the rotating block 14 is provided to facilitate the rotation of the rotating shaft 13.

[0025] refer to Figure 2 , Figure 4 and Figure 5The outer surface of the rotating shaft 13 is located on the side of the rotating block 14, and a winding wheel 16 is fixedly installed thereon. A connecting rope 17 is wound around the inside of the winding wheel 16, and a lead hole 18 is opened on the front side of the handle 1. A circular sealing gasket 23 is fixedly installed inside the lead hole 18. One end of the connecting rope 17 passes through the inside of the lead hole 18 and extends to the outside of the handle 1. The end of the connecting rope 17 extending to the outside of the handle 1 is fixed to one side of the protrusion 11. The user rotates the rotating block 14, so that the rotating shaft 13 drives the winding wheel 16 to rotate, so that the connecting rope 17 is wound around the inside of the winding wheel 16. At this time, the circular plate 9 and the observation mirror 10 rotate under the drive of the connecting rope 17, so that the angle of the observation mirror 10 can be adjusted.

[0026] The implementation principle of the embodiment of a multi-angle observation mirror for neurosurgery of the present application is as follows: in a normal state, the circular plate 9 and the observation mirror 10 are kept at a fixed angle under the action of the torsion spring 6. When the user needs to use the observation mirror, the handle 1 can be picked up to allow the circular plate 9 and the observation mirror 10 to enter the internal auditory canal for observation. When the angle of the observation mirror 10 entering the internal auditory canal is limited and needs to be adjusted, the user first rotates the rotating block 14 with a finger part. When the rotating block 14 rotates, the left and right hands can cooperate to rotate. At this time, the rotating block 14 drives the rotating shaft 13 and the revolving wheel 16 to rotate. When the revolving wheel 16 rotates, it will cause The internal connecting rope 17 is wound up, and when the connecting rope 17 is wound up, the circular plate 9 and the observation mirror 10 are driven to rotate, so that the angle of the observation mirror 10 can be adjusted, and the user can observe the internal auditory canal from multiple angles through the observation mirror 10. The device has a simple structure and is easy to operate. The observation mirror 10 is kept at a fixed angle when not adjusted, so that the user can observe normally through the observation mirror 10. When adjustment is needed, the rotation of the wheel 16 will drive the connecting rope 17 to wind up, so that the angle of the observation mirror 10 changes. The angle of the observation mirror 10 can be adjusted to 180°, which improves the convenience of observation.
