[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. In this application, the traditional backrest component has been eliminated, which ensures the convenience of the patient in using the chair, facilitates the adjustment of the patient's body position, and avoids the backrest component from obstructing medical staff or medical equipment. After the patient straddles the saddle, his / her legs are placed on both sides of the horizontal end of the side frame, and the horizontal seat is placed above the legs. This can restrain the movement of the patient's legs and prevent the patient from standing up due to stress during the operation, thereby expanding the functionality of the special chair for ear endoscopy surgery.

[0015] 2. In this application, the horizontal seat drives the vertical bar to slide and engage with the inner surface of the vertical end of the side frame until the horizontal seat is raised to a suitable height. Then, the positioning rod is rotated to engage with the outer surface of the side frame. The vertical bar and the horizontal seat are fixed by the contact friction between the open end of the positioning rod and the vertical bar. This allows the vertical height of the horizontal seat to be easily adjusted according to the usage requirements, thereby improving the convenience of using the special chair for otoscopy surgery.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] An ear endoscopy surgery chair includes a caster base 1 and a saddle 2. Two sets of side frames 3 are fixedly connected to the bottom of the saddle 2. The vertical ends of the two sets of side frames 3 are distributed on the horizontal sides of the saddle 2. The top of each set of side frames 3 is integrated with a cross seat 4 and a lifting component for maintaining the height of the cross seat 4. The top of one set of side frames 3 is integrated with an instrument platform 5.

[0025] The traditional backrest component has been eliminated, ensuring the convenience of patient use and facilitating patient position adjustment. It also avoids obstruction of medical staff or equipment by the backrest component. After the patient straddles the saddle 2, their legs are placed on both sides of the horizontal end of the side frame 3, and the horizontal seat 4 is placed horizontally above the legs. This can restrain the patient's legs to a certain extent and prevent the patient from standing up due to stress during the operation, thereby expanding the functionality of the special chair for otoscopy.

[0026] Specifically, such as Figure 2 and Figure 4 As shown, the lifting assembly includes a vertical bar 7 and a locking part for locking the position of the vertical bar 7. The vertical bar 7 is fixedly connected to the horizontal seat 4 and inserted into the side frame 3. A protrusion 11 is fixedly connected to the outer side of the bottom of the vertical bar 7. The outer wall of the protrusion 11 is slidably connected to the inner wall of the side frame 3, so as to prevent the vertical bar 7 from completely separating from the side frame 3. The locking part includes a positioning rod 8 that is screwed into the inner wall of the side frame 3, and the open end of the positioning rod 8 abuts against the outer wall of the vertical bar 7. The horizontal seat 4 drives the vertical bar 7 to slide into the inner wall of the vertical end of the side frame 3 until the horizontal seat 4 is raised to a suitable height. Then, the positioning rod 8 is rotated to screw into the outer wall of the side frame 3. The vertical bar 7 is fixed to the horizontal seat 4 through the contact friction between the open end of the positioning rod 8 and the vertical bar 7, so that the vertical height of the horizontal seat 4 can be conveniently adjusted according to the usage requirements, thereby improving the convenience of using the special chair for otoscopy surgery.

[0027] Specifically, such as Figure 2 and Figure 3As shown, a damping telescopic rod 6 is rotatably connected to the top of the horizontal seat 4 via a damping pivot. The open end of the damping telescopic rod 6 is movably connected to the bottom of the instrument platform 5 via the damping pivot to ensure the flexibility of the instrument platform 5 position adjustment. The outer walls of the horizontal ends of the two sets of side frames 3 are fixedly connected with protrusions 9, and the two sets of protrusions 9 are fixedly connected to the bottom of the saddle 2 via two sets of locking rods 10, thereby ensuring the convenience of assembling and disassembling the two side frames 3.

[0028] Working principle: The traditional backrest assembly has been eliminated, ensuring the convenience of patient use and allowing for easy adjustment of the patient's position. It also avoids obstruction of medical staff or equipment by the backrest assembly. After the patient straddles the saddle seat 2, their legs are placed on either side of the horizontal end of the side frame 3. The transverse seat 4 is positioned horizontally above the legs, providing some restraint to the patient's legs and preventing them from standing up during surgery. This expands the functionality of the ear endoscopy chair. The transverse seat 4 drives the vertical bar 7 to slide against the inner wall of the vertical end of the side frame 3 until the transverse seat 4 is raised to a suitable height. Then, the positioning rod 8 is rotated to engage with the outer wall of the side frame 3. The contact friction between the open end of the positioning rod 8 and the vertical bar 7 secures the transverse seat 4, allowing for convenient adjustment of the vertical height of the transverse seat 4 according to usage needs, thus improving the ease of use of the ear endoscopy chair.
