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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0018] See also Figure 1-4 The utility model provides a technical solution: a fundus angiography positioning auxiliary device, including a positioning bracket 1. Preferably, the positioning bracket 1 is provided with two groups. The positioning bracket 1 is a right-angle structure. When in use, one side of the positioning bracket 1 can be fixed on a table board or an external support frame. An adjusting plate 4 is slidably installed on the positioning bracket 1. The ends of the adjusting plate 4 are fixed with a guide frame 3. The guide frame 3 is slidably arranged on the outside of the positioning bracket 1. When the height of the adjusting plate 4 is adjusted, the guide frame 3 slides on the outside of the positioning bracket 1 to guide the movement of the adjusting plate 4. The support positioning height of the device can be adjusted by changing the height of the adjusting plate 4, which is convenient for use by patients with different body shapes.

[0019] A positioning component for positioning the adjustment plate 4 is provided on the outside of the positioning bracket 1. Insertion holes 2 are evenly opened on the side of the positioning bracket 1 from top to bottom. The positioning component includes a mounting seat 10 fixed on the side of the guide frame 3. A movable guide rod 11 is slidingly provided in the mounting seat 10, and the movable guide rod 11 is adapted to the insertion hole 2, and a pull ring 14 is fixed on the end of the movable guide rod 11 away from the positioning bracket 1. The set pull ring 14 is convenient for controlling the movable guide rod 11 to slide in the mounting seat 10. When the movable guide rod 11 corresponds to the insertion hole, the movable guide rod 11 can be slid into the insertion hole. The guide frame 3 is positioned on the outside of the positioning bracket 1 by the set movable guide rod 11, thereby realizing the positioning use after the height adjustment of the adjustment plate 4, and ensuring the stability of the device during use.

[0020] A sliding hole is provided on the side of the mounting seat 10, and the moving guide rod 11 is slidably installed in the sliding hole. A sliding groove is provided inside the mounting seat 10, and a limit plate 12 slidingly arranged in the sliding groove is fixed to the side of the moving guide rod 11. A positioning spring 13 is provided in the sliding groove and is sleeved on the outside of the moving guide rod 11, and the positioning spring 13 is located between the limit plate 12 and the pull ring 14. When the moving guide rod 11 is pulled outward by the pull ring 14, the limit plate 12 on the side of the moving guide rod 11 squeezes the positioning spring 13. When the moving guide rod 11 corresponds to the insertion hole, the positioning spring 13 pushes the limit plate 12 by its own elasticity to make the moving guide rod 11 move and insert into the corresponding hole, which is convenient for the use of the positioning assembly; and during the positioning process of the positioning assembly, the positioning spring 13 limits the limit plate 12 by its own elastic supporting force to prevent the moving guide rod 11 from slipping out of the insertion hole.

[0021] A support plate 5 is fixed on the upper side of the adjustment plate 4, and a mounting frame 6 is fixed on the top of the support plate 5. A movable plate 7 is slidably installed in the mounting frame 6, and a support tray 9 is installed on the upper side of the movable plate 7. When the device is in use, the patient's head is supported by the support tray 9, thereby reducing the shaking of the patient's head during fundus angiography. The front and rear positions of the support tray 9 can be adjusted by sliding the movable plate 7 in the mounting frame 6, which is convenient for adjusting the position of the support tray 9 according to the patient's usage needs and effectively positioning the patient's chin, thereby supporting the patient's head, ensuring the stability of the patient's head and eyes during angiography, and ensuring fundus angiography of the patient.

[0022] The movable plate 7 has a horizontal L-shaped structure, and a fixing rod 8 is fixed in the mounting frame 6. Preferably, two fixing rods 8 are provided to improve its structural strength while ensuring its stability during use. The movable plate 7 is slidably connected to the fixing rod 8. The fixing rod 8 plays a positioning role for the movable plate 7 to prevent the movable plate 7 from being forced to separate from the mounting frame 6. A positioning sleeve 71 is fixed on the side of the movable plate 7, and the positioning sleeve 71 is slidably mounted on the fixing rod 8. The positioning sleeve 71 is used to increase the contact area between the movable plate 7 and the fixing rod 8 to ensure the stability of the movable plate 7 during use.
