[0022] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0023] Referring to the drawings in the description Figures 1-5 The utility model provides a kind of head fixed body position frame, including soft pad 1, the soft pad 1 is processed with multiple air holes 8, the soft pad 1 is made of medical silica gel, the rear end of the soft pad 1 is processed with the mandibular groove 2 for adhering to patient's mandible, the both sides of the soft pad 1 are fixedly provided with rotating rod 3, two rotating rods 3 outer wall are all sleeved with mounting plate 4, two mounting plates 4 are all penetrated with adjustable screw 5, and the adjustable screw 5 one end penetrates mounting plate 4 and is in abutment with the outer wall of soft pad 1.

[0024] Two mounting plates 4 bottom are all fixedly provided with support assembly 6, and the support assembly 6 includes the support one 61 fixed in the bottom of mounting plate 4, two support ones 61 bottom are all detachably connected with support two 62, and the bottom of support two 62 is connected with fixed assembly 7.

[0025] In actual use, the medical staff first helps the ophthalmic patient lie on the ophthalmic operating bed, then helps the ophthalmic patient adjust the body position, then places the soft pad 1 at the chin of the ophthalmic patient, and then fixes the two fixing assemblies 7 on both sides of the ophthalmic operating bed, so that the soft pad 1 can support the head of the ophthalmic patient. Since the soft pad 1 is provided with the mandibular groove 2, the soft pad 1 can be fitted to the mandible of the ophthalmic patient, and the head of the ophthalmic patient is limited, so that the ophthalmic patient's head does not shake and affect the normal operation of the surgery. The medical staff does not need to hold the chin of the ophthalmic patient with his hand to fix it, which reduces the workload of the medical staff. Moreover, loosening the adjustable screw 5 can change the angle of the ophthalmic patient's head by rotating the soft pad 1. Moreover, the soft pad 1 is made of medical silica gel, which has no toxicity, low allergenicity, good elasticity and appropriate hardness. The soft pad 1 is provided with air holes 8, which can prevent skin pressure sores and will not damage the skin of the ophthalmic patient when supporting the head of the ophthalmic patient.

[0026] In this embodiment, as shown in Figure 1 and Figure 3 , the bracket one 61 comprises a support plate one 611 and an extension plate one 612 slidingly arranged inside the support plate one 611, and the bracket two 62 comprises a support plate two 621 and an extension plate two 622 slidingly arranged inside the support plate two 621. The support plate two 621 is detachably connected with the support plate one 611, and the support plate two 621 can also be connected with the extension plate one 612. The length of the bracket one 61 and the bracket two 62 is adjustable, so that the position of the soft pad 1 can be adjusted, and the flexibility of the soft pad 1 is improved.

[0027] The fixing assembly 7 comprises a vertical plate one 71 detachably mounted at the bottom end of the extension plate two 622. Two vertical plate twos 72 are slidingly arranged inside each vertical plate one 71. A metal snap ring 73 is fixedly arranged at the bottom end of each vertical plate two 72. The height of the metal snap ring 73 can be adjusted by pulling the vertical plate two 72 out of the vertical plate one 71, so as to meet the height fixing requirement of the soft pad 1.

[0028] Moreover, in order to facilitate the medical staff to quickly adjust the positions of the bracket one 61, the bracket two 62 and the metal snap ring 73, as shown in Figure 4 , two sleeves 9 are fixedly penetrated on the outer wall of each support plate one 611, each support plate two 621 and each vertical plate one 71. An insertion rod 10 is penetratingly arranged inside each sleeve 9. A plurality of insertion grooves 11 matched with the insertion rod 10 are processed on the outer wall of each extension plate one 612, each extension plate two 622 and each vertical plate two 72.
