[0036] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of this application.

[0037] This application provides an ophthalmic surgical fixation device.

[0038] Example 1, such as Figure 1-5 As shown.

[0039] An ophthalmic surgical fixation device, comprising a bed 1;

[0040] The bed frame 1 includes a bed board 11, support legs 12, and cross braces 13. Support legs 12 are located at each corner of the bottom surface of the bed board 11, and cross braces 13 are positioned between each pair of support legs 12. A headrest 2 is placed on the top surface of the bed frame 1. The surface of the headrest 2 has a head groove 21 and a neck groove 22. When the patient lies on the surface of the bed board 11, their head rests on the surface of the headrest 2, with their head in the head groove 21 and their neck in the neck groove 22, facilitating subsequent fixation of the patient's head using other structures.

[0041] An ophthalmic surgical fixation device includes a position adjustment assembly 3, which is installed on both sides of the bed 1.

[0042] The position adjustment assembly 3 includes a fixed frame 31, a track plate 32, ear plates 33, a rotating shaft 34, a foot pedal 35, a moving plate 36, a mounting plate 37, a linear motor platform 38, and a telescopic push rod 39. Two fixed frames 31 are vertically mounted on one side of the bed 1. The track plate 32 is installed between the two fixed frames 31. Ear plates 33 are respectively installed at the upper and lower ends of the track plate 32. The rotating shaft 34 rotatably connects the two ear plates 33. The bottom end of the rotating shaft 34 passes through the ear plates 33, extends to the lower end of the ear plates 33, and is used to install the foot pedal 35. The rotating shaft 34 passes through the moving plate 36. The movable plate 36 is screwed to the track plate 32 on one side. Rotation of the rotating shaft 34 causes the movable plate 36 to move up and down along the track plate 32. The other end of the movable plate 36 is fixedly connected to the bottom end of the mounting plate 37. The mounting plate 37 is slidably connected to one side of the bed 1. The up and down movement of the movable plate 36 causes the mounting plate 37 to move up and down. The linear motor platform 38 is mounted on the top of the mounting plate 37. The telescopic push rod 39 is mounted on the slider of the linear motor platform 38. The head fixing assembly 5 is mounted on the output end of the telescopic push rod 39. In use, medical personnel pedal the foot pedal 35 and then rotate the foot pedal 35, thereby rotating the rotating shaft 34. The rotation of the pivot 34 drives the movable plate 36 to move up and down, which in turn drives the mounting plate 37 to move up and down, thereby adjusting the height of the linear motor platform 38 on the surface of the mounting plate 37. The linear motor platform 38 can then drive the telescopic push rod 39 to move along the linear motor platform 38. The telescopic push rod 39 can extend and retract. Multiple foot pedal buttons are provided on the side of the support leg 12 to control the movement of the slider of the linear motor platform 38 and the extension and retraction of the telescopic push rod 39.

[0043] The foot pedal component 35 includes a turntable 351, a connecting shaft 352, and a foot pedal 353. The bottom end of the rotating shaft 34 is fixedly connected to the center of the turntable 351. The connecting shaft 352 is rotatably connected to one side of the bottom surface of the turntable 351. The foot pedal 353 is located at the bottom end of the connecting shaft 352. Stepping on the foot pedal 353 drives the turntable 351 to rotate, which in turn drives the rotating shaft 34 to rotate. This avoids patients having to operate the position adjustment component 3 with their hands, making operation more convenient and preventing medical staff from contaminating their hands with germs.

[0044] An ophthalmic surgical fixation device includes a head limiting component 4, which is provided on the top surface of the bed 1.

[0045] The head-limiting assembly 4 includes a top side plate 41, a top-limiting pillow 42, a bandage 43, and a support plate 44. The top side plate 41 is disposed on the upper side of the top surface of the bed 1, and the top-limiting pillow 42 is disposed on the inner side of the top side plate 41. A top groove is formed on the inner side of the top-limiting pillow 42. The two sides of the top-limiting pillow 42 are respectively fixedly connected to the two ends of the bandage 43, and the middle part of the bandage 43 is fixedly connected to the support plate 44. In use, the patient's head rests on the surface of the head pillow 2, and then the support plate 44 is placed under the patient's chin. The bandage 43 limits the top of the patient's head in the top groove of the top-limiting pillow 42. Then, the position of the head pillow 2 is adjusted so that the patient's head is located in the head groove 21 of the pillow and the neck is located in the neck groove 22. This not only limits the patient's head but also increases the patient's comfort.

[0046] An ophthalmic surgical fixation device includes a head fixation component 5, which is installed at the movable end of a position adjustment component 3. The patient's head is fixed by the head limiting component 4 and then by the head fixation component 5.

[0047] The head fixation assembly 5 includes a fixation frame 51, connecting rods 52, a head fixation plate 53, a forehead fixation plate 54, adjusting push rods 55, a top plate 56, and a rotating component 57. The fixation frame 51 has an L-shaped structure, and a pair of connecting rods 52 are installed at the right angle of the fixation frame 51. The other ends of the two connecting rods 52 are rotatably connected to the middle of the head fixation plate 53. The head fixation plate 53 has an arc-shaped structure, and its top end is fixedly connected to the forehead fixation plate 54. The adjusting push rods 55 are installed on the inner sides of both ends of the fixation frame 51. The top plate 56 is installed at the output end of the adjusting push rods 55. The rotating component 57 is installed at the bottom end of the head fixation plate 53 and is rotatably connected to the top plate 56. In use, the head fixation plate 53 is first moved to the sides of the patient's head by the position adjustment assembly 3. Then, the adjusting push rod 55 on the side of the head fixation plate 53 extends, thereby driving the side of the head fixation plate 53 to contact the patient's head via the top plate 56 and the rotating component 57. At this time, the adjusting push rod 55 stops working. Since the middle of the head fixation plate 53 is rotatably connected to the connecting rod 52, the side of the head fixation plate 53 rotates inward, and its top edge must tilt upward. At this time, the adjusting push rod 55 above the top edge of the head fixation plate 53 extends, pushing the top edge of the head fixation plate 53 and the forehead fixation plate 54 downward, so that they contact the patient's head, thereby fixing the patient's head. At this time, the side and top edges of the head fixation plate 53, as well as the forehead fixation plate 54, are all in contact with the patient's head, fixing the patient's head. The outer bottom end of the forehead fixation plate 54 is covered with a silicone pad. This increases the patient's comfort and avoids excessive pressure on the patient's forehead from the forehead fixation plate 54. The patient's head is securely fixed. The arc-shaped head fixation plate 53 can adapt to patients with various head shapes and can fix the patient's head at multiple points.

[0048] The head fixation plate 53 has a mounting groove 531 on its inner bottom end, and a distance sensor 532 is installed in the mounting groove 531. The distance sensor 532 is used to determine whether the side of the head fixation plate 53 is in contact with the patient's head.

[0049] The top of the fixation frame 51 is equipped with an eyelid opening component 6 to open the patient's eyelids.

[0050] The eyelid-opening assembly 6 includes a connecting tube 61, a spreading rod 62, an eyelid-opening structure 63, a rear end rod 64, a pushing shaft 65, and a movable push rod 66. The two spreading rods 62 are rotatably connected at their midpoints, with the top of their rotatable connection fixedly connected to one end of the connecting tube 61. The other end of the connecting tube 61 is fixedly connected to the fixing frame 51. The eyelid-opening structure 63 is located at the front end of the two spreading rods 62. The rear end of the two spreading rods 62 is rotatably connected to the rear end rod 64. The pushing shaft 65 is threaded through the rear end of the rear end rod 64. The pushing shaft 65 has a hand-tightening end at its rear end. The front end of the pushing shaft 65 is fixedly connected to the two movable push rods 66. The two movable push rods 66 are arranged in a V-shape and located inside the rear ends of the two spreading rods 62. The outer end of the movable push rod 66 is slidably connected to the inner end of the spreading rod 62. The connecting tube 61 is a gooseneck tube. In use, pull the connecting tube 61 to adjust the position of the eyelid opening structure 63, place the two eyelid opening structures 63 inside the patient's eyelid, and then rotate the hand-twisting end of the push shaft 65. The rear end of the opening rod 62 is opened by the moving push rod 66, and then the front end of the opening rod 62 drives the eyelid opening structure 63 to open the patient's eyelid and expose the eyeball.

[0051] When using this invention:

[0052] The patient lies on the bed surface, and the head is restrained by the head-limiting component. Then, the position adjustment component adjusts the position of the head-fixing component, which then secures the patient's head. Finally, the eyelid-opening component is used to open the patient's eyelids for the surgical procedure.
