[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] like Figures 1 to 7As shown, this utility model provides a head fixation device for ophthalmic care, including a support and fixation base 1. A fixing ring 2 is embedded in the top of the support and fixation base 1. A plurality of evenly distributed fixing airbags 3 are fixedly connected to the inner side of the fixing ring 2. A limiting component 4 is provided inside the support and fixation base 1. A fastening component 5 is provided inside the limiting component 4. The upper end of the fastening component 5 is fixedly connected to the bottom of the fixing ring 2. An adjusting component 6 is provided inside the fixing ring 2. The back of the adjusting component 6 is simultaneously interconnected with the plurality of fixing airbags 3. An exhaust plug 7 is connected to the back of the support and fixation base 1. The front end of the exhaust plug 7 extends into the interior of the adjusting component 6. Due to the setting of the fixing ring 2, the position of the head can be fixed by the fixing airbag 3 in cooperation with the adjusting component 6. At the same time, the angle of the head can be adjusted and fixed in advance by the fastening component 5 in cooperation with the limiting component 4, thereby effectively improving the stability of the patient's head after anesthesia and helping to improve the success of surgical treatment. Due to the setting of the exhaust plug 7, after use, the exhaust plug 7 can be opened and the piston plate 63 can be pushed by the adjusting rod 64 to make the adjusting rod 64 be stored in the adjusting cavity 61. Then, the exhaust plug 7 can be tightened to keep the neatness of the device exterior, thereby improving the convenience of storage.
[0025] like Figure 3 and Figure 4 As shown, the limiting component 4 includes a slide groove 41 opened inside the support fixing base 1. The front and rear ends of the slide groove 41 extend to the front and rear sides of the support fixing base 1, respectively. A limiting groove 42 is opened in the middle of the support fixing base 1, and the limiting groove 42 is connected to the top of the slide groove 41. Due to the setting of the slide groove 41, the movement of the positioning slider 51 can be well restricted. This ensures that the positioning slider 51 can rotate with the fixing ring 2, thereby adjusting the angle of its fixing head. At the same time, it ensures that the positioning slider 51 and the fixing ring 2 can be fixed as a whole by the positioning slide rod 52 and the fastening bolt 53.
[0026] like Figure 3 As shown, the fastening assembly 5 includes a positioning slider 51 that is slidably engaged inside the limiting groove 42. The top of the positioning slider 51 passes through the limiting groove 42 and extends to the outside of the support fixing seat 1 and is fixedly connected to the middle of the bottom of the fixing ring 2.
[0027] like Figures 2 to 4 As shown, a positioning slide rod 52 is fixedly sleeved inside the positioning slider 51. The two ends of the positioning slide rod 52 pass through the positioning slider 51 and the slide groove 41 and extend to the front and rear sides of the support fixing seat 1, and a fastening bolt 53 is threadedly sleeved on them. The positioning slide rod 52 is slidably connected to the inside of the slide groove 41, and the facing surfaces of the two fastening bolts 53 are tightly fitted to the front and rear sides of the support fixing seat 1.
[0028] like Figure 5 and Figure 6As shown, the adjustment assembly 6 includes an adjustment cavity 61 inside the fixing ring 2. The top of the fixing ring 2 has several connecting holes 62 that connect the adjustment cavity 61 and the rear ends of several fixing airbags 3 facing each other. The front of the fixing ring 2 has a through hole 65 that connects to the front of the adjustment cavity 61 and two adapter ports 66. The two adapter ports 66 connect to the left and right sides of the through hole 65. Due to the arrangement of several connecting holes 62, the adjustment cavity 61 can communicate with several fixing airbags 3 at the same time, thereby ensuring that the staff can press gas into the interior of several fixing airbags 3 through the adjustment rod 64 and the piston plate 63, so that the inflated fixing airbags 3 can be raised to the height of the patient's head.
[0029] like Figures 4 to 7 As shown, a piston plate 63 is slidably engaged inside the adjusting cavity 61. The piston plate 63 is sealed and connected inside the adjusting cavity 61. An adjusting rod 64 is connected to the front of the piston plate 63. The front end of the adjusting rod 64 passes through the adjusting cavity 61, the through hole 65 and the adapter port 66 and extends to the front of the fixing ring 2.
[0030] like Figure 7 As shown, the adjusting rod 64 includes an adjusting rod body 641 sleeved inside the through hole 65. The back of the adjusting rod body 641 is rotatably connected to the front of the piston plate 63. Several evenly distributed positioning blocks 642 are fixedly connected to the left and right sides of the outer surface of the adjusting rod body 641. The size of the outer surface of the positioning block 642 is adapted to the inner diameter of the fitting port 66. The distance between two adjacent positioning blocks 642 is greater than the distance between the front end of the inner cavity of the adjusting cavity 61 and the front of the fixing ring 2. Due to the setting of the positioning blocks 642, with the cooperation of the fitting port 66, it can be ensured that the adjusting rod 64 can move back and forth to achieve the effect of pushing or pulling the piston plate 63 to move back and forth. At the same time, it can be ensured that the adjusted rod body 641 can be fixed after rotation with the cooperation of the positioning blocks 642 and the fixing ring 2, thereby ensuring that the adjusted rod 64 and the piston plate 63 remain fixed after movement.
[0031] Working principle and usage process of this utility model:
[0032] After the patient lies down, place their head on several fixed airbags 3 inside the fixed ring 2. After determining the sleeping position and the angle of the head, rotate the fastening bolt 53 to fix the positioning slider 51 through the positioning slide rod 52 with the cooperation of the slide groove 41 and the limiting groove 42, thereby keeping the relative angle between the fixed ring 2 and the support fixed seat 1 fixed, thus fixing the angle of the head.
[0033] Then, push the adjusting rod body 641 to push the piston plate 63 along the inside of the adjusting cavity 61. The piston plate 63 then forces the air in the adjusting cavity 61 on its back through the connecting hole 62 into the interior of several fixed airbags 3, causing the several fixed airbags 3 to expand simultaneously. This gradually reduces the distance between the several fixed airbags 3, thereby fixing the position of the head. Then, rotate the adjusting rod body 641 to make the positioning block 642 and the adapter port 66 misaligned, thus maintaining the stability of the adjusting rod 64.
