[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please refer to the following: Figures 1-7The head immobilization device for pediatric patients includes: a base plate 1, a headrest 2 made of silicone placed on top of the base plate 1, and an arc-shaped limiting groove on the upper part of the headrest 2. Two side frames 4 are mounted on the base plate 1, and the side frames 4 are approximately inverted U-shaped. Each side frame 4 is equipped with an adjustable side fixation mechanism for fixing the patient's head on both sides. An arc-shaped slide rail 11 and an arc-shaped plate 14 are also mounted on the top of the base plate 1. The arc-shaped slide rail 11 is located inside the arc-shaped plate 14 and is slidably installed inside the arc-shaped slide rail 11. There is an arc-shaped slider 12, and an L-shaped fixing frame 13 is fixedly installed on the top of the arc-shaped slider 12. The L-shaped fixing frame 13 is provided with an adjustable upper fixing mechanism, which is used to fix the patient's forehead. The top of the arc plate 14 has multiple slots 1401. A threaded rod 15 is threadedly installed on the arc-shaped slider 12. The bottom end of the threaded rod 15 extends into one of the slots 1401. The L-shaped fixing frame 13 can slide on the arc-shaped slide rail 11 through the arc-shaped slider 12 to adjust its own position.

[0023] In this embodiment, the top of the base plate 1 is provided with an installation groove, and a detachable plate 3 is provided in the installation groove. The two side frames 4, the arc slide rail 11 and the arc plate 14 are all fixedly installed on the top of the detachable plate 3. Two fixed shafts 23 are fixedly installed on the top of the base plate 1. The top of each of the two fixed shafts 23 is rotatably fitted with a rotation limiting plate 24. The bottom of each of the two rotation limiting plates 24 is in contact with the top of the detachable plate 3. After rotating the two rotation limiting plates 24 to the sides by a certain degree, the rotation limiting plates 24 can be separated from the detachable plate 3, thereby releasing the restriction on the detachable plate 3, and then the detachable plate 3 can be removed.

[0024] In this embodiment, in order to position the detachable plate 3, four positioning shafts arranged in a rectangular array are fixedly installed on the bottom inner wall of the mounting groove. The detachable plate 3 has four positioning holes, and the four positioning shafts pass through the corresponding positioning holes and slide to connect with the inner wall of the corresponding positioning holes. The end face of the top of the positioning shaft is rounded at the connection with the outer peripheral wall to facilitate easy insertion into the positioning hole.

[0025] In this embodiment, the adjustable side fixation mechanism includes a sliding rod 5, two first limiting slide rods 6, a side clamp 7, a first adjusting screw 8, and a first silicone sleeve 9. The sliding rod 5 has a square sliding opening, through which it is slidably fitted onto the side frame 4. The sliding rod 5 can move left or right on the side frame 4 to flexibly adjust the fixation position on the side of the patient's head. Both first limiting slide rods 6 are slidably mounted on the sliding rod 5. The side clamp 7 is fixedly mounted on one end of the two first limiting slide rods 6 near the curved slide rail 11. The first adjusting screw 8 passes through and is threaded onto the sliding rod 5. One end of the first adjusting screw 8 is rotatably connected to the side clamp 7. During the clockwise or counterclockwise rotation of the first adjusting screw 8, it will move forward or backward, thereby driving the side clamp 7 to move accordingly. The first silicone sleeve 9 is fixedly sleeved on the side clamp 7. The top of the sliding rod 5 is threaded with a clamping screw 10. The bottom end of the clamping screw 10 contacts the side frame 4. After applying sufficient preload to the clamping screw 10, its bottom end can press against the side frame 4, thereby fixing the sliding rod 5.

[0026] In this embodiment, the adjustable upper fixing mechanism includes an I-shaped slider 16, two second limiting slide rods 17, a pressure plate 18, a second adjusting screw 19, a second silicone sleeve 20, a fixing block 21, and a third adjusting screw 22. The top of the L-shaped fixing frame 13 has a strip-shaped sliding opening. The I-shaped slider 16 is slidably installed within the strip-shaped sliding opening. The upper and lower wing plates of the I-shaped slider 16 are located above and below the strip-shaped sliding opening, respectively, for limiting the movement of the I-shaped slider 16. Both second limiting slide rods 17 pass through and are slidably installed on the I-shaped slider 16. 6. The pressure plate 18 is fixedly installed at the bottom of the two second limiting slide rods 17. The second silicone sleeve 20 is fixedly sleeved on the pressure plate 18. The fixing block 21 is fixedly installed on the top of the L-shaped fixing frame 13. The third adjusting screw 22 passes through and is threaded onto the fixing block 21. One end of the third adjusting screw 22 is rotatably connected to the I-shaped slider 16. By rotating the third adjusting screw 22 clockwise or counterclockwise, it moves forward or backward, thereby driving the I-shaped slider 16 to move accordingly. This can adjust the fixed position on the patient's forehead.

[0027] In this embodiment, an anti-slip pad is fixedly installed on the bottom of the base plate 1. The anti-slip pad is made of silicone. By setting the anti-slip pad, the friction between the base plate 1 and the operating table mattress can be increased, preventing it from moving at will. Two mounting holes are also opened on the base plate 1. In some applicable scenarios, the base plate 1 can be fixed to the operating table board with screws.

[0028] The working principle of the head-supporting fixation device for pediatric patients provided by this utility model is as follows:

[0029] When in use, this device is placed on the mattress of the operating table. The child patient's head is first placed on the headrest 2, and then the removable plate 3 is installed.

[0030] When installing the removable plate 3, align the four positioning holes on the removable plate 3 with the four positioning shafts and put it down. After the removable plate 3 is in place, the child patient's head is between the two side clamps 7, and the pressure plate 18 is above the child patient's head. Then, rotate the two rotating limiting plates 24 to the top of the removable plate 3 in turn, so that the removable plate 3 is limited.

[0031] Then, turn the two first adjusting screws 8 clockwise in sequence. As the first adjusting screws 8 rotate clockwise, they will gradually move towards the patient's head. The first adjusting screws 8 drive the side clamps 7 to move until the first silicone sleeve 9 on the side clamps 7 fits against the side of the patient's head. The two side clamps 7 work together to restrict the sides of the patient's head and prevent the patient's head from shifting to the left or right. When fixing, if the patient's treatment position is on the side of the head, the clamping position of the two side clamps 7 should be adjusted according to the treatment position before fixing. The purpose is to avoid the treatment position. When adjusting, first turn the tightening screw 10 counterclockwise to separate its bottom end from the side frame 4. Then, the position of the side clamps 7 can be adjusted to the left or right by pushing the sliding rod 5. After the position is determined, tighten the tightening screw 10 clockwise.

[0032] After fixing both sides of the child patient's head, turn the second adjusting screw 19 clockwise to move it downwards. The second adjusting screw 19 drives the pressure plate 18 to move, so that the second silicone sleeve 20 on the pressure plate 18 can fit tightly against the patient's forehead. If the patient's treatment position is on the forehead, the position of the pressure plate 18 can be adjusted by turning the third adjusting screw 22 clockwise or counterclockwise to avoid the treatment position on the forehead. If the initial position of the L-shaped fixation frame 13 will affect the surgical operation, its position can be adjusted before the operation. When adjusting, first turn the threaded rod 15 counterclockwise. When the bottom end of the threaded rod 15 is completely removed from the previous slot 1401, the fixation of the arc-shaped slider 12 is released. Then, it can slide circumferentially along the arc-shaped slide rail 11. After it is in the right position, turn the threaded rod 15 clockwise again so that the bottom end of the threaded rod 15 is inserted into the slot 1401 corresponding to the current position.
