[0020] Referring to Figure 1-2 , an intelligent automatic precise minimally invasive distraction osteogenesis system includes an adjusting rod 1. A fixing mechanism is sleeved on the adjusting rod 1. The fixing mechanism includes an adjusting block 2 sleeved on the adjusting rod 1. A 360-degree panoramic camera is connected to the side wall of the adjusting block 2. A signal transmitter is arranged in the adjusting rod 1. The 360-degree panoramic camera can take pictures of the patient's face, and the signal transmitter can send the relevant pictures to the doctor's background data, which further facilitates the doctor to grasp the patient's situation.

[0021] A controller 18 is fixedly connected to the upper end of the adjusting block 2. Two moving rods 3 penetrate through the side wall of the adjusting block 2. Clamping plates 4 are arranged at both ends of the adjusting block 2. A plurality of sensors are arranged on the side wall of the clamping plate 4. When the sensors contact the patient's face, the alarm will emit light, further reminding the patient and other personnel, avoiding the phenomenon of the device being not firmly fixed. Two symmetrically arranged infrared detectors 17 are fixedly connected to the side wall of the clamping plate 4. The number of the infrared detectors 17 is two. An anti-collision infrared inductor is connected to the side wall of the infrared detector 17, thus avoiding other people hitting the infrared detector 17 and further protecting the infrared detector 17. The infrared detector 17, the camera 8 and the controller 18 are electrically connected. The infrared detector 17 and the camera 8 can photograph the face, tooth changes, implement recording of traction parameter changes, face and tooth changes, and the activity status of the patient and other software systems, and can transmit them back to the doctor's terminal.

[0022] The left and right ends of the two moving rods 3 respectively pass through the two clamping plates 4 and extend to the outside thereof. The two clamping plates 4 can move freely left and right through the moving rods 3. A fixing nut is sleeved on one end of the moving rod 3, further limiting the movement of the clamping plate, thus ensuring the stability of the device and avoiding the shaking of the device. At the same time, scales are marked on the moving rod 3. The midpoint of the rod is "0", and "mm" and "cm" scales are marked in sequence from this origin to the left and right sides respectively. According to the size of the skull, the left and right clamping plates 4 can slide left and right on the moving rod 3. After the inverted "U" - shaped fixing frame is adjusted to be suitable for the patient's individual head shape, the purpose of fixing the device is achieved.

[0023] A plurality of fixing bolts 5 are threadedly connected to the side walls of the two clamping plates 4. Threaded holes are arranged on the side walls of the clamping plates 4, and the threaded holes are threadedly connected with the fixing bolts 5. The specific shape of the fixing bolt 5 is that the tip of the fixing bolt is flat, with a height of 2 mm, a bottom diameter of 3 mm, followed by the neck of the bolt, which is a cuboid with a width of 3 mm, a thickness of 2 mm, and a length of 5 mm, and then followed by a threaded cylinder with a diameter of 4.5 mm and a height of 5 cm. The flat tip of the fixing bolt 5 can make the skin incision smaller, the scar and hair loss area smaller after the postoperative wound heals, and can also reduce the pain of the patient.

[0024] A moving mechanism is sleeved on the adjusting rod 1. The moving mechanism includes a regulating block 6 sleeved on the adjusting rod 1. A moving bolt 16 is threadedly connected to the side wall of the regulating block 6. A threaded hole is arranged on the side wall of the regulating block 6, and the threaded hole is threadedly connected with the moving bolt 16. One end of the moving bolt 16 passes through the side wall of the regulating block 6 and contacts the adjusting rod 1. A cross - block 7 is fixedly connected to the side wall of the regulating block 6.

[0025] The side wall of the adjusting rod 1 is fixedly connected with a camera 8, and the camera 8 is electrically connected to an external signal source. The camera 8 can capture facial and dental changes, and transmit data such as the implementation record of traction parameter changes, facial and dental changes, and the activity status of the patient back to the doctor's terminal, which has the characteristic functions of Internet medical care. This is the prior art and will not be elaborated here. The side wall of the cross block 7 is connected to a rotating mechanism, and the moving mechanism is electrically connected to an external signal source.

[0026] A rotating mechanism is connected to the side wall of the moving mechanism. The rotating mechanism includes a cross plate 9 fixedly connected to the side wall of the cross block 7. Two vertical plates 19 are fixedly connected to the upper end of the cross plate 9. Servo motors 20 are fixedly connected to the upper ends of the two vertical plates 19. At the same time, the servo motors 20 are electrically connected to a controller 18. The controller 18 can start the servo motors according to the face shape changes and dental changes captured by the infrared detector 17 and the camera 8, so as to adjust the screws on the left and right regulators to increase or decrease the traction force on one side. Fixed shafts 21 are fixedly connected to the drive shafts of the two servo motors 20. First gears 22 are coaxially fixedly connected to one ends of the two fixed shafts 21.

[0027] A fixed long rod 10 penetrates through the side wall of the cross plate 9. Two adjusting bolts 11 are slidably connected to the side wall of the cross plate 9. Second gears 23 are threadedly connected to the side walls of the two adjusting bolts 11. Fixed rings 24 are rotatably connected to the side walls of the two second gears 23. The two first gears 22 are respectively engaged with the two second gears 23. The fixed rings 24 are fixedly and slidably connected to the adjusting bolts 11. A regulating mechanism is connected to the two adjusting bolts 11.

[0028] A regulating mechanism is connected to the side wall of the rotating mechanism. The regulating mechanism includes adjusting nut covers 12 respectively fixedly connected to the side walls of the two adjusting bolts 11. An indicating disk 13 is rotatably connected to the side walls of the two adjusting nut covers 12. When the adjusting bolt 11 is rotated, the arrow on the rotating needle 14 indicates the number of turns of rotation on the indicating disk. For every one turn of rotation of the rotating needle 14, the traction spring is stretched by 0.5 mm.

[0029] Rotating needles 14 are provided on the side walls of both of the two indicating disks 13. The two rotating needles 14 are respectively fixedly connected to the two adjusting nut covers 12. One end of each of the two adjusting bolts 11 away from the adjusting nut cover 12 is fixedly connected with a traction spring 15. For every 1 mm of stretching of the traction spring 15, it is a force of 250 grams. The traction spring 15 is used in cooperation with a traction hook. The traction hook is a prior art and is designed into two parts. One part is a hook section, which is placed in the canine pillar of the maxilla. The end of the hook protrudes from the front of the maxilla. The other end surface has threads and extends out of the nasal vestibule. The other part is divided into a rear section and a front end. The rear section is a hollow tube with threads on the inner surface thereof, and is screwed to the nasal cavity section of the hook section through threading. The front end is an open ring and is directly connected to the hook end of the traction spring 15.

[0030] In the present invention, when a staff member needs to use this device, first, the staff member can move the height of the adjusting block 2 on the adjusting rod 1, and further move the adjusting block 2 to a suitable position. Then, the staff member adjusts the distance between the two clamping plates 4 according to the size of the patient's head, and fixes the clamping plates 4 through the nuts on the moving rod 3. After the positions of the two clamping plates 4 are adjusted, the staff member can rotate the fixing bolt 5 to further fix the device on the patient's head.

[0031] Then, the staff member can fix the device on the traction hook through one end of the traction spring 15, and then insert the traction hook into the patient's body. At the same time, according to the use of the infrared detector 17 and the controller 18, data such as facial images, tooth changes, implementation record of traction parameter changes, facial and tooth changes, and the activity state of the patient can be obtained. Then, the controller 18 can start the servo motor 20. When the servo motor 20 works, the rotating shaft 21 can rotate. When the rotating shaft 21 rotates, the first gear 22 can rotate. When the first gear 22 rotates, the second gear 23 can rotate. Since the second gear 23 is threadedly connected to the adjusting bolt 11, and the fixing ring 24 can limit the rotation of the adjusting bolt 11, the adjusting bolt 11 will move accordingly, and further the force of the traction spring 15 can be adjusted. When the adjusting bolt 11 is rotated.

[0032] The arrow on the rotating needle 14 indicates the number of rotation circles at the position of the indicating disk. For every one rotation of the rotating needle 14, the traction spring is stretched by 0.5 mm. At the same time, for every 1 mm of stretching of the traction spring 15, it is a force of 250 grams, which further facilitates the staff member to more accurately control the force generated by the traction spring 15.

[0033] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
