[0002] During radiotherapy for nasopharyngeal carcinoma, limited oral opening is a common complication. This may be due to swelling, fibrosis and adhesion of the oral mucosa caused by radiotherapy. To cope with this situation, mouth opening exercises are widely used before, during and after radiotherapy. The purpose of mouth opening exercises is to increase the range of oral opening through specific oral exercises and traction techniques.

[0003] In order to evaluate the degree of mouth opening restriction, doctors often use a vernier caliper or ruler to measure the patient's maximum mouth opening. This traditional method is affected by the operator's subjective judgment, and different operators are prone to obtaining different measurement results, resulting in errors. In addition, since the patient's physical condition is not good after surgery and the maximum mouth opening cannot be maintained continuously, it is impossible to guarantee that the maximum mouth opening can be detected during the test, which affects the test data.

[0027] The rear end of the outer wall of the connecting rod 8 is fixedly connected with a spur tooth plate 11, and the rear end of the spur tooth plate 11 is meshed with an outer tooth ring 12 on the outer wall. The inner wall of the outer tooth ring 12 is provided with a ratchet groove 13, and the rear side of the opposite end of the slide tube 5 is rotatably connected with a pawl 15 through a torsion spring 14. The bottom end of the connecting rod 8 is installed on the top of the bottom connecting block 3 through a return spring 16. The opposite ends of the torsion spring 14 are respectively fixedly connected to the rear side of the opposite end of the slide tube 5, and the opposite ends of the torsion spring 14 are respectively fixedly connected to the opposite end of the pawl 15. The bottom ends of the return springs 16 are fixedly connected to the top of the bottom connecting block 3, and the top ends of the return springs 16 are fixedly connected to the bottom end of the connecting rod 8. The left and right ends of the outer tooth ring 12 are rotatably connected to the outer wall of the rear end of the slide tube 5. After the device is worn, the mouth begins to open, and the return spring 16 will allow the connecting rod 8 to stably lift the upper jaw plate 2 through its own elastic force, so that the upper jaw plate 2 fits the patient. The upper jaw when opening the mouth, and when the connecting rod 8 moves, the outer tooth ring 12 is driven to rotate through the straight tooth plate 11. After the patient maintains the maximum mouth opening, the patient's upper jaw fixes the upper jaw plate 2, and the upper jaw plate 2 stops the connecting rod 8 from moving, and under the elastic force of the torsion spring 14, the pawl 15 is stuck in the ratchet groove 13, so that the outer tooth ring 12 cannot rotate after rotating, so that the outer tooth ring 12 fixes the straight tooth plate 11, and the straight tooth plate 11 fixes the rising height of the connecting rod 8, and with the cooperation of the indicator rod 10 and the grading groove 9, the patient's maximum mouth opening size can be detected, and under the action of the timer 7, the patient's mouth opening time can be detected, so that when the medical staff performs the test, the patient's maximum mouth opening size can be stably detected, thereby improving the accuracy of the test data, facilitating corresponding treatment according to the patient's physical data, and helping the patient to recover.

[0028] The fixing blocks 4 at the upper and lower ends are fixedly connected with a connecting rope 17 at one end opposite to the other, and the adjusting shell 6 is threadedly connected with an adjusting bolt 18 at one end opposite to the other. The adjusting bolt 18 is rotatably connected with an extrusion block 19 at one end. The upper and lower sides of the inner wall of the opposite end of the adjusting shell 6 are slidably connected with clamping blocks 20. The front and rear ends of the extrusion block 19 are slidably connected to the front and rear ends of the inner wall of the adjusting shell 6. When wearing the device, the lower jaw plate 1 and the upper jaw plate 2 are placed in the patient's oral cavity, and then the adjusting bolt 18 is rotated so that the adjusting bolt 18 drives the extrusion block 19 to move along the adjusting shell 6, so that the clamping block 20 reduces the fixation of the connecting rope 17 due to gravity. When the adjusting shell 6 is adjusted to a suitable position, the adjusting bolt 18 is rotated in the opposite direction so that the extrusion block 19 squeezes the clamping block 20, so that the clamping block 20 fixes the connecting rope 17, so that the patient can wear it conveniently when using it, improve the convenience of using the device, and allow patients to perform detection more conveniently, reduce the burden on medical staff, and help to improve patients' participation and enthusiasm in treatment.

[0029] Working principle: First, when wearing the device, place the lower jaw plate 1 and the upper jaw plate 2 in the patient's oral cavity, and then rotate the adjusting bolt 18 so that the adjusting bolt 18 drives the squeezing block 19 to move along the adjusting shell 6, so that the clamping block 20 reduces the fixation of the connecting rope 17 due to gravity. After the adjusting shell 6 is adjusted to a suitable position, rotate the adjusting bolt 18 in the opposite direction so that the squeezing block 19 squeezes the clamping block 20, and the clamping block 20 fixes the connecting rope 17, making it convenient for patients to wear it, improving the convenience of using the device, allowing patients to perform tests more conveniently, reducing the burden on medical staff, and helping to improve patients' treatment participation and enthusiasm. After the device is worn, start to open the mouth, and the reset spring 16 will use its own elastic force to allow the connecting rod 8 to stably lift the upper jaw plate 2, so that the upper jaw plate 2 fits the upper jaw of the patient when opening his mouth. When the connecting rod 8 moves, the outer tooth ring 12 is driven to rotate through the spur plate 11. After the patient maintains the maximum mouth opening, the patient's upper jaw fixes the upper jaw plate 2, and the upper jaw plate 2 stops the connecting rod 8 from moving, and under the elastic force of the torsion spring 14, the pawl 15 is stuck in the ratchet groove 13, so that the outer tooth ring 12 cannot rotate after rotating, so that the outer tooth ring 12 fixes the spur plate 11, and the spur plate 11 fixes the rising height of the connecting rod 8, and with the cooperation of the indicator rod 10 and the grading groove 9, the patient's maximum mouth opening size can be detected, and under the action of the timer 7, the patient's mouth opening time can be detected, so that when the medical staff performs the test, the patient's maximum mouth opening size can be stably detected, thereby improving the accuracy of the test data, facilitating corresponding treatment according to the patient's physical data, and helping the patient to recover.
