Specifically, one end of the main body 1 is provided with an upper bite pad 2 and a lower bite pad 3, that is, the upper bite pad 2 and the lower bite pad 3 are correspondingly arranged on the longitudinal portion of the main body 1. Wherein, the upper occlusion pad 2 is fixedly arranged; the head ends of the lower bite pad 3 and the control arm 4 are provided with a connecting rod 8. The upper bite pad 2 is for contacting upper teeth in the oral cavity, and the lower bite pad 3 is for contacting lower teeth in the oral cavity.
In this embodiment, the upper bite pad 2 and the lower bite pad 3 are respectively provided with a pressure sensor 7 for collecting pressure data of the upper jaw and the lower jaw of the oral cavity of the patient.
It should be noted that, the existing mouth-opening rehabilitation device does not have a pressure detection device, so that the patient can only sense whether the patient is painful or not or the mouth-opening angle during mouth-opening training. However, the pain of the patient is not accurate enough for the doctor to judge the rehabilitation effect or to set the training gape. And most of the mouth-opening rehabilitators are simple mechanical structures, and no space or foundation is provided for adding the pressure sensor 7. The pressure data is displayed through the LED screen 6, pain assessment can be performed by a doctor when a patient is subjected to mouth opening training, the degree of mouth opening of training can be adjusted, the degree of rehabilitation is assessed, and the mouth opening training effect is easy to measure by the doctor.
Preferably, an angle scale is arranged on the main body 1 corresponding to the part between the upper bite pad 2 and the lower bite pad 3, so as to know the mouth opening degree of the patient during training.
In one embodiment of the present application, the materials of the upper bite pad 2 and the lower bite pad 3 include, but are not limited to: any one of foam, polylactic acid, nylon plastic, photosensitive resin, silica gel, rubber, latex, ABS plastic, PVC plastic, organic silicon resin and propenyl resin.

While the head end of the control arm 4 (i.e. the transverse part close to the main body 1) is mainly used for controlling the longitudinal swing of the lower bite pad 3, and the tail end of the control arm 4 (i.e. the transverse part far from the main body 1) is mainly used for limiting the moving distance or angle of the control arm 4.
Specifically, the upper bite pad 2 is fixedly arranged; the head ends of the lower bite pad 3 and the control arm 4 are provided with a connecting rod 8.
In an embodiment of the present application, the head end of the control arm 4 is connected to one end of the connecting rod 8; the other end of the connecting rod 8 is fixedly connected with the tail end of the lower occlusion pad 3 positioned in the main body 1 in a shaft pin fixing or screw fixing mode; the lower bite pad 3 is also provided with a fixing member 9 or a fixing pile below the end located in the body 1. When the head end of the control arm 4 is pressed, the connecting rod 8 drives the lower bite pad 3 to move downwards, and the fixing part 9 enables the part of the lower bite pad 3, which is positioned outside the main body 1, to swing downwards.
For example, when the device is used, the top of the main body 1 is pressed to be close to the upper bite pad 2 and the lower bite pad 3, the shell of the main body 1 at the position is movable, force can be transmitted to the control arm 4, the connecting rod 8 is driven to correspondingly move downwards, and the lower bite pad 3 is driven to swing downwards under the action of the fixing piece 9, so that the upper bite pad 2 and the lower bite pad 3 are opened at a certain angle in the oral cavity of a patient, and the oral cavity of the patient is helped to be opened at a certain angle. Specifically, the jaw muscle group rehabilitation device can help to exercise the mouth opening and closing actions of a patient by repeatedly pressing or loosening, so that the effects of relieving jaw muscle groups, recovering and adapting after operation, relieving swelling or pain and the like are achieved.
In an embodiment of the present application, a longitudinally disposed spring 11 is disposed at the rear end of the control arm 4; when the head end of the control arm 4 is released, the spring 11 rebounds the control arm 4 to the initial position, and the connecting rod 8 drives the part of the lower engagement pad 3 outside the main body 1 to swing back to the initial position.
In this embodiment, the other end of the main body 1 is provided with a fine adjustment knob 5 for limiting the moving distance or angle of the control arm 4.
In one embodiment of the present application, the fine adjustment knob 5 is disposed horizontally, and a threaded rod 10 disposed longitudinally is disposed between the fine adjustment knob and the tail end of the control arm 4; the part of the fine adjustment knob 5, which is positioned outside the main body 1, is a disc type knob, and the part, which is positioned inside the main body 1, is a cylinder with threads and is engaged with the threads of the threaded rod 10 in a matching way; when the fine adjustment knob 5 is rotated, the threaded rod 10 can move up and down through thread engagement, and the control arm 4 is driven to move up and down, so that the moving distance or angle of the control arm 4 is limited.
For example, when the fine adjustment knob 5 is rotated a certain amount, the threaded rod 10 is lifted a certain distance, which reduces the up-and-down movable space of the control arm 4, so that the movable range of the control arm 4 is reduced, and the corresponding amplitude for controlling the longitudinal swing of the lower bite pad 3 is also reduced.
Optionally, the fine adjustment knob 5 is further provided with a function of locking or locking the control arm 4 to fix the longitudinal swing posture of the lower bite pad 3. For example, when the user presses the head end of the control arm 4 into position, the fine adjustment knob 5 is rotated, causing the threaded rod 10 to press the tail end of the control arm 4 to the lowest position, thereby limiting the rebound of the spring 11 to effect the securing of the integral control arm 4 and thus the lower bite pad 3. Therefore, the patient can be trained to have a fixed mouth opening angle by fixing the angles of the upper occlusal pad 2 and the lower occlusal pad 3.

The LED screen 6 is used for displaying the pressure data collected by the pressure sensor 7, so that after the device is used again, a doctor or a patient can adjust the strength of the control arm 4 or evaluate the pain degree and evaluate the rehabilitation degree according to the pressure data.
Preferably, the LED screen 6 is not limited to displaying pressure data, but may also display mouth opening angle, training times, and the like. For example, an angle sensor or an infrared distance meter is further arranged on the lower occlusion pad 3 to collect and represent the data of the opening degree between the upper occlusion pad 2 and the lower occlusion pad 3, and the data is displayed by the LED screen 6. As another example, the LED screen 6 may also display the corresponding number of training sessions by recording the number of times of the pressure data.
