[0002] Oral diagnosis and treatment is a very important part of modern medicine. During the treatment process, dentists often need to use an opener to keep the patient's mouth in a specific position and angle in order to better diagnose and treat.

[0003] For example, the prior art disclosed in CN117503033A discloses a mouth opener, comprising a rectangular shell, a cavity structure inside the rectangular shell, a rectangular through hole on the side wall of the rectangular shell, a door matching the rectangular through hole connected to the rectangular shell by a hinge, a stretching and expansion structure on the rectangular shell, and a lip expansion structure on the stretching and expansion structure. The beneficial effect of the present invention is that the upper and lower tooth support plates are extended and placed in the oral cavity by the stretching and expansion structure, and the upper and lower teeth are stretched open by the upper and lower tooth support plates, the oral cavity is opened, and after the oral cavity is opened, the opening angle is maintained, and the angle can be adjusted outside the mouth.

[0004] Another typical oral opener disclosed in the prior art of CN107157434A includes a handle. When in use, the upper surface of the upper support plate is first brought into contact with the lower surface of the upper teeth, so that the lower support plate extends into the oral cavity and is located above the lower teeth. According to the degree of opening of the patient's mouth, the connecting rod is pressed to compress the reset spring, so that the vertical rod moves downward, driving the lower support plate to move downward, so that the lower surface of the lower support plate contacts the upper surface of the lower teeth, so that the patient's mouth shape positioning can be achieved. After the examination or diagnosis is completed, the connecting rod is loosened to reset the reset spring, so that the lower support plate is separated from the lower teeth, and then the upper and lower support plates can be taken out of the oral cavity.

[0005] Let's look at the oral opener disclosed in the prior art CN108836246A, which includes a frame body, a jaw plate and a tongue guard adjustment assembly installed on the frame body, and the jaw plate and the tongue guard adjustment assembly are respectively installed at opposite ends of the frame body; the tongue guard adjustment assembly includes a support rod, a telescopic rod sleeved in the support rod, a first fixing bolt connecting the telescopic rod and a tongue guard, and the first fixing bolt drives the telescopic rod and the tongue guard to move laterally.

[0027] Specifically, the end of the connecting end is arranged inside the adjusting part 4, and a fixing element is arranged inside the adjusting part 4. The fixing element communicates with the user terminal signal. When the user adjusts the angle of the tongue depressor 5, a fixing signal is sent to the fixing element through the user terminal, so that the fixing element fixes the end of the connecting end.

[0031] Furthermore, it also includes a miniature air compressor 14, the connecting part includes an air vent 7, a connecting valve and an air inlet pipe 13, the air vent 7 includes an air inlet 71 and an air outlet 72, the air inlet 71 is connected to the air inlet 91, the air outlet 72 is connected to the exhaust port, the connecting valve is arranged at the air inlet 71 and the air outlet 72, the connecting valve is used to control the opening and closing of the air inlet 91 and the air outlet 72, the air inlet pipe 13 is detachably installed on the air inlet 71, one end of the air inlet pipe 13 is connected to the air inlet 71, and the other end is connected to the miniature air compressor 14, the air inlet pipe 13 is used to transport compressed air to the air inlet 91.

[0032] Specifically, a magnetic element is provided inside the piston rod 12, and the adjustment module is provided with a detection element 10. The detection element 10 is used to detect the position of the magnetic element. The detection element 10 is in signal communication with the connecting valve, the solenoid valve and the user terminal. When the detection element 10 detects that the piston rod 12 (magnetic element) moves to a specified position, the detection element 10 sends a stop signal to the connecting valve, the solenoid valve and the user terminal. After receiving the stop signal, each valve is closed, and the user terminal reminds the user that the adjustment has ended.

[0033] Specifically, the volume of the micro air compressor 14 is 5 cubic centimeters to 30 cubic centimeters.

[0034] Specifically, the use process of the mouth opener is as follows:

[0035] STEP 1, put the mouth opener between the patient's lips and teeth, and the doctor sends an adjustment signal to the solenoid valve, the connecting valve and the detection element 10 through the user terminal according to the size of the patient's mouth, and connects the air inlet pipe 13 to the air inlet 91;

[0036] Specifically, the adjustment signal includes information of the target moving distance of the adjustment unit 4;

[0037] STEP2, all the connecting valves are fully opened, the solenoid valve at the exhaust port 92 is fully opened, and the solenoid valve at the air inlet 91 adjusts its opening according to the adjustment algorithm;

[0038] STEP 3, the micro air compressor 14 delivers the gas to the air inlet 71 through the air inlet pipe 13 and further delivers the gas to the air inlet 91. The gas is delivered to the cylinder through the air inlet 91, and the cylinder drives the piston rod 12 to move;

[0039] STEP 4, the detection element 10 detects the moving distance of the piston rod 12, and when the moving distance of the piston rod 12 meets the target moving distance information involved in the adjustment signal, a stop signal is sent to the communication valve, the solenoid valve and the user terminal;

[0040] STEP5, close the connecting valve and the solenoid valve, and remove the intake pipe 13;

[0041] STEP 6, adjust the angles of the tongue depressor 5 and the mouth angle expander 6, and fix the mouth opener in the patient's mouth.

[0042] Specifically, it also includes a method for controlling the moving speed of the adjustment part 4 through a solenoid valve. The method obtains the target moving speed of the adjustment part 4 according to the target moving distance of the adjustment part 4, and obtains the target opening of the solenoid valve according to the target moving speed. By controlling the opening of the solenoid valve (that is, the cross-sectional area of ​​the air inlet 91), the gas flow in and out of the cylinder is controlled, and then the moving speed of the piston rod 12 is controlled through the cylinder, and the moving speed of the adjustment part 4 is controlled through the piston rod 12. The method adjusts the cross-sectional area of ​​the air inlet 91 through an adjustment algorithm, and the adjustment algorithm satisfies the following formula:

[0043]

[0044] Wherein, v is the target moving speed of the adjustment unit 4, v set is the preset speed of the adjustment unit 4, D is the target moving distance of the adjustment unit 4, and D set is the moving distance parameter of the adjustment part 4, which is set by a person skilled in the art, and the value may be 10 mm, e is a natural constant, and S in is the cross-sectional area of ​​the air inlet 91, S is the cross-sectional area of ​​the cylinder, C is the flow coefficient of the solenoid valve, which is determined by the model of the solenoid valve and can generally be provided by the manufacturer or obtained through actual experiments, p is the density of the gas passing through the air inlet 91, P in is the pressure of the gas passing through the gas inlet 91.

[0045] Specifically, during the movement, the solenoid valve controlling the exhaust port 92 remains in a fully open state.

[0046] The beneficial effects of this solution are: 1. The adjustment module is used to control the movement of the adjustment part 4, thereby adjusting the width of the support frame. Compared with the manual adjustment of the prior art, it has higher accuracy and does not require the frame to be fixed after each adjustment, which helps to reduce the complexity of the operation.

[0047] 2. By setting the target moving speed of the adjustment part 4 and changing the cross-sectional area of ​​the air inlet 91 according to the target moving speed, it is helpful to reduce the moving speed of the adjustment part 4 when the target moving distance is large, which is helpful to reduce the discomfort caused by the adjustment to the patient and to avoid loosening and falling off due to too fast movement.
