[0046] Taking into account the differences in sensitivity of patients of different age groups to bronchoscopes, the bronchoscope simulation device of this embodiment has a variety of setting programs to adapt to patients of different age groups. Exemplarily, the setting program includes a first-level setting program, a second-level setting program, and a third-level setting program. The first-level setting program is suitable for the elderly, with an opening and closing rate of 12 times / minute, and a spacing of 1 cm between the first splint 62 and the second splint 72 when they move in opposite directions; the second-level setting program is suitable for middle-aged people, with an opening and closing rate of 16 times / minute, and a spacing of 1.5 cm between the first splint 62 and the second splint 72 when they move in opposite directions; the third-level setting program is suitable for teenagers, with an opening and closing rate of 20 times / minute, and a spacing of 2 cm between the first splint 62 and the second splint 72 when they move in opposite directions.

[0048] The working principle and operation process of the bronchoscope simulation device are as follows:

[0049] When using the device, the bronchoscope is inserted through the nostrils of the model, and the device is placed at the throat of the model, and the microcontroller is installed on the outside of the model; when the subject to be tested is an elderly person, the program is switched to the first gear setting program to control the stepper motor 2 to rotate forward, at which time the first rack 22 and the second rack 23 can be driven to move relative to each other, and when the first rack 22 and the second rack 23 move relative to each other, the first slider 4 and the second slider 5 can be driven to move relative to each other, and then the first pad 6 and the second pad 7 can be driven to move relative to each other, and finally the first splint 62 and the second splint 72 can be driven to move relative to each other, and when the first splint 62 and the second splint 72 are in contact, the first electromagnet 63 and the second electromagnet 73 are attracted to each other, and when the upper bronchoscope abuts against the first electromagnet 63 When the first and second electromagnets 73 are on, the first and second electromagnets 63 and 73 can be compressed. At this time, the first sensor 61 and the second sensor 71 can receive corresponding pressure values. When the pressure values ​​reach the specific values ​​for the elderly on the microcontroller, the microcontroller controls the stepper motor 2 to reverse, which can drive the transmission gear 21 to reverse. After the transmission gear 21 reverses, it can drive the first rack 22 and the second rack 23 to move in opposite directions. When the first rack 22 and the second rack 23 move in opposite directions, it can drive the first slider 4 and the second slider 5 to move in opposite directions, and then drive the first pad 6 and the second pad 7 to move in opposite directions. Finally, it can drive the first splint 62 and the second splint 72 to move in opposite directions until the first splint 62 and the second splint 72 move in opposite directions. It only needs to be moved to 1 cm. At this time, it is convenient for the upper bronchoscope to pass between the first splint 62 and the second splint 72, which is convenient for subsequent operations. When the object to be tested is a middle-aged person, the stepper motor 2 is controlled to rotate forward and switched to the second gear setting program. At this time, the first rack 22 and the second rack 23 can be driven to move relative to each other. When the first rack 22 and the second rack 23 move relative to each other, the first slider 4 and the second slider 5 can be driven to move relative to each other, and then the first pad 6 and the second pad 7 can be driven to move relative to each other. Finally, the first splint 62 and the second splint 72 can be driven to move relative to each other. When the first splint 62 and the second splint 72 are in contact, the first electromagnet 63 and the second electromagnet 73 are attracted to each other. When the upper bronchoscope is against the first electromagnet 63 and the second electromagnet When the iron 73 is on, the first electromagnet 63 and the second electromagnet 73 can be compressed. At this time, the first sensor 61 and the second sensor 71 can receive the corresponding pressure value. When the pressure value reaches the specific value for middle-aged people on the microcontroller, the microcontroller controls the stepper motor 2 to reverse, and then drives the transmission gear 21 to reverse. After the transmission gear 21 reverses, it can drive the first rack 22 and the second rack 23 to move in the opposite direction. When the first rack 22 and the second rack 23 move in the opposite direction, it can drive the first slider 4 and the second slider 5 to move in the opposite direction, and then drive the first pad 6 and the second pad 7 to move in the opposite direction, and finally drive the first clamping plate 62 and the second clamping plate 72 to move in the opposite direction, until the first clamping plate 62 and the second clamping plate 72 move in the opposite direction to 1.5cm is enough, at this time, it is convenient for the upper bronchoscope to pass between the first splint 62 and the second splint 72, which is convenient for subsequent operations; when the object to be tested is a teenager, switch to the third gear setting program, control the stepper motor 2 to rotate forward, at this time, the first rack 22 and the second rack 23 can be driven to move relative to each other, and when the first rack 22 and the second rack 23 move relative to each other, the first slider 4 and the second slider 5 can be driven to move relative to each other, and then the first pad 6 and the second pad 7 can be driven to move relative to each other, and finally the first splint 62 and the second splint 72 can be driven to move relative to each other, when the first splint 62 and the second splint 72 are in contact, the first electromagnet 63 and the second electromagnet 73 are attracted to each other, and when the upper bronchoscope is against the first electromagnet 63 and the second electromagnet 73, the first electromagnet 63 and the second electromagnet 73 causes compression, at this time, the first sensor 61 and the second sensor 71 can receive the corresponding pressure value, when the pressure value reaches the specific value for teenagers on the microcontroller, at this time, the microcontroller controls the stepper motor 2 to reverse, and then can drive the transmission gear 21 to reverse, and after the transmission gear 21 reverses, it can drive the first rack 22 and the second rack 23 to move in the opposite direction, and when the first rack 22 and the second rack 23 move in the opposite direction, it can drive the first slider 4 and the second slider 5 to move in the opposite direction, and then drive the first pad 6 and the second pad 7 to move in the opposite direction, and finally drive the first clamp 62 and the second clamp 72 to move in the opposite direction, until the first clamp 62 and the second clamp 72 move in the opposite direction to 2cm, at this time, it is convenient for the upper bronchoscope to pass between the first clamp 62 and the second clamp 72, which is convenient for subsequent operations. .
