The contraction of the airway muscles will increase the resistance to the advancement of the bronchoscope. Especially when dealing with the distal small airways, it may not be able to reach the target position, and there is a lack of a fixing device for the bronchoscope. After the bronchoscope reaches the lesion area, the doctor needs to hold the bronchoscope all the time, resulting in soreness in the doctor's hand and affecting the next step of the bronchoscope entry operation.

The output end of the electric push rod 74 is fixed with an abutting block 75. Arc-shaped grooves are formed inside both the limiting block 72 and the abutting block 75.

[0051] During use, when the front end of the lens body 2 stimulates the tracheal wall of the patient, the light of the illuminating lamp at the front end of the lens body 2 is blocked, causing the photoelectric sensor 70 to receive a signal. The photoelectric sensor 70 transmits the signal to the controller 71. The controller 71 controls the electric push rod 74 to start. The electric push rod 74 extends to push the abutting block 75. The abutting block 75 abuts against the lens body 2. The abutting block 75 and the limiting block 72 clamp the lens body 2, preventing the doctor from continuing to insert the lens body 2 into the patient's trachea. When the doctor feels the resistance, the doctor can timely adjust the position of the front end of the lens body 2. After adjusting the front end of the lens body 2, when the photoelectric sensor 70 detects the light again, the electric push rod 74 contracts, and the clamping of the lens body 2 by the abutting block 75 and the limiting block 72 is released.

[0052] In use, the position of the clamping assembly 3 is adjusted by rotating the assembly 4. Then, the fixing assembly 6, the telescopic assembly 5, and the buffering assembly 7 are stably fixed by the clamping assembly 3. Next, the bronchoscope main body 1 is placed on the fixing assembly 6, and the lens body 2 passes through the fixing assembly 6 and the buffering assembly 7. Then, the height of the fixing assembly 6 and the bronchoscope main body 1 is adjusted by the telescopic assembly 5. The bronchoscope main body 1 can rotate on the fixing assembly 6 to adjust the angle of the bronchoscope main body 1. When the lens body 2 enters the patient's trachea, disinfection treatment can be carried out. When the front end of the lens body 2 stimulates the tracheal wall of the patient, the buffering assembly 7 can slow down the speed at which the lens body 2 enters the patient's trachea and prompt the doctor to adjust the position of the front end of the lens body 2.

[0053] Embodiment 2

[0054] In the second embodiment, other structures remain unchanged. Different from the first embodiment, the outer side of the bronchoscope main body 1 is clamped inside the fixing frame 64, so that the bronchoscope main body 1 can be stably fixed. The outer side of the lens body 2 slides inside the disinfection sponge 69, so that the lens body 2 can be disinfected before entering the patient's trachea, reducing the risk of infection. The outer side of the clamping block 33 slides inside the installation groove 31, so that the clamping block 33 slides stably. The outer side of the lead screw 44 penetrates through the installation shell 40 and is threadedly connected inside the rotating ball 41, so that the lead screw 44 can limit the rotating ball 41 to prevent the rotating ball 41 from accidentally rotating. The outer circumference of the connecting rod 42 slides inside the installation shell 40, so that the connecting rod 42 can adjust the angular position of the clamping assembly 3. The inside of the installation rod 53 slides on the outer circumference of the support rod 52, so that the installation rod 53 slides stably. One end of the spring 55 is fixed to the inner wall of the installation rod 53, and the other end of the spring 55 is fixed to the outer side of the clamping block 56, so that the spring 55 can be compressed by the clamping block 56 to generate an elastic force. The clamping block 56 is clamped inside the clamping hole 51, so that the installation rod 53 slides stably. The outer circumference of the clamping block 56 slides inside the installation rod 53, so that the clamping block 56 can freely expand and contract. Arc-shaped grooves are formed inside both the limiting block 72 and the abutting block 75 for guiding and decelerating the lens body 2.
