[0052] In the embodiment, the first direction is located in a first plane arranged vertically, and the first direction can be horizontally arranged or arranged obliquely to the horizontal direction. The second direction is parallel to the first direction, and both the first direction and the second direction are located in a second plane, and the first plane and the second plane are arranged vertically. When the handle part 101 of the bronchoscope 100 is configured to be mounted on the mirror frame 23, the axis of the handle part 101 is parallel to the second direction.

[0053] Specifically, the first driving unit 1 comprises a first driving assembly, the first output member 11 is connected with the first driving assembly, and the first driving assembly is used for driving the first output member 11 to move in the first direction. Specifically, the first driving assembly comprises a first screw rod 131, a first guide rail 132 and a first motor 133, the first screw rod 131 extends in the first direction, the first guide rail 132 is located at the bottom of the first screw rod 131 and is arranged in parallel with the first screw rod 131, a first nut is screwed on the first screw rod 131, and a first mounting hole is formed in the middle of the first output member 11, and the first nut is fixedly arranged in the first mounting hole. The first guide rail 132 is slidably provided with a first sliding block, and the bottom of the first output member 11 is connected with the first sliding block. The output shaft of the first motor 133 is coaxially connected with the first screw rod 131, and is used for driving the first screw rod 131 to rotate. When the first screw rod 131 rotates, the first output member 11 can move linearly in the first direction.

[0054] In other embodiments, the first driving assembly can also be arranged as a linear motor, the linear motor is connected with the first output member 11, and linear movement of the first output member 11 in the first direction is realized, which is not limited here.

[0055] As a preferred solution, the first driving unit 1 further comprises a first frame body 12. The first screw rod 131 and the first guide rail 132 of the first driving assembly are arranged inside the first frame body 12, the first motor 133 is fixed to one end of the first frame body 12 in the first direction, and one end of the first screw rod 131 penetrates through the corresponding side wall of the first frame body 12 and is connected with the first motor 133. The other end of the first screw rod 131 is rotatably connected with the side wall of the other end of the first frame body 12 in the first direction. The first frame body 12 improves the modular degree of the structure of the first driving unit 1, facilitates installation and carrying, and also improves the aesthetic degree. In the embodiment, the first frame body 12 is in the shape of a hollow rectangular shell. In the state of being arranged horizontally in the first direction, a waist-shaped through hole is formed in the top wall of the first frame body 12, the long axis of the waist-shaped through hole extends in the first direction, and the waist-shaped through hole is located directly above the first screw rod 131, so that the first output member 11 can extend out through the waist-shaped through hole and be connected with the second driving unit 2.

[0056] Further, the end face of the first frame body 12 away from the first motor 133 is fixedly provided with a first brake member 134, and the first brake member 134 is used for braking the first screw rod 131.

The first brake shaft 135 is arranged through the corresponding side wall of the first frame body 12, and then passes through the first brake 134. The first brake 134 can brake the first brake shaft 135, so as to brake the first lead screw 131. Since the electromagnetic brake brakes by holding the first brake shaft 135, the first brake shaft 135 is arranged, so that the first brake 134 can avoid directly pressing the first lead screw 131. When the first brake shaft 135 is deformed, only the first brake shaft 135 needs to be replaced, and the first lead screw 131 does not need to be replaced, thereby reducing the maintenance cost.

[0058] Specifically, bearings are arranged between the first end of the first lead screw 131 away from the first brake 134 and the side wall of the first frame body 12 and between the first brake shaft 135 and the side wall of the first frame body 12, thereby reducing the friction between the first lead screw 131 and the first frame body 12, reducing energy loss, further ensuring the driving stroke accuracy of the first driving unit 1, facilitating accurate insertion of the tracheal tube 200 and the bronchoscope 100 into the preset position, ensuring the tracheal tube effect and the treatment effect, and improving the practicability of the tracheal tube mechanism.

[0060] As a preferred solution, the auxiliary assembly 4 further comprises a roller driving member 45, which is capable of driving the first roller 43 or the second roller 44 to rotate. When the cannula 200 is clamped between the first roller 43 and the second roller 44, the roller driving member 45 is capable of assisting the delivery of the cannula 100, and reducing the frictional resistance that the cannula 200 receives, thereby ensuring that the cannula 200 can be inserted into the target position in the trachea, and ensuring the intubation effect. In the embodiment, the roller driving member 45 is provided as a motor, which is capable of driving the first roller 43 to rotate. When the cannula 200 is clamped between the first roller 43 and the second roller 44, the rotation axes of the first roller 43 and the second roller 44 are both arranged perpendicularly to the axial direction of the cannula 200, and one of the first roller 43 and the second roller 44 is located above the cannula 200, and the other is located below the cannula 200, which further ensures the supporting effect on the cannula 200, prevents the cannula 200 from being bent downward due to gravity, further ensures the accuracy of the advancing direction of the cannula 200, and ensures the intubation effect. Specifically, the first roller 43 is located above the cannula 200, and the second roller 44 is located above the cannula 200.

[0062] Specifically, the side wall of the first roller 43 and / or the second roller 44 is recessed with a ring groove 6 in the circumferential direction, and the cross section of the ring groove 6 is C-shaped, which is beneficial to limiting the cannula 200 between the first roller 43 and the second roller 44, and reducing the possibility of the cannula 200 from the auxiliary assembly 4, thereby ensuring the functionality of the auxiliary assembly 4, and ensuring the intubation effect. In the embodiment, the side wall of the first roller 43 and the second roller 44 is both recessed with a ring groove 6 in the circumferential direction.

[0063] Specifically, the first roller 43 and the second roller 44 are arranged on the side of the roller frame 42 facing the cannula 200, and the roller driving member 45 is connected to the side of the roller frame 42 opposite to the cannula 200.

Further specifically, the bottom of the roller frame 42 is connected to the vertically arranged support rod 421, and the bottom of the support rod 421 is connected to the steering joint 48. When the cannula 200 is mounted on the mounting frame 32 and the handle portion 101 of the bronchoscope 100 is mounted on the scope frame 23, the above structure is arranged to ensure that the first roller 43 and the second roller 44 sandwich the cannula 200, and the cannula 200 is coaxially arranged with the handle portion 101.

[0064] As a preferred solution, the auxiliary assembly 4 further comprises an adapter 46 arranged on the side of the roller frame 42 facing the cannula 200, and the first roller 43 and the second roller 44 are arranged on the adapter 46. The adapter 46 is detachably connected to the roller frame 42, so that the first roller 43 and the second roller 44 can be detached from the tracheal intubation mechanism, facilitating the complete disinfection of the tracheal intubation mechanism, preventing incomplete disinfection due to excessive size of the structure, and thereby reducing the risk of cross infection.

[0065] Further, the first roller 43 is rotationally connected to one end of the adapter 46 along the third direction, the adapter 46 is provided with an adjusting member 47, and the second roller 44 is rotationally connected to the adjusting member 47. The adjusting member 47 is capable of sliding along the third direction to move the second roller 44 closer to or farther away from the first roller 43, and the third direction is perpendicular to the rotation axes of the first roller 43 and the second roller 44. The adjusting member 47 is arranged to adjust the distance between the first roller 43 and the second roller 44, thereby expanding the diameter range of the cannula 200 applicable to the auxiliary assembly 4, expanding the application range of the tracheal intubation mechanism, and improving the practicability.

[0066] Specifically, the adapter 46 is provided with an opening on the end face of the other end of the third direction, and the adjusting piece 47 is arranged in the opening and can slide in the opening and extend out or retract into the adapter 46. The adjusting piece 47 is provided with a plurality of adjusting grooves 471, which extend along the extension axis perpendicular to the third direction and penetrate through the two side walls of the adjusting piece 47, and the adjusting grooves 471 are arranged in multiple along the third direction.

The limiting piece 49 can be arranged in the adjusting groove 471 to limit the position of the adjusting piece 47, so as to manually adjust the distance between the first roller 43 and the second roller 44, so that the first roller 43 and the second roller 44 can clamp the cannula 200 of different sizes. Further specifically, the first roller 43 is arranged on the first end face of the adapter 46, the first end face is parallel to the third direction, the opening of the adapter 46 penetrates through the first end face, the adjusting piece 47 is arranged in the opening, and the second end face of the second roller 44 arranged on the adjusting piece 47 is flush with the first end face, and the adjusting groove 471 of the adjusting piece 47 is arranged on the second end face.
