DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are partial embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

[0015] The retractable and shapeable intelligent laryngoscope according to a preferred embodiment of the present invention, as Figure 1 shown, also refer to Figure 2 and Figure 3, including a connected handle 1 and a lens, the lens is composed of a plurality of sub-units 2 connected in sequence; the sub-unit 2 includes a bottom plate 20 (preferably, 3-6 can be set), side plates 21 are arranged on both sides of the bottom plate 20, and the adjacent side plates 21 of two adjacent bottom plates 20 are connected by an elastic cloth 22. The frontmost bottom plate 20 is connected to the handle 1, and a tongue pressing part 23 is formed on the rearmost bottom plate 20; a locking tongue 24 for adjustment is arranged at the front end of the upper surface of the bottom plate 20; a connecting elastic piece 25 is rotatably arranged on the upper surface of the bottom plate 20, and the connecting elastic piece 25 is rotatably connected to the corresponding bottom plate 20 through a rotating shaft 26. A plurality of card slots 27 are arranged along the length direction at the end of the locking tongue 24. The connecting elastic piece 25 elastically presses the locking tongue 24, and a clamping convex block 28 matched with the card slot 27 is arranged on the connecting elastic piece 25. A damping piece 29 which is attached to the bottom plate 20 and provides a damping force is arranged on the bottom surface of the locking tongue 24; a reverse L-shaped locking screw 3 is threadedly connected to the connecting elastic piece 25, and an avoidance groove for avoiding the locking screw 3 is arranged at the front end of the locking tongue 24, and the avoidance groove is adapted to the locking screw 3; an installation frame for installing a camera and a lighting lamp is arranged on the side plate of the rearmost bottom plate 20.

[0016] According to the actual use requirements, determine one or more groups of bottom plate groups to be adjusted, and each group of bottom plate groups includes two adjacent bottom plates 20; rotate the locking screw 3 on the previous bottom plate counterclockwise to release the locking of the connecting elastic piece 25; rotate and adjust the angle of the connecting elastic piece 25 according to the required curvature, so as to adjust the angular position between the rear bottom plate 20 and the previous bottom plate 20. The elastic cloth 22 adaptively adjusts by relying on its own elasticity. During the adjustment process, the damping force is provided by the damping piece, and after the adjustment is in place, the damping positioning is carried out by relying on the damping piece 29; adjust the engagement relationship between the card slot 27 of the locking tongue 24 on the rear bottom plate and the clamping convex block 28 of the connecting elastic piece 25 on the previous bottom plate 20 according to the required spacing, so as to adjust the overall length between the rear bottom plate 20 and the previous bottom plate 20; after the adjustment is completed, rotate the locking screw 3 clockwise for fixation; The intelligent laryngoscope applying the present application can not only realize the curvature adjustment but also realize the length adjustment. Moreover, the curvature adjustment in both adjustments adopts a stepless adjustment method, the adjustment operation is convenient, and the overall mechanical strength can still be guaranteed after the adjustment, solving the industry problem; In addition, it should be noted that the adjustment structure makes clever use of the damping sheet 29 to provide damping. While the damping sheet 29 is used to provide damping for rotational adjustment, it also cooperates with the connecting elastic sheet 25 to complete the elastic clamping of the lock tongue, which can effectively reduce the looseness caused by machining gaps. Further, the card slot 27 is in an eight-shaped configuration, and the avoidance slot is located in the middle of the eight-shaped card slot 27. Using the card slot 27 with this shape structure can effectively ensure the stability after clamping and prevent left-right shaking. During application, the elastic part of the connecting elastic sheet 25 is preferably made of a stainless steel sheet with a thickness of about 1 mm to ensure its elasticity while ensuring a relatively large connection strength, and the insertion stroke of the lock tongue is not less than half of its own length.

[0017] Preferably, the connecting elastic sheet 25 includes a rigid fixing sheet 250 and a metal elastic sheet 251. The rear end of the rigid fixing sheet 250 is connected to the metal elastic sheet 251 (a stainless steel sheet with a thickness of about 1 mm is selected). A clamping convex block 28 is provided on the metal elastic sheet 251. A screw hole 2501 for cooperating with the locking screw 3 is provided on the rigid fixing sheet 250. The front end of the rigid fixing sheet 250 is rotatably connected to the bottom plate 20 through a rotating shaft 26. A convex arc surface is provided on the upper surface of the metal elastic sheet 251, and a positioning groove 2510 for positioning the locking screw 3 in the locked state is provided on the arc surface. A protective fork 2500 for blocking the gap between it and the bottom plate is provided at the front end of the rigid fixing sheet 250. The design of the positioning groove 2510 can effectively prevent the accidental loosening of the locking screw 3 in the locked state and ensure the reliability of locking. It should be noted that if the locking screw 3 has not entered the locked state when it enters the positioning groove 2510, it indicates that there are defects in the machining accuracy of the locking screw 3 or wear after long-term use, and corresponding replacement treatment is required. Through the cooperation of the locking screw 3 and the positioning groove 2510, the upward rebound amplitude of the metal elastic sheet 251 is also limited, and the strength of the metal elastic sheet 251 is further improved. The setting of the protective fork 2500, while positioning the rotating shaft 26 (the fork groove size is equivalent to that of the rotating shaft), blocks the gaps on both sides of the rotating shaft 26 to prevent insertion into the gap during intubation and cause interference to intubation.

Rotate and adjust the angle of the connecting elastic sheet according to the required bending degree, thereby adjusting the angular position between the rear bottom plate and the previous bottom plate, and the elastic cloth adaptively adjusts relying on its own elasticity. Adjust the engagement relationship between the card slot of the lock tongue on the rear base plate and the engaging protrusion of the connecting elastic piece on the front base plate according to the required spacing, thereby adjusting the overall length between the rear base plate and the front base plate; After the adjustment is completed, rotate the locking screw clockwise to fix it; Applying the method of the present application can not only achieve arc adjustment but also achieve length adjustment. Moreover, the arc adjustment in both adjustments adopts a stepless adjustment method, which is convenient for adjustment operation. After adjustment, the overall can still ensure high mechanical strength, solving the problems in this industry.
