[0027] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present invention, its application, or uses.

[0028] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0029] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0030] like Figure 1 As shown, the laryngoscope handle provided by the utility model comprises a handle body 1 and a pulling and matching mechanism.

[0031] The handle body 1 is provided with a traction member hole 11. The traction member 4 can pass through the traction member hole 11 and extend out of the handle body 1. The traction member 4 can pull the front end of the mirror body of the laryngoscope, so that the mirror body of the laryngoscope is bent and deformed.

[0032] The pull-fit mechanism comprises a driving member 2 and a deformable sealing member 3. The driving member 2 is rotatably connected to the handle body 1, and the rotatable connection between the two can be realized by a hinge or a ball-and-socket connection, etc. The driving member 2 can have a rod-like structure or a handle-like structure.

[0033] During specific implementation, a rotating base protruding outward may be provided on the handle body 1, and the driving member 2 is rotatably connected to the rotating base.

[0034] A sealing cavity 31 is provided in the deformable sealing member 3, and a connecting port 32 and a traction member connecting portion 33 are provided on the sealing cavity 31. The deformable sealing member 3 is a structural member that can be deformed (e.g., stretched or bent) by force, and is a columnar structure or a conical structure made of materials such as fluororubber, rubber or silicone, or can be a bellows structure.

[0035] The connection port 32 is sealed and connected to the handle body 1, and the connection port 32 is arranged corresponding to the traction member hole 11. The connection port 32 can be sealed and connected to the handle body 1 by gluing or plastic welding. When the connection port 32 is sealed and connected to the handle body 1, the traction member hole 11 will be connected to the sealed cavity 31, so that the traction member hole 11 is isolated from the outside.

[0036] The traction member connection part 33 is used to cooperate with the traction member 4 of the laryngoscope. The traction member connection part 33 can be a fixed structure located on the inner wall of the sealing cavity 31, and the fixed structure can be a fixed ring, a fixed hook or a welding point arranged on the inner wall of the sealing cavity 31. The traction member connection part 33 can also be a hole-shaped structure located on the top of the deformable sealing member 3, and the traction member 4 can pass through the hole-shaped structure and connect with the driving member 2. In order to maintain the sealing of the sealing cavity 31, the hole-shaped structure seals around the traction member 4.

[0037] The driving member 2 is connected to the deformable sealing member 3 so as to pull the deformable sealing member 3 when the driving member 2 rotates relative to the handle body 1. Under the pulling action of the driving member 2, the deformable sealing member 3 is deformed, thereby driving the traction member 4 to move, thereby pulling the front end of the mirror body of the laryngoscope, so that the mirror body of the laryngoscope is bent and deformed.

[0038] The laryngoscope handle provided by the utility model has a simple structure. The traction member hole on the handle body 1 of the laryngoscope is sealed by a deformable sealing member 3, so that the traction member 4 of the laryngoscope is in a sealed state during the use of the laryngoscope, which is convenient for disinfection of the laryngoscope handle.

[0039] In one embodiment of the laryngoscope handle of the present utility model, the driving member 2 has a rod-shaped structure. The rod-shaped driving member 2 has a simple structure, low cost, and is easy to operate.

[0040] In one embodiment of the laryngoscope handle of the utility model, a driver seat 12 is provided on the handle body 1, and the driver 2 is rotatably connected to the driver seat 12. The driver seat 12 can be hinged or ball-and-socket connected to the driver 2. The provision of the driver seat 12 facilitates more convenient operation of the driver 2.

[0041] In one embodiment of the laryngoscope handle of the utility model, in order to effectively ensure the deformation flexibility of the deformable sealing component, the deformable sealing component 3 is a bellows.

[0042] In one embodiment of the laryngoscope handle of the present utility model, the traction member connection portion 33 is a traction member through hole provided on the sealing cavity 31, and the traction member through hole is used for the traction member 4 of the laryngoscope to pass through, so that the traction member 4 of the laryngoscope is connected to the driving member 2, and the traction member through hole is sealed and connected to the traction member 4 of the laryngoscope. After the traction member 4 passes through the traction member through hole, it is connected to the driving member 2 located outside the deformable sealing member 3 (that is, the driving member 2 is connected to the deformable sealing member 3 through the traction member 4), so that the driving member 2 can directly pull the traction member 4. The sealing connection between the traction member through hole and the traction member 4 ensures the sealing of the sealing cavity 31.

[0043] In one embodiment of the laryngoscope handle of the utility model, in order to more conveniently realize the connection of various components, a drive member connection portion (not shown in the figure) is provided on the deformable sealing member 3, and the driving member 2 is connected to the driving member connection portion. The driving member connection portion is correspondingly arranged to the traction member connection portion 33. In this way, the driving member 2 is connected to the driving member connection portion, and the traction member 4 is connected to the traction member connection portion 33. The driving member 2 pulls the deformable sealing member 3, drives the traction member 4 to move, and then pulls the front end of the mirror body of the laryngoscope, so that the mirror body of the laryngoscope is bent and deformed.

[0044] During specific implementation, the driving member connection portion may be located on the outer wall of the deformable sealing member 3 , and the traction member connection portion may be located on the inner wall of the deformable sealing member 3 .

[0045] Furthermore, the driving member connecting portion and / or the traction member connecting portion 33 has a ring structure or a hook structure.

[0046] In one embodiment of the laryngoscope handle of the utility model, a connection seat surrounding the traction member hole 11 is provided on the handle body 1, and the connection port 32 is connected to the connection seat. The connection seat is provided in a more suitable manner to achieve a sealed connection between the connection port 32 and the handle body 1. The connection seat can be, for example, an annular protrusion provided on the outer surface of the handle body 1.

[0047] The utility model further provides a laryngoscope, which comprises a traction member 4 and a laryngoscope handle of the utility model, wherein the traction member 4 is connected to the driving member 2 .

[0048] In one embodiment of the laryngoscope of the present utility model, the traction member 4 is a pull rope.

[0049] In one embodiment of the laryngoscope of the utility model, it also includes a mirror body, and a pulling channel is provided in the mirror body for the pulling member 4 to pass through. The pulling member 4 is connected to the front end of the mirror body through the pulling channel, so as to achieve the purpose of pulling and bending the mirror body.
