Detailed Description

The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings so that the objects, features and advantages of the invention can be more clearly understood. It should be understood that the embodiments shown in the drawings are not intended to limit the scope of the present invention, but are merely intended to illustrate the spirit of the technical solution of the present invention.

As shown in fig. 1, the apparatus for performing endotracheal intubation mainly comprises a flexible advancing/retracting end 10, a flexible control motor 20, an advancing/retracting control motor 30, an axial rotation motor 40, a catheter grasping and pushing device 50, a fixing and translating module 60 and an equipment end host (not shown).

As shown in fig. 5a and 5b, the retractable end 10 is a bendable elongated tubular structure having a hollow channel 103 therein. As shown in fig. 1, a camera 101 is disposed at the front end of the flexible retractable end and can transmit video signals to the device host in real time. The inner hollow channel which can be bent, stretched, retracted and placed into the opening at the rear end of the end is continued, and can be connected with an oxygen pipeline, an injector, a suction device or an implanted fetching clamp and the like.

In order to realize the bending of the front end of the flexible advancing and retreating built-in end and facilitate the front end to advance along the bend of the trachea, the flexible advancing and retreating built-in end is of a flexible structure, for example, the flexible structure can be realized, and the flexible advancing and retreating built-in end can also be realized through a link type structural design.

According to an embodiment of the present invention, as shown in fig. 2a, two sides of the flexible advancing/retreating end 10 are a bending side surface 104 and an extending side surface 105, the bending side surface 104 and the extending side surface 105 of the flexible advancing/retreating end 10 are respectively provided with a flexible wire 106, each flexible wire is connected to the bending/extending control motor 20 at the rear end of the flexible advancing/retreating end, and the other end of each flexible wire is fixed to the front end of the flexible advancing/retreating end, so that when the rear end of each flexible wire is tensioned, the front end is correspondingly driven to move, and bending deformation is generated. According to the stress condition of the flexible wires at two sides, the front ends of the bendable and extensible insertion ends can generate different corresponding deformations.

Of course, the terms "flexible" and "flexible" are used in this specification in a relative sense, and each side may be curved, and the terms "flexible" and "flexible" are used for the sake of name differentiation.

It should be noted that, in the drawings, only one of the structural diagrams is shown to show that the retractable insertion end can be bent, and that the retractable insertion end can be actually changed in any shape as needed.

In order to further facilitate the front end of the flexible retractable entry end to deform, according to an embodiment of the present invention, a section of flexible region 102 is disposed at the front end of the flexible retractable entry end, and when the flexible wire at the flexible side of the flexible retractable entry end is pulled backward by the flexible control motor, the front end of the flexible retractable entry end is bent correspondingly, so that the front end of the flexible retractable entry end is in a forward bending state. The flexible region may be implemented by a flexible material such as rubber, by a linked structure or a plurality of connected elastic ring structures, or by a combination of materials and structural design to achieve an effect of easier bending of the front end.
