Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.

Examples

The tracheal intubation is a basic operation in clinical application, is popularized in various operations and anesthesia operations, and solves the defects and problems in respiratory tract by using a catheter, when the tracheal intubation is used, the tracheal intubation needs to be guided to be inserted through an auxiliary tracheal tube, the glottis can be always seen, but cannot be smoothly inserted, and referring to fig. 2, because the tip of the tracheal intubation and the glottis have a certain distance, the tip and the glottis cannot be well tried, frequent attempts are required, therefore, referring to fig. 1, the tracheal intubation auxiliary guide core is designed, the tracheal intubation auxiliary guide core comprises an intubation guide tube shell 1 and an intubation tube 2, the intubation guide tube shell 1 and the intubation tube 2 are two parts of a traditional intubation, an air supply system is externally connected with the intubation tube 2, and the intubation guide tube shell 1 is used for assisting the intubation 2 to be inserted into a patient.

For guiding the end of the cannula 2, a fixing ring 3 is sleeved on the cannula 2, the fixing ring 3 is arranged at a position close to the end of the cannula 2, at least 1-2cm is reserved, for mutual fixation between the fixing ring 3 and the cannula 2, a first inlay 4 and a second inlay 5 are arranged in the fixing ring 3, the first inlay 4 and the second inlay 5 are arranged at a position inserted between the fixing ring 3 and the cannula 2, wherein the second inlay 5 is fixed, fixedly connected with the inner wall of the fixing ring 3 and is abutted against the outer wall of the cannula 2, the first inlay 4 is movable, and the cannula 2 needs to be clamped and fixed by the first inlay 4 and the second inlay 5 in advance before insertion, so that the fixing position of the fixing ring 3 is maintained.

Referring to fig. 4, in order to make the movable first inlay 4 have a better moving posture and degree, the first inlay 4 is in a spindle shape, and is matched with the second inlay 5 to be in contact with the outer wall of the cannula 2, and acts on the second inlay 5 in the same way, and is used for withdrawing the fixing ring 3 after the cannula 2 is aligned, specifically: the outer wall of the fixed ring 3 is provided with a threaded through hole, the threaded through hole is internally connected with a knob 10 in a threaded manner, and the knob 10 is propped against the first inlay 4, so that the screwing degree of the knob 10 is controlled, the propping force between the first inlay 4 and the cannula 2 can be controlled, and the deeper the knob 10 is, the greater the propping force between the first inlay 4 and the cannula 2 is, and vice versa;

the control mode is as follows: be equipped with a plurality of perforation 6 on solid fixed ring 3, perforation 6 and screw thread perforation are not mutually interfered, the top port department fixedly connected with spring 11 of perforation 6, the end fixed connection of spring 11 and control rod 7, connecting wire 9 runs through spring 11 central part setting, all insert in the perforation 6 and be equipped with control rod 7, spring 11's effect lies in reset control rod 7, no matter what position control rod 7 is, spring 11 all can reset control rod 7 to initial condition, so long-term use, control rod 7 is the rubber material, because control rod 7 is the rubber material so its two characteristics of taking into account deformation and rigidity, guiding ring 8 of application control lower extreme that can be fine.

Referring to fig. 3, the ends of the control rods 7 are exposed from one end of the through hole 6, and are fixedly connected with a guide ring 8, the guide ring 8 is used for driving the insertion tube 2, so the guide ring 8 needs to be sleeved on the insertion tube 2 in advance, the inner diameter of the guide ring 8 is slightly larger than that of the insertion tube 2, so the smooth degree in withdrawal is convenient, the control rods 7 and the first inlay 4 are fixedly connected with connecting wires 9, the connecting wires 9 penetrate through the insertion tube shell 1 and extend to the outer side, the ends of the connecting wires 9 are fixedly connected with pull rings 12, the connecting wires 9 control different control rods 7 by utilizing the cooperation of the pull rings 12 and fingers of hands, the position and the direction of the guide ring 8 are changed by receiving the action of force, the tip movement direction of the insertion tube 2 is controlled, after the alignment, the first inlay 4 is pulled out of the fixing ring 3 through the other connecting wires 9, the fixing rings 3 and the insertion tube 2 are not mutually extruded, and the fixing rings 3 are integrally pulled out through the other connecting wires 9, so the purpose of accommodating the insertion tube is completed, and the insertion tube is used for next time.

The foregoing is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art, who is within the scope of the present utility model, should make equivalent substitutions or modifications according to the technical scheme of the present utility model and the inventive concept thereof, and should be covered by the scope of the present utility model.
