[0028] In order to more clearly illustrate the above-mentioned purposes, features and advantages of the present application, the following will further describe the scheme of the present application. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0029] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present application, not all the embodiments.

[0030] The fibrobronchoscope auxiliary intubation visual laryngoscope blade of the utility model is described below in combination with the drawings.

[0031] As Figure 1 , Figure 2 and Figure 3 indicated, the fibrobronchoscope auxiliary intubation visual laryngoscope blade of the utility model embodiment can include a blade body 1 and a guide tube 2, wherein the blade body 1 is a visual laryngoscope blade body.

[0032] The guide tube 2 is detachably connected to the blade body 1, and a guide channel 3 with openings at both ends and a closed periphery is formed between the guide tube 2 and the blade body 1, for assisting in guiding the fibrobronchoscope 4.

[0033] As a possible case, in order to minimize the damage that the guide tube 2 can cause to human tissues during insertion, all edges or corners of the guide tube 2 can be rounded (not shown in the drawings). This processing not only makes the profile of the guide tube 2 smoother and more fluent, reducing friction and pressure with the surrounding tissues, but also significantly improves the comfort of the patient and reduces the risk of complications caused by improper operation.

[0034] The guide tube 2 and the blade body 1 can be selected as a disposable matched product, that is, the guide tube 2 is pre-installed on the blade body 1, and the whole is disposable, to ensure the sterile effect during use. Another solution is that the guide tube 2 and the blade body 1 are designed separately, the blade body 1 is discarded after being used as disposable consumables, and the guide tube 2 can be reused through a sterilization program, thereby reducing the cost of medical consumables.

[0035] Specifically, in the actual operation, first, the blade body 1 is installed on the laryngoscope handle, then the blade body 1 is gently inserted into the patient's throat, and then the fibrobronchoscope 4 is inserted into the guide channel 3. At this time, the guide channel 3 not only provides a clear guide for the advancement of the fibrobronchoscope 4, but also plays a supporting role. With the assistance of the visual laryngoscope, once the epiglottis is seen, by adjusting the inclination angle of the front end of the fibrobronchoscope 4, the lens of the fibrobronchoscope 4 can be accurately aligned with the glottis and smoothly enter the glottis. Then, the blade body 1 is slowly withdrawn, and the guide tube 2 can be detached from the blade body 1, so that the blade body 1 can be smoothly removed from the fibrobronchoscope 4. Next, the tracheal tube is pushed to the glottis along the path of the fibrobronchoscope 4, thereby completing the tracheal intubation operation.

[0036] Therefore, the guide channel 3 jointly constructed by the guide tube 2 and the blade body 1 plays a guiding and supporting role in the intervention process of the bronchoscope 4 on the patient with difficult visual laryngoscope insertion. This design not only significantly shortens the insertion time of the bronchoscope 4, reduces the operation difficulty of beginners, and enables less experienced medical staff to easily operate, but also effectively avoids the risk of throat and oral cavity wall injury caused by repeated intubation due to the deviation of the bronchoscope 4 path, solving the problem that it is difficult to control the direction and easy to deviate from the path during the insertion process of the bronchoscope 4, especially for less experienced personnel, it is difficult to accurately insert the bronchoscope 4.

[0037] Further, as shown in Figure 1 , the blade body 1 includes a tongue blocking piece 10 and a limiting tube 11 for guiding the insertion of the laryngoscope handle.

[0038] Among them, the limiting tube 11 is fixed on the tongue blocking piece 10, and an L-shaped gap 100 is formed between the limiting tube 11 and the tongue blocking piece 10, the guide tube 2 is arranged in the gap 100, and the guide tube 2 is detachably connected with the limiting tube 11, wherein the space between the tongue blocking piece 10 and the limiting tube 11, that is, the gap 100 position, makes the guide tube 2 can be compactly placed therein, avoiding additional volume occupation, while also providing a smoother path for the smooth insertion of the bronchoscope 4, and the separation design of the guide tube 2 and the blade body 1, on the one hand, by separating the guide tube 2 from the blade body 1, it is convenient to withdraw the blade body 1 from the bronchoscope 4, on the other hand, by replacing the blade body 1 while retaining the guide tube 2, the purpose of reducing the cost of consumables can be achieved.

[0039] In an embodiment of the present application, as shown in Figure 1 and Figure 4 , the blade body 1 further includes a plurality of limiting columns 12, the plurality of limiting columns 12 are respectively arranged on the limiting tube 11, the guide tube 2 is in the shape of several characters, and a plurality of through holes (not shown in the drawing) are respectively formed on the two folded edges 20 of the guide tube 2, and the plurality of through holes and the plurality of limiting columns 12 are arranged one by one, and the limiting column 12 can be arranged in the through hole to fix the guide tube 2 on the limiting tube 11.

[0040] It should be noted that the number of limiting columns 12 is not fixed, but can be flexibly configured according to actual application scenarios and specific needs. For example, the limiting column 12 can be set to 2, 3, 4 or more, which depends on the fixing requirements of the guide tube 2, the structural design of the blade body 1 and the stability requirements in the operation process.

[0041] Specifically, when installing the guide tube 2, the plurality of through holes pre-set on the guide tube 2 are accurately aligned with the limiting posts 12 on the limiting tube 11, and then the guide tube 2 is pressed towards the direction of the vane body 1. The limiting posts 12 can smoothly pass through the corresponding through holes, thereby stably fixing the guide tube 2 on the limiting tube 11.

[0042] When the guide tube 2 needs to be disassembled, the operation is also simple and fast. By forcibly pulling out the guide tube 2 away from the vane body 1, the separation of the guide tube 2 from the vane body 1 can be easily achieved. This design not only simplifies the installation and disassembly steps, but also greatly improves the convenience and efficiency of operation, so that medical staff can quickly and accurately complete the replacement or adjustment of the guide tube 2 in an emergency.

[0043] Further, as shown in Figure 4 , the limiting post 12 comprises a column 120 and a rubber head 121, the diameter of the column 120 is matched with the diameter of the through hole, which ensures that the guide tube 2 can be firmly fixed on the limiting tube 11 during installation, reducing displacement caused by shaking or external force, and the diameter of the rubber head 121 is larger than that of the through hole, when the guide tube 2 is fixed on the limiting tube 11, the rubber head 121 is attached to the folded edge 20, the rubber head 121 can be used to limit and press the folded edge 20, and the contraction of the rubber elasticity of the rubber head 121 can facilitate the rubber head 121 to pass through the through hole.

[0044] Further, as shown in Figure 4 , the rubber head 121 is narrow at the top and wide at the bottom, the design of the narrow top facilitates the rubber head 121 to be initially guided and smoothly fitted into the through hole, reducing the resistance and difficulty during installation, and improving the convenience of operation, and the design of the wide bottom can press and limit the folded edge 20.

[0045] In an embodiment of the present application, as shown in Figure 4 , the rubber head 121 is rounded 1210 near the circumference of one end of the column 120, the design of the rounded corner 1210 makes the contact surface between the rubber head 121 and the folded edge 20 smoother, reducing the frictional resistance when pulling out, so that medical staff can more easily pull out the guide tube 2 from the limiting post 12 when disassembling the guide tube 2, improving the convenience of operation, not only reducing the resistance when pulling out, but also avoiding scratching or wearing the folded edge 20 during the pulling-out process. This design helps to prolong the service life of the folded edge 20.

[0046] In an embodiment of the present application, as shown in Figure 1As shown, when the guide tube 2 is fixed on the limiting tube 11, the rubber head 121 is at least partially extruded and fitted on the side wall of the guide tube 2, increasing the contact area and friction between the two, thereby enhancing the stability of the guide tube 2 on the limiting tube 11. This design helps to prevent the guide tube 2 from being displaced or falling off due to external forces during use, ensuring the reliability and safety of the guide tube 2 after installation.

[0047] In an embodiment of the present application, as shown in Figure 1 The tongue piece 10, the limiting tube 11 and the guide tube 2 are all arc-shaped, and the arc angle trend path of the limiting tube 11 and the guide tube 2 is the same as that of the tongue piece 10, wherein the arc design can match the natural curvature of the upper airway of the human body, so that it can more gently avoid the teeth, tongue root, tonsils and tongue-palatine arch structure during insertion, avoiding compression and damage to these parts, and the arc-shaped tongue piece 10, limiting tube 11 and guide tube 2 design can expand the glossoepiglottic space, providing a larger field of view and operation space for the operator. This design can significantly improve the success rate and safety of the operation.

[0048] In an embodiment of the present application, as shown in Figure 1 And Figure 3 The diameter of the guide tube 2 is larger than the diameter of the fiber bronchoscope 4, wherein the larger diameter provides sufficient space for the fiber bronchoscope 4 to easily insert into the guide tube 2. This not only simplifies the insertion process, but also reduces the resistance caused by friction, allowing medical personnel to adjust more smoothly during operation.

[0049] In summary, the fiber bronchoscope auxiliary intubation laryngoscope blade of the present application can guide the insertion of the fiber bronchoscope, saving the time of inserting the fiber bronchoscope, facilitating the use of inexperienced personnel, and effectively avoiding the damage to the throat and the injury to the inner wall of the mouth caused by the repeated tracheal intubation due to the deviation of the fiber bronchoscope.
