Existing video laryngoscopes include a display, a handle and a laryngoscope blade. The display and handle are reusable, and the laryngoscope blade is disposable. Generally, a video laryngoscope is equipped with three types of handles: large, medium and small, and three types of laryngoscope blades: large, medium and small, to correspond to different user groups such as adult men, adult women and children. This results in high purchase costs for hospitals. When doctors examine different patients, they will waste time choosing handles and matching laryngoscope blades, thereby reducing medical efficiency. At the same time, there will also be a problem that the handle and laryngoscope blade do not match, resulting in a waste of laryngoscope blades.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model provides Figure 1-Figure 5The laryngoscope assembly with manual controllable telescopic function shown in the figure comprises: a repetitive body 1, a connecting handle 2 is provided at the upper end of the repetitive body 1, a repetitive blade 3 is provided at the lower end of the repetitive body 1, the repetitive blade 3 is in an arc shape, and the repetitive blade 3 extends laterally toward the lower end of the repetitive body 1; the repetitive blade 3 can be used as a supporting body for connecting a disposable blade 4. The end of the repetitive blade 3 is movably connected with the disposable blade 4, and the lower end of the disposable blade 4 has a step groove 5, and the disposable blade 4 matches with the repetitive blade 3 through the step groove 5, and the disposable blade 4 is also in an arc shape, and the disposable blade 4 and the repetitive blade 3 extend in the same direction. A built-in rod 6 is provided at the position of the step groove 5 of the disposable blade 4, and a built-in channel 7 is provided in the repetitive blade 3, and the built-in rod 6 is correspondingly inserted into the built-in channel 7 of the repetitive blade 3, and the built-in rod 6 can move in the built-in channel 7. The position of the disposable blade 4 is changed by movement, so that the disposable blade 4 is extended or shortened to obtain more adaptability, which is specifically determined according to the use requirements. The repetitive blade 3 is a metal blade, and the repetitive blade 3 is fixedly connected to the lower end of the repetitive body 1 .

[0027] Considering that the repetitive body 1 is a body to be held, a plurality of grooves 13 are provided in the middle of the repetitive body 1, and the grooves 13 are all transversely arranged grooves. When in use, the plurality of grooves 4 are used to increase the holding area, and the physician can stably hold the repetitive body 1 through the plurality of grooves 4 to perform operations. The length of the disposable blade 4 is greater than the length of the repetitive blade 3. The built-in channel 7 extends from the upper end of the repetitive body 1 to the end of the repetitive blade 3, and the built-in channel 7 has a bending section 8, which is a bending portion between the lower end of the repetitive body 1 and the repetitive blade 3.

[0028] The built-in channel 7 is provided with a promotion movement unit, which includes: a manual folding spring 9, a first oil seal 10, and a second oil seal 11. The manual folding spring 9 and the first oil seal 10 are both located in the upper end of the built-in channel 7, and the manual folding spring 9 is stacked and arranged above the first oil seal 10. The second oil seal 11 is located in the lower end of the built-in channel 7, and the second oil seal 11 contacts and presses against the built-in rod 6. There is a hollow section 12 between the first oil seal 10 and the second oil seal 11, and the hollow section 12 is filled with liquid 13. In general, in order to match the structural characteristics of the utility model, the liquid 13 is used to conduct the force to overcome the linear conduction obstacle brought by the bending section 8. The liquid 13 is preferably hydraulic oil. The specific working principle is as follows. The manual folding spring 9 is an elastically deformable metal sheet. The two sides of the manual folding spring 9 are respectively provided with a limit button 14 and a lever 15. One side of the repetitive body 1 is provided with a plurality of limit holes corresponding to the position of the limit button 14, and the other side of the repetitive body 1 is provided with a rod groove corresponding to the position of the lever 15. The lowest position of the limiting hole and the rod groove is always higher than the highest liquid level of the liquid 13 in the hollow section 12, so as to avoid leakage of the liquid 13.

[0029] Working principle: first, press the limit button 14 inward, the manual folding spring 9 is compressed by the force, and the limit button 14 is separated from the limit hole. At this time, the operating lever 15 is pressed downward to drive the manual folding spring 9 and the first oil seal 10 to press down to apply pressure to the liquid 13. After the pressure is applied, the liquid 13 transmits the force to the second oil seal 11, and the second oil seal 11 contacts and presses against the built-in rod 6 to extend the disposable blade 4. The moved limit button 14 is reinserted into another limit hole under the elastic deformation of the manual folding spring 9 to achieve positioning.
