[0002] Laryngoscope is a device used for laryngeal examination. Due to the deep location of the larynx and its complex physiological structure, it cannot be directly viewed. Some special examination methods are needed for laryngeal examination, such as indirect laryngoscope, direct laryngoscope, fiber laryngoscope, electronic laryngoscope, stroboscopic laryngoscope, ultra-high-speed film photography, sonogram or glottomogram. The mirror surface intersects with the mirror handle at 120 degrees, and the diameter of the mirror surface is different. The appropriate size of indirect laryngoscope should be selected according to the pharyngeal condition of the examinee. During the examination, the examinee is sitting in a chair, leaning forward, opening his mouth and sticking out his tongue. The front third of the tongue is wrapped with clean gauze, and the tongue is pulled forward and downward. The indirect laryngoscope is heated but not hot and placed in the oropharynx. The examinee is asked to take a deep breath to move the root of the tongue forward and lift the epiglottis. The mirror surface of the indirect laryngoscope is illuminated by a forehead mirror or a headlight, and the image in the mirror is observed to examine the laryngeal structure. When inserting the indirect laryngoscope, the mirror surface should be downward, and quickly and steadily placed on the soft palate at a 45-degree angle to the horizontal plane without touching the tongue, hard palate, and tonsils, so as not to cause nausea reflex and hinder the examination. If the subject has a strong pharyngeal reflex and cannot cooperate, a small amount of 1% dicaine can be sprayed on the pharynx before the examination.

[0003] After searching, the patent application number is (202020656256.9), which discloses "a supported laryngoscope". The supported laryngoscope includes a mirror tube and a support handle; the mirror tube includes a smoothly connected fixed section and a curved section, and the curved section is a bendable pipe; the side walls of the curved section and the fixed section are provided with a guide wire channel, and a traction wire is passed through the guide wire channel. One end of the traction wire is fixed to the side wall of the curved section, and the other end passes through the guide wire channel, and a traction handle is provided at the end of the passing end. The supported laryngoscope adopting this structure can effectively solve the problem that the patient's throat is easily damaged during the insertion process of the existing laryngoscope; However, the above device has the following problems: it is inconvenient to adjust during use.

[0020] Through the setting of the linkage component 4 in this device, the problem that the angle adjustment is inconvenient during laryngoscope examination, it is difficult to effectively observe the laryngeal condition, and the effect of laryngoscope examination is affected is solved.

[0021] Further, two sets of limiting components 5 are arranged inside the handle 1. The limiting component 5 includes a first movable slot 51, a ratchet wheel 52, a second rotating shaft 53, a movable plate 54, a first telescopic rod 55 and a first spring 56. A first movable slot 51 is formed at the bottom of the handle 1. Two sets of ratchet wheels 52 are fixedly connected to the outer surface of the first rotating shaft 41 on the inner wall of the handle 1. The teeth of the ratchet wheel 52 are distributed clockwise. A second rotating shaft 53 is rotatably connected inside the first movable slot 51. A movable plate 54 is fixedly connected to the inner side of the second rotating shaft 53. The movable plate 54 is L-shaped, and the right lower end is connected with teeth meshing with the ratchet wheel 52. The teeth of the movable plate 54 and the teeth of the ratchet wheel 52 face in opposite directions. First telescopic rods 55 are arranged at the left lower end and the right upper end of the ratchet wheel 52. A first spring 56 is arranged inside the first telescopic rod 55. The two ends of the first spring 56 are respectively abutted against the inner wall of the first telescopic rod 55 and the first spring 56. The bottom of the first telescopic rod 55 is fixedly connected to the inner wall of the first movable slot 51. The other end of the first telescopic rod 55 is attached to the surface of the movable plate 54. As Figure 6 shown, when the structure drives the ratchet wheel 52 to rotate clockwise through the first rotating shaft 41, the teeth of the ratchet wheel 52 push the movable plate 54. The movable plate 54 is rotatably installed inside the handle 1 through the second rotating shaft 53, so that the movable plate 54 swings. At the same time, the first telescopic rod 55 is squeezed and compressed, and the first spring 56 deforms, so that the support lens tube 3 can rotate clockwise. After adjusting to a suitable angle, under the elastic action of the first spring 56, the first telescopic rod 55 is pushed to return to its original position, so that the teeth of the movable plate 54 are inserted into the gaps of the ratchet wheel 52 to limit the ratchet wheel 52.

[0024] Furthermore, three groups of second fixing grooves 11 are provided on the left surface of the slider 62. The diameters of the three groups of second fixing grooves 11 are the same, and the second fixing grooves 11 are equidistantly distributed. As Figure 4 shown, this structure is used for the convenience of pressing the slider 62 through the setting of the second fixing grooves 11, which conforms to the finger joint part.

[0025] Furthermore, three groups of first fixing grooves 10 are provided on the left surface of the handle 1. The positions where the first fixing grooves 10 reach correspond to the second fixing grooves 11. As Figure 3 shown, this structure is used for the convenience of opening the fingers to hold the two sides of the second fixing grooves 11 of the handle 1 through the first fixing grooves 10 corresponding to the second fixing grooves 11 at the handle 1, and at the same time preventing the user from accidentally touching the slider 62.

[0026] Furthermore, an anti-slip pad 12 is fixedly connected to the outer surface of the handle 1, and the surface of the anti-slip pad 12 is provided with wavy anti-slip lines with a depth of two millimeters. As Figure 5 shown, this structure is used for the characteristics of rubber having buffering and anti-slip properties. Its anti-slip lines can improve its anti-slip effect, avoid slipping out of the palm when holding the handle 1, and the depth of two millimeters can be used to ensure that the anti-slip lines still have an anti-slip effect after a certain degree of wear.

[0027] Working principle: When in use, as Figure 1 and Figure 2As shown, the support mirror tube 3 is partially inserted into the patient's oral cavity. When inserting, the endoscope through-tube 100 is activated, and then operations on the patient's laryngeal cavity are realized. By swinging the adjustment plate 43, under the action of the first rotating shaft 41 being rotatably connected to the handle 1, the support mirror tube 3 adjusts its angle along with the swing of the adjustment plate 43. As Figure 6 shown, when the ratchet wheel 52 is driven by the first rotating shaft 41 to rotate clockwise, the teeth at the ratchet wheel 52 push the movable plate 54. The movable plate 54 is rotatably installed in the handle 1 through the second rotating shaft 53, causing the movable plate 54 to swing. At the same time, the first telescopic rod 55 is compressed under extrusion, and the first spring 56 deforms, enabling the support mirror tube 3 to rotate clockwise. After adjusting to an appropriate angle, under the elastic action of the first spring 56, the first telescopic rod 55 is pushed back to its original position, so that the teeth at the movable plate 54 are inserted into the gaps of the ratchet wheel 52 to limit the ratchet wheel 52. When the support mirror tube 3 is rotated in the opposite direction, as Figure 4 and Figure 7 shown, the finger is placed at the second fixed groove 11 to press the slider 62, causing the slider 62 to move into the interior of the second movable groove 61. At the same time, the second telescopic rod 65 is compressed and contracted under extrusion, and the second spring 66 deforms, enabling the guide groove 64 at the bottom of the slider 62 to push the connecting block 63. Through the rotatable installation of the movable plate 54, the movable plate 54 rotates, disengaging the teeth at the lower right end of the movable plate 54 from the gaps of the ratchet wheel 52, enabling the adjustment plate 43 to drive the support mirror tube 3 to rotate counterclockwise. After adjustment, the slider 62 is released, and under the restoring action of the second spring 66, the second telescopic rod 65 is pushed to restore the slider 62 to its original position, thereby realizing the adjustment of the support mirror tube 3 at any angle. The above is the entire working principle of the present invention.
