specific Embodiment 1

[0024] Such as Figure 4-6 As shown, the lifting adjustment device is a manual lifting adjustment device, and the manual lifting adjustment device includes a rotating rod 50 and a positioning slot bar 51 . The positioning slot bar 51 is arranged on the back of the mirror body 2 , and the positioning slot bar 51 is perpendicular to the bracket axis 12 . Specifically, the two ends of the positioning slot bar 51 are provided with one-way positioning slots from the outside to the inside, and the middle part of the positioning slot bar 51 is provided with a slide-out slot 510 .

[0025] During work, first the rotating rod 50 is placed between the mirror body 2 and the base, and one end of the rotating rod 50 is 0° parallel to the horizontal plane. The two positioning slots are slowly moved into the slide-out slot 510 in the middle, so that the mirror body 2 can be lifted and deployed. It should be noted that the rotating rod 50 can only be slid out from the sliding slot 510 .

specific Embodiment 2

[0026] Such as Figure 7-8 As shown, the lifting adjustment device is an automatic lifting adjustment device, and the automatic lifting adjustment device includes an automatic telescopic lifting rod 71 driven by a micro motor. The mirror body is provided with a positioning groove 70, and one end of the automatic telescopic lifting rod 70 is connected with the positioning groove 70. It is very convenient to control the expansion or retraction of the mirror body 2 through the extension or contraction of the automatic telescopic elevating rod 70 .

Abstract

The invention discloses a glottis lower side reflector apparatus, which comprises a base and a reflector body, wherein one side of the reflector body is arranged on the base and the other side can rotate up and down relative to the base. In comparison with the prior art, the glottis lower side reflector apparatus provided by the invention, on the basis of a light reflection principle, enables a doctor to observe tissue structures on the lower side of the glottis of a patient in an operation and to clearly see a structure of pathological change, so that the reflector apparatus is beneficial for improving the operation result of the doctor and protecting the unique and fine tissue structure in the glottis.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a subglottic mirror device. Background technique [0002] The vocal cords are left-right symmetrical membranous anatomical structures located in the larynx, and their main function is to produce sound through vibration. Clinically, new organisms in the vocal cords, such as nodules, polyps, cysts, papillomas, and cancers, can affect the vibration and closure of the vocal cords, thereby affecting vocalization, and often require surgical treatment. For the treatment of vocal cords, currently a supporting laryngoscope is generally used to extend into the oral cavity, pressurize the laryngoscope and the epiglottis, so that the doctor can see the vocal cords clearly. Since the vocal cords are not a simple "membrane" structure, but a three-dimensional structure like a "ridge", its inner edge is curved and has a unique layered organizational structure from the inside to the outside. Th...
