Technical Field

The utility model belongs to the technical field of the medical instrument technique and specifically relates to a visual laryngoscope of concertina type.

Background

The deep situation of the throat can be seen only by a special tool and a special detection method if the deep situation of the throat is wanted to be seen, so that the disease can be determined; the visual laryngoscope is a special laryngoscope product, also called indirect laryngoscope, generally speaking, the indirect laryngoscope is a round plane mirror with a handle, the mirror surface and the handle intersect at 120 degrees, the diameters of the mirror surface are different, and the indirect gastroscopy with proper size is selected according to the pharyngeal cavity condition of the examined person; the general laryngoscope does not have visibility, must pass through external light source, can operate after carefully observing with the naked eye, not only waste time, be difficult to succeed moreover, efficiency is extremely low, too painfully too to doctor, also be bare-hearted to increase the misery to patient.

The visual laryngoscope (SOS) is a fiber light guide shapeable laryngoscope, has the advantages of a light rod and a fiber bronchoscope, and can be used for normal tracheal intubation and various difficult tracheal intubation. The assembly is simple, the front end angle is adjustable, the intubation success rate is high, and the device plays an increasingly important role in establishing the artificial respiratory tract; generally, the glottis position is confirmed through a visual laryngoscope, and then the intubation is led into the trachea through the guide wire. But traditional visual laryngoscope utilizes the probe to survey the trachea environment, mainly observe through the little window of blade above the sleeve pipe, but have some very difficult air flues, the probe is difficult for stretching to the trachea depths, can not observe the circumstances in the trachea at will, and at present the pipe can not stretch out and draw back at will, rotate at will, so the probe just can not be accurate effectual in the interior glottis of surveying the trachea and corresponding environment, thereby can't make corresponding trachea cannula get into and treat, therefore current trachea cannula technique exists that it is not good to survey the internal environment effect, the trachea inserts inconvenient problem.

Chinese patent documents: CN207837521U, published: 2018.09.11 discloses a length-adjustable visual laryngoscope, which comprises a handle, a lens and a display, wherein the handle and the lens are connected to form a J shape, it is characterized in that the mirror handle is provided with a telescopic piece which comprises a first telescopic piece and a second telescopic piece, the outer diameter of the first telescopic part is matched with the inner diameter of the second telescopic part, the first telescopic part is sleeved with the second telescopic part, the mirror handle wall of the first telescopic part is provided with an elastic sheet, the elastic sheet is provided with a convex point, the elastic sheet and the convex point are integrally formed, a button groove is arranged on the wall of the mirror handle of the second telescopic part, a button is clamped in the button groove, a button pressing plate is fixedly connected behind the button and is positioned at the center of the button groove, a double-hole plate is arranged behind the button pressing plate and is fixedly connected with the inner wall of the mirror handle to form a cavity, the button can press the board and be slightly less than the orifice plate and be located the cavity that orifice plate and mirror handle formed.

Chinese patent documents: CN207666571U, published: 2018.07.31 discloses a visual laryngoscope, which comprises a display, a handle and a hollow laryngoscope lens, wherein the rear end of the handle is rotatably connected with the display, the front end of the handle is rotatably connected with the rear end of the laryngoscope lens, the handle is internally provided with a pair of meshed gear A and gear B, the gear B is arranged on a first rotating shaft, the outer side of the handle is provided with a knob, the knob is coaxially arranged on the first rotating shaft, the gear A is arranged on a second rotating shaft, the gear A is fixedly connected with the laryngoscope lens, the first rotating shaft is rotatably connected with the handle, and the second rotating shaft is fixedly connected with the handle.

The above patent documents: one of the CN207837521U visual laryngoscope with adjustable length has simple structure and convenient operation, can adjust the length and the angle of the lens and is suitable for different airways. Patent documents: the visible laryngoscope in CN207666571U has simple operation and convenient use, and the included angle between the laryngoscope blade and the handle can be adjusted only by rotating the knob, thereby facilitating the placement of the laryngoscope blade and being beneficial to collecting the image of the throat of a patient.
