Angle adjustable video laryngoscope

Abstract

The invention discloses an angle adjustable video laryngoscope. The angle adjustable video laryngoscope comprises a lens, a guiding locating sliding rod, a rotating shaft, a handle, a camera componentsystem, a spring, a stop block, a sliding guide pin and a button; the angle adjustable video laryngoscope is characterized in that the handle is arranged on the outermost side of the whole structure,the button is arranged on the left side of the upper portion outside the handle, the guiding locating sliding rod is arranged on the lower portion of the sliding guide pin, and the camera component system is arranged on the inner side of the lens. Accordingly, a patient is examined by controlling the handle with one hand, the simple actions of pressing the button inwards and moving outwards are performed with the index finger, and by means of the lever principle, the guiding locating sliding rod and the lens connected with the guiding locating sliding rod are driven to rotate clockwise and anticlockwise to be adjusted to the proper angles and positions to meet the requirements; in this way, the problems that due to the fact that a traditional product can only be adjusted to the proper angle through the lifting and prying actions of the a single arm, the process is tedious, and the posture is not likely to keep can be solved, and the angle adjustable video laryngoscope has the advantages that the manufacturing cost is low, firmness and durability are achieved, and all component connection is flexible.

Description

technical field [0001] The invention relates to the processing field of a video laryngoscope capable of automatic rotation during use, in particular to a video laryngoscope with an adjustable angle. Background technique [0002] Due to the deep position of the larynx and its complicated physiological structure, it cannot be directly seen. Some special inspection methods, such as laryngoscope, are needed for laryngeal examination. Indirect laryngoscope is the most commonly used method of laryngeal examination. Indirect laryngoscope is a circular flat mirror with a handle. The mirror surface intersects with the mirror handle at 120 degrees. The diameter of the mirror surface is different and will be selected according to the condition of the pharyngeal cavity of the subject. Appropriate size indirect laryngoscopy, this method has the advantages of being simple, easy to master, and less painful for patients. Its limitations include: patients with sensitive gag reflex cannot tol...

Indirect laryngoscope is the most commonly used method of laryngeal examination. Indirect laryngoscope is a circular flat mirror with a handle. The mirror surface intersects with the mirror handle at 120 degrees. The diameter of the mirror surface is different and will be selected according to the condition of the pharyngeal cavity of the subject. Appropriate size indirect laryngoscopy, this method has the advantages of being simple, easy to master, and less painful for patients. Its limitations include: patients with sensitive gag reflex cannot tolerate it; Unsatisfactory examination; it is difficult for children to observe laryngeal lesions due to the characteristics of laryngeal anatomy and development

The existing product technology requires the operator to adjust to an appropriate angle by pulling and prying the arm with one hand. The operation process is cumbersome, the comfort is poor, the posture is not easy to maintain, and there is a risk of causing oral injury to the patient. have higher requirements

In the production of video laryngoscopes, there is currently no video laryngoscope with an adjustable angle
