Equipment adjusting device for self-retaining laryngoscope operation examination

Abstract

The invention discloses an equipment adjusting device for self-retaining laryngoscope operation examination. The device comprises a sleeve rod, a vertical rod, a slot, a knob, a bottom plate, a supporting rod, a top plate, a clamping groove, a screw rod, a fixed shaft, a movable shaft, a magnet, a guide rod, a clamping rod, a movable block, a connecting rod, an adjusting plate, a connecting plate, a pawl, a sleeve plate, a rotating plate, a reset spring, a limiting rod, a push plate, a limiting block, a rod body, a groove, a connecting shaft, an end, a laryngoscope main body, a clamping plate, clamping teeth, a limiting pin, a connecting spring, a pressing plate, a wedge-shaped block, a joint, an open hole, an inspection mirror and a gear. According to the invention, the device has the beneficial effects that the height and angle of the self-retaining laryngoscope can be adjusted according to the use condition, so that the practicability of the self-retaining laryngoscope is improved, fine adjustment of the self-retaining laryngoscope can be conducted according to the complex position of the throat after adjustment, the whole self-retaining laryngoscope is stable in supporting, the safety performance is improved, multi-angle adjustment of the self-retaining laryngoscope can be conducted, the laryngoscopy efficiency is improved, the adjustment and fixation are convenient, and the supporting stability of the laryngoscope can be improved.

Description

technical field [0001] The invention relates to an equipment adjustment device for supporting laryngoscope operation inspection, in particular to an equipment adjustment device for supporting laryngoscope operation inspection, which belongs to the technical field of laryngoscope application. Background technique [0002] Laryngoscope is a device used for laryngeal examination. Due to the deep position of the larynx and its complicated physiological structure, it cannot be directly seen. Some special inspection methods are needed for laryngeal examination, such as indirect laryngoscope, direct laryngoscope, fiber laryngoscope, etc. Laryngoscope, electronic laryngoscope, stroboscopic laryngoscope, ultra-high-speed film photography, sonogram or glottic graph, the surface intersects with the mirror handle at 120 degrees, the diameter of the mirror surface is different, and the appropriate one should be selected according to the condition of the pharyngeal cavity of the subject. ...

AI Technical Summary

Problems solved by technology

Because the mirror surface is tilted downward by 45 degrees, the image of the larynx seen in the mirror and the real larynx are reversed front-to-back and left-right unchanged. Due to the limitation of the size of the indirect laryngoscope mirror, the entire larynx cannot be seen at the same time, so it should be The mirror rotates slowly, and the throat is checked area by area. This method has the advantages of simplicity, ease of grasp, and less pain for the patient. Its limitations include: patients with sensitive gag reflex cannot tolerate it; The patient's laryngeal examination is unsatisfactory; it is difficult for children to observe laryngeal lesions due to the characteristics of laryngeal anatomy and development

[0003] In the patent document "CN211155703U supporting laryngoscope", the upper part of the mirror body will naturally form a slight upturn, just to provoke the epiglottis; ensure that the glottis is completely exposed in the front mirror port; the operable space is more sufficient; apply a small The driving force achieves the effect of easily and precisely adjusting the laryngoscope, but it lacks the adjustment function, and it is inconvenient to adjust during use. The doctor needs to hold the laryngoscope to open the epiglottis, which is easy to cause accidental injury during operation, and the angle of the laryngoscope is too high. Difficult to adjust, it is difficult to effectively observe the condition of the larynx, which affects the effect of laryngoscopy

At present, there is no equipment adjustment device for supporting laryngoscope surgery inspection with reasonable and reliable structure, convenient adjustment and stable operation performance.
