Laryngoscope

Abstract

The invention relates to the field of medical equipment and discloses a laryngoscope; the laryngoscope comprises a lens rod, a camera device connected to one end of the lens rod for photographing, a lens handle connected to the lens rod at the other end; the lens rod comprising the lens rod body, a head of the lens rod connected to the lens body; the lens rod body is rigid and holds a preset angleof arc bending, the head of the lens rod is elastic; the laryngoscope also comprises a adjusting device for adjusting the bending angle of the head tip of the lens rod; the operator in the process ofendotracheal intubation shows different angles images of the throat by adjusting the direction of the head of the lens rod; moreover, as the elastic part in the head of the lens rod is relatively soft, the head of the lens rod undergoes moderate elastic deformation when the head of the lens rod is obstructed in the process of penetrating into the human body, greatly reducing the damage of the head of the lens rod to the mucosal tissue of the throat; the rigid structure of the lens rod body is easy to adjust the direction of the tip of the laryngoscope and to guide the intubation.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a laryngoscope. Background technique [0002] Tracheal intubation is one of the important techniques to ensure effective ventilation and gas exchange in the lungs of patients, and is an important part of clinical anesthesia, emergency resuscitation and intensive care. Due to factors such as the experience of the operator, the abnormal structure of the patient's airway, and the lack of suitable tracheal intubation tools, difficult tracheal intubation occurs from time to time, often endangering the safety of the patient's life. [0003] In the prior art, although a variety of video laryngoscopes are used clinically, there is currently no tool that can solve all difficult tracheal intubation problems. Flexible fiberoptic bronchoscopes and rigid fiberoptic scopes are considered the most commonly used visualization tools for difficult endotracheal intubation. But there are still s...

AI Technical Summary

Problems solved by technology

But there are still some deficiencies in the two: the flexible fiber optic bronchoscope has problems such as complicated operation and long training and learning period, which limit its wide application

Due to the rigid mirror shaft and fixed mirror body angle, the fiber optic rigid mirror is easy to cause direct damage to the patient's upper respiratory tract and teeth during use
