Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of medical devices, in particular to a video supporting laryngoscope suitable for difficult airway laryngeal surgery. BACKGROUND
[0002] Airway management is a crucial technique in hospital and emergency situations. Traditional laryngoscopes have some shortcomings in the operation of difficult airways. First, existing laryngoscopes are not flexible enough in operation, and the operator needs to consume relatively more power to adapt to different patient oral structures. Sometimes, the power transmission of the operation is not in place, which leads to the inability to effectively open the airway, affecting the patient's breathing.
[0003] The design of traditional laryngoscopes often cannot well protect the oral tissue. When intubation is performed, the catheter has a large contact interface with the oral cavity, which can easily cause damage or bleeding of the oral mucosa. This not only increases the patient's discomfort, but also can lead to subsequent complications, affecting the overall recovery of the patient.
[0004] The current laryngoscope is relatively single in adjustment function. Most laryngoscopes can only operate at a fixed height and cannot adjust the height according to the body type of different patients. This makes it difficult for doctors to accurately find the best operating angle in complex surgical situations, increasing the difficulty and risk of surgery.
[0005] The guide slot design of traditional devices is simple and lacks good guidance. During the catheter insertion process, it is easy to deviate from the original path or not pass smoothly. This not only wastes time, but also can cause intubation failure. SUMMARY
