Description

Technical Field

[0001] This invention relates to the field of medical supplies technology, specifically to a visual tracheostomy cannula insertion endoscope. Background Technology

[0002] Tracheotomy is an emergency surgery primarily used to resolve upper airway obstruction. Safe insertion of the tracheostomy tube is a crucial step during the procedure.

[0003] Prior to this invention, the conventional method of inserting a tracheostomy cannula involved direct visualization, which presented numerous inconveniences and safety hazards.

[0004] (1) Direct visualization is required for tracheostomy tube placement, but good exposure and field of vision are unlikely to be achieved in cases of obesity, short neck, goiter, or tissue edema.

[0005] (2) Direct visualization during tracheostomy cannulation: During the insertion of the tracheostomy cannula, it is difficult to clearly see the situation in front of the tracheostomy cannula, and it is impossible to effectively avoid the following situations, such as: insertion into the blind path, damage to the tracheal wall caused by incorrect insertion direction, and tracheoesophageal fistula caused by incorrect insertion direction.

[0006] (3) When a tracheostomy tube is inserted under direct vision, it is impossible to understand the condition inside the trachea, such as tracheal stenosis or tracheal neoplasms.

[0007] (4) Direct visualization during tracheostomy cannot provide information on the relative position of the tracheostomy cannot and can not be precisely adjusted. This cannot effectively prevent the tracheostomy cannot opening from pressing against the tracheal wall or causing tracheal carina.

[0008] Therefore, how to overcome the shortcomings of the existing technology is the subject of this invention. Summary of the Invention
