Trachea puncture cannula for cervical surgery

Abstract

The invention discloses a trachea puncture cannula for cervical surgery. The trachea puncture cannula for cervical surgery comprises a plastic outer tube, an air bag, an inflation port, an air source interface, an airflow detection device, a conduit, a conduit inlet device, a puncture needle and the like, wherein the conduit inlet device is an automatic rebounding and sealing device, and the conduit inlet device is automatically sealed to prevent air leakage after the puncture needle is pulled out. The trachea puncture cannula provides oxygen for patients when applied to neck surgery on vocal cords, and is inserted into the trachea through the cricothyroid membrane of the neck, the problem that in actual surgery, a trachea cannula blocks surgical spots like the laryngopharynx to increase surgical difficulty is solved, injuries of the trachea cannula to nasopharyngeal tissue of a patient are reduced, the patient can suffer from less pain, surgical difficulty is reduced for doctors, the surgical process is accelerated, and the effect is good in laryngeal surgery and cervical surgery. The air source interface is provided with a plurality of structures to realize air source access under different conditions, such as an anaesthesia machine, a breathing machine, a center air source and an air bottle type standby air source.

Description

technical field [0001] The invention relates to a tracheal intubation tube for surgery, in particular to a trachea puncture tube for surgery through the neck. Background technique [0002] Endotracheal intubation is the technique of inserting a special endotracheal tube into the trachea through the glottis. This technique can provide the best conditions for airway patency, ventilation and oxygen supply, respiratory tract suction and prevention of aspiration. Now emergency tracheal intubation Tube technology has also become an important measure in the process of cardiopulmonary resuscitation and rescue of critically ill patients with respiratory dysfunction. However, when the patient has acute laryngeal inflammation, severe laryngeal edema, giant aneurysm, etc., intubation should not be performed through the mouth. If there are nasal polyps, nasopharyngeal hemangioma, etc., nasotracheal intubation should not be performed. [0003] Neck surgery requires tracheal intubation. C...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a tracheal puncture tube for surgery through the neck. The problem of difficult surgery caused by occlusion and the large trauma area caused by cutting the trachea can be improved. It can also solve the problem that the single air source interface affects the popularization and use and the problem of the trachea sealing after the cricothyroid puncture device is withdrawn.
