Special tracheal catheter for occlusive bronchial cannula

Abstract

The invention provides a special tracheal catheter for an occlusive bronchial cannula used for occlusion outside a bronchus. The special tracheal catheter comprises a catheter main tube and an inflated air bag, wherein a first clamping groove is concavely formed in an outer wall surface of the catheter main tube toward an inner wall surface of the catheter main tube; and the first clamping grooveis distributed along the length direction of the catheter main tube and is arranged at a naturally bent side of the catheter main tube. According to the special tracheal catheter for the occlusive bronchial cannula provided by the invention, removable, clamped and slidable connection with an occlusive catheter of the occlusive bronchial cannula can be achieved, and the relatively fixed and movablestate can be achieved. Particularly, in a surgery, since the occlusive catheter is fixed on the special tracheal catheter for the occlusive bronchial cannula, so that the insertion of the occlusive catheter and the tracheal catheter in a bronchus occlusion process in a thoracic surgery can be completed in one step, and the use steps are simple. Due to the relatively fixed and movable design, thespecial tracheal catheter is more convenient and simpler to adjust or exit in the surgery, and the intraoperative or postoperative safety hazards can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a special endotracheal tube for blocking bronchial intubation. Background technique [0002] At present, double-lumen bronchial intubation or occluded bronchial intubation is often used in clinical thoracic surgery to collapse the lung tissue on the surgical side and achieve the effect of one-lung ventilation. In clinical work, it has been found that the use of the occluded endotracheal intubation method is more direct, and the occlusion can be observed visually with a bronchoscope at any time and suctioned according to the requirements of the thoracic surgeon, and it is convenient for the thoracic surgeon to cut off the bronchi. It is good advice to observe whether the adjacent bronchi are narrowed or to cut off the bronchi to avoid narrowing of the adjacent bronchi. [0003] The steps of the existing extratracheal method using the blocked bronchial tube are: (1) insert...

AI Technical Summary

Problems solved by technology

This kind of operation steps is cumbersome, and it is prone to safety hazards; and in practical applications, the time for blocking the bronchial intubation and the adjustment or withdrawal of the endotracheal tube is not consistent. This method of the prior art has caused a lot of inconvenience in the operation.
