Description

Improved double-cavity trachea cannula for thoracic operation

Technical Field

The utility model belongs to the field of medical equipment, in particular to an improved double-cavity trachea cannula for thoracic surgery.

Background

Chest surgery often requires unilung ventilation to protect the healthy lung from lung contamination and to provide a good field of view for the procedure. Double lumen tracheal intubation is currently the most commonly used method for performing single lung ventilation, with Rorbertshaw double lumen tubes being most used. However, in clinical use, the tube is found to have the defects of difficult tube placement, easy displacement in the operation, more postoperative complications and the like. The reason for the analysis is related to the tube design: the existing double-cavity trachea cannula is divided into a left tube and a right tube, wherein the left tube is used for right lung operation, and the right tube is used for left lung operation. Because the left and right side bronchus are dissected differently, the left side bronchus is longer, and is easy to fix after being placed, and the ventilation of the right lung is generally not influenced. However, the right bronchus is shorter, and the opening direction of the bronchus of the upper right lobe is changed, but the vent hole of the right tube of the right bilateral tracheal cannula clinically used at present has a smaller opening and a fixed angle, and is easy to shift after the tube is placed, so that the ventilation of the right lung of a patient is affected, as shown in fig. 1 and 2, wherein 1-the right tube of the right bilateral tracheal cannula; 2-air bag; 3-air vent.
