Abstract
A surgical technique, non-invasively and safely and quickly inserting a T-shaped tube into a stenotic trachea, is capable of replacing a traditional rigid bronchoscope with a harmless fiber bronchoscope dispense with additional surgical wound incision, utilization of an existing tracheostoma combined with the available guiding materials, the T-shaped tube can be readily inserted into the trachea; therefore, the surgical technique, non-invasively and safely and quickly inserting the T-shaped tube into the stenotic trachea elucidated in the invention is capable of safely and quickly manuvering patients with obvious subglottic stenosis to improve the prognosis without additional neck wound incision.
Claims11
A non-invasively and safely and quickly surgical technique of inserting a T-shaped tube into a stenotic trachea comprising steps as followed:
- (a) adopting a guide tube and inserting the guide tube into the T-shaped tube, protruding two ends of the guide tube respectively from a side arm and a lower arm of the T-shaped tube;
- after the step (a), (a1) confirming a status of the trachea, classifying according to an obstructed area of the trachea, wherein grade I is that an obstructed area of the trachea is less than or equal to 50%;
- grade II is that an obstructed area of the trachea is between 51% and 70%;
- grade III is that an obstructed area of the trachea is between 71% and 99%;
- and grade IV is complete (100%) obstruction of the trachea;
- when the status of the trachea is classified to grade II˜IV, performing a tracheal dilation procedure for the patient's narrowed trachea;
- and
- (b) clamping a lower arm end of the T-shaped tube with a clamping tool to make the lower arm end of the T-shaped tube to enter a distal trachea through a tracheostoma, so that the lower arm of the T-shaped tube and one of the ends of the guide tube entering the distal trachea;
- then clamping an upper arm end of the T-shaped tube with the clamping tool to make the upper arm end of the T-shaped tube to enter a proximal trachea through the tracheostoma, so that the upper arm of the T-shaped tube entering the proximal trachea;
- and inner fixing the side arm of the T-shaped tube into the tracheostoma;
- wherein when the step (a1) confirms that the status of the trachea of the patient is classified to grade II˜IV, the step (a) further comprises a suitable guide belt, putting the guide belt into the trachea, protruding out one end of the guide belt from the tracheostoma to the patient's mouth;
- subsequently, the guide belt is passing through the upper arm and the side arm of the T-shaped tube;
- in the step (b), by applying a pulling force to the mouth end of the guide belt, pushing the upper arm of the T-shaped tube into the proximal trachea.
