Zhou Litao disinfected the patient's wound and injected the anesthetic before he began to perform a tracheotomy.
From the lower edge of the artillum to the upper sternum, the skin and subcutaneous tissue were cut along the median line of the neck. He used a hemostatic forceps to separate the pectoral hyoid muscle and sterebragus muscle along the median line, exposing the thyroid Gorge.
The patient's thyroid Gorge was too wide and blocked his vision. Zhou Litao separated the lower part slightly and used a small hook to pull the gorge upwards.
After confirming the trachea, he used a sharp blade to cut open the front wall of the ring of the windpipe in an arc from the bottom to the top at the third ring of the windpipe to form an anterior wall petal of the windpipe.
