  The blood in the subcutaneous tissue must be coagulated first. At this time, two large fan-shaped muscles called the platysma can be seen first. The platysma is a superficial muscle that doesn\'t connect to the bone. There are two muscles on either side of the neck that allow the mouth to open downwards.

   Do you think there are two neck muscles? No, it\'s too much muscle. Human neck muscles not only control the neck, but also control the mouth and tongue. These muscles also connect the head and the chest. They have many functions. Of course, the number of muscles responsible for work must be sufficient. Therefore, under the platysma, there is the sternocleidomastoid muscle, the scapulohyoid muscle, the thyrohyoid muscle, the sternohyoid muscle, the sternothyroid muscle, and the above is only the subclavian muscle group of the anterior cervical muscle. A minor operation, the surgeon\'s anatomy can be taken out and tested in the field. The doctor should be very familiar with these muscle groups and use dissecting forceps to separate them, while the assistant should use a retractor to help open the exposed organs. Handle these muscles with care to avoid strains that directly affect the patient\'s body functions. The anterior neck area is mainly veins, and the artery and recurrent laryngeal nerve are on the outside of the trachea.

   The main surgeon concentrates on dealing with the fascia covering the surface of the organs. The superficial fascia is the fascia of the sternocleidomastoid muscle, and the deep fascia includes the fascia of the sternum and thyroid. The fascia is cut with dissecting scissors. Before the trachea can be seen, a brown-red tissue like two butterfly wings can be seen first, which is the thyroid gland. The location of the thyroid on the trachea is called the isthmus. To do a tracheotomy, the isthmus covering the trachea must be pulled up slowly with a small hook with a small force.

   All the experienced surgeons are present. They are fast and steady when doing these dissections. It can be said that their eyesight is super accurate. Just take a glance and immediately know where and where the surgery is.

   After exposing the trachea, it’s time to cut the trachea. The main knife takes a sharp blade at this time to make an arc incision at the tracheal ring. Suddenly, everyone paused when they saw the tip of the scalpel held by Zhang Huayao.

Every action of    that is different from daily life has extraordinary meaning. At this moment, the tip of the knife is dull, no need to think about it, it must be the boss who feels that something is wrong.

   is a wave, and the wave of tissue life is conveyed to the tip of the knife and to the doctor\'s hand. The doctor\'s experience and intuition is sensing whether this fluctuation is normal during the operation. If it is not normal, it is likely to correspond to other sudden conditions. So, doctors need to be prepared.

   For this reason, Xie Wanying saw that Teacher Fu on the opposite side had been making preparations for blood-sucking.

   Zhang Huayao gave the surgical team members around him a look: Pay attention. Prepare for a shock wave.

  Other people slammed their heads, thinking that there was no other option.

   "Ready for blood transfusion." Liu Yu turned around and explained to the anesthesiologist.

  The anesthesiologist and nurse went to get blood, ready for the patient\'s possible hemorrhage.

   All the members of the operation were mentally prepared, Zhang Huayao didn\'t delay, and he slashed with the tip of the knife.

   The sharpness of the surgical blade can be imagined, the sharp knife is definitely a sharp knife, and it must be bottomed out if it is sharp enough.

   Hiss, the trachea was torn open like a piece of paper. It was like seeing another world inside, and blood flowed out.
