The news that Li Zheng came to the city hospital for surgery quickly spread throughout the surgical system.
In Li Zheng's operating room, many doctors wanted to go in and observe, but were driven out by the head nurse.
More and more doctors are entering the live studio to watch the surgery.
"Wow, your department actually invited Li Zheng back to perform the surgery. You are so brave!" said a urology doctor.
"Tsk tsk tsk, you dare to invite back a person who was fired from the hospital. Isn't that a slap in the face of the hospital?" said another urology doctor.
An orthopedic surgeon snorted coldly and said, "No matter who it is, as long as he performs surgery well, we can't go wrong by inviting him back to promote the development of the department!"
"Is he really that good at orthopedic surgery? Is it worth it for you to take the risk of being punished by the hospital to hire him?" The fat doctor from the general surgery department asked curiously. Li Zheng and he used to be in the same department, and he knew very well what Li Zheng's abilities were. But now he is a little confused.
Other doctors had the same question.
"Whether it's good or not, you'll know after you see it." The orthopedic surgeon didn't want to explain any more. After all, he had the same idea at the beginning, but he would no longer think so after seeing the surgery.
Everyone stared at the small color screen.
In the picture, Li Zheng is holding an electric drill and starting to fix the fracture.
I saw him align the radius and ulna, then insert two Kirschner wires into the bones on both sides of the broken ends, cross-fix them, and finally cut the Kirschner wires.
"That doesn't make any sense!" said the urologist.
"Don't talk, just keep watching and you'll know!" the orthopedic surgeon said with his eyes wide open.
Soon, after Li Zheng fixed it, he began to suture the extensor tendon on the dorsal side of the wrist.
Li Zheng's voice came from the TV.
"Dayong, do you know why we have to suture the tendon first, and the tendon on the back of the wrist?"
Chen Dayong nodded and said, "Sew the tendons first. Tendons are more resilient and will have less impact on the blood vessels and nerves even if there's some traction. If you suture the blood vessels and nerves first and then the tendons, it's bound to cause further damage to the blood vessels or nerves."
Li Zheng nodded and said, "That's only part of the reason. The main reason is that after tendon suturing, it can maintain the tension and stability of the limb, providing a relatively stable soft tissue environment for subsequent vascular and nerve anastomosis, reducing the risk of vascular and nerve displacement during the operation. After the tendon tension is adjusted, the limb position is relatively fixed, which is conducive to accurate vascular anastomosis."
Everyone nodded, this was a very professional explanation.
Li Zheng continued, "The second question is, the extensor tendons are superficial, all under the skin on the back of the wrist, making them easy to operate. First, repair the extensor tendons and adjust them to normal tension. Then, when suturing the flexor tendons, you can refer to the tension of the extensor tendons. This will ensure that the fingers can actively complete a full range of motion after surgery..."
Li Zheng explained while operating.
The more they listened, the more fascinated they became.
So professional!
This is simply practical teaching!
Everyone gradually understood why they invited Li Zheng to perform the surgery.
"He explained it in such detail that even I, a general surgeon, learned it!" said the chubby doctor.
"I can tell that Li Zheng has very solid theoretical knowledge of microsurgery and pays great attention to details. For microsurgeons, operations performed in this way will definitely have good postoperative functions!" said the urologist.
The orthopedic surgeon was completely immersed in Li Zheng's operation and no one paid any attention to them.
Li Zheng began to suture the tendon, and everyone focused their attention because this was the operation that truly demonstrated microscopic technology.
Li Zheng was seen holding a needle forceps in his right hand and a small pair of tweezers in his left hand to pinch the radial carpi longus tendon, and quickly sutured it using a suturing method that they could not understand.
"Can someone explain to me what kind of tendon suture method Li Zheng used? I've never seen it before!" said an orthopedic surgeon.
Another orthopedic surgeon said disdainfully, "You talk as if you know a lot about microsurgery... I don't know either."
Nobody knows.
Li Zheng's voice was heard again on TV.
"This suturing method is a modification of the original Kessler method and is more suitable for extensor tendon suturing..."
Everyone nodded, as if they understood.
Suddenly, Zhu Qidong's voice came from the TV again, "Doctor Li, what you said is so exciting. I want to do it with you!"
Director Duan shouted, "Nonsense! Focus on the operation!"
Zhu Qidong fell silent, and Li Zheng's voice came again: "Don't worry, I will sew up your left hand with you later!"
Zhu Qidong's steady voice came again: "Director Zhou, concentrate on the operation!"
What follows is the lengthy process of tendon suturing.
Li Zheng sutured the tendons of the radial carpi longus and brevis, extensor digitorum communis, extensor digiti minimi, and extensor carpi ulnaris in turn.
The doctors in the live broadcast room, except for those from orthopedics, who were from other departments, left one after another, but more doctors came in to watch.
In operating room No. 7.
After Li Zheng sutured the tendon on the back of his wrist, he picked up his arm and moved his wrist joint.
"It can flex 30 degrees and extend 20 degrees, with no restriction of movement and no problem in suturing," said Li Zheng.
Chen Dayong laughed, "Why bother checking? There must be no problem!"
Li Zheng shook his head and said, "This is just a demonstration for you. I can do it myself without checking!"
Chen Dayong laughed and didn't feel embarrassed.
Li Zheng finally sutured the extensor retinaculum on the dorsal side of the wrist and buckled all the extensor tendons to the joint.
Turn your wrist over again.
The tendons on the palm side are more complicated. There are 10 tendons in the carpal tunnel, and the median nerve also passes through it, so suturing is more difficult.
Li Zheng started from the deepest digitorum profundus tendon and used the "Tang-style" suture method.
"Each tendon has three loops, so that the suture can be sutured with maximum strength. Because the strength of the flexor tendon is very strong, unintentional contraction may cause the suture to tear..."
Li Zheng was sewing and teaching at the same time, and he was very fast.
Chen Dayong was very receptive and quickly figured out the routine of this suturing method.
The cooperation between the two also reached a new level.
It takes 2 minutes to suture one tendon, and after more than 20 minutes, all the tendons are sutured.
Put on your microscope glasses.
Next, Li Zheng sutured all the arteries and veins at a faster speed.
Half an hour later.
Li Zheng put down the equipment in his hand and said to the circulating nurse: "Loosen the tourniquet!"
All the doctors felt nervous.
They all gathered around quickly.
"Li Zheng, you've made that needle holder smoke!" Director Duan laughed. For him, the sooner the surgery was done, the better.
The head nurse came over personally to turn the valve of the tourniquet.
As the deflation ends, the entire right hand begins to turn red.
The terminal capillaries are well filled and the venous return is smooth.
"No problem!" Director Duan concluded.
The other doctors nodded vigorously.
"Continue the operation!" Director Duan did not waste time, his task was not yet completed.
Other doctors were immediately in place.
Li Zheng took a look and started to suture the nerve.
