Li Zheng has already treated the blood vessels.
The skin flap he removed matched the defect perfectly, and he first sutured the flap to the thumb skin with three stitches to initially secure it.
Li Zheng put on his microscope glasses again.
With the blood vessel transplant just now and the skin flap transplant next, no one had any doubt whether he could succeed.
Soon, the two blood vessels were sutured in less than 5 minutes.
Just when everyone thought Li Zheng was going to loosen the tourniquet to test the effect, Li Zheng had already started to prepare to suture the skin.
"You are very confident!" Duan Jianhui said with a smile.
Others think so too.
Li Zheng nodded and asked the circulating nurse to take off the microscope glasses.
Chen Dayong laughed and said, "When your realm reaches my brother's level, you will be more confident!"
Everyone shook their heads.
This flatterer! After the operation, Li Zheng's butt was beaten to pieces by him.
Soon, the flap was sutured.
When you see this perfectly covered skin flap, if you don’t look carefully, you might think that no surgery has been done here.
Li Zheng moved his joints and found that the range of motion was quite good.
Next comes skin grafting.
"Where should the skin be taken?" Bao Youshan asked.
This surgery is completely new to most people, so it is very novel.
"The skin repair requirements for the thenar eminence are not that high, so you can take it wherever is convenient!"
Li Zheng selected a small piece of skin on the inside of his right forearm, which is also the most commonly used area for hand skin grafting because the skin has good elasticity and is located in a hidden location.
After cutting, it is thinned and all subdermal tissue is removed.
The wound on the right forearm can be sutured directly.
"Prepare a pack of No. 0 silk thread." Li Zheng said while sewing the wound.
After the suturing is completed, the needle is threaded to prepare for the skin transplant.
I saw him poke a few small holes in the thinned skin with a sharp knife.
"What's the point of piercing the skin?" Bao Youshan's heart tightened. Wouldn't it be more difficult to heal the skin if it was broken?
Zhu Qidong couldn't bear to watch any longer and said coldly, "You know nothing about microsurgery. You don't even know the effect of such a basic operation!"
Although Bao Youshan is thin, he is thick-skinned and is also a person who is crazy about technology.
He didn't care what Zhu Qidong thought of him at all, and said with a smile: "Brother Zhu, you are an expert in this field, please teach me some basic knowledge!"
Seeing his respectful attitude, and the fact that this was the first time he had been respected today, Zhu Qidong felt much better. He nodded and said, "Wounds will always have exudate. If it can't be drained properly, it will accumulate under the skin, preventing the skin from fully adhering to the basement, leading to skin necrosis."
Bao Youshan's eyes lit up and he said, "These small holes are for drainage?"
Zhu Qidong smiled faintly and said, "Your understanding is quite good. You get it right away."
Bao Youshan chuckled and said, "It's mainly because Teacher Zhu teaches well!"
There are two flatteries in one short sentence.
Zhu Qidong felt very comfortable and nodded repeatedly, saying, "I've always been very generous. As long as you're willing to learn, I'll teach you!"
"Haha, that's great. Teacher Zhu, please come to our hospital more often in the future!" Bao Youshan said with a smile.
Zhu Qidong nodded and said, "Don't worry, with Teacher Li here, I will come here often!"
Bao Youshan looked at Li Zheng with burning eyes and said with a smile, "I am so lucky to have such excellent teachers like you two!"
This made everyone feel a little uncomfortable.
These two guys, singing the same tune, have really reached a certain level of flattery.
Xiang Yuanzhong and Duan Jianhui looked at each other, and were also considering whether to follow their example and flatter Li Zheng.
In just a short while, Li Zheng had already reattached the skin to the area on the thenar where the flap had been taken. A long piece of silk thread remained at the end of each stitch.
Zhu Qidong took the initiative to explain to Bao Youshan: "For this type of free-thickness skin transplant, the skin's nutrition is entirely provided by the exudate of the basal tissue. Therefore, after the skin graft is completed, the skin must adhere closely to the basal tissue. If it is not adhered tightly or moves, the skin will hardly survive, so it must be packed and pressurized."
Everyone understood his explanation.
These long lines left behind are used for packaging.
"One bottle of gentamicin." Li Zheng said.
The circulating nurse immediately broke open one, and Li Zheng picked up the syringe and drew out the liquid, then drew out a little saline solution to dilute it.
Through the small hole in the skin graft, inject the diluted gentamicin solution into the subcutaneous area for flushing.
Everyone can see that this step is to prevent infection.
After rinsing, Li Zheng carefully squeezed out the water under the skin with gauze, then wet a small cotton ball with gentamicin saline and pressed it on the skin.
Chen Dayong helped him press the cotton ball, and Li Zheng tied the baling lines on both sides into knots.
"The packing force cannot be too strong, otherwise the pressure effect will not be achieved. It cannot be too strong either, otherwise the thread will cut the skin and cause the operation to fail." Zhu Qidong acted as an explainer.
Everyone nodded.
Dean Zhang chuckled and said, "After hearing what you said, everyone now understands this operation better!"
Zhu Qidong nodded and said, "I'm happy to share my knowledge with everyone! Just like Teacher Li is willing to help everyone improve!"
hehe.
Everyone was a little bit overwhelmed. It seemed that this kid was completely conquered by Li Zheng, and he kept talking about Teacher Li.
Soon, Li Zheng finished packing.
Finally, cut the knot on the pressure bag.
"Loosen the tourniquet."
Li Zheng issued the final order.
The operation is officially over.
