"I'm the instrument technician who worked at the county hospital yesterday. My name is Jiang Youwei." The instrument technician said with a smile.
Li Zheng said with a smile, "Hello, let me familiarize myself with today's equipment first."
"Yes, Dr. Li, you did a great job yesterday. I will do my best to cooperate with you today and perform the surgery beautifully."
"That's thoughtful!" Li Zheng said with a smile.
A good instrument technician will affect the smoothness of an operation. After all, if the instrument technician is not familiar with the instrument, he will have to think for a long time when you ask for it. The operation will be a bit frustrating and the surgeon will directly scold him.
Jiang Youwei began to introduce the equipment to Li Zheng one by one.
In his previous life, whenever Li Zheng went to a place to perform knife throwing, he would first familiarize himself with the equipment, because the equipment from different manufacturers would be slightly different. Although most of the equipment were similar, each manufacturer wanted to create its own characteristics and would design some unique equipment. If he was not familiar with it first, problems might occur during the operation.
After getting familiar with it, the operating table was ready.
Li Zheng turned around and saw two more people in the operating room, Zhou Ming and Zhang Yong.
There was a doctor at the door who wanted to come in, but was kicked out by Director Duan.
The sterility requirements for orthopedic surgery are very high, especially for joint surgery, where the sterility requirements are even more stringent.
In that era, there were no operating rooms with hundreds or thousands of floors, so the number of people observing the operation had to be strictly controlled.
Next to the operating table, a camera was set up on a tall tripod. The photographer, wearing a scrubs suit, was pointing it at the operating table and adjusting the focus.
Everyone take their seats.
Lin Xiaomei and the instrument technician moved the instrument cart next to the operating table.
Duan Jianhui stood opposite Li Zheng as the first assistant, Chen Dayong stood on Li Zheng's right as the second assistant, mainly responsible for the hook-revealing operation, and Zhu Qidong stood on Director Duan's left as the third assistant, responsible for lifting his legs to maintain the posture of his lower limbs.
Zhu Qidong was still a little unhappy.
Li Zheng particularly emphasized to him that the posture of the lower limbs is very important in hip replacement. If the posture is not adjusted properly during the operation and the angle of the prosthesis is not correct, it will seriously affect the effect of the operation and may even lead to failure of the operation. Therefore, the third aid is more important than the second aid.
Zhu Qidong's mood finally improved.
"Can we start recording now?" the cameraman asked.
Duan Jianhui looked at Li Zheng.
Li Zheng nodded.
"start."
Everyone focused their attention.
Li Zheng stretched out his hand.
Lin Xiaomei slapped the skin cutting knife into his palm.
Li Zheng chose the posterolateral incision of the hip joint, which is also the most commonly used incision and is easy for them to learn.
Starting from about 5 cm below and outside the posterior superior iliac spine, Li Zheng cut along the direction of the gluteus maximus fibers towards the back of the greater trochanter of the femur, with a length of about 15 cm.
Director Duan handed over the electric knife pen.
Li Zheng quickly performed subcutaneous hemostasis.
“Great swordsmanship!”
Duan Jianhui couldn't help but exclaim in admiration.
Zhou Ming stood behind Li Zheng and saw it clearly, and was a little shocked.
The skill of the surgeon can be seen from this one cut. No marking lines were made before the operation, but the skin cutting speed was still very fast, and the cut went through the fat layer and reached the fascia in one go.
Ordinary doctors would not dare to cut like this and would have to proceed layer by layer.
This is the result of skin incision reaching a certain level.
Zhang Yong stood on the footrest and frowned when he saw Director Zhou nod.
Zhou Ming turned around and looked at Zhang Yong. He knew that he didn't understand, but he didn't say much. Just because the skin was cut well doesn't mean that the subsequent operations will be easy.
Li Zheng then used an electric knife to cut the subcutaneous tissue and deep fascia in turn, and bluntly separated the gluteus maximus muscle fibers.
"Be careful to protect the sciatic nerve here." Li Zheng said as he pulled the inside of the sciatic nerve apart.
The external rotator muscles are then cut and turned medially to expose the hip capsule.
The T-shaped incision of the joint capsule revealed the dislocated femoral head and acetabulum.
Because the contracture was quite severe, Li Zheng loosened the tissues around the joint again.
Li Zheng did not hesitate or feel unconfident in every step of the operation.
He was like an experienced professor, who was very familiar with the procedure and made the operation look very simple.
"Doctor Zhu, internal rotation and flexion of the lower limbs, dislocation of the femoral head." Li Zheng said.
Zhu Qidong did as he was told, but failed the first time.
Director Duan helped and the dislocation was successful.
"See, lifting your legs is not that easy!" Duan Jianhui took the opportunity to educate him.
Zhu Qidong nodded, this indeed requires skill.
Then, Li Zheng asked Zhu Qidong to flex his legs extremely inward and internally rotated.
"The soles of your feet must be facing the ceiling. This is a reference for positioning," Li Zheng emphasized.
Zhu Qidong hugged his calves and tried hard to maintain this posture.
Next is the femoral neck osteotomy.
"Swing the saw." Li Zheng stretched out his hand.
Zhou Ming stood behind Li Zheng and asked with a frown, "Aren't you going to draw any marking lines?"
"No need." Li Zheng answered straightforwardly, showing strong confidence.
In my previous life, when I was doing a joint replacement, I would draw a marking line on the femoral neck. Later, after doing it more often, I could tell where to cut at a glance and did not strictly follow the textbook.
Zhou Ming frowned. This attitude was either reckless or well-planned. Just keep watching, you'll find out soon.
Duan Jianhui was a little excited. This step was crucial. Whether Li Zheng's operation was successful or not would be determined by this step.
Jiang Youwei immediately handed the oscillating saw to Li Zheng.
Duan Jianhui has proactively adjusted the acetabulum retractor to protect the surrounding soft tissue.
"How was the patient's blood transfusion routine check?" Li Zheng asked.
All surgical patients must be tested for hepatitis B, hepatitis C, HIV, and syphilis, also known as the four blood transfusion tests.
