This doctor is already middle-aged, and he's only just started practicing medicine.

Chapter 49 Review!
Emergency department, operating room.

Tong Yuan'an sat in the main operating position, his eyes resting on the eyepiece frame of the microsurgery microscope. His hands moved swiftly yet methodically within the operating field, smooth and effortless.

Lu Cheng sat upright beside his assistant's eyepiece, and could see very clearly the needle holder and needle tip in Tong Yuan'an's hand. When still, the needle was completely still, but when moving, it curved like a knife.

The chubby man held small microscopic instruments, moving swiftly and decisively within the cramped field of vision.

This is an unfamiliar suturing technique. You can see the influence of the modified Tang method and some of the concepts behind the Tsushita suturing technique.

However, Tong Yuan'an did not explain to Lu Cheng in detail what kind of suturing technique this was.

Chen Song, who was watching from the operating room, was speechless. After watching for a while, he sat down on a steel-faced wheeled stool, shook his head gently, and looked at the complicated scene.

In fact, when choosing his major, Chen Song understood that when it came to surgical techniques and specific surgical procedures, an emergency surgeon could never compare to a specialist.

Emergency surgeons only focus on hemostasis techniques that require extremely high time sensitivity.

But the art of stopping bleeding is a matter of life and death, a matter of life and death in a single thought, and cannot be "performed," and may even appear violent and bloody.

Chen Song never even considered comparing his surgical skills to Tong Yuan'an's; he was simply lamenting the widening gap between their techniques...

Peng Kun was also mesmerized, his eyes filled with envy, his mouth moving so fast that his surgical mask bounced up and down, and his breathing became rapid.

If he had the abilities of Tong Yuan'an, what was Lu Cheng? And what was Xiang Daihong, the deputy director of the state people's hospital?

I've heard of a limb replantation procedure. Could I just chop off this hand and attach it to my own? Helpless, Peng Kun could only fantasize in secret, while carefully observing Lu Cheng's expression.

This was actually the first time Lu Cheng had ever truly grasped the details of this level of operation. During his previous residency training, Lu Cheng's basic skills were extremely poor, and he could only skim through the surgeries performed by many professors.

As a resident in orthopedic training, Lu Cheng had also visited the hand surgery department of Zhongnan Hospital.

Tong Yuan'an's operating techniques differed from those used by several professors at Zhongnan Hospital, but his proficiency did not surpass theirs; in fact, it was slightly inferior to Professor Liu's...

But after all, Tong Yuan'an is only an associate professor, while Professor Liu is already a senior professor of hand surgery with many years of experience.

After finishing the tendon suture, Tong Yuan'an raised his chubby face and said, "Xiao Lu, could you take care of the rest of the skin cuts?"

Lu Cheng immediately nodded: "Okay, Teacher Tong."

After Tong Yuan'an put down the microscope, Lu Cheng took a deep breath, sat up straight, squinted slightly, and began to operate using the eyepiece.

Lu Cheng had never used an eyepiece before, so he was a little unaccustomed to operating it through one. However, after handling the microscope instruments a few times, he became familiar with the field of view...

Once he felt he was familiar with the area, Lu Cheng used micro-tweezers to lift the surface of the skin and began intermittent suturing.

After Tong Yuan'an raised his face, he immediately focused his gaze on what was in the eyepiece's field of vision.

As a master of hand surgery, he knows very well how to judge a person's basic suturing skills. The most basic skill is actually raising the hand, and when raising the hand, the hand must be steady.

Even under a magnifying glass, no creases should appear. If one cannot control this kind of focus, one cannot become a skilled hand surgeon.

Lu Cheng succeeded; you could tell from those few skillful maneuvers he executed.

If a person's hands are not steady, then during the operation and holding of the instrument, many creases will be created, which will be very clear and distinct in the eyepiece's field of vision...

Then, Tong Yuan'an looked up again and noticed that Lu Cheng's eyelids were blinking frequently, clearly indicating that he had not undergone formal training.

Tong Yuan'an didn't disturb Lu Cheng, but instead focused intently on the details of Lu Cheng's suturing. The angle of needle insertion, the choice of needle insertion point, the direction of needle insertion, the angle of needle exit, and the control of force throughout the process were all remarkably meticulous—this was the detail of real suturing…

If it's just skin suturing, the whole process is short, only about ten minutes. Lu Cheng then had Tong Yuan'an cut the last stitch.

After finishing the procedure, Lu Cheng used gauze soaked in saline solution to wipe the wound area. He then loosened the sutured wound opening with satisfaction and showed Tong Yuan'an that all the sutures were perfectly aligned with the skin to create tension.

This proves that all the stitches were under stress and at a consistent depth, with no slippage due to tension.

"Teacher Tong, can we put on the sterile dressing now?" Lu Cheng asked.

“Okay, let’s cover it up!” After confirming the details that Lu Cheng had shown him, Tong Yuan’an had no doubts.

Even the most outstanding professional PhDs in the department don't currently possess this level of suturing skill; anything beyond excellent is abnormal and cannot be generalized.

Lu Cheng's basic skills are already quite solid, even better than when he was the same age, and Tong Yuan'an couldn't find any fault with them.

However, after Tong Yuan'an got up and took off his green sterile surgical gown, he said, "Xiao Lu, you have a background in hand surgery, but your eyes are not good."

"Blinking too often. If you really want to specialize in hand surgery, you can only blink once every one or two minutes."

"It takes practice. You can hardly learn it without shedding a lot of tears."

"When suturing severed fingers, the opportunity to suture blood vessels is fleeting. If you miss it, you may have to wait again. Therefore, you must master the basic skill of not blinking."

"Furthermore, with your current basic skills, the next step should be to suture the severed tail artery of a nude mouse."

"The key to this progress lies not only in the handling of suture details, but also in the attention to knotting details; otherwise, slight creases will appear between blood vessels, creating turbulence!"

"The diameter of the tail artery in mice is already very small, and the blood flow is not abundant. If you tie a knot and indirectly retain some blood, it may affect the activity of the distal limbs."

"These are all unacceptable..."

"However, with your current basic skills, you're good enough to start practicing the Tajima suture technique."

"After this surgery is finished, I will take you to your hospital's skills training room and explain to you in detail the key points of learning the Tajima suturing technique."

As Tong Yuan'an spoke, his gaze shifted to Peng Kun, and he said in a teasing tone, "Young Master Kun, why don't you come along too?"

While Lu Cheng finished suturing and bandaging the patient, he also applied a plaster cast for external fixation.

After tendon suture surgery, it is actually best to use a brace for additional fixation, but custom-made braces are relatively expensive. Buying them online is cheaper, but no one can foresee their own injury, so the only option is to use a cheap plaster cast for temporary fixation.

Peng Kun immediately shook his head vigorously, his voice hoarse: "Professor Tong, I'll pass, I probably can't learn it..."

"This task still needs to be handed over to Brother Lu."

Peng Kun didn't even dare to compare his learning speed with Lu Cheng's, nor did he even dare to have such a thought, mainly because the gap between them in terms of basic sewing skills was too great.

Even if Tong Yuan'an's estimate of one or two years was a bit of an exaggeration, if it were just six months, I could learn it, but by then it would be too late.

Tong Yuan'an walked up to Chen Song with a calm expression and said casually, "Old Chen, shall we discuss this?"

Chen Song smiled and politely gave a single pinyin: "gun!"
