My daily work as a doctor: My treatment value is increasing.

"Hahahaha." Zhang Weimin was stunned. Listening to the lyrics and thinking about what he was doing, he finally understood why Lu Renxin suddenly laughed.

"Xiao Pei... really..." He shook his head helplessly, but his hands didn't stop moving. He reminded Lu Renxin, "Concentrate, don't just listen to the song."

The surgery is still ongoing, and Zhang Weimin has completed the suturing of the exposed mucosa inside the window.

He then inserted the TST stapler deeper, tightened the sutures, and pulled the hemorrhoid into the stapler chamber.

Pull the trigger hard, and with a crisp "click," the lesion is accurately and quickly cut and anastomosed.

After waiting a moment, he came out and pointed to the deeper part, reminding him:

"See these small ears that form in these locations? Remember to have them tied off."

Zhang Weimin gave him as much space as possible to observe. Lu Renxin turned his head and finally saw the few extra mucosal protrusions through the narrow hole.

He silently noted it down: details, these are all surgical details.

These issues should not be underestimated during surgery, as improper handling can easily affect the patient's subsequent recovery.

……

After the patient leaves, the next patient begins.

The anesthesiologist had already laid the patient down, and Lu Renxin saw the name on the medical record—He Dong.

He recalled the scene at the outpatient clinic, where a naive college student searched for symptoms online and concluded that he had hemorrhoids.

Lu Renxin remembered that he had a low-lying anal fistula.

Zhang Weimin took the medical record from Lu Renxin, glanced at it, closed it, turned to stare at him, and said with an unyielding authority:

You drive this one.

"Me?" Lu Renxin stood there dumbfounded, pointing his index finger at himself, looking at Zhang Weimin in disbelief.

Teacher, are you serious? I've only ever been an assistant.

Although he has been involved in surgeries for so long, he is familiar with the basic procedures, if not all of them.

Lu Renxin understands the principles behind each step and can even predict the surgeon's next move.

But... the first time he'd actually used a knife would be when a young woman got married.

The operating room nurse looked at the two of them with some hesitation and asked with concern in her voice.

"The surgery isn't particularly difficult, but it's still the surgeon's job... Lu is still a student, can he handle it?"

Sister Pei chimed in, "Yes, Director Zhang, why don't you do it yourself? Let him be your assistant, learn more before you start the surgery."

Lu Renxin's heart tightened. He knew that Sister Pei and the others meant well and were afraid that he would mess things up.

Zhang Weimin waved his hand, his tone relaxed but his attitude firm: "Don't worry, Xiao Lu's skills are definitely up to par."

"I know him very well. He's good at both theory and practice. Besides, with me as his assistant and keeping an eye on things, there won't be any problems."

He paused, his gaze sweeping over Lu Renxin: "Young people always need opportunities to practice; they can't just watch all the time. You won't learn anything from just watching."

"I believe him."

Trust—this is the trust Zhang Weimin placed in him.

Lu Renxin, who was initially anxious, relaxed after hearing the teacher's words.

The teacher has said so, showing the utmost recognition of his skills, so he can't let the teacher down.

Moreover, he was always learning. Every time he was an assistant, he would memorize the main surgical steps in his mind without any relaxation and imitate their techniques in private.

He believed in himself, so he replied, "Okay, I'll do it."

Lu Renxin switched places with his supervisor and sat in the surgeon's seat.

He took a deep breath, picked up the probe, and inserted it into the damaged opening, while simultaneously feeling the direction of the fistula with his fingertips.

Another long index finger was inserted into the anus and carefully touched near the dentate line.

Found it, the inner entrance is here.

After re-identifying the location, Lu Renxin determined that, based on He Dong's condition, anal fistula excision was the best option.

He used tissue forceps to lift the skin around the opening, pressed the electrocautery button, and a "sizzling" burning sound rang out, accompanied by wisps of white smoke.

Following the direction of the fistula, Lu Renxin made a precise fusiform incision.

Then, carefully begin to separate along the incision.

It is necessary to gradually peel away these fibrotic tissues caused by inflammation from the normal tissue.

The whole process requires a great deal of patience and meticulousness, just like digging a tunnel, to completely excavate the entire fistula buried underground, along with its inner and outer openings.

Until only healthy tissue remains.

That huge fistula was pulled out by the roots, leaving a deep pit.

He picked up a curette and carefully scraped the wound to make sure there was no necrotic tissue left.

Lu Renxin's forehead was covered in fine beads of sweat due to extreme tension.

But he didn't care and continued to pick up the electrocautery knife to prepare for spot hemostasis of the wound.

After a few "buzzing" sounds, it was finished.

For He Dong's type of low-lying simple anal fistula, suturing is not necessary; simply open and drain it to keep it patent.

The event was about to end, but Zhang Weimin didn't call a stop, so Lu Renxin continued.

Just as he was about to stuff the gauze into the wound, Zhang Weimin's voice suddenly rang out:

"Wait a moment."

Lu Renxin paused, then looked up at his mentor with a puzzled expression.

Zhang Weimin pointed to the edge of the wound: "Look here, it wasn't trimmed evenly enough, it's prone to swelling later."

Upon closer inspection, he indeed saw a small, slightly protruding section.

Lu Renxin quickly picked up the tissue scissors and carefully trimmed it flat.

Zhang Weimin was then satisfied: "We can continue."

Lu Renxin picked up the gauze strip again and inserted it evenly, layer by layer, from the bottom of the wound.

He performed the subsequent steps meticulously, each movement flowing smoothly as if he had rehearsed it countless times in his mind.

Zhang Weimin stood to the side, arms crossed, nodding slightly.

You truly are worthy of being my student.

[Congratulations, host, you have successfully completed surgery*1. Healing value +35]

Lu Renxin could hardly believe the numbers announced by the system.

What? 35?

The surgeon is definitely different.

But he also knew that behind the 35 points of healing value was the system's assessment of the technique.

When he's an assistant, he only needs to cooperate, but when he's the surgeon, there are many more things to consider.

Every detail and every aspect must be taken into account.

After each step, the next step must be considered immediately: whether the bleeding has been completely stopped and whether the drainage is unobstructed, in order to ensure rapid healing after the operation.

He finally breathed a sigh of relief after taking off his gloves and stepping off the stage.

Zhang Weimin patted him on the shoulder: "Well done, keep up the good work next time."

……

For the next six surgeries, Zhang Weimin did not have Lu Renxin serve as the lead surgeon.

Lu Renxin naturally returned to his position as assistant.

He was well aware of his mentor's pace. He Dong had the simplest case of low-lying simple anal fistula, and letting him handle it was a sign of trust and a test.

However, everything in excess is as bad as deficiency. The amount of knowledge he gained from just one machine was enough for him to digest, analyze, and learn repeatedly in his mind later.

If we let him operate two or three machines in a row today, that wouldn't be teaching, but a teaching accident; it would be forcing growth.
