Chapter 431: Chapter 210: Direct Surgery, Bone Sawing (3)

For example, in the past, Li Jingsheng could truly perform a direct laparotomy with one incision—skin layer, fat layer, anterior sheath, rectus abdominis layer, peritoneal layer, all five layers. An experienced surgeon would cut layer by layer.

But for a novice like Li Jingsheng, he would make a direct cut through all five layers.

Maybe even deeper.

The scalpel is sharp, and if you lack experience or technical skills, you don’t really feel the depth when cutting.

You really can’t tell the depth.

At this moment, as he held the scalpel, he carefully made a longitudinal incision from the patient’s radial-sided wrist flexor tendon.

With one stroke, it cut so smoothly that blood immediately gushed out.

Fortunately, the bleeding wasn’t too much.

The epidermis has a dense network of capillaries, which even the most skilled doctors cannot avoid. Some capillaries will inevitably be severed.

This is why it’s said that surgeries should be avoided if possible.

Because even the smallest surgery can harm the patient’s body.

Doctors will strongly recommend surgery only when they believe its benefits far outweigh its harms.

This is commonly known as meeting surgical indications.

No one is forced, it all depends on the will of the patient and their family.

If they disagree with the procedure, doctors can’t do anything.

"Dr. Li’s cutting technique is so adept, he must have practiced before. Very well done, keep going."

At first, Professor Wu didn’t dare speak for fear of distracting Li Jingsheng during the surgery.

He only praised him after Li Jingsheng raised the scalpel.

Watching Li Jingsheng make the incision earlier, he was actually quite nervous.

Even though he had witnessed Li Jingsheng’s sharp dissection technique, he was still worried about him messing up.

After all, incision and dissection are somewhat different.

Incision is a basic surgical skill; sharp dissection can be considered an advanced skill.

It’s more advanced and technically challenging.

Li Jingsheng couldn’t help but smile wryly; in the past at the First Hospital, his superiors didn’t even let him retract a hook, yet now they dared to let him operate on a patient?

But he did not explain anything.

Heroes shouldn’t be asked about their past.

Although he performed poorly in the past, he is now stronger, with little relation to his past.

He carefully made an incision on the side of the patient’s wrist, curving radially from the distal triquetrum tubercle and terminates distally at the radius.

"Separate the tissues with the forceps!"

Li Jingsheng directed Ruan Xiaoqin to work. 𝒻𝑟ℯℯ𝑤𝑒𝑏𝑛𝘰𝓋𝑒𝓁.𝒸𝑜𝘮

"From where should I separate it? Dr. Li, please guide me more clearly, I’m afraid of messing up."

Ruan Xiaoqin didn’t dare show off at this moment.

If she tears important tissues or injures blood vessels or nerves, the consequences would be severe.

"Pull the radial-sided flexor tendon towards the ulnar side and the radial artery towards the radial side. Expose the palmar wrist joint capsule."

Li Jingsheng looked at the radial artery and secretly sighed in relief, thankful for upgrading his skin incision technique.

Otherwise, if he accidentally severed an artery, the consequences would be dire.

When he made the incision earlier, he could feel a relatively distinct tactile sensation of the knife.

The tactile sensation of cutting skin and subcutaneous tissue was noticeably different.

And when he was close to the radial artery, he could feel the tactile sensation becoming much ’stickier.’

The resistance clearly increased step by step.

But he still couldn’t clearly distinguish small blood vessels and nerves based on the knife’s sensation.

Larger vessels could be avoided or recognized beforehand.

During the incision, he had already recalled the anatomy diagrams from his books in his mind.

He knew where the blood vessels and important nerves were.

He definitely wouldn’t just blindly cut like a fool.

The Master Level incision technique gave him a sense of the scalpel but was still not sharp and clear enough.

"Professor Wu, I’m now planning to make a longitudinal incision along the triquetrum tubercle joint capsule, do you think that’s okay?"

"It’s completely fine, just be careful. Damaging the joint would cause significant trouble."

After obtaining permission, Li Jingsheng cautiously cut open the joint capsule.

His proficiency in incision techniques was rapidly improving, and his life points seemed to have surged twice.

He briefly checked and saw his life points balance increase from 150 to 357.

It rose by a total of 207 points.

Surgeries, particularly as the primary surgeon, earn quite a lot.

The rate of increase was incredibly fast.

Later, he had to handle bone flap harvesting, grafting, and bone sawing; if all those were done by him, it should increase significantly again.

After opening the joint capsule, he carefully lifted the capsule attached to the surface of the triquetral bone and adjacent radius.

His life points increased by another 5 points.

What a refreshing feeling.

At this moment, the triquetrum and the unhealed area were already exposed.

"Micro drill!"

Li Jingsheng said to the nurse.

Now it was time to saw the bone.

"Dr. Li, although bone sawing isn’t technically demanding, it must be steady and slow; do not rush. One of my students rushed while sawing and ended up slicing off a piece of the patient’s soft tissue, causing massive bleeding and huge trouble."

Professor Wu seemed very nervous, watching closely from the side.

He even used a student as a cautionary tale.

The micro drill is quite handy, as is the electric knife; it’s nothing like the imagined massive, murderous electric saw.

Li Jingsheng’s current Master Level incision technique ensures his hands are very steady and accurate.

He felt no pressure operating the micro drill.

He carefully sawed off the hardened bone edge.

He checked and had already fully exposed the fracture surface.

His life points immediately surged by another 102 points.

This was probably due to sawing bone for the first time.

His life points had increased to 459.

It gave him a surreal feeling. The increase was too exaggerated.

But he also knew very well that this was the initial high gain; the next time he performs a similar surgery, the life points would increase more ordinarily.

He checked the scaphoid joint and began to carefully remove the scar tissue in the fracture gap.

Scar tissue isn’t a tumor, but its nature can be quite similar—stimulation can lead to proliferation.

It’s something that causes headaches for doctors and suffering for patients.

"Hand me the spherical rasp for a moment."

After removing the scar tissue, Li Jingsheng accepted the spherical rasp handed by the nurse, and began to polish the hardened bone.

It seems dentistry also uses this tool.

Orthopedics is a rather intense medical field, with electric saws, hammers, and rasps available, complete with blood.
