Academician Chen couldn't hold back anymore, "Tell me some science."

Yang Chenxi couldn't help but say: "Compared with Dr. Xu's surgical level, I think the popliteal artery is more scientific."

Everyone nodded silently.

Even if you use your own umbilical cord to play in the womb, you won’t have such skilled blood vessel suture skills!

Continuously penetrated suture...

Intermittent suture...

Studding stitching...

There is also the U-style suture method that has been shown on mouse tails before.

Wait and wait, all of them were naturally used by Xu Qiu, and each match was adopted, and the best solution was adopted.

at last,

Xu Qiu covered the soft tissue bed and skin, buried the femoral artery and popliteal artery that had been repaired completely, and placed a drainage tube.

"examine."

Xu Qiu closed his eyes as he heard his voice.

After staring at the microscope for a long time, his eyes were exhausted to the extreme and he needed to slow down.

"Relax the bleeding clip!" Li Xue immediately directed.

There are several symptoms of good blood circulation recovery:

The anastomotic blood vessels are well filled.

There is arterial pulsation at the distal end of the reimplantation.

The skin of the re-implant limbs is rosy and the capillary filling time is no more than two seconds.

The skin temperature of the replanted limb gradually rises to near normal.

And, the ends of the unansmotic venous bleeding is vigorous;

The moment the blood vessel clamp is loosened, blood flows throughout the body along the suture mouth, passes through the artificial blood vessel, and then enters the autologous blood vessel at the lower end, and then returns to the heart through the venous system.

Dongdongdongdongdong-

A powerful pulsation slowly appeared in the arteries in the left lower limbs, and blood vessels also filled with them.

Puff!

At the same time, dark red blood spurted out from the end of the small vein that had not yet been matched.

This means that the circulation from the heart to the artery, and from the artery to the vein is completely unblocked!

"The blood supply is good!" Yunmei said happily.

Xu Qiu opened his eyes and "Continue."

...

More than ten minutes later, Xu Qiu completed the end of vascular anastomosis.

This is the highlight of the assessment.

It is also one of the steps that Yang Chenxi pays most attention to.

Obviously, judging from Yang Chenxi's silent and shocked expression, Xu Qiu won his recognition.

Even, he began to reflect on whether he was qualified to be Xu Qiu's teacher.

However, for patients, blood vessel repair is still only part of limb conservation surgery.

Subsequently, there is muscle and tendon repair.

This is the key to the recovery of limb function!

Finally, it is nerve repair.

It determines the brain's control over muscles.

At this point, Wang Shengde also squeezed into the front, his eyes a little hot.

This is the moment he is waiting for!

When Wang Shengde learned that Xu Qiu was going to do artificial vascular repair, he was not very interested.

He knew that Xu Qiu's performance would definitely be extremely outstanding.

However, after knowing that this was a limb-protecting operation, Wang Shengde couldn't sit still.

Although it is a lower limb replantation,... this is essentially similar to the broken finger replantation in hand surgery.

The steps are all about fixing bones, repairing blood vessels, repairing tendons, and suturing nerves!

If someone else had lower limb replantation surgery, Wang Shengde would never think of other hand surgery.

But this is Xu Qiu!

If Xu Qiu can do lower limbs, then... is he also capable of replanting the broken fingers?

Since he was 38 years old, Wang Shengde was cut off his tendons by a patient who was kindly rescued when he was most energetic, and he left the operating room since then.

Over the years, he has been conducting in-depth research on the theoretical level of hand surgery.

For example, continuous stellate ganglion block guided by ultrasound, microsurgery for not shortening of phalanx; composite tissue flap bridge wound repair without shortening of finger breaking, etc.

Wang Shengde's talent back then was amazing.

After leaving the clinical operation, the theoretical research he created was even more whimsical and difficult, so there were not many doctors willing to verify it.

None of the patients who were willing to cooperate with him in clinical experiments and evaluation of the efficacy.

A hospital once accepted Wang Shengde's suggestion and adopted continuous stellate ganglion blocks, and finally vasospasm occurred, and the two fingers lost the opportunity to replant.

Since then, no one has been willing to adopt the extremely difficult techniques proposed by Wang Shengde.

Therefore, although Wang Shengde has a good position in surgery now, he also has many titles behind his back.

"Talking about war on paper".

Because now, what Wang Shengde does is basically diagnostic standards and drug guidelines, and his contribution to clinical surgery is almost zero.

The most amazing hand surgery genius who was once the most amazing, did not contribute much to the surgery in the end.

This is actually a kind of irony.

But Wang Shengde saw hope in Xu Qiu!

Other doctors cannot realize these ideas proposed by Wang Shengde.

But... Xu Qiu can't do it either?

The difficulty has never been a factor that hinders Xu Qiu. If he can replant the lower limbs, what's wrong with replanting the broken fingers of his hand surgery?

"Is it really possible..." Wang Shengde looked at the surgical area.

At this time, Xu Qiu had already begun to repair his muscle tendons.

The lower limbs are mainly load-bearing, so the requirements for muscle and tendon repair are much lower than those for upper limbs.

There is no need to accurately control every finger and use every muscle group.

By repairing the main extension and flexor muscle group, you can restore 70% or 80% of the functions of the lower limbs.

"The thighs are mainly repaired outside the quadriceps, hamstrings and adductors of femoris."

"The calf is the posterior triceps and tibial anterior muscle, the peroneal longus and gastrocnemius muscle and soleus muscle, the thumb, toe extension, flexor muscle..."

Wang Shengde whispered, his eyes always staring at the art area.

As time passed, muscles were stitched together.

Stupid stitching.

Xu Qiu was like eating a sewing machine, and each stitch fell between the sarcoid and the fascia at the broken edge.

In order to avoid hematoma and cavity, Xu Qiu also sewed a few stitches in the center of the thick muscle abdomen.

Immediately afterwards, the suture of the tendons on both sides.

“1-0 nylon thread.”

Xu Qiu stretched out his hand and summoned the equipment.

Subsequently, double-needle intra-tendon suture reappears between the disconnected tendons.

Wang Shengde's pupils contracted.

This is a double-needle intra-tendon suture method founded by Professor Wang Chengqi, a master of microsurgery in Daxia!

The advantages of this surgery are obvious, time-saving, smooth and reliable, and affecting the blood circulation of the tendons is less difficult, but it is quite difficult. Few doctors will specially train this suture technique.

The reason is that conventional opposite suture is adopted, with a difficulty coefficient of 0.4 and a suture effect of 80 points.

The double-needle tendon suture method has a difficulty coefficient of 0.8 and a suture effect of 90 points.

The difficulty is doubled. Although it has been increased after stitching, the amplitude is too small.

Few doctors will train specifically for this, spending a lot of time to improve this subtle suture, which is not worth it or realistic.
