Chapter 265 Replantation of severed fingers, a skill that shocked the audience!

Academician Chen couldn't hold it anymore, "Talk about science."

Yang Chenxi couldn't help but say, "Compared to Dr. Xu's surgical skills, I think it's more scientific that the popliteal artery is the mother's."

Everyone nodded silently.

Even if you sew your own umbilical cord in the womb, you won't have such a skilled vascular suture technique!

Continuous through suture method...

Intermittent suture...

Overlap suture...

And the U-type suture method demonstrated by the mouse tail before.

And so on, all of them were used by Xu Qiu naturally, and each anastomosis took the best plan.

Finally,

Xu Qiu covered the soft tissue bed and skin, completely buried the repaired femoral artery and popliteal artery in it, and put in a drainage tube.

"Check."

Xu Qiu closed his eyes as his voice sounded.

After staring at the microscope for a long time, his eyes were tired to the extreme, and he needed to relax.

"Release the hemostatic clamp!" Li Xue immediately commanded.

There are several manifestations of good blood circulation recovery:

The anastomosed blood vessels are well filled.

There is arterial pulsation at the distal end of the replanted body.

The skin of the replanted limb is ruddy, and the capillary filling time does not exceed two seconds.

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

In addition, the unanastomosed small vein ends bleed vigorously;

The moment the vascular clamp is released, the whole body's blood flows along the suture, through the artificial blood vessels, and then enters the autologous blood vessels at the lower end, and then returns to the heart through the venous system.

Dongdongdong——

Strong pulsation slowly appears in the arteries of the left lower limb, and the blood vessels are filled one by one.

Puff!

At the same time, the small vein ends that have not been anastomosed have spurted out streams of dark red blood.

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

"Good blood supply!" Yunmei said happily.

Xu Qiu opened his eyes, "Continue."

...

Ten minutes later, Xu Qiu completed the end of the vascular anastomosis.

This is the highlight of the assessment.

It is also the step that Yang Chenxi pays the most attention to.

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

He even began to reflect on whether he was qualified to be Xu Qiu's teacher.

However, for patients, blood vessel repair is still only a part of limb-saving surgery.

Then, there is muscle and tendon repair.

This is the key to limb function recovery!

Finally, nerve repair.

It determines the brain's control over muscles.

At this step, Wang Shengde also squeezed to the front, his eyes a little hot.

He was waiting for this moment!

When he learned that Xu Qiu was going to have artificial blood vessel repair, Wang Shengde was not very interested.

He knew that Xu Qiu would definitely perform exceptionally well.

But, after knowing that this was a limb-saving surgery, Wang Shengde could not sit still.

Although it is a lower limb replantation, but... this is essentially the same as the replantation of severed fingers in hand surgery.

The steps are to fix bones, repair blood vessels, repair tendons, and suture nerves!

If someone else did the lower limb replantation surgery, Wang Shengde would never associate it with other hand surgeries.

But, this is Xu Qiu!

If Xu Qiu can do lower limbs, then... is he also capable of replanting severed fingers!

Since the year when Wang Shengde was 38 years old, he was cut off by the patient who kindly saved him when he was in high spirits. He has left the operating room since then.

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

For example, continuous stellate ganglion block under ultrasound guidance, application of non-shortened phalangeal microsurgery; vascular anastomosis free wrist transverse composite tissue flap bridging wound repair non-shortened severed finger replantation, etc.

Wang Shengde's talent was too amazing back then.

After leaving clinical surgery, the theoretical research he came up with was even more whimsical and too difficult, so there were not many doctors willing to verify it.

And there was not a single patient willing to cooperate with him in clinical experiments and efficacy evaluation.

Once a hospital accepted Wang Shengde's suggestion and adopted continuous stellate ganglion block, which eventually caused vasospasm and lost the opportunity to replant two fingers.

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

Therefore, although Wang Shengde now has a good position in hand surgery, he also has many titles behind the scenes.

"Paper talk".

Because up to now, Wang Shengde's work is basically on diagnostic standards and medication guidelines, and his contribution to clinical surgery is almost zero.

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

This is actually a kind of irony.

But Wang Shengde saw hope in Xu Qiu!

Other doctors cannot realize the ideas proposed by Wang Shengde.

But... can Xu Qiu not do it?

Difficulty has never been a factor that hinders Xu Qiu. If he can do lower limb replantation, why not do another hand surgery finger replantation!

"Really..." Wang Shengde looked at the surgical area.

At this time, Xu Qiu had already started muscle and tendon repair.

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

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

Repairing the main extensor and flexor muscle groups can restore 70 to 80 percent of the function of the lower limbs.

“The thigh is primarily a repair outside of the quadriceps, hamstrings and vastus adductors.”

"The calf is composed of the posterior triceps and tibialis anterior, peroneus longus and short muscles, gastrocnemius and soleus muscles, extensor and flexor muscles of the hallucis and toes..."

Wang Shengde whispered, his eyes fixed on the surgical area.

Time passed, and the muscles were sutured one by one.

Mushroom suture.

Xu Qiu seemed to have eaten a sewing machine, and each stitch fell exactly between the myometrium and fascia at the edge of the rupture.

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

Next, the tendons on both sides were sutured.

"1-0 nylon thread."

Xu Qiu stretched out his hand and summoned the instrument.

Then, the double-needle intratendon suture method was reproduced between the severed tendons.

Wang Shengde's pupils contracted.

This is the double-needle intratendon suture method created by Professor Wang Chengqi, the master of microsurgery in Daxia!

The advantages of this procedure are obvious. It saves time, is smooth, and reliable, and has less impact on the blood circulation of the tendon, but it is quite difficult, and few doctors will be specially trained in this suture technique.

The reason is that the conventional end-to-end suture has a difficulty coefficient of 0.4 and a suture effect of 80 points.

The difficulty coefficient of the double-needle intratendon suture method is 0.8 and the suture effect is 90 points.

The difficulty is doubled, and although there is an improvement after suture, the magnitude is too small.

Few doctors will train specifically for this, and spend a lot of time to improve this subtle suture, which is not worth it and unrealistic.

However, what shocked Wang Shengde was not the difficulty of this suture technique.
