Chapter 128 Nerve Transplantation 【Please collect!Please subscribe! 】

As for Kong Xiang's "service" period is only three years, Zhang Zifan is not worried about this at all.

After all, with the development speed of Haoran Hospital, if Kong Xiang cannot stay willingly after three years, his own dean will have failed too much.

Therefore, Zhang Zifan didn't feel that he was cheating Kong Xiang at all.

They were all people who bid farewell to the operating table, but now they come to help Haoran Hospital set up an ophthalmology center.

……

In addition to building the [Intermediate Ophthalmology Center], Zhang Zifan must also ensure the effect of the surgery.

To be honest, although microsurgery is also Zhang Zifan's strong point, there is still a gap with head and neck surgery in terms of level.

However, in the final analysis, microsurgery is a department that requires a lot of equipment. The technology is insufficient, and equipment can be used to make up for it.

Sophisticated equipment and excellent suturing techniques are the original strength of microsurgery.

……

Zhang Zifan opened the system and found the storage column.

Now in the storage bar, there are three things in total.

【Zhanzhan Card X5】You can copy and paste an existing piece of equipment, but exclusive items such as [Self-aiming bur] and [Dean's pen] cannot be pasted.

[Advanced Morgue Drawings] Based on this drawing, you can design an unforgettable and excellent morgue.

[Ornn's Inferior Furnace] can permanently upgrade the level of a piece of equipment below green, CD time: 6 months.

What Zhang Zifan was looking for was this 【Ornn's Inferior Furnace】.

It was opened by Zhang Zifan from the mysterious treasure chest rewarded by the Kading event.

[Ornn's Inferior Furnace] is a relatively weak equipment, with a long CD time and can only upgrade low-level equipment below green.

[Common equipment (white), enhanced equipment (blue), special equipment (green), rare equipment (purple), rare equipment (pink), epic equipment (orange), artifact (unknown)]
But Zhang Zifan didn't expect that this tasteless piece of equipment would come in handy so soon.

Zhang Zifan came to the operating room and found a whiteboard surgical microscope produced by the system.

[A mediocre surgical microscope can slightly improve the accuracy of surgery]

Zhang Zifan took it back into the system, and then threw it into [Ornn's Inferior Furnace] for refurbishment.

As the raging flames rose, about 15 minutes later, a blue light flickered in the furnace, and a brand new piece of equipment appeared:
[A well-made surgical microscope, each part shows the spirit of craftsmanship, and the hand-grinded Zeiss lens inherited from fifteen generations can make you more comfortable in surgery]

……

A worker must first sharpen his tools if he wants to do well.

With reliable equipment, Zhang Zifan also has a bottom line in his mind.

Two days later, he summoned the surgical team again to prepare for Kong Xiang's operation.

According to the wooden barrel theory of Bad Street for more than ten years, the ability of a team depends on the shortest piece of wood in the team.

The anesthetized vegetable chicken, Su Feixiang, was obviously the shortest piece of wood in Zhang Zifan's team.

So Zhang Zifan wisely asked him to continue watching the show, instead of treating Kong Xiang as the first patient.

Kong Xiang was obviously very surprised why Zhang Zifan, the chief surgeon, came to anesthetize him, but as the medicine was pushed into the indwelling needle tube, he fell into the boundless darkness with a lot of question marks.

……

Although several plastic surgeries have been performed, shocking scars can still be seen on Kong Xiang's body.

Opening the operation area, Zhang Zifan found that the problem was indeed serious.

The motor and sensory functions of the hand are innervated by the median, ulnar, and radial nerves, respectively, from the roots of the brachial plexus.

According to the part of Kong Xiang’s hand that lost function, the damage was mainly to the radial nerve.

Using the marked points to dissect the radial nerve, Zhang Zifan found that his situation was actually somewhat similar to Li Jingwang's.

That is, due to the greater damage, more tissue loss, and greater tissue tension.

It's just that the two contracted, one is a nerve and the other is a tendon.

Kong Xiang had already undergone surgery by a master of microsurgery before. Through ingenious surgery, the two ends of his originally severed radial nerve had been tension-reduced and sutured together.

This kind of suturing technique is not comparable to that of the doctor before Li Jingwang.

But it is clear that no matter how much the tension is reduced, a clever woman cannot cook without rice, and the tension between the two nerves still exists objectively.

The nerve is sutured under tension, which has two consequences.

The first is that the nerve sutures are prone to tiny nascent tears.

The second is that there will be a certain gap between the stumps of the two nerves, which will easily lead to the formation of scar tissue.

Both tiny tears and scar tissue can block the passage of nerve fibers, causing poor nerve signal transmission.

This is the main reason why Kong Xiang has successfully connected the nerves, but still cannot recover the sensation and motor function of his hands.

"Boss, is there any possibility to further loosen the tissue and reduce the tension?"

Yuan Qiang raised a question.

Kong Xiang's nerve butt joint operation was actually very beautiful, and the nerve bundles were joined very neatly, showing superb surgical skills.

It is a pity to destroy such an operation result so easily.

"No, that's just repairing the broken ship, and it still can't stand the storm!"

Zhang Zifan shook his head and rejected Yuan Qiang's proposal.

In fact, he has already used the [Eye of Preset] to investigate. If the tension is further reduced, the surgical effect can only be restored to 30% of the original function at most.

Even if the left hand is not Kong Xiang's dominant hand, 30% of the function will still have a major impact on the operation.

Zhang Zifan had to find a more thorough treatment.

In fact, Zhang Zifan knew this method, Yuan Qiang knew it, and even Kong Xiang himself knew it.

That is nerve transplantation.

The reason why Kong Xiang rushed to Haoran Hospital immediately after seeing Fang Guohua's operation report was precisely because Fang Guohua used the inferior alveolar nerve transplantation technique when reconstructing Fang Guohua's left jawbone.

It's just that the intercostal nerve was transplanted along with the ribs to the left jaw area, which was done by Zhang Zifan, and he didn't pursue the surgical effect much.

After all, for Fang Guohua, it doesn't matter whether he feels the left jaw or not.

But for Kong Xiang, the perception of the hands is crucial.

Therefore, although the principles of the two operations are the same, the requirements for the degree of completion of the operation are completely different.

……

Nerves control muscles. If the nerve function is impaired for a long time, the muscles are used as target organs, and the function will also be lost.

At that point, even if nerve repair is completed, muscle function will be difficult to restore.

The doctor who performed the operation on Kong Xiang before, apparently in the spirit of seeking stability, adopted conservative treatment, but now it seems that the effect is not good.

Half a year later, the remaining window period is getting shorter and shorter, so Zhang Zifan has to take the lead and use the patient's own cutaneous nerve for nerve transplantation.

And after the [Eye of Preset] analysis, the most suitable cutaneous nerve is the sural nerve of the calf.

The sural nerve is also an important nerve in the human body, controlling the activities of the muscles of the lower limbs.

Although sural nerve injury does not affect walking, it may cause paresthesia on the lateral side of the calf and dorsum of the foot.

For a surgeon, it is absolutely willing to exchange the feeling of the calf and the back of the foot for the feeling of the hand.

Moreover, Zhang Zifan felt that if he cut off the sural nerve by three to five centimeters and then sutured the remaining sural nerve, it would not necessarily cause the loss of its function.

Because the sural nerve is longer, the anatomical potential is greater, and the relaxation can be more complete.

In short, no matter how you look at it, using the sural nerve as raw material for radial nerve transplantation is indeed an excellent surgical solution.
