Chapter 526 Super microscopic technology, venous stent!

The paper was spread out, and everyone's attention was immediately diverted.

After seeing the title, Director Yu and others were slightly stunned.

"Application of Super Microsurgery Combined with Improved Venous Microscopic Stent in Replantation of Broken Finger"

"This..."

Yue Pan, the director of hand surgery who came specially to review the paper, was surprised.

Strictly speaking, it was not a review, but a worship.

In front of Noah, only Xu Qiu dared to say the word "review", and the others were far inferior.

Yue Pan took the paper, and the others got up from their seats, gathered in front, and admired it carefully.

Although they knew little about hand surgery, they could also see the value of this paper.

"Super microsurgery is a concept proposed by Professor Koshima, the chairman of the World Reconstructive Microsurgery Society..." Yue Pan's hands trembled with excitement.

Daxia has always been at the forefront of the world in the field of replantation of broken fingers, but in the new era, with the development and emergence of various technical forces, various fancy technologies and skills have come to the stage, and this discipline has also been pushed into the era of competing in science and technology.

The super microsurgery technology proposed by the country can perfectly solve the problem of "unable to anastomose small blood vessels and single nerve bundles".

Moreover, it is very effective for tissue replantation technology with a blood vessel diameter less than 0.3mm.

Xu Qiu's palm and finger regeneration surgery, in which the tip of the finger is replanted, belongs to the category of blood vessels with a diameter less than 0.3mm, but Xu Qiu used a method of one force to defeat ten skills, and mastered the fingertip replantation with an operation difficulty that is almost impossible to replicate.

Later, Xu Qiu continued to improve in the simulated operating room, repeatedly reducing the difficulty and improving the skills, and finally taught the regeneration technique with a reduced difficulty to others...

And this super micro technology solves the problem of the inability to anastomose tiny blood vessels in another clever way.

Before this, a lot of research was conducted in China, but it was unsuccessful.

However, Noah's paper revealed this secret!

More importantly, Noah also proposed the concept and structure of the microscopic stent for replantation of broken fingers!

Yue Pan was attracted by it.

This finger replantation micro-stent consists of a bridge segment and an anastomosis segment at both ends of the bridge segment.

Among them, the wall of the anastomosis segment gradually thickens from the end away from the bridge segment to the other segment, forming a conical outer surface; while the outer surface of the bridge segment is concave inward, and the remaining anastomosis segments form an anchoring area.

The anchoring area also has a special design.

For example, the anchoring needle.

This is used to pierce the blood vessel wall and fill it with anchoring paint to achieve the purpose of anchoring.

"This micro-stent can also be used in palm and finger regeneration! Its appearance can effectively provide circumferential support for the vascular anastomosis point, greatly shortening the operation time and further reducing the difficulty of the operation!" Yue Pan was so excited that he couldn't help himself.

The blood vessels of the fingers are extremely thin, especially the fingertips. The blood vessels here are distributed with the center of the finger web thread as the dividing line, spreading out in a branched shape, and the thinnest part is even less than 0.1mm.

Therefore, the surgeon must anastomose the extremely thin blood vessels less than 0.3mm or even less than 0.1mm under a microscope.

Moreover, it is not enough to just suture successfully. The anastomosed blood vessels must be able to circulate blood smoothly, and there must be no exposed thread ends to avoid thrombosis, infection, etc., which is as difficult as climbing to the sky.

One of the difficulties is that the blood vessels are too small, and they will be sunken if they are touched slightly.

But how can the blood vessels not be touched during the suture process?

Because the blood vessels are too small, there is no room for error, and the arteries and veins that can be found in the finger replantation surgery are extremely limited, and those that meet the conditions for anastomosis and blood supply are even more scarce.

Any failure is very likely to be the failure of the entire operation!

However, the emergence of venous micro-stents has solved this problem!

With the help of stents, blood vessels can be stretched in a ring and will no longer collapse due to pressure; and anchoring needles further increase the speed of the operation. The operator can complete the operation in a shorter time than before, improve fault tolerance, surgical success rate, postoperative functional recovery, and reduce risks!

"Not only that, Professor Noah also gave us a modified antegrade replantation method!"

Yue Pan didn't see anything at first, but as the paper progressed, Noah elaborated on the characteristics of this method in detail, and he suddenly realized it and was amazed.

The conventional antegrade replantation method is debridement-bone fixation-flexor and extensor tendons-dorsal veins of the fingers-dorsal skin of the fingers-digital arteries-digital nerves-palmar skin of the fingers.

But Noah made a subtle change.

The anastomosis of the subcutaneous vein was placed behind the fixed bone.

This step directly changed the previous horizontal position of the affected finger to an upright position, with the palmar wound edge as the turning axis, and turned the broken finger to the palmar side, and approached from the dorsal wound, so that the proximal section and the distal section were exposed upward, so that the surgeon's surgical field of the wound surface changed from the previous squint to a direct view!

It's like looking at people with squint eyes and looking at people straight!

This undoubtedly completed a better exposure of the surgical field and made the surgeon's operation smoother.

"Whether it is the microscopic stent or the improved antegrade method, they are both important papers that can influence hand surgery. If they are released, they will cause major medical journals to scramble for them!" Yue Pan gave the final evaluation.

Director Yu's tense expression eased a little: "Professor Noah is an honest person."

The others also showed comfortable expressions.

It's good to have Xu Qiu here. The big guys have sent papers to him one after another. If Linhai Dayi doesn't become a core journal, who can?

Even the top medical journals in China are not qualified to allow Noah, Joseph, Saito and others to submit papers!

"Let's take a look at Professor Joseph's!" Director Yu was a little impatient.

Professor Noah has produced papers of this level. If you fail to do so, we will look down on your status as a living fossil of cardiac surgery...

Yue Pan put down Noah's paper with some reluctance and looked at another one.

This time, it was Director Zheng who came to review.

Although Director Yu is a paper expert, he is in the field of orthopedics. He could provide some guidance on Xu Qiu's bone reconstruction at the beginning. He could say a few words about the papers of internal doctors of Linyi, regardless of the department, but he was completely unqualified when facing Noah and Joseph.

He could only shout 666 like he did when he saw Xu Qiu's paper.

"There are three papers in cardiac surgery..." Director Zheng was also a little itchy.

Seeing Yue Pan's reaction, he could feel that the papers of Joseph, Saito and another famous foreign doctor would not be too bad!

"Joseph came from the Cleveland Clinic, which is a temple for cardiac surgeons and the world's top technology holy land and surgical base for cardiac surgery... Many of the high-difficulty surgeries in the hospital were performed by Joseph!

"Moreover, he is different from Noah!

"Noah retired to the second line almost ten years ago and put more energy into scientific research. But Joseph has always been active on the operating table, and his papers are more meaningful to clinicians!"
