Chapter 221： Weaving (1/2)

Suturing blood vessels is a very familiar task for Ling Ran.

When he first arrived in Yunhua, the medical administration department used sutured rats' tails to dismount.

Now that I want to come, it is equivalent to let the recruits and special forces compete in sniper shooting, the difficulty is already in the top of the industry.

However, suture the vascular network is still a difficult challenge beyond the normal level.

The blood vessels in the foot are thicker than those in the hand. That is the main arteriovenous vein. The perforating branch artery shunted from the posterior tibial artery or peroneal artery is not so wild. Many of them are thinner than the arteries of the fingers.

The suturing of suturing fingers is only two or three, three or four.

Of course, the actual difficulty is still more difficult than suturing the fingers. Because broken finger sutures have extremely high requirements for the quality of sutures of blood vessels, and the tolerance for low-quality sutures is very low. A bad one is thrombotic necrosis.

The vascular network around the Achilles tendon does not have such high requirements. Academician Zhu Tongyi's plan a, that is, the reconstruction of the vascular network. There are three or four perforating arteries on the inner side of the Achilles tendon and three or four perforating arteries on the outside of the Achilles tendon. Claim.

The most important thing is that even if Ling Ran fails to suture one or two blood vessels, it will not cause too much impact, at least it will not cause Achilles tendon suture failure.

As for the failure of the original plan, for such an experimental operation, there will be many statements of success. If it fails, there is no way to explain it.

Zhu Tongyi stared at Ling Ran's movement quietly, seeming more nervous than Ling Ran.

Ling Ran's operation is more and more relaxed.

I saw that his wrist was soft, and his fingers lightly slid under the microscope. A few times, he sutured a blood vessel, then scooped out another blood vessel, brushed it a few times, and stitched it again.

Ji Tianlu was busy cooperating, and even the second assistant Lu Wenbin kept moving around the operating table, moistened the blood vessels with saline, moistened the gauze, sucked for a while, and pulled the hook for a while. Status.

Everyone frowned, with a **** battlefield, staying up late to make up for the pain of homework.

Only Ling Ran, apparently immutable, flew up in his heart.

This is how to sew blood vessels to living people, and it can sew one net at a time. How cool is this?

If a broken finger is replanted, Ling Ran must first perform debridement carefully, then fix the bones, and then suture the tendon, and then have the opportunity to play with the most critical two or three blood vessels. After playing, stitch the nerves and throw the sutures to other animals.

In Ling Ran ’s sense, debridement is not so interesting anymore. The internal fixation of bones is more like a carpenter's job. If the tendon is sutured, the flexor tendon is still fun. The ordinary tendon is not good enough. The most interesting part of replantation.

Today, what kind of scene did Ling Ran encounter?

Large vascular network, and small and difficult vascular suture.

It is equivalent to taking out the best part of the replantation of broken fingers for Ling Ran to play.

Ling Ran's mood, let alone how happy he is.

This is not the rat tail in the exercise room. Perhaps for newcomers, being able to sew rats once is already very happy, however, Ling Ran has already passed that newcomer stage.

There is a living person who can sew, and it has the cooperation of one help and two help. There are equipment nurses to deliver things, and there are sew-up nurses to help sew. It is more comfortable than sitting alone in the practice room alone.

”Change a little more suture.” Ling Ran was happy, and sutured three perforating arteries in one breath. Facing the thinner fourth one, he changed the thread again.

Academician Zhu Tongyi had to remind him, ”Your key is to pay attention to dynamic balance.”

The implication is that he cannot resew the entire vascular network, and can only choose important blood vessels to form a barely usable vascular network.

This is like after a war, the original meticulous and orderly logistics lines were destroyed by most of the generals responsible for reconstruction. The task of the generals responsible for the reconstruction is not to restore each original logistics line a little bit, but to focus on restoring one. The supply chain is to ensure the supply of the most important materials, and the rest of the supply chain can be completely restored to other people for a longer period of time.

Ling Ran understood the order of Zhu Tongyi very well. He nodded and explained, ”I want to make an extra path out.”

Unlike ordinary ”generals”, Ling Ran is in good shape. He doesn't just want to restore a supply chain, he wants to make one more.

”Are there enough time?” Zhu Tongyi looked up at his watch, his expression relaxed a little.

Ordinary Achilles tendon surgery takes about an hour or two. The time on the operating table is two hours long and 30 to 40 minutes short.

Zhu Tongyi's plan a is more complicated. He plans to give the surgeon four hours of surgery. This time is not casually spoken, but a ”dynamic balance” made according to the degree of Achilles tendon exposure and so on.

The time is too short for the main knife to complete the operation. If the time is too long, the effect of the operation may be compromised.
