"Scalpel."

Qin Feng didn't pause at all, took the scalpel and cut the skin of the toe directly.

"Cut the blood flow and perform nerve anastomosis." Qin Feng said.

The movement of human palms is controlled by nerves, and nerves belong to the soul of fingers. Qin Feng just shaped the flesh of fingers.

Taking the place where the nerve needs to be sutured as the center, Qin Feng dissociates directly from the proximal side of the nerve stump to the part where the nerve is connected on the other side. This step is to leave a sufficient surgical field for himself.

Compared with skin suturing for skin trauma, the effect of nerve suturing has a lot to do with the surgical field, and generally two to three incisions are required.

"Xiao Qin, how are you going to suture?" Director Zhang asked curiously.

"Interrupted stitching." Qin Feng said.

"Why? Isn't continuous suture better?" Director Zhang asked puzzled.

Qin Feng kept moving his hands and explained: "Continuous overlock suture is not suitable for nerve suture. Once there is an inappropriate suture or the nerve excitement point is too high, the entire nerve will be pulled by the suture, resulting in distortion. .Once the nerves are twisted, the nerves are damaged, as is the neurological damage to the muscles in a cauda equina."

Cauda equina neurological injury is mainly a neurological syndrome in which the peripheral nerves are exposed to external factors, resulting in paralysis, disorder or dysfunction around the nerves, and even the inability to regulate movement and sensation in the area dominated by the nerves.

This syndrome, in different cases, also has different consequences.

Generally speaking, paraplegia will occur if the nerve is ischemic for too long, or if secondary edema and paralysis worsens. Damage to some cauda equina nerves is a man’s nightmare, not only causing paralysis of the lower body, but also causing lower body function. obstacle.

This kind of neurological injury is a world-class medical problem. There is no solution yet, and Qin Feng naturally will not have a solution.

In dealing with this aspect, everyone tries to avoid cauda equina nerve damage as much as possible. One of the most important causes of cauda equina nerve damage is nerve distortion.

It is not to say that a nerve twist is a cauda equina injury, but a cauda equina injury must have a nerve twist.

For the success of this operation, Qin Feng naturally avoids risks if he can.

Director Zhang also nodded seriously after listening. Naturally, he knew the consequences of nerve damage.

Qin Feng lowered his head and continued to mobilize the nerves on the severed surface and toes under micromanipulation, and at the same time remove the diseased nerves.

Within the scope of medicine, as long as it is diseased, it cannot be left behind, no matter how important it is.

After removing the diseased nerves, Qin Feng discovered a more serious problem, that is, several nerves suffered from nerve shortage, that is, they were a little short and could not be connected to the designated parts.

Fortunately, the patient's joints can be lowered to allow it to flex under Ali, and Qin Feng stretches the nerve to extend it to the normal range.

"Director Zhang, help me stabilize my nerves," Qin Feng said.

Director Zhang is now fully substituted into the position of assistant, and Qin Feng does whatever he says, which makes him feel strange.

Qin Feng tried to perform joint bending and anastomosis, because the sutures between the nerves should not have tension. Once there is tension, the sutured wound will burst and cause secondary damage.

Therefore, when Qin Feng stretched the extension nerve before, it was slightly extended by 0.1 mm. The extra point was to avoid accidents and prevent problems before they happen.

With the nerve stitched up, the operation went well and there were no issues.

Director Zhang looked a little silly.

"That's awesome, isn't this suture method really done by a young doctor?"

"Is this still a double anastomosis? The nerve transplant was directly selected from the diseased nerve, and the nearby nerves were also pulled over and anastomosed."

The previous scenes have refreshed Director Zhang's views, and Qin Feng's status in his heart is also constantly rising.

Thinking about the treatment given to Qin Feng by the Second Court, I thought it was inappropriate before, but now it seems that the Second Court has taken advantage of it, even if the treatment is doubled, it is worth it.

Qin Feng didn't notice Director Zhang's gaze, but directly put down the needle forceps and breathed a sigh of relief, after all, the operation was over.

The blood vessels and nerves are very small, about the size of a hair, and interventional methods cannot be used, only manual methods can be used.

This kind of suturing and reconstruction consumes a lot of energy for the doctor, and it is still late at night.

"Director Zhang, I will leave the cross stitching of muscles and tendons to you," Qin Feng said.

This kind of suture is charged, it is the same as closing the abdomen in open surgery, whether you want Qin Feng or not is the same.

Qin Feng also wanted to take a rest. After a high-intensity operation, doctors would feel tired.

It's just that Qin Feng didn't leave, but watched Director Zhang operate.

Different muscles in the human body have different connection methods. For example, the diameter of both ends of the tendon is similar, so it can be sutured directly. If the tension is relatively large, a steel wire needs to be inserted into the tendon, and the suture is performed with the help of the steel wire. Qin Feng left it long ago. A cut was made just for this step.

This incision can reduce injuries, and at the same time, Qin Feng's incision not only exposed the nerve, but also provided a good surgical field for the current muscle suturing.

Since muscle is subcutaneous tissue, absorbable threads are generally used.

"Xiao Qin, help me tighten the two ends of the tendon."

Qin Feng nodded, took the hemostat directly to clamp the ends of the tendons on both sides, tightened them and anastomosed them together.

There is no need to ensure that there is no tension when dividing the tendons, because the tension itself is very high. Just like any movement of our palms, it will cause the contraction of the palm muscles. The sutures need to be relatively strong, so that they can Avoid surprises.

This kind of suture is relatively simple for Qin Feng, but it is also a challenge for Director Zhang.

Because the muscles are changing at any time, just like a dead fish that has been disemboweled and will jump twice.

Fortunately, there were no major problems, and the operation went smoothly.

Director Zhang also had a higher evaluation of Qin Feng. In fact, Qin Feng could do the tendon suture just now, but he let himself do it.

Ordinary doctors may feel that they are testing themselves, but Director Zhang knows that once this operation is publicized, all the medical staff involved in the operation will benefit a lot.

Especially for a doctor who has used a knife, that is even more terrible, and his reputation can soar to the sky.

"Director Zhang, you are not good at tying a knot." Qin Feng stepped forward and re-tie the knot and press it into the surface of the tendon.

Many people know that when suturing, the most likely to break is not the suture, but the knot left after the suture is completed.

Man-made knots cannot be tougher than seamless sutures anyway, and the muscle tissue itself is the most active part, and the tension in the tendon is the smallest. If you want to protect the knots, the best choice is to tie the knots Burying into the surface of the tendon reduces tension.
