The system takes me for surgery

The operation to be performed this time is an extrathoracic combined lobectomy, which is a surgical option for early-stage non-small cell lung cancer.

Due to the difficulty of this operation and the special background of the characters, Liang Yi and Lu Chenhao not only fully analyzed the scope and nature of the patient's lesions, but also performed blood and urine routine tests, liver and kidney functions, coagulation mechanism, and cardiopulmonary function tests. A comprehensive investigation was carried out.

This time, the patient's position is also very special. The patient is lying on the healthy side, and the operating table is in the "jackknife position" at 30°.

In this position, the upper limb on the operated side is suspended on the anesthesia head frame, and the operator operates on the side of the patient.

This operation requires positive pressure ventilation of the affected lung after resection of the lung lobe, so that the residual lung can be fully inflated to avoid localized atelectasis that is difficult to identify under thoracoscopic examination.

Even the choice of incision in this operation is very complicated. There are three options for surgical incision.

One is a thoracoscopic incision, which is generally chosen between the anterior midline of the eighth intercostal space.The choice of incision location varies slightly from patient to patient and the lobe to be resected.

In the second type of operation trocar incision, 1 to 2 trocar incisions are generally used, and sometimes 3 trocar incisions are used; their positions can be determined after thoracoscopic exploration of the thoracic cavity, and the principle is to facilitate the operation.The operating hole of the retractor is generally selected near the posterior axillary line between the seventh and eighth intercostals.

The third type of small incision on the chest wall. The location of the small incision is generally selected between the anteroposterior and axillary lines in the fifth intercostal space. In addition, it can be selected according to the needs of the operation and the resection of different lung lobes.The selection of small incisions should generally follow the principle of being close to the hilum, less damage to the chest wall, and relatively minimally invasive incision scars.

After careful planning, Liang Yi and Lu Chenhao found that the small incision on the chest wall is difficult, but the damage is small, and it is more suitable for patients with many underlying diseases.

The management of the hilar vessels and bronchi is complex and requires anatomical lobectomy.

Lu Chenhao said, "This side, I'll come first."

Liang Yi nodded.

Lu Chenhao chose lobectomy without retracting the ribs and large hilar stapling. Under thoracoscopic display, the hilum was dissected sharply and bluntly.

Use the lung grasping forceps to lift the lung lobe to be resected, and then use a rubber catheter to bypass the hilum. The catheter is drawn out from a chest wall incision. The catheter is removed, the stuck needle is pushed down, the stapler is fired, and the hilum is stapled.

Liang Yi admired it very much, this is indeed a master-level operation.

Lu Chenhao took out the stapler, reinstalled the staple clip, sent it into the chest cavity through the incision, stuck the hilum again at the distal end of the first staple, and fired the stapler.Cut the lung lobe from the distal end of the stapler, put it in a specimen bag, and take it out through a small incision.

The thoracoscopic operation was very exhausting. After a while, Lu Chenhao was sweating profusely and was a little tired. This is why he said that he could not complete the operation alone, because it was only a third of the time after the operation, and he was already a little tired. Weakened and dizzy.

Li Zhengping's surgery team, who is the second-tier emergency director, and Xu Bowen's surgery team from the general surgery department are on standby outside.

When Li Zhengping saw Liang Yi as Lu Chenhao's assistant, he had a very good understanding, pointing to where to shoot, and whatever field of vision Lu Chenhao wanted, he could immediately aim. Liang Yi's skills are quite comprehensive, did not expect thoracoscopy to be so good?"

Xu Bowen was also very surprised, and said: "Yes, I thought he was just doing a good job as a test shopkeeper, but I didn't expect that he is also very good as a thoracoscopy assistant."

Qin Hanyun watched silently from the side, and secretly sighed psychologically, as expected, high-level system users are really omnipotent, as if they can learn anything as soon as they get started.

"This surgery doesn't look easy. It's really amazing that Lu Chenhao can do it so smoothly." Li Zhengping said.

Xu Bowen said: "That's right, this operation is very difficult, and there are tumors in both lungs, it is not a small operation. Lu Chenhao has no shortcomings other than being a little lazy."

"Director Xu hit the point in one sentence."

The operation on one side is completed, and the other side will be operated on next.

Liang Yi recommended himself: "Brother Hao, let me come to the other side."

"No problem?" Lu Chenhao said.

"No problem, don't worry." Liang Yi nodded in response.

Li Zhengping asked: "This is how Lu Chenhao is going to come down, does Liang Yi mean to go up?"

Xu Bowen looked at it and said, "It's really like this."

"Has he had this operation before?"

"I don't know if I asked him."

Qin Hanyun thought to herself, in reality, it is estimated that there is no such operation opportunity, but in the system, Liang Yi estimated that this operation has been performed tens of times.

After knowing that the situation had changed, Ouyang Pingan saw the freshly washed white coat in the nurse's aunt's duty room, and put on a student's white coat and mixed it into the surgery demonstration classroom. He thought badly, is he going to reveal his secrets now?

Unexpectedly, Qin Hanyun was concentrating on watching the projection screen and didn't see himself at all. Ouyang Pingan was relieved. He thought that as soon as he saw the OK gesture, someone would be there immediately, and it is not suitable to stay here for a long time.

When operating the thoracoscope, Liang Yi stretched out his hand and made an OK gesture. He didn't know if Ouyang Ping'an had seen this gesture, but this was the "signal" gesture they said during the last handover. A dead horse can be a living horse doctor.

After seeing the gesture, Ouyang Pingan knew that the action could start, and he immediately left the demonstration room, ready to start action.

Under the thoracoscopic display, Liang Yi held the atraumatic endoscopic grasper with one hand to lift the adventitia of the vessel, and the other hand held the endoscope stripping hook to separate the adventitia of the vessel, and bluntly dissected the vessel. Cut off the pulmonary vessels with an endoscopic vascular suture cutter through a small incision in the chest wall under direct vision.

Lu Chenhao kept looking at the monitor, nodding from time to time, but didn't speak, because Liang Yi's operation was very proficient, and his movements and positions were very precise, there was nothing to remind him.

In order to reduce pulmonary congestion and blood oozing from the lung section, Liang Yi treated the pulmonary artery and post-processed the pulmonary vein.

On the other side, according to the original plan, Ouyang Pingan opened all the backup hacking scripts in the computer. He first used the simplest and rude distributed denial of service (DDoS) attack.

This is one of the methods of network attack. Its principle is to use a large number of legitimate requests to occupy a large amount of network resources to achieve paralysis of the network. Hackers attack the target through a large number of controlled computers at the same time, exhausting the server's CPU and network bandwidth. , memory and database services, etc., in order to achieve the purpose of affecting the normal use of users.
