Chapter 1386： 2 kinds

"The hepatic portal is blocked, a 15-minute countdown." Ling Ran gave an order, and the nurses inside and outside the operating room immediately adjusted the time.

Liang Xue took a deep breath and concentrated his energy at the same time.

The most difficult part of liver surgery lies in the rich blood supply in the liver, and the bleeding caused by knife-cutting needle drills is difficult to control. Modern medicine is very different from early Western medicine in that the amount of bleeding must be controlled throughout the operation, rather than in the early stages. Like the barbaric medicine in China, if he is quick to go, he will do a trick of amputation in a few seconds and then stop the bleeding.

However, compared with other organs of the human body, the liver is particularly fragile and important. After the blood supply to the liver is blocked, the probability of failure after the operation is completed and reperfusion is very high. Therefore, the early clinicians Created the "low temperature anesthesia", the principle is a bit similar to the cardiopulmonary bypass, using low temperature to reduce the body's resistance, which can block the blood flow for a longer period of time.

However, the damage in this way is also great, and it will especially cause considerable pain to the patient. Therefore, when Wu Mengchao proposed the "intermittent hepatic portal block and hepatectomy method at room temperature", it will attract world-class attention. .

What Ling Ran uses today is the traditional "hepatectomy with intermittent hepatic portal blockage at room temperature." First of all, without hypothermic anesthesia, the patient's pain will be reduced and the prognosis will be better. Secondly, intermittently blocking the hepatic portal, that is, intermittently supplying blood to the liver, can ensure the liver's activity to the greatest extent, and this time was also determined by Wu Mengchao using experimental dogs and several attempts.

Blocking the hepatic portal blood supply for 15 minutes and releasing it for 5 minutes can greatly reduce the proportion of patients with acute liver failure after surgery, and at the same time reduce the occurrence of liver ischemia reperfusion injury, thereby improving the safety and success rate of surgery . This model used to be the "magic weapon" of Chinese liver surgery. In those days, there were tactics that could be used to "shock" foreigners at any time.

Of course, after repeated shocks, its promotion in the world was so fast that it soon became one of the standard procedures in international liver surgery.

However, no matter how good the solution is, it can only reduce the damage, and it is impossible to achieve no damage.

Therefore, during the 15-minute hepatic portal block time, the surgeon needs to work hard. In this 15-minute and 15-minute cycle, the fewer cycles there are, the less damage to the patient’s body will naturally be.

From this perspective, the speed of surgery has become a very important indicator.

The reason why modern surgical instruments and equipment are updated so quickly, in addition to the addition of medical capitalization, is an extremely important reason for the harshness of new technologies and new discoveries.

The same surgeon uses traditional surgical scalpels and needles to perform operations. The cutting and stitching speed must be much slower than that of the doctor who uses the electric knife. Similarly, the speed of the surgeon who uses the ultrasonic knife must be the same level. The best among doctors.

The mechanical arm of the Da Vinci robot synthesizes a large number of functions, and it is said that it also has the function of increasing the speed, but in actual use, the operation space greatly limits the doctor's performance.

No matter how large the pneumoperitoneum can be created, the operating space cannot be compared with the open surgery. The 720-degree maneuver of the robot arm can only make up for it when doing the dojo in the shell of the snail. Therefore, the total length of surgery performed by the Da Vinci robot may be longer than that, and the corresponding fineness has been improved.

At this time, what the doctor can do is to concentrate on using technology to bridge the technological gap.

Liang Xue had a solemn expression, using what he had learned throughout his life to follow Ling Ran's operations.

He is a doctor from Dapu. It is reluctant to say that he is a first-class domestic doctor in terms of liver technology. However, his position as an assistant is very powerful. His understanding of the anatomical relationship in the abdominal cavity, the mastery of various advanced theories, the experience of problems in clinical surgery, and his prior familiarity with the Da Vinci robot belong to the assistant. This position can play a role, but it is completely unnecessary. Such extravagant skills.

Because of this, Liang Xue also lay down on the console with confidence, cooperating with Ling Ran's operations.

Originally very simple operation.

In fact, it is very simple. From the beginning of the operation to the blocking of the first hepatic portal, Liang Xue cooperated very easily, and when the first hepatic portal was blocked, Liang Xue was even more confident and calm.

Then, Ling Ran shouted "Attention" again.

Liang Xue smiled and paid attention, and then...

He suddenly questioned the joystick of the Da Vinci robot.

"Why can't you keep up?" Liang Xue muttered in his heart, and hurriedly cheered for Ling Ran's operation, but he still felt a little slow.

Ling Ran, who had accumulated more than 10 operations, had already completely surpassed his proficiency in controlling the Da Vinci robot at this time.

And when he can control the machine perfectly, his perfect liver resection skills become extremely powerful.

It is even more different from open surgery, because the manipulator of the Da Vinci robot can rotate 720 degrees, so when the surgeon actually rotates the manipulator, it has a huge ability to imagine the space of the doctor. test.

If you want to describe it, normal surgeons use Da Vinci as if they are flying a civil aviation plane. Although the plane can rotate clockwise and counterclockwise, they usually don't do it. Even a doctor with a bit wild driving will ensure the range of rotation as much as possible.

Ling Ran's operations today looked like a crazy fighter pilot.

When needed, the manipulator under his control rotates almost all the time.

Spin.

Constantly rotating.

Liang Xue felt that he did not vomit, UU reading is already a gift of the body.

"Count down 10 seconds." Lu Wenbin in the operating room reminded.

Ling Ran seemed to have not heard, still operating frantically.

"5, 4, 3..." Lu Wenbin's reminder also continued.

Ling Ran released the hepatic portal block at the last moment.

"The countdown is 5 minutes." Lu Wenbin started timing again.

Ling Ran raised his head at this time, looked at the console on the left, and asked, "How do you feel."

Director Liang Xue looked up and smiled reluctantly: "No problem."

Facing the doctors in and out of the room, Liang Xue still raised his chest, showing a calm expression, but his heart roared like a typhoon: "Why don't the machines I use and those used by Ling Ran look the same? "
