Chapter 1386 Two kinds
"Hepatic portal blockade, fifteen minutes 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 focused his energy at the same time.
The most difficult part of liver surgery is that the liver has a rich blood flow, and the bleeding caused by knife cutting and needle drilling is difficult to control. The big difference between modern medicine and early Western medicine is that the amount of bleeding must be controlled throughout the operation, and it cannot be like the early barbaric medicine, with a quick way and a trick of amputating the limb for several seconds and stopping the bleeding at any time.
However, compared with other organs in the human body, the liver is particularly fragile and important. After blocking the blood supply of the liver, the probability of failure is very high after the surgery is completed. Therefore, early clinicians created the "low-temperature anesthesia method". The principle is a bit similar to the external circulation of the heart. It uses a low-temperature method to reduce the body's resistance, thereby blocking blood flow for a longer time.
However, this method of damage is also extremely great, especially causing considerable pain to the patient. Therefore, when Wu Mengchao proposed the "intermittent liver portal blockade and liver cleavage method at room temperature", it attracted world-class attention.
Ling Ran today uses the traditional "intermittent liver hilar blocking and liver cleavage method at room temperature". First, without hypothermia, the patient's pain will be reduced and the prognosis will improve. Secondly, intermittent blocking of the liver hilar, that is, intermittent blood supply to the liver, can ensure the activity of the liver to the greatest extent. This time was determined by Wu Mengchao's experiment dog and tried it many times.
Blocking blood supply to the liver hilar duct for 15 minutes and loosening for 5 minutes can greatly reduce the proportion of acute liver failure after surgery, and also reduce the occurrence of liver ischemia and reperfusion damage, thereby improving the safety and success rate of the surgery. This model was once the "magic weapon" of Chinese liver surgery. In that era, tricks that could "shock" foreigners at any time.
Of course, after repeated shocks, its promotion internationally was so fast that it quickly became one of the standard procedures for international liver surgery.
However, no matter how good the solution is, it can only reduce the damage and cannot be damaged without damage.
Therefore, during the 15-minute liver portal blockade time, the surgeon needs to do his best. In this 15-minute and 15-minute cycle, the fewer the cycles, the less the damage to the patient's body will naturally be.
From this perspective, fast surgery has become a very important indicator.
Why modern surgical instruments and equipment are updated so quickly? In addition to the addition of medical capitalization, new technologies and new discoveries are extremely important reasons for the harshness of time.
The same surgeon uses traditional surgical scalpels and needlework to perform surgery, and the speed of cutting and suture must be much slower than that of doctors using electric knife. Similarly, the speed of surgeons using ultrasound knife is definitely the best among doctors of the same level.
The robotic arm of the Da Vinci robot has synthesized a large number of functions, which are also capable of increasing speed, but in actual use, the surgical space greatly limits the performance of the doctor.
No matter how large the pneumophila that can be made, the surgical space cannot be compared with open surgery. The 720-degree rotation of the robot arm is only a way to make up for it when doing a dojo in the snail lion shell. Therefore, the total duration of the Da Vinci robot for surgery may be exceeded, and the corresponding improvement in precision is achieved.
At this time, all doctors can do is to concentrate on using technology to make up for the technical gap.
Liang Xue looked solemn and used what he had learned throughout his life to operate according to Ling Ran's operations.
He is a doctor from the general public. He is a bit of a top-notch doctor in the country. However, he is very good at being an assistant in this position. His understanding of the anatomical relationship in the abdominal cavity, his mastery of various advanced theories, his experience in clinical surgery, and his familiarity with the Da Vinci robots are all part of the assistant position that can play a role, but there is no need for such luxurious skills at all.
Liang Xue was therefore confidently lying on the console and cooperating with Ling Ran's operation.
It was a very simple operation.
The reality is also very simple. From the beginning of the operation until the first liver portal is blocked, Liang Xue cooperates easily. When the first liver portal is blocked, Liang Xue is even more confident and calm.
Then, Ling Ran shouted "Attention".
Liang Xue smiled and paid attention, and then...
He suddenly had questions about the joystick of the Leonard of the Leonardo da Vinci robot.
"Why can't keep up?" Liang Xue murmured in his heart, and quickly started to do it, but he always felt a little slower.
Ling Ran, who had accumulated more than 10 surgeries, had completely exceeded his proficiency at this time.
And when he was able to perfectly control the machine, his perfect liver resection skill became extremely powerful.
What is even more different from open surgery is that because the robotic hand of the Da Vinci robot can rotate 720 degrees, when the surgeon really rotates the robot, it is a huge test for the doctor's spatial imagination.
If you want to describe it, a normal surgeon uses Da Vinci, just like driving a civil aviation aircraft. Although the aircraft can rotate clockwise and counterclockwise, they usually do not do this. Even a doctor with a wilder driving force will ensure the rotation range as much as possible.
Ling Ran’s operation today is like a crazy fighter pilot.
When needed, the robot he controlled was spinning almost all the time.
Rotate.
Constantly rotating.
Liang Xue felt that it was already a gift from his body that he had not vomited.
"Count down to 10 seconds." Lu Wenbin in the operating room reminded.
Ling Ran still operated frantically as if he hadn't heard it.
"5,4,3..." Lu Wenbin's reminder also continued.
Ling Ran released the liver gate block at the last moment.
"Countdown to 5 minutes." Lu Wenbin started the 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 forced a smile: "No problem."
