The characteristics of minimally invasive surgery, as Mr. Tan said earlier, the most important thing for doctors is to know how to make good use of the surgical instruments in their hands. This can be said to be the success or failure point of minimally invasive surgery. Based on this, it can be concluded that Company B proposed
Perspective Given insights from clinical experience, should be the correct answer.
Where did Sulima's repeated objections come from
The eyes of countless audiences are like spotlights gathering on every surgical step on the big screen.
The operation screen is sometimes very boring and boring, because it seems to keep repeating basic surgical operations such as separating tissue, incision and hemostasis. Experts have to concentrate on watching the operation, and their brains are always thinking according to the operation screen. Otherwise, it will be like a layman lost in the fog, not knowing which part of the human body the scalpel has reached, and where the surgery is.
a key step.
Every department is like a row, Gao Zhaocheng and the others couldn't understand the general surgery department, so he could only ask the cardiology department again: "What is that? Where is this? We don't use these instruments in the general surgery department."
"Don't you know? This is a blockage belt, which blocks blood vessels. It's impossible for you to have not even blocked blood vessels before, right?"
"It seems to be different from what we use."
"Roughly the same."
"Blocking blood vessels? Didn't you mean keep beating your heart?"
"What nonsense are you talking about? This is to block the internal mammary artery, otherwise, all the distal ends of the internal mammary artery will not be able to spurt blood."
Speaking of this, the layman in general surgery was stunned and surprised: "Don't take it out?"
What to do with it? It is most convenient to connect the internal mammary artery close to the heart to directly supply blood to the coronary artery, which is called in situ surgery, which is different from the great saphenous vein as mentioned at the beginning. After the internal mammary artery is treated, it will be connected to the anterior descending coronary artery to replace the blocked blood vessel segment for blood supply. At this time, ordinary doctors will use the famous S stapler. Thinking about what a group of doctors said to the patient Mr. Li before
This operation is not easy to do. It is estimated that this patient has some special problems in the coronary arteries of the heart.
There is absolutely no heart under direct vision in cardiac surgery in various preoperative examinations, so that the doctor can clearly see what the patient's heart looks like at a glance.
The perspective of the surgical field of view on the large screen has shifted to the position of the coronary artery of the patient's heart.
Some of the audience in the audience let out a chirping sound. The heart is simply understood as the front view and the back view of the heart under direct vision in traditional cardiac surgery. The anterior descending branch is also called the anterior interventricular branch. . There are often one or two diagonal branches between the two. If there are diagonal branches, it can be regarded as the left coronary artery has three to four trunks. The circumflex branch goes around the back of the heart, and the diagonal branch is more complicated. Some of the most
Most of what is in the front is in the back. Under minimally invasive surgery, the robotic arm needs to go around on the surface of the heart for connection, instead of the traditional surgery where the doctor can slightly break the position of the heart with his bare hands when the angle of the instrument cannot be adjusted.
Vascular anastomosis.
The one who made the chirping sound must have been someone from the general surgery department, because it didn't look like a cardiac surgeon. Even so, the cardiac surgery colleagues present here also have to sweat for the surgical team.
"This patient's heart may be a little twisted." The heart surgeon said. The problem is not hard to see. Seeing the robotic arm follow a coronary artery to observe its direction, the view of the audience in the audience is as if they are on a small train and change the scenery after a while. In fact, it is changing the angle, which shows that this trunk is not walking on a relatively flat plane like ordinary patients, but walking on curved surfaces more.
