Chapter 3840 [3840] Different

Characteristics of Minimally Invasive Surgery As Teacher Tan said early in the morning, 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 of minimally invasive surgery. Based on this, it can be concluded that the viewpoint put forward by company B should be the correct answer in view of the insights from clinical experience.

Where did Sulima's repeated objections come from?

The eyes of countless audience members were like spotlights focused on each surgical step on the big screen.

Surgery scenes are sometimes boring and uninteresting because they seem to repeat basic surgical operations such as tissue separation, incision and hemostasis.

Experts have to concentrate when watching the operation, and their brains are always thinking according to the operation pictures. Otherwise, it will be like a layman falling into the fog, not knowing which part of the human body the scalpel has reached and which key step the operation has reached.

Gao Zhaocheng and others from the general surgery department couldn't understand it because they were separated by different departments. They could only ask the people from the cardiac surgery department again: "What is that? Where is this? We in the general surgery department don't use these instruments."

"Don't you know? This is an occluding band, which blocks blood vessels. It's impossible for you general surgeons to have never done anything to block blood vessels, right?"

"It seems different from what we use."

"Roughly the same."

"Block blood vessels? Don't you mean beating your heart?"

"What are you talking about? This is to block the internal mammary artery. Otherwise, everything distal to the internal mammary artery will not be able to spurt blood."

At this point, the layman in general surgery was suddenly surprised and asked: "Don't take it out?"

What to do with it? It is most convenient to directly connect the internal mammary artery close to the heart to supply blood to the coronary arteries. This 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 must be connected to the anterior descending branch of the coronary artery to replace the blocked blood vessel segment to supply blood. At this time, most doctors will use the famous S stapler. Recalling that a group of doctors had previously told the patient, Mr. Li, that this operation was difficult to perform, it was estimated that this patient had some special problems with his coronary arteries.

The various preoperative examinations are absolutely not like the direct view of the heart during cardiac surgery, which allows the doctor to clearly see with the naked eye what the patient's heart looks like.

The surgical field of view on the large screen shifted to the location of the patient's coronary arteries.

Some people in the audience made chirping sounds.

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, also called the anterior interventricular branch, is mostly located in the front of the heart. It comes from the main left coronary trunk together with the circumflex branch. . There are often one or two diagonal branches between them. If there are diagonal branches, it can be considered that the left coronary artery has three to four main trunks. The circumflex branch goes around to the back of the heart, and the diagonal branch is more complicated. Some are mostly in the front and some are mostly in the back.

Under minimally invasive surgery, the robotic arm needs to go around the surface of the heart to connect, unlike traditional surgery where the doctor can slightly break the position of the heart with his bare hands to perform vascular anastomosis when the angle of the instrument cannot be moved.

The person who made the chirping sound must be someone from the general surgery department, because it didn’t look like a cardiac surgeon. Even so, all the fellow cardiac surgeons here are worried about the surgical team.

"This patient's heart may be a little twisted," the cardiologist said.

This problem is not difficult to see. Seeing the robotic arm observing its direction along the main trunk of a coronary artery, the audience's vision was like riding on a small train and experiencing a change of scenery. In fact, it is changing the angle, which means that this trunk does not walk on a relatively flat surface like the average patient, but walks on a curved surface.
