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 point of minimally invasive surgery. Based on this, it is concluded that Company B
The views presented should be the correct answers given the insights from clinical experience.
Where did Sulima's repeated objections come from?
The eyes of countless audience members were like spotlights focusing 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 must concentrate when watching a surgery, and their brains should always follow the operation pictures. Otherwise, it will be like a layman falling into a 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 the differences between departments, so they could only ask 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 not even do vascular blocking, right?"
"It seems different from what we use."
"Roughly the same."
"Block the blood vessels? Don't you mean to keep beating the heart?"
"What are you talking about? This is blocking 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 processed, it needs to be connected to the anterior descending branch of the coronary artery to replace the blocked blood vessel segment for blood supply. At this time, ordinary doctors will use the famous S stapler. I thought that a group of doctors had said this to the patient Mr. Li before.
The operation is difficult to perform. It is estimated that this patient has some special problems with the coronary arteries of his heart.
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 heart 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, and together with the circumflex branch, it comes from the main left coronary trunk.
.There are often one or two diagonal branches emerging from between the two. If there are diagonal branches, it can be regarded as 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
The branches are 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 noise must have been someone from the general surgery department, because it was not like a cardiac surgeon who had seen it. 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. When you see the robotic arm observing its direction along a coronary trunk, the audience's vision is like riding on a small train and changing the scenery for a while. In fact, it is changing the angle, indicating that this trunk is not
Generally speaking, patients walk on relatively flat surfaces, but they walk more on curved surfaces.
