As Professor Tan said early on, 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 key to success or failure of minimally invasive surgery. Based on this, we can conclude that the viewpoint proposed by Company B, based on the insights from clinical experience, should be the correct answer.
What is the basis for Sulima's repeated opposition?
The eyes of countless audience members were focused on every step of the operation on the big screen like spotlights.
Surgical scenes are sometimes boring and uninteresting because they seem to be repeating basic surgical operations such as separating tissues, cutting and stopping bleeding.
When watching an operation, an expert must concentrate and think along with the operation scene. Otherwise, he will be lost in the fog like an outsider, not knowing which part of the human body the scalpel has reached or which key step of the operation has been reached.
Different departments have different professions. Gao Zhaocheng and his colleagues in the general surgery department couldn't understand it, so they could only ask the cardiac surgery 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 blood vessel blocking band. It blocks blood vessels. You general surgeons can't have never done blood vessel blocking, right?"
“It seems to be different from what we use.”
"That's about right."
...
...
"Blocking a blood vessel? Doesn't it mean stopping the heart beating?"
"What nonsense are you talking about? This is to block the internal mammary artery. Otherwise, if the distal end of the internal mammary artery is cut, blood will spurt out."
At this point, the layman in general surgery suddenly realized and was surprised: "You're not going to take it out?"
What is it for? The internal mammary artery is close to the heart and is most conveniently connected to the coronary artery. 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 is connected to the anterior descending branch of the coronary artery to replace the blocked blood vessel segment for blood supply. At this time, doctors generally use the famous S stapler. I remember that a group of doctors had told the patient, Mr. Li, that this operation was difficult to perform. It is estimated that this patient has some special problems with his coronary arteries.
None of the preoperative examinations can compare to the direct viewing 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 big screen shifted to the patient's coronary arteries.
Some of the audience members in the audience chuckled.
In traditional cardiac surgery, the heart can be simply understood as the front and back views of the heart. The anterior descending branch, also known as the anterior interventricular branch, is mostly located in the front of the heart. It is the same as the circumflex branch and is derived from the left coronary artery trunk. 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 having three to four trunks. The circumflex branch goes around to the back of the heart, and the diagonal branches are more complicated, some are mostly in the front and some are mostly in the back.
In minimally invasive surgery, the robotic arm needs to go around the surface of the heart to make connections, instead of doing it like in traditional surgery where the doctor can just bend the heart a little to perform vascular anastomosis when the angle of the instrument cannot be lowered.
The one who made the hissing sound must be a general surgeon, because it didn't look like a cardiac surgeon had ever seen it. Even so, the cardiac surgeons present were all worried about the surgical team.
"This patient's heart may be a little twisted." said a cardiac surgeon.
This problem is not difficult to see. When the robotic arm follows a coronary artery trunk and observes its direction, the audience's vision is like riding on a small train, with a different view from time to time. In fact, it is changing the angle, which means that this trunk is not like the flat surface that most patients walk on, but mostly on a curved surface.
