"What kind of problem is not okay?" Director Fang asked several cardiac surgeons in detail because of Mr. Zhang's worrying tone.
She may have seen this type of surgery, but she is not a cardiac surgery expert and has never performed this type of operation in person, so she certainly does not have the same experience as a surgeon. Some doctors at the scene said it was OK, while some experts questioned whether it was OK. Whether it was OK or not, it may require further explanation from colleagues in cardiac surgery.
Under such circumstances, Xie Wanying was not surprised to receive a meaningful glance from two top cardiac surgery experts, Zhang Da Lao and Ren Senior Brother: "You said it's okay, you explain it to your patient friends. Anyway, we think it's not okay."
This is enough to show that this difficulty is well known and senior experts in cardiac surgery believe that it is unsolvable. Xie Wanying cannot avoid such a realistic technical problem because it does exist objectively.
"Teacher Fang, as Director Zhang said, some parts of the human body are very difficult for doctors to sew up manually. This is determined by the special anatomical structure of certain parts of human tissue." Xie Wanying said, "What Director Zhang wants to say is that it is precisely for this reason that it is difficult to perform full thoracoscopic surgery on four-vessel lesions."
"Would it be better to use a surgical robot? I heard that it can magnify the surgical field much more than a thoracoscope." Director Fang asked again, obviously trying his best to fight for the patient's last hope.
"This question is not about whether or not we can see the surgical field clearly." Xie Wanying said.
To be precise, it is the feel. It is much more difficult for doctors to suture with long-distance tools than with short tools. As mentioned earlier, the slow or missing transmission of sensory information by long-distance tools will lead to a serious lack of feel in the doctor's operation. What's more, it is difficult for doctors to sew well even with sufficient feel, let alone suturing without the doctor's feel.
"How do we solve this problem?" Director Fang was troubled after hearing this. What he didn't understand was that she had just said that it was something that could be considered, but according to the current statement, wouldn't it be hopeless?

"Teacher Fang, you know that you have seen many surgical operations and you know that the progress of medical technology is the result of a comprehensive combination of many aspects. It is difficult to achieve the overall surgical goal by relying on the development of only one technology. In addition to expanding the doctor's surgical field of view, endoscopic surgery must also solve the technical difficulties of other operations of the doctor, otherwise it will be useless."
"I understand." As expected of a big shot, Director Fang understood immediately, "You are talking about the stapler."
The doctor uses a stapler to help with places that are difficult to sew manually. Not to mention endoscopic surgery, there are also many cases of using staplers to solve such difficult surgeries in traditional surgery.
Laparoscopic surgery is more assisted by staplers than traditional surgery due to the lack of hand feeling. It can be said that some places must need staplers to solve the problem. For example, the thoracoscopic surgery for single lesion that is being discussed now greatly improves the success rate of the surgery because of the use of staplers. The TECAB demonstrated by Company B also uses staplers.
Here comes another question. There are various types of anastomosis devices, and they are not universal. The vascular anastomosis device used for single-vessel lesions must be specially developed for this type of surgery, and can be used to connect the internal mammary artery and the left anterior descending artery. The implication is that if you want to perform laparoscopic surgery on four-vessel lesions, a more sophisticated vascular anastomosis device has not yet been invented.
