"What kind of problem is it?" Boss Zhang's tone was worrying, and Director Fang asked several cardiac surgeons in detail.
Speaking of which, she may have seen this kind of surgery, but she is not a cardiac surgery expert and has never done this kind of operation herself, so she definitely does not have the experience of a surgeon in this area. Some doctors at the scene said it was OK, while others questioned whether it was OK. Whether it was OK or not may require further explanation from fellow cardiac surgeons.
Under this situation, Xie Wanying unexpectedly received meaningful glances from two top cardiac surgery experts, Mr. Zhang and Mr. Ren: You said yes, you can explain it to the patient's friends. Anyway, we don’t think it’s possible.
It is enough to show that this difficulty is well known and senior experts in cardiac surgery believe that it cannot be solved. She, Xie Wanying, cannot avoid such practical technical problems, because objectively they do exist.
"Teacher Fang, as Director Zhang said, some parts of the human body are very difficult for doctors to sew by hand. This is determined by the special anatomical structure of certain parts of the human body." Xie Wanying said, "Director Zhang What I want to say is that it is for this reason that it is difficult to perform thoracoscopy surgery for four-vessel lesions under total thoracoscopy."
"Is it 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 to give the patient the last hope.
"This question is not a one-sided question of whether one can see clearly the surgical field." Xie Wanying said.
It's the feel, to be exact. It is much more difficult for a doctor to suture with a long-distance tool than with a short tool. As mentioned before, long-distance tools transmit sensory information slowly or missing, resulting in a serious lack of feel for the doctor's operation. What's more, it is difficult for doctors to suture this area with sufficient touch, let alone without a doctor's touch.
"How to solve this problem?" Director Fang became confused after hearing this. What he didn't understand was that what she just said was something that could be considered. According to the current statement, wouldn't it be hopeless?
"Teacher Fang, you know that you have seen many surgical operations and know that the progress of medical technology is the result of multiple aspects. It is difficult to achieve the overall surgical goal by relying on one technical development alone. In addition to expanding the doctor's surgical field of view, endoscopic surgery must , the technical difficulties of other operations for doctors must be solved at the same time, otherwise it will be useless.”
"I understand." As expected of a boss, Director Fang understood immediately, "You are talking about the stapler."
A stapler is used to assist the doctor in areas that are difficult to sew manually. Not to mention endoscopic surgery, there are also many surgical cases in which staplers are used to solve such difficulties in traditional surgery.
In laparoscopic surgery, due to the problem of lack of hand feel, staplers are used to assist more than traditional surgeries. It can be said that in some places, staplers are definitely needed to solve problems. For example, in the thoracoscopic surgery to treat single-vessel disease that is being discussed now, the success rate of the surgery has been greatly improved because of the use of staplers. The TECAB demonstrated by Company B also used a stapler.
Here comes another question. There are various types of staplers and they are not universal. The vascular stapler used for single-vessel lesions must have been specially developed for this type of endoscopic surgery, and is a special model designed to connect the internal mammary artery and the left anterior descending artery. The implication is that if surgery for four-vessel lesions requires the assistance of a vascular stapler, it has not yet been invented.
