The stapler was not imagined out of thin air; its development ideas must have been influenced by the basic principles of traditional surgical manual suturing.
For example, the initial stapler was linear, with a few points and a line like a row of staples. Later, it was changed to other shapes such as rings according to the shapes of various human tissues to facilitate the adaptation of the anastomotic surface.
It should be emphasized here that the invention of the stapler is to solve the problem of manual suturing by doctors, so it is not exclusive to thoracoscopic or surgical robot surgeries. Due to market needs, many staplers are now developed in a variety of scenarios, preferably to meet the needs of traditional thoracoscopic surgery and the latest surgical robots and other multi-scenario applications without being restricted by the scenario.
What was mentioned before is that some stapler development scenarios that were intended to be used in thoracoscopy or surgical robots have not been completely successful, making it difficult for doctors to perform such operations.
The S stapler just mentioned for coronary artery use is becoming more and more famous because many doctors performing thoracoscopic and robotic surgeries have found that it is almost becoming an essential medical device for certain types of surgery.
When talking about the advanced features of the S stapler, we must compare it with other types of vascular staplers. The S stapler is a coupling type stapler, and the more popular one before it was the clamp-closed stapler.
When several talented people were discussing on the spot, they took out ready-made staplers for comparison, which could provide a more intuitive visual effect. It would be difficult to think about it with just the brain.
"Is there anything ready here? Or did you bring it back from overseas?" Mi Wenlin asked Dr. Yao, a PhD in Engineering, when he saw the things being taken out.
Yao Zhiyuan frowned.

Lin Hao looked at this junior with displeasure: What have you learned?
As the most famous cardiovascular hospital in China, it is impossible for Guozhi to not have these world-renowned specialized medical devices. Moreover, these devices are not newly invented and have a history of at least two to three years on the market.
"I had never been to Guozhi before, and I had never seen many laparoscopic heart surgeries during my internship at the National Association for Cardiac Surgery." Mi Wenlin defended his ignorance.
What Mr. Mi said makes some sense.
As mentioned earlier, currently there are too few full-thorax surgeries outside the heart, and most of them are small-incision surgeries. In small-incision surgeries, the Chinese cardiac surgeons directly perform the powerful manual suturing work without the unnecessary use of staplers.
First, it can save patients some money, and second, the good use of staplers requires doctors to have the ability to use them. In other words, some staplers are difficult to master and not very easy to use.
"The clamp-type stapler is not very easy to use." Xie Wanying said.
The disciples looked at him in question: Why doesn’t it work?
Doctors will try their best to overcome difficulties in operation for the sake of patients. The most important factors affecting the poor use of medical devices are the safety and effectiveness of the devices. The evaluation of these two aspects should include intraoperative and long-term postoperative evaluation.
"This type of stapler is not very friendly to the elderly and patients with vascular sclerosis."
This problem can be traced back to the principle of the clamp-type anastomosis device, which is to turn the end of the transplanted blood vessel over and insert it into the target blood vessel for anastomosis, which will undoubtedly increase the tension between the transplanted blood vessel and the target blood vessel.
The ultimate tension of blood vessels in the elderly and patients with vascular sclerosis is low. The stapler increases the vascular tension at the anastomosis of these two types of patients, which can easily cause leakage at the anastomosis.
