The stapler was not imagined out of thin air, and its development ideas must be inevitably influenced by the basic principles of manual suturing in traditional surgery.
For example, the initial stapler was linear, with points and lines like a row of staples. Later, it was changed to a ring shape and other shapes according to the shape of various human tissues to facilitate the adaptation of the anastomotic surface shape.
It should be emphasized here that the stapler was invented to solve the problem of difficulty in manual suturing by doctors, so it is not exclusive to surgeries such as thoracoscopy or surgical robots. Due to market needs, many staplers are now developed in a variety of scenarios.
, it is best to be able to meet multi-scenario applications such as traditional thoracoscopic surgery and the latest surgical robots without being constrained by the scenario.
As mentioned before, it refers to the fact that some stapler development scenarios have not been completely successful in being applied in thoracoscopes or surgical robots, making it difficult for doctors to perform such surgeries without making rice.
The S stapler used in coronary arteries that I just mentioned is becoming more and more famous precisely because many doctors who perform thoracoscopy and robotic surgeries have discovered that it is quickly becoming a necessary medical device for certain types of surgeries.
When it comes to particularly advanced features such as the S stapler, you must compare it with other types of vascular staplers. The S stapler is a coupling-type stapler, and the more popular one before it is the clamp-type stapler.
During the discussion among several geniuses at the scene, they took out the ready-made staplers and compared them on the spot, which can provide a more intuitive visual effect. It is more difficult to just think about it with your brain.
"Are there any ready-made ones here? Or did you bring them back from overseas?" Mi Wenlin saw that the things were taken out and asked Dr. Yao, the boss with a doctorate in engineering.
Yao Zhiyuan frowned.
Lin Hao looked at this junior with displeasure: What have you learned?
As the most famous cardiovascular hospital in the country, Guozhi cannot be without these world-famous specialized medical devices. Moreover, these devices are not new inventions and have been on the market for at least two or three years.
"I have never been in Guozhi before, and I have never seen a few thoracoscopic surgeries for heart surgery when I was in the cardiology department of the Chinese Association of Cardiology." Mi Wenlin defended his ignorance.
What classmate Mi said makes some sense.
As mentioned before, there are too few extracardiac total thoracic surgeries at present, and most of them adopt small incision surgery. In small incision surgery, the National Association of Cardiac Surgeons directly perform powerful manual sutures, without the unnecessary use of staplers.
One is to save some money for the patient, and the other is that the stapler must be used well and the doctor must be able to use it well. In other words, some staplers are difficult to master and not very easy to use.
"Clamp-type staplers are not very easy to use," Xie Wanying said.
The disciples looked like question marks: Why doesn't it work?
Doctors will try their best to overcome difficulties in operation for the sake of patients. The most important factors that affect the use of medical devices are the safety and effectiveness of the device. The evaluation of these two aspects should include intraoperative and long-term postoperative.
"This stapler is not very friendly to the elderly and patients with arteriosclerosis."
This problem can be traced back to the principle of the clamp-type stapler. It is to turn the end of the graft vessel over and insert it into the target vessel before performing an anastomosis. This will undoubtedly increase the tension between the graft vessel and the target vessel.
The ultimate tension of blood vessels in the elderly and patients with arteriosclerosis is low. If the stapler increases the blood vessel tension at the anastomosis of these two types of patients, it is conceivable that the anastomosis may easily leak.
