Chapter 3758 【3758】Nothing Can Be Done without Rice

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 or other shapes according to the shape of various human tissues to facilitate the adaptation of the anastomotic surface.

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 the needs of the market, many staplers are now developed in a variety of scenarios. It is best to be able to meet multiple scenarios such as traditional surgery, thoracoscopic surgery and the latest surgical robots without being restricted by the scenario.

As mentioned before, it refers to the fact that some stapler development scenarios that want to be applied in thoracoscopy or surgical robots have not been completely successful, making it difficult for doctors to perform such surgeries.

The S stapler used in coronary arteries that I just mentioned is becoming more and more famous precisely because many doctors who perform thoracoscopic 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. The more popular stapler before it was 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 would give a more intuitive visual effect. It was more difficult to think about it with just their brains.

"Are there any ready-made ones here? Or did you bring them back from overseas?" Mi Wenlin asked Dr. Yao, the boss of the engineering doctorate, 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 the country, Guozhi cannot be without these world-famous specialized medical equipment. Moreover, these devices are not new inventions and have been on the market for at least two or three years.

"I have never been to Guozhi before, and I have never seen a few thoracoscopic surgeries for heart surgery when I was a trainee at the Cardiac Surgery Department of the Chinese Association." Mi Wenlin defended his ignorance.

What classmate Mi said made some sense.

As mentioned before, currently there are too few extracardiac total thoracic surgeries, and most are performed through small incisions. During the small incision surgery, the National Association of Cardiac Surgeons directly performed powerful manual suturing work, without the unnecessary use of staplers.

One is to save the patient some money, 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 easy to use." Xie Wanying said.

The disciples looked like question marks: Why doesn't it work?

Doctors will try their best to overcome operational difficulties for the sake of patients. The most important factors that affect the poor 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 vascular sclerosis."

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 for 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.
