The stapler is not imagined out of thin air, and its development ideas must be influenced by the basic principles of traditional surgical manual suture.
For example, the stapler at the beginning was linear, and a few points lined up like a row of staples. Later, according to the shape of various human tissues, it was changed to a ring shape and other shapes to facilitate the adaptation of the anastomotic port 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 thoracoscopy or surgical robots. Due to the needs of the market, many types of stapler development scenarios are now available. It is best to meet the multi-scenario applications such as traditional thoracoscopic surgery and the latest surgical robots without being bound by the scene.
What I mentioned before means that some stapler development scenarios that want to be applied to thoracoscopic or surgical robots have not been completely successful, making it difficult for doctors to perform such operations.
The s-stapler used in coronary arteries just mentioned is becoming more and more famous, precisely because many doctors find that it is quickly becoming a necessary medical device for certain types of surgery when performing thoracoscopic and robotic surgery.
When it comes to particularly advanced features such as the s stapler, it must be compared with other types of vascular staplers. The s stapler is a coupled stapler, and the more popular one before it is the clamped stapler.
When several geniuses were discussing at the scene, they took out the ready-made staplers and compared them on the spot, which could have a more intuitive visual effect, and it was more difficult to think with the brain alone.
"Is there any ready-made one here? Or did you bring it back from overseas?" Seeing that the things were brought out, Mi Wenlin asked Dr. Yao, a doctor of engineering.
Yao Zhiyuan frowned.
Lin Hao looked at this junior with displeasure: What have you learned?
Guozhi, as the most famous cardiovascular hospital in the country, cannot have these world-renowned specialized medical devices. Moreover, these devices are not new inventions, and have at least two or three years of market history.
"I was not in Guozhi before, and I didn't see many thoracoscopic surgeries on the heart when I was in the Department of Cardiac Surgery of the National Association of China." Mi Wenlin defended his ignorance.
Student Mi's words make sense.
As mentioned above, at present, there are too few extracardiac total thoracic surgeries, and most of them use small incisions. In the small incision surgery, the heart surgeons of the National Association of China directly start the powerful manual sewing work, and there is no need to use a stapler.
One is to save some money for the patient, and the other is to use the stapler 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.
"The clamp-type stapler is not easy to use." Xie Wanying said.
The apprentices showed question marks in their eyes: Why is it not easy to use?
The doctor will try his best to overcome the difficulty in operation for the patient. The most important factor affecting the unusability of medical devices is the safety and use effect of the device. The evaluation of the 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 for anastomosis, which 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 vascular sclerosis is low. If the stapler increases the tension of blood vessels at the anastomosis in these two types of patients, it is conceivable that the anastomotic leakage will easily occur.
