    The stapler is not imagined out of thin air, and its development ideas must be influenced by the basic principles of traditional surgical manual suturing.

    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 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 demand, many staplers are now

    There are many types of development scenarios, and it is best to be able to meet multiple scenario applications such as traditional surgery, thoracoscopic surgery and the latest surgical robots without being restricted by the scenario.

    What I mentioned before refers to some matchmaker development scenes to be applied to thoracoscopy or surgery robot that failed to be completely successful, making doctors doing such surgery into a clever woman with no rice.

    The S stapler that I just mentioned for use in coronary arteries 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 S staplers, you must compare them 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, taking out the ready-made staplers and comparing them on the spot 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 of the engineering doctorate.

    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 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, currently there are too few extracardiac total thoracic surgeries, and more 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.

    First, it saves the patient some money, and second, 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 showed question marks in their eyes: Why doesn¡¯t it work?

    When doctors have operational difficulties, they will try their best to overcome them 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 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. 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.  (Remember the website address: www.hlnovel.com
