Knapp Needle-Knife

The Knapp needle knife is an innovative instrument developed by German surgeon and physicist Hermann Knapp (1891-1962) in 1932. It was created to simplify breast surgery and had no analogues at that time. Since then, Knappa began developing other tools, including forceps for ligating veins when opening veins, as well as an electrocautery machine and an electric drill.

Despite their sophisticated design and technical advantages over older surgical methods, Knap needle-knives were still considered not very reliable in operation. Studies have shown that if used incorrectly, this instrument could rupture a patient's lung or other internal organs. Also, its use was limited and extended only to chest surgery, since Knapp was not the best surgeon in the field of cardiovascular surgery. But despite all the shortcomings, surgeons still use some of Knapp's instruments, such as forceps for ligating veins and two types of needles for the heart and mitral valve.

Having created this instrument using an electric drill and power tools, Knapp also developed a variety of techniques for performing procedures in the field of breathing and the circulatory system. These techniques have helped reduce the number of complications after surgery, reduce the risks of surgery and increase the effectiveness of treatment. Today, in a modern world where many types of medical procedures are performed on a robot, the idea of ​​the technology created by Knapp is still relevant.
