The path of modern medicine is long, and doctors have come up with a variety of tools on the road to treatment. But some of the early tools were really cruel. This article counts the 7 most terrible medical devices in history, you know?
1. Artificial leeches therapeutic equipment (Artificial leeches)
The leeches live therapy is a blood-sucking therapy using starved leeches. On the one hand, the blood-sucking function of the leeches promotes blood circulation, and on the other hand, the sputum released by the leeches during the blood-sucking process has the anticoagulant function. The accumulated blood increases the perfusion of the tissue.

However, in the 19th century (1800s), the use of live water sputum therapy was ineffective or excessive bleeding, so doctors invented this kind of "water raft" equipment, which consists of metal cylinders and blades, and its rotating blades are cut into The skin, the needle sucks the blood out. There is a similar tool called the "scratch" that uses a 10 spring piece of the instrument to quickly enter the skin, which is then heated to create a vacuum.
2. Hernia tool (Hernia tool)
Since people realize that the human body can be repaired, medical repair techniques are constantly improving. In the 1950s, doctors invented a "professional tool" to treat hernia (an organ or tissue in the human body that left its normal anatomical location). Once the doctor needs to repair the tear in the muscle or tissue, they insert the tool into the site. After a week in the body, scar tissue can be formed to help seal the hernia.
