Technology is always changing, especially when it comes to medicine. Researchers and scientists are constantly developing new ways to combat severe illnesses and everyday health issues. And as history will tell you, these devices have become crucial in determining how certain diseases are diagnosed. None of these devices are used anymore and thankfully so, as many of these procedures were done without the help of anesthesia. As you can imagine, patients suffered great physical traumas and were sometimes permanently maimed after doctors used them.

It was used in the 1500s to do exactly what its name implies — extract bullets. Doctors would inset the metal head into a person’s body and then the middle part would be lengthened to pierce the bullet. The doctor would then pull the entire instrument out of the patient’s body. These types of instruments only achieved popularity as firearms became more and more sophisticated, The Independent reported.
