On June 10, we visited the museum of the history of medicine to see the evolution of medical and health tools used for medical practice over the years. As seen above, one of the tools for neurosurgery used is a drill for creating holes- burr holes- in the skull as part of the initial process of neurosurgery. The name contains “Trépan” which translates to “drill” and the previous part means head. Today, after years of tool development we have electric drills to make burr holes making it much easier and safer because of stainless steel, high precision, and lesser chance of infection.
