A common example of a surgical rongeur is the Kerrison rongeur, in which its first design was created by Dr. Robert Masters Kerrison (1776–1847), an English physician, but it took more than 100 years before the Kerrison rongeur was modified and took its current form.
The Kerrison rongeur is often cited as a prime example of a surgical instrument, initially designed by Dr. Robert Masters Kerrison, an English physician, in the late 18th century. Nevertheless, it wasn't until over a century had elapsed that the design underwent significant transformations to yield the modern version.
