Step-by-step explanation:
A rongeur is a surgical instrument used by doctors during various medical procedures. This tool is specifically designed to remove small pieces of bone or other hard tissue. It is commonly used by neurosurgeons, orthopedic surgeons, and oral surgeons. The rongeur is designed to create a clean cut or to nibble away at the tissue with its sharp-edged, scoop-like tip. It provides precision and control in tight spaces, which is essential during intricate surgeries. One common application of the rongeur is in spinal operations where surgeons may need to remove small bone fragments or shave down areas of bone to relieve pressure on nerves.
