What is the name of the instrument shown below and what is the function of it?
Rongeurs - Forceps with heavy cupped tips that cut bone. Use for debriding bone, removing thin chips of bone and smoothing of rough edges. The double action gives mechanical advantage allowing more pressure to be applied (thicker bone)
What is the name of the instrument that is shown below?
Bone-cutting forceps - used for the sharp cutting of bone but is an inprecise cut. The double action allows for more leverage
What is the name of the tools shown below and what is the function of them?
Osteotomes and chisels:
- Osteotomes have a bevel on both sides of the cutting edge and are manipulated with minimal drift
- Chisels have a bevel on one side only and may drift away from the beveled edge when being used
