The process of drilling holes is very common in neuro, orthopedic, and dental practices. Cannulated drill bits are one of our specialties when overcoming the issues faced while drilling bone.
Bones have poor thermal conductivity, which makes them incredibly susceptible to heat damage since they struggle to dissipate heat. Damage like this can be a significant problem and can be permanent. Known as thermal osteonecrosis, this can result when excessively high tissue temperatures are reached.
The relationship between tool geometry, drilling conditions, chip removal, and bone structure presents a challenge in developing linear mathematical models to minimize osteonecrosis in bones. Generally, heat generated due to drilling is usually caused by two main factors: the cutting edge of the tool deforming bone material or friction between the tool and surface being cut.
The temperature generated during bone drilling depends upon various parameters such as drill diameter, drill rotational speed, axial drilling forces, cooling, and more. We specialize in creating custom tools that effectively cut bones of any density or structure.
