Answer: Saggital saw.
Explanation:
A saggital saw is a specialised saw used by orthopedic surgeons in bone resection. The blade of a saggital saw oscillates through a small angel, this helps to prevent causing damage to surrounding tissue, this results in the reduction of cutting rate due to short stroke length. A saggital saw oscillates at 10,000- 20,000 per minutes. Saggital bone saw with orbital blade motion is aimed at improving efficiency in cutting.
