YY/T 1629.5-2020Cutting tools for electric osseous tissue surgical equipment - Part 5: Saw blade (English PDF)

3.1 Saw blade

Saw blade body, connecting rod (if equipped), interface, and mechanical protection (if equipped) are composed of structural parts.

3.2 Handpiece

The formula is composed of the (power) handle that can provide power to the machine head, the machine head that clamps the tool, and (or) the speed changing mechanism and other components. [YY/T 0752-2016, definition 3.5]

3.5 Saw set

The saw teeth protrude from both sides of the saw blade body to provide saw cutting clearance.

3.7 Mechanical protection

The sheet body and other places form the required protective sheath and other structures.

Note. Except for the mechanical protection structure provided by the mobile phone.
