摘要：
A pneumatic surgical tool for cutting bone during surgical procedures includes a pneumatic motor having a rotary shaft, a resecting tool having a cutting element rotated by the motor, a sleeve to surround and support the resecting tool, anti-friction bearings for further rotatably supporting the resecting tool, and a chuck for connecting the resecting tool to a spindle of the rotary shaft. The motor housing, rotor, spindle, and chuck are created from titanium. The bore of the housing and the cutting tip of the resecting tool have thin hard metal cases, such as titanium nitride, titanium aluminum nitride, or titanium carbon nitride.
