Abstract
In order to improve a surgical instrument comprising a shank and a drive shaft, which is rotatably mounted in the shank and bears or comprises a tool element at its distal end, wherein in the distal end region of the shank a radial bearing is arranged or configured for the rotatable mounting of the drive shaft on the shank, such that a reliable operation is possible even with increasing miniaturisation of the shanks, it is proposed that the radial bearing is configured in the form of a needle bearing.An improved surgical handpiece as well as an improved surgical drive system are additionally proposed.
