摘要:
A hand instrument, comprising: a tool-holding device for fastening a treatment tool on the hand instrument, a driveshaft for transmitting a driving movement to the tool-holding device and a stroke gear which is designed to induce the tool-holding device in a stroke movement. According to a first embodiment the hand instrument further has a rotary gear which is designed to induce the tool-holding device to a rotational movement, wherein a drive-side element of the rotary gear and a drive-side element of the stroke gear are arranged jointly on the driveshaft. According to a second embodiment the drive-side element of the stroke gear is designed such, that in a complete revolution of the drive-side element of the stroke gear the tool-holding device runs through more than a double stroke. According to another embodiment the drive-side element of the stroke gear is disposed concentrically around an axis of rotation of the driveshaft.
