  • Percussive tool, in particular for surgical use
    Patent number: 7637327
    Abstract: The invention relates to a percussive tool having an oscillatory drive (3), the force of which is transmitted to a tool bit holder (25) by way of a drive member (17). Extending through the percussive tool is a longitudinal opening that allows a rod-shaped object, such as, for example, a guide wire, to be guided through the percussive tool. The tool bit holder (25) has a seat (34), which can receive the tool bit in different orientations. Moreover, the tool bit holder (25) is made of a combination of light metal and steel, which allows a reduction in acceleration forces and noise generation. A saddle-shaped coupling (24) is provided between the tool bit holder (25) and the drive member (17), which guarantees a tight fit.
