  • 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.

  • Rasp determined for one-time use, particularly bone rasp as well as process for its production
    Patent number: 6120508
    Abstract: The rasp (1) has a support unit (3), which is surrounded by an envelope (4) of metal, which forms rasp teeth (5). This mode of construction permits the use of very thin sheet for envelope (4) and cost-favorable plastic for support unit (3), which makes possible the formation of a stable, well-cutting, disposable rasp.
