Controlled local tissue removal device with medical removal tool has rotation axis about which tool can move on closed trajectory laterally separate from axis, which always intersects working region

摘要

The tissue removal device has a medical removal tool (1) with a material removing working region and that can be guided relative to a tissue region (2) to remove material and form a blind hole in the tissue region. A rotation axis is provided about which the tool can be moved along a closed trajectory laterally separate from the axis, which always intersects the material removing working region.
