CHIRURGISCHE SÄGE

摘要

A surgical saw has a sector-shaped saw blade (11) mounted on a shaft (10). The shaft (10) is surrounded by a coaxial second shaft (14) to which an eccentric member (15) is mounted close to the saw blade (11) and parallel therewith. Both shafts (10,14) and thus the eccentric member (15) and the cutting blade (11) can be rotated with respect to each other and can be fixed in their rotational position. Depending on the rotational position, the saw blade (11) is either covered by the eccentric member (15) in a rest position to be inserted in a hollow bone, or is indexed in a position to be freely and gradually exposed to make a sawing operation possible.
