Abstract
In a saw for surgical purposes comprising a saw blade holder movable by a motor and a saw blade fixable in the saw blade holder, to enable insertion and removal of the saw blade without a tool, it is proposed that the saw blade holder comprise an insert guide for the saw blade with a holdback projection, that the saw blade carry a resilient detent projection which in a relaxed position, with the saw blade inserted in the insert guide, engages the holdback projection from behind, and that an actuating element be mounted on the saw blade holder for displacement against the resilient detent projection, the actuating element moving the resilient detent projection, during the insertion, into a tensioned position in which the detent projection is pushable past the holdback projection when the saw blade is pulled out of the saw blade guide.
