Abstract

A screwdriver for introducing and screwing a screw into the human or animal body and/or for unscrewing and removing a screw from the human or animal body has a handle and a shaft whose front end has a blade that can be brought into engagement with a screw head of the screw for screwing the screw. The screwdriver furthermore has a retention device for retaining the screw on the blade. The retention device has an inner tubular shaft which surrounds the shaft and has at the distal end a clamping gripper preloaded into its open position, and an outer tubular shaft surrounding the inner tubular shaft. Arranged on the handle is an actuation device for the inner tubular shaft and outer tubular shaft that is movable from a first position into a second position, as a result of which the opened clamping gripper is displaced over the blade out of a pulled-back position, and the actuation device being movable out of the second position into a third position, as a result of which the outer tubular shaft is displaced relative to the inner tubular shaft over the clamping gripper in order to close the latter, and vice versa.
