Abstract
A self-locking spindle traction mechanism for use in surgical procedures has a longitudinal axis (L). The mechanism may include an operating end, a connecting end for connecting a surgical accessory, and a threaded spindle drive. The spindle drive may include a spindle having an external thread, and a spindle nut that is seated on the spindle and has an internal thread. The mechanism may include a slide that is movable along the longitudinal axis by a relative rotation between the spindle and the spindle nut, a drive device that is situated on the operating end for rotationally driving the threaded spindle drive, and a gear. The gear may be connected between the drive device and the threaded spindle drive, so that the gear is configured for stepping up the speed of a rotational movement of the drive device and delivering it to the threaded spindle drive.
