Abstract

The invention relates to a surgical instrument with an instrument handle, an instrument shank connected to the instrument handle, an instrument tip with a work point, which instrument tip is connected to the instrument shank, and a first locator arranged on the instrument handle or the instrument shank. During a use of the surgical instrument, the instrument shank can be deflected, e.g. on account of transverse forces, at least between the first locator and the work point. A second locator is arranged at a distance from the first locator and, by comparison with the latter, closer to the work point, wherein the second locator is designed to detect five degrees of freedom.
