Abstract
A medical instrument for dilating osseous structures, with a shaft on whose distal end a tool point is positioned and on whose proximal end a handle is positioned, such that the handle and the tool point are in active connection with one another by means of an actuating element in such a way that by actuating the handle the tool point can spread radially at least partially and where the distal end of the actuating element has a thickened configuration. To provide a dilating instrument that is sufficiently stable and allows for sensitive actuation, it is proposed with the invention that the tool point should consist of several segments that can radiate radially outward and enclose the thickened distal end of the actuating element essentially completely, when the tool point is in the closed position.
