Abstract
A measuring device for bone screw types of different shaft diameters is described. This measuring device has multiple receiving grooves for bone screws in a surface or an area near the surface. In the area of each receiving groove a length measuring scale, which is associated with one or more of the different bone screw types, is arranged. Also, for each of the receiving grooves a limit stop to work with a received bone screw is provided. The receiving grooves and/or the associated limit stops have a selectivity with respect to the shaft diameter of the bone screw types which can be received in the individual receiving grooves.
Claims11
A measuring device for bone screws having different shaft diameters, comprising:
- a body having a surface and an edge with a face running essentially vertically to the surface at the edge;
- multiple receiving grooves defined in the surface for receiving the bone screws, each of the receiving grooves having an open end in the face of the body at the edge of the body;
- a length measuring scale defined at each of the receiving grooves for measuring the bone screws;
- and
- a limit stop associated with each of the receiving grooves for cooperating with a received bone screw, each limit stop including two limiting elements projecting upwardly from the surface and defining a channel between the two limiting elements extending downwardly below the surface, the two limiting elements having a spacing between each other that defines a selectivity with respect to the shaft diameter of the bone screw which can be measured in the associated receiving groove,
- wherein the limit stops are arranged in the region of the face at the edge of the body to form part of the face.
