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.
Claims18
A measuring device for bone screw types of different shaft diameters, the measuring device having a surface and comprising
- multiple receiving grooves for bone screws, the receiving grooves being located in the surface or a portion near the surface, each receiving groove being associated with a limit stop to cooperate with a received bone screw and with a length measuring scale for one or more of the different bone screw types, at least one of the receiving grooves and the associated limit stops having a selectivity with respect to the shaft diameter of the bone screws which can be received in the individual receiving grooves.
A measuring system comprising
- multiple bone screw types;
- and
- multiple receiving grooves for bone screws, the receiving grooves being located in the surface or a portion near the surface, each receiving groove being associated with a limit stop to cooperate with a received bone screw and a length measuring scale for one or more of the different bone screw types, at least one of the receiving grooves and the associated limit stops having a selectivity with respect to the shaft diameter of the bone screws which can be received in the individual receiving grooves.
A device for measuring the length of bone screws having different screw shaft diameters, comprising
- a surface;
- multiple receiving grooves for bone screws located in the surface or at least partially under the surface, each receiving groove being associated with a length measuring scale for determining the length of one or more bone screw types, each receiving groove further having a stop for cooperating with a received bone screw, wherein at least one of the receiving grooves and the stops associated with the receiving grooves have a selectivity with respect to the shaft diameter of the bone screws that can be inserted in the individual receiving grooves.
