Abstract
A bone incision block includes an incision guide, a localization reference adjustably attached to the incision guide, a fastener for fastening to a bone, and an adjustment device. The incision guide defines an incision plane, and the localization reference enables the incision plane to be spatially determined. The adjustment device is operatively coupled between the fastener and the incision guide, wherein the incision plane can be set relative to the bone via the adjustment device, and a spatial position of the adjustment device can be determined via a registration element.
Claims21
A bone incision block, comprising:
- an incision guide that defines an incision plane;
- a localization reference adjustably attached to the incision guide, said localization reference enabling the incision plane to be spatially determined;
- a fastener for fastening to a bone;
- and
- an adjustment device operatively coupled between the fastener and the incision guide, wherein the incision plane can be set relative to the bone via the adjustment device, and a spatial position of the adjustment device can be determined via a registration element.
A method for user guidance in setting an incision plane defined by an incision guide of a bone incision block using an incision guide adjustment device, comprising:
- defining a target incision plane;
- spatially determining an actual incision plane with the aid of a medical navigation system and a localization reference adjustably attached to the incision guide;
- determining the spatial position of the adjustment device via a registration element;
- and
- outputting adjustment instructions based on the spatial position of the adjustment device, which, starting from the actual incision plane, assist the user in setting the target incision plane.
