Device for defining a cutting plane for a bone resection
First Claim
1. A device for adjustable definition of a cutting plane for a bone resection, the device comprising:
- a base body that is adapted to be positionable on the bone; and
a cut-guiding body which is mounted so as to be variable in position on the base body; and
wherein the cut-guiding body has a cut-guiding structure for guiding a cutting tool in the cutting plane, wherein the cut-guiding body is tiltable relative to the base body by a first adjustable tilt mechanism about at least a first axis in order to adjust an angle of the cutting plane;
wherein the first tilt mechanism has;
a first linear guide arranged on a first element of the cut-guiding body; and
a first slide which is linearly displaceable along the first linear guide in the longitudinal direction thereof, and wherein the first tilt mechanism also has a second element of the cut-guiding body tiltable relative to the first element about the first axis,a first guide section opposite to a second guide section upon which the first slide moves with an active portion during the displacement, wherein interacting structures are formed in the first guide section and in the active portion and form a slotted guide which acts transversely with respect to the longitudinal direction; and
wherein the device further comprises;
a first guide groove in the first guide section, wherein the first guide groove is curved with respect to the longitudinal direction; and
a guide pin engaging in the first guide groove and guided therein on the active portion of the first slide.

Abstract
An adjustable device for defining a cutting plane for bone resection comprising a base positionable on the bone and a cut-guiding element placeable on the base. The cut-guiding element includes a cut-guiding structure for guiding a cutting tool in the cutting plane, the cut-guiding element being tiltable relative to the base about at least one first axis by an adjustable tilt mechanism to adjust the angle of the cutting plane. The tilt mechanism includes a rectilinear guide and a slide that is linearly displaceable along the guide in the longitudinal direction. The tilt mechanism includes a guide portion relative to which an effective portion of the slide is displaced; the guide portion and the effective portion having interacting structures forming a sliding guide effective at a right angle to the longitudinal direction.
