Device for aligning a guide template
First Claim
1. A device for aligning a surgical instrument in connection with one compartment knee-joint replacements, comprising:
- A) first and second support members (12;
5), said first support member having a first support surface (3) and said second support member having a second support surface (6), each of said support surfaces (3;
6) being adapted to bear against one condyle (24;
25) of a femur (21);
B) at least one rod-like transverse coupler (10;
11) arranged parallel to a transverse axis (2) that intersects both condyles (24;
25), said at least one rod-like transverse coupler having an end portion that is connected to the first support member (12) and releasably connectable to the second support member (5), wherein the transverse axis (2) extends parallel to a plane (1); and
C) at least one guide template (20), the guide template (20) being displaceable parallel to the plane (1) relative to the second support member (5) and releasably lockable thereon via a positioning means (26); and
wherein D) the second support member (5) is secured against rotation about the transverse axis (2) while being displaceable coaxially with the transverse axis (2) on the at least one transverse coupler (10;
12) and releasably lockable thereon.

Abstract
A device for aligning a guide template used in resecting a distal femur in a one-compartment joint replacement. The device includes first and second support members (12;5), at least one rod-like transverse coupler (10;12), and a guide template (20). The support members each include a support surface (3;6) that is adjustable to lie in one plane (1) and designed to bear against one condyle (24;25) of a femur (21). The transverse coupler is arranged parallel to a transverse axis (2), which, in its end portion, is connected to the first support member (12) and is releasably connectable to the second support member (5). The transverse axis (2) extends parallel to a plane (1). The guide template (20) is displaceable parallel to the plane (1) relative to the second support member (5) and releasably lockable thereon. The second support member (5) is secured against rotation about the transverse axis (2) while being displaceable coaxially with the transverse axis (2) on the at least one transverse coupler (10;12), and is releasably lockable on the transverse coupler.
