Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
80 words
A device (10; 30; 70; 90; 110) for positioning a cutting guide (100) with respect to a bone (14) comprising: a body (16; 112) forming the cutting guide or intended to be fixed to the cutting guide; a least two contact members (26A-26E; 36; 72; 94A-94D; 114A, 114B, 122) intended to freely contact the bone; and adjustment means (24; 34; 80; 92; 118A, 118B; 120) for individually varying the relative position of the body with respect to each contact member.
Claim 2
Dependent Claim
31 words
The device of claim 1, wherein each contact member (26A-26E; 36; 72; 94A-94D; 114A, 114B, 122) is linked to the body (16; 112) according to a one degree of freedom connection.
Claim 3
Dependent Claim
28 words
The device of claim 1, comprising a further contact member (40) intended to freely contact the bone, the further contact member being fixed with respect to the body.
Claim 4
Dependent Claim
45 words
The device of claim 1, wherein at least one contact member is a screw (26A-26E; 36; 94A-94D; 122), the tip of which being intended to freely contact the bone (14), the body (16; 112) including a threaded hole (24; 34; 92; 120) receiving the screw.
Claim 5
Dependent Claim

The device of claim 1, wherein at least one contact member (72; 114A, 114B) includes a curved portion (78).
Claim 6
Dependent Claim
42 words
The device of claim 1, wherein the body (16) includes means for guiding a cutting tool with respect to at least one cutting plane, and wherein the contact members (26A-26E; 36; 72; 94A-94D; 114A, 114B, 122) do not cross the cutting plane.
Claim 7
Dependent Claim
77 words
A system for assisting a surgeon in cutting portions of a bone (14), comprising: a device (10; 30; 70; 90; 110) for positioning a cutting guide (100) according to claim 1; means for determining a theoretical position of said device relative to the bone; localization means for determining an actual position of said device relative to the bone; and means for providing data (62, 64) representative of the difference between the actual position and the theoretical position.
Claim 8
Dependent Claim
33 words
The system according to claim 7, comprising means for displaying an image (62) representative of said device at the actual position, and an image (64) representative of said device at the theoretical position.
Claim 9
Dependent Claim
37 words
The system according to claim 7, comprising means for measuring the position of each contact member (26A-26E; 36; 72; 94A-94D; 114A, 114B, 122) relative to the body (16; 112) of said device (10; 30; 70; 90; 110).
