Abstract
Abstract A slide bed device for mounting an orthopedic bone cutting device so as to provide a surgeon with three accurately controlled degrees of freedom of movement of the cutter thereby facilitating extremely accurate placement of the saw preparatory to making in vivo bone cuts. The cutting device (25) is slidably mounted (20) on a vertical stand (18) for movement in a vertical plane, and the vertical stand (18) is in turn mounted perpendicularly on two relatively movable horizontal slides (15,17) at right angles to each other. The horizontal slides (15,17) are mounted on a three point frame (6,11,12) arranged for rigid adjustable mounting on the bone to be cut in a plane parallel the longitudinal axis of the bone.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
217 words
A device for mounting an orthopedic bone cutting device so as to facilitate accurate in vivo bone cuts, characterized by: (a) frame means (2) including attachment means (6, 11, 12) for adjustably mounting said frame on a bone to be cut; (b) first slide bed means (14) mounted on said frame in a first plane substantially parallel the longitudinal axis of said bone; (c) first slide means (15) mounted in said first slide bed for reciprocal longitudinal movement therealong; (d) second slide bed means (16) mounted on said first slide means; (e) second slide means (17) mounted on said second slide bed means for reciprocal longitudinal movement, in a second plane parallel said longitudinal axis of said bone, and perpendicular to the direction of movement of said first slide means; (f) stand means (18) mounted on said second slide means in a plane-perpendicular thereto and parallel the longitudinal axis of said first slide means; (g) third slide means (20) mounted on said stand means for reciprocal longitudinal movement therealong in a plane perpendicular said first and second planes; and (h) means (26) to releasably secure said cutting device (25) to said third slide means so that a cutting edge (28) thereof may be moved into cutting engagement with said bone at a selected position and angle thereto.
Claim 2
Independent Claim
217 words
A device for mounting an orthopedic bone cutting device so as to facilitate accurate in vivo bone cuts, characterized by: (a) frame means (2) including attachment means (6, 11, 12) for adjustably mounting said frame on a bone to be cut; (b) first slide bed means (14) mounted on said frame in a first plane substantially parallel the longitudinal axis of said bone; (c) first slide means (15) mounted in said first slide bed for reciprocal longitudinal movement therealong; (d) second slide bed means (16) mounted on said first slide means; (e) second slide means (17) mounted on said second slide bed means for reciprocal longitudinal movement, in a second plane parallel said longitudinal axis of said bone, and perpendicular to the direction of movement of said first slide means; (f) stand means (18) mounted on said second slide means in a plane-perpendicular thereto and parallel the longitudinal axis of said first slide means; (g) third slide means (20) mounted on said stand means for reciprocal longitudinal movement therealong in a plane perpendicular said first and second planes; and (h) means (26) to releasably secure said cutting device (25) to said third slide means so that a cutting edge (28) thereof may be moved into cutting engagement with said bone at a selected position and angle thereto.
Claim 3
Dependent Claim
57 words
A device as claimed in claim 1 characterized in that said attachment means comprises first pin means (6) for insertion into said bone perpendicular the longitudinal axis thereof and second and third pin means (11, 12) for insertion into respective opposite sides of said bone in a plane perpendicular to said first pin means and remote therefrom.
Claim 4
Dependent Claim
28 words
A device as claimed in claim 2 characterized in that adjusting means (8) are provided on said first pin means for adjusting said frame relative to said bone.
Claim 5
Dependent Claim
24 words
A device as claimed in claim 1, 2 or 3 characterized in that said cutting edge (28) comprises a segmental laterally oscillating saw blade.
