1. A cutting device for placement of a knee prosthesis comprising:
a bracket being comprised of a first marker, a mast having a longitudinally extended portion, and a bracket fixing element, said first marker having a first rectangular plane surface so as to form a first pattern corresponding to location of said bracket, said bracket fixing element being configured to attach to a bone;
a cutting guide being movably mounted on said bracket and
being comprised of
a second marker and
a slot, said second marker having a second rectangular plane surface so as to form a second pattern corresponding to location of said cutting guide,
wherein said slot defines a cutting plane so as to guide a cutting tool,
wherein said cutting guide is movable mounted on said bracket in at least one translational degree of freedom, and
wherein said cutting guide is movably mounted on said bracket according to at least two degrees of freedom in rotation; and
an articulated assembly received on said mast and connected to said cutting guide so as to move said cutting guide relative to said bracket,
wherein said articulated assembly comprises:
a first control means for rotation along a first axis;
a second control means for rotation along a second axis; and
a third control means for translation along a third axis,
wherein the first control means comprises:
a first screw;
a first movable element on said first screw; and
a first drive element being in pivoted engagement with said first movable element and being connected to said cutting guide so as to rotate said cutting guide according to rotation of said first screw by said first moveable element,
wherein the second control means comprises:
a second screw;
a drive wheel on said second screw; and
a slope pivot being in threaded engagement with said second screw and being connected to said cutting guide so as to rotate said cutting guide according to rotation of said second screw by said drive wheel,
wherein the third control means comprises:
a carriage in sliding engagement with said mast so as to move said articulated assembly and said cutting guide along said third axis.
