Surgical cutting block

Claim 2

A cutting guide to guide a cutting blade for cutting bone to receive a component of a prosthesis comprising a body having at least one stationary, relatively flat guiding surface, a movable plate having a relatively flat surface which is substantially parallel to said stationary guiding surface, means to move the movable plate towards and away from the stationary surface to create a space between the stationary guiding surface and the surface of the movable plate to receive a cutting blade and to maintain the cutting blade against the stationary surface.

Claim 3

The cutting guide of claim 1 further comprising means to maintain the guide in a fixed position on the bone structure to be cut.

Claim 4

The cutting guide of claim 1 further comprising a handle affixed to that part of the guide which contains the stationary guiding surface.

Claim 5

The cutting guide of claim 1 further comprising at least two stationary guiding surfaces and at least two movable plates to provide two different spaces to receive a cutting blade.

Claim 6

The cutting guide of claim 1 in which the movable plates are secured to a bar, said bar having teeth along a portion of its length, a pinion in contact with the teeth on said bar so that the rotation of the pinion will move the bar and the plates attached to the bar.

Claim 7

The cutting guide of claim 5 in which the pinion is at the end of a handle secured to the stationary portion of the guide.

Claim 8

The cutting guide of claim 1 further comprising pins to affix the cutting guide to the bone to be cut.

Claim 9

The cutting guide of claim 4 in which the stationary guiding surfaces are at different angles with respect to the bone to be cut.

Claim 10

The cutting guide of claim 4 which comprises at least four stationary guiding surfaces.

Claim 11

A cutting guide to guide a cutting device to make cuts in a distal femur to prepare the distal femur to receive the femoral component of a total knee prosthesis comprising: a body having as two first fixed guiding surfaces which are set at angels to the bone to be cut of from 0° to 10°, two first movable surfaces movable attached to the body which are capable of being moved toward or away from the two first fixed surfaces to create slots to receive and position a cutting device with respect to the bone to be cut; two second fixed guiding surfaces which are set at an angle of 40° to 50° to the bone to be cut, two second movable surfaces attached to the body which are capable of being moved toward or away from the two second fixed surfaces to create slots to receive and position a cutting device with respect to the bone to be cut.

Claim 12

A cutting guide to guide a cutting device to make cuts in a distal femur to prepare the distal femur to receive the femoral component of a total knee prosthesis comprising: a body having as two first fixed guiding surfaces which are set at angels to the bone to be cut of from 0° to 10°, two first movable surfaces movable attached to the body which are capable of being moved toward or away from the two first fixed surfaces to create slots to receive and position a cutting device with respect to the bone to be cut; two second fixed guiding surfaces which are set at an angle of 40° to 50° to the bone to be cut, two second movable surfaces attached to the body which are capable of being moved toward or away from the two second fixed surfaces to create slots to receive and position a cutting device with respect to the bone to be cut.
