Abstract

Claims (12)

1. A modular bone resection guide system comprising:

a positioning base configured to be attached to a bone;

a modular resection block configured to be removably attached to various locations of the positioning base;

a cutting tool configured to be supported and guided by the modular resection block while cutting the bone;

wherein the modular resection block comprises parallelepiped body having a first slot extending from a front surface to a back surface of the parallelepiped body and wherein said first slot is shaped and dimensioned to slidably support and guide the cutting tool;

wherein the cutting tool comprises a saw blade and wherein the saw blade comprises an elongated body extending along a first direction and having a rounded proximal end and a straight distal end and wherein the distal end comprises saw teeth;

wherein the elongated body of the saw blade further comprises an elongated slot extending along the first direction and wherein the modular resection block further comprises an elongated second slot perpendicular to said first slot and extending along a second direction and wherein said second direction intersects said first direction at a first location and wherein a fastening screw is inserted into said first location and secures the position of the saw blade along the second direction relative to the modular resection block, while allowing the saw blade to slide along the first direction within the first slot of the modular resection block.

2. The system of claim 1 , wherein the positioning base comprises a parallelepiped body having a central through-opening and a plurality of peripheral openings surrounding said central through opening.

3. The system of claim 2 , wherein the modular resection block further comprises first and second pins and wherein said modular resection block is removably attached to the positioning base by inserting the first and second pins into first and second peripheral openings of the positioning base, respectively.

4. The system of claim 1 , wherein said rounded proximal end comprises a through opening shaped and dimensioned to support a power tool.

5. The system of claim 1 , wherein the positioning base comprises an outer surface contoured to fit the bone's surface anatomy.

6. The system of claim 1 , wherein the cutting tool comprises one of knifes, scissors, milling devices, drills, or blades.
