Devices and methods of accelerating bone cuts

Abstract

Methods of accelerating bone cuts, and the devices used therefore, are disclosed. The methods can involve the use of robotic cutting tools.

What is claimed is: 
     
         1 . A method of cutting bone comprising:
 forming a mark on a bone;   cutting the bone without robotic-guidance to remove a bulk amount of the bone up to a point slightly spaced apart from the mark on the bone; and   making a precision cut with a robotic cutting tool along the mark at a pre-defined trajectory so as to shape the bone for receiving an implant.   
     
     
         2 . The method  claim 1 , further comprising implanting the implant on the shaped bone. 
     
     
         3 . The method of  claim 1 , further comprising making the precision cut with the robotic cutting tool along the mark at the pre-defined trajectory so that the bone is shaped as a positive surface that conforms to a shape of a negative implant-to-bone interface of the implant. 
     
     
         4 . The method of  claim 1 , further comprising hand-cutting the bone using a saw, burr, or other cutting tool to remove the bulk amount of the bone. 
     
     
         5 . The method of  claim 4 , wherein hand-cutting comprises using a powered saw, burr, or other cutting tool that is manipulated by hand without the assistance of a robot. 
     
     
         6 . The method of  claim 1 , wherein the robotic cutting tool comprises a robotic cutting arm that has a laser. 
     
     
         7 . The method of  claim 6 , wherein the mark is formed on the bone using the laser with guidance from the robotic cutting tool. 
     
     
         8 . The method of  claim 1 , further comprising forming a plurality of marks on the bone, each of the marks establishing a starting point for cutting the bone. 
     
     
         9 . The method of  claim 8 , wherein each of the marks is a straight line. 
     
     
         10 . A method of cutting bone comprising:
 creating a pre-operative plan comprising a plurality of cutting planes for a patient's bone;   forming a plurality of marks on the bone, a first mark corresponding to a starting point of a first of the plurality of cutting planes, and a second mark corresponding to a starting point of a second of the plurality of cutting planes;   cutting the bone without robotic-guidance to remove a bulk amount of the bone up to a point slightly spaced apart from each mark;   making a precision cut using a robotic cutting tool along the first cutting plane starting at the first mark; and   making a precision cut using a robotic cutting tool along the second cutting plane starting at the second mark, wherein the precision cuts shape the bone to receive an implant.   
     
     
         11 . The method of  claim 10 , further comprising forming the plurality of marks on the bone using a laser. 
     
     
         12 . The method of  claim 11 , further comprising forming the plurality of marks on the bone using a robotically-guided laser. 
     
     
         13 . The method of  claim 10 , further comprising hand-cutting the bone using a saw, burr, or other cutting tool to remove the bulk amount of the bone. 
     
     
         14 . The method of  claim 10 , further comprising making the precision cuts using the robotic cutting tool so that the bone is shaped as a positive surface that conforms to a shape of a negative implant-to-bone interface of the implant.
