Hybrid control of a cutting tool

Abstract

A system for preparing a bone for receiving an implant is described. The system includes a cutting tool and a cutting guide. The cutting tool includes a cut guard configured to sheath at least a portion of a cutting surface of the cutting tool, and an engagement portion. The cutting guide includes a baseplate configured to be positioned onto the bone and a cut guide portion removably attached to the baseplate. The cut guide portion includes a cutting channel, the cutting channel being sized and shaped to receive the engagement portion of the cut guard and guide the cutting tool to cut a receiving channel into the bone, wherein the receiving channel includes a depth profile matching an implant to be inserted into the receiving channel.

1 . A device for use during an implant surgery, the device comprising:
 a cutting guide configured to be aligned with respect to a first bone to be cut   and comprising a cutting channel, the cutting channel being sized and shaped to:
 receive at least a portion of a cutting tool, and 
 guide the cutting tool to cut a receiving channel in the first bone to be cut, wherein the receiving channel comprises a depth profile matching an implant to be inserted into the receiving channel. 
   
     
     
         2 . (canceled) 
     
     
         3 . The device of  claim 1 , wherein the cutting channel comprises an internal shape configured to fit the at least a portion of the cutting tool. 
     
     
         4 . The device of  claim 1 , wherein the cutting guide is sized based upon the implant to be inserted into the receiving channel. 
     
     
         5 . The device of  claim 4 , wherein the cutting guide is sized to provide a receiving channel for a plurality of implant sizes. 
     
     
         6 . The device of  claim 1 , wherein the first bone to be cut comprises a tibia. 
     
     
         7 . The device of  claim 1 , wherein the cutting guide configured to:
 align to the first bone to be cut when a first side of the cutting guide is positioned up, and   align to a second bone to be cut when a second side of the cutting guide is positioned up.   
     
     
         8 .- 6 . (canceled) 
     
     
         17 . A method of preparing a bone to receive an implant, the method comprising:
 determining, by a computing system, a keel depth profile for the implant;   aligning, by the computing system, a cutting guide with respect to the bone, wherein the cutting guide comprises a cutting channel sized and shaped to receive at least a portion of a cutting tool; and   guiding the cutting tool to cut a receiving channel in the bone, wherein the receiving channel comprises a depth profile matching the keel depth profile of the implant.   
     
     
         18 .- 9 . (canceled) 
     
     
         20 . The method  claim 17 , wherein the bone comprises a tibia. 
     
     
         21 . The device of  claim 1 , wherein the cutting guide is configured to be coupled to a robotic arm, wherein the robotic arm is configured to align the cutting guide with respect to the first bone. 
     
     
         22 . The method of  claim 17 , wherein the cutting guide is configured to be coupled to a robotic arm, wherein aligning the cutting guide with respect to the bone comprises positioning, by the computing system, the robotic arm to align the cutting guide with respect to the bone. 
     
     
         23 . The method of  claim 17 , wherein the cutting channel comprises an internal shape configured to fit the at least a portion of the cutting tool. 
     
     
         24 . The method of  claim 17 , wherein the cutting guide is sized based upon the implant to be inserted into the receiving channel. 
     
     
         25 . The method of  claim 24 , wherein the cutting guide is sized to provide a receiving channel for a plurality of implant sizes. 
     
     
         26 . The method of  claim 17 , wherein the cutting guide is configured to:
 align to the bone when a first side of the cutting guide is positioned up, and   align to another bone when a second side of the cutting guide is positioned up.
