SURGICAL SYSTEM AND METHOD FOR FORMING LESS THAN ALL BONE CUT SURFACES FOR IMPLANT PLACEMENT
A method to assist in forming one or more cut surfaces on a bone in preparation for contact with one or more contact surfaces of an implant is provided. Cutting instructions are provided to direct a computer-assisted surgical (CAS) device during formation of a first number of cut surfaces on the bone. The first number of cut surfaces being less than a total number of contact surfaces of the implant. A system for the practice of the method is also provided.
1 . A method to assist in forming one or more cut surfaces on a bone in preparation for contact with one or more contact surfaces of an implant, the method comprising:
providing cutting instructions to direct a computer-assisted surgical (CAS) device during formation of a first number of cut surfaces on the bone, wherein the first number of cut surfaces is less than a total number of contact surfaces of the implant.
2 . The method of claim 1 , further comprising directing the formation of the first number of cut surfaces on the bone with the CAS device according to the cutting instructions.
3 . The method of claim 2 , further comprising instructing a user to form additional cut surfaces on the bone without the CAS device, or to utilize manual instrumentation to form additional cut surfaces on the bone.
4 . (canceled)
5 . The method of claim 3 , wherein the first number of cut surfaces formed using the CAS device plus the number of additional cut surfaces correspond to the total number of contact surfaces of the implant.
6 . The method of claim 1 , further comprising using planning software to plan a position for the first number of cut surfaces relative to pre-operative bone data.
7 . The method of claim 1 , wherein the cutting instructions are part of a total knee arthroplasty (TKA) procedure.
8 . (canceled)
9 . The method of claim 1 , wherein the cutting instructions are part of a unicondylar knee arthroplasty (UKA) procedure.
10 . (canceled)
11 . (canceled)
12 . The method of claim 1 , wherein the implant is unsupported by the CAS device.
13 . The method of claim 1 , wherein the cutting instructions comprise at least one of a cut-file, one or more virtual boundaries, or one or more virtual paths, one or more cut paths situated along a single plane, along a single line, or in three-dimensions, or define a cut volume, wherein the cut volume has a general shape.
14 . (canceled)
15 . (canceled)
16 . The method of claim 1 , wherein the CAS device is an active surgical robot, a semi-active surgical robot, or a haptic surgical robot.
17 . The method of claim 1 , wherein the cutting instructions direct the CAS device during the formation of a second number of cut surfaces on a second bone, wherein the second number of cut surfaces is equal to or less than a total number of contact surfaces of a second implant.
18 . (canceled)
19 . The method of claim 2 wherein the CAS device is capable of forming a number of cut surfaces on the bone that is equal to or greater than the total number of contact surfaces of the implant.
20 . A system comprising:
cutting instructions to direct a CAS device to form a first number of cut surfaces on a bone, wherein the first number of cut surfaces is less than the total number of contact surfaces of an implant.
21 . The system of claim 20 , further comprising:
a CAS device directed by the cutting instructions during the formation of the first number of cut surfaces on the bone.
22 . The system of claim 20 , further comprising a mechanism to instruct a user to form additional cut surfaces on the bone without the CAS device, or to complete additional cuts surfaces on the bone with manual instrumentation.
23 . (canceled)
24 . The system of claim 22 , wherein the mechanism comprises at least one of: text on a display monitor; a graphic on a display monitor; a graphical user interface (GUI); an instruction manual; a user's manual; a technical data sheet; release notes; instructions-for-use (IFUs); and equivalents thereof.
25 . (canceled)
26 . The system of claim 20 , further comprising planning software to plan a position for the first number of cut surfaces relative to pre-operative bone data.
27 . (canceled)
28 . (canceled)
29 . (canceled)
30 . (canceled)
31 . (canceled)
32 . (canceled)
33 . The system of claim 20 , wherein the cutting instructions comprises at least one of a cut-file, one or more virtual boundaries, or one or more virtual paths, one or more cut paths situated along a single plane, along a single line, or in three-dimensions, or a cut volume with a general shape.
34 . (canceled)
35 . (canceled)
36 . The system of claim 20 , wherein the CAS device is at least one of an active surgical robot, a semi-active surgical robot, or a haptic surgical robot.
37 . (canceled)
