Augmented, just-in-time, patient-specific implant manufacture
A bone part is repaired by a process. A first implant is attached to a first bone part. The first implant corresponds to an intraoperatively defined or an intraoperatively selected cutting path. A preoperatively defined second implant is attached to the first implant. The first implant and the second implant together augment the first bone part.
1 . A system for repairing a bone part, comprising:
a cutting path data file;
an implant data file;
a first implant corresponding to an intraoperatively defined cutting path that is stored in the cutting path data file; and
a second implant that is preoperatively defined and attached to the first implant,
wherein the first implant is at least partially fabricated intraoperatively from the implant data file prepared using the cutting path data file, and
wherein the first implant is attached to a first bone part such that the first and the second implants together augment the first bone part.
2 . The system of claim 1 , wherein the second implant is attached to a second bone part such that a joint is formed by the first implant, the second implant, the first bone part, and the second bone part.
3 . The system of claim 1 , wherein first implant and the first bone part are attached via a tongue-and-groove joint.
4 . The system of claim 1 , wherein the cutting path data file includes a preoperatively planned cutting path configured to resect an initial bone part to form an intermediate bone part, the preoperatively planned cutting path differs from the intraoperatively defined cutting path.
5 . The system of claim 1 , wherein the second implant is an implant selected from a group of implants consisting of a hip implant, a shoulder implant, a femoral implant, a tibial implant, a spine implant, a wrist implant, and a foot implant.
6 . The system of claim 5 , wherein either one or both of the first implant and the second implant is a shim.
7 . The system of claim 1 , further comprising a robot configured to perform robotic surgery.
8 . The system of claim 1 , wherein the first implant is a three-dimensional (3D) printed implant.
9 . The system of claim 8 , further comprising a computer-aided design (CAD) model corresponding to the 3D printed implant and stored in the implant data file.
10 . The system of claim 1 , further comprising either one or both of a computer numerically controlled (CNC) mill or CNC lath configured to fabricate the first implant from a block of material.
11 . The system of claim 1 , wherein either one or both of the first implant and the second implant have any of a lattice structure, a unit cell structure, a woven structure, or a chain mail structure.
12 . A system for repairing a bone part, comprising:
a cutting path data file;
a first implant corresponding to an intraoperatively selected cutting path that is stored in the cutting path data file; and
a second implant that is preoperatively defined,
wherein the first implant is at least partially fabricated intraoperatively from an implant CAD model prepared using the cutting path data file.
13 . The system of claim 12 , wherein the second implant has a predetermined structure corresponding to a CAD model.
14 . The system of claim 12 , wherein either one or both of the first implant and the second implant is a patient-specific implant.
15 . The system of claim 12 , further comprising a plurality of preset cutting paths preoperatively stored in respective data files.
16 . The system of claim 15 , wherein the intraoperatively selected cutting path is one of the plurality of preset cutting paths.
17 . The system of claim 12 , wherein a fabrication device configured to intraoperatively fabricate the first implant is disposed within an operating room.
18 . The system of claim 12 , wherein either one or both of the first implant and the second implant are fabricated from a biocompatible metal.
19 . The system of claim 12 , further comprising a fabrication device configured to fabricate the first implant intraoperatively.
