Devices, systems and methods for manufacturing orthopedic implants
Methods, system, devices, processes and techniques are disclosed for manufacturing orthopedic implants utilizing blanks and/or fixtures.
1. A fixture for use in manufacturing a surgical implant for treating a portion of a bone of a patient, the fixture comprising:
an outer surface, the outer surface including:
an engagement portion configured to engage a patient-specific portion of the implant in a known orientation during at least a portion of the manufacturing of the implant; and
a connecting portion, the connecting portion configured for releasably connecting to one or more processing apparatuses in a predetermined orientation,
wherein the engagement portion includes first and second holes, the first and second holes sized and positioned to accommodate first and second pegs, respectively, extending from the implant when the implant is engaged with the engagement portion in the known orientation.
2. The fixture of claim 1 , wherein the engagement portion of the outer surface of the fixture substantially matches one or more planned bone-cut surfaces of the portion of the bone of the patient.
3. The fixture of claim 1 , wherein the portion of the implant comprises one or more bone-facing surfaces of the implant.
4. The fixture of claim 3 , wherein the engagement portion of the outer surface of the fixture substantially mirrors the one or more bone-facing surfaces of the implant.
5. The fixture of claim 1 , wherein the connecting portion is configured to be secured in a predetermined orientation to a connector for connecting to the one or more processing apparatuses.
6. The fixture of claim 1 , wherein the connector is a chuck.
7. A set of fixtures for use in manufacturing patient-specific knee implants, the set of fixtures comprising:
a first fixture for use in manufacturing a first implant for treating a portion of a femur of a first patient, the first fixture comprising:
an outer surface, the outer surface including:
an engagement portion configured to engage a patient-specific_portion of the first implant in a known orientation during at least a portion of the manufacturing of the first implant; and
a connecting portion, the connecting portion configured for releasably connecting to one or more processing apparatuses in a predetermined orientation,
wherein the engagement portion includes:
a first hole sized to accommodate a first peg extending from the first implant, the first hole located in a standard, fixed location relative to the connecting portion; and
a second hole sized to accommodate a second peg extending from the first implant, the second hole located in a patient-specific location based on the location of the second peg relative to the first peg of the first implant; and
a second fixture for use in manufacturing a second implant for treating a portion of a femur of a second patient, the second fixture comprising:
an outer surface, the outer surface including:
an engagement portion configured to engage a patient-specific_portion of the second implant in a known orientation during at least a portion of the manufacturing of the second implant; and
a connecting portion, the connecting portion configured for releasably connecting to one or more processing apparatuses in a predetermined orientation,
wherein the engagement portion includes:
a first hole sized to accommodate a first peg extending from the second implant, the first hole located in the standard, fixed location relative to the connecting portion; and
a second hole sized to accommodate a second peg extending from the second implant, the second hole located in a patient-specific location based on the location of the second peg relative to the first peg of the second implant,
wherein the first and second hole of the first fixture are separated by a distance that is not equal to the distance separating the first and second hole of the second fixture.
