Abstract
The present disclosure relates to an instrument. The instrument includes a handle coupled with a rod, and a body portion configured to receive the rod in a central portion thereof. The instrument also includes a coupling portion configured to releasably couple with one or more components of an implant. Actuation of the handle drives the rod to actuate a first implant component relative to a second implant component so as to position the first implant component adjacent the second implant component.
Claims17
A system, comprising;
- an implant system, comprising:
- a tibial component;
- a talar component;
- an intermediate component;
- and
- an instrument comprising:
- a handle portion coupled to a rod;
- a head portion comprising a releasable coupling portion configured to releasably couple with the tibial component, wherein the head portion is configured to releasably couple with the intermediate component, and wherein the coupling portion comprises a protrusion extending from an upper portion of the coupling portion, wherein the protrusion comprises:
- a projection for engaging at least a portion of the tibial component, wherein the projection comprises:
- a catch disposed on an end of the projection;
- and
- a notch defined by the catch to couple with the tibial component;
- an engagement feature on a bottom surface of the protrusion, wherein the engagement feature slidingly couples with the intermediate component, and wherein the rod contacts with the intermediate component to translate the intermediate component relative to the coupling portion;
- and
- a body portion, wherein the body portion is disposed between the handle portion and the head portion.
An instrument comprising:
- a handle coupled with a rod;
- a body portion comprising a first end and a head portion, the body portion configured to receive the rod in a central portion thereof;
- and
- a coupling portion configured to releasably couple with one or more components of an implant system, wherein the coupling portion comprises a protrusion extending from an upper portion of the coupling portion, wherein the protrusion comprises:
- a projection configured to engage at least a portion of a first component of the one or more components of the implant system, wherein the projection comprises:
- a catch disposed on an end of the projection;
- and
- a notch defined by the catch and configured to couple with the first component of the one or more components of the implant system;
- an engagement feature on a bottom surface of the protrusion, wherein the engagement feature is configured to slidingly couple with a second component of the one or more components of the implant system, and wherein the rod is configured to contact the second component to translate the second component relative to the coupling portion.
A method for positioning implant components, comprising:
- selecting a desired size of a first implant component and a corresponding size of a second implant component;
- releasably coupling the first implant component and the second implant component with a distal end of an insertion instrument, wherein the first implant component is arranged superior relative to the second implant component, wherein the insertion instrument comprises:
- a handle coupled with a rod;
- a body portion comprising a first end and a head portion, the body portion configured to receive the rod in a central portion thereof;
- and
- a coupling portion configured to releasably couple with one or more of the first implant component and the second implant component, wherein the coupling portion comprises a protrusion extending from an upper portion of the coupling portion, wherein the protrusion comprises:
- a projection configured to engage at least a portion of the first implant component, wherein the projection comprises:
- a catch disposed on an end of the projection;
- and
- a notch defined by the catch and configured to couple with the first implant component;
- an engagement feature on a bottom surface of the protrusion, wherein the engagement feature slidingly couples with the second implant component, and wherein the rod contacts the second implant component to translate the second implant component relative to the coupling portion;
- selectively repositioning the second implant component relative to the first implant component;
- positioning the first and second implant components relative to a tibia of a patient;
- and
- decoupling the first and second implant components from the insertion instrument.
