Abstract
A load sensing assembly for a spinal implant includes a set screw having a central opening that extends from a first end of the set screw toward a second end of the set screw. The second end of the set screw is configured to engage with an anchoring member. The load sensing assembly includes an antenna, an integrated circuit in communication with the antenna, where the integrated circuit is positioned within the central opening of the set screw, and a strain gauge in connection with the integrated circuit. The strain gauge is located within the central opening of the set screw in proximity to the second end of the set screw.
Claims19
A load sensing assembly for a spinal implant, the load sensing assembly comprising:
- a set screw comprising a central opening that extends from a first end of the set screw toward a second end of the set screw, wherein the second end of the set screw is configured to engage with an anchoring member receiving a rod;
- an antenna;
- an integrated circuit in communication with the antenna, wherein the integrated circuit is positioned within the central opening of the set screw;
- and
- a plurality of sensors in connection with the integrated circuit, wherein the plurality of sensors are located within the central opening of the set screw in proximity to the second end of the set screw,
- wherein at least one sensor of the plurality of sensors comprises a strain gauge configured to measure a localized force between the second end of the set screw and the rod.
A load sensing assembly for a spinal implant, the load sensing assembly comprising:
- a set screw extending from a first end to a second end, wherein the second end of the set screw is configured to engage with an anchoring member receiving a rod;
- an antenna;
- an electronics component comprising one or more electrical circuits, wherein the electronics component is operably connected to the antenna;
- an integrated circuit operably connected to at least a portion of the electronics component;
