Abstract

An electronically assisted artificial vertebral disc having an upper disc plate and a lower disc plate is disclosed. An actuator imparts movement to at least one of the upper and lower disc plates. A control device controls the actuator and the amount of movement between the disc plates. The actuator includes a plurality of either linear actuators or rotary actuators that are driven by electric motors in response to the control device. The control device includes at least a first sensor for detecting the position of the actuator and at least a second sensor for detecting the spatial orientation of at least one of the upper and lower disc plates. The control device also preferably includes a microprocessor that calculates the desired positions of the upper and lower disc plates and provides a control signal to the actuator to drive the upper and lower disc plates to their desired positions.

Dependent claims

An electronically assisted artificial disc comprising:

an upper disc plate having a first outer surface configured to engage a first vertebral body and a first inner surface opposite the first outer surface;
a lower disc plate having a second outer surface configured to engage a second vertebral body and a second inner surface opposite the second outer surface;
a core positioned between the first inner surface of the upper disc plate and the second inner surface of the lower disc plate;
a sensor configured to detect a condition of the electronically assisted artificial disc;
a microprocessor in communication with the sensor, the microprocessor configured to:
receive from the sensor the detected condition of the electronically assisted artificial disc, and
generate a control signal providing an instruction to adjust the electronically assisted artificial disc;
and
an actuator assembly positioned between the upper disc plate and the lower disc plate to surround the core, the actuator assembly configured to adjust a position of the upper disc plate relative to the lower disc plate, the actuator assembly configured to:
receive the control signal from the microprocessor;
and
move the upper disc plate relative to the lower disc plate based on the received control signal.
