First Claim
Patent Images
1. An orthopedic implant comprising:
- at least one adjustment mechanism configured for securing to at least one orthopedic structure of a subject, the at least one adjustment mechanism consisting of tension band wiring in combination with one or more of pins, screws, or intramedullary nails or rods;
at least six one motors directly connected to the at least one adjustment mechanism, wherein the at least six motors are configured to move the at least one adjustment mechanism in six degrees of freedom;
at least one ultrasonic actuator operably connected to the at least six motors, the ultrasonic actuator is operable to power the at least six motors from an energy source configured to be remote from the orthopedic implant and operably coupled to the at least one ultrasonic actuator via ultrasonic energy;
a controller and a transmitter;
a sensor in communication with the controller and the transmitter, the sensor including circuitry for detecting a change in at least one of strain, pressure, or position of the at least one adjustment mechanism of the orthopedic implant when operably secured to the at least one orthopedic structure;
the transmitter including circuitry for transcutaneously reporting to a network configured to be remote from the orthopedic implant, information from the sensor indicative of the detected change;
the controller including circuitry for receiving energy from the remote energy source operably coupled to the at least one ultrasonic actuator via ultrasonic energy to remotely power the at least one motor to move the at least one adjustment mechanism of the orthopedic implant responsive to receiving reporting information indicative of the detected change in the at least one adjustment mechanism; and
the controller including circuitry for transcutaneously receiving control commands from the remote network to the controller to cause movement of the at least one adjustment mechanism responsive to reporting information from the sensor and the transmitter indicative of the detected change to adjust the curvature of the at least one orthopedic structure.
