Abstract
An adjustable bone fixation device for moving a bone includes at least two strut units, at least one meter and a system controller. Each strut unit includes a motor to move a strut. The meter measures a signal generated by the motor during the movement of its strut. The signal is useful in determining a torque or a current of the motor. The system controller activates at least two of the motors and uses the determined torque or the determined current to identify if there is a clinical situation of the bone or a system issue and provides an alert accordingly.
Claims23
An adjustable bone fixation device for moving a bone, the adjustable bone fixation device comprising:
- at least two strut units, each strut unit of the at least two strut units comprising a motor to move a strut;
- at least one meter to measure a signal generated by the motor during a movement of the respective strut, said signal useful in determining a torque or a current of said motor;
- a system controller to activate at least two motors of the at least two strut units and to determine said torque or said current of the at least two motors;
- and
- an alert processor to identify if said determined torque or said determined current indicates a clinical situation of the bone or a system issue and to provide an alert accordingly, wherein the alert processor determines if a strut swap was not done or was forgotten and provides an appropriate alert.
A method for an adjustable bone fixation device for moving a bone, the adjustable bone fixation device having at least two strut units, each strut unit of the at least two strut units comprising a motor to move a strut, the method comprising:
- activating at least two motors of the at least two strut units;
- measuring signals generated by said at least two activated motors, said signals useful in determining torques or currents of said at least two motors;
- and
- identifying if the determined torques or currents indicate a clinical situation of the bone or a system issue and alerting accordingly, wherein identifying if the determined torques or currents indicate the clinical situation comprises determining if a strut swap was not done or was forgotten and providing an appropriate alert.
