A broad aspect of some embodiments relates to coupling, for example selectively coupling a motor unit to a strut, for example a strut of an orthopedic fixation device, for example an external bone fixation device.
An aspect of some embodiments relates to restraining a movement of a motor unit coupled to the strut. In some embodiments, the movement of the motor unit, for example lateral and/or axial movement, is restrained when the motor unit is coupled to the strut. In some embodiments, the movement of the motor unit relative to the strut is restrained. Optionally, the movement of the motor unit relative to a linear actuator of the strut is restrained. In some embodiments, the motor unit is a detachable motor unit, configured to attach and detach, for example selectively, from the strut.
According to some embodiments, the motor unit is selectively coupled to the strut via an adaptor, for example a motor adaptor. In some embodiments, the motor adaptor comprises at least one motor restrainer, configured to restrain the movement of the motor unit. In some embodiments, the restrainer of the motor adaptor is configured to restrain lateral and/or axial movement of the motor unit. In some embodiments, the motor unit comprises a motor, a driving shaft of the motor and a gear of the motor. In some embodiments, a gear of the motor, is selectively coupled to the linear actuator, for example to a gear of the linear actuator.
According to some embodiments, the motor unit interlocks, for example to a motor adaptor that is connected to the linear actuator. In some embodiments, a restrainer of the motor adaptor interlocks the motor unit with the linear actuator. Optionally, the restrainer of the motor adaptor interlocks a gear of the motor unit or at least one end of the motor with a gear of the linear actuator.
An aspect of some embodiments relates to using the same adaptor coupled to a strut for both manual and motorized adjustments of the strut. In some embodiments, manual-induced movement and motorized induced movement is delivered to an actuator of the strut, for example a linear actuator, through the same transmission element. In some embodiments, the transmission element is a transmission element coupled to the linear actuator, for example to a gear of the linear actuator.
According to some embodiments, the motor unit and a manual interface for delivering the manual-induced movement are connected in parallel to the same transmission element. Alternatively, the motor unit and the manual interface are interchangeable.
An aspect of some embodiments relates to delivering movement to a linear actuator of a strut near an extending portion of the strut. In some embodiments, a transmission element, for example a motorized gear, contacts the linear actuator near an extending portion of the strut, for example at a distance smaller than 10 cm, smaller than 8 cm, smaller than 5 cm, smaller than 3 cm, smaller than 2 cm or any intermediate, smaller or larger distance from an extending portion of the strut.
According to some embodiments, a motor unit is coupled to a strut, near an extending portion of the strut and distant from a fixed end of the strut, for example at a distance smaller than 10 cm, smaller than 8 cm, smaller than 5 cm, smaller than 3 cm, smaller than 2 cm or any intermediate, smaller or larger distance from an extending portion of the strut. As used herein, the term near means closer to a first location and distant from a second location.

In some embodiments, an angle between a plane perpendicular and tangent to the ring, and a transverse axis of the strut assembly is adjusted. In some embodiments, the angle is adjusted by rotating a strut of the strut assembly around a longitudinal axis of the strut. Optionally, the angle is adjusted prior to coupling a motor unit to the motor adaptor of the strut assembly. Alternatively, the angle is adjusted when the motor unit is coupled to the motor adaptor.
According to some embodiments, the strut assembly is locked at a desired angle relative to a frame or plane perpendicular and tangent to the frame, by a lock, for example a screw or a pin that controls a rotational movement of a strut of a strut assembly around a longitudinal axis of the strut.
According to some embodiments, length and/or position of wires connecting the motor unit and/or the motor adaptor to a control unit of the bone fixation device, are adjusted. In some embodiments, the wires length and/or position are adjusted to minimize interference to the treatment, for example to minimize potential interactions between the wires and an external object. In some embodiments, the wires are attached to at least a portion of a bone fixation device, for example by a wire attachment clip. Alternatively or additionally, wires from two or more sources are attached to the bone fixation device using a wire splitter attachment.
