Abstract:
An external fixation device includes a frame assembly having a first arc segment and a second arc segment. The first arc segment is for interconnection to a first bone portion. The second arc segment is for interconnection to a second bone portion. The first arc segment is coupled to the second arc segment for relative rotation. The external fixation assembly additionally includes an articulating module. The articulating module includes a central member, a first pivot segment and a second pivot segment. The first pivot segment is coupled to the central member for driven rotation about a first pivot axis. The second pivot segment is coupled to the central member for driven rotation about a second pivot axis. The second pivot axis is substantially perpendicular to the first pivot axis.
Abstract:
A laser measuring method in a laser measuring system, which comprises a rotary laser system for projecting a laser beam by rotary irradiation and at least one photodetection system having at least one photodetector for receiving the laser beam, comprising a step of emitting at least two fan-shaped laser beams by the rotary laser system, at least one of the fan-shaped laser beams being tilted, a step of receiving the laser beams at least at three known points by the photodetection system, a step of obtaining elevation angles with respect to the rotary laser system based on photodetection signals which are formed when the photodetector receives the laser beam, and a step of measuring an installing position of the rotary laser system based on elevation angles and position data at the three known points.
Abstract:
Frame assembly for external fixation device and associated method. The frame assembly includes a first arc segment and a second arc segment. The first arc segment is for interconnection to a first bone portion. The second arc segment is for interconnection to a second bone portion. The first arc segment is coupled to the second arc segment for controlled relative rotation.
