摘要： Provided is a laser projection apparatus, a control method thereof, and a laser guidance system including the laser projection apparatus. The laser projection apparatus for projecting planned operation information of an insertion location and an insertion angle on a C-arm image photographed using a C-arm fluoroscopy device directly onto an affected part includes a line laser module configured to generate a line laser and to form a plane by rotating around an origin, a matching unit configured to calculate a coordinate representing the insertion location in a C-arm coordinate system based on C-arm fluoroscopy, calculate an insertional vector according to the coordinate representing the insertion location and the insertion angle, and calculate a vector perpendicular to the plane formed by the line laser in the C-arm coordinate system according to the insertional vector, and a control unit configured to control the line laser module based on the vector perpendicular to the plane.

摘要： This disclosure relates to an active retractor implemented to detect a stress state of a fractured area during fracture reposition and compensate for a required retracting force, and a control method thereof. The active retractor includes: a retracting shaft configured to fasten fractured bone fragments of a patient and retract the fractured bone fragments in a front and rear direction; a measuring device connected and installed to the retracting shaft to measure a retracting location or a retracting force of the retracting shaft; an actuator connected and installed to the retracting shaft to drive the retracting shaft in the front and rear direction; a driver configured to supply a power required for driving the actuator to the actuator according to a driving control signal; and a controller configured to generate a driving control signal, which is required for the driver to supply a power, by comparing a retracting request signal input from a user with a measured value transmitted from the measuring device and transmit the driving control signal to the driver.
