A step (S200) of acquiring an image of a fractured portion of the marked patient through an image capturing unit;

An initial three-dimensional model generating an initial three-dimensional model in which a reference point is marked by the information processing apparatus 300 provided with the display unit 310 receiving the photographed image for acquiring the fractured region image of the patient, Based on the marked reference points for screw fixation of the fracture site through the initial three-dimensional model, at least one standard data, which is the reference position for the surgical position and the length, direction, and tilt information for the screw 50, Adding standard data (S300);

A step of inputting the standard data to an initial three-dimensional model by the information processing apparatus 300 into a micro control unit (MCU) 230 included in a control module 200 of the guide device 100 for orthopedic surgery S400);

The three-dimensional model may include any corresponding anatomical group of fracture sites of a particular patient. The data associated with the three-dimensional model may be modeled from a scan of the imaging site of the MRI or CT or from radiographs of the patient's corresponding bone anatomy (or alternatively from another data source). Once the modeled data is known, the data information can be converted into a CAD program representative of the three-dimensional model using the known software tools and additional data to form the contours, sizes, shapes and orientations of one or more devices to be used in surgical operations Lt; RTI ID = 0.0 > points. ≪ / RTI >

According to an alternative embodiment, the data may be obtained from an ultrasonic or nuclear medical scanning device. In yet another alternative embodiment, it may be desirable to produce an apparatus designed to remain in the patient after the surgical operation is completed, in particular if the surgical operation involves the insertion of one or more implantable devices, To achieve additional control over the orientation, data may be supplemented or merged with data from a bone density scanner.

The measurement data and standard data stored in the database unit 231 included in the micro control unit 230 are compared with the measurement data measured by the sensor modules 210 and 220 through the comparison and determination unit 232 The motion of the body 110 and the screw 50 of the guide device 100 may be compared with the standard data so that the matching information may be displayed on the display unit 310 of the information processing apparatus 300 or on a separate display It is checked whether or not the data is coincident with the data value displayed in the part.

The orthodontic surgery guide device 200 is placed at the surgical site point of the patient, and the measurement data, which is input through the motion sensor module 210 of the body part 110 held or supported by the operator, (S500) of transmitting the information to the information processing apparatus (300) through the transmission / reception unit (240) of the MCU (230) and displaying the information on the display unit (310);

A step (S600) of correcting the body part (110) so that the measurement data and the standard data coincide with each other by the information processing device (300);

The screw 50 is inserted through the guide hole 111 of the body part 110 of the guide device 100 and the moving distance of the screw 50 is sensed by the distance sensor module 210 of the body part 110 Transmitting measurement values to the micro control unit 230 to generate measurement data (S700);

The step of correcting the measurement data and the standard data by the motion sensor module 220 described above is continuously corrected while inserting the screw 50 into the guide hole 111 of the body part 110.

The measurement data of the distance sensor module 210 stored in the micro control unit 230 is transferred to and displayed on the information processing apparatus 300 and the display unit 310 through the transmission and reception unit 240 to compare and analyze the standard data and the measurement data. And fixing the screw 50 to the bone 60 while checking and comparing the data displayed on the display unit 310 (S800).

The present invention may be advantageous in terms of recent improvements that rely on the skilled artisan of existing operators. For example, devices, guides and instruments may include on-site manufacturing locations, off-site manufacturing locations, surgeons or offices, or on-site manufacturing locations using equipment residing in public or private hospitals, in a number of different and convenient settings But may be manufactured in a position not limited thereto. In this manner, the process of obtaining the patient's measurement data information, the simulation standard data information of the three-dimensional model, and the correct fixation device, guide, or device may be enabled by the proximity of the manufacturing process and considered within the scope of the present invention.
