The guide plate base is provided with a first fixing guide pipe and a second fixing guide pipe, the first fixing guide pipe is positioned in a first hole on the inner side of a fracture line on the reduction clavicle steel plate, and the direction of the first fixing guide pipe is consistent with the nail placing direction of the nail hole; the second fixing guide pipe is positioned in a first hole on the outer side of the fracture line on the reduction clavicle steel plate, and the direction of the second fixing guide pipe is consistent with the nail placing direction of the nail hole. The first fixing guide pipe and the second fixing guide pipe are used for extending the reset clavicle steel plate sleeve into the first fixing guide pipe and the second fixing guide pipe to play a role in fixing and guiding. The guide plate base is provided with a first fixing hole, the first fixing hole is perpendicular to the fracture line in front of the guide plate base, and a guide pin is used for temporarily fixing the fracture end through the first fixing hole during surgery, so that a lag screw is fixed at the fracture end. Be equipped with fixed orifices two, fixed orifices three on the baffle base, its in the preceding free bone piece fracture line of perpendicular to of baffle base, use the guide pin to pass through fixed orifices two, three temporary fixed free bone pieces of fixed orifices during the operation, use lag screw to be fixed in the fracture end with free bone piece then. And a fixing hole IV is formed in the guide plate base, is perpendicular to the fixing hole II and the fixing hole III, and is used for temporarily fixing free bone blocks in an auxiliary mode through the fixing hole IV by using a guide pin in an operation.
Realize the utility model discloses a workflow contains following step:
(1) Data acquisition: CT data of the clavicle on the affected side and the healthy side of the patient are obtained by using 1mm thin-layer CT scanning and are exported by a DICOM file.
(2) Establishing a clavicle model: and importing the image data into a Mimics software, establishing a 3D digital model of the clavicle at the affected side and a mirror image model of the healthy side, and carrying out 3D printing in equal proportion.
(3) The clavicle fracture simulation reduction model is established: and (3) resetting the fracture on the affected side by using Mimics software according to the anatomical features of the clavicle on the healthy side to obtain a reset model.
(4) Establishing an operation guide plate model: the operation guide plate is established on the basis of the diseased side clavicle reduction model, and a fixing guide pipe and a fixing hole are arranged on the guide plate base according to the shape of the reduction clavicle, the position of a fracture line and the position of a free bone block.
(5) Printing the surgical guide plate: and (4) leading the established guide plate model into a 3D printer, and printing out the operation guide plate.
The utility model discloses have as follows and show the effect:
use the utility model discloses effectual accurate location, put the nail and fix comminuted clavicle fracture, shortened the operation time of internal fixation art greatly. Adopt 3D to print operation baffle technique can reduce the art in the repeated operation, can accomplish through disposable operation, guarantee baffle and fracture collar-bone can accurate laminating, reduce the maloperation, for the operation brings very big facility, be fit for vast medical institution and use widely.
