Description
Technical field
The utility model belongs to medical equipment technical field, and in particular to a kind of vertebra locating guiding template.
Background technology
With the lifting of computer application, medical technology is equiped with arms with digitizing technique, medical science is had a revolutionary change.
Meanwhile, the characteristics of 3D printing technique has individuation, the diagnosis and treatment theory with modern medicine is consistent, is heaven-made match.At present,
People carry out treatment to medical data and form skeleton model using digital computer technology, show the anatomical structure of bone,
Sham operated in computer, can design operation preferred plan, improve operation precise degrees.
Vertebra Minimally Invasive Surgery method is a new direction of present spinal surgery, but pedicles of vertebrae Kirschner wire is tiny,
Individual variability is big, if being placed into Kirschner wire and screw position is improper, nerve and injury of blood vessel is easily caused, while in also affecting
The stability of fixed system, therefore, the accuracy of operation is low, and operation risk is high, and operating time is long, to the radiation hazradial bundle of patient
Greatly.The accuracy of Kirschner wire and screw is placed into improve, it should be highlighted that individuation and precision put nail, consider Kirschner wire and enter
The positioning of pin mark, inserts the angle of screw and the diameter of screw and length three aspect factor.Therefore a kind of accurate safety is sought,
Putting nail method seems most important easily to operate.
Utility model content
The purpose of this utility model is to provide a kind of vertebra locating guiding template, can be made using the vertebra locating guiding template
Kirschner wire entry point accurate positioning.
The technical scheme that the utility model is used is that a kind of vertebra locating guiding template, including the bone face of a few fonts is pasted
Matched moulds block, is provided with the inside of bone face laminating module and to be put the nail bone that fits of vertebra lamina curved surface and fit curved surface,
Clamp hole and a pair of positioning and guiding passages are provided with bone face laminating module, a pair of positioning and guiding passages are fitted respectively close to bone face
The two ends of module, pilot hole is provided with each positioning and guiding passage.
The characteristics of the utility model, also resides in,
Clamp hole sets two, and two clamp holes are respectively positioned between a pair of positioning and guiding passages.
Each positioning and guiding passage is cylinder, and pilot hole is located at the axis direction of positioning and guiding passage.
Bone face laminating module, positioning and guiding passage, pilot hole, clamp hole and bone laminating curved surface pass through 3D printing integrally
Shaping.
The beneficial effects of the utility model are：A kind of vertebra locating guiding template is by setting bone face laminating module, bone face
The bone laminating curved surface of module of fitting fits with to be put nail vertebra lamina curved surface, while being fitted by bone with gripper clamp
Clamp hole in module will be put nail vertebra and the utility model is fixed together, then by Kirschner wire through pilot hole through fixed
On the guide channel of position, Kirschner wire entry point accurate positioning.The utility model improves the accuracy of operation, reduces operation wind
Danger, shortens operating time, reduces the radiation hazradial bundle to patient.
