Fig. 1 is the side-looking structural representation of the free guide plate of individuation hip joint of the present invention;
Fig. 2 is the plan structure schematic diagram of the free guide plate of individuation hip joint of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments. Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
Refer to the side-looking structural representation that Fig. 1 and Fig. 2, Fig. 1 are the free guide plates of individuation hip joint of the present invention; Fig. 2 is the plan structure schematic diagram of the free guide plate of individuation hip joint of the present invention. The free guide plate of this individuation hip joint includes: guide plate body 10, depth localization base station 20, osteotomy groove 30 and hole 40, location.
The medial surface of guide plate body 10 be with patient's hip joint osteotomy line around sclerotin shape perfection laminating globoidal structure.
Depth localization base station 20 is arranged at the lateral surface of guide plate body 10, for the degree of depth in osteotomy limit osteotomy. The surface of depth localization base station 20 is arc.
Osteotomy groove 30 is opened on the cross central line of depth localization base station 20, runs through depth localization base station 20 and guide plate body 10, for holding osteotomy saw blade when osteotomy, plays the effect of positioning and directing.Osteotomy groove 30 inner surface is smooth structure.
Being positioned on the side of depth localization base station 20 on guide plate body 10 at least provided with a prominent cylindrical structure 41, hole 40, location is opened in the center of cylindrical structure 41. In the present embodiment, cylindrical structure 41 and hole 40, location are all only provided with one, if patient affected part area is excessive, it is possible to arrange multiple cylindrical structure 41 and hole 40, location. Hole 40, location and titanium nail with the use of, be used for preventing the free guide plate of individuation hip joint from sliding in osteotomy process. The centrage in hole 40, location is parallel with the longitudinal section of osteotomy groove.
The present invention further provides the manufacture method of the free guide plate of a kind of individuation hip joint, the manufacture method of the free guide plate of this individuation hip joint comprises the following steps:
1) hip joint of patient is carried out three dimensional CT (ComputedTomography, x-ray computer tomography) scanning, the data obtained saves as file 1 with Dicom (DigitalImagingandCommunicationsinMedicine, digital imaging and communications in medicine) form.
2) file 1 imports 3D rendering generate and editing and processing software, generate preliminary three-dimensional digitalization model, save as file 2 with STL (Stereolithography, stereolithography art) form.
3) file 2 is imported reverse engineering software, according to the design data of file 2 imported go out with patient's hip joint osteotomy line around the free guide plate of sclerotin form fit, and determine the depth localization base station of free guide plate, osteotomy groove and position position and the size in hole, save as file 3 with STL form. The manufacture method of free guide plate is: tentatively produce the physical model of free guide plate according to the data of file 2, carry out boolean's difference operation again through the hip joint affected part with patient, then produce with patient's hip joint osteotomy line around the free guide plate of sclerotin form fit.
4) file 3 is imported 3D printer, print the free guide plate of individuation hip joint of patient.
The free guide plate of whole individuation hip joint is formed in one structure, uses 3D printing technique to manufacture.
When the hip joint affected part of patient is treated, first patient affected part is carried out three-D CT scanning, generated by 3D rendering and three-dimensional digitalization model that editing and processing Software Create is preliminary, it is then introduced into reverse engineering software, according to the design data imported go out with patient's hip joint osteotomy line around the free guide plate of sclerotin form fit, and determine the depth localization base station of free guide plate, osteotomy groove and position position and the size in hole, the free guide plate of individuation hip joint of patient is printed finally by 3D printer.
During operation, the medial surface of the guide plate body 10 of free for individuation hip joint guide plate is fitted in patient affected part, titanium nail is embedded in hole 40, location, fix the free guide plate of individuation hip joint, it is prevented that it slides in osteotomy process. Then inserting in osteotomy groove 30 by osteotomy saw blade, the position that saw blade designs is installed limited block, during osteotomy, limited block contacts on depth localization base station 30, limits doctor's degree of depth when osteotomy.
Implement the embodiment of the present invention, have the advantages that the free guide plate of individuation hip joint of the present invention adopts 3D printing technique to be made, can fit with the perfection of patient affected part, and the depth of cut of surgical knife tool can be controlled when operation, avoid and after being blocked by sclerotin, injure blood vessel or nerve, be effectively controlled operation risk.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all within the spirit and principles in the present invention, any amendment of making, equivalent replacement, improvement etc., should be included within protection scope of the present invention.
