Description
Technical field
The present invention relates to a kind of femoral head prosthesis, particularly relating to a kind of for repairing necrosis, the capital repairing module of collapsed portion.
Background technology
Femoral head prosthesis is the surgical implant of human body femoral hip prosthesis head part, for necrosis, the femoral head that subsides repairs, use as excessive joint.
Existing femoral head prosthesis has progressive, but but finds also there is some shortcomings in its structure when reality uses, and causes this femoral head prosthesis to have limitation.
Summary of the invention
The object of the present invention is to provide a kind of fixation, the repairing module of femur head necrosis collapsed portion can be repaired.
For achieving the above object, the concrete technical scheme of the manufacture method of a kind of applying three-dimensional printing technique of the present invention customized femur head necrosis repairing module is:
The customized femur head necrosis of applying three-dimensional printing technique repairs a manufacture method for module, and the method comprises the steps:
Computed tomography reconstruction is carried out to sufferer femoral head, the solid figure of computer is produced femoral head prosthesis model, to simulate the capital situation of sufferer on femoral head prosthesis model;
Downright bad collapsed portion in excision femoral head prosthesis model;
According to the capital bone portion 3-D view of sufferer obtained after the downright bad collapsed portion of excision and sclerotin border, produce for filling up the capital repairing module of the downright bad collapsed portion of sufferer;
Three-dimensional printer is used to print repairing module;
Wherein, the material repairing module can adopt titanium alloy material or polythene material.
A kind of femur head necrosis repairs module, femoral head prosthesis simulates for filling up the capital repairing module of the downright bad collapsed portion of sufferer, repairing module is wedge shape, and the side of femoral head prosthesis is bone trabecula, bone trabecula contacts with femoral head, and femoral head bone can be grown into and be repaired in module; The outer surface of femoral head prosthesis is burnishing surface, in case friction and wear causes producing granule.
The advantage that the customized femur head necrosis of a kind of applying three-dimensional printing technique of the present invention repairs the manufacture method of module is:
1) there is good wearability and biocompatibility;
2) fixed by Embedded agnail and screw, there is good stability;
3) surface forms burnishing surface by polishing, reduces the generation of abrasion and wear particle;
4) joint contact face is trabecular bone structure, adds roughness, is convenient to osteogenesis;
5) CT scan data can be utilized to carry out customized according to downright bad collapsed portion femoral head to the shape of repairing module, make the repairing module prosthese highly meeting sufferer;
6) overcome the present situation that existing femur head necrosis needs to replace a set of hip joint, do not need femoral stem and full acetabular bone.
Accompanying drawing explanation
Fig. 1 is the structural representation of repairing module of the present invention;
Fig. 2 is the left view of the repairing module in Fig. 1.
Detailed description of the invention
In order to better understand object of the present invention, structure and function, below in conjunction with accompanying drawing, the manufacture method of the customized femur head necrosis of a kind of applying three-dimensional printing technique of the present invention being repaired to module does further detailed description.
As depicted in figs. 1 and 2, it shows the manufacture method for a kind of applying three-dimensional printing technique of the present invention customized femur head necrosis repairing module, the sufferer of 50% can be less than for necrotic extent in femur head necrosis, the method comprises the steps: to carry out computed tomography reconstruction (being CT scan to rebuild) to the femoral head of sufferer, be made into CD, technician produces the femoral head prosthesis model with necroses of 1:1 equal proportion in the solid figure of computer, to simulate the capital situation of sufferer on femoral head prosthesis model; Downright bad collapsed portion in femoral head prosthesis model on Computerized 3 D figure is carried out wedge excision; According to the capital bone portion 3-D view of sufferer obtained after the downright bad collapsed portion of excision and sclerotin border, produce for filling up the capital repairing module of the downright bad collapsed portion of sufferer; Repairing module is printed by three-dimensional printer (i.e. 3D printer) after software conversion; Repairing module is fixed on sufferer femoral head.Wherein, the present invention uses 3 D-printing (namely 3D prints) technology to produce the downright bad collapsed portion of the sufferer capital repairing module prosthese of equal proportion according to the ratio of 1:1.
The material of the repairing module in the present invention can adopt titanium alloy material, make for employing titanium alloy material and fill the capital repairing module of sufferer, the both sides of repairing module are provided with fixing hole, and fixture is passed by fixing hole and repairs module to insert repairing module on the femoral head of sufferer.To repair the surface finish of module, and arrange multiple micropore in the two sides of repairing module, sufferer femoral head bone can be grown into and be repaired in module with together with repairing module being fixedly secured with femoral head.Wherein, tiltedly passed from inside to outside, upward by fixture and repair module with retained prosthesis makes module, fixture can adopt screw, but is not limited in use screw.
The material of the repairing module in the present invention can adopt polythene material, makes fill the capital repairing module of sufferer for employing polythene material, repairs module and injects repairing module to be fixed on the femoral head of sufferer by bone cement.
Repairing module 1 of the present invention is in wedge shape, repairing the two sides that module 1 contacts with sufferer joint is bone trabecula 4, bone trabecula has micropore, add the roughness of femoral head prosthesis 1, after contacting with femoral head, femoral head bone can be grown into and be repaired in module, to repair the Bone Ingrowth of module thus to realize being permanently fixed; The outer surface of femoral head prosthesis 4 is burnishing surface 3, in case friction and wear causes producing granule.
Further, the outer end face repairing module 1 is provided with multiple protruding 2, and protruding 2 can insert on femoral head with retained prosthesis makes module 1.
Further, the side of repairing module 1 is provided with fixing hole 5, and fixing hole 5 is the through hole on bone trabecula, and repairing module 1 can be fixed on femoral head through fixing hole 5 by fixture, to be inserted in femoral head by stable for projection, has good stability.Wherein, fixture can be screw, and repairing module is fixed in femoral head through fixing hole by screw.
In addition, projection 2 is cylindrical, and multiple protruding 2 arranged in parallel being arranged on are repaired in module 1, and the length of two adjacent projections 2 is not identical.
Further, the shape of repairing module 1 can utilize CT scan data to customize, make before surgery and meet the downright bad collapsed portion of sufferer capital repairing module prosthese, by collapsed portion femoral head excision downright bad in femoral head, retain the good femoral head that pathological changes does not occur, then repairing module prosthese is fit in the good femoral head of sufferer.
The customized femur head necrosis of applying three-dimensional printing technique of the present invention repairs the manufacture method of module, has good wearability and biocompatibility; Fixed by Embedded agnail and screw, there is good stability; Surface forms burnishing surface by polishing, reduces the generation of abrasion and wear particle; Joint contact face is trabecular bone structure, adds roughness, is convenient to osteogenesis; CT scan data can be utilized to carry out customized according to downright bad collapsed portion femoral head to the shape of repairing module, make and highly meet sufferer capital repairing module prosthese; Overcome the present situation that existing femur head necrosis needs to replace a set of hip joint, do not need femoral stem and full acetabular bone.
