Abstract

The invention discloses a kind of preparation method of integral type acetabular component, including：It is made up of metal outer cup and outer cup liner, first prepares metal outer cup using various processing methods, then outer cup liner is constructed on metal outer cup body by increases material manufacturing technology.One-shot forming integral type acetabular component, makes accurate combination between the two, fine motion is reduced, so as to reduce abrasion, reduces machining processes, advantageously reduce cost.

Description

A kind of integral type acetabular component and preparation method thereof
Technical field
The present invention relates to technical field of medical instruments, more particularly to a kind of orthopaedics implant integral type acetabular component and its system Preparation Method.
Background technology
The joint prosthesis disease caused by disease and wound is common disease clinically, is also the worldwide difficulty of orthopaedics therapy One of topic, severely impacts the quality of life of patient.Metal outer cup and outer cup liner are that current clinic should as acetabular component With more universal orthopaedics material.Extensive use of the acetabular component in orthopaedics therapy, the clinic of significantly improving over can not The problem of solution and it is implanted to power and has also reached quite satisfied effect.Current metal outer cup is independent with outer cup liner Processing, independent packaging need to be carried out after both cooperations, implantation human body by operation technique, between metal outer cup and outer cup liner Interface can produce fine motion, so as to produce abrasive dust, cause Using prosthesis to fail, and processing cost is higher.And we are in metal Directly construct outer cup liner on outer cup body by increases material manufacturing technology, form the acetabular component of integral type, metal outer cup and outer Accurate between cup liner to combine, fine motion is reduced, so that abrasion is reduced, while the reduction of machining processes further saves production Cost.
The content of the invention
The technical problems to be solved by the invention are the defects for overcoming above-mentioned prior art, and we use increases material manufacturing technology Outer cup liner is directly constructed on metal outer cup, is conducive to the precision-fit of metal outer cup and outer cup liner, is added while reducing Work process, saves cost.
The technical problems to be solved by the invention are achieved by the following technical programs：
A kind of preparation method of integral type acetabular component, including：It is made up of metal outer cup and outer cup liner, first uses various processing Method prepares metal outer cup, then outer cup liner is constructed on metal outer cup body by increases material manufacturing technology.
Further, the increases material manufacturing technology is 3D printing.
Further, the outer cup liner is made up of the high polymer material 3D printing of biocompatibility.
Further, metal outer cup material therefor is the metal material of biocompatibility.
The present invention has the advantages that：
（1）One-shot forming integral type acetabular component of the present invention, outer cup is constructed directly on metal outer cup using increases material manufacturing technology Liner, makes accurate combination between the two, fine motion is reduced, so as to reduce abrasion, reduces machining processes, advantageously reduce cost.
（2）Process is simple, controllability is strong, easy to operate.
Brief description of the drawings
Fig. 1 is front view of the invention.
Fig. 2 is profile of the invention.
Embodiment
With reference to embodiment, the present invention will be described in detail, and embodiment is only the preferred embodiment of the present invention, It is not limitation of the invention.
In the preparation method of the integral type acetabular component of the present invention, first it is made using vacuum lost wax casting or forging outside metal Cup, then outer cup liner is constructed on metal outer cup body by increases material manufacturing technology.
The increases material manufacturing technology is preferred but is not limited to 3D printing.
The metal outer cup is preferred but is not limited to by the metal material vacuum lost wax casting of biocompatibility or forging It is made, wherein the metal material of biocompatibility is preferred but is not limited to titanium alloy, cochrome, and wherein titanium alloy includes Ti- 8Fe-8Ta-4Zr, Ti-8Fe-8Ta-4Zr greatly reduce modulus of elasticity compared to traditional titanium alloy, can obtain in machine Excellent results in terms of tool property and biocompatibility.
The outer cup liner is preferred but is not limited to be made up of the high polymer material 3D printing of biocompatibility, wherein raw The high polymer material of thing compatibility is preferred but is not limited to the materials such as ultra-high molecular weight polyethylene, high crosslinked ultra-high-molecular-weight polyethylene Material.
Embodiment 1
A kind of integral type acetabular component, its preparation method includes：Using titanium alloy material, manufactured by the mode of forging outside metal Cup, then the method printed using superhigh molecular weight polyethylene material by 3d are directly constructed in outer cup on outer cup liner body Lining.
Comparative example 1
A kind of acetabular component, respectively comprising metal outer cup and outer cup liner, its preparation method is：Using titanium alloy material, pass through Forging mode manufactures metal outer cup；Using superhigh molecular weight polyethylene material, outer cup liner is manufactured by machine-tooled method, the two For individual components.
Detection project:
A. wear test
Integral type acetabular component is worn and torn with common independent acetabular component according to ISO 14242-1 and ISO 14242-2 Experiment, both polishing machinees are judged by testing the wear extent of ultra-high molecular weight polyethylene.
B. cost accounting
Every cost such as machining cost in production whole process, cleaning cost, testing cost, cost of labor etc. are carried out Adjust, the similarities and differences of the contrast integral type acetabular component with common independent acetabular component in terms of cost.
Test result：
A:The wear extent of the integral type acetabular component of embodiment is less than the common independent acetabular component of comparative example.
B:Cost accounting shows that the cost of the integral type acetabular component of embodiment is relatively low, and overall cost advantage is obvious.
Embodiment described above only expresses embodiments of the present invention, and it describes more specific and detailed, but can not Therefore the limitation to the scope of the claims of the present invention is interpreted as, as long as the skill obtained using the form of equivalent substitution or equivalent transformation Art scheme, all should fall within the scope and spirit of the invention.
