Abstract
The invention discloses a kind of preparation method of integral type double motion head, including：It is made up of double motion head outer cup and double motion head liner, first prepares double motion head outer cup using various processing methods, double motion head liner is directly constructed using increases material manufacturing technology on double motion head outer cup body.One-shot forming integral type double motion head, makes accurate combination between the two, fine motion is reduced, so as to reduce abrasion, reduces machining processes, advantageously reduce cost.
Description
Technical field
The present invention relates to technical field of medical instruments, more particularly to a kind of orthopaedics implant integral type double motion head and its 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.Double motion head is current clinical practice more universal orthopaedics material.It is double
Dynamic extensive use of the head in orthopaedics therapy, significantly improves over and clinical insurmountable problem and is implanted to power also
Quite satisfied effect is reached.Current double motion head outer cup and double motion head liner is separately machined, after the completion of each automatically cleaning, passes through
Machining tool matches somebody with somebody outer cup and liner, is made after double motion head sub-assembly, implantation human body, between double motion head outer cup and double motion head 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 double motion head
Directly construct double motion head liner on outer cup body by increases material manufacturing technology, form the double motion head of integral type, double motion head outer cup and
Accurate between double motion head liner to combine, fine motion is reduced, so that abrasion is reduced, while the reduction of machining processes is further saved
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
Double motion head liner is directly constructed in double motion head outer cup, is conducive to the precision-fit of double motion head outer cup and double motion head liner, simultaneously
Manufacturing procedure is reduced, cost is saved.
The technical problems to be solved by the invention are achieved by the following technical programs：
A kind of preparation method of integral type double motion head, including：It is made up of, is first added using various double motion head outer cup and double motion head liner
Work method prepares double motion head outer cup, and double motion head liner is directly constructed using increases material manufacturing technology on double motion head outer cup body.
Further, the increases material manufacturing technology is 3D printing.
Further, the double motion head liner is made up of the high polymer material 3D printing of biocompatibility.
Further, the double motion head outer cup material therefor is the metal material of biocompatibility.
The present invention has the advantages that：
（1）One-shot forming integral type double motion head of the present invention, directly constructs double acting in double motion head outer cup using increases material manufacturing technology
Head liner, makes accurate combination between the two, fine motion is reduced, so as to reduce abrasion, reduces machining processes, advantageously reduce into
This.
（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

Material.
Embodiment 1
A kind of integral type double motion head, its preparation method includes：Using vitallium material, double motion head is manufactured by forging type
Outer cup, then the method printed using superhigh molecular weight polyethylene material by 3d directly construct double acting on double motion head outer cup body
Head liner.
Comparative example 1
A kind of double motion head, respectively comprising double motion head outer cup and double motion head liner, its preparation method is：Using vitallium material
Material, double motion head outer cup is manufactured by forging type；Using superhigh molecular weight polyethylene material, manufacture double acting by machine-tooled method
Head liner, after the completion of each self-cleaning, double motion head is assembled into by mach mode by the two.
Detection project:
A. wear test
Wear test is carried out to integral type double motion head and the double motion head commonly assembled according to ISO 14242-1 and ISO 14242-2,
Judge both polishing machinees 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, contrast the similarities and differences of integral type double motion head and the double motion head commonly assembled in terms of cost.
Test result：
A:The wear extent of the integral type double motion head of embodiment is less than the double motion head of the common assembling of comparative example.
B:Cost accounting shows that the cost of the integral type double motion head 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.
