Abstract
The utility model discloses an improved whole-acetabulum metal outer cup and plastic liner of artificial hip joint which is characterized in that a conjugated surface of a metal outer cup and a plastic liner of the whole acetabulum is processed into an inner-cone surface and an outer-cone surface, and is assembled according to the wimble angle. The conjufaged surface is less liable to micro movement, rotation and breaking off, which eliminates the physiological burden of patients. The utility model is applicable to the hip bone replacement surgery for the hip joint disease.
Description
Affiliated technical field
This utility model relates to the artificial joint of medical domain.The full hip metal of particularly a kind of improved artificial hip joint acetabular bone.
Background technology
The full hip metal of artificial hip joint acetabular bone is a body implant, the alternative of implant into body hip joint when being used for the human hip pathological changes and need carrying out the orthopaedics replacement operation, make patient recover the physiological function of hip joint to a certain extent, alleviating pain improves motion and improves the quality of living.In prior art, the outer cup of the metal of full hip metal acetabular bone is to adopt to screw in assembly structure with the plastic inner lining assembling, easily produces fine motion and rotation, has increased the mortality of replacement, increases the weight of patient's physiological load.
Summary of the invention
The purpose of this utility model is to provide outer cup of the full hip metal of a kind of improved artificial hip joint acetabular bone metal and plastic inner lining, can overcome the outer cup of existing artificial hip joint metal and produce the defective of fine motion and rotation because of assembly structure is unreasonable with plastic inner lining.
Task of the present utility model realizes by this way: the full hip metal of this artificial hip joint acetabular bone is made up of with plastic inner lining the outer cup of metal.It is characterized in that outer glass of mating surface with plastic inner lining of the metal of full hip metal acetabular bone is processed into inner conical surface and male cone (strobilus masculinus) respectively.
From above-mentioned improvement as can be known, because outer glass of mating surface with plastic inner lining of the metal of full hip metal acetabular bone is processed into inner conical surface and male cone (strobilus masculinus) respectively, the application of force is pressed into plastic inner lining in the outer cup of metal in the assembling, forms taper fit, makes it not produce fine motion, rotates and comes off.
When implementing this utility model, the outer cup of the metal of described full hip metal acetabular bone is processed into inner conical surface and male cone (strobilus masculinus) respectively with the mating surface of plastic inner lining, and the interference fit tapering is: 0.1～179 degree.
Description of drawings
Fig. 1: be the sketch map of a kind of concrete structure of this utility model
The specific embodiment
As shown in the figure: this utility model be made up of outer cup 1 of the metal of full hip metal acetabular bone and plastic inner lining 2 and the physical dimension of the full hip metal of existing artificial hip joint acetabular bone are basic identical, and the implantation mode is identical.Its difference is: the outer cup of the metal of full hip metal acetabular bone is to adopt the interference fit of mating surface tapering to form with the plastic inner lining assembling, and the interference fit tapering is: 6 degree; The outer cup 1 of metal adopts the smart casting of the metal vacuum that can plant human body or forges and make, and inner conical surface adopts machining process to obtain; Plastic inner lining 2 adopts medical superhigh molecular weight polyethylene material mold pressing or extrudes and make, and male cone (strobilus masculinus) adopts machining process to make.
Claims (2)
1, the full hip metal of a kind of artificial hip joint acetabular bone includes the outer cup of metal (1) and plastic inner lining (2), it is characterized in that the mating surface of (1) and (2) is processed into inner conical surface and male cone (strobilus masculinus) respectively, and assembling adopts tapering to be press-fitted.
2, the full hip metal of artificial hip joint according to claim 1 acetabular bone, the outer cup (1) and the plastic inner lining (2) of the described full hip metal acetabular bone of its feature are processed into inner conical surface and male cone (strobilus masculinus), and the interference fit tapering is 0.1～179 degree.
