Abstract
The utility model discloses an improved metal acetabulum outer cup of artificial hip joint which s characterized in that an external surface of a fundamental metal acetabulum outer cup is provided with heavy-head screw holes through which the metal acetabulum can be fixed on the born by bolts. The heavy-head screw holes prevent the movement and breaking off of the metal acetabulum, enhances the service life of the product and 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 outer cup of particularly a kind of improved artificial hip joint metal acetabular bone.
Background technology
The outer cup of artificial hip joint metal 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 quality of life.In prior art, the outer cup of metal acetabular bone is not with the sunk screw hole, has slightly and installs and improper use, may cause the outer cup of metal to become flexible, come off.Increase the mortality of replacement, increased the weight of patient's physiological load.
Summary of the invention
The purpose of this utility model is to provide a kind of improved artificial hip joint metal acetabular bone outer cup, can overcome the instability that the outer cup of existing artificial hip joint metal acetabular bone is installed, can reduce loosening, defective such as come off.
Task of the present utility model realizes by this way: the outer cup of this artificial joint metal acetabular bone comprises that outer cup in basis and sunk screw hole disjunctor form the outer cup of artificial hip joint metal acetabular bone, it is characterized in that a plurality of sunk screws of making hole on glass shell of cup the basis outside.
From above-mentioned improvement as can be known,, reach and directly to use screw and the fastening purpose of osseous tissue, reached good fixed effect owing to processed a plurality of sunk screws hole on the cup shell of cup outside.
When implementing this utility model, the quantity in described sunk screw hole is: 1～20; The diameter in hole is: 2～15 millimeters.The quantity in sunk screw hole is too much or diameter is excessive, the intensity of the outer cup of influence; The quantity in sunk screw hole is very few or diameter is too small, can cause fixed effect bad.
Description of drawings
Figure: be the sketch map of a kind of concrete structure of this utility model
The specific embodiment
As shown in the figure, glass specification is basic identical outward with existing artificial hip joint metal acetabular bone by cup 1 outside the basis and this utility model of forming of sunk screw hole 2 disjunctors.Its difference is processing sunk screw hole 2 on the basic outer cup shell of cup outside the metal acetabular bone, and quantity is: 3, and be distributed on the same latitude on the basic outer cup shell; The diameter of through hole is: 5.8 millimeters.The outer cup 1 in basis of the outer cup of this artificial hip joint metal acetabular bone adopts the smart casting of the metal vacuum that can plant human body to make, and also can adopt to forge and make; Screw counter sink 2 adopts machining to make.
Claims (2)
1, a kind of artificial hip joint metal acetabular bone, include cup outside the outer cup in basis (1), sunk screw hole (2) the disjunctor composition artificial hip joint metal acetabular bone, it is characterized in that outside artificial hip joint metal acetabular bone, processing several sunk screw holes (2) on the shell of glass (1) outside the cup basis.
2, the outer cup of artificial hip joint metal acetabular bone according to claim 1, the described sunk screw of its feature hole (2), quantity is: 1～20; The diameter of through hole is: 2～15 millimeters.
