Abstract
The utility model discloses a snail type metal cup of an acetabulum prosthesis, which comprises a cup opening. A barb-shaped projection which is opposite to the cup opening is arranged on the surface of the outer circumference of the metal cup. The snail type metal cup of an acetabulum prosthesis of the utility model is directly driven into the acetabulum of a human body through a tool, with simple operation; damage to the intensity of the acetabulum can be reduced; owing to the function of a barb arranged on the surface of the outer circumference of the metal cup, the metal cup has firm fixing effects.
Description
Technical field
This utility model relates to a kind of medical artificial hip prosthesis, particularly relates to a kind of metal cup of oncomelania type acetabular component.
Background technology
After the human hip necrosis, can substitute downright bad part by the implantable artificial hip prosthesis and treat, the metal cup of manual acetabulum prosthese need be fixed on the hipbone of human body during operation.For metal cup is fixedly secured on bone, present metal cup generally is by the surface at its excircle screw thread to be set, and utilizes other instruments by the installing hole on the metal cup, and metal cup is screwed in the groove of offering on bone.This screw thread mounting means, it is very loaded down with trivial details to cause the doctor to operate, and in use for some time, is easy to generate loosening phenomenon between metal cup and the acetabular bone.
The utility model content
The purpose of this utility model is exactly a kind of simple installation will be provided and can make metal cup combine the metal cup of more firm oncomelania type acetabular component with hipbone.
To achieve these goals, the metal cup of a kind of oncomelania type of this utility model acetabular component comprises rim of a cup, and the external peripheral surface of described metal cup is provided with the projection with respect to the agnail shape of described rim of a cup.
Further, described projection on the outer circumference surface of described metal cup, form at least one with the co-axial round bulge loop of this metal cup.
Further, the quantity of described round bulge loop is twice.
Further, it is identical to constitute the described projection of the same round bulge loop circumferential distance between adjacent.
Further, the quantity of the projection on the round bulge loop of described per pass is identical.
Further, the outer circumference surface of described metal cup is provided with numerous rough pockmark.
Compared with prior art, the metal cup of a kind of oncomelania type of this utility model acetabular component is directly squeezed in the human body acetabular bone by instrument, and is simple to operate, reduced the damage of metal cup to human body acetabular bone intensity; Because the agnail effect that is provided with on the external peripheral surface of metal cup makes that the fixed effect of metal cup is more firm.
Description of drawings
Fig. 1 is the front view of the metal cup of this utility model oncomelania type acetabular component;
Fig. 2 is the vertical view of the metal cup of this utility model oncomelania type acetabular component;
Fig. 3 is the upward view of the metal cup of this utility model oncomelania type acetabular component.
The specific embodiment
Among Fig. 1-3, the metal cup of oncomelania type acetabular component, comprise the rim of a cup 1 and the cup end 6, several projectioies 2 are set near the external peripheral surface the rim of a cup 1 of metal cup, projection 2 has sharp wedge angle, rim of a cup 1 with respect to metal cup, projection 2 is the agnail shape, it is the direction that the wedge angle of each agnail is partial to rim of a cup 1, all projectioies 2 are formed the bulge loop 3 and the bulge loop 4 of twice and metal cup dead in line, circumferential lengths between the adjacent projection 2 is all identical, and the quantity of the projection 2 on bulge loop 3 and the bulge loop 4 is also identical.On the external peripheral surface of metal cup, also be provided with numerous rough tiny pockmark 5.
During operation, the doctor can utilize special instrument to knock this metal cup, metal cup is directly squeezed in the groove of treated human body acetabular bone.Compare with screw-in metal cup in the market, the projection 2 of agnail shape is set when the outer surface at metal cup after, metal cup easier for installation quick, and reduce the damage that acetabular bone intensity is produced; In addition, since the groove of the cup end 6 in acetabular bone of metal cup, the reversed acanthoid projection 2 on the metal cup outer surface, and nature can stop metal cup to move to the direction of rim of a cup 1, make metal cup be securely fixed in more in the acetabular bone, guaranteed that the service time of metal cup is longer.On the outer surface of metal cup, utilize the annular knurl blasting treatment after, form numerous rough tiny pockmark 5 thereon, form the micropore effect, this structure, in metal cup is embedded in acetabular bone after, be beneficial to very much the growth of bone, help the rehabilitation of human body.
Claims (6)
1, a kind of metal cup of oncomelania type acetabular component comprises rim of a cup, it is characterized in that, the external peripheral surface of described metal cup is provided with the projection with respect to the agnail shape of described rim of a cup.
2, the metal cup of oncomelania type acetabular component according to claim 1 is characterized in that, described projection on the outer circumference surface of described metal cup, form at least one with the co-axial round bulge loop of this metal cup.
