Abstract
The utility model relates to a clamping-ring type acetabulum metal cup which is composed of an acetabulum metal cup main body, a clamping ring and an acetabulum metal cup lining. The acetabulum metal cup main body is in a hemispherical structure, some tack holes are formed in the hemispherical structure, and the acetabulum metal cup main body is connected with a human body acetabular fossa through the tack holes in the hemispherical structure in a fixing nail mode. The interior of the acetabulum metal cup main body is an inner cone type cavity, wherein a groove is formed in the inner edge of an opening of the cone type cavity, and the clamping ring is clamped in the groove. A ball fossa is arranged inside the acetabulum metal cup lining, and an outer cone structure is arranged outside the acetabulum metal cup lining. A groove is formed in the outer edge of the outer cone structure. The acetabulum metal cup lining and the acetabulum metal cup main body are fixed through match of the inner cone-shaped cavity and the outer cone-shaped structure. After the acetabulum metal cup lining and the acetabulum metal cup main body are fixed in a coned and matched mode, a locking purpose is achieved through the fact that the clamping ring is clamped in the inner groove of the inner cone-shaped cavity and the outer groove of the outer cone-shaped structure at the same time. The fixed structure has strong safety, and the acetabulum metal cup main body and the acetabulum metal cup lining cannot be accidentally separated after being locked. According to the clamping-ring type acetabulum metal cup, the acetabulum metal cup main body is made of titanium alloy materials, the clamping ring is made of the titanium alloy materials or stainless materials, and the acetabulum metal cup lining is made of ultra-high molecular weight polyethylene materials. Through match of the clamping-ring type acetabulum metal cup and a femoral stem prosthesis and a ball head, an surgical artificial hip joint hip arthroplasty of an implant can be finished.
Description
Technical field
This utility model relates to a kind of biological fixation type metal acetabulum cup, and it is applied to the biological fixation type total hip joint in the surgical implant artificial hip joint replacing.
Background technology
Replacement of Hip Joint is the Last Resort of the serious hip joint pathological changes for the treatment of, and the clinical acceptance rate more than 55 years reaches more than 85%.But in the artificial hip joint replacing operation, the metal acetabulum cup is fixing, and particularly fixing between metal acetabulum cup and metal acetabulum cup liner, be still the hot issue of clinical expert research.
In the hip prosthesis replacement operation, after metal acetabulum cup and human pelvis acetabular fossa are fixing, the connection of will be connected with the metal acetabulum cup and can not becoming flexible and deviate from when all needing metal acetabulum cup liner to install.When present stage, metal acetabulum cup liner was in being installed to the metal acetabulum cup, the fixed form that has often only adopted Small Taper to coordinate, although be also a kind of lock mode, not firm and safety.Common metal acetabular cup and metal acetabulum cup liner do not carry out particular design to it at joint face, and this produces some uncertain factors after just having caused it to install, and metal acetabulum cup and metal acetabulum cup liner have the risk of disengagement after surgery.
Therefore, how can allow the metal acetabulum cup is connected with metal acetabulum cup liner, effective, safe connection, be to need the target constantly pursued in hip replacement.
The utility model content
This utility model is different from common metal acetabular cup and metal acetabulum cup liner, and it provides a kind of snap ring-type acetabular bone metal cup of brand-new design.It can make and connect simple and convenient, effective and safety between metal acetabulum cup and metal acetabulum cup liner.
This utility model has been taked following design:
A kind of snap ring-type acetabular bone metal cup, it is comprised of acetabular bone metal cup main body, snap ring and acetabular bone metal cup liner three parts.Acetabular bone metal cup main body is hemispherical dome structure, has some to follow closely the hole on hemispherical dome structure, and acetabular bone metal cup main body adopts the form of staple to be connected with the human body acetabular fossa by the nail hole on hemispherical dome structure.Be tapered cavity in acetabular bone metal cup main body, along having a groove, in groove, card has snap ring in the opening of tapered cavity.There is a ball-and-socket acetabular bone metal cup liner inside, and the outside is an Outer Taper structure, and there is a groove outer of Outer Taper structure.Acetabular bone metal cup liner and acetabular bone metal cup main body being fixed by inside and outside tapering part.Acetabular bone metal cup liner and acetabular bone metal cup main body cone join fixing after, snap in simultaneously by snap ring the purpose that interior tapered cavity inside groove and Outer Taper water jacket reach locking.This kind fixed structure has very strong safety, can unexpected not separate after the locking of acetabular bone metal cup main body and acetabular bone metal cup liner.A kind of snap ring-type acetabular bone of this utility model metal cup, acetabular bone metal cup main body are that titanium alloy material is made, and snap ring is that titanium alloy or stainless steel material are made, and acetabular bone metal cup liner is that superhigh molecular weight polyethylene material is manufactured.This utility model coordinates type femoral bone end prosthesis and bulb, can complete surgical implant artificial hip joint total hip joint.
The utility model has the advantages that:
1, a kind of snap ring-type acetabular bone of this utility model metal cup, when acetabular bone metal cup main body and acetabular bone metal cup liner adopt Small Taper to coordinate, unique design the snap ring locking structure, guarantee can not separate after locking between acetabular bone metal cup main body and acetabular bone metal cup liner.
2, a kind of snap ring-type acetabular bone of this utility model metal cup, acetabular bone metal cup main body can adopt instrument with its safe separating with acetabular bone metal cup liner, does not exist when need separating and the risk that can not separate.
