Description
Technical field
This utility model belongs to artificial joint technical field, is specifically related to a kind of compound mortar cup.
Background technology
In order to treat the diseases such as ankylosis, joint deformity and various destructive osteoarthrosis, 1962, Charnley forms artificial joint ultra-high molecular weight polyethylene and cochrome, and fix with bone cement (methacrylate), it is applied to human body, since then, artificial joint replacement enters the new stage of reality application.In the history more than 50 years, arthroplasty has developed into a kind of method that the damage of current clinical treatment severe joint is best with joint failure curative effect.It is reported, there are about 30,000,000 people what China needed to carry out prosthetic replacement, owing to human synovial function is complicated, particularly there is the mobility of multiple directions, and bear and certain draw, press, roll over, the load such as bend, so the selection to material property requires the highest.Such as: hip joint is made up of ball and socket joint and glenoid fossa, for connecting the glenoid fossa of femoral head and pelvis.Replacement of total hip includes three parts: 1. with ultra-high molecular weight polyethylene glenoid fossa replacement hip joints nest；2. with the femoral head of metal joint head displacement fragmentation；3. insert femoral shaft by metallic rod and increase the stability of artificial joint.Generally connect the metallic rod of femur and be cochrome or titanium alloy material is made, the sphere on the femur top inserting hip joint nest is then made up of cochrome or refined alumina ceramic material, hip joint nest is by ultra-high molecular weight polyethylene liner press-in mortar cup, use titanium alloy material to make more mortar cup, by the method being fixed with pressure, mortar cup is implanted pelvis.Clinical research shows, effective length of service of artificial joint based on materials such as ultra-high molecular weight polyethylenes implantation human body is 10 ~ 15 years.In bio-medical material, compared with pottery and macromolecular material, medical titanium alloy, due to resistance to compression and tensile strength height, the excellent physical and chemical performance such as biocompatibility is good, reliability is high, is widely used in the implantation instrument such as dentistry, orthopaedics.Surrounding tissue is in use easily caused damage by existing bone socket cup, and fixed effect is bad.
Utility model content
The purpose of this utility model is to provide a kind of simple in construction, is fixed easily and the compound mortar cup of length in service life.
For achieving the above object, this utility model is by the following technical solutions: one is combined mortar cup, including the ball and socket joint with implant, is provided with liner outside ball and socket joint, and liner is externally provided with metal acetabular cup, is covered with diamond alkene layer outside metal acetabular cup；Being evenly equipped with cone boss on diamond alkene layer, cone boss top end face caves inward；Metal acetabular cup is provided with through hole, and through hole runs through diamond alkene layer；Diamond alkene layer is made up of the nanometer diamond alkene of lamellar mono-crystalline structures；It is that sp3 orbital hybridization carbon bond connects between the carbon atom of the same lamella of nanometer diamond alkene of lamellar mono-crystalline structures, is that sp2 hydridization carbon bond connects between carbon atom between layers；The spacing of lattice of nanometer diamond alkene is 0.21nm；The mean diameter of nanometer diamond alkene is R, 20≤R≤300nm；The C content of nanometer diamond alkene is 99～100%.
Further, cone boss is integrated with diamond alkene layer.
Further, the width of cone boss bottom face is 0.8-1mm, and the inclined-plane of cone boss and the angle of centrage are 45 °-60 °, and the height of cone boss is 0.1-0.2mm.
Further, diamond alkene layer aligns with metal acetabular cup.
Further, diamond alkene layer is 0.4-0.6mm.
Compared with prior art, the beneficial effects of the utility model are as follows: be covered with diamond alkene layer outside metal acetabular cup, diamond alkene layer is set and can improve the wearability of mortar cup, corrosion resistance and biocompatibility, improve the service life of compound mortar cup and surrounding tissue will not be damaged；It is evenly equipped with cone boss on diamond alkene layer, cone boss is set and can improve the tightness that compound mortar cup is connected with pelvis, and cone boss top end face caves inward, contact surface can be firmly grasped, strengthen fixed effect；Metal acetabular cup is provided with through hole, and through hole runs through diamond alkene layer, uses screw to be fixed on pelvis by compound mortar cup, prevents from coming off or sliding；Cone boss is integrated with diamond alkene layer, reduces difficulty of processing and strengthens the stability of overall performance；The width of cone boss bottom face is 0.8-1mm, and the inclined-plane of cone boss and the angle of centrage are 45 °-60 °, and the height of cone boss is 0.1-0.2mm, reduces the impact of form original on mortar cup, strengthens fixed effect；Diamond alkene layer aligns with metal acetabular cup, keeps original shape, reduces the impact on surrounding tissue.
