The elbow joint that the reasons such as wet, bone tumour are destroyed, and substituted with artificial prosthesis, it is finally reached pain of alleviation and saves part elbow joint
The purpose of function.According to statistics, Orthopedic Aseptic Operation postoperative infection rate is about 3%, and open wound infection rate after abortion operation is 10-20%,
After artificial joint replacement, deep infection rate, large case is 1.6-2.5%.Most common artificial elbow in present clinical practice
Articular prosthesis is entirely limited type prosthese and certain non-limiting examples prosthese for non-antibacterial, is realized in art mainly by implantation antibacterial bone cement
The antibacterial of prosthese, antibacterial time is short, and effect is undesirable.Most common complication is as caused by infection after this kind of prosthetic replacement
Prosthetic loosening, abrasion and unstable (subluxation or dislocation), ancon bony structure is relatively complicated and soft tissue covering is less,
It is more by the nervus vasculairs of ancon, previously carry out Repeated Operation or serious condition be present, artificial total elbow joint replacement
For complication apparently higher than full hip, knee replacement art, revision rate also will height, it can be seen that joint replacement postoperative infection will be for patient
It is catastrophic, therefore it is particularly important to design a all new generation anatomical form antibacterial elbow joint.
Therefore, this patent makes it have 5 ° -10 ° in coronal-plane using disconnecting preventing bit architecture design " loose hinge " design
Angular relaxation, caused rotation and the interior stress that turns up can be distributed to surrounding soft tissue during bending and stretching, and reduce prosthese interface
Stress, while prosthese carries physiological curvature, prosthese is more met the anatomical features of human body.Prosthese humeral component and ulna
Parts surface is sprayed with the titanium micropore antimicrobial coating of copper ions, and after it is contacted in human body with oxide isolations such as body fluid,
The titanium micro porous coating of copper ions will gradually be oxidized and discharge copper ion, when micro copper ion reaches microbial cell film
When, because cell membrane carries negative electrical charge, copper ion can rely on Coulomb force first, and firmly absorption on cell membrane, then penetrates further into
Cell membrane enters in germ, contains with sulfydryl (- SH) present in the protein in germ organism, nucleic acid, nitrogen base (- NH2) etc.
Sulphur, the functional group of ammonia react, and make the protein coagulating of germ, destroy the activity of the cell synzyme of germ, lose cell
Lose points and split multiplication capacity and finally wither away, so as to reach antibacterial and reduce or eliminate the mesh of artificial joint prosthesis infections relating generation
's.
