Description
Technical field
This utility model relates to a kind of medical rehabilitation instrument, more specifically, relates to a kind of artificial hip joint mortar cup.
Background technology
Replacement of Hip Joint is one of significant medical invention having obtained extensive clinical practice since the sixties in 20th century.A major part of artificial joint prosthesis is cotyla cup.The outside of cotyla cup and the fixing stability not only affecting joint of pelvis, also affect the transmission of joint load, stress stops and long-term clinical effectiveness.And the inner surface of cotyla cup directly and femoral head combine the sliding surface that forms hip joint affect joint motion and because rub, to wear and tear etc. and bring bad biological effect.The design of modern artificial hip cotyle cup is roughly divided into two classes, the first is single-body type, general employing cement reaction, most typical is Charnley hip cotyle cup system (HartofilakidisGC, Lampropoulou-AdamidouKI, StathopoulosIP, VlamisJA.TheOutcomeof241CharnleyTotalHipArthroplastiesPe rformedbyOneSurgeon30to40YearsAgo.JArthroplasty.2015Apr2 4.pii:S0883-5403 (15) 00297-1.doi:10.1016/j.arth.2015.04.018. [Epubaheadofprint]).The second is knockdown hip cotyle cup system, primarily of a metal outer cup and a mortar cup liner composition, generally fix (RiesMD.Reviewoftheevolutionofthecementlessacetabularcup. Orthopedics.2008Dec by biotype; 31 (12Suppl2) .pii:orthosupersite.com/view.asp? rID=37178.Review).The design of the first mortar cup has the advantages such as the low and long term clinical results of cost is not poor, but is unfavorable for that doctor is to the selection in different patients clinical.The second can solve the first Clinical practice problem, but bring other clinical problem thereupon, comprise the release of metal ion, stress stops, (the AgneMT such as the fretting wear problem of outer cup and liner, UnderwoodRJ, KocagozSB, MacDonaldDW, DayJS, ParviziJ, KraayMJ, MontMA, KleinGR, CatesHE, KurtzSM.IstheremateriallossatthebacksidetaperinmodularCo Cracetabularliners?
