Abstract
The invention discloses a biological fixation type tibia platform for surgery implants. The biological fixation type tibia platform is composed of a platform body and an intramedullary rod. A biological coating adheres to the lower surface of the platform body, and thorn-shaped protrusions are arranged on the platform body which facilitates initial fixation of the platform. The intramedullary rod is connected with the platform through a conical structure, the biological coating adheres to the upper portion of the intramedullary rod, and spine-shaped structures which are evenly distributed are arranged on the columnar face of the lower portion of the intramedullary rod. A prosthesis can be conveniently inserted into the bone, meanwhile, the anti-rotation function is provided, and the biological fixation type tibia platform can still be firmly fixed under the action of rotation force. The biological fixation type tibia platform can provide immediate fixation after an operation, the good anti-rotation function is achieved, and due to different combination modes, the biological fixation type tibia platform meets the requirements of different patients.
Description
Technical field
The present invention relates to a kind of clinical medicine surgical technic field, a kind of surgical implant prosthese specifically, a kind of implant for knee joint surface replacement, particularly relates to a kind of biological fixation type tibial plateau.
Background technology
Knee joint is one of the large joint of the lower limb of human body, and knee joint osteoarthritis is also old people's commonly encountered diseases, frequently-occurring disease.Because wearing and tearing or the regression meeting of articular cartilage causes arthralgia, knee joint endoprosthesis replacement, the most frequently used is exactly surface replacement art, exactly cartilage and the subchondral bone of kneed femur and tibia wearing and tearing are reamed to skim, then with bone cement or directly the metal implant of vitallium is fixed to osteotomy surface, the parts that substitute femur side seam matter are called condyle of femur, the parts that substitute tibial side sclerotin are called tibial plateau, in the middle of condyle of femur and tibial plateau, lining, with polyethylene pads, plays the effect that reduces friction, recovers knee joint function.At present, most knee joint adopts bone cement fixed form, but in fact, bone cement itself also exists some defects really, produces some complication, as bone cement chip can cause prosthetic loosening, is unfavorable for further overhauling etc.Therefore advise that the good patient of young, sclerotin should first-selected biological fixation.The design philosophy of biological fixation type prosthese is to coordinate and the osseous tissue prosthetic surface of growing into reaches the effect of biological fixation by pressing.
