Abstract
The invention provides an implant artificial hip joint stem which is characterized in that the surface of a proximal femur stem is in a bone trabecula form which is in a scalene triangle stereochemical structure. The voidage of the bone trabecula occupies 50-70% of the surface area of the bone trabecula, and the gap diameter of the scalene triangle stereochemical structure is 200-400 micrometers. The bone trabecula is completely connected with a femur stem main body. The bone trabecula and the femur stem main body are made of the same materials and are in an integral structure.
Description
Technical field
The present invention relates to the handle of the implanted femur near-end of hip joint in orthopedics's osteoarthrosis.
Background technology
Since the seventies in last century, due to the progress of artificial product technology, in developed country because degeneration and other bone lesion, joint replacement has become the most important measure for the treatment of, and progressively enlarging the use crowd, making the patient that incompetent movable basis arranged, the life-span is significant prolongation also; But hip joint is becoming flexible because of femoral stem often, cause using a period of time just need to carry out for the second time or displacement for the third time, the femoral stem of therefore inventing new artificial hip joint, make artificial femur handle become bone implantation body, closely merge with femur top, one on physiology reduces or eliminates because of the loosening of femoral stem replacement joint again, has become the medical problem of being badly in need of solution.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, the femoral stem part that proposes a kind of artificial hip joint can combine together fully with near end of thighbone, reach except violence causes fracture or handle body and rupture and need again replacement product, do not need throughout one's life because femoral stem is loosening implantation body's artificial hip joint stem of replacement joint again under other state and condition.
The present invention realizes in the following way: a kind of implantation body artificial hip joint stem, it is characterized in that, the nearly section surface of femoral stem is the bone trabecula form, described bone trabecula form is the sealene triangle stereochemical structure, bone trabecular voidage accounts for 50～70% of surface area, and between the space of structure, the footpath is 200～400 μ m; Bone trabecula is connected fully with the femoral stem main body, is the integrative-structure that uses same material to make.
A kind of implantation body artificial hip joint stem, it is characterized in that, the bone trabecula internal layer of femoral stem is the thick densified metal layer of 1～5mm, the top of femoral stem is to be connected with the artificial femur neck and the position of implant infrastructure, there is oval artificial femur neck mounting structure the inboard, the work connecting device that the promising artificial femur handle in the outside, top is installed and pulled out.
Beneficial effect of the present invention is, the nearly section surface of femoral stem is designed to the bone trabecula form of sealene triangle stereochemical structure, and bone trabecula and femoral stem main body are integrated; The bone trabecula internal layer is the thick densified metal layer of 1～5mm, is the main part of this femoral stem and main load-carrying members, and active force is delivered to the epimere of femur by the trabecular bone structure on surface; The femoral stem part can merge with the comprehensive three-dimensional of near end of thighbone, obtain concordance biology with bone, reach except violence causes fracture or handle body and rupture and need again replacement product, do not need throughout one's life because femoral stem is loosening the purpose of replacement joint again under other state and condition.

The specific embodiment
A kind of implantation body artificial hip joint stem, it is characterized in that, the bone trabecula internal layer of femoral stem is the thick densified metal layer of 1～5mm, the top of femoral stem is to be connected with the artificial femur neck and the position of implant infrastructure, there is oval artificial femur neck mounting structure the inboard, the work connecting device that the promising artificial femur handle in the outside, top is installed and pulled out.
Claims (2)
1. implantation body's artificial hip joint stem, it is characterized in that, the nearly section surface of femoral stem is the bone trabecula form, and described bone trabecula form is the sealene triangle stereochemical structure, bone trabecular voidage accounts for 50～70% of surface area, and between the space of structure, the footpath is 200～400 μ m; Bone trabecula is connected fully with the femoral stem main body, is the integrative-structure that uses same material to make.
2. a kind of implantation body according to claim 1 artificial hip joint stem, it is characterized in that, the bone trabecula internal layer of femoral stem is the thick densified metal layer of 1～5mm, the top of femoral stem is to be connected with the artificial femur neck and the position of implant infrastructure, there is oval artificial femur neck mounting structure the inboard, the work connecting device that the promising artificial femur handle in the outside, top is installed and pulled out.
