20150025645 | ARTIFICIAL KNEE JOINT - This invention relates to an artificial knee joint component capable of adjusting alignment or balancing (extension gap and flexion gap) between the tibia and the femur. | 01-22-2015 |
20130310946 | ACETABULAR CUP FOR AN ARTIFICIAL HIP JOINT AND BEARING, AND ACETABULAR CUP ASSEMBLY - An acetabular cup assembly for an artificial hip joint includes an acetabular cup including a seating recess, a female taper formed on an inner wall, protrusion recesses formed to communicate with the seating recess and insertion recesses each positioned inside a corresponding one of the protrusion recesses; and a bearing including a male taper on an outer circumference thereof, protrusions inserted into the protrusion recesses, and insertion protruding portions each formed on a corresponding one of the protrusions, the insertion protruding portions being inserted into the insertion recesses. A polyethylene bearing can be firmly fixed to the acetabular cup. When a ceramic bearing made is inserted into the acetabular cup, the area where the bearing adjoins the acetabular cup is increased, thereby preventing the ceramic bearing from being broken. Since no groove is formed along the entire circumference of the acetabular cup, the strength is increased. | 11-21-2013 |
20130282135 | IMPLANT FOR IN-VIVO INSERTION WHICH IS FORMED WITH A POROUS COATING LAYER THEREON - The present invention relates to an implant which is surgically inserted in vivo such as an artificial knee joint or artificial hip joint. More particularly, the present invention relates to an implant for in-vivo insertion, wherein the porosity of a porous coating layer formed on the surface of the implant, thus increasing the bone adhesion of the implant into pores, the adhesivity between the implant and the porous coating layer and the adhesivity between particles in the porous coating layer, wherein vertically-curved pores each having a radius of 100˜300 μm are formed in the porous coating layer to increase the adhesivity of the implant to the bone growing into the pores, thus increasing bone adhesion, and wherein the ratio of interconnected pores in the porous coating layer is increased, and thus bones growing into the pores are interconnected, thereby increasing the adhesivity between the implant and the bones. | 10-24-2013 |
