Abstract: 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 ?m 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.

Abstract: An artificial knee joint in which plural flexions are formed at a femur joint member includes a femur joint member which is joined to an end portion of a tibia near a femur; a tibia joint member which is joined to an end portion of a femur near a tibia; and a bearing member between the femur joint member and the tibia joint member, wherein the femur joint member includes plural side flexions which have various radii of curvature in order to make the contact surface become enlarged so that the stress may be dispersed at the contact portion with the tibia.

Abstract: An artificial knee joint is provided in which a flexion is formed at the bearing member and includes a femur joint member which is joined to an end portion of a tibia near a femur; a tibia joint member which is joined to an end portion of a femur near a tibia; and a bearing member between the femur joint member and the tibia joint member, wherein the bearing member includes a groove where a planar front flexion and a planar rear flexion at an upper plane, in order to provide an artificial knee joint movement similar to a real knee movement.

Abstract: An implant for correcting pectus excavatum is disclosed, which comprises a chest correction bar (30) inserted into a body for lifting a depressed sternum and costal cartilages, and a stabilizer (40) for being inserted into a distal end of the chest correction bar (30) to prevent the chest correction bar from being rotated inside the body, wherein the chest correction bar (30) is formed at both jagged distal ends thereof with recesses (33) each of a predetermined length along the lengthwise direction of the chest correction bar (30), and wherein the stabilizer (40) comprises: two fixing plates (41, 41?) for being fixed to the body of a patient; a bridge (42) connecting the two fixing plates (41, 41?); two protruders (43, 43?) each generally opposed from the fixing plates (41, 41?) so as to be hitched by the recesses (33) at the distal ends of the chest correction bar (30) inserted from under the bridge (42), where there are formed two spaces (C) each of a predetermined size between the two protuders (43, 43?)

Abstract: A prosthetic cage for spine adapted to be implanted in an intervertebral disc space between two vertebral bodies in a spine and to accommodate fusion of the disc space, said cage being a tubular body with an internal aperture, an external surface of which having a plurality of wall apertures each perpendicular to the longitudinal axis thereof and communicating with the internal aperture, and dual convex screw threads extended therefrom, such that the cage of the present invention has an advantage that the stability of fixation between the cage and the vertebral body can be achieved by simple variation of its shape.

Abstract: A frame fixator and operation system thereof, the fixator comprising an upper end ring and a lower end ring, and a plurality of length adjustment means coupled at both ends thereof to the upper end ring and the lower end ring, wherein the length adjustment means include an actuator, a moving member movable by the actuator and a digital indicator for indicating a length of the length adjustment means changeable to the movement of the moving member, the fixator and peration system for enabling to automatically adjust a distraction rate and distraction frequency of fracture during bone deformity correction and lengthening and to easily adjust the length by digitally indicating changed value of length according to manual or automatic manipulation.
