摘要:
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′) and two lateral lengthwise surfaces of the bridge (42) so that the distal ends of the chest correction bar (30) can be inserted thereinto, thereby allowing the stabilizer (40) to be easily inserted into the chest correction bar (30), and once the insertion is made, pain and infection caused by stimulation on incised portions of a patient can be prevented.

Disclosed is a method for minimizing interference between RFID readers built in a mobile terminal, it is possible to minimize interference between readers by assigning an operating time specific to the mobile terminal at a specific point of time of a cycle of a mobile communication network signal according to an identity number of a mobile terminal, even when several readers are scattered in a predetermined area and they try to detect one tag at the same time.
摘要:
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.
