Implant device for promoting bone growth

Abstract

In order to promote bone growth without damage of a growth plate to improve the stability of a procedure, the present invention provides an implant device for promoting bone growth, the device comprising: a first implant bar implanted to penetrate a metaphysis corresponding to the inside of a growth plate of a long bone to be treated; a second implant bar implanted to penetrate an epiphysis of the outside of the growth plate; and a stimulation elongation means disposed close to the external surface of the long bone to be treated and installed under skin tissues surrounding the long bone to be treated, and being elongated between end portions of the implant bars to increase a gap between the implant bars to cause the growth plate to be extended.

Description

TECHNICAL FIELD[0001]The present disclosure relates to an implant device for promoting bone growth, and more particularly, to an implant device for promoting bone growth, which is configured to promote bone growth without damage of a growth plate, thereby improving the safety of a procedure.BACKGROUND ART[0002]In general, a long bone, such as a femur, a tibia, a humerus, and the like, includes a diaphysis forming a central portion of the long bone, a metaphysis provided at both end portions of the diaphysis, and an epiphysis provided outside the metaphysis. Also, a growth plate is located between the metaphysis and the epiphysis. In this case, a medullary cavity, which is filled with bone marrow, is present inside the diaphysis, and a bone may be grown by the growth plate.[0003]Here, it is known that a length growth of the growth plate of the long bone is inhibited when the growth plate of the long bone receives compressive force inward from the epiphysis toward the metaphysis, whil...

AI Technical Summary

Benefits of technology

The present invention provides an implant device for promoting bone growth that has the following technical effects: 1. The implant device is compact and can be easily worn, improving convenience for users. 2. The device can promote bone growth uniformly by elongating both exposed ends of the implant bars that are implanted to penetrate the growth plate of a long bone. 3. The device can correct rotational deformation of the growth plate by inducing more active growth promotion effect on the growth plate corresponding to the direction in which the long bone is curved. 4. The device can minimize sensation of foreign materials and prevent damage to the growth plate by giving stable stimulation and dispersing pressure slantwise during shape deformation.

Problems solved by technology

Since skin tissues are subject to pressure together during the stimulation of the growth plate, excessive force applied to the skin tissues, thereby causing a wearer to suffer pain.

In addition, there has been a problem that the wearer cannot live everyday life due to a device exposed outside.

Furthermore, since it is hard to apply uniform tensile stress to each portion of the growth plate, there have been serious problems of causing non-uniform bone growth or damaging the growth plate by applying excessive force to the growth plate.
