Description

TECHNICAL FIELD [0001] The present invention relates to an artificial bone structure and artificial bone structure,

The present invention relates to an artificial joint comprising an artificial bone structure and an artificial bone structure.

 It is called a joint in which the bones forming the skeleton are connected by two or more joint bones and cartilage.

All of the human body movements are performed at joints called movable joints, and the movable joints connect most of the human skeleton.

However, joints of patients whose cartilage or joint bones are destroyed or damaged due to arthritis or bone tumors do not function as joints

Therefore, artificial joints are being used to replace broken or damaged joints.

The artificial joint cuts the injured joint bone and is implanted into the severed joint to function as a joint.

At this time, since a part of the artificial joint is inserted and fixed to the bone joint formed at the removed joint bone, a long time must elapse for the artificial joint and the bone to be united without the artificial joint being separated from the bone.

However, if the artificial joint is not firmly fixed to the bone node, a part of the artificial joint may be detached from the bone node or the artificial joint and the bone node may be shifted.

In addition, since the length of the joint bone to be cut varies according to the state of the joint, artificial joints corresponding to the cutting state of each joint are required.

Therefore, if the existing artificial joints can not replace the severed joint bones, new artificial joints should be manufactured. Therefore, if the artificial joint preparation period is delayed, the joint treatment is delayed, the cost of producing artificial joints increases, A difficult management problem arises.

Korea registered patent No. 1168783 (registered on July 19, 2012)
