However, according to the prior art, first, since the property of hydrophilicity decreases after a certain period of time, the implant must be taken out of the packaging material and subjected to hydrophilic treatment again. There is a problem that there is a great possibility of contamination due to exposure, and second, the distance between the UV lamp and the implant is not sufficiently close, and thus there is a problem that surface modification is not sufficiently performed or it takes a long time, and third, the implant is rotated for uniform surface treatment. In case of ordering or rotating the UV lamp, there is a problem that components, such as drive motors and gears, become more complicated and bulky. Fourth, the installation and removal of the implant into the UV irradiator is not easy and uncomfortable because it is not portable. there is a problem.

The above description of the background art is for helping understanding of the background of the invention, and may include matters other than the prior art already known to those skilled in the art to which this technology belongs.
