By protruding the plurality of micro-projections 10 to such a implant can be limited to the contact surface between the implant and the human tissue as a micro-projection longitudinal section, it can minimize the absorption of bone, etc. that can occur through this. In addition, the protruding micro-projections may act as a barrier to prevent the implant from slipping in the tissue, thereby alleviating the phenomenon that the implant is not fixed to the surgical site due to a decrease in affinity with the tissue and the like.
또한, 복수의 미세돌기의 종단면을 오목한 현상으로 함으로써 마치 문어발과 같은 효과를 얻을 수 있다. 즉 복수의 미세돌기의 종단면이 수술부위에 접촉하여 탄성에 의하여 복원될 때 접촉면 내부에 진공이 형성되게 함으로써 빨판처럼 보형물의 인체 조직에 대한 흡착력을 증대시킬 수 있다.Further, by making the longitudinal cross sections of the plurality of fine protrusions concave, it is possible to obtain an effect similar to that of an octopus foot. That is, when the end surfaces of the plurality of microprojections contact the surgical site and are restored by elasticity, a vacuum is formed inside the contact surface, thereby increasing the adsorption force of the prosthesis on the human tissue like a sucker.

The plurality of fine protrusions 10 according to the embodiment of the present invention are made of a material having excellent biocompatibility and a good cushioning or elasticity. For example, it can be made of silicon.
여기서 복수의 미세돌기의 길이는 수술부위에 따라 상기 종단면이 수술부위에 접촉될 수 있도록 다양하다. 즉 오목하게 들어간 수술부위에서는 미세돌기의 길이를 길게 하고, 볼록하게 나온 수술부위에서는 미세돌기의 길이를 짧게 한다. 이를 통해 수술부위에 굴곡이 있는 경우에도 미세돌기의 종단면이 조직에 접촉되어 고정된다. Here, the length of the plurality of microprojections may vary so that the longitudinal section is in contact with the surgical site according to the surgical site. That is, the concave surgical site lengthens the microprojections, and the convex surgical site shortens the length of the microprojections. Through this, even if there is a bend in the surgical site, the longitudinal section of the microprojections is fixed in contact with the tissue.
