Living tissue active surface, implant, method of forming living tissue active surface, manufacturing method of implant

摘要

The living tissue sliding surface 30 in close contact with the living tissues H and S is made of a biocompatible material, and has a large number of the villi 41 of the fingertip shape. The villi (41) have a tip diameter of nanometers. The implant 1 has a living tissue sticking surface 30 on the surfaces 11 and 24 that adhere to the living tissues H and S. As shown in FIG. In the method for forming the living tissue sliding surface 30, laser non-thermal processing for irradiating laser light in the air is performed on the surface of the biocompatible material to form a large number of uncut hairs 41 having a fingertip shape. The laser light is the laser light of the extreme pulse laser.
