Abstract: An osteo-implant is provided, having a fixing segment and an implant end. The fixing segment is provided with a thread and at least one bone healing chamber. The bone healing chamber is located at a thread root of the thread. The bone healing chamber is a chamber inwardly depressed from a surface of the fixing segment. The fixing segment has a central axis. In the same section of the fixing segment, an area of a section, which is parallel to and passes through the central axis, of the at least one bone healing chamber closer to the implant end is smaller.

Abstract: A bionic fixing apparatus is provided. The bionic fixing apparatus includes a body having a through hole and at least one slit. The through hole penetrates the body from the top surface to the bottom surface to form a top opening and a bottom opening. An inner diameter of the top opening is larger than an inner diameter of the bottom opening. The slit is connected to the bottom opening and extends upwardly from the bottom surface of the body, such that the body has a flexible bottom portion.
