Abstract
The invention provides a bone trabecula bionic part and an implant, and belongs to the technical field of medical instruments. The bone trabecula bionic piece comprises a bone trabecula bionic body and a net-shaped protective shell, the net-shaped protective shell is of a cylindrical structure, a hollow hole is formed in a cylinder of the net-shaped protective shell, and a first external thread is arranged on the outer cylinder wall of the net-shaped protective shell; and a containing cavity is formed in the net-shaped protective shell in a hollow mode, and the bone trabecula bionic body is contained in the containing cavity. The implant comprises a connecting piece and the bone trabecula bionic piece, the connecting piece comprises a first connecting body and a second connecting body in the length direction of the connecting piece, and the second connecting body extends into the hollow hole of the bone trabecula bionic piece and is connected with the bone trabecula bionic piece. The net-shaped protective shell of the bone trabecula bionic piece can play a role in wrapping and supporting the bone trabecula bionic body, so that the influence on implantation and complications caused by fracture of the bone trabecula bionic piece in the implantation process are reduced; and in addition, the net-shaped protective shell can be connected with bone tissue, and the effective bone bonding length of the bone trabecula bionic piece can be effectively increased.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to a trabecular bone bionic part and an implant. Background technique [0002] Oral craniofacial implant technology is to implant the implant with good biocompatibility with the human body into the jawbone of the human oral cavity or the bone tissue of the craniofacial defect through surgery, as an artificial tooth root or craniofacial prosthesis. Body retainer, a technique for repairing oral, maxillary and craniofacial defects. The current advanced osseous fusion implant system is not only used for implant denture repair, but also as a fixation device for repairing defects, it can also be implanted in the zygomatic bone, skull, mastoid process, and periorbital to complete maxillofacial prosthetics, artificial ears, artificial eyes, etc. The retention of prosthetics and hearing aids solves some problems in the repair of oral craniomaxillofacial defects caused by trauma and ...
