A rod system pore structure and its orthopedic implant

Abstract

The invention discloses a rod-system pore structure for an orthopedic implant. The rod-system pore structure comprises a plurality of structural units, wherein each structural unit is formed by four rod pieces according to specific spatial positions; the structural units are combined into a three-dimensional space aperture structure system in a transformation or duplication way; the four rod pieces of each structural unit comprise a first rod piece, a second rod piece, a third rod piece and a Z rod piece; the rod-system aperture structure forms a specific shape according to actual clinical needs to form the orthopedic implant. The rod-system pore structure has structural characteristics similar to those of the bone trabecula of a human body, and is high in porosity, and an ideal spatial structure can be provided for the growth of new bones; in terms of mechanical performance, the rod-system pore structure is low in structural rigidity and strong in mechanical strength, stress shielding can be well reduced, and effective mechanical support can be maintained; the orthopedic implant formed by the rod-system pore structure has high mechanical performance and bone conduction and bone induction properties, and is widely applied to the clinical use of maintenance, support, repair and the like of human bones.

Description

technical field [0001] The invention relates to a medical surgical implant, in particular to a rod system pore structure and an orthopedic implant, belonging to the technical field of biomedical engineering. Background technique [0002] Bone defect caused by disease and trauma is a common clinical disease and one of the worldwide problems in orthopedic treatment, seriously affecting the quality of life of patients. Orthopedic implants are a general term for a large class of implants that replace, repair, supplement, and fill human bones. They are used to maintain, support, and repair human bones. They are currently clinically used orthopedic medical materials. The wide application of orthopedic implants in orthopedic treatment has significantly improved the problems that could not be solved clinically in the past, and the success rate of implantation has also reached quite satisfactory results. However, the existing orthopedic implants generally have disadvantages such as ...
