Bone defect filling scaffold structure

Abstract

The invention discloses a bone defect filling scaffold structure, which comprises a plurality of cylindrical base layers; meshed structures are arranged on the cylindrical base layers, and the plurality of cylindrical base layers are arranged in a mode of being nested layer by layer, wherein the axial length of the plurality of cylindrical base layers on the inner layer is greater than the axial length of the plurality of cylindrical base layers on the outer layer, so that two ends of the plurality of cylindrical base layers on the inner layer are protruded outwards along an axial direction ofthe cylindrical base layers to form two fixing parts; and the two fixing parts are inserted into medullary spaces of two fracture ends of a bone defect position when the bone defect filling scaffoldstructure is implanted into the bone defect position, so that the bone defect filling scaffold structure is fixed. Therefore, the bone defect filling scaffold structure of the embodiment, after beingimplanted into the defect position in a bone defect repair operation, can be effectively prevented from sliding; and a problem of the prior art that a bone defect repair scaffold, after being implanted onto the surface of a bone defect fracture end, slides is solved.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a bone defect filling bracket structure. Background technique [0002] The treatment of bone defects caused by various traumas, infections, and orthopedic diseases is still one of the medical problems. The existing bone defect treatment is generally by implanting a repair scaffold at the bone defect, and guiding the growth and repair of bone tissue through the repair scaffold. [0003] However, the traditional bone defect repair scaffolds are generally combined with the surface of the broken end of the bone defect on both sides, causing the repair scaffold to slip easily, resulting in rupture of new blood vessels and tissues, leading to severe inflammation and even secondary osteonecrosis. [0004] In addition, in the field of basic research in orthopedics, a large number of in vivo experiments have confirmed that after a bone defect occurs, the cortical bone on both sides of the...
