Problems solved by technology

[0002] In various orthopedic resections, artificial joint replacements, orthodontic surgeries, bone defects of different degrees are encountered. In the past, the conventional solution was to use autologous or allogeneic bone blocks, bone granules, and bone paste to remove the defects. However, due to the limited source of autologous bone, the price of allogeneic bone is expensive and there are biological risks, so not everyone needs bone defect Filled patients can get satisfactory treatment

Embodiment Construction

[0025] The specific implementation of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0026] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 , Figure 7 , as shown, the bone graft filling metal granules (1) of the present invention are in the shape of spheres, cylinders, polyhedrons, spirals, mesh bodies, and combinations of the aforementioned various shapes. The outer dimensions of the granules are 2-2 15mm, the bone graft hole (2) is provided on the bone graft filling metal particle body (1) to accommodate the implantation of crushed bone particles or bone paste, and the bone graft hole (2) is formed by the bone graft filling metal particle body (1) Extending inward, the bone graft holes (2) have a diameter of 1 to 10 mm, and the bone graft holes (2) are connected to each other, such as Figure 8 The outer surface of the metal solid body (1) and the inner surface of the bone gr...

Abstract

The invention relates to a bone grafting filler metal particle body which is used for bone defect filling. Bone grafting holes for containing grafted broken bone particles or bone paste are formed on the bone grafting filler metal particle body and are in interpenetrated connection with one another, and micropores which are communicated with one another are formed on the external surface of the particle body and the internal surfaces of the bone grafting holes. When surgery is performed, a certain amount of bone grafting filler metal particle bodies is mixed with autogenous bones or bone blocks, bone particles and bone paste of allogenic bones according to the requirement for bone defect filling, the fillers of autogenous bones or the allogenic bones can be partially replaced in an occupation manner, bone cells and microvessels grow into the insides of the bone grafting filler metal particle bodies during the recovery process of a patient, and a fusion embedded bone repairing body with biological activity can be formed.

Description

technical field [0001] The invention relates to an orthopedic surgical implant, in particular to a bone graft filling metal granule used for bone defect filling. Background technique [0002] In various orthopedic resections, artificial joint replacements, orthodontic surgeries, various degrees of bone defects are encountered. In the past, the conventional solution was to use autologous or allogeneic bone blocks, bone granules, and bone paste to remove the defects. However, due to the limited source of autologous bone, the price of allogeneic bone is expensive and there are biological risks, so not everyone needs bone defect Filled patients can get satisfactory treatment. Contents of the invention [0003] The purpose of the present invention is to provide a bone graft filling metal granule body. During the operation, a certain amount of bone graft filling metal granule body can be mixed and stirred with autologous bone or allogeneic bone bone block, bone granule and bone...
