Embodiment 1

[0039] Embodiment 1 A kind of preparation method of the humerus model of 3D printing

[0040] The images and data of the humerus and fracture on both sides of the patient were obtained through 64-slice spiral CT scanning; the data were imported into the computer for analysis, and the humerus on both sides was analyzed. Through adjustment and analysis, the humerus on the non-fracture side and the humerus on the fracture side were mirror-symmetrical. Mirror the humerus on the non-fracture side, so as to obtain a complete three-dimensional mirror image humerus 6 consistent with the fracture side humerus; analyze the fracture surface 14 and the size of the bone fragment 5 at the fracture, and generate a three-dimensional fracture surface 14 and bone fragment 5; The three-dimensional image of the mirror image of the humerus 6 and the three-dimensional images of the fractured bone and its fracture surface 14 and the bone fragment 5 are placed side by side, and the fracture surface 14...

Embodiment 2

[0043] Embodiment 2 A kind of humerus model of 3D printing

[0044]A 3D printed humerus model, which includes a humerus shaft 1, a humerus proximal end 2, a humerus distal end 3, a fracture surface 14 and / or 10 bone fragments 5; wherein the humerus model also includes a 3D printed fractured humerus pair The mirror humerus 6 structure of the lateral humerus, when the fracture surface 14 is at the humeral head 4 and replacement of the humeral head 4 is required, a cross section 7 is set under the fracture surface 14, and the humeral head rod entry hole 8 is set under the cross section 7; the mirror image of the humerus 6 structure corresponds to a cross-section 7, which divides the mirrored humerus 6 into two parts, one part is the upper humeral head 4 structure, the lower part is the humeral shaft 1 structure, and the humeral head rod 9 is set at the cross-section 7 of the humeral head 4 structure . The setting of the cross section 7, the humeral head rod entry hole 8 and the ...

[0045] Embodiment 3 A kind of humerus model of 3D printing

[0046] A 3D printed humerus model, which includes a humerus shaft 1, a humerus proximal end 2, a humerus distal end 3, a fracture surface 14 and / or 10 bone fragments 5; wherein the humerus model also includes a 3D printed fractured humerus pair The mirror humerus 6 structure of the lateral humerus, when the fracture surface 14 is at the humeral head 4 and replacement of the humeral head 4 is required, a cross section 7 is set under the fracture surface 14, and the humeral head rod entry hole 8 is set under the cross section 7; the mirror image of the humerus 6 structure corresponds to a cross-section 7, which divides the mirrored humerus 6 into two parts, one part is the upper humeral head 4 structure, the lower part is the humeral shaft 1 structure, and the humeral head rod 9 is set at the cross-section 7 of the humeral head 4 structure .

Abstract

The invention provides a 3D printed humerus model which comprises a humerus shaft, a humerus near end, a humerus rear end, a fracture face and / or 10 or less broken bones. The humerus model further comprises mirror image humerus structures of a 3D printed fractured humerus to the side humeri, wherein a nail inlet hole or a structure needed in the other operation processes is arranged nearby the fracture face. A model manufacturing method comprises the steps that images and three-dimensional data of the two side humeri or the fractured part are obtained in a 64-row spiral CT scanning mode, data of the mirror image humerus structures of the fractured humerus model and the opposite side humeri by analyzing the three-dimensional data, and then the mode is switched into a 3D printing identification mode for model printing. By comparing the mirror image humerus structures and the fractured humerus structure, an operator can be visually and efficiently helped to operate, and a young doctor can visually know operating steps and easily communicate with a patient with a solid structure. The 3D printed humerus model is reasonable in structure and convenient to use.

Description

technical field [0001] The invention belongs to orthopedics, in particular to a simulation structure used for humerus fracture, and specifically relates to a 3D printed humerus model and a preparation method thereof. Background technique [0002] Fractures of the proximal humerus account for 4%-5% of all fractures in the body, and the incidence rate is very high in the elderly. Due to the anatomical characteristics of the bones and muscles of the proximal humerus and factors such as osteoporosis in the elderly, clinical treatment is relatively difficult, and improper treatment is often This leads to the occurrence of shoulder joint stiffness, nonunion and malunion. Open reduction and internal fixation will cause greater damage to soft tissue, further damage the blood supply of the humeral head, increase the risk of avascular necrosis and bone nonunion of the humeral head, and the treatment effect of severe comminuted fractures and elderly patients with osteoporosis is not go...
