Embodiment Construction
[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. The following description of at least one exemplary embodiment is merely illustrative in nature and in no way taken as limiting the invention, its application or uses. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0027] Such as Figure 1 to Figure 5 As shown, the embodiment of the present invention provides a pelvic prosthesis, comprising: an ilium component 10, the ilium component 10 is used to connect with the residual ilium; an acetabular component, the acetabular component includes a supporting par...

The invention provides a pelvis prosthesis. An ilium component and an acetabular component are arranged in a pelvis prosthesis; the acetabular component comprises a supporting part, an elastic part, adjusting structures and fixing parts, wherein the supporting part is detachably connected with the ilium component; the elastic part is arranged on the supporting part; the fixing parts are connectedwith residue acetabular; and each adjusting structure can adjust the distance between the corresponding fixing part and the supporting part. Through the adoption of the technical scheme of the pelvisprosthesis disclosed by the invention, a complete acetabular can be formed through the acetabular component and surplus acetabular skeleton of a patient after resecting, and epiphysis is reserved, sothat after operation, the acetabular and the thighbone can grow; along with the growth of the age of the patient, the distance between each fixing part and the supporting part can be adjusted, and thesize of fossa acetabuli of the prosthesis can be enlarged to a certain degree, so that the situation that the growth of the residue acetabular is limited by the prosthesis is avoided; besides, the elastic part can replace the function of the resected acetabular cartilage, so that original anatomical structure and the elasticity of the acetabular are guaranteed, and along with the situation that the femoral head of the patient is enlarged, the elasticity of the elastic part can enable the size of the fossa acetabula to be increased to a certain degree.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to a pelvic prosthesis. Background technique [0002] Surgical treatment is the main treatment method for pelvic malignant tumors. Its resection and reconstruction technology represents the top level in the field of bone tumor surgical treatment, especially for malignant tumors that invade the acetabular area. Effective reconstruction is still an unresolved problem. [0003] On the other hand, the proportion of patients with malignant bone tumors in children and adolescents is relatively high, and since the epiphysis is not closed in children and adolescents, and bone tumors generally do not invade the epiphysis, the goal of limb salvage treatment for malignant bone tumors in children and adolescents is not only to preserve limbs, More attention should be paid to how to preserve the epiphysis to ensure the growth of limbs after limb salvage and improve the function of limbs...
