Method for individualized customization of sacrum reconstruction plate by 3D printing and sacrum reconstruction plate

Abstract

The invention relates to a method for individualized customization of a sacrum reconstruction plate by 3D printing and the sacrum reconstruction plate. The method comprises the following steps: obtaining range simulation data of a to-be reconstructed sacrum and reconstructing lateral pelvic simulation data; performing smooth treatment and repair on a sacrum dorsal profile and outputting a first draft of the sacrum reconstruction plate; performing simulation matching in simulation software by utilizing data of a half pelvic prosthesis and first draft data of the sacrum reconstruction plate; designing a bolt base on the sacrum reconstruction plate; designing a metal mesh bone joint surface of 1 mm on the sacrum reconstruction plate bone joint surface; designing a nail hole in the sacrum reconstruction plate; forming a sacrum reconstruction plate blank; performing surgical simulation matching on the sacrum reconstruction plate serving as a finished product and the half pelvic prosthesis. The method provided by the invention has the benefits that the fixing of the half pelvic prosthesis can be enabled to a maximum degree, and the problem of infirm fixing caused as the sacrum or the pelvic prosthesis is propped against a surrounding soft tissue or a nail stick system for a spinal column is solved.

Description

Technical field [0001] The invention relates to the technical field of medical devices, and in particular to a method for 3D printing an individualized customized sacral reconstruction plate and a sacral reconstruction plate. Background technique [0002] Orthopedics cases of sacral tumors are relatively rare, so there is a lack of corresponding sacral reconstruction prostheses on the market. Whether it is a primary tumor or a metastatic tumor, sacral tumors often need to be removed. There is a lack of suitable prosthesis for reconstruction after sacral tumor resection. Existing custom prostheses lack communication with doctors. The products designed are difficult to meet the requirements of doctors. The design cycle of custom prostheses is long and the manufacturing cost is high. The surface treatment of prostheses manufactured by conventional production methods The effect is poor, and the effect of bone ingrowth is poor. [0003] In view of the above-mentioned shortcomings, the...
