Abstract

The invention discloses a 3D-printed polyetheretherketone bone tissue symbiosis multihole skeleton substitute and a method thereof. The 3D-printed polyetheretherketone bone tissue symbiosis multiholeskeleton substitute comprises a bone tissue symbiosis region, wherein the bone tissue symbiosis region is a three-dimensional region where the bone substitute is in contact with bone tissue around thebone substitute and comprises a multihole region and an entity region, and the region except the bone tissue symbiosis region, in the substitute, is a bearing strengthening region. The problem that aPEEK material as a bone implant is difficult to be in symbiosis and combination with the bone tissue is solved, and the postoperative recovery of the PEEK bone implant is promoted.

Description

technical field [0001] The invention belongs to the field of medical technology, and in particular relates to a 3D printed polyether ether ketone bone tissue symbiotic porous bone substitute and a method thereof. Background technique [0002] For most bone defects caused by tumor resection, congenital malformations, and external trauma, only individualized design and manufacture can be carried out according to the defect characteristics of the patient. The characteristic of personalized implants is "tailor-made" for individual patients. , is also the mainstream development direction of clinical medicine in the future, and has huge market potential. Because the complex structure of personalized implants needs to be manufactured quickly and accurately, traditional manufacturing processes are difficult to meet the demand. As a kind of additive manufacturing technology, 3D printing technology has become one of the advanced biomanufacturing technologies widely recognized at home...
