SKULL REPAIR SYSTEM AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/103640
Kind Code:
A1
Abstract:
A skull repair system and a preparation method therefor. The skull repair system comprises a repair main body (1) formed with a polyaryletherketone-based material. Tabs (3) are provided on the repair main body (1) and comprise extended parts (21) for connecting the repair main body (1) and an autogenous skull (4). The tabs (3) and the repair main body (1) are integrally formed. The shape, size and radian of the skull repair system match those of a defective skull. The tabs (3) facilitate fixation of the skull repair system during surgery, eliminating the need for an additional connecting part for connecting the repair main body (1) with the autologous skull (4), and can prevent collapse after repair. The skull repair system is formed with a polyaryletherketone-based material, and thus has good biocompatibility, avoiding rejection. The preparation process is simple and efficient. The skull repair system obtained after a three-dimensional design and an optimized treatment accurately matches the defected site, making it easier to use. The special design of the tab connecting part (22) facilitates formation of a smooth repaired surface after a surgery, making the repairing surface being visually pleasing.
