This invention relates to a prosthesis for implantation into bone defects. Specifically, it discloses a cranioplasty component, comprising: a bone flap body for filling a defect in the skull, the bone flap body including a disc-shaped filling body and multiple stimulation units arranged circumferentially between the outer and inner disc surfaces of the filling body, and each stimulation unit being capable of protruding from the sidewall of the filling body through radial movement; a force-applying component for driving each stimulation unit to protrude radially from the sidewall of the filling body, thereby, after the bone flap body fills the defect, the force-applying component drives each stimulation unit to protrude from the sidewall of the filling body, causing the radially outer ends of the stimulation units to press against the sidewall of the defect to stimulate the bone of the sidewall of the defect; and a positioning component for attaching and positioning the bone flap body to the skull.

Proposed is a non-fixing implant made of a raw material including a biomaterial and a ceramic-based composite material having excellent osteoconductivity in addition to a polymer. The non-fixing implant can be accurately secured to a gap between the skull and the bone flap and can be conveniently used. Further proposed is a method of manufacturing the non-fixing implant. The non-fixing implant includes a flexible wedge deformable to conform to the external contour of the bone flap and a plurality of wings connected to an upper or lower portion of the flexible wedge and extending to both sides of the flexible wedge. The wings have a porous structure. The wings on one side will be positioned on the bone flap and the wings on the other side will positioned on the skull. The non-fixing implant has the advantage of being capable of accurately filling a defect formed by craniotomy, has improved biocompatibility and bone bonding ability, and allows tissue invasion.

The application discloses an adjustable skull lock and relates to the technical field of medical devices. Technical points are as follows: the skull lock comprises an upper cover piece, a through hole is arranged on the upper cover piece, a stand is arranged in the through hole and connected with the through hole through a first locking assembly, one side of the upper end of the stand is provided with a mounting groove, the upper end of the mounting groove is fixed on the upper cover piece, a lower cover piece is arranged below the other opposite side of the stand, a plug is arranged in the mounting groove and connected with the mounting groove through a second locking assembly, and the lower end of the plug is fixedly connected with the upper cover piece. The upper cover piece and the lower cover piece in the skull lock can fix the skull of a patient, the upper cover piece and the upper cover piece tooth can fix the skull prosthesis, so that the skull lock can be applied to the fixation of various free bone flaps, artificial skull prosthesis implant bodies with different thicknesses and original skulls, and the problem of skull fixation failure caused by the thickness difference between the skull of a patient and a skull prosthesis in the prior art can be effectively solved.
