7 results about "Bone flaps" patented technology

The invention relates to a prosthesis used for being implanted into a defect area of a bone, and particularly discloses a skull repairing component which comprises a bone flap body used for being filled in the defect area of the skull, and the bone flap body comprises a disc-shaped filling body and a plurality of stimulation units. The plurality of stimulation units are circumferentially arranged between the outer disc surface and the inner disc surface of the filling main body, and each stimulation unit can protrude out of the side wall of the filling main body through radial movement; and the force application part is used for driving the stimulation units to radially protrude out of the side wall of the filling main body, so that after the bone flap body is filled in the defect area, the stimulation units are driven to stimulate the bone flap body. The force applying component drives the stimulation units to protrude out of the side wall of the filling body, so that the radial outer ends of the stimulation units are pressed against the side wall of the defect area to stimulate the bone body of the side wall of the defect area; and the positioning component is used for combining and positioning the bone flap body and the skull.

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.

The invention relates to an implant for closing a defective area of a skull, and specifically discloses a skull flap comprising a flap body and a compensation member attached to an edge of the flap body, the compensation component serves as a prosthesis component to form a composite bone flap with the bone flap body so as to be used for backfilling and closing a defect area of a skull, and a plurality of elastic contact pins which are distributed in the circumferential direction are arranged on the compensation component in advance. The composite bone flap is allowed to be backfilled in the defect area by enabling the elastic contact pins to elastically deform inwards, and after the composite bone flap is backfilled in the defect area, the gap is filled with the compensation component, and the elastic contact pins on the compensation component make elastic contact with the side wall of the edge of the skull to stimulate the bone body on 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.

The application discloses a skull bone flap fixing device, relates to the technical field of skull bone flap fixing, and aims to solve the problems that most of the existing skull bone flap fixing devices are fixed through the mode of extrusion from different directions, are prone to cause extrusion damage to the edge of the skull bone flap, and are prone to be rubbed and damaged when being taken. The upper end of the fixing base is provided with an air leakage prevention sealing cover; further comprising: an air outlet pipe arranged on the upper surface of the air leakage prevention sealing cover and welded and connected with the air leakage prevention sealing cover, the upper end of the air outlet pipe is provided with a diffusion horn pipe, the diffusion horn pipe and the air outlet pipe are an integral structure, through air cavities are arranged in the air outlet pipe and the diffusion horn pipe, and the through air cavities penetrate through the air leakage prevention sealing cover; a mounting cavity is arranged in the inside of the fixing base and is an integral structure with the fixing base, and a hair dryer is arranged in the inside of the mounting cavity.

The application discloses a skull repair fixing method, which comprises a drilling fixing part and a connecting part; the drilling fixing part comprises a drilling expansion fixing part; the drilling expansion fixing part is annular with an opening; the center position of the drilling expansion fixing part is a conical screw hole; two sides of the opening of the drilling expansion fixing part are respectively provided with bone flap fixing parts; after the drilling expansion fixing part is placed into a drilling hole on a skull, a screw is screwed into the conical screw hole, and the drilling expansion fixing part is clamped in the drilling hole after expansion; the two ends of the connecting part are respectively provided with a clamping groove for clamping a bone flap and a clamping groove for clamping a skull. The skull repair fixing method is simple in operation, does not need metal nail fixing, and has no additional protruding part on the skull, so that the mental state of a patient after operation is better.
