Abstract
A composite of polymer or ceramic material has reinforcing fibers. The composite is for use in manufacturing medical implants like osteosynthesis plates, endoprostheses, screw coupling elements, surgical instruments, and similar components. The fibers and fibrous parts are made from a material that absorbs X-rays so that it can be seen during X-ray examination.
Claims16
A surgically implantable biocompatible component comprising:
- a composite of polymer or ceramic material;
- X-ray absorbing reinforcing fibers distributed throughout the composite, wherein an orientation of the X-ray absorbing reinforcing fibers is tailored to a shape and application of the surgically implantable biocompatible component (1, 18) in a defined manner to provide X-ray visibility control for the surgically implantable biocompatible component;
- and
- carbon fibers, wherein a total fiber percentage in the composite remains constant over a length or width of the biocompatible component, which changes a ratio of carbon fibers (6) to X-ray absorbing fibers (6).
1 more element
A surgically implantable biocompatible component in the form of a strip or plate assembly part comprising:
- a composite of polymer or ceramic material;
- X-ray absorbing reinforcing fibers distributed throughout the composite, wherein an orientation of the X-ray absorbing reinforcing fibers is tailored to a shape and application of the surgically implantable biocompatible component (1, 18) in a defined manner to provide X-ray visibility control for the component;
- wherein a concentration of fibers (6) is present in an area (A) of one or more recesses (14) or holes in the biocompatible component (18), and wherein the percentage of the X-ray absorbing fibers is reduced in the area (A).
