Skull repairing patch and preparation method thereof

Abstract

The invention discloses a skull repairing patch and a preparation method thereof. The skull repairing patch is formed by laminating one layer of carbon fiber knitted fabric and one or two layers of carbon fiber cloth, wherein the carbon fiber cloth is formed by overlapping carbon fiber woven cloth and carbon fiber non-woven cloth; matrix carbon and / or silicon carbide are / is filled between the carbon fibers of the carbon fiber knitted fabric and the carbon fiber cloth. The skull repair patch has the characteristics of light weight, good biocompatibility, good chemical stability, mechanical properties similar to those of human bones, good fatigue, strong designability, no artifacts and the like, and is particularly suitable for skull repair.

Description

technical field [0001] The invention relates to a skull patch, in particular to a carbon fiber composite skull patch and a preparation method thereof, belonging to the technical field of biomedical materials. Background technique [0002] Craniocerebral defects with a diameter greater than 3 cm due to trauma, infection, tumor, surgery, etc. may produce clinical symptoms. In order to keep the cranial cavity closed, restore the patient's shape, and avoid physiological abnormalities, skull repair surgery is required. [0003] The materials used for cranioplasty mainly include autologous bone, artificial polymers, metals and other materials are commonly used materials for cranioplasty. In comparison, titanium alloys are ideal in terms of rigidity, strength, plasticity, and biocompatibility, but they have certain defects: (1) Poor mechanical compatibility, uneven stress distribution, loosening of implants or Dislocation, local osteoporosis, bone resorption, fracture, delayed bo...

AI Technical Summary

Problems solved by technology

In comparison, titanium alloys are ideal in terms of rigidity, strength, plasticity, and biocompatibility, but they have certain defects: (1) Poor mechanical compatibility, uneven stress distribution, loosening of implants or Dislocation, local osteoporosis, bone resorption, fracture, delayed bone healing, etc.

(2) The edge is usually sharp and easy to damage the skin, resulting in the exposure of the implant; (3) The thermal conductivity is high, which can cause discomfort to the patient under large temperature differences

(5) There are artifacts in the medical examination, which will affect the later diagnosis and rehabilitation treatment

Carbon materials have good biocompatibility and have been applied in many aspects of biomedicine. However, there are no related reports on the successful design and preparation of skull repair pieces using carbon materials in the prior art.
