Skull repair material and preparation method for same

Abstract

The invention discloses an artificial skull repair material, and belongs to the technical field of orthopaedic repair materials. The artificial skull repair material comprises the following components in parts by weight: 15 to 29 parts of bone cement, 11 to 35 parts of a 3D (3-dimensional) titanium mesh, 11 to 17 parts of a polylactic acid composite material chitin and 15 to 21 parts of polyetheretherketone. The invention further provides a preparation method for the artificial skull repair material. A skull structure with a required radian can be rapidly prepared by adopting a 3D printing technology. The skull repair material comprising the components in parts by weight is processed to prepare skull prosthesis with any required radian by adopting the 3D printing technology, and is high in biocompatibility and low in cost, the advantages of materials such as the bone cement and the 3D titanium mesh are integrated, the shortcomings of a common skull repair material in terms of mechanical performance, processibility and consistency are effectively overcome, and meanwhile, side effects in clinical applications are obviously reduced.

Description

technical field [0001] The invention discloses an artificial skull repair material and a preparation method thereof, belonging to the technical field of orthopedic repair materials. Background technique [0002] Cranioplasty is a common operation in brain surgery to repair skull defects caused by traumatic brain injury and craniotomy. Skull repair surgery is mainly to solve problems such as lack of effective protection of brain tissue in the defect area, blood supply disorder, and abnormal circulation of cerebrospinal fluid. It also needs to solve the problem of shape repair and plastic surgery. [0003] At present, skull repair surgery usually uses autologous skull flap for skull repair, metal substitute repair, and three-dimensional CT. But what kind of repair material to use is the key issue of repair surgery. [0004] Titanium mesh is now commonly used in medicine to make skull repair prostheses. Although titanium mesh has the characteristics of good tissue compatibili...

Problems solved by technology

The above-mentioned self-bone has the following disadvantages: a second operation area needs to be opened, the bone source is limited, an additional operation is required, the graft can be absorbed, and it will cause different degrees of damage to the bone tissue, which increases the pain of the patient and the plastic effect is poor. The appearance is not good; the surgical trauma is large, the source of bone fragments is limited, especially the poor plasticity, which greatly limits its clinical practice

Its disadvantages are: biologically inert materials, after long-term implantation in the human body, the interface between it and bone tissue is clear, and the heat dissipation of bone cement will damage the brain tissue when it is set;
