Abstract
The present invention relates to skull repairing material which is composite material of organic glass enhanced and modified by hybrid fiber composed of carbon fiber, or a blend composition of the carbon fiber, synthetic fiber or carbon felt or short carbon fiber and PMMA. The present invention is characterized in that the content of fiber components can be randomly selected from 6 to 60%, and a publicly known forming method of carbon fiber reinforced plastic is used for forming and processing a board or a matrix band of which the thickness is 1.5 to 4 millimeters. The present invention has the advantages of superior physical and chemical performance, fine biocompatibility, no rejection reaction, no carcinogenesis, easily obtained raw material, simple processing, easy large-scale production and easy popularization and application.
Description
The invention belongs to implantation or repair the material that human organ is used, exactly is a kind of materials for use in skull-fixing.
Because traffic and other reasonses such as industrial accident and cerebroma disease, China need implement skull repairing urethroptasty patient rises year by year, has exceeded in recent years more than year 100000 examples.The allosome material that skull repairing is used has metal, as titanium, lithium, rustless steel, chrome molybdenum nickel alloy etc.; Have nonmetal, as polyethylene from high pressure process, acrylate, silicone rubber, pottery and fiberglass etc., above material for various reasons, not extensive use as yet, present clinical usefulness mainly be lucite (polymethyl methacrylate).Lucite has many advantages, but property is crisp, and biological aging is poor, and temperature Change patient has sense of discomfort, produces hypohydrops etc., so all seek new material in research both at home and abroad." defect of skull and clinical " book (Hubei science and technology publishing house publishes in February, 1987) has been put down in writing a kind of spread by the mechanics designing requirement with carbon fiber and glass fiber cloth change (being that warp and parallel intersect by required different angles), flood medical high polymer (polymethyl methacrylate) then, promptly get the sheet material of 1 or 1.2 millimeters thick after bonding with bonding agent, in this sheet material, the orientation of fiber is oriented, its shock strength and ageing time all improve a lot, but processed complex, and glass fibre will the cracks behind material aging be separated out for a long time and is remained in the tissue.External also once reported the zoopery (" department of eye magazine ", the 524th～529 page of Anrc Otolaryngol 1976 the 9th phase) of repairing the dog sinus frontalis with carbon fiber-ptfe composite.This patent of French Patent (FRP) FR8511322(has also been applied for Europe and United States Patent (USP) EP86401626, US889326) disclose a kind of between two-layer carbon fiber shop one deck aromatic polyamide fibre that changes, resin with high elongation rate floods then, be processed into thickness less than 1 millimeter matrix band, this material poor plasticity, processed complex, inconvenience is promoted.
The purpose of this invention is to provide a kind of medical requirement that both satisfied, easy to process again, a kind of new materials for use in skull-fixing that is easy to popularize is to satisfy growing clinical needs.
Design of the present invention is that the shortcoming at lucite is strengthened and modification.Specifically use the chopped carbon fiber (B) of 3～20 millimeters long to strengthen and modification.Carbon fiber costs an arm and a leg, and for reducing cost, one or both the same carbon fibers (B) in also available synthetic fibers (C) or the carbon felt (D) mix composition assorted fibre (E) to be strengthened and modification.Above-mentioned fiber C and D also should be cut into 3～20 millimeters length, and same then carbon fiber (B) is mixed into the short assorted fibre (E) of cutting.Described carbon fiber (B) can be polyacrylonitrile-radical (PNA yl) or asphalt base carbon fiber; Synthetic fibers (C) can be any one or the two or more synthetic fibers that mix with the arbitrary proportion group such as terylene, polypropylene, nylon or aramid fiber.Resin (A) can be methyl methacrylate through polymerisation in bulk or suspension polymerisation or polymerisation in solution or emulsion polymerisation and polymethyl methacrylate (lucite, code name PMMA).It is characterized in that chopped strand composition (carbon fiber (B) or assorted fibre (the E)) consumption that enhancing modified is used is 6～60%, (percentage by weight, down together), surplus 40～94% is resin (A), when using weak point to cut assorted fibre (E), wherein carbon fiber (B) is no less than 6%, and synthetic fibers (C) and carbon felt (D) ratio are any; Reasonable composition is that the chopped strand composition consumption that enhancing modified is used is 10～45%, and surplus 55～90% is resin (A), and when using weak point to cut assorted fibre (E), wherein carbon fiber (B) is no less than 6%, and synthetic fibers (C) and carbon felt (D) ratio are any.
Forming method is to use the forming method of known carbon fibre reinforced plastic, as using sheet material or the matrix band that draws the method for dialling or injection moulding or die pressing etc. to be processed into 1.5～4 millimeters thick.Specifically will be cut into the chopped strand of 3～20 millimeters long exactly, same resin (A) is processed into injection molding material or molding compound by blending technology, then as required through injection moulding or compression molding, its interior short fiber random orientation of the material that obtains like this, uniform distribution, isotropic characteristics are arranged, and easy to process, be easy to apply.
Physicochemical property of this material and character all are better than lucite, see table 1 for details.
