Problems solved by technology

Chinese fir bark splints also have the disadvantages of reduced water absorption strength, unstable density, easy to mold and difficult to store, which is not conducive to the large-scale promotion and application of fir bark splints. There is no application of fir bark splints abroad. The promotion of new bionic materials of fir tree fiber can not only alleviate the oil crisis and solve the problem of environmental pollution, but also allow the bionic splint of traditional Chinese medicine to go to the world

Abstract

The invention discloses a cedar fiber bionic traditional Chinese medicine bonesetting splint and a manufacturing method thereof.The manufacturing method comprises the following steps that after cedar is smashed into cedar fibers, soda boiling, cleaning, sterilization and disinfection, secondary cleaning, drying and secondary smashing are conducted, and pretreated cedar fibers are obtained; blending the pretreated cedar fiber and a thermoplastic high polymer material, extruding and granulating, and extruding into a filamentous structure to obtain a filament segment; and after the wire sections are filled into a cold pressing mold in the same direction, the nano-particle dispersion liquid is sprayed into the cold pressing mold, the cold pressing mold is oscillated, the wire sections in the cold pressing mold are subjected to cold pressing, and the plate is obtained. After the plate is placed on a traditional Chinese medicine bonesetting splint mold with a needle-shaped structure, hot pressing is conducted, and the cedar fiber bionic traditional Chinese medicine bonesetting splint is obtained. The cedar fiber is used as a matrix and is cross-linked with the high-molecular low-temperature thermoplastic biological material, the nano inorganic material is combined, and the novel bionic bonesetting splint which is light in weight, breathable, high in longitudinal strength and high in transverse plasticity is prepared through the extrusion and cold pressing technology.

Description

technical field [0001] The present application relates to the field of medical external fixation bone injury treatment devices, in particular to a Chinese fir fiber bionic bone-setting splint and a manufacturing method thereof. Background technique [0002] Medical splints are the most commonly used external fixation devices for the treatment of fractures and have a long history. The ancient Egyptians used linen-wrapped bark to make splints, the ancient Indians used bamboo splints to treat broken bones, and the ancient Greeks used wax and resin to make reinforcing bandages. At present, the medical splints are mainly made of ordinary gypsum splints and polymer materials, supplemented by wooden splints, and various types of fixed medical splints are made according to the difference between the injured parts and their uses. [0003] The use of splints for external fixation in traditional Chinese medicine has a long history. Splint immobilization is an essential and important ...
