Abstract

The invention discloses a functional fixing plate. The functional fixing plate is produced from the following raw materials, by mass, 0-90% of poly(epsilon-caprolactone), 0-90% of a thermoplastic elastomer, 0(exclusive)-15% of nanometer functional powder, and 0(exclusive)-5% of a crosslinking assistant; and the contents of poly(epsilon-caprolactone) and the thermoplastic elastomer cannot be 0 simultaneously. The functional fixing plate has good comfortableness and fixing strength, has antibiosis, far-infrared, negative ion, magnetism, heat accumulation and cooling functions, can prevent wound infection, promote and improve blood circulation, improve human body immunity, mitigate fatigue and improve the comfort level of patients, has anti-inflammation, detumescence, pain easing and wound healing promotion effects, and is suitable for being used in bone fixation and radiotherapy processes.

Description

technical field [0001] The invention relates to a functional positioning board, in particular to a medical shape-memory low-temperature thermoplastic functional positioning board with one or more functions of antibacterial, far-infrared, negative ions, magnetic therapy, heat storage or cooling. method and its use. Background technique [0002] Shape memory materials refer to the stimuli that can perceive environmental changes (such as temperature, force, electromagnetic, solvent, etc.), and adjust their mechanical parameters (such as shape, position, strain, etc.) in response to such changes, so as to return to their previous state. The material that sets the state. As a new type of material, shape memory polymer material has the advantages of good biocompatibility, moderate induction temperature, large recoverable deformation, easy processing and molding, etc., and has attracted much attention in the field of biomedicine. [0003] Low-temperature thermoplastic shape memor...
