一种植入型氰基丙烯酸酯医用胶制备方法及其应用
By employing low-temperature supercritical gradient extraction, molecular imprinting adsorption, and membrane separation technologies, combined with byproduct resource-based modification, the problems of high-temperature polymerization and incomplete impurity removal in the purification of existing cyanoacrylate medical adhesives have been solved. This has resulted in the preparation of a high-purity, low-residue, and biocompatible medical adhesive suitable for implantable surgical procedures and in vivo wound repair.

AI Technical Summary
Existing purification processes for cyanoacrylate medical adhesives often result in high-temperature polymerization of monomers, poor selectivity in impurity removal, excessive solvent residue, substandard biocompatibility, waste of byproducts, and poor batch stability, making it difficult to meet implant-grade purity and safety requirements.
By employing low-temperature supercritical gradient extraction, molecularly imprinted selective adsorption, and membrane separation technologies, combined with byproduct resource utilization modification, multi-stage purification and stabilization continuous operation is achieved to prepare high-purity, low-residue, and biocompatible medical adhesives.
The preparation of high-purity cyanoacrylate medical adhesive has been achieved, avoiding the risks of high-temperature polymerization, improving biocompatibility and stability, reducing environmental pollution, lowering production costs, and making it suitable for implant-grade use.
