Abstract

The invention relates to a high-strength and high-antibacterial absorbable suture line. The suture line is prepared from the following components in parts by mass: 80-100 parts of a polyglycolic acidnano material, 15-25 parts of chitosan, 3-5 parts of polyethylene glycol, 2-3 parts of cinnamon oil and 2-3 parts of mannitol. A preparation method of the polyglycolic acid nano material comprises thefollowing steps: uniformly mixing graphene oxide, polyethylene glycol and an organic solvent and carrying out ultrasonic dispersion to obtain a graphene oxide dispersion liquid A, adding the mixed solution A into an organic solvent of chloroacetic acid, performing uniform stirring to obtain a mixed solution B, dropwise adding an organic solvent of triethylamine into the mixed solution B at a lowtemperature, gradually performing heating until a reflux reaction is completed, performing concentrating to remove the solvent to obtain a mixture C, washing the mixture C with an alcohol compound toobtain a polyglycolic acid nano material crude product D, and carrying out forced air drying on the polyglycolic acid nano material crude product to obtain the polyglycolic acid nano material. The high-strength and high-antibacterial absorbable suture line prepared by the method disclosed by the invention has the advantages of high tensile strength, firm knotting, good biocompatibility, no adversereaction in a human body and lasting antibacterial performance.

Description

technical field [0001] The invention relates to a high-strength and high-antibacterial absorbable suture, which belongs to the technical field of polyglycolic acid nano-medical suture processing. Background technique [0002] Medical sutures are widely used in surgery and play an important role in promoting wound healing. The medical sutures used in the prior art can be divided into two categories, one is absorbable sutures and the other is non-absorbable sutures. For non-absorbable sutures, the process of removing them can be quite painful for the patient. Absorbable sutures have the obvious advantage of lessening the pain of stitch removal. After the patient's wound is healed, there is no need to remove the suture, and it can be left in the human body to absorb and degrade. However, absorbable sutures in the prior art have a high probability of allergic reactions in the human body, and some sutures require special antibacterial agents to be treated to achieve better ant...
