The invention discloses a human body absorbable surgical suture thread and a preparation method thereof. The preparation method comprises the following steps: S1, twisting human body absorbable phosphate glass fiber strands into phosphate glass fiber strands; S2, combining Phosphate glass fiber strands and one or more of polylactic acid strands, ε-polycaprolactone strands, and polyglycolide strands are twisted together to obtain surgical sutures that can be absorbed by the human body . The invention adopts phosphate glass fiber which can be absorbed by the human body as the main wire material. The unique degradability enables it to be completely degraded and absorbed by the human body. During the degradation process, calcium, magnesium, phosphorus, and sodium are continuously and slowly released trace elements necessary for tissue repair. , indirectly promote wound healing without causing human rejection or allergic reactions. |
