العنوان: (EN) Method for preparing absorbable biological material artificial blood vessel bracket using electro-spinning
(ZH) 一种采用静电纺制备可吸收生物材料人工血管支架的方法
الملخص:
(EN) The invention relates to a method for preparing an absorbable biomaterial artificial intravascular stent with electrostatic spinning, which comprises the steps of: (1) preparing a 10 - 20 percent (g/ml) polymer spinning solution; (2) preparing a nano cellosilk by using the solution prepared with an electrostatic spinning technology, with parameters under control; and (3) collecting the prepared cellosilk as a tubular stent with a roller receiving unit. The method is simple and takes a short time. The artificial vessel prepared by the method has good growth activity after being transplanted into a human body and smooth muscle cell can grow along and get into the fiber.
