The invention discloses a manufacturing method for a
corrosion-resistant orthopedic degradable screw. The manufacturing method comprises the following steps that (1) a degradable
metal bar, a female die and a
stamping male die are provided, an open conical die cavity is formed in the female die, the other side of the die cavity communicates with an overflow hole, and the
stamping male die is provided with a tip; (2) the degradable
metal bar is placed in the die cavity of the female die, the
stamping male die is operated to
impact the degradable
metal bar, the stamping male die impacts a groove in the degradable metal bar in the
impact process, and a part of metal flows outsides from the overflow hole; and (3) the orthopedic screw is obtained in the die cavity through repeated impacting for a certain time for multiple times. According to the manufacturing method, through cooperation of the female die and the stamping male die, the degradable metal bar is hammered and stamped for multiple times to obtain the orthopedic screw which is of a compact structure and good in mechanical properties, so that the
corrosion resistance of the orthopedic screw is improved, the degradation rate is low after the orthopedic screw is implanted into a
human body, the process is simple, and the cost is low. The invention further provides the
corrosion-resistant orthopedic degradable screw manufactured by the method.
