摘要
The present disclosure relates to a method of manufacturing a needle for root canal treatment devices having improved ductility. The method of the present disclosure includes a step of manufacturing a hollow needle body in a desired shape using an alloy or a single metal, a step of filling the hollow of the needle body with a packing member, a step of heat-treating the needle body at a predetermined temperature under an inert gas atmosphere after the needle body is placed in a vacuum chamber, and a step of cooling and hardening the needle body.
