Healing assistance injection needle tube

The invention relates to a healing assistance injection needle tube comprising a needle tube body, wherein the outer surface of the needle tip of the needle tube body is coated with a growth factor layer promoting wound healing. According to the invention, a growth factor promoting wound healing and a needle tube lubricant coat the surface of the needle tube, wherein a growth factor promoting wound healing and a needle tube lubricant are attached to the surface of the needle tube in a layered manner, or a growth factor promoting wound healing and a needle tube lubricant coat the surface of the needle tube in a mixed manner, or a lubricating growth factor promoting wound healing coats the surface of the needle tube. After the needle tube punctures the skin and completes injection, the growth factor stays on the surface of the wound. The needle tube has a lubricating effect when puncturing the human body, so that the pain of patients is reduced, and the needle hole stopping bleeding can heal quickly.
