The invention provides a stirring syringe for adding bioactive factors or medicines. The stirring syringe comprises an injection main pipe, a flow mixing pipe and a push rod, wherein the injection main pipe is internally and longitudinally provided with multiple cavities; one end of the flow mixing pipe is hermetically connected with one end of the injection main pipe, the other end of the flow mixing pipe is provided with an injection head; the flow mixing pipe is internally provided with at least one screw panel; the flow mixing pipe is divided into multiple communicated screw channels; one end of the push rod is provided with multiple plungers; the quantity of the plungers is consistent with that of the multiple cavities. The multiple screw panels are arranged in the flow mixing pipe, so that, after being pressed into the flow mixing pipe by virtue of the plungers, the bioactive factors or medicines in a specific proportion filled in the different cavities of the syringe are fully mixed under the action of the multiple screw panel and then injected to a specific position of a human body once. The stirring syringe is simple in structure and convenient in use, can be used for fully mixing various bioactive factors or medicines and improving the treatment effect, and has higher medical value.
