Surgical system, processor and control method

A processor that controls an endoscope including an imager which captures an endoscopic image, and a drive device which controls a medical manipulator with an injection needle at a distal end section thereof to control a position of the injection needle,

• wherein the processor is configured to:
• control to inject a target amount of a injection fluid into a syringe connected to the injection needle;
• acquire, from the imager, the endoscopic image in which a treatment target is captured;
• and
• perform a prescribed determination to determine success/failure of injection using the endoscopic image, and control the drive device to change the position of the injection needle based on a determination result of the prescribed determination.
