The present invention discloses a low temperature polypectomy snare surgical device, system and method. The device includes: a liquid input unit, configured to input liquid to a target object in response to a liquid input signal to form a thin layer of a conductive medium between an emission electrode and a loop electrode； a bipolar electrode socket connector, connected with a high frequency generator through a high frequency cable to receive a first input voltage generated by the high frequency generator； the emission electrode, configured to receive the first input voltage generated by the high frequency generator via the bipolar electrode socket connector and apply a first voltage between the emission electrode and the loop electrode.
