"To feed, a female mosquito uses a complex mouthpart called a proboscis, which contains six specialized needles (stylets).

Two of these needles are serrated saws that slice through your skin, while two others hold the tissue open. A fifth needle searches for a blood vessel and sucks up your blood, while the sixth simultaneously pumps in saliva containing an anticoagulant to keep the blood flowing. "

sounds like robot-surgeon-manipulator from Star Wars/Trek/etc.
