An improved disposable single-hand controlled aspirating device for medical aspirating activities most particularly fine needle biopsy procedures. The aspirating device includes a syringe barrel, a plunger operative in the barrel, and a finger grip assembly that is mounted to the syringe barrel and plunger for controlling plunger movement within the barrel. The finger grip assembly includes a body member and a trigger member slidably engaged within the body member. More specifically, the finger grip assembly resembles a pistol-like handle and trigger arrangement that enables a user of the device to control plunger movement in the syringe barrel with a single hand.
