Abstract: 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.

Abstract: A disposable, single-hand controlled aspirating device for medical aspirating activities such as subcutaneous biopsy of fluid, soft tissue and bone marrow is provided. The aspirating device includes a syringe barrel, a plunger operative in the barrel, a finger grip member surrounding the exterior wall of the barrel that includes a collar portion engaging the exterior wall of the barrel and flange portions extending outwardly from the exterior wall of the barrel a distance sufficient to provide support for a user's fingers during aspiration procedures, and a spring surrounding the plunger portion external to the barrel for biasing the plunger outwardly from the barrel after the plunger has been advanced in the barrel toward the distal end thereof.
