Abstract
An automated tissue sampling device is disclosed which permits its needles to be cocked either simultaneously or sequentially and can be cocked with only one hand. The cocking mechanism is arranged so as to virtually eliminate the possibility that the needles will be cocked in the wrong sequence. The physician can readily confirm, either visually or tactilely, whether the device is uncocked, half cocked, or fully cocked. The disclosed tissue sampling device also comprises two different trigger buttons, one adjacent the front end of the device and the other at the rear, and manipulating either of the two trigger buttons will actuate the device.
