A biopsy needle for collecting a tissue specimen includes a housing; an outer cannula that is at least partially received within the housing; and an inner tube received within the outer cannula and is configured to receive a stylet. The needle also includes a snare coil that is formed as part of the inner tube and is coupled to the outer cannula. The needle has a first actuation stage and a second actuation stage that is automatically activated as a result of activation of the first actuation stage. During the first actuation stage, a first mechanism contained at least partially within the housing is actuated to longitudinally and axially advance both the outer cannula and the inner tube as well as causing the outer cannula and the inner tube to simultaneously rotate in unison as the two are longitudinally advanced. In the second stage, a second mechanism contained at least partially within the housing is actuated to cause rotation of the inner tube relative to the outer cannula thereby causing activation of the snare coil.
