Zusammenfassung:A biopsy device includes a body, a needle, a cutter, and a needle rotation assembly. The needle extends distally from the body and includes a tip and a transverse aperture proximal to the tip. The needle defines a longitudinal axis, wherein the needle is translatable relative to the body along the longitudinal axis. The needle is selectively rotatable relative to the body about the longitudinal axis. The cutter is moveable relative to the needle to sever tissue protruding through the traverse aperture. The needle rotation assembly is configured to prevent rotation of the needle about the longitudinal axis when at least a portion of the needle rotation assembly is in a first longitudinal position relative to the body, wherein the needle rotation assembly is further configured to permit rotation of the needle about the longitudinal axis when at least a portion of the needle rotation assembly is in a second longitudinal position relative to the body.
