    摘要： The present invention provides a biopsy instrument with improved needle penetration for piercing dense tissue. The device may comprise a needle slidably retained in a housing. The device may further comprise an actuation member that may be adapted to communicate longitudinal motion to the needle in a first direction. The device may further include a propulsion element that provides the needle with return motion in a second direction. The device may be fired multiple times to create repeating reciprocal motion. In one version, the device may reciprocate several times as a result of a single engagement of the actuation member.

    摘要： A medical device for severing and removing small amounts of internal tissue for biopsy sampling or other purposes is disclosed. Versions of the device may include a hollow probe (24) having a piercing tip (32), a tissue receiving aperture (27) and a vacuum lumen; a cutter (33) within the probe having a cutting edge (35) that moves past the tissue receiving aperture (27), and a cutter driver mechanism. A cutter for use with versions disclosed herein may include an angled cutting tip and a cutting edge having a concave grind. Versions of the device also may include an aspirator fluidly connected to the vacuum lumen, coordinated operation of the aspirator and the cutter driver mechanism, and a fluid management system. Versions described may be used for removing multiple samples of tissue during a single insertion of the probe proximate to a target tissue mass.
