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 having a piecing tip, a tissue receiving aperture and a vacuum lumen; a cutter within the probe having a cutting edge that moves past the tissue receiving aperture, 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.

摘要： Devices and methods for varying the size of a tissue sample in a biopsy device are disclosed. The biopsy device includes a needle with a tissue aperture and an inner cutter which translates within the needle. The inner cutter may be controlled to selectively block the aperture thereby varying the sample size. A half cylindrical sleeve may be resiliently attached to the exterior of the needle in order to block the aperture. The sleeve includes gripping flanges on its bottom surface, and a beveled distal tip configured to avoid damage from the inner cutter. The distal tip may include an inner metallic guide or may be heightened to avoid contact with the cutter.
