    Abstract: A fine needle aspiration device with a modified handle and cannula through which a vacuum is delivered to the targeted tissue for removal of liquid or cellular samples is provided, the vacuum being provided via a flexible tubing capable of fitting within a restricted space such as, for example, a CT gantry. A vacuum source may be provided to assist the fine needle aspiration procedure via flexible tubing, which allows the vacuum source to be located outside the CT gantry or on the patient.

    Abstract: The present invention is intended to provide a tissue biopsy needle apparatus equipped with a protective cover which prevents a needle tube from being ejected unnecessarily when an urging member is compressed in preparation for ejection of the needle tube. For that, the tissue biopsy needle apparatus includes a spring 28 which ejects the needle tube 26; a drawing unit which draws the spring 28 to a compressed position, the drawing unit including a drawing knob 20 and a drawing tube 29; an operation switch 24 which causes the drawing unit to draw and hold the spring 28 at the compressed position and causes the spring 28 to be released from the compressed position, thereby ejecting the needle tube 26; a protective cover 23 which disables the operation switch 24 when the spring 28 is drawn and held at the compressed position; and an elastic tongue 23c and an abutting strip 29b which move the protective cover 23 from a working position to a non-working position of the operation switch 24 in accordance with drawing of the spring 28 to the compressed position by the drawing unit, the elastic tongue 23c being installed on the protective cover and the abutting strip 29b being installed on the drawing tube 29.

    Abstract: A biopsy device and method are provided for obtaining a tissue sample, such as a breast tissue biopsy sample. The biopsy device includes a disposable probe assembly with an outer cannula having a distal piercing tip, a cutter lumen, and a cutter tube that rotates and translates past a side aperture in the outer cannula to sever a tissue sample. The biopsy device also includes a reusable hand piece with an integral motor and power source to make a convenient, untethered control for use with ultrasonic imaging. The reusable hand piece incorporates a probe oscillation mode to assist when inserting the distal piercing tip into tissue. A straw stacking assembly is automatically positioned by the reusable hand piece to retract multiple samples with a single probe insertion as well as giving a visual indication to the surgeon of the number of samples that have been taken.

    Abstract: It is an object of the present invention to drastically reduce the likelihood of failure in sampling biological tissue. The solution means is a biopsy needle device (1) constructed in a manner such that an internal needle (2) is triggered in response to unlocking operation of internal needle locking means (8), after which a piston (14) is retracted by a piston retraction spring (15) in response to unlocking operation of piston locking means (16), whereby negative pressure is generated in a recess (2a) of the internal needle (2) resulting in suction of biological tissue into the recess (2a), and an external needle (3) is triggered in response to unlocking operation of external needle locking means (9), thereby cutting and sampling the biological tissue which has been drawn into the recess (2a).

    Abstract: Biopsy devices are presented comprising: an inner needle comprising a tip for piercing tissue, and a cavity for receiving a tissue portion; an outer sheath moving with respect to the inner needle between a forward position of the sheath in which it totally covers the cavity and a backward position in which the cavity is totally uncovered, the outer sheath comprising a cutting edge at its front end configured to cut the tissue portion into the cavity while moving in a forward direction; and at least one of: a sensing unit mounted on the outer sheath such that the sensing unit is aligned with the cavity when the sheath is in the forward position to thereby sense tissue signals from the tissue portion; or a suction system for applying suction force in the cavity to pull the tissue portion into the cavity while the sheath moves in a backward direction.

    Abstract: The present invention relates to an arrangement for taking a biopsy in a human or animal tissue, comprising an elongated hollow member having a circular cross-section in a plane perpendicular to a longitudinal axis, and a circular cutting edge (31) at a distal end. The circular cutting edge is provided with at least one cutting slit (32), running from the cutting edge in a proximal direction of the elongated hollow member. The arrangement further comprises a rotational member configured to apply rotational movement to the hollow member, wherein the rotational movement is applied in accordance to a rotational procedure such that the hollow member is rotated in one direction a predefined amount of rotations, and thereafter rotated in an opposite direction the same amount of rotations.

    Abstract: An excisional device may comprise a work element configured to rotate at a first rotation rate and comprising a first and a second articulable beak configured to cut tissue. A first helical element, configured to transport tissue cut by the first and second articulable beaks, may be co-axially disposed relative to the work element and operative to rotate at a second rotation rate that is different than the work element. A proximal sheath may be co-axially disposed relative to the work element and the first helical element, and may be configured to rotate the work element and to actuate the first and second articulable beaks.
