    摘要： An exemplary ultrasound biopsy device includes a probe and a holster. The probe is insertable into the holster to form a completed assembly. To assemble the probe to the holster, the probe is initially slid laterally onto the holster and then slid forward to latch the probe into engagement with the holster. The holster is coupled to a vacuum control module by one or more conduits and a power cable. The conduits and/or power cable may be retracted into the vacuum control module. The probe of the biopsy device includes a blade assembly at the distal end. The blade assembly comprises a blade that snaps onto a nosecone via a pair of resilient notched ends. A frictional fitting needle cover can be inserted over the needle and blade assembly to protect the user from the sharp blade.

    摘要： A method is provided for calibrating a surgical biopsy system. The biopsy system includes a biopsy instrument and control unit. The biopsy instrument includes a piercer, rotatable cutter, and a port for receiving tissue samples. The method comprises the steps of translating the cutter distally until the translation of the cutter is stopped at an extended position and recording the extended position. The cutter is then translated from the extended position proximally until the translation of the cutter is stopped at a retracted position proximal to the extended position. The retracted position is recorded. The method further comprises the step of rotating the cutter to a rotation speed while the cutter is located at the retracted position and, if determined that the rotation speed is within a predetermined rotation speed range, a feedback signal is provided on the display allowing the operator to progress to the next procedural step.

    摘要： A biopsy system with a grid plate used as either a lateral or medial compression plate of a localization fixture used with a breast coil includes a rotatable guide cube that may be inserted into a desired rectangular recess in the grid plate after rotating to position a selected guide hole in the desired spatial orientation. Versions of a guide cube include those rotatable in two axes to provide additional hole positions, angled holes, enlarged circular holes that function with a rotating guide to support a noncircular biopsy instrument cannula (e.g., trocar/sleeve combination, core biopsy probe of a biopsy device) for rotation. A rotating guide may have an unlocked state for easily sliding to a selected longitudinal position thereon. Thereafter, the rotating guide is locked to serve as a positive depth stop (e.g., quarter turn locking elastomeric rings, triangular and scissor clips, and shutter depth stops).

    摘要： A biopsy device includes a body, a needle, and a cutter. A motor is operable to both move the cutter relative to the needle and actuate a needle firing assembly to retract and fire the needle relative to the body. The biopsy device also includes a needle rotation assembly that is configured to substantially prevent rotation of the needle about the longitudinal axis when the needle is in a proximal position yet permit rotation of the needle about the longitudinal axis when the needle is in a distal position. A valve assembly of the biopsy device includes a slider that selectively couples a secondary lumen in the needle with either atmospheric air or saline based on the longitudinal position of the slider. The cutter passes through the slider.

    摘要： A biopsy device includes a cannula and an inner divider wall disposed in the cannula. The inner divider wall defines a plurality of cannula fluid openings. The outer wall of the cannula and the inner divider wall together define a cutter receiving lumen and a cannula vacuum lumen. The cannula fluid openings provide fluid communication between the cutter receiving lumen and the cannula vacuum lumen. A cutter is translatable with respect to the cannula for severing tissue drawn into the cannula. The cutter is operable to cover and/or uncover the cannula fluid openings. A proximal portion of the cutter is spaced away from the inner divider wall. A distal portion of the cutter is configured to slide adjacent to the inner divider wall.

    摘要： A biopsy device and method are provided for obtaining a tissue sample, such as a breast tissue biopsy sample. The biopsy device may include an outer cannula having a distal piercing tip, a cutter lumen, a side tissue port communicating with the cutter lumen, and at least one fluid passageway disposed distally of the side tissue port. The inner cutter may be advanced in the cutter lumen past the side tissue port to sever a tissue sample. After the tissue sample is severed, and before the inner cutter is retracted proximally of the side tissue port, the cutter may be used to alternately cover and uncover the fluid passageway disposed distally of the side tissue.
