The present application is directed to an image-guided, vacuum assisted, percutaneous, coring, cable driven breast biopsy instrument which may be conveniently mounted to an x-ray machine wherein the biopsy instrument incorporates a rotation knob at the proximal end of the instrument to manually rotate the distal end of the probe, thus allowing the clinician to conveniently position the tissue port next to the tissue to be sampled.

Biopsy device with strainer

A biopsy device includes a body portion, a tip, at least one blade, and a cutter. The cannula defines at least one lumen. The cannula has a transverse aperture configured to receive tissue. The tip is located at the distal end of the cannula, and may include at least two concave surfaces. The blade extends longitudinally from the tip. A second blade may also extend longitudinally from the tip. Blades may be axially staggered relative to the cannula. Blades may also have lengths that differ from one another. In addition, a blade may have a pointed distal end, or may have a curved distal edge. The configuration of the blade and tip may provide reduced force to penetrate tissue. The blade and tip may produce a cut length that is greater than or equal to the length of the outer perimeter of the cannula.

Needle tip for biopsy device

A biopsy device and method may be used to obtain a tissue sample, such as a breast tissue biopsy sample. The biopsy device includes an outer cannula having a distal piercing tip, a cutter lumen, and a cutter tube that is rotated by an integral motor and manually translated past a side aperture in the outer cannula to sever a tissue sample. A sample capturing structure (e.g., sample barrel) has a plurality of sample cavities (e.g., radially symmetric, revolver handgun orientation) that are manually aligned one at a time to capture one or more samples.

Manually rotatable piercer

A biopsy marker introduction assembly is configured for introduction through a specimen retrieval recess into a probe cutter lumen of a handheld breast biopsy handle. Advancing the cutter causes an extending deployment rod to distally translate within an introducer tube of the introduction assembly, pushing a biopsy marker out of a distal end of the probe at a surgical biopsy site. Thereby, the surgeon is able to position the probe and effect deployment of the marker even if using the other hand to position an imaging device such as an ultrasonic transceiver.

The invention described herein is an image-guided, vacuum assisted, percutaneous, coring, cable driven breast biopsy instrument which may be conveniently mounted to an x-ray machine. The biopsy instrument described herein incorporates incorporates a firing mechanism to rapidly advance the biopsy probe into the breast.

The present application describes an image-guided, vacuum assisted, percutaneous, coring, breast biopsy instrument which may be conveniently mounted to an x-ray machine, and incorporates a safety lockout system that is located at the proximal end of the biopsy instrument.

Lockout for a surgical biopsy device

The present invention is directed to an improved cable driven surgical biopsy device wherein a transmission assembly is disposed at a proximal end of the biopsy device. The transmission assembly being adapted to convert rotational motion of a cable entering the biopsy device of a substantially right angle into rotational energy to drive the axial cutter in the biopsy device.

Transmission assembly for a surgical biopsy device

A surgical instrument having an elongated shaft to which is attached an inflatable balloon, commonly referred to a 'balloon dissector', for dissecting a desired layer of internal bodily tissue from remaining tissue layers to create an operative space is disclosed. Alternatively, an instrument without a balloon can be used to perform a manual dissection. In one embodiment, the instrument has a tissue-contacting element in communication with the shaft distal end, and at least a portion of the tissue-contacting element is transparent. The instrument is adapted to receive an endoscope through its shaft and extend to adjacent the tissue-contacting element. The endoscope is supported and positioned in an extension assembly. The instrument provides for visualization using the endoscope as the instrument is advanced through tissue, but prevents direct contact between the tip of the endoscope containing the lens and the tissue. The extension assembly also enables the endoscope to be adequately positioned and supported beyond the shaft distal end. When the instrument incorporates the balloon, the endoscope can extend into the lumen of the inflated balloon. In this way, improved visualization during use can be obtained.
