摘要： A biopsy device includes a needle extending distally from a body. The needle includes a transverse aperture, a first lumen, and a second lumen. A cutter is movable within the first lumen to sever tissue protruding through the transverse aperture. A valve assembly is operable to change the pneumatic state of the second lumen. The valve assembly includes a valve body and a translating member slidably disposed in a bore of the valve body. The valve body includes a first port and a second port. The first port is in fluid communication with the second lumen of the needle. The second port is in fluid communication with atmospheric air. The translating member selectively couples the first port with the second port based on the longitudinal position of the translating member within the bore. The translating member translates relative to the valve body based on the position of the cutter.

摘要： 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.

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： An instrument for deploying a marker at a site within a patient may include an elongate cannula, an elongate pusher, and a marker disposed within the cannula. The cannula may have a tip at its distal end and a transverse opening. The pusher may be disposed within the cannula, and may be moved longitudinally within the cannula. The pusher may have a ramped distal end. The marker may be configured to exit the transverse opening upon urging by the ramped distal end of the pusher. In some versions, the tip of the cannula has a flat proximal face, and the marker has a recessed region that is configured to buckle in response to longitudinal compression, such that the marker will pop out of the cannula upon buckling. In other versions, the cannula has an external sheath, an open and curved distal end, or a leaf spring.

摘要： An ultrasonic medical instrument having a handpiece and medical ultrasonic blade assembly including a vibration antinode, a handpiece, and a medical ultrasonic blade. The blade is threadably engaged by the handpiece proximate the vibration antinode. The blade is in ultrasound-transmitting physical contact with the handpiece proximate the vibration antinode and apart from where the medical ultrasonic blade is threadably engaged by the handpiece. A medical-instrument connection assembly for transmitting ultrasonic vibrations includes first, second, and third connecting members. The first connecting member is adapted to be ultrasonically vibrated and has a longitudinal axis. The second connecting member is capable of being positioned to be substantially coaxially aligned with the longitudinal axis and in ultrasound-transmitting physical contact with the first connecting member. The third connecting member surrounds, and is rotatably or fixedly attached to, the second connecting member and is threadably engageable with the first connecting member.
