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 handpiece with an integral motor and power source to make a convenient, untethered control for use with ultrasonic imaging. The reusable handpiece incorporates a probe oscillation mode to assist when inserting the distal piercing tip into tissue. The motor also actuates an attached sample revolver drum assembly in coordination with movement of the cutter tube to provide sequentially stored tissue samples in a sample storage bandolier that is rotated about a revolver cylindrical drum.

摘要： An ultrasound medical system includes a handpiece and an end effector which is operatively connected to the handpiece and which is insertable into a patient. The end effector includes a shaft, a medical ultrasound transducer assembly, and a shaft head. The shaft has a longitudinal axis, has a distal end, and is rotatable about the longitudinal axis with respect to the handpiece. The transducer assembly is non-rotatably attached to the shaft and is adapted to emit medical ultrasound. The shaft head is attached to the distal end of the shaft and has a piercing tip which is insertable into patient tissue.

摘要： A surgical dissector comprising an elongate shaft having a proximal end and a distal end. A blunt dissection tip is positioned on the distal end of the elongate shaft. A light source emits a diffuse visible energy, such as white light, from the blunt tip. The shaft may take a variety of shapes, including being rigid, flexible, malleable, straight, bent, curved, articulated, and/or segmented. In addition, the shaft may include one or more functional components. The dissector can be used to locate the dissector tip by observing the visible energy passing through tissue. In addition, the visible energy passing through tissue may be used to differentiate tissue.
