    摘要： A method of detecting a leakage current in an electrosurgical system operating at a high frequency includes: coupling an RF generator to a pair of RF output leads via an electrical interface, the RF generator having an operating frequency; inducing a test signal at an output of the electrical interface, the test signal having a test signal frequency that is less than the operating frequency; and monitoring for a presence of an induced common mode current that would indicate the presence of leakage current.

    摘要： A biopsy device includes an elongated probe having a central longitudinal axis, a proximal end, a distal end, and an aperture. A tissue penetrating tip includes a proximal base secured to the distal end of the probe. A sharp distal point distal to the proximal base lies on the central longitudinal axis. Each of a first, second and third concave surface is configured to extend from the base to the sharp distal point. The second concave surface is located to intersect the first concave surface to form a first curved cutting edge. A third concave surface is located to intersect the first concave surface to form a second curved cutting edge and is located to intersect the second concave surface to form a third curved cutting edge. Each curved cutting edge extends from the base to the sharp distal point. A tissue cutting device is coaxial with the probe.

    摘要： A structurally integrated biopsy system includes a movable base having wheels to facilitate movement of the structurally integrated biopsy system. On the movable based there is mounted a tissue removal system, an ultrasound imaging system, and a controller. The tissue removal system includes a probe connector configured to connect to a tissue removal probe. The ultrasound imaging system is configured to generate an ultrasound image of a body region of a patient, and has an image display system having an image display screen to display ultrasound images taken by the ultrasound imaging system. The controller is configured to be in communication with each of the tissue removal system and the ultrasound imaging system to both provide control information for the ultrasound imaging system and provide control information for the tissue removal system in the structurally integrated biopsy system.

    摘要： The invention is directed to a system and device for separating and collecting a tissue specimen from a target site within a patient. The device includes a probe component with an elongated tubular section, a penetrating distal tip and a tissue receiving aperture in the distal end of the tubular section proximal to the distal tip, and a tissue cutting member which is slidably disposed within the probe member to cut a tissue specimen drawn into the interior of the device through the aperture by applying a vacuum to the inner lumen of the tissue cutting member. The device also has a driver component to which the probe component is releasably secured. The driver has a drive member for adjusting the orientation of the tubular section and thus the aperture therein and one or more drive members for moving the tissue cutting member within the tubular section to sever a tissue specimen from tissue extending into the interior of the tubular section through the aperture. The motion imparted to the tissue cutter is at least longitudinal and preferably is also oscillation and/or rotational to effectively separate a tissue specimen from tissue extending through the aperture in the tubular section.
