  • Apparatus for light beam guided biopsy
    Patent number: 6443960
    Abstract: An apparatus for assisting percutaneous light beam guided biopsy, having means for rotating a laser device about first and second rotation axes, the laser device providing its laser beam along an axis intersecting an intersection point between the first and second rotation axes and at right angles thereto. Inclinometers are installed for providing signal values as a function of two- or three-dimensional orientation directions of the said laser device relative to direction of gravitation. Encoding means provide feedback of rotary position information of the laser device. Comparing means compare set calculated instrument insertion angle values, provided from an input device, with encoder feedback signals and inclinometer signals and inhibits rotation operation of the laser device upon reaching specific threshold values.
