SURGICAL DOUBLE PARALLELOGRAM DEVICE

The present invention relates to a surgical double parallelogram device, and to a surgical double parallelogram device in which respective pitch and roll module units form a double parallelogram while pitch- and roll-rotating. To this end, disclosed is the surgical double parallelogram device comprising: a plurality of pitch and roll module units in which each module forms a plurality of stages and which provides two degrees of freedom for each module to be capable of dependently pitch- and roll-rotating; and a plurality of pitch link units connected to the plurality of pitch and roll module units to form a double parallelogram.
