  • Biopsy needle assembly for reducing starting load when motor changes direction
    Patent number: 11471136
    Abstract: The present invention relates to a biopsy needle assembly and, more specifically, to a structure of a biopsy needle assembly for reducing a starting load which improves vibration and noise during a procedure and minimizes irritation to a lesion by, when a motor is operated to move a cutter forward/backward while rotating the cutter, stopping motor rotation and reducing an instantaneous load during an initial operation so as to reduce a firing (starting) load of the motor.
