摘要
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a biopsy needle assembly, wherein when a motor is operated to rotate the cutter forward and backward, the motor rotation is stopped and the momentary load is reduced during initial operation to reduce the inrush load of the motor. The present invention relates to a structure of a biopsy needle assembly for reducing the starting load to improve vibration and noise during the procedure and to minimize lesion irritation.
