The invention relates to the technical field of
medical equipment, and provides a sampling device facilitating tumor separation and a
separation method thereof.The sampling device comprises a needle tube, the top of the needle tube is fixedly connected with a tube
barrel, one end of the top of the tube
barrel is fixedly connected with an electric telescopic rod, and the output end of the electric telescopic rod is fixedly connected with a movable plate; a sampling mechanism is arranged at the bottom end of the movable
pipe and comprises a pressing rod, a plurality of
cutting knives are rotationally connected to the outer side of the bottom of the movable
pipe, a plurality of connecting rods are rotationally connected to the bottom end of the pressing rod, and the ends, away from the pressing rod, of the connecting rods are rotationally connected with the middles of the corresponding
cutting knives; the top end of the pressing rod is fixedly connected with a pressing block, the middle of the movable
pipe is fixedly connected with a
piston, and the other end of the top of the pipe
barrel is provided with a driving piece. According to the invention, the
cutting range of the cutting knife can be greatly increased, and large-size tumor tissues can be obtained to provide enough samples for subsequent detection work.
