The working principle is as follows: when the sampling and storing device for lung cancer is used, the puncture needle tube 1 is driven to move axially and further can be smoothly punctured into the body of a patient, before the lung cancer enters the body, the high-pressure gas is filled in the gas guide cavity 5 in the puncture needle tube 1 and extrudes the piston ring 4 in the cavity in the truncated cone-shaped sleeve 2, so that the piston ring 4 can drive four non-complete conical arc plates 3 to continuously extend and move at the end part of the truncated cone-shaped sleeve 2, the four non-complete conical arc plates 3 continuously move and extend to form a conical pointed end, the puncture needle tube 1 can more easily enter the body of the patient through the arrangement of the conical pointed end until the lung cancer punctures into a target object, wherein the piston ring 4 is an elastic rubber piston ring and has good elasticity, and after being arranged in the truncated cone-shaped sleeve 2, the space in the truncated cone-shaped sleeve 2 can be divided into two independent spaces, and high-pressure gas leakage can not occur, and in the practical use process, a spring for accelerating the reset of the piston ring 4 and the incomplete conical arc plate 3 can be arranged in the cavity of the truncated cone-shaped sleeve 2, and the spring is parallel to a bus of the truncated cone-shaped sleeve 2.

After the puncture enters the target object, the high pressure in the air guide cavity 5 is released immediately, and the piston ring 4 and the incomplete conical arc plate 3 can be reset synchronously under the action of the spring; the channel at one end of the truncated cone-shaped sleeve 2 far away from the puncture needle tube 1 is released and exposed and opened;

according to the invention, after the puncture needle tube 1 completes puncture by utilizing the incomplete conical arc plate 3 and the circular truncated cone-shaped sleeve 2 at the end part and moves to a target position, the sampling needle core 7 is driven to axially move first, the sampling needle core 7 moves rightwards along with the synchronous ring 10 on the sampling needle core 7 in the process of moving rightwards, and the top of the limiting ejector rod 13 limits the movement of the guide frame 9, so that the first compression spring 11 is continuously extruded and contracted in the process of moving rightwards of the sampling needle core 7 until the elastic potential energy accumulated by the first compression spring 11 breaks through the elastic potential energy of the second compression spring 14, and the limiting ejector rod 13 moves downwards, and then the locking of the guide frame 9 is released;

under the action of the elastic force of the first pressure spring 11, the guide frame 9 moves rightwards on the sampling needle core 7, and then after the left end of the excision tube 6 is contacted, the excision tube 6 can immediately and rapidly move rightwards, so that the sampling needle core 7 and the excision tube 6 can successively move rightwards, the movement time difference exists, the sampling needle core 7 and the excision tube 6 can successively extend out of the channel on the circular truncated cone-shaped sleeve 2 and enter a target position in a patient body, and the puncture sampling of a target tumor is further completed.

The puncture needle tube 1 is moved by arranging the auxiliary device I;

the driving mechanism is provided to move the entire horizontal slider 20, thereby moving the puncture needle tube 1.

The adjustment of increase and decrease of the air pressure in the air guide cavity 5 and the steering of the roller 27 can be realized through the arrangement of the adjusting mechanism;

by means of the arrangement of the excitation device, a final axial displacement of the sampling needle core 7 and the cutting tube 6 in succession is achieved.
