[0033] Taking the accompanying drawings as an example, there are five placement holes 37 in the rotating main disk 15, which are distributed at positions A, B, C, D and E respectively. Taking a single placement hole 37 as an example, when the device of the present invention is running, the pushing motor 42 in the pushing member 41 in the powder pushing member 7 starts to run, the pushing spindle 43 rotates, and the pushing blades 44 rotate along with the pushing spindle 43. The powder moves from the powder placement tube 39 to the docking tube 40 along with the pushing blades 44, and falls into the placement hole 37 position A of the rotating main disk 15. When the drive motor 33 is running, the drive shaft 34 rotates, and the drive gear 35 engages with the connecting gear 38.

The bottom plate of the pressing plate 48 presses the powder. When the placement hole 37 moves from position B to position C, the upper edge of the placement hole 37 fits the arc edge of the bottom surface of the pressing plate 48, and the pressing column 49 is inserted in the telescopic tube 47. The drag spring 50 is pressed The top surface of the plate 48 and the bottom surface of the transverse extension plate 45 are squeezed, and the bottom surface of the pressing plate 48 is in contact with the top surface of the rotating main disk 15 until the placement hole 37 moves to position C. At this time, the powder in the placement hole 37 is in a compressed state. When the placement hole 37 moves to position D, the suction pump 54 and the push pump 52 operate synchronously. The push pump 52 pushes a certain amount of mixed liquid in the mixed liquid connecting pipe 53 to the push pipe 51, and then enters the bottom stabilizing pipe 21 of the pressurized liquid inlet component 13. As the mixed liquid is pumped in, the sliding top plate 27 slides upward along the guide column 26 in cooperation with the sliding hole 32 and the guide column 26. The mixed liquid flows through the passage between the guide columns 26 and enters the liquid inlet stabilizing tube 20. The puncture needle group 31 on the top surface of the sliding top plate 27 is inserted into the powder, and the auxiliary mixed liquid flushes the mixed medicine in the placement hole 37 until the mixed liquid and powder are fused and enter the suction cavity 55 through the filter screen 56. Under the operation of the suction pump 54, the mixed liquid medicine passes through the one-way valve plate A57 and enters the side discharge pipe 58. It enters the puncture needle connecting pipe 11 through the one-way valve plate B59. Under the synchronous operation of the push pump 52 and the suction pump 54, a quantitative mixed liquid medicine is pushed into the medical puncture device to complete the quantitative push of the medicine inside the tumor.

[0034] When the push pump 52 and the suction pump 54 stop operating simultaneously, the sliding top plate 27 moves downward and resets under the joint action of the sliding support column 28 and the support spring 30, and the liquid level below the one-way valve plate A57 moves down and falls back into the liquid inlet stabilization tube 20, and the placement hole 37 moves from position E to position A again.

[0035] The above is the overall workflow of the present invention. Just repeat this step next time you use it.
