When the rotating block 16 rotates, it drives the puncture device 3 to rotate simultaneously until the appropriate angle is reached. Then, the second motor 20 inside the top plate 1 is started, driving the first threaded rod 21 to rotate. When the first threaded rod 21 rotates, it drives the moving block 10 to move along the outside of the first threaded rod 21 until it moves above the puncture site of the patient. Then, the second motor 20 is stopped, and the puncture device 3 is started to perform puncture.
[0041] When it is necessary to fix the position of the device, first align the bottom end of the upper clamping plate 23 at the bottom of the support rod 2 with the top of the bed board, and at this time the lower clamping plate 28 is below the bed board. Then turn the handle 26 to drive the second threaded rod 25 to rotate, and the bottom end of the second threaded rod 25 rotates along the inside of the second fixing block 24. At the same time, it drives the moving frame 27 to move upward along the surface of the second threaded rod 25, and at the same time, it drives the lower clamping plate 28 to move upward. When the moving frame 27 moves, it also moves along the outside of the guide rod 29 until the upper clamping plate 23 and the lower clamping plate 28 clamp the bed board. The anti-slip sliders 30 at the bottom end of the upper clamping plate 23 and the top end of the lower clamping plate 28 can effectively prevent slippage and achieve an anti-slip effect.
