[0022] A fixed cylinder 8 is installed in the inner cylinder 7, and a puncture needle 81 is installed below the fixed cylinder 8. The puncture needle 81 passes through the bottom of the inner cylinder 7. The fixed cylinder 8 controls the puncture needle 81 to extract the effusion in the patient's pericardium.

[0023] Through the structure of the fixed tube 8, after the puncture needle 81 penetrates into the patient's body, the effusion in the pericardium is extracted.

[0024] A rotating disk 11 is rotatably connected to the bottom of the bracket 1, and the rotating disk 11 is transmission-connected to the motor above the bracket 1 through a shaft. The shell 2 is fixedly connected to the bottom of the rotating disk 11, and the interior of the shell 2 is arranged as a cavity structure. A swing groove 21 is arranged at the bottom of the shell 2, and a first rack 3 is horizontally slidably connected to the middle part of the upper part of the shell 2, and a tooth block of the first rack 3 is located below it. A slide groove 31 is arranged in the middle part of one side of the first rack 3, and a sliding column 32 is inserted into the slide groove 31. The sliding column 32 is horizontally slidably connected to the slide groove 31 of the first rack 3, and the other end of the sliding column 32 is fixedly connected to the inner wall of the shell 2.

[0025] The motor drives the rotating disk 11 to rotate under the bracket 1, so that the housing 2 drives the puncture needle 81 to adjust the direction. The outer cylinder 52 can swing horizontally through the structure of the swing slot 21, thereby increasing the diversity of the direction adjustment of the puncture needle 81, making it suitable for patients in different conditions.

[0029] Under the elastic force of the first spring 41, the positioning rod 4 pops out into the positioning slot 34 to prevent the positioning rod 4 from moving out of the positioning slot 34 during use, thereby causing the first rack 3 to change position; When the position of the first rack 3 needs to be adjusted, the pull block 43 is pulled outward so that the first connecting rope 42 drives the positioning rod 4 to retract into the shell 2, and the connecting column 33 can slide horizontally, thereby controlling the horizontal sliding of the first rack 3 through the connecting column 33.

[0030] A first gear 5 is provided below the first rack 3, and the first rack 3 is meshed with the first gear 5 for transmission.

[0031] The first gear 5 is controlled to be selected by horizontal sliding of the first rack 3, and the outer cylinder 52 is controlled to adjust the angle in the swing groove 21 by rotating with the rotating shaft 51 as the center; The structure of the first telescopic rod 53 is used to control the sliding distance of the inner cylinder 7 in the outer cylinder 52 to prevent the inner cylinder 7 from falling off from the outer cylinder 52 .

[0032] An opening is provided on the side wall of one side of the outer cylinder 52, and a second telescopic rod 61 is provided in the opening of the side wall of the outer cylinder 52. The second telescopic rod 61 is vertically slidably connected to the opening. Rotating blocks 62 are distributed and fixedly connected at both ends of the second telescopic rod 61. The rotating block 62 on one side is hinged to the top of the inner cylinder 7, and the rotating block 62 on the other side is hinged to the bottom of the second rack 6. The second rack 6 is mounted on a limiting frame 65, and the limiting frame 65 is mounted on the housing 2. The second rack 6 is vertically slidably connected to the limiting frame 65. A second gear 64 is provided on one side of the second rack 6 with a gear block, and a third rack 63 is provided on the other side of the second gear 64.

Under the transmission action of the rotating block 62 and the second telescopic rod 61, the inner tube 7 is controlled to move downward along the outer tube 52 so that the puncture needle 81 penetrates into the patient's pericardium.

[0034] A drainage tube 22 is provided below the third rack 63, and the drainage tube 22 is installed on the shell 2. The bottom of the drainage tube 22 is connected to the outside of the shell 2. A collecting tank 23 is installed below the drainage tube 22.

A piston 67 is vertically slidably connected in the drainage tube 22, and the top of the piston 67 is fixedly connected to the third rack 63 through a rod. A sealing gasket 68 is provided on the surface of the piston 67, and the piston 67 is sealingly and slidably connected to the drainage tube 22 through the sealing gasket 68.

[0035] During the upward movement of the third rack 63, the piston 67 is driven to move upward. The sealing gasket 68 enables the piston 67 and the drainage tube 22 to slide in a sealed manner. As the piston 67 slides upward, the internal pressure gradually decreases, so that the accumulated fluid in the pericardium is drawn out into the drainage tube 22 and flows into the collecting tank 23 for collection. The collected tank 23 can be removed to clean the drawn out accumulated fluid.

[0036] A fixed tube 8 is installed in the inner tube 7, and a connecting tube 82 is installed above the fixed tube 8. The connecting tube 82 is communicated with the inside of the fixed tube 8, and the other side of the connecting tube 82 passes through the inner tube 7. The other end of the connecting tube 82 is communicated with the drainage tube 22. A fixing ring 83 is fixedly connected above the fixed tube 8, and the connecting tube 82 passes through the middle of the fixing ring 83. The connecting tube 82 is configured as a hose.

[0037] Through the structure of the connecting tube 82 , after the puncture needle 81 penetrates the patient's pericardium, the accumulated fluid drawn out from the fixed tube 8 enters the collecting tank 23 along the connecting tube 82 for collection.

[0038] A clamp ring 84 is horizontally slidably connected inside the fixing ring 83, and the clamp ring 84 is clamped and connected to the connecting pipe 82.

A lifting mechanism 72 is installed above the lifting plate 71. The lifting mechanism 72 controls the lifting plate 71 to move up and down in the inner tube 7.

[0040] The lifting plate 71 is controlled to move upward or downward by the lifting mechanism 72. After the lifting plate 71 is lifted, the second connecting rope 86 is gradually tightened, and the second connecting rope 86 is pulled upward, so that the second connecting rope 86 drives the clamp ring 84 to open to both sides, and the connecting tube 82 is loosened, so that the patient's pericardial effusion can flow out through the connecting tube 82. After the lifting plate 71 descends, the second connecting rope 86 is loosened, and under the elastic force of the second spring 85 , the clamp ring 84 contracts inwardly to clamp the connecting pipe 82 , thereby blocking the flow in the connecting pipe 82 .
