[0002] Thoracic surgical puncture drainage devices are medical instruments used for chest puncture and drainage. They typically consist of a puncture needle, drainage tube, and suction device, and are designed to safely and effectively remove pleural effusion or gas. The puncture needle enters the pleural cavity, and the suction device generates negative pressure to draw the effusion or gas out of the body, achieving therapeutic or diagnostic purposes. Some devices also have drug injection capabilities to meet different medical needs.
[0003] Most commercially available puncture drainage devices are secured using simple locking mechanisms, resulting in poor stability during use. Therefore, thoracic surgical puncture drainage devices are needed. Utility Model Content

[0024] The first hand crank 9 forms a rotating structure with the support base plate 1 through the first bearing 8, and the first hand crank 9 forms a fixed structure with the first threaded post 10 and the first connecting post 11. The first threaded post 10 forms a threaded connection with the first threaded plate 12, and the first threaded plate 12 forms a sliding structure with the first slider 13 and the first slide rail 14. When the first hand crank 9 is rotated by external force, the first threaded post 10 can be rotated. Through the threaded connection between the first threaded post 10 and the first threaded plate 12, the rotation of the first threaded post 10 can move the first threaded plate 12.
[0025] The first threaded plate 12 forms a rotating structure with the movable plate 16 via the first rotating shaft 15, and the movable plate 16 forms a rotating structure with the clamping plate 18 via the second rotating shaft 17.

[0026] Example 2
[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, this embodiment further illustrates Example 1. A hollow plate 19 is fixed to the side wall of the support frame 3. A second bearing 20 is provided at the top of the hollow plate 19. A second hand crank 21 is provided on the inner side of the second bearing 20. A second threaded post 22 is fixed to one end of the second hand crank 21. A second threaded plate 23 is threadedly connected to the outer periphery of the second threaded post 22.

This allows the puncture drainage device to be used at multiple angles and to remain fixed during use.
[0030] Working principle: First, the operator needs to rotate the first handle 9 by external force, which drives the first threaded column 10 to rotate. The rotation of the first threaded column 10 causes the first threaded plate 12 to move. The movement of the first threaded plate 12 causes the movable plate 16 to move. The movement of the movable plate 16 causes the clamping plate 18 to move. The relative movement of the two sets of clamping plates 18 can form a clamping assembly, which can easily clamp and fix the device for long-term stable support of the puncture drainage device. Then, by rotating the second handle 21 by external force, the second threaded column 22 can be rotated. The rotation of the second threaded column 22 causes the second threaded plate 23 to move. The movement of the second threaded plate 23 causes the movable slide rail 28 to move. The movement of the movable slide rail 28 causes the rotating slider 29 to rotate, which indirectly drives the second connecting column 30 and the supporting hollow ring 4 to rotate. Thus, the puncture drainage device can be used at multiple angles and remains fixed during use.
