[0016] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.
[0017] This utility model discloses a suction and aspiration device for hepatobiliary surgery, such as Figure 1-4 As shown, the aspiration device for hepatobiliary surgery mainly includes a support 1, an aspiration assembly 2, a fluid guiding assembly 3, and a fluid storage assembly 4. The aspiration assembly 2 and the fluid storage assembly 4 are detachably mounted on the support, and the aspiration assembly 2 and the fluid storage assembly 4 are connected through the fluid guiding assembly 3.
[0018] In this embodiment, a quadruped 11 is mounted on the base 1, and casters 12 are mounted on the quadruped 11, which allows for more convenient and stable movement during drainage compared to manual drainage. The bottle rack 13 on the upper part of the base 1 can hold the extraction bottle 25 and the storage bottle 41.
[0019] In this embodiment, the drainage assembly 2 is connected to the surgical site via the drainage suction head 26 at the end of the drainage tube 21, guiding the body fluid through the spherical probe 263 and filter screen 262 on the drainage suction head 26 to filter the body fluid. Specifically, the spherical probe 263 is connected to the drainage suction head 26 using a threaded connection, and the filter screen 262 prevents the drainage tube 21 from becoming clogged. After disassembling the spherical probe 263, the internal filter screen 262 can be cleaned. The spherical probe 263 has evenly distributed... The cloth has an absorption hole; the drainage tube 21 is equipped with a flow regulating valve 23 and a first-way valve 24, which can regulate the flow rate of aspirated body fluid to prevent excessive drainage speed from causing a decline in the patient's physical function. The first-way valve 24 can effectively prevent the backflow of liquid in the drainage tube and ensure the normal operation of the drainage work; the suction bottle 25 is equipped with a negative pressure fan 22. When the negative pressure fan 22 is started, a pressure difference is formed inside and outside the bottle, and the pressure inside the bottle is negative, so the body fluid enters the drainage tube.
[0020] In this embodiment, the flow guiding component 3 includes a flow guiding tube 31 and a second one-way valve 32. The flow guiding tube 31 is connected to the lower end of the drainage bottle 25 and the storage bottle 41, so that the body fluid in the drainage bottle 25 can flow smoothly into the storage bottle 41. The flow guiding tube 31 is also equipped with a second one-way valve 32 in the middle to prevent the body fluid from flowing back into the drainage bottle 25.
[0021] In this embodiment, the fluid storage assembly 4 includes a storage bottle 41, an alarm 42, and a level sensor 44. The level sensor 44 is installed at the upper end of the storage bottle 41 and is connected to the alarm 42 on the storage bottle 41 via a cable. The alarm will activate when the storage bottle is full of fluid, reminding staff to replace the storage bottle to prevent untimely replacement from hindering bile drainage and threatening the patient's life. The outlet 43 is for draining bile from the full storage bottle for reuse.
[0022] In this embodiment, when the present invention is working, the negative pressure fan 22 is activated to create a pressure difference between the inside and outside of the bottle. The pressure inside the bottle is negative, and the body fluid enters the drainage tube 21. The drainage suction head 26 on the drainage tube 21 filters the body fluid, and the body fluid flows into the extraction bottle 25. The liquid in the extraction bottle 25 flows into the storage bottle 41 through the guide tube 31. When the liquid in the storage bottle reaches a certain height, it will trigger the liquid level sensor 44, and the alarm 42 will sound an alarm, allowing us to replace the storage bottle in time.
[0023] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
