Background

In minimally invasive and open surgery, a suction irrigator is required to clean the abdominal cavity, and blood stains and small scraps in the abdominal cavity are extracted, and in orthopedic surgery, a suction irrigator is required to extract broken bones in orthopedics. Because of the small and few access channels into the human body during minimally invasive surgery, cables for monitors and surgical instruments are used. The existing aspiration irrigators have multiple lines, no distinction is made between aspiration and infusion channels in the extension tubing, and both irrigation and infusion and aspiration are common or dual channels during surgery, with blood and cellular tissue adhering to the channels during aspiration, causing the blood tissue to be re-mixed into the irrigation fluid and carried back into the body cavity.
