It is often accepted and used.

In laparoscopic surgery, there is a suction & irrigation tube among the equipment used to remove blood or contaminated water and wash the abdominal cavity with physiological saline.

There are reusable equipment that is used several times after disinfection, but recently, it has been developed and released as a product, so disposable products are preferred and used in many hospitals to prevent the inconvenience of disinfection and infection.

In conventional products, since the washing and suction passages are the same, during the suction process, some of the internal organs such as the intestine, mesentery, and omentum in the patient's abdominal cavity are often sucked into the suction passage, causing problems in the suction process and the suction passage. If the internal organs caught in the viscera are towed using surgical instruments, the tissue may be damaged or bleed, resulting in unnecessary additional surgical manipulation.

Accordingly, there is a demand for the development of a suction irrigation tube that reduces the phenomenon that the internal organs of the patient are caught in the small suction port during suction.

Here, when washing the surgical site, not only the washing water channel 21 but also the contaminated water channel 25 of the suction tube 20 may be supplied at the same time to wash the surgical site.

Then, a negative pressure is applied to the surgical site through the suction tube 20 . At this time, a negative pressure may be applied to the suction tube 20 while supplying the washing water to the surgical site. Here, in a state in which the cauterization tip 60 protrudes from the tip 20a of the suction tube 20, negative pressure may be applied to the surgical site.

As negative pressure acts on the surgical site, the entire amount of contaminated water generated in the surgical site is sucked into the contaminated water channel 25 of the suction tube 20 and discharged to the outside through the inlet and outlet 31 .

At this time, the suction force due to the negative pressure applied to the surgical site is not transmitted to the washing water supply hole 15 of the insertion tube 10 by the one-way valve 43 of the valve receptor 41 provided on the washing water channel 21. No, the contaminated water is sucked only through the contaminated water channel 25 of the suction pipe 20 .

Accordingly, when the contaminated water generated in the surgical site is sucked or negative pressure is applied to the surgical site, the organs of the surgical site are prevented from being sucked into the washing water supply hole 15 of the insertion tube 10 .

As described above, in the multi-channel suction washing tube according to an embodiment of the present invention, when the contaminated water generated at the surgical site is sucked, the washing water supply hole is inserted so that the tip of the suction tube is located between the tip of the insertion tube and the washing water supply hole.
