Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a controllable flow irrigation aspirator. BACKGROUND

[0002] In laparoscopic surgery, in order to clean the surgical field, it is often necessary to use sterile water or specific liquid to flush the wound, and at the same time, it is also necessary to use a negative pressure catheter to aspirate and remove sewage and blood and other pollutants from the wound and surgical field. The aspirator is a device for removing blood, exudates, pus, and other substances in the thoracic cavity during surgery. The use of the aspirator can make the surgery clear and reduce the chance of contamination. The principle of the aspirator is very simple, that is, by a certain method to create a negative pressure state of the suction head, so that the atmospheric pressure will squeeze the material outside the suction head to the suction head, thereby completing the "suction" effect.

[0003] The currently used irrigation aspirator connects the water source for irrigation at the irrigation end, and connects the negative pressure for suction at the suction end. The water source and negative pressure cannot be adjusted at will, and only by closing the irrigation water source and closing the negative pressure power supply through the cut-off clamp can the negative pressure be closed. However, for different situations of the tissue during surgery, the best irrigation and negative pressure required are not the same, thus bringing difficulties to the irrigation and aspiration process and failing to meet people's needs.

[0004] Therefore, we propose a controllable flow irrigation aspirator. SUMMARY
