Device and method for discharging a reactive liquid

A device for dispensing first and second liquids with a gas for use in a surgical procedure, comprising;

• an instrument having a cannula;
• and
• a low-pressure tip, comprising;
• a tip housing having a distal wall and a proximal portion, the tip housing at least partially defining a high pressure chamber therein and the distal wall having a first aperture in fluid communication with the high pressure chamber, the proximal portion being attached to the cannula;
• a first tube adapted to fluidly communicate the first liquid at a first pressure from the cannula to distally beyond the high pressure chamber through the first aperture;
• and
• a first gas flow channel adapted to fluidly communicate the gas from the cannula at a second pressure to the high pressure chamber for discharge from the first aperture, the second pressure being higher than the first pressure,
• wherein the first tube and the first aperture are adapted to dispense the first liquid and the gas for creating a low pressure zone distal of the first tube in order to dispense droplets of the first liquid,
• wherein the distal wall has a second aperture in fluid communication with high pressure chamber, and the low-pressure tip further comprises:
• a second tube adapted to fluidly communicate the second liquid at the first pressure from the cannula to distally beyond the high pressure chamber through the second aperture;
• and
• a second gas flow channel adapted to fluidly communicate the gas from the cannula at the second pressure to the high pressure chamber for discharge from the second aperture, the first and second gas flow channels having separate channel apertures at the high pressure chamber,
• wherein the second tube and the second aperture are adapted to dispense the second liquid and the gas for creating the low pressure zone distal of the second tube in order to dispense droplets of the second liquid, wherein the first and second tubes extend through the respective first and second apertures and past the distal wall, wherein the first and second tubes and the first and second apertures define respective first and second gas flow gaps, the first and second gas flow gaps being in fluid communication with the high pressure chamber for dispensing the gas therethrough.
