A low-pressure tip for dispensing first and second liquids with a gas from a cannula for use in a surgical procedure, comprising; a tip housing having a distal wall and a proximal portion, the tip housing 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 adapted for attachment 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 the high pressure chamber, the low-pressure tip further comprising: a second tube adapted to fluidly communicate a second liquid at the first pressure from the cannula to distally beyond the high pressure chamber through the second aperture; wherein the second tube and the second aperture are adapted to dispense the second liquid and the gas for creating a low pressure zone distal of the second tube in order to dispense droplets of the second liquid, characterized in that the low-pressure tip further comprises: a second gas flow channel, isolated from the first 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, wherein the first and second tubes, and the first and second apertures, define respective first and second flow gaps,, the first and second flow gaps, being in fluid communication with the high pressure chamber for dispensing the gas therethrough, wherein the first flow gap surrounds the first tube for discharging gas generally circumferentially around the first tube, and the second flow gap surrounds the second tube for discharging gas generally circumferentially around the second tube, wherein the distal wall includes a plurality of nodes extending at least partially into the first and second flow gaps, for preventing the first and second tubes, from moving respectively within the first and second apertures, and maintaining the circumferential first and second flow gaps,. a second tube adapted to fluidly communicate a second liquid at the first pressure from the cannula to distally beyond the high pressure chamber through the second aperture; wherein the second tube and the second aperture are adapted to dispense the second liquid and the gas for creating a low pressure zone distal of the second tube in order to dispense droplets of the second liquid, a second gas flow channel, isolated from the first 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, wherein the first and second tubes, and the first and second apertures, define respective first and second flow gaps,, the first and second flow gaps, being in fluid communication with the high pressure chamber for dispensing the gas therethrough, wherein the first flow gap surrounds the first tube for discharging gas generally circumferentially around the first tube, and the second flow gap surrounds the second tube for discharging gas generally circumferentially around the second tube, wherein the distal wall includes a plurality of nodes extending at least partially into the first and second flow gaps, for preventing the first and second tubes, from moving respectively within the first and second apertures, and maintaining the circumferential first and second flow gaps,.
