This invention describes a specialized tube, designed for use in endoscopic or laparoscopic surgery, that helps deliver a paste from a syringe. It features a clever valve system at one end that can first suck in air from the surroundings and then push that air through the tube. This allows the device to use a puff of air to either clear the tube or precisely push the paste out to its destination.
Why it matters: The increasing complexity and viscosity of surgical glues and sealants used in minimally invasive procedures may highlight the need for precise, gas-assisted delivery and tube clearing, making this solution more relevant today.
