AI Technical Summary
Existing endoscopes have inconsistent stone removal effects in urinary system treatments, resulting in poor stone fragmentation in certain areas and low efficiency in removing stone particles.
Design an instrument tube comprising a first channel and a second channel, which are radially arranged and connected by a connecting port for guiding instrument insertion and fluid medium delivery. The width of the connecting port is smaller than the radial width of the channel, enabling flexible extension of the instrument in different positions and synchronous delivery of fluid.
It improves the efficiency of stone removal in different locations, reduces fluid delivery resistance, increases the flow area of fluid delivery, and adapts to the treatment needs of different lesion locations.
