The content on this page is intended to healthcare professionals and equivalents.
With thinner sheath, the space between the instrument channel and FlushKnife is enlarged. It enables increased suction performance while stabilizing the sheath.
By adopting thinner sheath and more flexible material, slim type FlushKnife is capable of bending more acutely.
Resistance during scope insertions is reduced by enhanced flexibility and thinner sheath. Less kinking is likely to reduce stress on physicians.
Even with thinner sheath, water jet function is same as conventional type, and the knife maintains its sharpness throughout the procedure.
Tip design to enhance ESD efficiency
