Increased suction capability

With thinner sheath, the space between the instrument channel and FlushKnife is enlarged. It enables increased suction performance while stabilizing the sheath. 

Smaller bending radius

By adopting thinner sheath and more flexible material, slim type FlushKnife is capable of bending more acutely.

Smoother scope insertion

Resistance during scope insertions is reduced by enhanced flexibility and thinner sheath. Less kinking is likely to reduce stress on physicians.

Effective water jet function

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

FlushKnife BT-S has a ball tip, which produces good traction, enabling the target tissue to be dissected smoothly. The ball tip touches wider range of tissue and supports effective coagulation.

FlushKnife N-S has a slim needle-shaped tip. 
It provides stronger dissection capability by high current density and enables sharp marking.

2000mm and 2300mm working length

Two types of working length allow combination with a variety of endoscopes. It supports ample distance between physician and assistant. 

Easier identification
