Interview With The Expert
It hooks the mucosa for incision and dissection, so it is less invasive for the deeper tissues. The rotary function provides the ability to align the knife horizontally or vertically. Marking with the back of the HookKnife™ device may reduce the risk of perforation. In addition, use of the distal end cover isolates the high-frequency current. The ability to perform dissection by directly observing the submucosal layer enables pre-coagulation. It is nice to be able to perform dissection with a good view and no bleeding.
The needle knife is convenient because its cutting style is like flicking the tissue. Also, the ITknife™ and FlexKnife™ devices have a higher vertical incision speed, so I sometimes use them instead of the HookKnife™ device.
