Interview With The Expert

What are the advantages of TriangleTipKnife?
First, it does not need any kind of axis alignment. It can hook effectively in any direction.

Also, by discharging spray coagulation, the submucosal layer will be dissected without any contact of the knife.

Are there any weak points of TriangleTipKnife?
When there is serious fibrosis in submucosal dissection,

it is better to use a hook because it has a thinner distal end than TriangleTipKnife.

Under what conditions do you use other devices as well?
If the dissected part of the mucosa starts dangling when you are about to resect,

it’s easier to complete the procedure using ITknife.
