1. Outline
This resinoid model respresent almost similar figure of human stomach, and can be used
for the training of ESD. Considering the operability of endoscope, the transition part,
from esophagus to stomach is made of soft resin. By setting a real dissected stomach
of porcine at the area where ESD is supposed to be executed, very similar feeling of
human stomach wall can be recognized using endoscope.
2. Characteristics
(1) The training can be started simply with the combination of this resinoid model and
dissected porcine stomach.
(2) Very realistic and similar feeling to the actual treatment.
(3) Perforatoin procedure which never be performed during the actual treatment can be
experienced while recognizing the risk of treatment with realistic feeling.

Electrode used for ESD Training Model
One (1) pc of exclusive electrode for ESD Training Model (applicable for electrode code
with clip (P code)) is attached with the model but this electrode is not sold separately.
Please use the electrode currently used at your site by processing for ESD Training
Model. However reusable type electrode cannot be used since it does not fit with the
opening shape of training model. Please use disposable type without fail.
Processing Example
①Mono-polar type without code(Ex.: 1149 manufactured by 3M）
②Mono-polar type with code （Ex.: 1149C manufactured by 3M, CONMED made, etc.）
＊ ③Partible type without code
（Ex： NESSYΩ manufactured by ERBE、MAJ-897 manufactured by Olympus, etc.）
*Basically “Partible type” is not recommendable since the electricity may not be turn on stably.
(There will be some possibility of error sound). It is desirable to use “mono-polar type” but if you need to
use “Partible type”, it may be used by holding gauze soaked with saline solution between porcine slice and an
electrode.
