Electrosurgical knife with the water-jet function of tip-type during endoscopic treatment injection.

ABSTRACT:

Objectives

This study aimed to objectively evaluate the water-jet-functioned electrosurgical knife injection performances in a desktop experiment.

Methods

Five types of water-jet-functioned electrosurgical knives, including two injection styles of sheath-type (A: DualKnife J, KD-655L; B: FlushKnife, DK2620-J-B20S; C: Splash M-Knife, DN-D2718B; D: ISSEN, SN1650-20) and tip-type (E: ORISE ProKnife, M00519361) were evaluated. These knives were compared with an injection needle (Control: SuperGrip 25G) as a control. The injection speed under constant pressure and the injection efficiency for each knife against prepared porcine stomach mucosa were evaluated. The additional clear gel injections using an injection needle were observed using an indigo blue-colored gel to evaluate th
