A novel diathermy knife with suction function capable of keeping clear visibility while controlling bleeding

摘要

Forced Coag, effect 2, 80 W; Erbe Elektromedizin GmbH, Tuebingen, Germany). Four tiny ports at the tip of the sheath can both suck and inject liquid; to use suction, the assistant manually applies negative pressure to the distal end of the sheath using a syringe. This function maintains visibility at the operation site while sucking up bloody fluid, enabling the endoscopist to recognize the bleeding point and perform precise hemostasis (Figs. 1-6). Furthermore, in comparison with conventional needle-type knives, the ball-shaped tip is slightly thicker in diameter, possibly leading to a higher hemostatic ability against submucosal blood vessels.
