A New Device to Prevent Irregular Adsorption of Fatty Tissue While Using an Irrigation-suction Instrument for Laparoscopic Surgery: Divided Silicone Drain Tip.

While using an irrigation-suction instrument for laparoscopic surgery, irregular adsorption of fatty tissue may damage the tissue or obstruct continuous sucking. A new device made up of a divided silicone drain tip to prevent irregular adsorption was reported.A cigarette-type silicone drain was cut 4 cm in length. It was slipped over the instrument to cover the side holes, leaving 1.0 to 1.5 cm free from the end of the instrument. It was fixed by means of 1-0 silk above the side holes. Finally, the free tip was divided vertically into 4 even pieces like octopus arms.This device could prevent the irregular adsorption of fatty tissue (greater and lesser omentum, or epiploic appendices) and could suck saline, fresh, and coagulated blood almost continuously.This simple and easy device facilitated the prevention of irregular adsorption of fatty tissue while using an irrigation-suction instrument for laparoscopic surgery.
