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

BACKGROUND: 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. MATERIALS AND METHODS: 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. RESULTS: 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. CONCLUSIONS: This simple and easy device facilitated the prevention of irregular adsorption of fatty tissue while using an irrigation-suction instrument for laparoscopic surgery.
