How to Prevent Irregular Adsorption of Fatty Tissue into the Irrigation-Suction Instrument

Background: While using an irrigation-suction instrument for laparoscopic surgery, the irregular adsorption of fatty tissue may damage the tissue or obstruct continuous sucking. New devices of divided silicone drain tip and Count-on Q™ to prevent irregular adsorption of fatty tissue were reported. Materials and methods: A cigarette-type silicone drain was cut 4 cm in length, slipped over the instrument to cover the side holes, leaving 1.2 cm free from the end and fixed by means of 1-0 silk above the side holes. The free tip was divided vertically into four even pieces like octopus arms. Count-on Q™ was the irrigation-suction instrument equipped with multiple small side holes. Results: Divided silicon drain tip could prevent the irregular adsorption of fatty tissue (greater and lesser omentum or epiploic appendices) and could suck saline, fresh, and coagulated blood continuously. Count-on Q™ also could prevent the irregular adsorption of fatty tissue and could suck saline and fresh blood except coagulated blood continuously
