A novel laparoscopic suction device for applying precise aspiration during laparoscopic surgery: sponge-tip suction tube.

Abstract Aspiration of the intra-abdominal fluid and debris is usually needed during different stages of the operation. This is necessary to protect the intra-abdominal space from contamination and/or to remove blood or tissue fluids occurring during the operation. It is also essential for obtaining a clean surgical area. Aspiration of the intra-abdominal fluid is relatively more difficult in laparoscopic surgery because of the suctioning of the omentum and intestine with the aspirator. In this paper, we report on a new suction device (sponge tip suction tube; STST), which allows the surgeon easier suctioning of intra-abdominal fluid. STST has an additional sponge tip and air channel, which prevents the device from suctioning intra-abdominal organs, such as the intestine and omentum. We tested the efficacy of STST in a simulated intra-abdominal space, such as a large transparent plastic bag with fresh sheep intestine-omentum and with 2000 cc of physiologic saline solution and 14 mm Hg of air pressure.
