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

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. Whereas the suctioning of all the fluid was difficult and time consuming when the conventional suction unit was used, all of the saline solution was easily and quickly suctioned when STST was used. In conclusion, STST provides a safe, fast, and complete fluid extraction.
