Advances in Laparoscopic surgeries and CFD perspective of suction-irrigation devices

The need for suction-irrigation devices in almost every surgery i.e., from an open incision to Laparoscopic, is well recognized by all different kinds of surgeons. This paper significantly highlights several problems of pneumoperitoneum, blocking, and other inefficiencies like misplacement of sponges, etc., while using suction and irrigation devices during surgeries. An irrigation device is studied for cleaning wounds or blood inside a human body. The citation has been counted as one of the most imperative factors in comprehending the quality of Laparoscopic instruments and their use during surgery. It helps to solve inefficiencies caused by separate suction and irrigation systems in surgeries such as suctioning the wound while irrigating and then simultaneously cauterizing to seal the tissue. Computational Fluid Dynamics or CFD evaluation is one of the key analysis strategies used to forecast fluid flow, heat transfer, and chemical reactions occurring among various materials which consists of fluid. Computational analysis is performed in the present study using ANSYS FLUENT as a commercial package. After evaluation of the modeled layout, the acquired outcomes for pressure, mass flow rate, and velocity at the inlet and outlet of the tube are cautiously studied, and essential optimizations are made in the design to prevent any undesired outcomes. The pressure drop in the instrument and the pipe is determined, and flow rates are compared subsequently. The objective of this paper is to determine the mass flow rate across an instrument for different pressures and to suggest improvements in the Suction- Irrigation device by enhancing additional features to make it as multi-functional instrument that can be used for minimally invasive surgeries.
