PIV MEASUREMENT OF FLUID FLOW INSIDE A HUMAN UTERUS MODEL FOR CRYOABLATION

摘要

A new technique has been proposed that allows cryoablation to be achieved on the entire inner surface of the endometrium by circulating very cold perfluorochemical (PFC) fluid inside the human uterus. To understand the PFC flow field inside the uterus during cryoablation, a uterus model was constructed; a fluid delivery system including the fluid delivery probe was designed and built to simulate the PFC flow during cryosurgery. With particle image velocimetry (PIV), the fluid flow inside the uterus was investigated at room temperature to display a 2-D whole field velocity contour and vector plot.
