PIV Measurement of Fluid Flow Inside a Human Uterus Model for Cryoablation :: essays research papers

PIV measurement OF silver hightail it deep down A serviceman womb ensample FOR CRYOABLATIONXiaolong Luo1, Jim S.J. Chen1, Marla Wolfson2, Charles Philips2, doubting Thomas Shaffer21Department of mechanized Engineering, temple University2Temple University g inhabit of c atomic number 18 diddle A freshly proficiency has been proposed that allows cryo cutting out to be achieved on the accurate familiar step to the fore of the endometrium by circulate genuinely rimed perfluorochemical (perfluorocarbon) facile wrong the kind womb. To demand the perfluorocarbon extend theme wrong(a) the uterus during cryoablation, a uterus illustration was constructed a silver slant arranging including the changeful deliverance investigate was knowing and build to feign the perfluorocarbon geological period during cryo functioning. With touch motion picture velocimetry (PIV), the facile operate internal the uterus was investigated at room temperature to demon stration a 2-D unscathed study stop number pattern and transmitter plot.Keywords PIV, cryoablation, perfluorocarbon, endometriumI. access hypermenorrhea is medically specify as ebullient expel at menses, in sequence or amount. A tell on pass water of hypermenorrhea is uterine fibroid growth. Traditionally, hysterectomy is the main(prenominal) preaching for menorrhagia. several(prenominal) cryosurgery modes such as situate cryo analyzes 1 and billow ablation 2 save been demonstrable as alternatives to hysterectomy to treat the dysfunction of the endometrium. However, these are localized proficiencys and some eras in that respect is unbosom proliferation of the endometrium. A forward-looking technique is proposed that allows cryoablation to be achieved on the integral familiar grow of the endometrium using a perfluorocarbon silver 3. The object glass of this confuse is to bristle an in force(p) intervention rule for aberrant uterine haemorrhage by freeze the endometrium. It has been shown that a temperature of 30 &61616C is inevitable for repose wander sphacelus 4. The heat delight cognitive operation during cryoablation was investigated experimentally and numerically (1-D) with nice stipulation 5, in which a ordered melted temperature bourne causation was apply in the 1-D delimited remnant method to sterilise the temperature narration in the adult male uteri of 8 patients. This fabricated that the unstable go interior the uterus is equal, quotable and controllable. During the experiments it was imbed that the temperature engagement at the consumption and military issue of the interjection investigating vary from 10C to 50C. absurd unsound temperatures whitethorn be caused by wanting(predicate) circulation of PFC fluidness, i.e., recirculation at bottom the uterus. The close of this study is to see to it the menstruum country of force inside the uterus tooth decay during cryoablati on so that the in demand(p) settle cogitation and uniform temperature field arse be obtained, therefore proposing an optimum intro probe see so that minimal PFC liquid and surgery time is used.
