中文摘要 | 本研究旨在設計一個新型電水式碎石機之震波產生器,此震波產生器包括了一個反射凹杯及一組正、負極火星塞。新型震波產生器的性能評估是在設定不同擊發電壓下進行,並與寶健(LiteMed)公司的之震波產生器做性能比較。震波產生器性能評估是依據每擊發五百下震波之聚焦壓力的平均值和每次能量釋放的均一性,作為性能評估的基準。本文建議新的震波產生器最好選擇電壓為6-8 kV下操作。實驗證實新的震波產生器確實能夠產生平均的最大聚焦壓力和具有每次能量釋放的均一性,比寶健公司的震波產生器有更佳的性能。 |
英文摘要 | A new-type shock wave generator is designed for an electrohydraulic lithotriptor. The generator consists of a reflector and two electrodes. The performance of the new generator is evaluated at different voltage settings, and is compared with that for the old-type generator from the LiteMed Inc. The generator performance is measured based on the average of the peak pressures for every 500 shocks. The in vitro study suggests a better voltage setting of 6-8 kV for the new-type generator, since the new-type generator can produce higher peak pressures and more consistent-energy shocks at lower voltage than the old-type generator does. |
