At that time, extracorporeal lithotripsy was an emerging technology of interdisciplinary integration of electronics, computer, automatic control, imaging, medicine and other disciplines. Lack of relevant precedents and scientific research funds posed great obstacles to the research. Despite the dilemmas, Academician Chen was still full of ambition to develop an extracorporeal lithotripsy device to save patients with kidney stones from the pain of surgery.
Facing great barriers in medical-engineering Interdisciplinary technology, Academician Chen and her team started from scratch and tried every effort to overcome the difficulties. To solve the financial matter, she went around and got 400,000 low-interest loans from the Natural Science Foundation with the support of the Shanghai Science and Technology Commission. By the end of 1985, she successfully built the extracorporeal lithotripter, the price of which was one tenth of imported equipments.
