Academician Yazhu Chen is a pioneer and leader in the research and development of large-scale medical devices in our country. In the 1980s, she had already achieved fame in the field of high-voltage electrical technology. In order to enable domestic kidney stone patients to receive the most advanced minimally invasive treatment at an affordable price, she resolutely devoted herself to the field of biomedical engineering and engaged in extracorporeal lithotripsy research and development of equipment.
At that time, extracorporeal lithotripsy equipment was an emerging technology that intersects multiple disciplines such as electronics, computers, automation, imaging, and medicine. There is no precedent in China. Due to the country’s economic difficulties and limited funding for scientific research, such an interdisciplinary self-selected project cannot even be found by the counterpart funding application department. Despite this, Academician Chen still overcomes all difficulties and inspires to develop an extracorporeal lithotripsy device to protect patients with kidney stones from the pain of surgery.
There are many difficulties in cross between medical and engineering. Academician Chen and the team learned from the beginning and gradually overcome one after another. With insufficient funds, she ran around and finally received a 400,000 natural science fund low-interest loan with the support of the Shanghai Science and Technology Commission. At the end of 1985, the kidney stone in vitro pulverizer was successfully developed, and the price was only one-tenth of the imported equipment. As of today, the "kidney stone in vitro pulverizer" led by Academician Yazhu Chen has cured millions of patients in China.
