Hardware is very critical, shock wave generator is the key to determine the energy and stone crushing time, and even precision at any time, pure copper material is the best, high hardness, strong energy, stone crushing time is short, crushed clean, only Shanghai Jiaotong University stone crushing and Germany Dornier in use, the two a college out of the focus on technology, one is a German enterprise meticulous, other companies in order to save costs are replaced by stainless steel, or other materials. Or other materials, after three months, the cylinder will appear serious wear and tear, the focus of reflection began to become larger, the effect of gravel serious attenuation.
According to Shanghai from the first hospital to the tenth hospital Huashan Hospital Zhongshan Hospital Ruijin Hospital East China Hospital and so on dozens of big three even internationally renowned hospitals purchasing situation, are Shanghai Jiaotong University and the German Dornier machine, I was in the East China Hospital internship out of the hospital, and then work in Zhongshan Hospital, and later transferred to the Ruijin, experience tells me that the Dornier equipment is the best, but the price is too expensive. Shanghai Jiaoda (now belongs to the Kam Medical, is a listed company) equipment is more solid, durable, our hospital *** bought three, the earliest one is the director of the Liu hand to buy, has been 15 years ah, can still be used, indeed more stable, Jiaoda people, not too smooth, the school's traditional thinking, the equipment and hardware are first-class, supporting the X-ray machine are their own R & D and production, relative to other domestic lithotriptic machine The company, more perfect, put aside the ability of the salesman, just talk about the equipment, I think, Jiaoda's lithotripter is the best, more suitable for the use of Chinese hospitals and choice.
By the way, I would like to remind you that Jiaoda's salesman is more honest, their electrodes can be used to do three patients, while other companies' electrodes can only be used to do one patient, or even to do one patient needs 2-3 electrodes,, but the price of electrodes is almost the same, so in the promotion, Jiaoda's salesman is more generous. Just one electrode are so, you think about how much difference inside...? The high voltage generator used by Jiaoda is even the Italian IMD, the price is super expensive, and I contacted other lithotripter enterprises, are domestic, even more abominable is still using industrial frequency X-ray machine,, the radiation dose is too big a la ，，，， So I can only say: some are businessmen, can sell the poor product into a high price, and some are academics, the good thing lack of publicity,, or simply do not want to sell more money.
The real experience, please judge for yourself.
