近年来,BD8828型体外震波碎石机在国内应用已较多见,患者亦渐增多。但观察其Ⅱ号探头的作用时发现有时出现“B”超结石图象不清或结石光团不在第二焦点上;而复位后结石光团却仍与第一焦点重合的现象。在这种情况下失去Ⅱ号探头的价值,从而影响了碎石的准确性。该震波碎石机属新技术应用,故对此问题大家一直较为注意。作者在多次使用中找出了该问题产生的原因及解决办法如下,供同道参考:
In recent years, BD8828 extracorporeal shock wave lithotripter has been more common in the country, patients are also increasing. However, when observing the role of probe II, it was found that sometimes “B” supercalculiar image was not clear or the light of the calculus was not located on the second focus; while the light of the calculus was still coincided with the first focus after the resetting. In this case, the value of Ⅱ probe lost, thus affecting the accuracy of gravel. The shock wave lithotripsy machine is a new technology application, so we have been paying more attention to this issue. The author finds out in many times the reasons for the problem and solutions as follows, for fellow reference:
