在体外震波碎石过程中 ,准确的定位是碎石成功的一个重要环节。由于碎石机的震波焦点焦距是恒定的 ,而患者的体型又不统一 ,所以 ,这就要求我们操作人员除了利用碎石机床位高低和小 C臂来调节震波焦距以外 ,还要充分利用碎石机震波波源前的水囊充盈度来调节震波焦距 ,以达到定
In vitro shock wave lithotripsy, accurate positioning is an important part of the success of the gravel. Because the focal length of the shock wave of the lithotripsy machine is constant, and the body shape of the patient is not uniform, therefore, this requires our operator to use the lithotripter height and small C arm to adjust the seismic focal length, Stone shock wave source before the filling of the water sac to adjust the focal length of the shock, in order to achieve
