Controlled continuous flow (CCF) is a new balanced pumping system which has been designed for the resectoscope. The system is controlled by an intravesical pressure sensor. Upper limits of pressure are set, and the input flow is shut off electronically if it is attained. Flow rates of up to 1,000 ml/minute can be achieved for maximum clarity of vision. Two hundred cases have been performed with the CCF resectoscope. Various parameters were measured and are presented. The results indicate that TURP can be performed safely and more efficiently with the CCF resectoscope.
可控连续流（CCF）是一种专为电切镜设计的新型平衡灌注系统。该系统由膀胱内压力传感器控制。设定压力上限，当达到该上限时，输入流会通过电子方式关闭。为了获得最大的视野清晰度，可实现高达每分钟1000毫升的流速。已经使用CCF电切镜进行了200例手术。测量并展示了各种参数。结果表明，使用CCF电切镜进行经尿道前列腺切除术（TURP）可以更安全、高效地进行。
