B 型超声引导下的诊断性穿刺或治疗是一种简单、可靠、有效的介入超声方法,常用的穿刺探头是—种专用探头,价格昂贵,以至很多单位不能应用此种先进诊疗方法。我们试制出一种导针测量尺,和普通探头配用起专用探头的作用,经体外试验和临床应用,效果良好。一、结构原理如图所示,假设 B 点为体内病灶,BC 是病灶到体表探头之距离,其值在冻结图象后用电子卡尺可直接测出,DC、AD 可在探头和测量尺上测出,由于 B-mode ultrasound-guided diagnostic puncture or treatment is a simple, reliable and effective interventional ultrasound method. The commonly used biopsy probe is a special type of probe which is expensive and can not be applied by many units. We try out a guide pin measuring ruler, and the special probe with the role of the ordinary probe, in vitro tests and clinical applications, the effect is good. First, the structural principle shown in Figure, assuming point B is the body lesions, BC is the distance from the lesion to the surface of the probe, the value of the electronic caliper can be measured directly after freezing the image, DC, AD in the probe and measuring ruler On the measured, due
