泪道探通插管是治疗泪道阻塞较有效的方法之一。但是,传统的方法在技术操作中存在着较大的盲目性,容易造成假道,尤其是上下泪道同时阻塞的病例。我们用超声引导施行这一手术,弥补了传统方法的这一不足;现介绍如下。器械与方法我们用日本产ZK-2560型回声仪与ZL-2750型轻便式扫描器配套的眼用超声仪,换能器频率7.5兆赫,具有A、B型两种功能。泪道探通插管备有:泪点扩大器、泪道探针、塑料管(直径0.8mm,长6cm的空心管)、2ml注射器;钝头5号球后针头;及表面麻醉剂和局部浸润麻醉剂各一支。操作步骤及超声所见(封3图):①超声 Tears Road Probes intubation is the treatment of lacrimal duct obstruction more effective way. However, the traditional method has great blindness in the technical operation, which easily causes the false passage, especially the upper and lower lacrimal duct obstruction. We use ultrasound to guide the implementation of this operation, to make up for this lack of traditional methods; are described below. Instruments and methods We use the Japanese-made ZK-2560-type echo scanner and ZL-2750 Portable Scanner ophthalmic device, the transducer frequency of 7.5 MHz, with A, B-type two functions. Lacrimal duct probing intubation with: punctum magnifier, lacrimal probe, plastic tube (diameter 0.8mm, 6cm long hollow tube), 2ml syringe; blunt 5-ball rear needle; and surface anesthetic and local infiltration Anesthetic each one.
