根据鼻泪管的生理解剖结构和病理特点,自1985年设计器械,于临床实施鼻泪管疏通术治疗慢性泪囊炎的鼻泪管阻塞,取得了满意的疗效,报告临床研究治疗观察情况如下: 一、器械设计:研制的BDZ型电动环钻器主要数据:①钻头:长10mm,截面φ3.0mm空心,内φ2.6mm。②钻柄:长30mm,呈17～20°弧弯形。③电机:工作电压12V,电流0.6A,转速为50次/秒。④植入义管:有聚甲基丙烯酸甲脂(即PMMA)和医用硅胶管二种。二、手术方法:基本的麻醉和手术步骤同常规泪囊手术方法,主要在于:暴露泪囊之后、将泪囊
According to the physiological anatomy and pathological features of nasolacrimal duct, we designed instruments to treat nasolacrimal duct obstruction of chronic dacryocystitis in the clinical implementation of nasolacrimal duct dredging, and achieved satisfactory results. Clinical observation and treatment are reported as follows : First, the instrument design: developed BDZ-type electric torch main data: ① drill: length 10mm, section φ3.0mm hollow, φ2.6mm inside. ② drill handle: length 30mm, was 17 ~ 20 ° arc-shaped. ③ motor: working voltage 12V, current 0.6A, speed 50 times / sec. Implantation of justice: polymethyl methacrylate (PMMA) and medical silicone tube two. Second, surgical methods: basic anesthesia and surgical procedures with conventional lacrimal sac surgery, mainly lies in: After exposure to the lacrimal sac, the lacrimal sac
