我院自1991年1月至1992年10月,应用自制撕裂式导管鞘,成功地为15例患者安装了永久起搏器。15例患者均为住院病人,男8例,女7例,年龄29～79岁。房室传导阻滞9例,病窦综合征6例。起搏器均为VVI型,其中秦明公司7台,CPI公司、Medtronic公司各4台。材料及制作方法取长15 cm、内径约3 mm(与9F扩张管配套),壁薄及有一定硬度的塑料吸管1条,内径逐渐由大变小的扩张管接头一个,9F扩张管1条。用锐刀片切齐吸管一端,套入9F扩张管,将其一并插入另一扩张管接头,固定吸管及9F扩张管,按顺时针方向旋转1～2周,使管口变薄收紧和 Our hospital from January 1991 to October 1992, the application of self-made tearing catheter sheath, 15 patients successfully installed a permanent pacemaker. All 15 patients were hospitalized patients, 8 males and 7 females, aged 29 to 79 years. Atrioventricular block in 9 cases, 6 cases of sick sinus syndrome. Pacemakers are VVI type, of which Qin Ming 7, CPI, Medtronic company of 4. Materials and methods of production Take a length of 15 cm, an inner diameter of about 3 mm (with 9F expansion tube supporting), a thin wall and a certain degree of hardness of the plastic pipette, an inner diameter gradually smaller pipe expansion joints, 9F expansion tube 1 . With a sharp blade cut the end of the straw, set into the 9F expansion tube, it will be inserted into another expansion joint, fixed pipette and 9F expansion tube, clockwise rotation of 1 to 2 weeks, so that the nozzle thinning and tightening
