为避免负压吸宫术中负压所致并发症,我们采用自制族动流产器中止早孕84例,成功率达82.1％。现介绍如下。 1.旋动流产器的构造和功能:旋动器由旋环、导管、手柄组成(见附图)、旋环为由直径0.95mm不锈纲丝以3～4mm螺距螺旋卷曲而成的椭圆形闭合钢丝环,长轴15mm,短轴12mm。导管为长240mm、外径4.5mm、内径1.2mm的不锈钢管,近旋环端呈约140°弯曲。手柄为握持部分,金属外壳,内固定电机、变速元件、开关。导丝为直径0.95mm不锈钢丝,其穿行于导管内,两端分别连接旋环和电机。电机为直流6V 5W,转速由变速元件控制,由操作者藉调速开关钮在0～17r/s内调动。旋环、
In order to avoid the negative pressure caused by vacuum suction aspiration complications, we use homemade mobile abortion 84 patients with early termination of pregnancy, the success rate of 82.1%. Now introduced as follows. 1. Rotary abortion structure and function of the device: Rotor by the rotation ring, catheter, handle composition (see photo), the rotation of the ring by the diameter of 0.95mm stainless wire with 3 ~ 4mm pitch helical curled oval Shaped closed wire loop, long axis 15mm, short axis 12mm. The catheter is a stainless steel tube with a length of 240 mm, an outer diameter of 4.5 mm and an inner diameter of 1.2 mm, and is bent about 140 ° near the end of the convoluted ring. Handle for the grip part, metal shell, internal fixed motor, variable speed components, switches. Guide wire diameter 0.95mm stainless steel wire, which runs through the catheter, both ends are connected to the rotary ring and the motor. Motor DC 6V 5W, speed control by the variable speed components, by the operator to borrow speed switch button in the 0 ~ 17r / s transfer. Rotary ring,
