Design of Congenital Anal Atresia Recanalization Anastomosis DeviceBased on Magnetic Compression Technology

目的设计基于磁压榨技术的肛门闭锁再通吻合装置。方法分析先天性肛门闭锁疾病的特点,结合磁压榨技术的原理,设计微创下磁压榨肛门闭锁再通吻合装置。结果通过特殊形状设计的磁压榨吻合装置,借助穿刺技术在肛穴中心部位与直肠盲端建立穿刺道,纺锤状子磁体沿穿刺针置入直肠盲端,将与子磁体配套的带沉孔的圆柱状母磁体置于肛穴部位,子母磁体相吸并压榨可实现肛门闭锁的重建再通。结论该设计基于磁压榨吻合原理,设计巧妙、操作简便、创伤小、安全性高,具有很大的临床应用价值。

Objective To design a device for treating congenital anal atresia based on magnetic compression technology. Methods Firstly, the characteristics of congenital anorectal atresia were analyzed. Then, a minimally invasive magnetic compression device for anorectal atresia recanalization was designed by combining with the principle of magnetic compression techniques. Results A puncture path was established between the anal point and the blind end of the rectum by designing a special shape of magnetic compression anastomosis device. The spindle magnet was placed in the blind end of the rectum. The cylindrical parent magnet with sink hole matched with the daughter magnet was placed in the anal cavity. The parent magnet was sucked and compressed to achieve the anastomosis of anal atresia. Conclusion The design is performed based on the principle of magnetic compression anastomosis. It has the advantages of ingenious design, simple operation, small trauma and high safety. It has great clinical value.
