We have invented a distraction device that can be placed intraorally and provides autodistraction. The device consists of two units: an implantable component that is applied directly on the bone, and an external component that is distant from the surgical site. The external component is mounted on a standard, battery-driven portable syringe driver or infusion pump. A fine flexible non-compressible tube connects the two. The compression of the bellows in the external component causes fluid to be forced through the connecting tube into the distraction component. The combination of the sealed system and incompressible fluid guarantees expansion of the bellows of the distraction component and gradually separates the bone segments.
我们发明了一种可口腔内放置并能自动撑开的牵引装置。该装置由两个部分组成：一个可直接应用于骨骼的植入部件，以及一个远离手术部位的外部部件。外部部件安装在标准的、电池驱动的便携式注射器驱动器或输液泵上。一根纤细、柔韧且不可压缩的管子将两者相连。外部部件中波纹管的压缩会使液体通过连接管被压入牵引部件。密封系统和不可压缩液体的组合保证了牵引部件波纹管的膨胀，并逐渐分离骨段。
