In order to obtain the purpose of directional incision,the different incisional velocity and distance should be gained by means of changing elastic stress arca to cause pressure difference between the sides of anal canal and fistula.

使挂线按照手术者设定的方向缓慢切割、引流，即通过改变肛管与瘘管两侧橡皮筋的压力面积来产生压强差，导致不同的切割速度和距离以达到定向切割目的；并将效果与传统挂线做比较。

The whole brain of the subject was axially and coronally scanned in the normal stereotactic space with a slice 1mm thick by MR system. The caudate nucleus were identified, segmented, extracted, saved and three-dimensionally reconstructed on MRI by software system developed by Research Center of Biology, Harbin University of Technology.
