意为「髋部旋转器」（hip turn）。这是十八世纪的一种机械装置，用于实现外开（turn-out）。使用时双脚被固定于外开位，但该装置并不能在髋关节处将腿转开，而只能在踝关节与膝关节处实现外开。因此它未能达成其设计初衷。

“Hip turn.” This was a mechanical device of the eighteenth century designed for achieving a turn-out. The feet were fixed in a turned-out position in this device which did not turn out the leg at the hip joints but only at the ankles and knee joints. Therefore it did not fulfill the purpose for which it was designed.
