조향 가능한 세장형 의료 기구를 위한 제어 시스템의 백엔드 메커니즘이, 콤팩트하고 신뢰 가능한 조향 제어를 세장형 의료 기구에 제공하도록 배열된, 복수의 구동 구성요소 및 조향 구성요소를 포함한다. A control system for an elongate member actuated via a pull wire comprises a chassis fixable in place relative to the elongate member during use and a pulley carried by the chassis, the pulley having a first pull wire-supporting surface structurally configured to support the pull wire, the pulley being rotatable about a first axis. The system further comprises a wall carried by the chassis and a capstan carried by the chassis and rotatable about a second axis aligned at an orthogonal angle relative to the first axis, the capstan having a second pull wire-supporting surface that permits the pull wire to wrap around the capstan, wherein the wall extends circumferentially around the capstan and includes a slit through which the pull wire extends.
