needed 必要时回撤或重新放置•Avoid undue force 避免过度用力•Avoid excessive rotation 避免过度旋转•Do not lose your wire position…however 确保导丝处于正确位置•If wire position is lost, use caution when recrossing a dilated lesion and confirm luminal position 如果导丝偏离了正确位置，在重新放置导丝通过已扩张病变时应小心操作，并确认导丝始终位于血管真腔内Guide Wire Manipulation Guidelines操作导丝的指导方针Steering and tactile feedback 操控性和触觉反馈•Typical steering techniques include small alternating rotations from left to right, or larger clockwise rotations操控手法包括左、右方向来回轻微旋转，或顺时 针转动•Free wire tip motion is important to avoid catching plaque or dissection 头端保持活动自如，意味着导丝没有碰到斑块或进入夹层•Physicians rely on tactile feedback to learn about the vessel anatomy andcontrolsteering the wire医生根据触觉反馈来判断血管的解剖走行，并操控导丝•A guide wire torque device is used tofacilitate
