    • A device for removing a cerclage suture has a shaft sized and shaped to extend from a proximal end outside a vagina to a distal end near a cervix. The shaft also has a blunt end located at the distal end of the shaft and having a taper for allowing the blunt end to pass between a cerclage suture and cervical mucosa without cutting the mucosa and to move the suture away from the mucosa. The device includes a movable cutter at the distal end of the shaft and being movable between an open non-cutting position and a closed cutting position for cutting the suture. The device also includes an actuator for causing the cutter to be moved from the open position to the closed position to cut the suture.
    • 用于去除环扎缝合线的装置具有尺寸和形状从轴向外的近端延伸到子宫颈附近的轴。 该轴还具有位于轴的远端处的钝端,并且具有用于允许钝端在环形缝合线和子宫颈粘膜之间通过而不切割粘膜并使缝合线从粘膜移动的锥形。 该装置包括在轴的远端处的可移动切割器,并且可在打开的非切割位置和用于切割缝合线的封闭切割位置之间移动。 该装置还包括致动器,用于使切割器从打开位置移动到关闭位置以切割缝合线。
