Zusammenfassung:A colpotomy device for performing a hysterectomy is provided. The device includes a flexible drive tube having a proximal end and a distal end and bendable therebetween. The device also has a rotatable cutting implement at the distal end of the flexible drive tube at a specified offset from a bendable longitudinal axis of the flexible drive tube. Furthermore, the device includes couplings located within the flexible drive tube and rotatable about the bendable longitudinal axis of the flexible drive tube. The couplings can be in a series that includes inter-coupling joints and transmits a rotational force between the proximal and distal ends of the flexible drive tube through a variable angle between the couplings. The variable angle can correspond to bending of the drive tube in order to drive rotation of the cutting implement at the specified offset about the axis of the flexible drive tube.
