  • Medical tubular shaft instrument and method for producing a force transmission element of the same
    Patent number: 8617202
    Abstract: A medical tubular shaft instrument having a tube and a force transmission element extending lengthwise through the tube. The tube includes a jaw member arrangement on a distal end, which is coupled with the force transmission element and actuated by sliding the force transmission element along the tube. The tube includes a handpiece on a proximal end. The force transmission element, over part of its length, has a smaller outer diameter than the inner diameter of the tube to configure a ring-shaped flushing canal, and, one section along its length, it is centered in the tube in this section. The force transmission element includes precisely one section in which it is centered in the tube, and the section is in the vicinity of the distal end of the force transmission element and is perpendicular to its longitudinal axis by reshaping the force transmission element.
