  • Patent number: 8951188
    Abstract: An element for transmitting pushing and pulling forces as well as torque having a straight configuration and a bent configuration comprises a base plate, an end plate and bellows arranged between the base plate and the end plate. The base plate and the end plate are connected with a connecting element. A plurality of washers is arranged within the bellows, the washers having a tronconical shape at at least one of their major surfaces. The washers are in mutual contact with each other or with the base plate or the end plate respectively, both in the straight configuration and the bent configuration, such that element can transmit pushing and pulling forces both in the straight configuration and the bent configuration without substantially changing the length of the element.
    Type: Grant

  • Patent number: 7896900
    Abstract: A medical instrument for grasping an object, in particular a surgical needle holder, including an elongated shaft, two jaw parts arranged at a distal end of the shaft, at least one of the jaw parts being pivotable with respect to the other of the jaw parts between a grasp state for grasping the object between the jaw parts and a release state for releasing the object. A handle is arranged at a proximal end of the shaft and has at least one operating element for moving the at least one pivotable jaw part between the grasp state and the release state via an axially movable force transmission element operatively connected with the at least one operating element and with the at least one pivotable jaw part via an articulated joint. The instrument further includes a latching mechanism for immobilizing the at least one pivotable jaw part in the grasp state.
