A fixation clamp, more particularly for use in an external fixation system for holding bone fragments adjacent to each other with the help of fixation elements, has at least one clamping assembly having at least one reception opening to accommodate a fixation element along the longitudinal axis of the reception opening. At least one locking element extends through the clamping assembly which locking element provides a clamping force to clamp the fixation element upon tensioning the locking element. The fixation clamp further comprises an actuation element which is in connection with the locking element such that the locking element is actuateable by the actuation element, and the actuation element is designed such that it is detachable from the locking element after use and that remounting onto the locking element is prevented after having detached the actuation element from the locking element.

Fixation clamp

A surgical clamping device is provided for receiving distal ends of handles having bone attachment members disposed thereon in a recess disposed in the surgical clamping device. When an adjustment mechanism is in a first state, the distal ends of the handles are able to pivot and, optionally, to move axially within the recess of the surgical clamping device. When the adjustment mechanism is placed into a second state by adjusting the adjusting mechanism, the surgical clamping device applies a clamping force to the distal ends of the handles such that they are fixed within the recess of the surgical clamping device.

Hinge coupling

A tool for breaking a shaft has a first and a second tubular element, both provided with inner through bores adapted to receive a shaft in the tool. A first handle is fixedly connected with the first tubular element and the second tubular element is connected to a second handle. A bottom surface of the second tubular element forms a shearing plane with a neck surface of the first tubular element. A rotation between the two tubular elements shears the shaft at the shearing plane. The second handle turns the first tubular element around an axis and has a gear engaging the second tubular element for transmitting the rotation of the second handle into a rotation of the second tubular element. The drive element is mounted offset, in a direction of the longitudinal axis, from the gear.
