The rod coupler according to the present invention comprises two clamping jaws and locking means for locking said clamping jaws against one another. Each clamping jaw comprises an outside surface and a clamping surface, the latter providing at least a first and a second groove. Each groove runs laterally from a different part of the outside surface extending into the rod coupler, wherein longitudinal axis of the first groove and the second groove include an angle that is equal to or less than 160 degrees. Opposing grooves form an aperture. The apertures are adapted for receiving a rod if the locking means is released. Clamping jaws that are locked by the locking means clamp the rods received in said apertures.

Rod coupler with variable ankle position

A fixation clamp for use in an external fixation system for holding bone fragments adjacent to each other with the help of fixation elements, has of at least one clamping assembly having at least one reception provided by means of grooves to accommodate a fixation element along the longitudinal axis of the reception. At least one locking element extends through the clamping assemblies for blocking the position of the clamping assemblies in a defined angular position. The clamping assembly comprises a first jaw and a second jaw which are in contact with each other via respective contact surfaces. The clamping assembly comprises at least two orientation devices that extend from and/or into said contact surfaces which at least two orientation devices serve to orient the first jaw with respect to the second jaw.

Fixation clamp

A fixation clamp is used in an external fixation system for holding bone fragments adjacent to each other with the help of fixation elements. The clamp has at least one clamping assembly having at least one reception to accommodate a fixation element along the longitudinal axis of the reception and at least one locking element extending through the clamping assemblies for blocking the position of the clamping assemblies in a defined angular position. Between the locking element and the at least one clamping assembly there is arranged a washer. The clamping assembly comprises a first contact surface and the washer comprises a second contact surface wherein the first contact surface is in contact with the second contact surface. The washer has a through bore and an opening extending radially from the bore to an outer surface of the washer.

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 with thumbwheel

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 means of 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.

Coupling element for an external fixator which connects a pin or rod to a second pin or rod. The coupling element comprises a first coupling section to clamp the first pin or rod in engagement with a second clamp for clamping the second pin or rod and a pivoting section for adjusting the orientation of the first coupling section relative to the post section in the space. The pivoting section extends along a third axis. The first coupling section is rotatable around a first axis with respect to the pivoting section and wherein via the pivoting section the first coupling section is pivotable around a second axis with respect to the post section, wherein the second axis is arranged at an angle to the first axis.

Hinge coupling

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 to accommodate a fixation element along the longitudinal axis of the reception and at least one locking element extending through the clamping assemblies for blocking the position of the clamping assemblies in a defined angular position. Between said locking element and said at least one clamping assembly there is arranged a washer. The clamping assembly comprises a first contact surface which is spherical and convex and in that said washer comprises a second contact surface which is spherical and concave, wherein the first contact surface is in contact with the second contact surface.
