摘要： An insert (70) for a clamping element with two jaws to clamp a rod-shaped element comprises an inner cavity (144) to accommodate a rod-shaped element and at least one flange element (153) at one longitudinal end of the insert intended to abut against the clamping element. The flange element (153) comprises clamping members (161) to reduce the available room within the inner cavity (144) for the rod-shaped element to be clamped and to clamp the flange element (153) between the rod-shaped element and an outer clamping surface of the clamping element to prohibit any longitudinal movement of the clamped insert.

摘要： A two-piece clamping element comprises two separate, i.e., non-integral, opposing first and second clamping jaws forming a laterally open cavity to receive a pin or rod-shaped element. Each clamping jaw has a bore aligned with one another to receive a screw, wherein a pivot bearing is arranged opposite said cavity allowing the two opposing clamping jaws to come in contact to one another. The pivot bearing comprises at least one set of complementary part-cylindrical bearing surface portions. An anti-rotation pin extends between the two jaw members.

摘要： A screw fastener for attachment to an orthopedic component such as an orthopedic plate for use in connection with fracture fixation, joint reconstruction or spinal stabilization or fusion is disclosed as having a shank with at least two different shank diameters, one in a plate engaging portion of the shank and one in the bone or other component engaging portion of the shank. At least two of the different shank diameters on the shank include threads, the threads on the two different diameter portions each having substantially the same thread height and pitch. A plate having a threaded aperture, or an adapter having a threaded aperture, is sized such that the threads of the smaller diameter shank portion engage and cooperate with the internal threads of the aperture to correctly align the screw fastener and the implant as the screw fastener is threaded through the implant. The threads on the larger diameter shank portion and the internal threads of the aperture of the implant are sized so that the threads of the larger diameter shank portion are fully engaged with the internal threads of the orthopedic implant.

摘要： 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 at least one clamping assembly having a pair of jaws with at least two different size grooves to accommodate a bone fixation element such as a pin or rod. An alternate clamping assembly has at least three grooves wherein at least two of the grooves have a different size adapted to accommodate a correspondingly sized bone fixation element such as a bone pin. The longitudinal axes of the grooves define a polygon. The jaw pairs can be rotated about a central longitudinal axis to present different size reception cavities towards the pins or rocks depending on their diameter.

摘要： Described herein are external fixation systems for correcting bone deformities in adjacent bones or fragments thereof. The systems herein include first and second elongate rods that translate with respect to one another via rotation of an actuation member at an end of one of the rods. At least one housing is coupled along a length of one of the rods. The at least one housing includes at least one pin clamping member for clamping an end of a fixation pin therein. When the at least one pin clamping member is in an unlocked state, the fixation pin can rotate in polyaxial directions. When in a locked state, the angle of fixation wire with respect to the rods is set. The locked and unlocked state of the at least one pin clamping member is determined by the positing of a fixation member with respect to the housing it is coupled to.

摘要： An external fixation system and method for realigning, compressing or distracting broken bones has a planar ring element with an adjustable device having a body releasably mounted on the ring element. The adjustable device includes a first member for movement in a direction generally perpendicular to the ring element. A second member is pivotally connected to the first member for angular movement with respect to the ring. A third member is mounted on the second member for movement in a direction parallel to the second member and with respect to a circumference of the planar ring element. The method includes inserting k-wires into bone and affixing the k-wires to the ring element and affixing the k-wires to an adjustable device. The pieces of bone are realigned, compressed or distracted by adjusting at least one of a first and second members forming the device.

摘要： An easy to clean clamping device has at least one clamping assembly having two jaws. The jaws form at least one recess to accommodate an element to be clamped along the longitudinal axis of the recess. A locking unit is provided to allow closing of the jaws against the force of a spring element. The locking unit has a shaft extending along an axis and through bores of the jaws. The shaft has a head for operating the clamping action abutting against the uppermost jaw. A locking element is provided having a through bore and which locking element can be arranged between the head and the uppermost jaw. One portion of the locking unit has a larger diameter than the bore of the second jaw and the head of the locking unit has a smaller diameter than the bore of the adjacent jaw. The locking element comprises at least one locking surface which can be brought into positive locking with a corresponding surface of the head for blocking removal of the locking element.

摘要： A clamping pin is provided for mounting in an opening of a medical device. The clamping pin comprises an axially extending screw, a first clamping element having a surface inclined to a longitudinal screw axis and provides a first part of a clamping section. A second clamping element has a surface inclined to the longitudinal axis and provides a second part of the clamping section which is complementary to the opening in the medical device. The inclined surfaces of the first and second clamping elements contact. A screw extends at least partly through both the first and second clamping elements. The screw engages one of the clamping elements such that the axial distance between the two clamping elements and the diameter of the clamping section that can come in contact with a surface of the opening in the medical device will be changed upon actuation of the screw.
