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. | 11-12-2015 |
20150327937 | Skull Clamp - A skull clamp for patient stabilization comprises a pair of arms where the arms include upright portions and lateral portions. The upright portions and lateral portions define longitudinal axes, where the intersection of these axes defines an arm angle that is greater than about 90 degrees. In some instances the arm angle is between about 100 and about 120 degrees. In some instances the arm angle is about 110 degrees. The skull clamp can have rails integrated in the arms for attaching various accessories to the skull clamp. | 11-19-2015 |
20150342643 | Clamp - A clamp for a linkage for linking first and second bone fasteners of a prosthesis assembly, the clamp comprising a clamp body having a first receiving portion for receiving a first component of a prosthesis assembly and a second receiving portion for receiving a second component of the prosthesis assembly, the clamp having a deflectable member which deflects from a first position to a second position when one of the first and second components is introduced to its corresponding receiving portion, wherein when the deflectable member is in the second position and the other one of the first and second components is received by the clamp, the deflectable member is engageable with said other one of the first and second components. | 12-03-2015 |
20160000466 | MINI-RAIL EXTERNAL FIXATOR - 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. | 01-07-2016 |
20160038184 | EXTERNAL FIXATION - External fixation systems, and methods for immobilizing joints or fractured bones. An external fixation system may include one or more clamp assemblies connected to one or more rod assemblies at polyaxial joints. Each rod assembly may be length adjustable, and may include a one-way locking mechanism to provisionally lock the length of the rod assembly, and additional locking mechanisms to permanently lock the length of the rod assembly. The system may be deployed pre-assembled as a unit to immobilize a joint or fracture. Another external fixation system further includes a spanning member extending transverse to the rod assemblies. Two or more external fixation systems may be deployed in a stacked configuration on one set of bone pins to immobilize two joints and/or fractures. The systems may be provided in kits including guiding instrumentation, bone pins and pin clamping assemblies for connecting the bone pins to the external fixation systems. | 02-11-2016 |
20160038185 | EXTERNAL FIXATION SYSTEM WITH RADIO FREQUENCY SHIELDING - An electrical insulator is applied to a bone anchor, for instance of a bone implant, such as an external fixation frame, so as to prevent undesirable temperature increases in the bone anchor and surrounding anatomical tissue when subjected magnetic resonance imaging. | 02-11-2016 |
20160045226 | QUICK-RELEASE SYSTEMS FOR EXTRASKELETAL FIXATION - External fixation assemblies offer good benefits in relevant orthopedic procedures but would be used more efficiently if the quick-release fasteners could be used so no tools would be required. This invention covers various embodiments of quarter-turn, quick-release fasteners, various shapes and surfaces of connecting rods and bone pins or other clamped objects to facilitate use of external fixation assemblies. Connecting rods can have fastening positions in the form of threaded or non-threaded holes. Both holes and connecting rods and bone pins can be of different shapes, for example, round, square, oval, pentagonal, hexagonal, octagonal, or any arbitrary shape. In both adding holes and non-circular shapes, rotation is eliminated allowing better fixation, and, in the case of holes or dimpled or out-dented surfaces, longitudinal motion along the rod or pin as well. | 02-18-2016 |
20160081718 | EXTERNAL FIXATOR - A fixator for use in the reconstruction of acute, chronic and traumatic injuries to the upper and lower extremities. The fixator has a unique clamping system that allows for the snapping in of pins and rails, and for multi-planar fixation of bones. | 03-24-2016 |
20160095624 | CLAMPING DEVICE FOR USE WITH AN ANATOMIC EXTERNAL FIXATION SYSTEM - A clamping device for an external fixation system includes a clamp body and a locking assembly. The clamp body includes a first and second jaw that define a slot in communication with a first channel. The first channel can accommodate a first fixation element along a longitudinal axis of the first channel. The first jaw defines a first opening and the second jaw defines a second opening that are sized to receive a portion of the locking assembly. The locking assembly includes a first fastening element to pass through the first and second openings, and define a second channel to accommodate a bone pin. The locking assembly includes a second fastening element configured to engage with the first fastening element. The locking assembly is configured to restrict movement of the first fixation element and the bone pin relative to the clamp body in response to tightening of the locking assembly. | 04-07-2016 |
20160095626 | ANATOMIC EXTERNAL FIXATION SYSTEM FOR THE ANKLE - An external fixator system includes a proximal frame configured to restrict motion in a lower extremity of a subject, and a frame connector assembly. The proximal frame includes a first, second, and third component. The first component can support a first clamp to secure a first pin inserted within a bone extending between a foot and a knee of the lower extremity. The third component extends from a second end of the second component. The first, second and third components have longitudinal axes that are substantially coplanar. The third component includes an extension to extend over a dorsal portion of the foot of the subject and to support a second clamp to secure a second pin inserted within a bone of the foot. The frame connector assembly extends from the second component to support a third clamp to secure a third pin inserted within a third bone of the foot. | 04-07-2016 |
