Orthopedic device
View Patent ↗An orthopedic device includes a fixator body having a first part and a second part that are connected by a joint and having an internally threaded bore extending longitudinally therethrough. A first pair of opposed longitudinally extending slots is provided in the first part and a second pair of opposed longitudinally extending slots is provided in the second part. A first and second pin-holders are received within and threadably engage the internally threaded bore of the first part and the second part, respectively, and are configured to removably hold a first and second sets of one or more bone fixation pins extending through the first and second pairs of opposed longitudinally extending slots, respectively.
1. An orthopedic device for fixating bone parts using two sets of one or more bone fixation pins, said device comprising:
an elongated fixator body having a first end and a second end and having an internally threaded bore extending longitudinally therethrough;
a pair of opposed longitudinally extending slots provided in the fixator body near the first end; and
a slidable sleeve slidably provided over the fixator body for capturing and translating a first set of the one or more bone fixation pins, the slidable sleeve comprising:
a longitudinally extending bore in which the fixator body is slidably received; and
a pair of diametrically opposed holes provided for receiving each of a first set of one or more bone fixation pins, the pair of opposed holes being aligned with said pair of opposed longitudinally extending slots, each pair of opposed holes receiving one of the bone fixation pins from the first set of one or more bone fixation pins, the bone fixation pins being translated and locked by the slidable sleeve wherein when the bone fixation pins from the first set of one or more bone fixation pins are received in the corresponding pair of opposed holes, the bone fixation pins are also extending through the pair of opposed longitudinally extending slots; and
a driving set screw received in the first end of the fixator body and threaded into the internally threaded bore of the fixator body wherein when threading the driving set screw into the internally threaded bore of the fixator body, the driving set screw pushes against the bone fixation pins causing the bone fixation pins and the slidable sleeve to slide longitudinally together along the fixator body.
2. The orthopedic device of claim 1 , further comprising at least one pair of diametrically opposed pin holes provided in the fixator body near the second end.
3. The orthopedic device of claim 2 , wherein each pair of the at least one pair of diametrically opposed pin holes is configured for receiving one of the one or more second set of bone fixation pins through the fixator body.
4. The orthopedic device of claim 2 , further comprising a locking set screw received in the second end of the fixator body and threadably engaging the internally threaded bore of the fixator body for locking the second set of bone fixation pins received through the at least one pair of diametrically opposed pin holes provided in the fixator body near the second end.
5. The orthopedic device of claim 1 , further comprising an offset pin clamp provided at the second end of the fixator body for securing a second set of one or more bone fixation pins, wherein the offset pin clamp holds the second set of one or more bone fixation pins offset from the fixator body.
6. The orthopedic device of claim 5 , wherein said offset pin clamp comprises:
a longitudinally extending bore in which the fixator body is received; and
one or more pin holes for receiving and holding said second set of one or more bone fixation pins.
7. The orthopedic device of claim 6 , wherein the one or more pin holes are provided in a portion of the offset pin clamp offset from the bore whereby the one or more pin holes do not intersect the bore.
8. The orthopedic device of claim 6 , further comprising a threaded hole for receiving a countersink-head screw.
9. The orthopedic device of claim 8 , wherein the threaded hole is oriented orthogonal to the bore and the one or more pin holes.
