Surgical device, system and method of use thereof

摘要

The present invention includes a surgically implantable device, system, and method of use thereof for the internal compression or distraction of, for example, bone fractures, fusions, and osteotomies. More specifically, the surgical device comprises a bridge with one or more adjustable anti-reversing portions. The adjustable anti-reversing portion(s) may be located in a symmetrical or asymmetrical manner on the bridge between the device's legs. The adjustable anti-reversing portion(s) allow for stronger compression of the bone at a known amount of compression. The adjustable anti-reversing portion(s) can also maintain the device's legs in closer proximity to one another for greater compression or maintain the device's legs apart from one another for distraction. The surgical device can also comprise cannulated or grooved legs. A system and method of use is also described.

主权项

1. A surgical device for compression or distraction of a first body part relative to a second body part, comprising:
a bridge having a first aperture and a second aperture and at least one adjustable anti-reversing portion between said first and second apertures, said adjustable anti-reversing portion separating said bridge into a first section and a second section; a first leg and second leg, wherein said first leg is capable of being inserted through said first aperture and into said first body part, and said second leg is capable of being inserted through said second aperture and into said second body part; said adjustable anti-reversing portion allowing said first and second sections of said bridge to rotate relative to each other in one direction, but not in a reverse direction; wherein said first section of said bridge, said second section of said bridge, and said adjustable anti-reversing portion are coplanar with each other along a plane perpendicular to said first and second legs; wherein rotation of said first section of said bridge relative to said second section of said bridge maintains a coplanar relationship between said first section of said bridge and said second section of said bridge, and rotation of said first section of said bridge relative to said second section of said bridge maintains a perpendicular relationship between said bridge and each of said first and second legs; wherein said adjustable anti-reversing portion permits rotation between said first and second sections of said bridge along said plane, thereby permitting a user to adjust a relative angle and distance between said first and second legs; whereby said surgical device is capable of providing compression or distraction of said first body part relative to said second body part when said at least one adjustable anti-reversing portion is adjusted.
