Bone plate and retractor assembly

摘要

A system for performing osteotomies includes a bone plate and a retractor assembly. The bone plate is operative for securing the relative positions between first and second portions of a bone that are separated by a gap. The bone plate generally includes a first mounting portion, a second mounting portion and an intermediate portion. The first mounting portion is for attachment to the first bone portion. The second mounting portion is for attachment to the second bone portion. The intermediate portion connects the first mounting portion and the second mounting portion in a first direction and has a central width in a second direction perpendicular to the first direction that is substantially less than a width of first and second ends. The retractor assembly establishes a wedge-shaped gap between the first and second portions of the bone. The retractor assembly generally includes first and second handle members and first and second jaw members. The second handle member is coupled to the first handle member for relative movement about a first pivot axis. The first jaw member has a first end coupled to a first end of the first handle member. The second jaw member has a second end coupled to a second end of the second handle member. The second jaw member includes a second end pivotally coupled to a second end of the second jaw member for relative movement about a pivot axis.
