Abstract
A three-dimensional tilt ratchet mechanism that is able to rotate, pivot, and bend forwards or backwards with ease is provided. The mechanism includes a device for multi-dimensional movement and placement of a retractor blade which comprises a first member adapted to receive a stem of a retractor blade. The first member has a locking mechanism effective to enable selective lateral adjustment of the retractor blade relative to the first member. Also provided is a second member to which the first member is mated. The first member is vertically pivotable with respect to the second member to enable selective vertical pivoting adjustment of the retractor blade relative to the second member. A rotator indexing body is mated to the second member and is adapted to mount onto a rim of a surgical support. The second member is rotatable with respect to the rotator indexing body such that the first member, the second member and the retractor blade are able to selectively rotate about the longitudinal axis of the rotator indexing body.
