Surgical instruments

摘要

A spinal surgical system includes a surgical instrument (30) with a first member (40) mountable to a first vertebra and a second member (70) mountable to a second vertebra. The first and second members are coupled to one another with a coupling mechanism (90) that allows translation of the first and second members relative to another along a predetermined path. The coupling mechanism also provides a pivot axis about which the first and second members are manipulated relative to one another to deliver forces to the first and second vertebrae.
