摘要：
Tool assemblies, system, and methods for manipulating tissue and methods for performing a surgical procedure on a vertebral body adjacent soft tissue. A manipulator moves an end effector, and a screw is coupled to the end effector. A sleeve is disposed coaxially around the screw, and the screw and the sleeve are releasably engaged to one another. A navigation system is configured to track the vertebral body, and one or more controllers control the end effector to advance the screw relative to the sleeve along an insertion trajectory defined with respect to a surgical plan. The screw disengages the sleeve during advancement, and the screw is secured to the vertebral body. A distal working portion of the screw may be freely slidable through a distal end of the sleeve when disengaged. The screw may be a tap marker removably couplable with a tracking device of the navigation system.
