The present disclosure describes systems and methods for selectively constraining an orientation of a portion of a surgical tool system relative to another. Example surgical tool systems may include a surgical tool having at least one movable component (208), at least one actuation component (214) and a surgical tool attachment (300a). The surgical tool attachment may be operable selectively to engage and disengage the moveable component so as to to prevent movement of the movable component relative to the surgical tool in an engaged configuration and to permit movement of the movable component relative to the surgical to in a disengaged configuration, respectively. In the engaged configuration, a dynamic component of the surgical tool system may be fixed relative to the surgical tool, and, in a disengaged configuration, the dynamic component may be freely movable relative to the surgical tool.
