Patent number: 9561045Abstract: The invention provides surgical or diagnostic tools and associated methods that offer improved user control for operating remotely within regions of the body. These tools include a proximally-located actuator for the operation of a distal end effector, as well as proximally-located actuators for articulational and rotational movements of the end effector. Control mechanisms and methods refine operator control of end effector actuation and of these articulational and rotational movements. A rotation lock provides for enablement and disablement of rotatability of the end effector. The tool may also include other features. A multi-state ratchet for end effector actuation provides enablement-disablement options with tactile feedback. A force limiter mechanism protects the end effector and manipulated objects from the harm of potentially excessive force applied by the operator.Type: GrantFiled: April 16, 2007Date of Patent: February 7, 2017Assignee: Intuitive Surgical Operations, Inc.Inventors: Cameron D.
