摘要:
A medical robotic system includes an entry guide with surgical tools and a camera extending out of its distal end. To supplement the view provided by an image captured by the camera, an auxiliary view including articulatable arms of the surgical tools and/or camera is generated from sensed or otherwise determined information about their positions and orientations and displayed on a display screen from the perspective of a specified viewing point. Intuitive control is provided to an operator with respect to the auxiliary view while the operator controls the positioning and orienting of the camera.

To perform a tool exchange in a medical robotic system, tool is retracted back into an entry guide from a deployed position and pose so that an assistant in the operating room may replace it with a different tool. While the tool is being retracted back towards the entry guide by user action, its configuration is changed to an entry pose while avoiding collisions with other objects so that it may fit in the entry guide. After the tool exchange is completed, a new tool is inserted in the entry guide and extended out of the guide by user action to the original position of the old tool prior to its retraction into the entry guide while the tool's controller assists the user by reconfiguring the new tool so as to resemble the original deployed pose of the old tool prior to its retraction into the entry guide.

A method is disclosed that includes outputting haptic feedback based on a movement of an object in a first direction from a first position to a second position. The haptic feedback is discontinued when the object is moved in a second direction opposite the first direction subsequent to the movement in the first direction. The haptic feedback is output again when the object moves past the second position in the first direction.

Methods and systems for a portable metrology device are described. One embodiment of the present invention is an apparatus including a first link, a first probe coupled with the first link by a first coupling operable to move in a first degree of freedom, a second probe coupled with the first link by a second coupling operable to move in a second degree of freedom, a first sensor operable to output a first sensor signal associated with a motion of the first coupling, and a second sensor operable to output a second sensor signal associated with a motion of the second coupling. The embodiment also includes a processor in communication with the first and second sensors and operable to: receive the first sensor signal and the second sensor signal, and determine a distance between the first probe and the second probe based at least in part on the first sensor signal and the second sensor signal.
