摘要:
A teleoperated system includes a robotic arm configured to support an instrument, a grip configured to be manipulated by an operator to command motion of the instrument, and a control system communicatively coupled to the robotic arm and the grip. To align the grip with the instrument by the grip, the control system is configured to determine grip rotation values describing an orientation of the grip, determine instrument rotation values describing an orientation of the instrument, determine an orientation error between the orientation of the grip and the orientation of the instrument based on the grip rotation values and the instrument rotation values, produce a motion command by selectively imposing, based on the orientation error, an artificial joint limit on a commanded movement of the instrument, and command the robotic arm to move in accordance with the motion command.

A teleoperated system includes a master grip and a ratcheting system coupled to the master grip. The ratcheting system is configured to align the master grip with a slave instrument commanded by the master grip by determining a grip orientation by which the master grip is gripped by an operator, determining a commanded velocity for the slave instrument based on a manipulation of the master grip by the operator, determining an error, and altering the commanded velocity for the slave instrument based on at least the grip orientation and the error. The error includes a parameter selected from a group consisting of a position error between a position of the master grip and a position of the slave instrument and an orientation error between an orientation of the master grip and an orientation of the slave instrument.

Systems and methods for performing robotically-assisted surgical procedures on a patient enable an image display device to provide an operator with auxiliary information related to the surgical procedure, in addition to providing an image of the surgical site itself. The systems and methods allow an operator to selectively access and reference auxiliary information on the image display device during the performance of a surgical procedure.

摘要:
A minimally-invasive surgical system includes a slave surgical instrument having a slave surgical instrument tip and a master grip. The slave surgical instrument tip has an alignment in a common frame of reference and the master grip, which is coupled to the slave surgical instrument, has an alignment in the common frame of reference. An alignment error, in the common frame of reference, is a difference in alignment between the alignment of the slave surgical instrument tip and the alignment of the master grip. A ratcheting system (i) coupled to the master grip to receive the alignment of the master grip and (ii) coupled to the slave surgical instrument, to control motion of the slave by continuously reducing the alignment error, as the master grip moves, without autonomous motion of the slave surgical instrument tip and without autonomous motion of the master grip.

A teleoperated system includes a master grip and a ratcheting system coupled to the master grip. The ratcheting system is configured to be coupled to a slave instrument. The ratcheting system is further configured to align the master grip with the slave instrument by determining a commanded angular velocity for the slave instrument based on a command from the master grip, determining a current alignment error between an alignment of the master grip and an alignment of the slave instrument, and altering the commanded angular velocity for the slave instrument based on the current alignment error. In some embodiments, the ratcheting system is further configured to introduce a control system error to alter the commanded angular velocity. In some embodiments, the current alignment error is a rotation angle error between the alignment of the master grip and the alignment of the slave instrument.
