Ratcheting for master alignment of a teleoperated minimally invasive surgical instrument
First Claim
1. A teleoperated system comprising:
- a master grip; and
a ratcheting system coupled to the master grip and configured to be coupled to a slave surgical instrument having a slave surgical instrument tip, the ratcheting system being configured to align the master grip with the slave surgical instrument tip,the ratcheting system comprising;
an introduce control system error controller configured to introduce a control system error between a slave surgical instrument tip alignment and a master grip alignment to speed up convergence of alignment between the slave surgical instrument tip and the master grip relative to convergence of alignment between the slave surgical instrument tip and the master grip without introduction of the control system error.

Abstract
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.

17. A method comprising:
aligning, by a controller, a master grip of a teleoperated system with a slave surgical instrument tip of a slave surgical instrument of the teleoperated system by introducing a control system error between a slave surgical instrument tip alignment and a master grip alignment to speed up convergence of alignment between the slave surgical instrument tip and the master grip relative to convergence of alignment between the slave surgical instrument tip and the master grip using without introducing the control system error. - View Dependent Claims (18, 19, 20, 21)
