RATCHETING FOR MASTER ALIGNMENT OF A TELEOPERATED MINIMALLY-INVASIVE SURGICAL INSTRUMENT

摘要

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.
