Patent number: 11801103Abstract: A surgical system includes: a tool manipulator having a tool manipulator arm and a surgical tool; a console having a handling tool configured to receive a tool movement input of a surgeon for the surgical tool, the console being configured to transmit a tool movement command generated based on the tool movement input, the tool movement input including a translation amount and a rotation amount for the surgical tool; and a controller. The controller is configured to calculate an actual translation amount by multiplying the translation amount by a predetermined translation scale factor and move the surgical tool in accordance with the actual translation amount, and to calculate an actual rotation amount by multiplying the rotation amount by a predetermined rotation scale factor and move the surgical tool in accordance with the actual rotation amount. The translation scale factor and the rotation scale factor are different values.Type: GrantFiled: April 29, 2019Date of Patent: October 31, 2023Assignees: KAWASAKI JUKOGYO KABUSHIKI KAISHA, MEDICAROID CORPORATIONInventors: Tsuyoshi Tojo, Kenji Noguchi, Tetsushi Ito, Tetsuya Nakanishi
