Transmission assembly for driving instrument motion, and related devices, systems and methods

Abstract

A medical instrument comprises an instrument shaft, a movable component coupled to the instrument shaft, a rotational actuation element extending through the instrument shaft and operably coupled to the movable component, and a transmission assembly movably coupled to the instrument shaft. The transmission assembly comprises a first drive member configured to drive translation of the instrument shaft relative to the transmission assembly, and a second drive member coupled to the rotational actuation element and configured to drive rotation of the rotational actuation element. Translation of the instrument shaft relative to the transmission assembly causes translation of the rotational actuation element relative to the transmission assembly.
