Patent attributes
A surgical instrument manipulator comprises a manipulator arm and an instrument mounting structure rotatably mounted to the manipulator arm. The instrument mounting structure comprises: an attachment interface configured to removably couple to a surgical instrument; and a passage within the instrument mounting structure. When the surgical instrument is coupled to the attachment interface, the surgical instrument is fixed to the instrument mounting structure. An elongate body of the surgical instrument extends through the passage when the surgical instrument is coupled to the attachment interface. The instrument mounting structure is rotatable relative to the manipulator arm, and when the surgical instrument is coupled to the attachment interface, rotation of the instrument mounting structure with respect to the manipulator arm causes rotation of the surgical instrument.
