Abstract
A robotic surgical tool includes a tool driver, and a drive housing inductively coupled to the tool driver when mounted to the tool driver and generating a magnetic field, the drive housing including one or more component parts made of or including a magnetically responsive material. A computer system is programmed to process an intensity of the magnetic field and a field distortion caused by the one or more component parts, and further programmed to generate a notification when the field distortion changes
Claims19
A robotic surgical tool, comprising:
- a tool driver;
- a drive housing inductively coupled to the tool driver when mounted to the tool driver and generating a magnetic field, the drive housing including one or more component parts made of or including a magnetically responsive material;
- and
- a computer system programmed to process an intensity of the magnetic field and a field distortion caused by the one or more component parts, and further programmed to generate a notification when the field distortion changes.
A method of operating a robotic surgical tool, comprising:
- mounting a drive housing to a tool driver, the drive housing including one or more component parts made of or including a magnetically responsive material;
- inductively coupling the drive housing to the tool driver and generating a magnetic field and a field distortion caused by the one or more component parts;
- processing with a computer system an intensity of the magnetic field and the field distortion;
- and
- generating a notification with the computer system when the field distortion changes.
A robotic surgical tool, comprising:
- a tool driver;
- a drive housing inductively coupled to the tool driver when mounted thereto and generating a magnetic field, the drive housing including a manual knife bailout system that includes one or more component parts selected from the group consisting of a bailout tool, a bailout panel, and a firing rod, wherein at least one of the one or more component parts is made of or includes a magnetically responsive material;
- a computer system programmed to process an intensity of the magnetic field and a field distortion caused by the one or more component parts, and further programmed to generate a notification when the field distortion changes.
