Abstract
Various exemplary methods, systems, and devices for controlling a motor of a robotic surgical system are provided.
Claims20
A surgical apparatus, comprising:
- a motor of a robotic surgical system, the motor being configured to provide torque to a surgical tool removably and replaceably coupled to the robotic surgical system, and the motor including a first plurality of magnets configured to generate a first electromagnetic field and a second plurality of magnets configured to generate a second electromagnetic field, wherein the motor is configured to provide a first amount torque to the surgical tool and a second amount of torque to the surgical tool in response to interference of the second electromagnetic field with the first electromagnetic field.
A surgical method, comprising:
- causing a motor of a robotic surgical system to generate a first electromagnetic field to provide a first amount of torque to a surgical tool removably and replaceably coupled to the robotic surgical system and thereby causing movement of the surgical tool;
- and
- causing the motor to generate a second electromagnetic field to interfere with the first electromagnetic field such that the first amount of torque being provided to the surgical tool is adjusted to a second amount of torque.
A surgical apparatus, comprising:
- a motor of a robotic surgical system, the motor being configured to generate a first electromagnetic field to provide a first amount of torque to a surgical tool removably and replaceably coupled to the robotic surgical system, and the motor being configured to generate a second electromagnetic field that is configured to interfere with the first electromagnetic field and thereby adjust the first amount of torque to a second amount of torque that is different than the first amount of torque.
