US Patent 11406464 Handle assemblies for robotic surgical systems

A robotic surgical system includes a robotic arm and a user interface. The robotic arm supports a jaw assembly that includes opposed jaw members defining a jaw angle therebetween. The user interface includes a handle assembly having a body portion, a handle controller disposed within the body portion, and a first actuator movable relative to the body portion to change an opening angle of the first actuator. The first actuator has a force profile which is a force required to move the first actuator as a function of the opening angle, and the jaw assembly has a jaw angle profile which is the jaw angle as a function of the opening angle.
