Electrosurgical Connection Unit

Abstract: Electrosurgical connection units for a surgical robot arm. The electrosurgical connection units include: an input port connectable to an electrosurgical generator; an output port connectable to an electrosurgical instrument attached to the surgical robot arm; one or more activation switch units, wherein activation of an activation switch unit of the one or more activation switch units causes an activation signal to be output from the input port, the activation signal is configured to, when the input port is connected to the electrosurgical generator, cause the electrosurgical generator to generate a driving electrosurgical signal which is received on the input port; a connection switch unit, wherein activation of the connection switch unit causes a portion of the input port to be electrically connected to the output port such that, when the input port is connected to the electrosurgical generator, the driving electrosurgical signal received on the input port is output on the output port; and a control unit configured to, in response to receiving a control signal from an external computing device, cause the connection switch unit to be activated and subsequently cause an activation switch unit of the one or more activation switch units to be activated.
