An electrosurgical connection unit for a surgical robot arm to connect an electrosurgical instrument attached to the arm to an electrosurgical generator. The electrosurgical connection unit includes an input port connectable to the electrosurgical generator, the input port configured to receive a driving electrosurgical signal and output one or more activation signals; an output port connectable to the electrosurgical instrument, the output port configured to output the driving electrosurgical signal received on the input port; one or more activation switch units, wherein activation of an activation switch unit causes an activation signal to be output from the input port indicating a driving electrosurgical signal with a desired waveform is to be activated; and a control unit configured to selectively activate one of the one or more activation switch units in response to a control signal.

Token-based electrosurgical instrument activation

A surgical robot comprising a robot arm base connected to a distal robot arm link via a series of intermediate articulated robot arm links. A robot arm interface is attached to the distal robot arm link. The robot arm interface engages an instrument interface of a surgical instrument, and comprises an instrument engagement source and an instrument engagement detector. The instrument engagement detector is configured to only detect the instrument engagement source when the instrument engagement source is coupled to the instrument engagement detector by a coupler.
