    Abstract: An electrosurgical instrument is disclosed including a pencil-grip handle, a shaft coupled to the pencil-grip handle, and an end effector coupled to the shaft. The end effector includes a body, a source electrode, and one or more return electrodes. The source electrode and the one or more return electrodes are configured to provide a multi-phase bipolar electrosurgical signal to tissue. The one or more return electrodes each comprise a first return electrode and a second return electrode. The electrosurgical instrument further includes an electrosurgical generator coupled to the end effector. The electrosurgical generator is configured to produce the multi-phase bipolar electrosurgical signal including a first phase, a second phase, and a third phase. The electrosurgical generator is coupled to the source electrode, the first return electrode, and the second return electrode. The first phase, the second phase, and the third phase are combined to generate the multi-phase bipolar electrosurgical signal.

    Abstract: A surgical shaft assembly includes a slip ring assembly. The slip ring assembly has a first connector, a first conductor mounted on the first connector, and a first water-proof insulative layer on the first conductor. The slip ring assembly has a second connector rotatable relative to the first connector, a second conductor mounted on the second connector, and a second water-proof insulative layer on the second conductor. The slip ring assembly also has a dielectric layer located between the first water-proof insulative layer and the second water-proof insulative layer. The first conductor and the second conductor are configured to form a capacitive channel therebetween.

    Abstract: Various surgical hubs are disclosed. A surgical hub comprises a processor and a memory coupled to the processor. The memory stores instructions executable by the processor to: receive a first self-describing data packet from a first data source, the first self-describing data packet comprising a first preamble, a first data payload, a source of the first data payload, and a first encryption certificate, wherein the first preamble defines the first data payload and the first encryption certificate verifies the authenticity of the first data packet; parse the received first preamble; and interpret the first data payload based on the first preamble.
