US Patent 12011217 Electrosurgical instrument with modular component contact monitoring

An apparatus includes a shaft assembly, an end effector, a control module, a first electrical connector, and a plurality of nonconductive structures. The first electrical connector is operatively coupled with the control module and includes a first plurality of electrical contacts. At least one electrical contact of the first plurality of electrical contacts is configured to transfer a power output from the control module to a second plurality of electrical contacts of a second electrical connector while the first and second electrical connectors are coupled. The nonconductive structures are disposed adjacent each of the plurality of first electrical contacts. The nonconductive structures are configured to prevent a signal interference between each electrical contact of the first plurality of electrical contacts.
