Abstract
A surgical cannula includes an electrically conductive portion, an electrical connector interface configured to removably engage with an electrical connector electrically coupled to a patient return electrode, and an electrical connector sensing device configured to sense whether the electrical connector interface is engaged or disengaged with the electrical connector. Surgical systems include surgical cannulas. Methods relate to surgical cannulas.
Claims20
A surgical cannula, comprising:
- an electrically conductive portion;
- an electrical connector interface configured to removably engage with an electrical connector electrically coupled to a patient return electrode;
- and
- an electrical connector sensing device configured to sense whether the electrical connector interface is engaged or disengaged with the electrical connector.

A surgical system, comprising:
- a surgical manipulator;
- a cannula, comprising:
- an attachment portion configured for attachment to the surgical manipulator;
- an electrical connector interface configured to removably engage with an electrical connector electrically coupled with a patient return electrode;
- and
- an electrical connector sensing device configured to provide information to a controller of the surgical system regarding an engaged or disengaged state of the electrical connector with the electrical connector interface.
3 more elements
A method comprising:
- positioning an electrode in conductive contact with an electrically conductive body;
- engaging an electrical connector operatively coupled to the electrode to an electrical connector interface of a surgical cannula, wherein the engaging electrically couples the electrical connector and the electrical connector interface of the surgical cannula;
- and
- changing a state of an electrical connector sensing device responsive to the engaging of the electrical connector and the electrical connector interface of the surgical cannula.
