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.
Claims19
A surgical cannula, comprising:
- a bowl portion comprising an opening to permit removable insertion of a medical instrument into the bowl portion;
- a tube portion extending distally from the bowl portion and configured to removably receive and permit advancement of a medical instrument inserted through the bowl portion;
- an electrical connector interface at the bowl portion and configured to removably engage with an electrical connector electrically coupled to a patient return electrode, a state of engagement of the electrical connector interface being either an engaged state, in which the electrical connector interface is engaged with the electrical connector, or a disengaged state, in which the electrical connector interface is removed from engagement with the electrical connector;
- and
- an electrical connector sensing device configured to sense whether the electrical connector interface is in the engaged state or in the disengaged state,
- wherein the electrical connector sensing device is coupled to the bowl portion and is movable relative to the bowl portion between a first physical configuration and a second physical configuration;
- the electrical connector sensing device is in the first physical configuration in the engaged state of the electrical connector interface;
- and
- the electrical connector sensing device is in the second physical configuration in the disengaged state of the electrical connector interface.

A surgical system, comprising:
- a surgical manipulator;
- a cannula configured to be removably mounted to the surgical manipulator, the cannula comprising:
- a bowl portion comprising an opening to permit removable insertion of a medical instrument into the bowl portion while the cannula is in a mounted state,
- a tube portion extending distally from the bowl portion and configured to removably receive and permit advancement of a medical instrument inserted through the bowl portion, and
- an electrical connector interface at the bowl portion and configured to removably engage with an electrical connector electrically coupled with a patient return electrode, a state of engagement of the electrical connector interface being either an engaged state, in which the electrical connector interface is engaged with the electrical connector, or a disengaged state, in which the electrical connector interface is removed from engagement with the electrical connector;
- an electrical connector sensing device arranged to sense the state of engagement of the electrical connector interface;
- and
- a controller operably coupled to the electrical connector sensing device, the controller receiving information from the electrical connector sensing device regarding the state of engagement of the electrical connector interface with the electrical connector,
- wherein the electrical connector sensing device is coupled to the bowl portion and is movable relative to the bowl portion between a first physical configuration and a second physical configuration;
- the electrical connector sensing device is in the first physical configuration in the engaged state of the electrical connector interface;
- and
- the electrical connector sensing device is in the second physical configuration in the disengaged state of the electrical connector interface.
