Surgical instruments with electrical connectors for power transmission across sterile barrier

A handle assembly of a surgical instrument system coupled to a surgical end effector having a first jaw and a second jaw movable relative to the first jaw, the handle assembly comprising:

• a disposable outer housing defining a sterile barrier, the disposable outer housing comprising:
• a first housing-portion;
• and
• a second housing-portion movable relative to the first housing-portion between an open configuration and a closed configuration;
• a control inner core receivable inside the disposable outer housing in the open configuration, wherein the disposable outer housing is configured to isolate the control inner core within the sterile barrier in the closed configuration, and wherein the control inner core comprises a motor assembly;
• an actuator, comprising:
• a pressure-sensitive actuation member, that extends across a cavity defined in a portion of an outer wall of the disposable outer housing, such that edges of the pressure-sensitive actuation member are aligned with sidewalls of the cavity to form a contiguous surface of the outer wall;
• and
• a magnetic field source positionable inside the disposable outer housing;
• a magnetic field sensor positionable within a sufficient proximity to the magnetic field source to measure at least one parameter of a magnetic field generated by the magnetic field source;
• a control circuit configured to:
• detect changes in the magnitude of an external actuation force applied to the pressure-sensitive actuation member based on measurements by the magnetic field sensor of the at least one parameter of the magnetic field;
• and
• adjust drive motions generated by the motor assembly in accordance with the detected changes in the magnitude of the external actuation force, wherein the drive motions generated by the motor assembly are configured to be adjusted proportionally with respect to the detected changes in the magnitude of the external actuation force;
• a wireless electrical interface assembly configured to effect at least one wireless transmission of at least one of data and power through the sterile barrier, the wireless electrical interface assembly positioned on a first side of the sterile barrier inside the disposable outer housing and a second side of the sterile barrier outside the disposable outer housing;
• and
• a wired electrical interface assembly configured to effect at least one wired transmission of the at least one of data and power through the sterile barrier, the wired electrical interface assembly positioned on the first side of the sterile barrier and the second side of the sterile barrier opposite the first side.
