Abstract
A surgical instrument system is disclosed. The surgical instrument system includes an instrument case and a charging plate that may be placed in a sterile surgical field. The charging plate is configured to receive electrical power from outside the sterile surgical field and transmit that electrical power to other devices within the sterile field.
Claims20
A surgical instrument system, comprising:
- a metallic instrument case including a bottom wall and a number of side walls extending upwardly from the bottom wall to define a chamber sized to receive a plurality of surgical instruments,
- a lower housing secured to the bottom wall of the metallic instrument case, the lower housing including a first induction coil, and
- an upper housing positioned in the chamber of the metallic instrument case, the upper housing including a second induction coil that is electrically connected to the first induction coil through one or more openings defined in the bottom wall of the metallic instrument case.
A surgical instrument system comprising:
- an instrument case including bottom wall and a number of side walls extending upwardly from the bottom wall to define a chamber sized to receive a plurality of surgical instruments,
- a lower housing secured to the bottom wall of the instrument case, the lower housing including a first induction coil and a first connector;
- the first connector configured to secure the lower housing the instrument case, having a first flange, a first electrical connection, and an inner hub,
- an upper housing positioned in the chamber of the instrument case, the upper housing including a second induction coil that is electrically connected to the first induction coil through one or more openings defined in the bottom wall of the instrument case, and a second connector, and
- the second connector configured to secure the upper housing to the instrument case, having a second flange, and a second electrical connection.

A method for providing power to a sterile environment, the method comprising:
- selecting an instrument case to be positioned within the sterile environment, wherein the instrument case includes a bottom wall and a number of sidewalls that extend upwardly from the bottom wall to define a chamber sized to receive a plurality of surgical instruments,
- attaching a lower housing to a bottom surface of the bottom wall of the instrument case, the lower housing including a first inductive coil adapted to wirelessly interact with a second inductive coil spaced apart from the first inductive coil,
- positioning an upper housing in the chamber of the instrument case, the upper housing including a third inductive coil,
- coupling the upper housing to the lower housing such that the first inductive coil of the lower housing is electrically connected with the third inductive coil of the upper housing, and
- energizing the second inductive coil to supply power to the third inductive coil through the first inductive coil.
