A sterile case for an electronic device used during medical procedures includes a rigid housing with at least one transparent face. An opening in the housing permits movement of the device into and out of the housing in, for example, a direction parallel to the length or width of the housing. A door attached to the housing moves between open and closed positions to seal the opening. A sleeve is configured to be received, when the door is in the open position, partially within the housing and to extend outward from the housing through the opening. The sleeve defines a bore aligned with the opening and configured to receive the device and to permit insertion of the device through the sleeve into the housing without contact between the device and a rim of the housing surrounding the opening.
