Abstract: A sterile drape for a C-arm X-ray device includes a slide rail assembly configured to be connected to a C-arm of an X-ray device that extends from a lower portion of the C-arm to an upper portion of the C-arm. The sterile drape further comprises a sterile drape assembly comprising a length of compliant material, the sterile drape assembly configured to be detachably coupled to the upper portion of the C-arm and to the slide rail assembly. The sterile drape also comprises an anchor assembly configured to be connected to the C-arm X-ray device at one end and configured to be connected to the sterile drape assembly at the other end so that the anchor assembly draws the sterile drape assembly along the slide rail assembly as the C-arm is rotated.

Abstract: Sterile drapes for C-arm X-ray devices that allow users to easily maintain sterility in a surgical field as the C-arm is rotated or moved around a patient are described. The sterile drape contains a slide rail assembly configured to be connected to a C-arm of an X-ray device that extends from a lower portion of the C-arm to an upper portion of the C-arm, a sterile drape assembly comprising a length of compliant material, the sterile drape assembly configured to be detachably coupled to the upper portion of the C-arm and to the slide rail assembly, and an anchor assembly configured to be connected to the X-ray device at one end and configured to be connected to the sterile drape assembly at the other end so that the anchor assembly draws the sterile drape assembly along the slide rail assembly as the C-arm is rotated. The sterile drape is connected to the X-ray device so that one end of the sterile drape assembly remains in substantially the same position regardless of the movement of the C-arm.
