Device for providing a sterile limited space for surgery

A device for introducing sterile instruments into an operation chamber or an instrument chamber comprising:

• an introduction frame;
• and
• a first roller and a second roller arranged rotatable around their respective longitudinal axis, and attached to the introduction frame, wherein the longitudinal axis of the first roller and the longitudinal axis of the second roller are parallel, and the first roller and the second roller are attached to the introduction frame so as to be moveable along an axis extending perpendicular to their respective longitudinal axis;
• wherein a distance between the first roller and the second roller is defined by a position of a movement of the first and second roller along the axis extending perpendicular to their longitudinal axes;
• wherein the first and second rollers are biased to contact each other and the first and second roller are moveable along the axis extending perpendicular to their longitudinal axes to increase the distance to allow insertion of an instrument through a gap defined by the distance;
• and
• wherein the introduction frame is attached to a first inflatable bag of an isolation device for providing a sterile operation chamber above a skin region of a patient, the isolation device comprising:
• the first inflatable bag delimiting the sterile operation chamber against the ambient environment, the first inflatable bag comprising a first and a second access opening to allow a user to insert a first arm and a second arm into the operation chamber, and wherein the first inflatable bag is coupled to a support frame having a transport configuration and an operation configuration, wherein while in the transport configuration, the first inflatable bag is confined so as to have compact dimensions, and while in the operation configuration, the first inflatable bag is extended to form the sterile operation chamber;
• a chamber operation opening to allow access to the skin region of the patient;
• and
• a window for observing handling operations inside the sterile operation chamber.

• and
• an assisting device for donning and removing a surgical glove arranged inside the first inflatable bag, the assisting device comprising at least one fluid-tight wall arrangement encompassing an inner space having a volume of such a size that at least a palm portion and finger portions of the surgical glove can be arranged in the inner space, and an opening adapted to sealingly engage a cuff portion of the surgical glove if the palm portion and the finger portions are arranged in the inner space, wherein the fluid tight wall arrangement is adapted to be transformed from a first configuration into a second configuration and vice-versa, wherein, while in the first configuration, the inner space has a first inner volume, and wherein, while in the second configuration, the inner space has a second inner volume, the first volume being smaller than the second volume.

• wherein a distance between the first roller and the second roller is defined by a position of a movement of the first and second roller along the axis extending perpendicular to their longitudinal axes;
• and
• wherein the first and second rollers are biased to contact each other to form a closed condition wherein the rollers completely seal an opening and the first and second roller are moveable along the axis extending perpendicular to their longitudinal axes to increase the distance and thus form a gap in the opening to allow insertion of an instrument through the gap defined by the distance.
