A DEVICE FOR PROVIDING A STERILE LIMITED SPACE FOR SURGERY

摘要

Device for introducing sterile instruments into an operation chamber or an instru-ment chamber, comprising: an introduction frame; a first roller and a second roller arranged rotatable around their respective longitudinal axis, and attached to said introduction frame, such that the longitudinal axis of the first roller and the longitudinal axis of the second roller are parallel, wherein the first roller and the second roller are further attached to said introduction frame such as to be movable along an axis extending perpendicular to their respective longitudinal axis; wherein a distance between the first roller and the second roller is determined by a position of a movement of the first and second roller along the axis extending perpendicular to the longitudinal axes, wherein said first and second rollers are biased versus each other to contact each other and said first and second roller can be moved along said axis to increase said distance to allow insertion of an instrument through a gap provided by said distance.
