A surgical incise drape (10, 80, 90, 120, 103, 160) comprising a flexible film having a leading edge (31) and a trailing edge (32), and a film handle (18, 86) connected to the leading edge (31) of the flexible film (12, 81, 91, 122, 162). A liner (16, 83, 94, 125, 166) substantially covers the major portion of the flexible film (12, 81, 91, 122, 162), which is coated with an adhesive (14, 81, 99, 124, 163). The liner (16, 83, 94, 125, 166) may include a liner handle (22) at the leading edge (35), and one of the liner handle (22) and film handle (18, 86) are of a size for wrapping about at least a portion of the drape (10, 80, 90, 120, 103, 160) when the drape (10, 80, 90, 120, 103, 160) is in a folded configuration. A tensioning strip (20, 84, 98, 128, 104, 168, 169) on the liner (16, 83, 94, 125, 166) holds at least a portion of the flexible film (12, 81, 91, 122, 162) lying between the film handle (22, 86) and the tensioning strip (20, 84, 98, 128, 104, 168, 169) in a wrinkle-free state when the liner (16, 83, 94, 125, 166) is being removed from the major portion of the flexible film (12, 81, 91, 122, 162). Further, the liner (16, 83, 94, 125, 166) may be stiff relative to the flexible film (12, 81, 91, 122, 162) such that the liner (16, 83, 94, 125, 166) and the film handle (18, 86) hold the flexible film (12, 81, 91, 122, 162) in a wrinkle-free state when the liner (16, 83, 94, 125, 166) is being removed from the major portion of the flexible film (12, 81, 91, 122, 162). Methods for using these surgical incise drapes, tear lines (208, 308), and connecting or reinforcement strips (302) are also described.

L'invention concerne un champ stérile (10, 80, 90, 103, 120, 160) pour incision chirurgicale constitué d'un film souple comprenant un bord avant (31) et un bord arrière (32), et d'une main du film fixée au bord avant (31) du film souple (12, 81, 91, 122, 162). Une doublure (16, 83, 94, 125, 166) recouvre sensiblement la majeure partie du film souple (12, 81, 91, 122, 162) revêtu d'un adhésif (14, 81, 99, 124, 163). La doublure (16, 83, 94, 125, 166) comprend éventuellement une main de doublure (22) sur le bord avant (35); la main de la doublure (22) ou la main du film (18, 86) présente une dimension permettant d'envelopper au moins une partie du champ stérile (10, 80, 90, 103, 120, 160) lorsque ce dernier est dans une configuration pliée. Une bande de tension (20, 84, 98, 104, 128, 168, 169) sur la doublure (16, 83, 94, 125, 166) retient au moins une partie du film souple (12, 81, 91, 122, 162) s'étendant entre la main du film (18, 86) et la bande de tension (20, 84, 98, 104, 128, 168, 169) pour éviter que cette partie ne présente des plis de froissement lorsque la doublure (16, 83, 94, 125, 166) est retirée de la majeure partie du film souple (12, 81, 91, 122, 162). En outre, la doublure (16, 83, 94, 125, 166) peut être rigide par rapport au film souple (12, 81, 91, 122, 162), si bien que la doublure (16, 83, 94, 125, 166) et la main du film (18, 86) retiennent le film souple (12, 81, 91, 122, 162) de manière à empêcher qu'il ne présente des plis de froissement lorsque la doublure (16, 83, 94, 125, 166) est retirée de la majeure partie du film souple (12, 81, 91, 122, 162). L'invention concerne en outre des procédés d'utilisation de champs stériles pour incision chirurgicale, des lignes de perforation (208, 308) et des bandes de raccordement ou de renfort (302).
