Abstract
Abstract A surgical isolation drape for use in urological, gynaecological or proctorlogical surgical procedures or examination of patients comprises a sheet (10) of flexible transparent or translucent plastics material provided with adhesive strips (13, 14) and/or tapes (131, 141) for attaching the upper end of the sheet to the patient's legs so that the remainder of the sheet hangs down therefrom. The lower portion of the sheet is formed into a funnel (30) either by seaming its edge portions (221, 231) together or by means of attachment means such as tapes (15 to 20) for joining the sides of the lower part of the sheet. A central part of the sheet is provided with apertures (24, 25) sealed by flexible members such as surgical gloves (26, 27) which permit passage of the surgeon's hands. For urological use, the central portion also ha a sealable aperture (28) permitting ocular access to the lens of a urological instrument and a support for the lens casing, e.g. a reinforcing ring (29) and a box (34) or sheet (36) attached to the sheet (10). A self-adhesive flap (41) may also be used to protect the lens. For gynaecological use, the aperture (28) is replaced by a sealed inspection window.
