Abstract
A protector girdle to be wrapped around an endoscopic insertion instrument prior to introduction into a body cavity through a cannula of a trocar for protecting a soft skin layer on a flexible section of the insertion instrument from sharp edges at the fore end of the cannula. The protector girdle is formed of a generally rectangular sheet of rigid and slippery material with a restorative spring force, and provided with an adhesive band zone defined in a predetermined width along one side of the rectangular sheet, and a large number of elongated flap cover strips cut in the remainder of the sheet material in a predetermined pitch along the adhesive band zone and having free ends on the other side of the sheet remote from the adhesive band zone. When the protector girdle is fitted on an endoscopic insertion instrument, a soft skin layer in a flexible section is securely protected by the respective flap cover strips while passage through sharp edges at the fore end of a cannula.
