    摘要: Apparatus is provided for accessing a body cavity comprising a tubular member having a deflated insertion configuration and an inflated expanded configuration that facilitates viewing within the body cavity. The apparatus is formed by everting a length of material upon itself to form a tube having a single circumference seam at the distal end, and includes an inflation tube that is sufficiently rigid to assist in inserting the tubular member into a body cavity in the deflated insertion configuration. The tubular member further includes a pattern of staggered contact areas that configured so as to avoid the creation of longitudinal features that preferentially bend when loaded, thereby ensuring that tubular member provides a substantially circular central lumen.

    摘要: A device for the collection and removal of body tissue and/or parts in laparoscopic surgery having an elongated tubular member with proximal and distal extremities and a bore extending therethrough. A sack formed of a flexible material with an opening therein is secured by a rod inside the tubular member to the distal extremity of the elongated tubular member. A drawstring is secured to the sack and circumscribes the opening of the sack and controls the opening and closing of the sack. The drawstring extends into the bore and is connected to a slide mounted around the tubular member. A handle is secured to the proximal extremity of the tubular member and finger rings are secured to the proximal extremity of the slide. Movement of the slide towards the distal extremity of the tubular member opens the sack once inside the patient for receiving the tissue or body part, while movement of the slide in a distal direction causes the sack to close to capture the tissue or body part.
