Abstract

A device to extract elements contained in cavities that uses a bag for their extraction that folds onto itself and an applier provided with an air chamber, which bag has pockets into which tentacles of the applier are introduced; and that is provided with means to pull from same; an applier that is comprised by a first piece called outer tube, that is hollow and of rigid material which, at its distal end, turns into at least two tentacles that allow its radial flexibility, and in its proximal end, means are provided to fix the second piece, called inner tube, which is a hollow tube, open at its ends, that slides into the body of the outer tube and that provides a funnel at its distal end. The device may have grade scale either on the tentacles, the inner tube as well as on the bag. Additionally, this provides two rings used as reference, on each of the folds of the bag.

Core Innovation

The invention relates to a device to extract elements contained in cavities, comprising a bag with pockets and means to extract the bag from a cavity. The bag is a tube of flexible transparent material folded onto itself at a fold, and comprises an air chamber adjacent to the fold between an outer portion of the bag and an inner portion of the bag. The air chamber is configured to be inflated/deflated through a conduit, and when inflated it is configured to reduce an inner circumference of the bag.

The device further comprises an applier with an advancement measuring indicator, and the air chamber and applier operate with the bag during extraction. The applier comprises two pieces: a first piece with an outer tube of rigid material whose distal end transitions into at least two tentacles or soft curved arms that are flexible, and a second piece with an inner tube that slides inside the outer tube and includes a funnel at a distal end of the inner tube. The pockets are shaped to receive the tentacles or the soft curved arms of the applier, and the inner portion of the bag is configured to move relative to the outer portion of the bag during extraction.

In the described configuration, the applier includes a chamber at a proximal end of the outer tube and an enlarged portion at a proximal end of the inner tube located inside the chamber, so the chamber restricts a sliding range of the inner tube with respect to the outer tube by restricting the sliding range of the enlarged portion. The advancement measuring indicator is implemented in the bag/applier arrangement to track advancement. The document also indicates that the system can include optional antiseptic/lubricant delivery via the inner tube and optional lighting/video camera integration.

Claims Coverage

The partial content provides two independent claims, each covering a cavity-extraction device with an inflatable/deflatable fold-adjacent air chamber and a two-piece applier. Across these independent claims, the inventive features focus on a flexible transparent folded bag with an air chamber reducing inner circumference, an applier with an advancement measuring indicator and funnel, pocket/arm engagement with relative bag portion movement during extraction, and sliding-range restriction in one independent claim.

Across the independent claims, the core coverage is a cavity-extraction device using a folded flexible transparent bag with a fold-adjacent inflatable/deflatable air chamber that reduces the bag’s inner circumference, combined with a two-piece applier including an advancement measuring indicator and a distal funnel, where pockets engage flexible tentacles or soft curved arms and the bag’s inner portion moves relative to its outer portion during extraction; one independent claim further specifies sliding-range restriction via a chamber and an enlarged proximal portion on the inner tube.
