Abstract
A tissue specimen removal device comprises a specimen bag; a flexible ring, the flexible ring configured to form a top opening of the specimen bag; a cannula assembly comprising: an inner tube portion and an outer tube portion. The device may further comprise a connector carrier, the connector carrier configured to retain at least one connector housing, the at least one connector housing comprising one or more connector portions and reside within an interior of the connector carrier, and wherein the connector carrier can be moved from a position within the cannula assembly to outside the cannula assembly.
Core Innovation
The invention provides a minimally invasive tissue specimen removal device that includes a specimen bag and a cannula assembly. The specimen bag comprises one or more tissue segmentation device components and includes a top opening formed by a flexible ring.
The cannula assembly includes an inner tube handle portion and an outer tube portion. The cannula assembly further includes at least one connector housing having one or more connector pins, and a connector carrier configured to retain the connector housing, where the connector housing resides in an interior of the connector carrier and the connector carrier resides within an interior of the cannula assembly.
The connector carrier can be moved from a position within the cannula assembly to outside the cannula assembly. The at least one connector housing is removable from the connector carrier prior to or during tissue segmentation, and connector pins are configured to be pulled out of the connector housing prior to or during tissue segmentation.
Claims Coverage
The independent claims cover three main inventive features centered on the specimen bag, the cannula assembly, and staged handling of connector housings and pins.
Specimen bag with flexible-ring top opening
A specimen bag comprising one or more tissue segmentation device components and a flexible ring configured to form a top opening of the specimen bag.
Cannula assembly with inner and outer tube portions and connector carrier
A cannula assembly comprising an inner tube handle portion and an outer tube portion, with a connector carrier residing within an interior of the cannula assembly and retaining at least one connector housing having one or more connector pins.
Staged exteriorization and removal of connector housings or pins
The connector carrier is moved from a position within the cannula assembly to outside the cannula assembly, and the at least one connector housing is removable from the connector carrier prior to or during tissue segmentation, including configurations where connector pins are configured to be pulled out of the connector housing prior to or during tissue segmentation.
The claims jointly cover a tissue specimen removal device that integrates a specimen bag having a flexible-ring top opening with a cannula assembly that houses a connector carrier, and require staged movement of the connector carrier with removal or pull-out of connector housings or pins prior to or during tissue segmentation.
