A safety isolation bag is a pneumoperitoneum device for intra-abdominal, endoscopic procedures, power morcellation and vaginal morcellation for facilitating safe removal of body mass from within the abdominal cavity. It comprises of an expandable and collapsible enclosed internal space (5) having a neck portion (4) with mouth (3) having retractor means (2) and provided with markings, colour coded indicating how much the bag is to be pulled out for the removal of large, medium and small tissue mass, and also having one or more non-return valves (6) attached with long looped threads (8) on one of the surface in the wall of the safety isolation bag below the neck as a means for introducing the surgical instruments and accessories into the enclosed internal space at the right place and to close the puncture hole after the procedure. It is made of one or more layers of flexible biocompatible/medical grade plastic film.

Tissue retrieval system with retention features

A tissue retrieval system including a tissue retrieval bag deployable from an introducer and suspended in an open configuration by support arms can include retention features to prevent inadvertent movement of the tissue retrieval bag relative to the support arms. The support arms can include protruding domes, folds, or curls to restrict sliding of the tissue retrieval bag relative to the support arms. Alternately, tension can be maintained in a cord loop coupled to an opening of the tissue retrieval bag to prevent the tissue retrieval bag from inadvertently sliding relative to the support arms.

Rollable tissue specimen bag with improved brim for tenting
11707264 · 2023-07-25 · ·

A tissue specimen retrieval bag assembly includes a tissue specimen bag having an open proximal end and a closed distal end, the proximal end including a cuff defined therein and extending therearound. A flexible bag brim is disposed within the cuff and is transitionable between a first, collapsed configuration and a second, expanded configuration. The flexible bag brim includes a cross section configured to facilitate both furling the tissue specimen bag onto itself around the bag brim when the bag brim is disposed in the second, expanded configuration and securing the tissue specimen bag in a desired furled configuration. The flexible bag brim includes a plurality of scallops defined along an inner peripheral surface thereof configured to facilitate furling the tissue specimen bag onto itself.

Apparatus for facilitating access to abdominal cavity of a patient and removing larger cancerous tumors

An apparatus and method is provided for accessing an abdominal cavity of a patient via the anus for any number of surgical operations, e.g., colon cancer, appendectomy, lymph node biopsy, etc. The apparatus includes a tubular body that extends to an open end having a plurality of holes. The tubular body is inserted into the intestine of the patient, and a clamp is inserted through the tubular body of the apparatus and into the intestine. The clamp and the attached intestine is then pulled into the tubular body, so that the intestine can then be cut. The clamp and the adjacent intestine are then moved out of the tubular body so that the surgery may be performed through the intestine. The cut ends of the intestine can then be reattached (e.g., stapled, sutured, etc.) following completion of the surgery.

Systems and methods for tissue removal

Systems and methods for preventing the seeding of cancerous cells during morcellation of a tissue specimen inside a patient's body and removal of the tissue specimen from inside the patient through a minimally-invasive body opening to outside the patient are provided. One system includes a cut-resistant tissue guard removably insertable into a containment bag. The tissue specimen is isolated and contained within the containment bag and the guard is configured to protect the containment bag and surrounding tissue from incidental contact with sharp instrumentation used during morcellation and extraction of the tissue specimen. The guard is adjustable for easy insertion and removal and configured to securely anchor to the body opening. Protection-focused and containment-based systems for tissue removal are provided that enable minimally invasive procedures to be performed safely and efficiently.

Redeploy able tissue retrieval system

A tissue retrieval system including a tissue retrieval bag deployable by an actuator from an introducer and suspended in an open configuration by support arms can be serially redeployed between a partially or fully stowed configuration and a first deployed configuration to be used in procedures to collect multiple samples. The system can include defeasible proximal and distal stop mechanisms to limit movement of the actuator for serial redeployment. The tissue retrieval system can include a retention latch to couple a bead of the tissue retrieval bag to the actuator with the retrieval bag in the first deployed position and a user-selectable deployment release to allow deployment of the retrieval bag to a fully deployed position where it is released from the actuator. A bead stop is positioned to engage the introducer to prevent reintroduction of the bead and bag into the introducer once the bag has been fully deployed.

Laparoscopic workspace device
11690604 · 2023-07-04 · ·

A workspace device including (a) a body having a wall defining an internal volume, collapsible to fit through a laparoscopic passageway in an abdominal wall to an abdominal cavity and expand therein; (b) a first opening defined in said body; (c) a tool channel contiguous with said first opening and extending from said body and configured to remain, at least in part, outside of abdominal wall and sized to receive a laparoscopic tool therein therein; and (d) the body defining an orifice configured to lie in said abdominal cavity when said body is inserted therein, said orifice sized to receive tissue with a minimal cross-sectional area that is twice a minimal cross-sectional area of said first opening, thereby defining a workspace volume to process said tissue in said cavity while said body is not collapsed, using a tool inserted through said first opening.
