This comprehensive sizing matrix ensures the right bag is available for every procedure, reducing the need for improvisation or multiple bag insertions.
Tie-Rod and Pull-Rope Configurations – The system offers two distinct closure mechanisms: tie-rod bags that provide secure closure through a pull mechanism, and pull-rope bags that offer rapid, one-handed closure. Both configurations are available in all sizes, allowing surgeons to choose the closure method that best suits their surgical technique and anatomical access.
5 mm Puncture Compatibility – The unique metal tube retrieval bag design allows passage through a 5 mm puncture device, making it suitable for ultra-minimally invasive approaches. This feature significantly reduces the size of the access incision required for specimen removal, minimizing tissue trauma and improving cosmetic outcomes.
Minimizes Contamination Risk – The retrieval bag effectively contains specimens during removal, preventing contamination of other tissues, organs, or the abdominal wall. This is particularly important in oncological procedures where tumor spillage must be avoided, as well as in cases of infected or inflamed tissues where contamination could lead to postoperative complications.
Single-Use Sterile Design – Supplied sterile and intended for single use, the retrieval bag eliminates the risk of cross-contamination and ensures optimal performance with every procedure. The bag is individually packaged and ready to use, simplifying OR preparation and reducing the risk of sterile field compromise.
Effective for Multiple Specimen Types – The bag is suitable for containing both solid and semi-solid specimens, including gallbladder, appendix, kidney, spleen, uterine fibroids, ovarian cysts, and lung nodules. The robust film construction resists tearing even when containing sharp or irregular specimens, ensuring secure containment throughout the extraction process.

RFQ – Request for Quotation
Q1: What is the difference between the tie-rod and pull-rope closure mechanisms, and when should each be used?
A: The tie-rod configuration (ZQWA series) features a rigid rod that maintains the bag opening during placement and is drawn closed using a pull mechanism, providing secure closure suitable for larger or heavier specimens. The pull-rope configuration (ZQWB series) offers a flexible rope that is drawn closed for one-handed containment, which is particularly convenient in tight surgical fields or when rapid closure is desired. Both configurations are available in all sizes, and the choice should be based on surgeon preference and the specific anatomical access. The tie-rod design generally provides more control during placement, while the pull-rope design offers greater flexibility in confined spaces.
Q2: What is the maximum specimen size that can be accommodated by the largest retrieval bag?
A: The 130 mm diameter bag (ZQWA-130 and ZQWB-130) can accommodate specimens up to approximately 130 mm in diameter, which is suitable for most kidney, spleen, and large uterine specimens. The bag opening size is the limiting factor, but the bag material is flexible and can conform to the shape of the specimen, accommodating specimens that exceed the nominal diameter in one dimension. For large specimens, the bag can be used in conjunction with a morcellator or opened through a slightly larger extraction incision.
Q3: Can the retrieval bag be used through a 5 mm port?
A: Yes, the unique metal tube retrieval bag design allows passage through a 5 mm puncture device, making it suitable for ultra-minimally invasive approaches. This feature is particularly valuable in procedures where minimizing port size is a priority, such as in pediatric surgery, cosmetic-conscious patients, or in areas with limited access. The 5 mm compatibility significantly reduces the size of the access incision required for specimen removal, minimizing tissue trauma and improving cosmetic outcomes. The metal tube design ensures that the bag can be delivered through the small port without collapsing or damaging the bag.
Q4: What is the recommended technique for placing the retrieval bag, and are there any special considerations?
A: The recommended technique involves inserting the retrieval bag through an appropriate trocar or incision (10 mm or 12 mm, or 5 mm for the metal tube version). The push-handle is then advanced to automatically unfold the bag opening. The specimen is placed into the bag using a grasper, ensuring complete containment. The bag is then closed using the tie-rod or pull-rope mechanism, and the bag is gently extracted through the port or incision. Special considerations include avoiding overfilling the bag, which may lead to tearing during extraction, and ensuring that the bag is not placed against sharp instruments or trocar edges that could damage the film. For larger specimens, we recommend extending the incision slightly to avoid excessive force during extraction.
Q5: Are there any specific contraindications or precautions for using the retrieval bag?
A: The retrieval bag is contraindicated for use in patients with known allergies to the bag materials (polyethylene or polyurethane). It should not be used if the sterile packaging is damaged or compromised. Precautions include avoiding contact with sharp instruments that could puncture the bag, ensuring that the bag opening is fully unfolded before placing the specimen to avoid losing the specimen, and avoiding excessive force during extraction that could cause bag rupture. For infected or inflamed specimens, we recommend using a larger bag size to ensure complete containment and minimize the risk of contamination.
Q6: What is the standard shelf life and storage condition for the retrieval bags?
A: The Disposable Retrieval Bags have a typical shelf life of 3–5 years from the date of manufacture, as indicated on the product labeling. They should be stored in a cool, dry environment away from direct sunlight and extreme temperatures. The sterile packaging should remain intact until the time of use to ensure sterility. We recommend checking the expiration date before use and disposing of any expired or damaged products.
