The innovation of minimally invasive technology has made laparoscopic surgery the mainstream choice in modern medicine. However, how to safely remove diseased tissues in a narrow operating space remains a challenge for surgeons. The Retrieval Bag, as a solution to laparoscopic surgery, achieves a dual balance of "aseptic isolation" and "minimally invasive operation" through precise design. This article will deeply analyze "What is the bag used for in laparoscopic surgery?" and reveal the core value of this instrument in clinical practice.

Three Core Functions of the Retrieval Bag

The Retrieval Bag is a sealed storage tool specifically designed for laparoscopic surgery , and its core application scenarios cover the following aspects:

1. Preventing Intraoperative Contamination and Tumor Dissemination

Isolating the Source of Infection: In surgeries such as ovarian cysts and teratomas, the Retrieval Bag can completely enclose the diseased tissues, avoiding the leakage of cyst fluid or toxic substances into the abdominal cavity. For example, when using a harmonic scalpel to cut cysts, the operation inside the bag can block the splashing of tissue debris and reduce the risk of postoperative infection.

Blocking Malignant Dissemination: For specimens that may hide malignant tumors (such as uterine fibroids), the standardized Specimen Pouch, with its high-strength TPU material and spiral pull wire sealing structure, ensures that the crushing operation is carried out in a completely closed space, preventing the dissemination of tumor cells.

2. Protecting the Function of Healthy Tissues and Organs

Reducing Mechanical Damage: Through techniques such as cold knife cutting and manual suturing inside the bag, it can reduce the traction and stimulation of sensitive organs such as the pregnant uterus and ovaries. For example, during surgery in pregnancy, placing the ovary in the Endocatch Bag and pulling it to the umbilicus for fixation can significantly reduce the pressure on the uterus.

Optimizing the Surgical Field of View: The transparent bag design allows doctors to observe the operation area in real-time. At the same time, the nitinol stent automatically expands the bag mouth, avoiding tissue friction caused by repeated entry and exit of instruments.

3. Improving Operational Efficiency and Safety

One-handed Quick Deployment: The standardized Specimen Pouch is usually equipped with a push-pull handle. Doctors can expand the bag in the abdominal cavity by pushing the inner sleeve rod, greatly shortening the operation time.

Adaptive Retrieval Solutions: For large specimens (such as a 25cm parasitic myoma), they can be crushed in the bag or removed through the vagina without expanding the incision.

Technological Evolution: From "Handmade" to "Professional Design"

The technological iteration of the Retrieval Bag is mainly reflected in the dual breakthroughs of materials and functions:

1. Material Upgrade: Emphasizing Safety and Durability

Medical-grade TPU Film: Replacing early surgical gloves or plastic films, it has the characteristics of tear resistance and leakage prevention and can withstand the high-frequency vibration of a harmonic scalpel.

Intelligent Auxiliary Structure: Some high-end Endocatch Bags are equipped with a silicone edge reinforcement layer to prevent sharp objects from cutting through. The airway design facilitates inflating and expanding the bag during the operation.

2. Functional Segmentation: Scenario-based Solutions

The Suspension System of the Endocatch Bag: The bag is fixed by pre-implanted sutures penetrating the abdominal wall, avoiding the leakage of cyst fluid caused by intraoperative displacement, especially suitable for large ovarian masses.

Capacity Grading of the Specimen Pouch: In gynecological surgeries, small bags with a capacity of 200-500ml are commonly used, while in urological surgeries, specifications above 800ml are required to accommodate specimens of the bladder or intestine.

Key Strategies in Clinical Applications

When choosing a suitable Retrieval Bag according to the type of surgery, the following factors need to be comprehensively considered:

1. The Refined Needs of Gynecological Surgeries

Ovarian Surgery During Pregnancy: It is preferable to choose a bag with cold knife cutting and manual suturing to avoid the impact of heat on the fetus. It is necessary to pull and fix it through the umbilicus to reduce the pressure on the uterus.

Resection of Malignant Tumors: It is essential to use the Endocatch Bag with the highest leakage prevention level and complete the crushing inside the bag, strictly following the tumor-free principle.

2. Special Scenarios in General Surgery and Urology

Emergency Foreign Body Removal: It is recommended to use a Specimen Pouch with a puncture protection layer to prevent metal fragments from cutting through the bag.

Lymph Node Dissection: In radical cystectomy, the completely resected lymphatic tissues need to be immediately placed in the Retrieval Bag to avoid metastasis caused by contact with the abdominal cavity.

Future Trends: Intelligence and Sustainable Development

With the popularization of laparoscopic robot technology, the Retrieval Bag is making breakthroughs in two major directions:

Intelligent Monitoring Function: Some studies attempt to add fluorescent markers or pH-sensitive coatings to the bag to provide real-time early warnings of leakage risks.

Application of Environmentally Friendly Materials: The research and development of degradable biofilms and reusable disinfected bags are expected to reduce the burden of medical waste.

Conclusion

The Retrieval Bag is not only a "safe container" for laparoscopic surgery but also a key guarantee for the safety of minimally invasive technology in oncology. From isolating the source of infection to protecting pregnant organs, its value has gone beyond the simple function of the instrument and has become an indispensable part of the standardized process of modern surgery. Understanding its technical principles and scenario-based application strategies will help doctors find the best balance between "minimally invasive" and "safe".
