Legal Citation
Summary of the Inventive Concept
The present inventive concept discloses improved systems and methods for large tissue specimen removal from internal body cavities, addressing the limitations of existing containment bag systems by incorporating reinforced materials, adjustable volumes, integrated tissue morcellation devices, and built-in suction systems.
Background and Problem Solved
The original patent for 'Systems and methods for large tissue specimen removal' has limitations in terms of containment bag strength, tissue size accommodation, and fluid removal efficiency. The new inventive concept addresses these limitations by introducing novel features that enhance the overall removal process, making it safer, faster, and more efficient.
Detailed Description of the Inventive Concept
The inventive concept comprises a containment bag with a reinforced material layer for enhanced strength and durability during tissue breakdown and removal. Additionally, the system features an adjustable containment bag volume to accommodate varying tissue sizes, ensuring efficient removal. Furthermore, an integrated tissue morcellation device is incorporated into the access cannula, facilitating efficient tissue breakdown. The containment bag also includes a built-in suction system for efficient fluid removal and reduced surgical site contamination. The system's real-time tissue fragmentation monitoring system optimizes tissue removal efficiency and safety.
Novelty and Inventive Step
The new inventive concept's novelty lies in the combination of reinforced containment bag materials, adjustable volumes, integrated tissue morcellation devices, built-in suction systems, and real-time tissue fragmentation monitoring. These features collectively provide a significant improvement over existing systems, making the inventive concept non-obvious and novel.
Alternative Embodiments and Variations
Alternative embodiments of the inventive concept may include variations in containment bag materials, adjustable volume mechanisms, and tissue morcellation device designs. Additionally, the system could be adapted for use in different surgical procedures or body cavities, ensuring broad conceptual coverage.
Potential Commercial Applications and Market
The enhanced systems and methods for large tissue specimen removal have significant commercial potential in the medical device industry, particularly in the fields of laparoscopic and endoscopic surgery. The target market includes hospitals, surgical centers, and medical device manufacturers seeking to improve surgical efficiency, safety, and patient outcomes.
