This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,190.

Summary of the Inventive Concept

A next-generation surgical stapler system featuring a modular buttress assembly with interchangeable length modules, real-time length adjustment, and advanced data analytics to optimize surgical outcomes.

Background and Problem Solved

The original surgical stapler buttress with variable length feature, disclosed in the original patent, has limitations in terms of flexibility, adjustability, and data integration. The new inventive concept addresses these limitations by introducing a modular design, real-time length adjustment, and advanced data analytics to improve surgical outcomes and reduce complications.

Detailed Description of the Inventive Concept

The modular buttress assembly consists of interchangeable length modules, each with a unique identifier for automated tracking and inventory management. The system includes a sensor-equipped buttress assembly and a control unit that receives feedback from the sensor and adjusts the buttress length in real-time during a surgical procedure. The system also features a computer-implemented predictive analytics module that uses machine learning algorithms and a database of historical surgical data to predict optimal buttress lengths for various surgical procedures. Additionally, the system includes a networked surgical platform that enables real-time data exchange and collaboration between surgeons during a surgical procedure.

Novelty and Inventive Step

The new inventive concept introduces a paradigm shift in surgical stapler technology by integrating modular design, real-time length adjustment, and advanced data analytics. The unique combination of these features provides a significant improvement over the original patent, enabling more precise and effective surgical procedures.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include variations in the modular design, such as using different materials or geometries for the length modules. Additionally, the system could be adapted for use in other surgical procedures or medical specialties, such as orthopedic or cardiovascular surgery.

Potential Commercial Applications and Market

The modular buttress assembly for surgical staplers with real-time length adjustment has significant commercial potential in the medical device industry, particularly in the areas of minimally invasive surgery and surgical robotics. The target market includes hospitals, surgical centers, and medical device manufacturers.
