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

An advanced surgical stapler buttress system featuring real-time length adjustment, integrated sensors, and customizable modules to optimize tissue compression, minimize bleeding, and improve surgical outcomes.

Background and Problem Solved

The original patent disclosed a surgical stapler buttress with a variable length feature. However, this design had limitations, such as requiring manual trimming and lacking real-time feedback. The new inventive concept addresses these limitations by incorporating sensors, self-adjusting features, and modular designs to create a more efficient, safe, and effective surgical stapler buttress system.

Detailed Description of the Inventive Concept

The enhanced surgical stapler buttress system comprises a variable length feature with an integrated sensor to detect and adjust the length of the buttress in real-time. This sensor enables the system to optimize tissue compression and minimize bleeding. Additionally, the system features a self-adjusting mechanism that dynamically changes the length of the buttress based on the force applied to the tissue. The modular design allows for rapid customization and adaptation to different surgical procedures through interchangeable buttress modules of varying lengths. Furthermore, the system includes an integrated feedback mechanism that provides real-time feedback to the surgeon on the optimal length of the buttress for a specific surgical procedure.

Novelty and Inventive Step

The new inventive concept introduces several novel features, including the integration of sensors, self-adjusting mechanisms, and modular designs, which collectively provide a significant improvement over the original patent. The real-time length adjustment and feedback mechanisms are particularly innovative, as they enable the surgeon to make data-driven decisions during the surgical procedure.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include using different types of sensors, such as optical or ultrasonic sensors, to detect tissue compression. Another variation could involve integrating the buttress system with other surgical instruments, such as endoscopic cameras or force sensors, to provide a more comprehensive surgical platform.

Potential Commercial Applications and Market

The enhanced surgical stapler buttress system has significant commercial potential in the medical device industry, particularly in the areas of minimally invasive surgery, endoscopy, and surgical robotics. The system's ability to optimize tissue compression and minimize bleeding could lead to improved surgical outcomes, reduced post-operative complications, and increased patient satisfaction. The target market includes hospitals, surgical centers, and medical device manufacturers.
