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. 11,857,192.

Summary of the Inventive Concept

An improved anastomosis clamp delivery system with enhanced visualization, reduced friction, and increased cost-effectiveness, providing a more efficient and reliable solution for digestive tract surgery.

Background and Problem Solved

The original self-service anastomosis clamp delivery system, while effective, has limitations in terms of visualization, deployment ease, and cost. The new inventive concept addresses these limitations by introducing a built-in LED light source, hydrophilic-coated pulling cable, detachable thrust ring, adjustable transparent cap diameter, and sensor-equipped handle.

Detailed Description of the Inventive Concept

The enhanced delivery system features a flexible middle sheath with an integrated LED light source, providing surgeons with improved visualization during deployment. The pulling cable is coated with a hydrophilic material, reducing friction and facilitating smoother deployment. The thrust ring is designed to be detachable and reusable, minimizing waste and improving cost-effectiveness. The transparent cap is engineered with an adjustable diameter to accommodate varying sizes of digestive tracts. The handle is equipped with sensors to monitor and provide real-time feedback on the deployment process, ensuring precise control and optimal results.

Novelty and Inventive Step

The new inventive concept introduces a unique combination of features that significantly improve the performance, efficiency, and cost-effectiveness of the original anastomosis clamp delivery system. The built-in LED light source, hydrophilic-coated pulling cable, detachable thrust ring, adjustable transparent cap diameter, and sensor-equipped handle provide a non-obvious solution to the limitations of the original patent.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include variations in the LED light source, such as adjustable intensity or color, or alternative materials for the hydrophilic coating. The detachable thrust ring could be designed with different geometries or materials to accommodate specific surgical procedures. The adjustable transparent cap diameter could be achieved through different mechanical or hydraulic mechanisms.

Potential Commercial Applications and Market

The enhanced anastomosis clamp delivery system has significant commercial potential in the medical device industry, particularly in the fields of digestive tract surgery and minimally invasive procedures. The improved performance, efficiency, and cost-effectiveness of the system make it an attractive solution for hospitals, clinics, and surgical centers worldwide.
