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

The inventive concept presents an enhanced self-service anastomosis clamp for digestive tract, featuring bio-absorbable outer rings, a flexible outer pipe delivery system, a ratchet mechanism handle, lubricated pulling cables, and serrated inner lancets. These advancements improve tissue grip, reduce tissue inflammation, and enhance deployment precision.

Background and Problem Solved

The original self-service anastomosis clamp for digestive tract, as described in the original patent, had limitations in terms of tissue inflammation, deployment smoothness, and tissue grip. The present inventive concept addresses these limitations by introducing novel materials and mechanisms to enhance the overall performance and safety of the anastomosis clamp.

Detailed Description of the Inventive Concept

The enhanced self-service anastomosis clamp features outer rings made of a bio-absorbable material, reducing tissue inflammation and improving healing. The delivery system is equipped with a flexible outer pipe, allowing for navigation through narrow passages and reducing the risk of tissue damage. The handle is designed with a core bar and slider, incorporating a ratchet mechanism to provide controlled and precise deployment of the clamp. Additionally, the pulling cable is coated with a lubricating material to reduce friction and improve deployment smoothness. The inner lancets are designed with a serrated edge to improve tissue grip and reduce the risk of tissue slippage.

Novelty and Inventive Step

The use of bio-absorbable outer rings, flexible outer pipe delivery system, ratchet mechanism handle, lubricated pulling cables, and serrated inner lancets constitutes a novel and non-obvious improvement over the original patent. These advancements provide a significant enhancement in the performance, safety, and usability of the anastomosis clamp.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include varying the material composition of the outer rings, modifying the design of the flexible outer pipe, or incorporating additional mechanisms to further enhance deployment precision. Variations could also include adapting the anastomosis clamp for use in different medical procedures or applications.

Potential Commercial Applications and Market

The enhanced self-service anastomosis clamp has significant commercial potential in the medical device industry, particularly in the fields of minimally invasive surgery and gastrointestinal procedures. The target market includes hospitals, clinics, and medical research institutions, with potential for widespread adoption and revenue growth.
