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. 11,857,186.

Summary of the Inventive Concept

An improved surgical fastener applier that incorporates a self-contained power source, integrated sensors, and detachable power packs to enhance efficiency, safety, and ease of use in various surgical procedures.

Background and Problem Solved

The original patent disclosed a surgical fastener applier with a loading unit that required manual actuation, which can be time-consuming and may lead to user fatigue. The new inventive concept addresses these limitations by introducing a self-contained power source, integrated sensors, and detachable power packs, enabling faster and more efficient surgical procedures while reducing the risk of infection and improving user experience.

Detailed Description of the Inventive Concept

The enhanced surgical fastener applier comprises a housing with a proximal opening, an elongated shaft with a lumen to receive a loading unit, and a loading unit with a self-contained power source for actuating surgical fasteners. The loading unit may also include integrated sensors to detect the type of surgical fasteners and adjust the firing force accordingly. Additionally, the loading unit may have a detachable and rechargeable power pack for extended usage. A built-in sterilization mechanism can be incorporated to reduce the risk of infection. The applier can be loaded using a method that involves inserting the loading unit, engaging it with an actuator, and actuating the loading unit using the self-contained power source.

Novelty and Inventive Step

The new claims introduce a self-contained power source, integrated sensors, detachable power packs, and a built-in sterilization mechanism, which are not present in the original patent. These features provide a significant improvement in efficiency, safety, and ease of use, making the new inventive concept novel and non-obvious compared to the original patent.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept may include varying the design of the loading unit, using different types of power sources or sensors, or incorporating additional features such as real-time feedback or data analytics. Variations of the method for loading the applier may include using different engagement structures or actuation mechanisms.

Potential Commercial Applications and Market

The enhanced surgical fastener applier has significant commercial potential in the medical device industry, particularly in the fields of general surgery, laparoscopic surgery, and robotic-assisted surgery. The target market includes hospitals, surgical centers, and medical device manufacturers.
