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. 11,857,377.

Summary of the Inventive Concept

An improved ingress-egress apparatus and related methods for enhanced protection of surgical work sites during removal of surgical implants, featuring novel design elements and integrated functionalities to increase efficiency, safety, and sterility.

Background and Problem Solved

The original ingress-egress apparatus, while effective, had limitations in terms of metal particle removal, temperature control, and risk of cross-contamination. The new inventive concept addresses these limitations by introducing a tapered frustum surface with a spiral-shaped sidewall, integrated temperature control, detachable and sterilizable base components, and vacuum-assisted egress ports.

Detailed Description of the Inventive Concept

The enhanced ingress-egress apparatus features a modified frustum surface with a spiral-shaped sidewall to enhance vortex formation and metal particle removal. An integrated temperature control unit maintains a predetermined temperature range during the surgical procedure. The apparatus also includes an antimicrobial coating to reduce the risk of post-surgical infection. Additionally, the device features a detachable, disposable, and sterilizable base component to minimize the risk of cross-contamination, and a vacuum-assisted egress port to facilitate efficient removal of metal particles and irrigating fluid. The apparatus can be used in conjunction with a sterile saline solution delivery system, comprising a pressurized fluid reservoir, a flow control valve, and a sterile fluid pathway to ensure consistent and controlled delivery of irrigating fluid during surgical procedures.

Novelty and Inventive Step

The new inventive concept introduces several novel elements, including the spiral-shaped sidewall, integrated temperature control, detachable and sterilizable base components, and vacuum-assisted egress ports, which provide a significant improvement over the original patent. These features, in combination, enable more efficient and safe removal of surgical implants, reducing the risk of post-surgical infection and improving overall surgical outcomes.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include variations in the spiral-shaped sidewall design, different materials and coatings for the apparatus, and integration with other surgical instruments or systems. Additionally, the apparatus could be adapted for use in various surgical specialties, such as orthopedic, neurosurgical, or cardiovascular procedures.

Potential Commercial Applications and Market

The enhanced ingress-egress apparatus has significant commercial potential in the surgical instrument market, particularly in the areas of orthopedic and neurosurgical procedures. The device's ability to improve surgical outcomes, reduce the risk of post-surgical infection, and increase efficiency could lead to widespread adoption in hospitals and surgical centers worldwide.
