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. 11,857,696.

Summary of the Inventive Concept

A novel shield system designed to protect the recurrent laryngeal nerve during neck surgeries in high-altitude, disaster relief, high-humidity, remote, and high-security environments, offering enhanced safety and reliability in these unique operational settings.

Background and Problem Solved

The original patent for a shield for recurrent laryngeal nerve and associated methods addressed the problem of nerve damage during neck surgeries. However, it did not consider the specific challenges posed by specialized environments, such as extreme weather conditions, limited resources, or high-security requirements. The new inventive concept adapts the original shield to these niche scenarios, ensuring the recurrent laryngeal nerve is protected in a broader range of surgical situations.

Detailed Description of the Inventive Concept

The new shield system consists of a lightweight, high-strength biologic material that can withstand extreme pressure and temperature fluctuations, making it suitable for high-altitude neck surgeries. For disaster relief neck surgeries, the shield features a fast-drying, waterproof biologic material that prevents moisture accumulation and bacterial growth. In high-humidity environments, the shield has a water-resistant coating that prevents moisture penetration and a textured surface that enhances grip and handling. For remote or resource-constrained areas, the shield is part of a compact, portable kit with a durable, long-shelf-life biologic material and sterilized, disposable application tools. In high-security environments, the shield is made of a tamper-evident, biologic material that detects and alerts to any unauthorized access or manipulation.

Novelty and Inventive Step

The new claims introduce novel features that address the specific challenges of specialized environments, such as high-altitude, disaster relief, high-humidity, remote, and high-security settings. These features, including the use of lightweight, high-strength biologic materials, fast-drying, waterproof coatings, and tamper-evident materials, provide an inventive step over the original patent by enabling the shield to operate effectively in these unique scenarios.

Alternative Embodiments and Variations

Alternative embodiments of the shield system could include the use of different biologic materials, such as those with enhanced antimicrobial properties or integrated sensors for real-time monitoring. Variations of the shield could also be designed for specific types of neck surgeries, such as thyroid or parathyroid surgeries, or for use in combination with other surgical instruments or devices.

Potential Commercial Applications and Market

The shield system for recurrent laryngeal nerve protection in specialized environments has significant commercial potential in the medical device industry, particularly in the areas of disaster relief, remote healthcare, and high-security medical facilities. The target market includes surgeons, anesthesiologists, and medical professionals working in these unique operational environments.
