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. 11,857,220.

Summary of the Inventive Concept

The present inventive concept relates to specialized protective devices for use during surgery in unique operational environments, such as high-security needs, disaster relief, extreme weather conditions, high-altitude environments, and high-humidity environments. These devices address specific challenges and limitations associated with traditional protective devices in these contexts.

Background and Problem Solved

The original patent disclosed a protective device for use during laparoscopic surgery. However, this device may not be suitable for use in specialized environments, such as high-security needs, disaster relief, extreme weather conditions, high-altitude environments, and high-humidity environments. The new inventive concept addresses the limitations of the original patent by providing protective devices tailored to these unique operational environments, ensuring enhanced safety and efficacy during surgical procedures.

Detailed Description of the Inventive Concept

The new inventive concept comprises a series of specialized protective devices, each designed to address specific challenges associated with unique operational environments. For instance, the device for high-security environments features an expandable body made of a high-security material resistant to energy and/or contact burns from a surgical tool, and an inner member designed to thermally insulate the tissue to be protected. The device for extreme weather conditions features a weather-resistant material, ensuring the protective device maintains a substantially planar orientation during use. The device for disaster relief scenarios features an expandable body with a layer of silicone over-molded onto an inner member, which compresses or folds the protective device into an insertion condition, providing resistance to energy and/or contact burns from a surgical tool. Similarly, the devices for high-altitude environments and high-humidity environments feature lightweight materials and thermal insulation, respectively, to address the specific challenges associated with these environments.

Novelty and Inventive Step

The new inventive concept's novelty lies in its adaptation of the original protective device to address specific challenges associated with unique operational environments. The inventive step is the provision of specialized materials, designs, and features tailored to each environment, ensuring enhanced safety and efficacy during surgical procedures. These adaptations are non-obvious and unexpected, as they require a deep understanding of the specific challenges and limitations associated with each environment.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include the use of different materials, designs, or features tailored to specific environments. For example, the device for high-security environments could feature an additional layer of protection, such as a metal mesh, to enhance its resistance to energy and/or contact burns. The device for extreme weather conditions could feature a reinforced structure to withstand harsh environmental conditions. These alternative embodiments and variations ensure broad conceptual coverage and facilitate further innovation in this area.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in the medical device industry, particularly in the areas of laparoscopic surgery, disaster relief, and specialized surgical environments. The market for these devices is substantial, driven by the growing demand for minimally invasive surgical procedures and the need for enhanced safety and efficacy in unique operational environments. Potential customers include hospitals, medical research institutions, and disaster relief organizations.
