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. 11,857,438.

Summary of the Inventive Concept

A next-generation intervertebral disc prosthesis insertion system utilizing advanced technologies such as neural networks, bio-sensing, micro-robots, and real-time imaging to enable more accurate, efficient, and minimally invasive procedures.

Background and Problem Solved

The original patent addressed the need for improved intervertebral disc prosthesis insertion methods. However, it relied on manual operation and limited visualization. The new inventive concept tackles these limitations by integrating cutting-edge technologies to provide a more autonomous and precise insertion process.

Detailed Description of the Inventive Concept

The system consists of an intervertebral disc prosthesis, an insertion device, and advanced modules such as a neural network-based navigation system, a bio-sensing module, micro-robots, and a real-time imaging module. The insertion device inserts the prosthesis partway into the intervertebral space under constraint, and then releases it. The advanced modules guide the prosthesis into its final position, ensuring optimal placement and minimizing the risk of complications.

Novelty and Inventive Step

The new claims introduce a paradigm shift by incorporating autonomous technologies, enabling a more efficient and accurate insertion process. The use of neural networks, bio-sensing, micro-robots, and real-time imaging represents a significant departure from the original patent's manual operation and limited visualization.

Alternative Embodiments and Variations

Alternative embodiments could include using different types of advanced modules, such as artificial intelligence or computer vision, or integrating the system with other medical devices, like surgical robots. Variations could include adapting the system for use in different types of spinal procedures or developing customized prosthesis designs for specific patient populations.

Potential Commercial Applications and Market

The autonomous intervertebral disc prosthesis insertion system has significant commercial potential in the orthopedic and spine surgery markets, offering improved patient outcomes, reduced recovery times, and increased procedural efficiency. The system could be marketed to hospitals, surgical centers, and orthopedic clinics, with potential for expansion into other medical specialties.
