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. 11,857,431.

Summary of the Inventive Concept

An improved vertebral body replacement system that incorporates real-time monitoring, personalized device selection, and advanced instrumentation to enhance the safety and efficiency of transcorporeal procedures.

Background and Problem Solved

The original patent disclosed a method and apparatus for placement of vertebral body replacement devices into a transcorporeal void during a surgical operation on the cervical portion of the spine. However, the original patent has limitations in terms of device selection, placement accuracy, and bone graft containment. The new inventive concept addresses these limitations by introducing an adjustable-width device, real-time monitoring, and personalized device selection based on pre-operative imaging data.

Detailed Description of the Inventive Concept

The enhanced vertebral body replacement system comprises a vertebral body replacement device with an adjustable width to accommodate varying vertebral body sizes. The system also includes a method for selecting the optimal device width based on pre-operative imaging data. Additionally, the system features real-time monitoring of device placement during the transcorporeal procedure using a sensor-equipped device, providing feedback to the surgeon. Furthermore, the system incorporates an integrated bone graft containment system with a porous structure for bone graft material and a mechanism for securely retaining the bone graft material within the device. A surgical instrument with a tapered drill bit and ergonomic handle is also provided for creating the transcorporeal void. The system enables personalized vertebral body replacement device selection based on patient-specific anatomical data, recommending a device with optimized dimensions and material properties for the individual patient.

Novelty and Inventive Step

The new claims introduce several novel features that distinguish the enhanced vertebral body replacement system from the original patent. The adjustable-width device, real-time monitoring, and personalized device selection based on pre-operative imaging data are non-obvious improvements that address the limitations of the original patent.

Alternative Embodiments and Variations

Alternative embodiments of the enhanced vertebral body replacement system could include variations in device design, such as modular components or alternative materials. The system could also be adapted for use in other spinal regions or for different types of surgical procedures.

Potential Commercial Applications and Market

The enhanced vertebral body replacement system has significant commercial potential in the spinal implant market, which is expected to grow significantly in the coming years. The system's ability to improve safety, efficiency, and patient outcomes could make it an attractive option for surgeons and hospitals.
