Solution Overview

Problem

Current methods for stabilizing the vertebral column and introducing an intervertebral disk prosthesis often require multiple components and significant soft tissue trauma, leading to invasive procedures with prolonged recovery times.

Innovation Solution

A process that stabilizes adjacent vertebral bodies using a single stabilizing element, such as a bone screw, which passes through each vertebral body in the longitudinal direction, allowing for direct connection and minimally invasive insertion through a single access point, and an intervertebral disk prosthesis introduced laterally via an extraforaminal access point to minimize tissue damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a rod system with multiple pedicle screws is used to stabilize the vertebral column, then reliable stabilization is achieved, but soft tissue trauma increases and device complexity increases

Engineering Contradiction:

Improvevertebral column stabilizationVSAvoidsoft tissue trauma

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent combines multiple stabilization functions into a single stabilizing element that replaces the traditional rod system with multiple pedicle screws. This single element performs both anchoring and connecting functions, reducing the number of components and minimizing soft tissue trauma while maintaining stabilization reliability.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The stabilizing element is designed with multi-functionality, serving as both an anchoring device and a connecting structure. It can be introduced through a single access point and provides both fixation and stabilization functions that previously required separate components, thereby reducing trauma and complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If multiple components are used for vertebral stabilization, then reliable connection is achieved, but device complexity and number of components increase

Engineering Contradiction:

Improvevertebral bodies connectionVSAvoidnumber of components

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges multiple stabilization components into a single integrally designed stabilizing element. This element combines the functions of pedicle screws and connecting rods, reducing the total number of components while ensuring reliable connection between vertebral bodies through its multi-functional design.

Inventive Principle:

Principle #5Merging (Combining)

3Ease of operation

If traditional access points are used for introducing stabilization components, then adequate access is achieved, but soft tissue trauma increases

Engineering Contradiction:

Improveaccess to vertebral bodiesVSAvoidsoft tissue trauma

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the stabilization function from multiple traditional access points and consolidates it into a single access point. The stabilizing element is designed to be introduced through this single point, eliminating the need for multiple incisions and reducing soft tissue trauma while maintaining adequate access to the vertebral bodies.

Inventive Principle:
