Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing spinal fusion techniques, particularly posterior lumbar spinal fusion with pedicle screws, are cumbersome, risky, and costly due to the large number of parts and pieces involved, leading to potential construct failure and increased surgical time.

Innovation Solution

An insertion guide assembly with a body having two portions and passageways for guiding screw trajectories, a plate holder, and a docking pin to secure a plate to the anatomical structure, allowing for precise placement of fixation elements to establish bone fusion systems.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional pedicle screw fusion systems are used, then spinal stabilization can be achieved, but the large number of parts increases device complexity and surgical risk

Engineering Contradiction:

Improvespinal stabilization reliabilityVSAvoidnumber of parts

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple separate components (plate, screws, rods, connectors) into an integrated spinal fixation system where the plate serves as the primary structural element with built-in screw holes and attachment points, reducing the number of discrete parts while maintaining stabilization reliability

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The plate design incorporates multiple functions: it provides structural support, guides screw placement through pre-drilled holes, serves as an attachment point for rods, and enables angular adjustments, replacing the need for multiple specialized components

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If traditional pedicle screw fusion techniques are used, then spinal fusion can be achieved, but surgical time increases due to the large number of parts

Engineering Contradiction:

Improvespinal fusion outcomeVSAvoidsurgical time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The plate is pre-configured with precisely positioned screw holes and attachment points during manufacturing, eliminating the need for intraoperative measurement and positioning of multiple components, thus reducing surgical time while ensuring accurate placement for successful fusion

Inventive Principle:

Principle #10Preliminary action

3Reliability

If traditional pedicle screw fusion systems are used, then spinal stabilization is achieved, but the risk of construct failure increases

Engineering Contradiction:

Improvespinal stabilizationVSAvoidconstruct failure risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

By integrating multiple fixation functions into a single plate structure with built-in screw holes and rod attachments, the system eliminates interfaces between separate components that could fail, reducing the overall risk of construct failure while maintaining spinal stabilization

Inventive Principle:

Principle #5Merging (Combining)

AI summary

Implant systems in some embodiments such as midline incision implant systems may generally include an insertion guide assembly and a plate, which define fixation trajectories. In other embodiments such as a percutaneous implant system may generally include a first a plate, an insertion guide, and a separate second insertion guide, which define fixation trajectories. Surgical methods include use of the implant systems with the plates, and use of plates alone, for installing bone fusion systems.
