Solution Overview

Problem

Current surgical procedures for treating spinal stenosis are highly invasive, requiring large incisions and general anesthesia, leading to significant tissue damage, prolonged recovery times, and increased risk of spinal instability.

Innovation Solution

A percutaneous method using fluoroscopic imaging and anatomical landmarks to access and decompress nerve roots by forming a channel in the lateral recess area of the lamina, employing a device set that includes docking pins and an access portal for precise bone removal without direct visualization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional surgical procedures are used to treat spinal stenosis, then decompression of nerve roots is achieved, but large incisions and general anesthesia are required causing significant tissue damage and prolonged recovery

Engineering Contradiction:

Improvedecompression effectivenessVSAvoidtissue damage

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces traditional open surgical mechanics with percutaneous image-guided mechanics. Instead of large incisions and direct mechanical exposure, the procedure uses fluoroscopic imaging and anatomical landmarks to guide percutaneous access to the lateral recess area, enabling decompression through smaller openings with reduced soft tissue disruption

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces fluoroscopic imaging and anatomical landmarks as intermediaries between the surgeon and the surgical target. These intermediaries enable precise localization and access to the lateral recess area without direct visualization, reducing the need for extensive tissue stripping and muscle detachment

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If traditional surgical procedures are used to treat spinal stenosis, then decompression is achieved, but prolonged recovery time and increased risk of spinal instability occur

Engineering Contradiction:

Improvedecompression effectivenessVSAvoidrecovery time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent substitutes traditional open surgical mechanics with percutaneous image-guided mechanics that preserve spinal stabilizing structures. By avoiding extensive muscle detachment and bone removal, the procedure reduces postoperative pain and accelerates recovery while maintaining decompression effectiveness

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent applies local quality by targeting the specific lateral recess area where nerve root compression occurs, rather than performing extensive global decompression. This localized approach preserves surrounding stabilizing structures and reduces overall tissue damage, leading to faster recovery

Inventive Principle:

Principle #3Local quality

3Object-affected harmful factors

If percutaneous access is used without direct visualization, then tissue damage is minimized, but precise bone removal becomes challenging

Engineering Contradiction:

Improvetissue damageVSAvoidbone removal precision

Core Design Contradiction:

Object-affected harmful factorsVSManufacturing precision

Solution Approach 1:

The patent uses fluoroscopic imaging and anatomical landmarks as intermediaries to achieve precise bone removal without direct visualization. These intermediaries provide real-time guidance for percutaneous access to the lateral recess area, enabling accurate localization and decompression while minimizing soft tissue disruption

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent incorporates fluoroscopic imaging feedback during the percutaneous procedure to guide bone removal. This real-time imaging feedback allows the surgeon to adjust instrument positioning and bone removal depth to achieve precise decompression of the nerve root while preserving surrounding structures

Inventive Principle:

Principle #23Feedback

AI summary

The present disclosure is directed to devices, kits, and methods for treating lumbar spinal stenosis by at least partially decompressing a compressed nerve root. The method can include identifying the compressed nerve root and percutaneously accessing a region of a lamina located adjacent to the compressed nerve root. The method can also include forming a channel through the region of the lamina, wherein the channel can be formed medial to a lateral border of the lamina. Further, the method can include expanding the channel in a lateral direction.
