Adjustable Intervertebral Implant Armatures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical implants for spinal fusion procedures are often designed for a single approach, compromising key features necessary for successful placement and stability, and prior art expandable implants fail to accommodate minimally invasive portal insertion and anatomical variations, leading to misalignment and inefficiency.
Innovation Solution
A surgical device with adjustable features, including a first module with a bore and a sliding armature, allowing for configuration changes post-insertion, and patient-specific surfaces for precise anatomical fit, enabling efficient distraction and stabilization of adjacent vertebrae through various surgical approaches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single-configuration implant is used for minimally invasive portal insertion, then the device can be delivered through small incisions, but the implant cannot be adjusted to accommodate anatomical variations and may result in misalignment
Solution Approach 1:
The implant incorporates adjustable armatures that can be repositioned after insertion through a minimally invasive portal. The armatures are designed to be manipulated from outside the body to adjust the implant's configuration, allowing it to adapt to anatomical variations while maintaining the benefits of minimally invasive delivery.
Solution Approach 2:
The implant is divided into modular components including a body and multiple adjustable armatures. This segmentation allows each armature to be independently positioned and adjusted to match the patient's specific anatomy, while the main body remains fixed after insertion.
2Ease of manufacture
If the implant is designed for ease of insertion, then the surgical procedure is simplified, but the implant's ability to provide adequate support and stability is compromised
Solution Approach 1:
The implant transitions from a static design to a dynamic, adjustable structure. After easy insertion, the armatures can be adjusted and locked into position to provide optimal support and stability tailored to the patient's anatomy, ensuring both ease of insertion and long-term reliability.
Solution Approach 2:
The implant's structural parameters can be changed after insertion by adjusting the armature positions. This allows the implant to be optimized for support and stability based on the actual anatomical conditions encountered during surgery, while maintaining the simplicity of initial insertion.
3Device complexity
If a fixed-configuration implant is used, then the device structure is simple, but the implant cannot be quickly manipulated to conform to patient-specific anatomical features
Solution Approach 1:
The implant is segmented into a main body and multiple independent armatures that can be quickly adjusted. This modular design allows for rapid reconfiguration without requiring complex mechanisms, balancing structural simplicity with adjustment speed to match anatomical variations efficiently.
Solution Approach 2:
The implant incorporates dynamic adjustment capabilities where armatures can be quickly repositioned from outside the body. The design allows for fast manipulation and locking of armatures into desired positions, enabling the implant to conform to patient-specific anatomy without significantly increasing device complexity or surgical time.

AI summary
The present disclosure relates to a surgical device, such as a surgical implant, which may be used in several types of procedures. More specifically, the present disclosure relates to implants for use in an anterior, posterior, posterior lateral or direct lateral approach to the disc space. The surgical device may be manipulated in various manners to accommodate delivery through a minimally invasive portal in one configuration and adjusted to a second configuration once placed in the intervertebral space. A delivery system for placing the surgical device in a body is also disclosed.
