Lordotic Spinal Implant Straight Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spinal implants for lumbar or sacral surgeries often require rotation during implantation, increasing the risk of surgical errors and complicating the insertion process.
Innovation Solution
A biocompatible spinal implant with a unique aperture bordered by twelve erect edges, including six straight edges and a curved edge between each straight edge, allowing for direct straight insertion and creating a lordotic angle for oblique trajectory, eliminating the need for rotation and enabling insertion without specialized devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If prior art implants are used for lumbar or lumbar/sacral surgeries, then the implant can be implanted into the surgically created cavity, but rotation is required during implantation which increases the risk of surgical errors
Solution Approach 1:
The implant features an asymmetric lordotic angle (e.g., 20 degrees) that is built into the structure itself. This asymmetric geometry allows the implant to be inserted directly along the oblique trajectory of the surgical cavity without requiring rotation, thereby eliminating the risk of rotational errors while maintaining proper anatomical alignment
Solution Approach 2:
The implant incorporates a three-dimensional lordotic angle that addresses the oblique nature of the surgical cavity. By designing the implant with this angular dimension built-in, the patent transforms the insertion process from a two-step operation (insertion plus rotation) into a single straight-line insertion, improving reliability
2Ease of operation
If prior art implants are used for lumbar or lumbar/sacral surgeries, then the implant can be implanted into the surgically created cavity, but the insertion process is complicated requiring turning maneuvers
Solution Approach 1:
The built-in lordotic angle creates an asymmetric shape that matches the oblique surgical cavity trajectory. This allows the implant to be inserted in a single straight motion without complicated turning maneuvers, simplifying the surgical procedure while maintaining proper anatomical alignment
Solution Approach 2:
By incorporating the lordotic angle as a fundamental geometric dimension of the implant, the patent enables direct insertion along the oblique trajectory. This eliminates the need for post-insertion rotation or complex maneuvering, reducing surgical complexity
3Ease of manufacture
If prior art implants are used for lumbar or lumbar/sacral surgeries, then the implant can be implanted into the surgically created cavity, but specially manufactured insertion devices are required
Solution Approach 1:
The implant's built-in lordotic angle enables it to self-align with the oblique surgical cavity during direct insertion. This self-aligning geometry eliminates the need for specially manufactured insertion devices with complex mechanisms, allowing use of simpler, more readily available surgical tools
