Anterior Cervical Distractor Centering and Distraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical methods for correcting cervical spinal deformities lack effective tools for precise distraction and centering of vertebral bodies, leading to inefficiencies in maintaining proper disc space and alignment during anterior cervical surgeries.
Innovation Solution
The Anterior Cervical Distractor System, comprising a distractor assembly with adjustable distraction members and a centering assembly, allows for controlled separation and alignment of vertebral bodies, utilizing a combination of distraction plates and expansion members to maintain disc space and centering against the Uncinate Process, facilitating precise surgical interventions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional surgical methods are used for correcting cervical spinal deformities, then surgical procedures can be performed, but precise distraction and centering of vertebral bodies cannot be achieved
Solution Approach 1:
The distractor device is divided into distinct functional segments: a distractor assembly with distraction members for separating vertebral bodies, and a centering assembly with positioning members for aligning the device against the Uncinate Process. This segmentation allows each component to perform its specific function independently, achieving precise distraction and centering separately while maintaining overall surgical efficiency.
Solution Approach 2:
The centering assembly with positioning members is designed to establish proper alignment and centering of the distractor device against the Uncinate Process before the distraction function is activated. This preliminary centering action ensures that subsequent distraction forces are applied along the correct axis, maintaining proper disc space and alignment throughout the surgical procedure.
2Object-affected harmful factors
If disc removal is performed to alleviate pain from intervertebral separation reduction, then pain relief can be achieved, but maintaining natural separation distance becomes difficult
Solution Approach 1:
The distractor device is inserted and centered against the Uncinate Process before disc removal to establish and maintain the natural separation distance between vertebral bodies. This preliminary positioning ensures that when the disc is removed, the vertebral bodies remain properly spaced, preventing the buckling and anular tears that cause pain while allowing for effective discectomy.
Solution Approach 2:
The distractor device acts as an intermediary tool that temporarily maintains the natural separation distance between vertebral bodies during surgery. By providing mechanical support and spacing, it allows surgeons to remove damaged discs while preserving the critical intervertebral separation, preventing the harmful effects of vertebral body collapse and anular disruption.
