Surgical Adaptor Angulation Module Spinal Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical methods for correcting spinal disorders, such as degenerative disc disease and kyphosis, face challenges in efficiently manipulating vertebral tissue for precise alignment and stabilization, particularly in achieving desired angles and maintaining corrections during procedures like ligamentotaxy and interbody fusion.
Innovation Solution
A surgical system comprising a surgical adaptor with an arm and expandable sleeve that engages with a fastener and surgical instrument, allowing for adjustable angulation and manipulation of vertebral tissue, including a compressor/distractor mechanism for parallel distraction or compression, and an angulation module for precise vertebral angle correction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional spinal implants are used for vertebral manipulation, then basic stabilization is achieved, but precise alignment and angulation control are insufficient
Solution Approach 1:
The adaptor serves as an intermediary component between the implant support and surgical instruments. It includes an arm with a longitudinal member engageable with the implant support and a transverse member with a recess for the spinal rod, enabling precise angular adjustment and transmission of manipulation forces to the vertebral tissue while maintaining stable connection
Solution Approach 2:
The system enables dynamic adjustment of vertebral alignment through the angulation module and rotatable arm mechanism. The adaptor allows real-time modification of angles and positions during surgery, transforming static implant supports into dynamically adjustable manipulation tools for achieving precise vertebral alignment
2Adaptability or versatility
If fixed-angle implants are used, then structural stability is achieved, but ability to correct various spinal deformities is limited
Solution Approach 1:
The system is segmented into modular components: implant supports fixed in vertebral tissue, adaptors with rotatable arms for angular adjustment, angulation modules for precise angle control, and surgical instruments for manipulation. This segmentation allows each component to perform its specific function while enabling versatile correction of different spinal deformities through combination and adjustment
Solution Approach 2:
The adaptor design with its arm structure, transverse member recess, and engagement mechanisms serves multiple functions: connecting implant supports to surgical instruments, providing angular adjustment capability, maintaining structural stability during manipulation, and enabling correction of various spinal deformities. This multi-functionality reduces the need for multiple specialized devices
3Manufacturing precision
If manual manipulation methods are used, then surgical simplicity is maintained, but precision and control during manipulation are insufficient
Solution Approach 1:
The system replaces manual manipulation with a controlled mechanical system consisting of the adaptor, angulation module, and surgical instruments. The angulation module provides precise angular control through mechanical adjustment mechanisms, while the adaptor's arm and recess structure enable accurate positioning and transmission of forces, replacing imprecise manual techniques with controlled mechanical manipulation
