Rotatable Surgical Guide for Spinal Implant Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical methods for treating spinal disorders often require invasive procedures and lack precision in orienting surgical instruments relative to spinal implants, which can lead to suboptimal alignment and stability during healing.
Innovation Solution
A surgical guide system that includes a rotatable and pivotable member with locking elements, allowing for selective orientation of surgical instruments relative to spinal implants, facilitating minimally invasive procedures and adjustable screw angles for improved alignment and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional surgical methods are used for implant placement, then the procedure can be completed with simpler equipment, but the alignment precision and stability of spinal implants deteriorate
Solution Approach 1:
A surgical guide member is introduced as an intermediary device between the surgeon and the spinal implant. The guide member includes a cavity for receiving surgical instruments and locking elements for mating engagement with the spinal implant, enabling precise orientation and alignment during the surgical procedure without requiring overly complex equipment systems.
Solution Approach 2:
The surgical guide member is prepared in advance with pre-configured locking elements and instrument cavities. The locking elements are designed to mate with specific features on the spinal implant, allowing the surgical instrument to be pre-positioned and pre-oriented before the actual implantation, thereby ensuring precision without increasing operational complexity.
2Adaptability or versatility
If fixed orientation surgical guides are used, then the device structure can be simpler, but the adaptability to different screw angles and implant orientations deteriorates
Solution Approach 1:
The surgical guide member incorporates a rotatable component that allows dynamic adjustment of the surgical instrument's orientation relative to the spinal implant. The locking elements enable the guide to be selectively rotated to different angles and then locked in place, providing adaptability for various screw angles and implant orientations while maintaining a relatively simple device structure.
Solution Approach 2:
The surgical guide member is divided into separable components including the main body, the rotatable instrument-holding section, and the locking elements. This segmentation allows each component to be optimized independently and facilitates easy adjustment of the instrument orientation by rotating the appropriate segment without complicating the overall device design.
3Object-affected harmful factors
If minimally invasive techniques are used, then patient trauma is reduced, but the precision in orienting surgical instruments relative to implants deteriorates
Solution Approach 1:
The surgical guide member serves as a precision intermediary device that can be introduced through minimally invasive approaches. It provides the necessary precision for instrument orientation and implant alignment without requiring large incisions or extensive exposure, thereby reducing patient trauma while maintaining high precision through its structured cavity and locking mechanism.
