Spinal Plate with Rotatable End Bodies for Spine Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional spinal plates are difficult to accurately modify to fit varying patient spine shapes, leading to incomplete attachment during surgery and potential side effects, and they are not designed for minimally invasive surgery (MIS) due to their inability to be easily shaped and inserted through small skin incisions.
Innovation Solution
A spinal plate with a rotation device and locking mechanism that allows the ends to be rotated and locked at desired angles, enabling the plate to be customized to fit different spine shapes and facilitating MIS by allowing insertion through smaller incisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional spinal plate with fixed shape is used, then the structure is simple and easy to manufacture, but it cannot accurately fit varying patient spine shapes leading to incomplete attachment
Solution Approach 1:
The spinal plate incorporates rotatable end bodies that can be adjusted to different angles and locked in position, transforming a static fixed-structure into a dynamic adjustable-structure. This allows the plate to adapt to various spine shapes while maintaining a relatively simple base design
Solution Approach 2:
The spinal plate is divided into separate functional components: a central body and rotatable end bodies with locking mechanisms. This segmentation allows each component to be optimized independently and assembled in different configurations to match patient-specific anatomy
2Ease of manufacture
If a conventional spinal plate with fixed shape is used, then the manufacturing process is simple, but modification for each patient situation is difficult and time-consuming
Solution Approach 1:
The plate maintains simple manufacturing through standardized components but gains ease of modification through the rotatable and lockable end bodies that can be adjusted intraoperatively without requiring custom manufacturing for each patient
3Adaptability or versatility
If a conventional spinal plate is used, then the design is simple, but it cannot be inserted through small skin incisions for minimally invasive surgery
Solution Approach 1:
The rotatable end bodies can be positioned to facilitate insertion through smaller incisions, and the locking mechanism secures the plate after placement, enabling minimally invasive surgery while maintaining structural integrity
Solution Approach 2:
The modular design with separate end bodies allows the plate to be configured for different surgical approaches, including minimally invasive techniques, without requiring a complete redesign of the entire device

AI summary
The present invention provides a spinal plate which is used to perform fixation surgery on a spine in orthopedic surgery and neurosurgery. The spinal plate comprises a central body and a pair of rotation portions which are disposed on both sides in a longitudinal direction of the central body and each of the pair of rotation portions has bone screw. The spinal plate also comprises spike screw in each of the pair of rotation portions. Each of the pair of rotation portions include a rotation connection portion, and the central body includes a rotation support portion. Rotation pins are used to connect the central body with the pair of rotation portions disposed on both sides in a longitudinal direction of the central body and enable the pair of rotation portions to rotate clockwise or counterclockwise with respect to the central body.
