Problem
Current surgical navigation systems face challenges with complex connection structures for cascade tubes, leading to inconvenient disassembly and assembly, and inaccuracies due to occlusions in narrow oral spaces, especially in electromagnetic tracking methods.
Innovation Solution
A stackable quick-release apparatus with a connection rod, abutment rod, and elastic member is used to connect cascade tubes, featuring a connection groove system that allows for easy assembly and disassembly, enhanced stability, and improved precision through the use of an elastic member to secure the connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a complex connection structure is used for cascade tubes, then connection stability is improved, but disassembly and assembly convenience deteriorates
Solution Approach 1:
The connection structure is divided into modular components: a connection rod with mounting groove, an abutment rod with connection pin, and an elastic member. These segmented parts can be independently manufactured and assembled, simplifying the overall assembly process while maintaining connection stability through the coordinated interaction of the components.
Solution Approach 2:
The elastic member automatically engages the connection pin with the mounting groove when the abutment rod is inserted, creating a self-locking mechanism. This self-service feature ensures stable connection without requiring additional fastening operations, while still allowing easy disassembly by simply pulling the abutment rod out.
2Measurement precision
If optical tracking is used for positioning, then positioning accuracy is improved, but applicability in deep lacunar deteriorates due to tissue occlusion
Solution Approach 1:
The surgical navigation system integrates multiple tracking methods (optical tracking and electromagnetic tracking) into a single platform. The cascade tube connection apparatus can accommodate different tracking modules, allowing the system to switch between optical tracking for general use and electromagnetic tracking for deep lacunar applications, thus achieving multi-functionality and broad adaptability.
3Adaptability or versatility
If electromagnetic tracking is used for positioning, then applicability in deep lacunar is improved, but positioning accuracy deteriorates
Solution Approach 1:
The system design allows selective use of electromagnetic tracking module for deep lacunar applications where optical tracking is blocked, while maintaining the option to use optical tracking for higher precision in accessible areas. The cascade tube apparatus supports both tracking methods, enabling clinicians to choose the most appropriate method for each specific surgical scenario.
4Adaptability or versatility
If cascade tubes are adjusted by disassembly and assembly, then length adaptability is improved, but working efficiency deteriorates
Solution Approach 1:
The cascade tube system is segmented into multiple adjustable sections connected by the quick-release apparatus. Each section can be independently added or removed by simply connecting or disconnecting the abutment rod from the connection rod, enabling rapid length adjustment without complex disassembly procedures and significantly improving working efficiency.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The apparatus simplifies the connection process, enhances stability, and reduces errors by allowing for quick adjustment of tube lengths and rotation, improving the accuracy and flexibility of surgical navigation systems.
Implementation Method 1
The elastic member is configured to abut against the abutment rod, to enable the connection pin on the outer wall of the abutment rod to be engaged in the third groove
