Modular Bone Canal Surgical Tool for Customizable Manufacturing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical tools for prosthetic surgery have high production costs and limited flexibility for customization, as they are typically made through forging or machining with chip removal, which require significant initial investments and long machining times.
Innovation Solution
A surgical tool with a cutting unit composed of autonomous, sequentially arranged cutting members and a central support member, produced using methods like 3D laser cutting or additive manufacturing, allowing for customizable and cost-effective production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If surgical tools are made through forging or machining with chip removal, then the tools achieve required structural strength and precision, but the production costs increase and manufacturing time extends
Solution Approach 1:
The surgical tool is divided into multiple autonomous cutting members arranged sequentially along a common longitudinal axis. Each cutting member can be independently produced and then assembled, allowing parallel manufacturing processes that reduce overall production time while maintaining the precision requirements of each individual component.
Solution Approach 2:
Multiple independently manufactured cutting members are combined into a single integrated tool assembly through a modular structure. This merging of separately produced components enables faster manufacturing compared to creating a single monolithic tool through traditional forging or machining, while achieving the required structural strength through the coordinated arrangement of members.
2Strength
If surgical tools are made through forging or machining with chip removal, then the tools achieve required structural strength, but the initial investment and production costs increase
Solution Approach 1:
The tool is segmented into multiple cutting members that can be produced using less expensive manufacturing methods compared to traditional forging or precision machining of a single complex component. This segmentation allows for more economical production while the assembled structure achieves the required overall strength through the coordinated arrangement of individual members.
Solution Approach 2:
The modular design with autonomous cutting members creates a universal platform that can be adapted for different surgical applications. The same basic structure and cutting member design can serve multiple functions and be customized for different procedures, reducing development and tooling costs associated with creating specialized tools for each application.
3Stability of the object's composition
If surgical tools are made as single-body structures through traditional methods, then the tools achieve structural rigidity, but the flexibility for customization decreases
Solution Approach 1:
The surgical tool is divided into multiple autonomous cutting members that can be independently designed and configured for specific surgical needs. This segmentation enables high customization flexibility as individual members can be tailored to different requirements while the modular assembly maintains structural rigidity through their coordinated arrangement along the longitudinal axis.
Solution Approach 2:
The modular structure with independently configurable cutting members creates a dynamic system that can be adapted and reconfigured for different surgical applications. The cutting members can be selectively assembled or removed based on specific procedural needs, providing adaptability while the overall structural framework maintains the required rigidity for stable operation.
