Bone Surgery Tool with Cartridge Guide for Single-User Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bone surgery methods for animal fracture models are complex and require simultaneous operation by two individuals, involving drilling a single hole followed by separate guide use, which is technically challenging and inefficient.
Innovation Solution
A bone surgery tool with a base, fixed arm, and sliding arm, featuring a cartridge system for guiding implant placement, allowing for single-user operation by aligning and securing implants directly onto the bone, eliminating the need for pilot holes and additional operators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single hole is drilled first before using a guide for other holes, then the implantation process can be completed, but the method becomes complex and requires two simultaneous operators
Solution Approach 1:
The patent combines multiple functions (drilling guide, implant holder, and positioning mechanism) into a single integrated implantation device. The device includes a body with a longitudinal axis, a drill guide at the front end for guiding drill bits, and an implant holder at the rear end for securing implants, allowing both drilling and implant placement to be performed by one operator through a unified tool rather than separate tools and operators
Solution Approach 2:
The implantation device serves multiple functions: it guides drilling operations through the drill guide, holds implants securely through the implant holder, and provides positioning accuracy through the longitudinal axis alignment. This multi-functional design eliminates the need for separate drilling tools and implant placement tools, reducing the number of operators needed while maintaining procedural completeness
2Adaptability or versatility
If fixation implants are miniaturized for murine models, then the implants can be adapted for small animal use, but the implantation method remains complex and technically challenging
Solution Approach 1:
The device is segmented into distinct functional components: a drill guide portion at the front end for precise hole drilling, a body portion connecting the components, and an implant holder at the rear end for secure implant retention. This segmentation allows each component to be optimized for its specific function while working together as an integrated system, making the device adaptable to small animal anatomy without increasing operational complexity
Solution Approach 2:
The body of the device acts as an intermediary structure that connects the drill guide and implant holder, providing structural support and alignment. This intermediary component ensures that the drilling operation and implant placement are coordinated through a single device, eliminating the need for complex manual coordination between multiple operators while maintaining precision in miniaturized murine models
3Productivity
If two users are required to cut the bone and obtain a final construct, then the procedure can be completed, but the procedure time and cost increase
Solution Approach 1:
The device merges the functions of bone cutting guidance and construct assembly into a single tool that can be operated by one user. The drill guide enables precise bone hole creation, while the implant holder facilitates immediate implant placement and construct assembly, allowing one operator to complete tasks that previously required two simultaneous operators, thereby reducing procedure time and associated costs
