Integrated Broach Trial Member Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current orthopedic surgery techniques face challenges in efficiently determining the optimal geometry for implantable devices, particularly in cases with bone loss or damage, as they require separate tools for broaching and placing trial components, complicating the surgical procedure.
Innovation Solution
A combination broach and trial member system that includes an alignment member, allowing for simultaneous broaching and alignment of the trial component with the patient's anatomy, simplifying the process by integrating these steps into one procedure and ensuring accurate placement of orthopedic implants like those used in total knee arthroplasty.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate tools are used for broaching and placing trial components, then each function can be performed with specialized equipment, but the surgical procedure becomes more complex and time-consuming
Solution Approach 1:
The patent combines the broach and trial member into a single integrated combination broach and trial member. The broach portion performs the broaching function while the trial member portion provides the trial component placement function, eliminating the need for separate tools and reducing procedural complexity while maintaining both functions
2Measurement precision
If multiple separate tools are used for broaching and alignment, then each function can be optimized independently, but the surgical time and number of steps increase
Solution Approach 1:
The alignment member is integrated with the combination broach and trial member, allowing alignment functionality to be combined with broaching and trial component placement. This reduces the number of separate steps and tools needed while maintaining alignment accuracy through the integrated design
Solution Approach 2:
The alignment member provides alignment guidance before and during the broaching process, allowing the surgeon to establish proper alignment prior to broaching and trial component insertion, thereby ensuring accuracy while reducing the need for subsequent adjustment steps

AI summary
An orthopedic system according to one embodiment of the disclosure comprises a first trial member capable of forming a broach cavity in a first bone of a patient. A second trial member is removeably coupleable to the first trial member in a fixed alignment with respect to the trial member. An alignment member is removeably coupleable in a fixed alignment with respect to the first trial member. The alignment member comprises indicia configured to provide for alignment of the alignment member with respect to at least one of the first bone and a second bone of the patient. The alignment of the second trial member with respect to the first trial member when coupled to the first trial member corresponds to the alignment of the alignment member with respect to the first trial member when coupled with the first trial member.
