Integrated Cut Guide for Bone Resection and Compression Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical procedures for correcting hallux valgus deformities, such as bunions, are inefficient and require multiple steps due to the need for separate tools and components, which can complicate the process and prolong recovery time.
Innovation Solution
A cut guide system with integrated fixation and attachment features, including a sliding mechanism and multiple apertures, allows for precise bone resection and simultaneous attachment of compression devices, reducing the number of steps and enhancing procedural efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate tools and components are used for bone resection and compression, then each component can be optimized for its specific function, but the surgical process becomes more complex and time-consuming
Solution Approach 1:
The patent combines the cut guide, compression device, and fixation wire into a single integrated system. The cut guide includes a body with apertures for guiding surgical tools, a fixation hole for receiving a wire, and an attachment hole for coupling to the compression device. This merging eliminates the need for separate tools and components, reducing surgical complexity while maintaining functional optimization.
Solution Approach 2:
The cut guide body serves multiple functions simultaneously: it guides bone resection through apertures, provides fixation through a wire-receiving hole, and enables compression device attachment through an attachment hole. This multi-functionality reduces the number of separate components needed during surgery.
2Manufacturing precision
If multiple separate steps are used for guiding bone cuts and attaching compression devices, then each step can be performed with dedicated tools, but the overall surgical duration increases
Solution Approach 1:
The integrated system allows the surgeon to perform bone resection guidance and compression device attachment in a single surgical session without removing or repositioning components. The cut guide remains in place throughout, eliminating time lost in transitioning between separate procedures.
Solution Approach 2:
The cut guide is pre-positioned and secured to the bone before the surgical procedure begins, establishing the precise alignment and orientation needed for accurate bone resection. The compression device is then attached to the same guide, ensuring both precision and efficiency.
3Productivity
If an integrated cut guide system is used, then the surgical process is streamlined and time is reduced, but the device structure becomes more complex
Solution Approach 1:
The integrated cut guide is divided into distinct functional segments within a single body: apertures for tool guidance, a fixation hole for wire attachment, and an attachment hole for the compression device. This segmentation allows each feature to perform its specific function while maintaining overall integration.

AI summary
A cut guide includes a body having a first face and an opposed second face. The first face of the body defines first and second apertures, a first fixation hole, and an attachment hole. The first and second apertures are configured to guide a surgical tool, and the first fixation hole extends through the cut guide from the first face to the second face and is configured to receive a wire to position the cut guide against a bone. The attachment hole is configured to attach the cut guide to another component. A system including the cut guide and methods of using the system also are disclosed.
