Adjustable Surgical Guide for Wedge Osteotomy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical systems for forming cuts in bones during arthrodesis procedures, such as Charcot disease treatment, pose infection risks, slow tissue healing, and require time-consuming methods involving frames and burrs with long incision paths, lacking precision and efficiency.
Innovation Solution
An adjustable surgical guide with pivotable guide arms and sliding elements allows for precise angular and longitudinal adjustments, enabling accurate positioning of cutting guides for forming wedge osteotomies with reduced tissue trauma and incision length.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If current surgical systems use frames and burrs for forming bone cuts, then bone cutting can be achieved, but the procedure becomes time-consuming and requires long incision paths
Solution Approach 1:
The surgical guide is prepared beforehand with pre-configured guide arms, openings, and pivot elements that define the exact cutting path. This preliminary preparation eliminates the need for time-consuming intraoperative adjustments and frame placement, directly reducing surgical time while maintaining cutting accuracy
Solution Approach 2:
The surgical guide acts as an intermediary device between the surgeon's planning and the actual bone cutting. It translates preoperative planning into precise intraoperative execution by providing predetermined opening locations and guide arm orientations, eliminating the need for time-consuming burr-based shaping
2Productivity
If current surgical systems use frames and burrs for forming bone cuts, then bone cutting can be achieved, but infection risks increase and tissue healing is slowed
Solution Approach 1:
The invention extracts and eliminates the need for burrs and frames from the surgical procedure. By using a pre-configured surgical guide with predetermined openings, the harmful elements (burrs generating heat and debris, frames requiring extensive soft tissue dissection) are completely removed, thereby reducing infection risk and promoting faster tissue healing while maintaining cutting accuracy
Solution Approach 2:
The surgical guide is designed as a disposable, single-use device that is discarded after one procedure. This eliminates the need for sterilization and reuse of complex instruments like frames and burrs, reducing infection risks associated with repeated sterilization cycles and extensive tissue manipulation
3Ease of operation
If current surgical systems use fixed guide structures, then positioning can be simplified, but adaptability to different angular requirements is limited
Solution Approach 1:
The surgical guide incorporates dynamic elements including pivot elements that allow rotation of guide arms relative to each other, and sliding elements that enable longitudinal adjustment of guide arm positions. These dynamic features maintain ease of operation through intuitive mechanical adjustments while providing versatile angular adaptation to different surgical requirements
Solution Approach 2:
The surgical guide is divided into separate modular components: first and second guide arms that can be independently positioned, pivot elements that allow angular adjustment between arms, and sliding elements that enable longitudinal repositioning. This segmentation provides adaptability to various angular requirements while keeping each component simple and easy to operate

AI summary
A surgical guide includes a first guide arm extending from a first end to a second end on a first longitudinal axis. The first guide arm defines a first plurality of openings sized and configured to receive a first guide element therethrough. A second guide arm extends from a first end to a second end on a second longitudinal axis. The second guide arm defines a second plurality of openings sized and configured to receive a second guide element therethrough. A pivot element couples the first end of the first guide arm to the first end of the second guide arm such that an angular distance between the first guide arm and the second guide arm can be adjusted in a first plane.
