Osteotomy Cut Guide With Detachable Aligner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surgical cutting and aligning guides for osteotomy procedures often struggle with proper alignment, restricting visibility and access to the osteotomy site, leading to increased surgical time and potential bone damage due to the need for multiple installations and removals, and may not allow for ideal bone removal based on individual patient anatomy.
Innovation Solution
A surgical system comprising a frame with adjustable sections and a cut guide that fits within a window, allowing for secure attachment to bones and a detachable aligner with a high friction surface, enabling precise alignment and minimal bone removal while maintaining visibility and access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a surgical cut guide is used to perform osteotomy, then cutting precision is improved, but visibility and access to the osteotomy site are restricted
Solution Approach 1:
The surgical guide system is divided into separate components: a frame structure that provides alignment and cutting guidance, and a detachable bone block or graft holder. This segmentation allows the guide to be removed or adjusted during surgery, maintaining cutting precision while improving visibility and access to the osteotomy site.
2Manufacturing precision
If a fixed cut guide is used, then alignment precision is improved, but adaptability to different bone removal requirements is reduced
Solution Approach 1:
The surgical guide incorporates adjustable elements such as movable bone block holders and configurable cutting guides that can be positioned at different angles and depths. This dynamic design maintains precise alignment capabilities while allowing customization for various bone removal requirements based on individual patient anatomy.
Solution Approach 2:
The guide system allows modification of key parameters including bone block position, cutting angle, and guide depth to match specific surgical requirements. This enables the same guide structure to adapt to different osteotomy needs while preserving alignment precision through maintained reference points.
3Manufacturing precision
If multiple installations and removals of cut guide are performed, then ideal alignment can be achieved, but surgical time increases and bone damage increases
Solution Approach 1:
The surgical guide is pre-configured with patient-specific alignment parameters and pre-attached to the bone structure using minimally invasive fixation methods. This preliminary preparation ensures ideal alignment is achieved from the first installation, eliminating the need for repeated guide placements and reducing both surgical time and bone trauma.
