Integrated Hip Surgical Guide System for Pelvic and Femoral Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical guide systems for orthopaedic surgeries, particularly for hip replacement, face challenges in accurately positioning surgical tools due to the lower reliability and accuracy of pelvic surgical guides compared to femoral guides, leading to potential misalignment and complications during procedures.
Innovation Solution
A surgical guide system with a body having first and second contact surfaces profiled to correspond to anatomical surfaces of the acetabulum and femur, respectively, which are configured to guide fasteners and surgical tools accurately, utilizing imaging data for patient-specific manufacturing and featuring detachable body portions for enhanced positioning and tool access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a surgical guide is configured for a particular patient using CT scan or MRI to determine anatomic landmarks, then the surgical guide can be placed in contact with the bone and cartilage to have a unique location, but the reliability and accuracy of pelvic surgical guides remains lower compared to femoral guides
Solution Approach 1:
The patent combines the pelvic surgical guide and femoral surgical guide into a single integrated system. The pelvic guide includes a body with contact surfaces for the acetabulum and a femoral component with contact surfaces for the femur, allowing simultaneous stabilization on both bones to improve overall accuracy and reliability
Solution Approach 2:
The surgical guide is divided into separable components including a pelvic portion and a femoral portion that can be selectively attached and detached. This segmentation allows for flexible positioning and stabilization on different anatomical structures while maintaining the ability to achieve unique location through combined contact points
2Adaptability or versatility
If a surgical guide is made patient-specific through manufacturing based on imaging data, then the guide can be tailored to individual anatomic landmarks, but the device complexity increases
Solution Approach 1:
The surgical guide system incorporates universal features such as standardized fastener interfaces, common reference structures, and modular components that can be used across different patients while still allowing patient-specific customization through the contact surfaces and positioning elements
Solution Approach 2:
The surgical guide is pre-configured with contact surfaces and geometric features that correspond to predetermined anatomic landmarks identified from imaging data. This preliminary configuration allows for accurate patient-specific positioning without requiring complex intraoperative adjustments or measurements
3Measurement precision
If the surgical guide has fixed body portions to maintain geometric relationship, then the positioning accuracy is improved, but the ease of operation and tool access is reduced
Solution Approach 1:
The surgical guide incorporates dynamically adjustable components including selectively detachable body portions and movable fastener guides that allow the surgeon to adjust the configuration for optimal tool access while maintaining the geometric relationship between contact surfaces through controlled attachment and detachment

AI summary
A surgical guide system for guiding a surgical tool, comprising a body which comprises a first contact surface profiled to locate with a first anatomical surface of a first bone; and a second contact surface profiled to locate with a second anatomical surface of a second bone; wherein the body is configured, for a specified functional position of the first bone relative to the second bone, to simultaneously: locate the first contact surface with the first anatomical surface; locate the second contact surface with the second anatomical surface; and receive, or guide, a first fastener to fasten to the first bone, wherein at least one of the body and/or the first fastener forms a first reference to guide a first surgical tool to the first bone.
