Arthroscopic Hip Debridement Guidance With Real-Time X-Ray Angles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surgeons lack the ability to make real-time anatomical measurements during hip surgeries, such as Alpha Angle and Center Edge Angle, due to the impracticality of moving patients between the operating and imaging rooms, disrupting sterility and wasting time, which affects the accuracy of bone resection in treating joint pathologies.
Innovation Solution
A computer visual guidance system that analyzes 2D images from an intra-operative X-ray device to automatically measure and annotate relevant angles, allowing surgeons to iteratively adjust bone resection based on these measurements, providing real-time guidance for precise debridement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the patient is moved out of the operating room to the imaging room to obtain updated measurements, then the measurement precision is improved, but the loss of time increases and the sterility of the surgical site cannot be maintained
Solution Approach 1:
The patent introduces a C-arm X-ray device as an intermediary imaging system that can be positioned within the operating room. This mediator enables acquisition of anatomical images without requiring patient transfer to a separate imaging room, thus maintaining surgical flow and sterility while obtaining necessary measurements for bone resection guidance
Solution Approach 2:
The patent replaces the traditional mechanical workflow of physically moving the patient between rooms with a digital imaging system (C-arm X-ray) that can be brought to the surgical site. This substitution eliminates the time-consuming mechanical transfer process while maintaining the ability to obtain precise anatomical measurements
2Measurement precision
If the patient is moved out of the operating room to the imaging room to obtain updated measurements, then the measurement precision is improved, but the sterility of the surgical site is compromised
Solution Approach 1:
The C-arm X-ray device serves as an intermediary imaging tool that can be positioned within the sterile field or immediately adjacent to it. This allows acquisition of necessary anatomical images without breaching the sterile barrier by transporting the patient outside the operating room, thus maintaining sterility while obtaining measurements
3Productivity
If real-time imaging and measurement is implemented during surgery, then the productivity is improved, but the device complexity increases
Solution Approach 1:
The C-arm X-ray device provides multiple functions including imaging, measurement, and guidance capabilities in a single integrated system. This multi-functionality enables real-time anatomical assessment during surgery without requiring multiple separate devices, thus improving surgical productivity while limiting the increase in overall system complexity
Solution Approach 2:
The patent replaces complex manual measurement procedures with an automated digital imaging and measurement system. The C-arm X-ray device with integrated software automatically performs measurements and provides real-time feedback, substituting manual processes with automated ones that improve efficiency without proportionally increasing complexity
