Computer Visual Guidance for Hip Arthroscopic Debridement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current minimally-invasive treatments for hip joint pathologies, particularly cam-type and pincer-type femoroacetabular impingement, face challenges due to the complex anatomy and limited access within the hip joint, leading to difficulties in accurately guiding bone resection during arthroscopic procedures.
Innovation Solution
A novel computer visual guidance system that analyzes 2D X-ray images from a C-arm device to automatically measure and annotate features such as the Alpha Angle and Center Edge Angle, providing real-time guidance to surgeons during arthroscopic debridement procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If minimally-invasive arthroscopic procedures are used to treat hip joint pathologies, then patient recovery time and surgical trauma are reduced, but the ability to accurately guide bone resection is compromised due to limited access and complex anatomy
Solution Approach 1:
The patent introduces image guidance systems and navigation tools as intermediaries between the surgeon and the surgical site. These systems provide real-time visual feedback and anatomical landmarks, enabling accurate bone resection guidance through small incisions without requiring direct visual exposure of the surgical field.
Solution Approach 2:
The patent replaces direct mechanical visualization and manual guidance with image-based navigation systems. Computer-assisted navigation and intraoperative imaging replace the need for large open incisions, allowing precise bone resection through minimally-invasive approaches by substituting mechanical direct vision with digital imaging and computational guidance.
2Manufacturing precision
If open surgical procedures are used to access the hip joint for treating cam-type and pincer-type femoroacetabular impingement, then accurate bone resection can be achieved, but patient trauma and recovery time increase significantly
Solution Approach 1:
The patent employs image guidance and navigation systems as intermediaries that transmit anatomical information to the surgeon through small incisions. These systems provide real-time feedback on bone resection progress and anatomical relationships, enabling open surgical precision through minimally-invasive access by mediating between the limited surgical view and the complex hip joint anatomy.
Solution Approach 2:
The patent substitutes the mechanical requirement for large open incisions with digital imaging and computer-assisted navigation systems. These technologies replace the need for direct visual and tactile access to the hip joint, allowing surgeons to achieve accurate bone resection through small incisions by substituting mechanical exposure with digital visualization and computational guidance.
3Reliability
If the hip joint is treated as a mobile weight-bearing joint requiring substantial access for surgery, then complete pathology treatment is possible, but the risk of complications and extended recovery increases
Solution Approach 1:
The patent introduces image guidance systems as intermediaries that provide comprehensive anatomical visualization through small incisions. These systems mediate between the limited physical access and the need for complete pathology treatment by transmitting detailed anatomical information and treatment progress data, enabling thorough treatment without the need for large open incisions that increase complication risks.
Solution Approach 2:
The patent replaces the mechanical requirement for substantial surgical access with digital imaging and navigation technologies. These systems substitute the need for large open incisions and extensive tissue dissection with non-invasive or minimally-invasive imaging modalities, allowing complete pathology treatment while reducing surgical complications by eliminating the need for extensive mechanical access to the mobile weight-bearing hip joint.

AI summary
A computer visual guidance system for guiding a surgeon through an arthroscopic debridement of a bony pathology, wherein the computer visual guidance system is configured to: (i) receive a 2D image of the bony pathology from a source; (ii) automatically analyze the 2D image so as to determine at least one measurement with respect to the bony pathology; (iii) automatically annotate the 2D image with at least one annotation relating to the at least one measurement determined with respect to the bony pathology so as to create an annotated 2D image; and (iv) display the annotated 2D image to the surgeon so as to guide the surgeon through the arthroscopic debridement of the bony pathology.
