Radiotransparent Adapter Plane for Anterior Hip Surgery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional surgical tables are inadequate for hip replacement operations, particularly the anterior approach, as they are made of radiopaque materials, hindering radiographic techniques and lacking suitable positioning for the lower limb, leading to inefficiencies and potential complications during procedures.
Innovation Solution
An adapter plane for surgical tables made of radiotransparent material, with a secondary portion projecting beyond the table to support the pelvis and allow fluoroscopic imaging, and a connection member for positioning apparatuses, enabling better patient positioning and reducing stress on joints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional surgical table with radiopaque material is used, then the table provides structural support and stability, but it hinders radiographic imaging techniques such as fluoroscopy
Solution Approach 1:
The surgical table is divided into two distinct portions: a first portion made of radiopaque material for structural support, and a second portion made of radiotransparent material for imaging. This segmentation allows each portion to fulfill its specific function without interfering with the other, resolving the contradiction between structural integrity and radiographic transparency.
Solution Approach 2:
Different portions of the surgical table are assigned different material properties: the first portion (support structure) uses radiopaque material while the second portion (imaging area) uses radiotransparent material. This local differentiation of quality allows the table to simultaneously provide structural support and enable radiographic imaging in the required zone.
2Adaptability or versatility
If a conventional surgical table is used, then the table is cost-effective and versatile for different operations, but it lacks suitable positioning capabilities for anterior approach hip replacement surgery
Solution Approach 1:
The positioning apparatus is segmented into multiple components including a positioning device with support elements, connection members, and adjustable mechanisms. This segmentation allows the apparatus to be configured specifically for anterior approach hip replacement while maintaining the ability to be adapted for other surgical procedures.
Solution Approach 2:
The surgical table with the adapter plane and positioning apparatus is designed to be multi-functional. The radiotransparent second portion and positioning apparatus can be used for anterior approach hip replacement surgery, while the table maintains its basic functionality for other surgical operations, achieving versatility without requiring complete table replacement.
3Measurement precision
If the secondary portion projects with respect to the surgical table, then fluoroscopic imaging of the pelvis and bone site is enabled, but the device complexity increases
Solution Approach 1:
The second portion requiring radiotransparency is extracted as a separate component that can be coupled to the first portion of the surgical table. This extraction allows the radiotransparent portion to project beyond the table for optimal imaging positioning while keeping the main table structure simple and familiar.
Solution Approach 2:
The adapter plane serves as an intermediary component that connects the conventional surgical table to the radiotransparent second portion and positioning apparatus. This mediator simplifies the integration of complex imaging and positioning features while maintaining compatibility with existing surgical table infrastructure.
