Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for securing medical instruments and devices in minimally invasive surgical procedures are inaccurate, time-consuming, costly, and not patient-friendly, particularly in radiology and oncology, due to limitations in fixation techniques such as straps, screws, and thermoplastic materials.
Innovation Solution
A device with a support element featuring an adhesive layer and a fine-positioning unit with snap closure mechanism, allowing quick and precise placement of calibration points, using vacuum for stability adjustment, and remote operation via Bowden cables or spindles, with a radiolucent carbon mounting plate for reduced radiation exposure and hygienic disposable components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional fixation methods (straps, screws, thermoplastic material) are used, then the device can be secured to the body, but the fixation accuracy is poor and the application is time-consuming
Solution Approach 1:
The support member undergoes a parameter change from a stable dimension to a formable condition through vacuum release, allowing easy adaptation to body contours and rapid application while maintaining secure fixation accuracy
Solution Approach 2:
The support member transitions between stable and formable states dynamically, enabling quick application and removal while maintaining high fixation accuracy during the procedure
2Reliability
If conventional fixation methods are used, then the device can be secured, but the procedure is costly and time-consuming
Solution Approach 1:
The vacuum-stabilized support member provides reliable fixation when needed while allowing rapid deployment and removal, significantly improving procedure efficiency and reducing costs
Solution Approach 2:
The support member is designed as a disposable component that provides reliable fixation for the duration of the procedure, then is discarded, eliminating cleaning and sterilization costs while maintaining high reliability
3Reliability
If the support member is made stable for secure fixation, then fixation reliability is high, but the support member cannot be easily removed or repositioned
Solution Approach 1:
The support member dynamically transitions between stable and formable states through vacuum control, providing secure fixation during the procedure while enabling easy removal or repositioning when needed
Solution Approach 2:
The physical state of the support member changes from stable to formable through parameter adjustment (vacuum release), allowing it to maintain secure fixation when needed and be easily manipulated for removal when required

Implementation Method 1
a support element which is preferably positioned with an adhesive layer on the body surface
Implementation Method 2
The support member can be reversibly transferred from a stable dimension into a formable condition, in particular by releasing or applying vacuum in the carrier element
