Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In minimally invasive surgeries like laparoscopic and thoracoscopic procedures, existing X-ray imaging devices clutter the operation room and expose medical staff to high radiation doses due to their large size and radiation requirements.
Innovation Solution
A compact X-ray imaging device with a rod, clamp module, X-ray emission, and sensing modules, and a manipulation module that allows for the insertion of the device into the body to emit and sense X-rays between clamp bodies, minimizing equipment footprint and radiation exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a C-arm X-ray imaging device is used to visually discriminate accurate resection margin from solitary pulmonary nodule, then imaging precision is improved, but the operation room becomes cluttered and medical staff are exposed to excessive radiation
Solution Approach 1:
The patent divides the X-ray imaging function into separate portable components (X-ray source and detector) that can be independently positioned and manipulated, rather than using a large integrated C-arm system. This segmentation allows the imaging function to be performed with minimal equipment in the operation room.
Solution Approach 2:
The patent extracts the essential X-ray imaging function from the bulky C-arm system and implements it using minimal components (rod, clamp module with X-ray source and detector). This extraction removes the harmful aspect (large equipment footprint and radiation exposure) while preserving the useful function (lesion visualization).
2Adaptability or versatility
If a C-arm X-ray imaging device is used to visually check lesions, then imaging capability is improved, but device complexity and space occupation increase
Solution Approach 1:
The patent combines the X-ray source, detector, and positioning mechanism into a single integrated rod assembly with clamp module. This merging reduces the number of separate components and simplifies the overall system while maintaining full imaging capability.
Solution Approach 2:
The rod assembly with clamp module serves multiple functions: positioning the X-ray source and detector, securing them during imaging, and enabling portable operation. This multi-functionality eliminates the need for separate positioning devices and large support structures.
3Manufacturing precision
If localization or marking is performed to mark lesions for excision, then surgical precision is improved, but operation time and procedure complexity increase
Solution Approach 1:
The patent performs X-ray imaging during the surgical procedure itself rather than requiring separate pre-operative localization procedures. The portable device allows rapid imaging that can be integrated into the surgical workflow without requiring additional setup time or separate marking steps.
