Visible Abdominal Drainage Tube for Accurate Catheter Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current abdominal cavity drainage tubes are placed blindly, leading to inaccurate positioning of the catheter head, large surgical trauma due to exploratory celiotomy, and lack of visible flushing and drainage capabilities.
Innovation Solution
An endoscope-guided percutaneous visible device with a drainage tube, fluid injection and discharge tubes, a camera, and an adjustable display mechanism, allowing for precise abdominal cavity probing and accurate drainage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a bedside abdominal cavity drainage tube device is placed blindly, then the drainage procedure can be performed, but the actual position of the catheter head cannot be seen and a local lesion cannot be accurately located
Solution Approach 1:
A camera is introduced as an intermediary device inside the drainage tube to transmit visual information about the catheter head position and local lesions to the external display, enabling blind placement to be resolved without significantly increasing overall device complexity
Solution Approach 2:
The mechanical blind placement method is replaced with an optical detection system using a camera and display mechanism, allowing visual observation of the catheter head position and surrounding tissue conditions
2Measurement precision
If exploratory celiotomy is performed to locate lesions, then accurate positioning can be achieved, but large surgical trauma occurs
Solution Approach 1:
The camera acts as an intermediary that transmits real-time visual information about the abdominal cavity and lesion positions to the external display, eliminating the need for exploratory celiotomy and reducing surgical trauma while maintaining accurate lesion location capability
Solution Approach 2:
The mechanical exploratory surgery approach is replaced with an optical imaging system, allowing precise lesion location without incisions and reducing surgical trauma
3Reliability
If traditional drainage tube is used, then drainage can be performed, but visible flushing and drainage cannot be achieved resulting in drainage deviation
Solution Approach 1:
The camera serves as an intermediary that provides real-time visual feedback of the drainage path and fluid flow, enabling the operator to adjust and correct drainage deviation while maintaining reliable drainage accuracy
Solution Approach 2:
The display mechanism provides continuous visual feedback about the drainage status and fluid flow patterns, allowing real-time adjustment to maintain accurate drainage and prevent deviation
