Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tool posture control devices struggle to accurately target abnormal tissues due to limitations in controlling the bending angle of tools, such as needles or cautery tools, especially when the abnormal tissue is located at varying positions.
Innovation Solution
A tool posture control device comprising a plurality of airbags, a gas supply module, and a controller, where the tool is positioned between the airbags, and the controller adjusts the gas supply to the airbags based on a target bending angle value, allowing precise control of the tool's posture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional rigid tool is used for tissue detection and processing, then the tool structure is simple and easy to manufacture, but the tool cannot accurately target abnormal tissues located at varying positions due to inability to adjust bending angle
Solution Approach 1:
The tool is divided into multiple segments with airbags positioned between them. Each airbag can be independently inflated to bend specific segments of the tool, enabling multi-directional posture adjustment. This segmentation allows the tool to adapt to various abnormal tissue locations while maintaining a relatively simple overall structure.
Solution Approach 2:
The tool transitions from a rigid structure to a dynamic, flexible structure through the incorporation of airbags. By controlling gas supply to different airbags, the tool can dynamically adjust its bending angle and posture to accurately target abnormal tissues at varying positions, solving the adaptability problem.
2Manufacturing precision
If no posture control mechanism is used, then the device is simple and easy to operate, but the tool cannot achieve precise bending angle control to target abnormal tissues
Solution Approach 1:
The control system incorporates feedback mechanisms to monitor and adjust the bending angle of the tool. By measuring the actual posture and comparing it with the target bending angle, the system can make precise adjustments to achieve accurate targeting of abnormal tissues, thereby improving manufacturing precision in terms of posture control.
Solution Approach 2:
The patent uses pneumatic airbags controlled by a gas supply system to achieve precise bending angle control. By regulating gas pressure and flow to specific airbags, the system can precisely control the tool's posture and bending angle, enabling accurate targeting without overly complicating the control system.
3Adaptability or versatility
If multiple airbags are used to control tool posture, then the tool can accurately target abnormal tissues, but the device complexity increases due to multiple gas supply channels
Solution Approach 1:
The gas supply module is designed with multi-functionality to manage multiple airbags efficiently. A single gas supply system can control multiple airbags through standardized interfaces and control logic, reducing the overall complexity despite the presence of multiple airbags. The system can selectively activate different airbags based on the required tool posture.
Solution Approach 2:
The controller acts as an intermediary between the gas supply module and the airbags. It manages the complex gas supply distribution by processing control signals and coordinating gas flow to appropriate airbags, thereby simplifying the overall system architecture while maintaining accurate tool positioning capability.
