Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing endoscopic viewing systems lack the capability for efficient control of imaging and fluid management from a hand-held unit, which can lead to difficulties in maintaining proper orientation and fluid pressure during medical procedures.
Innovation Solution
The development of an endoscopic system that includes a handle with a rotatable C-mount coupler assembly, an image sensor, and at least one accelerometer or gyroscope. This system allows for the acquisition of signals from the accelerometers or gyroscopes to correct the orientation of the displayed image and control fluid management parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a hand-held unit is used to control imaging and fluid management, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent combines the image sensor, accelerometer, gyroscope, and fluid management controls into a single integrated hand-held unit that attaches to the endoscope. This merging of multiple functions into one portable device allows the operator to control imaging and fluid management from a single location, improving ease of operation while the modular design keeps the overall system manageable.
Solution Approach 2:
The hand-held unit is designed with multi-functionality, serving as both an image capture device and a fluid management control interface. The same unit houses the image sensor for visual feedback and the accelerometer/gyroscope for orientation control, while also providing controls for fluid flow regulation. This universal design reduces the need for separate devices and simplifies the operator's workflow.
2Adaptability or versatility
If the C-mount coupler assembly is made rotatable, then adaptability is improved, but device complexity increases
Solution Approach 1:
The C-mount coupler assembly is designed to be rotatable relative to the endoscope shaft, allowing dynamic repositioning of the image sensor and controls. This rotational capability enables the operator to adapt the device to different procedural requirements and patient positions. The rotatable mechanism is integrated into the handle assembly, providing adaptability without requiring a completely redesign of the endoscope interface.
3Measurement precision
If accelerometers and gyroscopes are added to the C-mount coupler, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent replaces complex mechanical orientation adjustment mechanisms with electronic sensors (accelerometers and gyroscopes) that electronically detect the device's orientation and position. Instead of using mechanical linkages and physical adjustments to maintain proper imaging orientation, the system uses sensor data to automatically compensate for position changes, improving measurement precision while reducing mechanical complexity.
4Ease of operation
If electrical leads are configured with slack portions, then ease of operation is improved, but manufacturing precision deteriorates
Solution Approach 1:
The electrical leads are designed with flexible, slack portions that allow the rotatable C-mount coupler assembly to rotate without straining the electrical connections. These flexible segments act as buffer zones, accommodating the rotational movement while maintaining reliable electrical contact between the hand-held unit and the endoscope. This design prioritizes operational flexibility over rigid manufacturing precision for the lead configuration.
