1Object-affected harmful factors
If conventional IUD insertion devices are used, then the insertion procedure can be performed, but patient pain and discomfort occur due to vagal reflex response
Solution Approach 1:
The insertion device incorporates a rotatable string controller that allows dynamic adjustment of string tension and positioning during insertion. This dynamic control enables the operator to optimize the insertion process, reducing patient discomfort while maintaining ease of operation through real-time adjustments.
Solution Approach 2:
The device uses strings as intermediary elements that can be independently controlled and adjusted. These strings mediate between the insertion device and the IUD, allowing for controlled manipulation that reduces trauma to cervical tissues and minimizes vagal reflex response while maintaining operational simplicity.
2Ease of operation
If conventional IUD insertion devices are used, then the insertion procedure can be performed, but smooth operability is lacking
Solution Approach 1:
The rotatable string controller provides dynamic control over string tension and positioning, enabling smooth and controlled manipulation of the IUD during insertion. This dynamic mechanism enhances operability without significantly increasing device complexity, as it integrates into the existing insertion device structure.
Solution Approach 2:
The string control function is segmented into a separate rotatable controller, allowing independent adjustment of each string. This segmentation enables precise control and smooth operation while keeping the overall device design modular and manageable, preventing excessive complexity.
3Ease of operation
If conventional IUD insertion devices are used, then the insertion procedure can be performed, but the devices are difficult to use
Solution Approach 1:
The rotatable string controller provides tactile feedback to the operator through rotational resistance and positioning stops, enabling precise control of string tension. This feedback mechanism enhances ease of use by allowing intuitive manipulation while ensuring reliable insertion control through controlled resistance and positioning.
Solution Approach 2:
The strings serve as intermediaries that translate rotational motion of the controller into linear tension adjustments. This intermediary mechanism simplifies the user interface, making the device easier to use while maintaining reliable control over IUD positioning through the mechanical advantage of the string system.
