IUD Thread Protection Device for Surgical Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During medical procedures like LEEP and conization, intrauterine device (IUD) removal threads are often damaged, making it difficult to retrieve the IUD and causing patient discomfort and increased costs.
Innovation Solution
A medical device with a conical retriever and shaft designed to grasp and protect IUD threads from damage, featuring a flange that catches the threads and prevents them from being cut during procedures, constructed from non-conductive materials to prevent electrical interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If IUD threads are left exposed during surgical procedures like LEEP and conization, then the surgical procedure can be performed, but the threads are damaged making retrieval difficult and causing patient discomfort
Solution Approach 1:
The patent introduces a protective device as an intermediary between the IUD threads and surgical instruments. This device includes a protective sheath that covers the threads and a retrieval mechanism with a grasping element, serving as a mediator that allows surgical procedures to occur while preventing thread damage and enabling post-procedure retrieval.
Solution Approach 2:
The protective device is installed on the IUD threads before the surgical procedure begins. The protective sheath is positioned to cover the threads in advance, and the retrieval mechanism is prepared beforehand, allowing the threads to be protected throughout the surgery and readily available for retrieval after the procedure.
2Reliability
If a protective device is added to protect IUD threads, then thread integrity is maintained, but device complexity increases
Solution Approach 1:
The protective device is divided into distinct functional segments: a protective sheath portion that covers the threads, a retrieval mechanism with a grasping element, and a shaft connecting them. This segmentation allows each component to perform its specific function independently while keeping the overall device manageable and relatively simple in structure.
