Pivoting Wire Lead Anchor for Stable Surgical Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire leads in surgical procedures are prone to inadvertent dislodgement or movement, leading to suboptimal positioning, tissue irritation, inflammation, infection risk, and mechanical stress, compromising their reliability and effectiveness.
Innovation Solution
A wire lead anchoring device with a pivotable anchor and frame configuration that secures wire leads by allowing reconfiguration between open and closed states, using latches and a cap to lock the device in place, ensuring stable fixation within a patient's tissue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wire leads are secured with simple anchors, then the device complexity is low, but the wire leads are prone to dislodgement and movement compromising reliability
Solution Approach 1:
The anchor is divided into multiple segments including a first body portion, a second body portion, and a frame portion that can move relative to each other. This segmentation allows the anchor to transition between open and closed configurations, providing securement of the wire lead while maintaining a manageable structural complexity through modular design
Solution Approach 2:
The anchor incorporates dynamic elements that allow it to change configuration from open to closed state. The frame portion can move relative to the body portions, enabling the anchor to adapt its structure during deployment to achieve reliable wire lead securement without requiring a permanently complex structure
2Object-affected harmful factors
If wire leads are allowed to move freely, then the ease of operation is high, but tissue irritation and inflammation occur
Solution Approach 1:
The anchor is pre-configured with specific geometric features including angled surfaces and interlocking components that automatically engage to secure the wire lead in the correct position. This preliminary design ensures proper positioning and prevents tissue irritation without requiring complex manual adjustment operations during the procedure
3Reliability
If anchors are designed to fully restrict wire lead movement, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The anchor combines multiple functional elements into a single integrated structure that includes the first body portion, second body portion, and frame portion. This merging of components achieves reliable wire lead fixation through coordinated movement and engagement of the parts, avoiding the need for separate complex mechanisms for each function

AI summary
An anchoring device that is configured to receive a wire lead during a surgical procedure and which includes an anchor and a frame. The anchor defines a longitudinal axis and is configured for insertion into an access site in a patient. The anchor includes a first body portion and a second body portion that is pivotably connected to the first body portion such that the anchoring device is reconfigurable between an open configuration and a closed configuration. The frame is connected to the anchor and is configured to facilitate reconfiguration of the anchoring device between the open configuration and the closed configuration.
