Burr Hole Insertion Tool Even Pressure Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing burr hole cap insertion tools often result in uneven pressure distribution during the insertion of support clips, leading to potential misplacement and misalignment of leads or catheters in burr hole cap assemblies, which can be undesirable during medical procedures like deep brain stimulation.
Innovation Solution
A burr hole device insertion tool is designed to simultaneously apply a normal force to multiple attachment points of a support clip, ensuring even pressure distribution and stable fixation within the burr hole cap assembly, thereby reducing the risk of misplacement and misalignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a burr hole cap insertion tool attaches to a feature located on one side of the burr hole cap, then the tool can be operated easily, but uneven distribution of pressure occurs during insertion
Solution Approach 1:
The insertion tool's engagement feature is divided into multiple engagement points (first engagement point and second engagement point) that contact separate features on the support clip. This segmentation allows the tool to apply force at multiple locations simultaneously, distributing pressure evenly across the support clip during insertion, while maintaining operational simplicity through the unified tool structure.
2Reliability
If pressure is applied to insert the support clip, then the support clip is fixed in the burr hole cap assembly, but lead and catheter misplacement and misalignment occur due to uneven pressure
Solution Approach 1:
The tool engages with multiple features on the support clip through segmented engagement points, distributing insertion force across multiple locations. This prevents concentrated pressure that could deform the support clip or displace the lead, ensuring both reliable fixation and precise lead placement simultaneously.
Solution Approach 2:
The insertion tool combines multiple engagement points into a single integrated tool structure, allowing simultaneous application of force at multiple locations on the support clip. This merging approach ensures uniform pressure distribution while maintaining a single operational interface for the practitioner.
