Intracorporeal Guide Component Bone Interlock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing guide components for medical device lines within a living being are difficult to fix in a manner that is both easy on the tissue and stable, particularly for transcutaneous lines, as they often require additional connecting means and can cause tissue injury.
Innovation Solution
A guide component with a base body that engages form-fit and/or force-fit with a bone structure, using contact faces on its circumference to secure itself without the need for screws or sutures, allowing for minimal invasive implantation and reduced tissue stress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional fixation methods (screws, sutures, additional connecting means) are used to secure the guide component, then the fixation stability is improved, but the tissue injury and complexity of the implantation procedure increase
Solution Approach 1:
The guide component is designed with self-fixating capabilities through its base body geometry that directly engages with bone structures. The component serves its own fixation function without requiring external connecting means, screws, or sutures, thereby reducing device complexity while maintaining fixation stability.
Solution Approach 2:
The invention extracts and eliminates the need for additional fixation elements (screws, sutures, connecting means) from the system. The guide component's base body is designed to inherently secure itself to the bone structure through form-fit engagement, removing the harmful factor of tissue injury caused by traditional fixation methods.
2Reliability
If additional connecting means are used to fix the guide component, then the fixation reliability is improved, but the ease of operation during implantation deteriorates
Solution Approach 1:
The guide component performs its own fixation through the base body's geometric design that complements the bone structure. This self-service mechanism ensures reliable fixation while simplifying the implantation procedure, as no additional connecting means need to be installed during surgery.
3Stability of the object's composition
If the guide component is designed to engage with bone structure, then the fixation stability is improved, but the harm to surrounding tissue increases
Solution Approach 1:
The guide component's base body is designed with localized engagement features that specifically interact with bone structures. This local quality design allows stable fixation at the bone interface while minimizing harm to surrounding soft tissues, as the engagement is concentrated at the appropriate anatomical location.
Solution Approach 2:
The invention converts the potential harm of bone engagement into a benefit by designing the base body to utilize the bone structure's geometric features for secure fixation. The bone structure, which could be considered a rigid anchor point, is transformed into a beneficial engagement surface that provides stability without requiring invasive fixation methods.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The guide component can be quickly and easily fixed to the intended site within the body, reducing tissue injury and providing a stable, secure hold for medical device lines, suitable for long-term use and transcutaneous applications.
Implementation Method 1
In the case of force-fit engagement, mutual displacement between guide component and bone structure is prevented on account of the static friction acting between the two components.

AI summary
The invention relates to an intracorporeal guide component (1) for guiding lines belonging to medical devices inside a living being. The guide component (1) has a main body (2) comprising a line channel (3) for receiving and guiding the line. To secure the guide component (1) in the body of the living being more easily, with less damage to the tissue, according to the invention the main body (2) has, on its periphery, one or more contact surfaces (4, 4b) designed for interlocking and/or frictional contact with a bone structure of the living being. For example, the guide component (1) can be clamped between two costal arches of the living being, as an intercostal guide component (1), in order to securely hold and guide a line leading to the heart of the living being.
