Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vascular clip production elements have limitations due to their small dimensions, leading to higher manufacturing costs and suboptimal clamping characteristics, which are inadequate for applications involving small blood vessels.
Innovation Solution
A vascular clip production element comprising a support plate, clip tab, and cylindrical sector brackets with through holes, secured by a single-piece molding, allowing for reduced manufacturing costs and enhanced clamping capabilities, with additional features like recesses and notches for elastic ring placement to apply radial tensile force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional production elements are used for small blood vessels, then the clips can be produced, but the manufacturing cost is high and clamping characteristics are suboptimal
Solution Approach 1:
The production element is divided into distinct functional components: a support plate providing structural foundation, cylindrical sector brackets creating precise through-holes for alignment, and a clip tab with gripping face for application. This segmentation allows each component to be optimized independently while maintaining overall functionality, reducing manufacturing complexity and cost.
Solution Approach 2:
Multiple functional elements (support plate, brackets, clip tab, elastic ring placement features) are merged into a single integrated production element that can be manufactured as one piece. This consolidation eliminates the need for multiple separate components and assembly steps, significantly reducing manufacturing cost while ensuring precise geometric relationships between features.
2Manufacturing precision
If the production element is designed with precise cylindrical sector brackets and through holes, then clamping characteristics are improved, but device complexity increases
Solution Approach 1:
The brackets are designed as cylindrical sectors with specific geometric parameters (radius, arc angle, thickness) that directly control the position and orientation of through-holes. By carefully selecting these parameters, the element achieves precise clamping characteristics with consistent force distribution across the clip tabs, while the standardized cylindrical sector form maintains manufacturing simplicity.
Solution Approach 2:
The production element appears to be manufactured as a single integrated component, likely using injection molding or similar processes. This monolithic construction combines multiple functions (support, positioning, clamping) into one piece with uniform material properties, avoiding the complexity of assembling multiple parts while maintaining precise geometric tolerances.
3Volume of moving object
If the element is designed for minimal size to accommodate small blood vessels, then applicability to small vessels is improved, but manufacturing precision requirements increase
Solution Approach 1:
The brackets are designed as cylindrical sectors with curved surfaces rather than sharp edges. This curvature provides natural stress distribution and tolerance to minor dimensional variations, allowing the element to maintain functionality at minimal size while reducing the stringency of manufacturing precision requirements. The rounded geometry also facilitates easier fabrication with standard molding processes.

AI summary
Disclosed are elements for producing a vascular clip and vascular clips produced with these elements. The element is essentially characterized by the fact that it includes a support plate, a clip tab including a gripping face, a unit for securing the clip tab and the edge face of the plate, two substantially identical brackets, each bracket substantially having the shape of a cylinder sector with a thickness Ep and including a through hole with an axis parallel to the generatrix of the cylinder, and a unit to secure the two brackets and the plate in such a way that the axes of the two holes are located on the same straight line perpendicular to the tab and that the opposite faces of the two brackets are set apart from each other by a value equal to the thickness Ep.
