Medical Suture Package Friction Reduction Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical suture packages face issues with high friction between the suture and the package, leading to a curling phenomenon and difficulty in drawing out the suture, especially when external forces are applied, which complicates the operation and convenience of use.
Innovation Solution
A medical suture package design featuring a main body with upper and lower parts and a winding depression, equipped with protrusion rods on the inner sidewall to reduce friction and supports between the body parts to maintain the shape of the winding depression, ensuring easy suture extraction without curling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the suture is wound around the main body in a conventional package, then the suture can be stored in the package, but high friction between the suture and the package occurs, making it difficult to draw out the suture and causing a curling phenomenon
Solution Approach 1:
The patent introduces protrusion rods as intermediary elements positioned between the suture and the inner sidewall of the winding depression. These rods act as mediators that support the suture during extraction, preventing direct contact between the suture and the friction-prone sidewall surface, thereby reducing friction and eliminating the curling phenomenon
Solution Approach 2:
The patent applies local quality by providing protrusion rods at specific locations on the curved surface of the inner sidewall where the suture makes contact during winding and extraction. This localized intervention reduces friction only at the critical contact points rather than requiring modification of the entire package surface
2Ease of operation
If external force is applied to the main body to draw out the suture, then the suture can be extracted, but the winding depression deforms and loses its original shape, impeding further suture extraction
Solution Approach 1:
The patent implements beforehand cushioning by providing support structures (protrusion rods and internal supports) within the winding depression before suture extraction occurs. These pre-positioned elements cushion and distribute the external force applied during suture drawing, preventing the winding depression from deforming and losing its shape
3Ease of operation
If the suture is drawn out in a diagonal direction to overcome friction, then the suture can be extracted, but the suture may be caught between the cover and the fixing protrusion, making it impossible to use
Solution Approach 1:
The protrusion rods serve as intermediaries that guide the suture along a smooth path during extraction, preventing the suture from deviating toward the cover and becoming caught between the cover and fixing protrusion. This eliminates the need for diagonal pulling and prevents suture entrapment

AI summary
Provided herein is a medical suture package that enables a medical suture to be wound therearound, stored therein, and carried, and which allows the suture to be drawn out when needed. The medical suture package is configured such that, when the suture is drawn out, friction between the suture and a main body of the package can be reduced, thus preventing a curling phenomenon, and making the operation of drawing out the suture easy. Particularly, even if external force is applied to the main body, a winding depression that is formed in the main body and in which the suture is wound around the main body can be maintained in shape, thus ensuring ease of the drawing-out of the suture, thereby markedly enhancing convenience in use.
