Syringe Rotatable Element for Biopsy Aspiration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional syringes lack efficient mechanisms for rotating elements, requiring costly and complex connections between the syringe barrel and aspiration elements, limiting their usability in procedures like biopsy and fluid mixing.
Innovation Solution
A syringe design featuring a rotatable element, such as a slip ring, that can rotate relative to the barrel and handle, allowing the barrel to remain stationary or rotate freely, eliminating the need for costly rotatable connections and enabling use in various medical procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional syringes use fixed connections between barrel and aspiration elements, then structural simplicity is maintained, but rotation capability is limited and costly complex connections are required
Solution Approach 1:
The patent applies the dynamics principle by introducing a rotatable element that can rotate relative to the syringe barrel. This dynamic component allows the aspiration element to rotate freely without requiring complex fixed connections, thereby improving adaptability while maintaining connection simplicity.
Solution Approach 2:
The patent segments the syringe system into distinct rotatable and stationary components. The rotatable element is separated from the barrel, allowing independent rotation capability. This segmentation enables rotation functionality without requiring the entire connection structure to be complex and rotatable.
2Adaptability or versatility
If a rotatable element is added to enable rotation, then adaptability and rotation capability are improved, but device complexity increases
Solution Approach 1:
The rotatable element introduces dynamic capability to the syringe system, enabling rotation of the aspiration element relative to the barrel. This single dynamic component provides the required adaptability without necessitating multiple complex mechanisms throughout the structure.
Solution Approach 2:
The rotatable element acts as an intermediary component between the stationary barrel and the aspiration element. It mediates the rotation function, allowing the aspiration element to rotate while the barrel remains stable, thereby adding functionality with minimal structural complexity.
3Adaptability or versatility
If costly rotatable connections are used between barrel and aspiration element, then rotation capability is achieved, but manufacturing cost increases
Solution Approach 1:
The rotatable element provides the necessary rotation capability through a simple dynamic design rather than expensive complex rotatable connections. This approach achieves the required adaptability while maintaining ease of manufacture and reducing costs.
Solution Approach 2:
The rotatable element can be implemented as a simple, potentially disposable component that enables rotation without the need for expensive, complex, and durable rotatable connections. This reduces manufacturing costs while maintaining the required functionality.

AI summary
A syringe includes a barrel and a rotatable element on the barrel, for example, at a proximal location along the length of the barrel. The rotatable element rotates at least partially around the barrel. When a handle is associated with the rotatable element, the barrel may rotate as the handle is held substantially stationary or the handle may be rotated while the barrel and any peripheral device secured thereto remain substantially stationary. When handles are associated with a rotatable element that may be removed from a barrel, a barrel that is disassembled from the rotatable element may be replaced with another barrel of the same or a different configuration. The barrel and plunger may be configured to cause the barrel to rotate as the plunger moves along the length of the barrel. Methods of using a syringe with a rotatable element on a barrel thereof are also disclosed.
