Curved Biopsy Needle Module With Integrated Guide for Faster Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional biopsy needle devices require significant assembly time due to the need for separate components like guide inner and guide outer, and the omission of these components leads to inefficiencies in the biopsy procedure.
Innovation Solution
A biopsy needle module with an integrated needle unit, needle curving frame, and needle guide that allows for easy assembly by sliding the needle guide along the curved rail, eliminating the need for separate straighteners and reducing assembly time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If separate guide inner and guide outer components are used to curve the needle, then the needle can be properly positioned and curved for biopsy, but the assembly time increases significantly
Solution Approach 1:
The patent combines the previously separate guide inner and guide outer components into a single integrated guide structure. This integration maintains the curved positioning functionality while eliminating the time-consuming assembly process of fitting multiple separate components together.
Solution Approach 2:
The needle assembly is divided into modular components (needle, guide structure, straightener) that can be independently manufactured and then quickly assembled through simple attachment mechanisms, reducing the complexity and time of assembly while maintaining precision.
2Adaptability or versatility
If multiple components (guide outer, guide inner, straightener) are assembled separately, then each component can be optimized for its specific function, but the overall device complexity and assembly time increase
Solution Approach 1:
The guide outer and guide inner are merged into a single integrated guide structure that provides both guiding and curving functions, reducing the number of components and assembly steps while maintaining the specialized functionality needed for precise needle positioning.
Solution Approach 2:
The integrated guide structure performs multiple functions (guiding the needle, curving it to the target position, and maintaining stability) that were previously distributed across multiple separate components, simplifying the overall device while preserving adaptability.
3Strength
If the needle is stored in a straight form, then it maintains rigidity and structural integrity, but it cannot be inserted into the patient's tissue in the required curved path through the narrow gantry space
Solution Approach 1:
The needle is designed with a curved configuration that allows it to navigate the narrow gantry space and reach the target tissue through a curved path. The curvature is maintained through the integrated guide structure while the needle material provides sufficient rigidity to maintain its shape during insertion and biopsy procedures.

Function Achieved in This Case
The integrated design significantly reduces assembly time and enhances precision by allowing for more efficient manipulation of the needle unit, improving the biopsy procedure's efficiency and accuracy.
Implementation Method 1
The needle 31 used in the biopsy needle device 30 is made of a highly rigid superelastic material that has superelasticity when being bent and recovers rigidity in a straight part

AI summary
The present invention relates to a biopsy needle module using medical imaging equipment, the biopsy needle module being inserted into a biopsy area of a patient to do a biopsy. The biopsy needle module comprises: a needle part (110), made of high-strength and super-elastic material, having overlapping inner needle (113) and outer needle (111); a curved needle frame (120) curving in a perpendicular direction and having, in the front, a needle front end-exposing hole (123a) through which the front end of the needle part (110) is exposed to the outside, and, in the rear, a curved rail (125) that is open along the curved surface; and a needle guide (130), coupled so as to slide along the curved rail (125) of the curved needle frame (120), for supporting, in a straight line, the back end of the needle part (110) the front end of which is inserted in the needle front end-exposing hole (123a), and guiding the needle part (110), in a curved state, in moving forward and backward along the curved needle frame (120).
