Transperineal Puncture Guiding Bracket With Detachable Needle Plates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transperineal puncture guiding brackets are limited by integrated needle grooved plates, requiring different brackets for different biopsy needle specifications and hindering flexible operation due to non-separable needle hole structures.
Innovation Solution
A transperineal puncture guiding bracket with a detachable guiding assembly comprising a probe fixing assembly and a guiding assembly, featuring vertically distributed needle guiding holes, allowing for interchangeable needle grooved plates and cover plates through detachable vertical insertion, hanging, and buckling structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a closed needle hole structure is used for guiding biopsy needles, then the puncture guiding bracket provides stable guidance, but the bracket cannot be separated from the biopsy needle which limits flexible operation
Solution Approach 1:
The puncture guiding bracket is divided into separable components: the bracket body and the needle grooved plate. The needle grooved plate can be detached from the bracket body, allowing the biopsy needle to be separated into two parts (needle body and needle hole cover). This segmentation enables flexible operation while maintaining stable guidance when assembled.
Solution Approach 2:
The design transitions from a static integrated structure to a dynamic separable structure. The needle grooved plate can be dynamically attached or detached from the bracket body according to surgical needs, providing both stability during puncture and flexibility during operation.
2Device complexity
If the needle grooved plate and bracket body are integrated to form a whole structure, then the structure is simple and stable, but different puncture guiding brackets are required for biopsy needles of different specifications which brings inconvenience
Solution Approach 1:
The needle grooved plate is designed as a separate module that can be detached from the bracket body. Different needle grooved plates with varying hole specifications can be interchangeably mounted on the same bracket body, eliminating the need for multiple complete brackets for different needle sizes.
Solution Approach 2:
The bracket body is designed as a universal base that can accommodate multiple types of needle grooved plates. This multi-functionality allows a single bracket body to serve with different biopsy needle specifications, improving adaptability while maintaining structural simplicity.
