Seeing Puncture Needle with Integrated Optical System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional puncture needle systems for kidney stones lack precision in accessing the correct position, leading to potential damage to vessels or the intestine during minimally invasive procedures, and do not allow for real-time quality assessment of the access channel without the use of locating aids like X-ray or ultrasound.
Innovation Solution
A 'seeing puncture needle' system with a working shaft and integrated optical system allows for precise positioning and real-time visualization of the puncture needle's placement, enabling accurate access to kidney stones and avoiding accidental damage to surrounding tissues, and can be used with various lithotripsy devices or endoscopes for stone fragmentation and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional puncture needle systems are used without integrated optics, then the device structure remains simple, but the positioning precision and ability to avoid vessels or intestine is insufficient
Solution Approach 1:
The patent combines the puncture needle function with an integrated optical system into a single device. The optical system is inserted through the working shaft of the puncture needle, allowing simultaneous puncture and visualization functions without requiring separate locating aids, thereby improving positioning precision while maintaining relatively simple device structure
Solution Approach 2:
The puncture needle system is designed to perform multiple functions: puncturing the skin, visualizing the puncture path through the optical system, and avoiding critical structures like vessels or intestine. This multi-functional design eliminates the need for separate locating aids and improves overall procedural precision
2Measurement precision
If locating aids like X-ray or ultrasound are used to check puncture needle position, then measurement precision is improved, but the procedure complexity and time increase
Solution Approach 1:
The patent extracts the visualization function from external locating aids (X-ray, ultrasound) and integrates it directly into the puncture needle through an embedded optical system. This allows real-time visualization of the puncture path without requiring separate imaging equipment, thereby improving access quality assessment while reducing procedure complexity
Solution Approach 2:
The optical system acts as an intermediary that provides direct visual feedback of the puncture path and surrounding tissues. This intermediary visualization capability eliminates the need for complex external imaging systems and allows real-time assessment of access quality during the puncture procedure
3Object-affected harmful factors
If the puncture needle is made thin for minimal invasiveness, then patient trauma is reduced, but the structural stability and ability to support lithotripsy devices decreases
Solution Approach 1:
The puncture needle system is segmented into multiple functional components: a thin puncture needle for minimal trauma, a working shaft for structural support, and an optical system for visualization. This segmentation allows the thin needle to perform its function while the thicker working shaft provides the necessary structural stability to support lithotripsy devices
