Visual Puncture Needle With Working-Channel Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing minimally invasive surgical procedures face challenges in accurately puncturing the target position due to the limitations of ultrasound technology, often requiring multiple punctures, causing increased trauma, delayed recovery, and potential infection, with traditional methods lacking direct observation of the puncture path that can damage tissues or blood vessels.
Innovation Solution
A medical device with a visual puncture apparatus incorporating a puncture needle, imaging assembly, and display device, enabling real-time image acquisition and display to guide precise puncture, and allowing simultaneous use of additional instruments or tools through a single working channel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If ultrasound technology is used for puncture guidance, then the puncture procedure can be performed, but accurate positioning of the target position cannot be achieved at one time
Solution Approach 1:
The patent combines ultrasound imaging capability directly with the puncture needle, merging the guidance function and the puncture function into a single integrated device. This allows real-time visualization of the puncture path and target position, enabling accurate one-time puncture without requiring multiple attempts.
Solution Approach 2:
The patent introduces an imaging assembly as an intermediary component that provides real-time visual feedback between the operator and the puncture target. This intermediary imaging system allows the operator to see the puncture path and adjust positioning before completing the puncture, thereby achieving accurate positioning in a single attempt.
2Measurement precision
If multiple punctures are performed to achieve accurate puncture, then the target position can be reached, but trauma to the patient increases
Solution Approach 1:
The patent enables preliminary visualization of the puncture path and target position through the integrated imaging assembly before the actual puncture is made. This preliminary observation allows the operator to plan and execute a single accurate puncture, avoiding the need for multiple puncture attempts that would increase patient trauma.
3Productivity
If traditional puncture method is used, then the procedure can be completed, but direct observation of the puncture path is not possible
Solution Approach 1:
The patent incorporates real-time imaging feedback through the imaging assembly that allows the operator to observe the puncture path as it is being created. This immediate feedback enables the operator to detect and correct potential damage to tissues or blood vessels during the puncture process, rather than discovering damage only after the procedure is complete.
4Device complexity
If a single working channel is used to accommodate imaging assembly and additional instruments, then device complexity is reduced, but space for additional instruments is limited
Solution Approach 1:
The patent designs the single working channel to serve multiple functions: accommodating the imaging assembly for visualization, allowing passage of additional diagnostic or therapeutic instruments, and providing a unified access path to the target position. This multi-functional design reduces overall device complexity while maintaining versatility through the ability to introduce different instruments through the same channel as needed.
