Visible Puncture Device Balloon Channel Creation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional devices for visible puncture are time-consuming, inefficient, and costly due to the complexity of operations involving multiple steps and consumable item usage.
Innovation Solution
A device comprising a balloon, canula, needle tube, image acquisition device, and fluid injection tube, where the balloon is filled with fluid to expand and create a channel, allowing for clear visualization and simplified puncture and expansion procedures without the need for guide wire stabilization and sheath expansion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional puncture device is used with multiple steps (needle withdrawal, guide wire stabilization, sheath expansion), then puncture channel can be created, but operation time is excessive and procedure is complex
Solution Approach 1:
The patent combines the needle tube, balloon, and sheath into a single integrated puncture device. The needle tube and sheath are coaxially arranged with the balloon positioned between them, allowing all components to be inserted through one puncture action. This eliminates the need for separate needle withdrawal, guide wire stabilization, and sheath expansion steps, directly resolving the contradiction between operation efficiency and procedure complexity.
Solution Approach 2:
The balloon is pre-positioned on the needle tube before insertion. Upon reaching the target location, the balloon is inflated to expand the sheath and create the puncture channel in advance. This preliminary positioning and expansion action eliminates the need for subsequent stabilization steps, improving operational efficiency while maintaining device simplicity.
2Reliability
If multiple consumable items are used in conventional puncture procedure, then puncture operation can be completed, but cost increases
Solution Approach 1:
The integration of needle tube, balloon, and sheath into one device reduces the number of separate consumable items needed. The single integrated device performs all functions (puncture, expansion, channel creation) that previously required multiple separate components, thereby reducing consumable usage while maintaining reliable puncture outcomes.
3Ease of operation
If conventional step-by-step puncture procedure is followed, then channel can be created, but patient discomfort and surgical risks increase
Solution Approach 1:
The single integrated device performs puncture and channel creation in one continuous action, reducing the number of manipulations and interventions required. This simplifies the procedure and minimizes patient discomfort and surgical risks associated with multiple separate steps.
Solution Approach 2:
The balloon is pre-positioned and rapidly inflated to create the puncture channel in one action, eliminating prolonged manipulation and reducing the time the patient is exposed to surgical risks. The preliminary positioning ensures accurate channel creation without repeated adjustments.
