Visual Puncture Apparatus with Integrated Imaging for Accurate Targeting
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 which can damage tissues or blood vessels.
Innovation Solution
A medical device with a visual puncture apparatus that integrates an imaging assembly within a puncture needle, allowing for real-time visualization of the puncture path, combined with ultrasound guidance, and a working channel for simultaneous use of additional instruments or therapies, such as lasers and suction, with detachable components for sterilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If ultrasound guidance is used for puncture, then the puncture procedure can be performed, but accurate positioning of the target is difficult requiring multiple punctures
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, enabling accurate one-step puncture without requiring multiple attempts.
Solution Approach 2:
The patent introduces an optical imaging waveguide as an intermediary component that transmits visual information from the puncture tip to the operator's eye or display device. This waveguide enables direct optical observation of the puncture path, serving as a mediator between the needle tip and the observer.
2Object-affected harmful factors
If traditional puncture without direct observation is used, then the procedure is simpler, but tissue or blood vessel damage occurs
Solution Approach 1:
The patent merges the puncture needle with integrated imaging capabilities (optical waveguide and/or ultrasound transducer), combining the therapeutic puncture function with the diagnostic imaging function into a single device, thereby enabling direct observation to prevent tissue damage.
Solution Approach 2:
The patent replaces traditional mechanical blind puncture methods with optical or acoustic imaging-based visualization methods. Instead of relying solely on anatomical knowledge and tactile feedback, the system uses light or sound waves to provide real-time visual feedback of the puncture path.
3Reliability
If multiple punctures are performed to achieve accurate positioning, then the target can be reached, but trauma increases and recovery is delayed
Solution Approach 1:
The patent integrates imaging functionality into the puncture needle itself, allowing the operator to visualize the puncture path and target in real-time. This enables accurate target acquisition in a single puncture, eliminating the need for multiple punctures and thereby reducing surgical trauma.
4Adaptability or versatility
If a reaming cannula is used to enlarge the wound after puncture, then instruments can be inserted, but the wound size increases
Solution Approach 1:
The patent designs the puncture needle with a through-hole that serves multiple functions: it guides the puncture path, allows optical imaging transmission, and enables insertion of additional instruments or therapies (such as lasers) without requiring a separate reaming cannula to enlarge the wound.
