Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ultrasonic probes face low detection efficiency during intracavitary procedures due to the inability to simultaneously present the position of a puncture needle and punctured tissue in the ultrasonic image, requiring frequent probe movement to determine these positions.
Innovation Solution
An ultrasonic probe design featuring two convex arrays arranged in a first direction with a linear array perpendicular to them, allowing simultaneous coronal and sagittal plane imaging, enabling simultaneous observation of punctured tissue and puncture needle positions without probe movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a conventional single-array ultrasonic probe is used, then the device structure remains simple, but the positions of puncture needle and punctured tissue cannot be simultaneously presented in the ultrasonic image
Solution Approach 1:
The patent combines multiple ultrasonic array types (convex arrays and linear array) into a single transducer assembly, merging their imaging capabilities to simultaneously capture both coronal and sagittal plane information. This allows the puncture needle position and punctured tissue position to be presented together in one ultrasonic image, resolving the information loss problem without requiring separate probes or sequential imaging.
Solution Approach 2:
The patent introduces multi-dimensional imaging capability by arranging convex arrays and linear arrays in specific spatial configurations. The convex arrays provide coronal plane imaging while the linear array provides sagittal plane imaging, creating a three-dimensional imaging space that allows simultaneous visualization of needle and tissue positions from different anatomical perspectives.
2Productivity
If the probe is frequently moved to determine positions, then single-array simplicity is maintained, but detection efficiency decreases
Solution Approach 1:
By merging multiple array types into one integrated transducer assembly, the system eliminates the need to physically move or switch between different probe configurations. The combined arrays simultaneously capture multiple imaging planes, allowing doctors to obtain complete positional information without frequent probe repositioning, thus improving detection efficiency while maintaining operational simplicity.
Solution Approach 2:
The multi-array transducer assembly enables continuous simultaneous imaging of multiple planes (coronal and sagittal) during the puncture procedure. This continuous multi-planar imaging capability eliminates interruptions caused by probe movement, maintaining uninterrupted detection of both needle and tissue positions throughout the procedure.
3Measurement precision
If two convex arrays and a linear array are integrated, then simultaneous imaging of punctured tissue and puncture needle is achieved, but transducer assembly complexity increases
Solution Approach 1:
The transducer assembly is segmented into functionally distinct components: two convex arrays for coronal plane imaging and one linear array for sagittal plane imaging. Each array type is optimized for its specific imaging function, and their coordinated arrangement enables precise simultaneous positioning of the needle and tissue without requiring a single overly complex array design.
Solution Approach 2:
The integrated transducer assembly performs multiple imaging functions simultaneously - the convex arrays provide coronal plane imaging while the linear array provides sagittal plane imaging. This multi-functionality allows a single device to deliver comprehensive positional information that would otherwise require multiple separate imaging systems, justifying the increased structural complexity through enhanced measurement precision.

AI summary
The present disclosure relates to an ultrasonic probe and an ultrasonic device. The ultrasonic probe includes a linear array and two convex arrays arranged on both sides of the linear array in a first direction. An inner wall of a cavity and tissues close to the inner wall of the cavity are detected by the convex arrays to obtain a coronal plane image. A position of a puncture needle can be detected by the linear array to obtain a sagittal plane image. The convex arrays and the linear array transmit and receive ultrasonic waves simultaneously during use, so that the positions of the punctured tissue and the tip of the puncture needle can be observed simultaneously, without the need for frequently moving the ultrasonic probe to switch between two planes, thereby accurately achieving the intracavitary puncture operation and improving the detection accuracy and efficiency.
