Ultrasonic Probe Marking Light for Hands-Free Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ultrasonic detection devices are cumbersome and require both hands for operation, making it difficult to perform additional tasks like infusion or carotid puncture during detection due to the need to view the screen and the detection surface simultaneously, resulting in a low success rate.
Innovation Solution
An ultrasonic detection system with a marking light at the ultrasonic probe that indicates the marking position on the detected object's surface, allowing operators to input marks on an ultrasonic image, determine the marking position, and transmit this information for accurate positioning, enabling hands-free operation and improved success rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a hand-held ultrasonic detection device with separated hand-held end and processing end is used, then the device can be held by hand for detection, but both hands are required to hold the processing end with screen and the ultrasonic hand-held end, leaving no free hand for additional operations
Solution Approach 1:
A marking light is introduced as an intermediary device between the ultrasonic probe and the operator's eye. The marking light projects the detection position information directly onto the detected object's surface, serving as a mediator that eliminates the need for the operator to simultaneously view the screen and the detection surface, thereby freeing the hand for additional operations
Solution Approach 2:
The patent replaces the mechanical system of using both hands to hold the device and viewing the screen with an optical system. The marking light uses optical projection to display position information directly on the object surface, substituting the mechanical hand-holding and visual screening process with an optical projection mechanism that frees the operator's hand
2Measurement precision
If the operator views the ultrasonic display image to determine the operating position, then detection accuracy is maintained, but the operator cannot simultaneously view the detection surface, resulting in low operation success rate
Solution Approach 1:
The marking light creates a visual copy of the detection position information directly on the object's surface. Instead of relying on the operator to interpret the ultrasonic image on the screen and mentally translate it to the physical detection surface, the system projects a direct visual copy of the position information onto the object, eliminating the translation error and improving operation success rate while maintaining detection accuracy
3Adaptability or versatility
If the ultrasonic probe is moved to different positions for detection, then comprehensive detection is achieved, but the marking light position does not accurately reflect the current detection position, reducing operational accuracy
Solution Approach 1:
The system implements a feedback mechanism where the marking light position is dynamically updated based on the real-time position of the ultrasonic probe. As the probe moves to different detection positions, the marking light automatically adjusts its projection position to reflect the current detection location, ensuring continuous accuracy throughout the detection process and enabling comprehensive detection coverage
