Ultrasonic Probe Insulation Layer Vibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In ultrasonic treatment apparatuses, the conductive portion does not vibrate due to lack of ultrasonic vibration transmission, leading to treatment object adhesion and reduced performance.
Innovation Solution
An ultrasonic probe with an insulation layer and two electrode portions, where the insulation layer covers the probe main body and extends beyond the treatment section, ensuring both electrodes vibrate with the probe and are exposed only in specific areas to prevent adhesion and enhance treatment performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the conductive portion is provided as one of the two electrodes in bipolar treatment, then the electrode structure is established for high-frequency treatment, but the treatment object adheres to the conductive portion due to lack of ultrasonic vibration
Solution Approach 1:
The conductive portion is divided into multiple independent conductive sections along the longitudinal direction, with insulation portions between them. This segmentation allows different conductive sections to have different vibration characteristics, preventing uniform adhesion of the treatment object to the entire conductive portion while maintaining the electrode structure for high-frequency treatment
Solution Approach 2:
Different sections of the conductive portion are designed with different properties - some sections are made non-vibrating (fixed to the probe body) while others are made vibrating (exposed in the treatment section). This local differentiation ensures that the treatment object adheres to vibrating sections for effective treatment while non-vibrating sections provide stable electrical contact
2Stability of the object's composition
If the conductive portion is made non-vibrating to maintain structural stability, then the electrode function is ensured, but the treatment object adheres to it reducing treatment effectiveness
Solution Approach 1:
The conductive portion is segmented into multiple conductive sections separated by insulation portions. This segmentation creates zones with different vibration characteristics along the longitudinal axis, allowing the treatment object to adhere only to vibrating sections while non-vibrating sections maintain structural stability and provide stable electrical contact
Solution Approach 2:
Insulation portions are introduced as intermediary elements between conductive sections. These insulation portions prevent direct electrical contact between adjacent conductive sections while allowing the treatment object to interact with vibrating conductive sections, thus mediating between the need for structural stability and prevention of harmful adhesion

AI summary
In an ultrasonic probe, an insulation layer portion is formed on an outer surface of a probe main body portion. A first electrode portion provided on an outer surface of the insulation layer portion so that at least part of the first electrode portion is exposed to an outside in a treatment section, and at least part of a second electrode portion is exposed to the outside in the treatment section. The second electrode portion is electrically insulated from the first electrode portion by the insulation layer portion. The probe main body portion vibrates integrally with the insulation layer portion, the first electrode portion and the second electrode portion.
