Ultrasonic Probe Curving Section for Narrow Cavity Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ultrasonic probes face challenges in effectively treating hard bone and cartilage tissues due to limitations in design, leading to inefficient cutting and potential damage to non-target areas in narrow cavities like the knee joint.
Innovation Solution
The ultrasonic probe features a curving section with a treating region and specific bending surfaces, allowing the blade tip portion to be positioned on the extension line or opposite to the longitudinal axis, enhancing insertion and treatment efficiency while preventing contact with non-target areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the ultrasonic probe uses a straight probe main body section, then the structure is simple and easy to manufacture, but the probe cannot effectively treat hard tissues in narrow cavities like the knee joint and may damage non-target areas
Solution Approach 1:
The probe main body section is designed with a curving section that has a central axis bending relative to the longitudinal axis, allowing the probe to navigate narrow cavities like the knee joint and accurately treat hard tissues without damaging surrounding areas
2Manufacturing precision
If the ultrasonic probe has a curving section with specific bending surfaces, then the treatment precision and ability to avoid non-target areas is improved, but the manufacturing complexity increases
Solution Approach 1:
The curving section is divided into multiple bending surfaces (first, second, third bending surfaces and treating surfaces) with specific geometric relationships, where each surface is positioned on extension lines of previous surfaces, enabling precise control of the blade tip position while maintaining manufacturing feasibility
Solution Approach 2:
The curving section introduces spatial dimensionality with multiple bending surfaces arranged in specific three-dimensional configurations, allowing the blade tip to be positioned on extension lines of bending surfaces to achieve precise treatment positioning
3Productivity
If the probe main body section is extended along the longitudinal axis, then the ultrasonic vibration transmission is efficient, but the probe cannot access narrow cavities effectively
Solution Approach 1:
The probe maintains longitudinal extension for efficient ultrasonic vibration transmission while incorporating a curving section with a central axis that bends relative to the longitudinal axis, enabling the probe to access narrow cavities like the knee joint

Function Achieved in This Case
This design improves the probe's ability to treat hard tissues within narrow cavities by enhancing insertion properties and treatment efficiency, reducing the risk of damaging non-target areas and preventing probe breakage due to stress concentration.
Implementation Method 1
an ultrasonic vibration generated in a vibration generating section (an ultrasonic vibration mechanism) is transmitted from a proximal toward a distal in the ultrasonic probe

AI summary
A curving section is always disposed in a projection plane of a probe main body section. The curving section includes a first bending surface which bends relative to a peripheral surface of the probe main body section to approach a longitudinal axis, thereby intersecting the longitudinal axis; a second bending surface which bends relative to the first bending surface toward a bending direction of the first bending surface and a direction away from the longitudinal axis; a third bending surface which bends relative to the second bending surface toward a direction to approach the longitudinal axis on a side reverse to the bending direction of the first bending surface, and extends toward an extension line of the first bending surface.
