Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ultrasonic vibration transmittable probes face challenges in efficiently forming precise holes in bone tissue with existing cutting surfaces, leading to inefficiencies in surgical procedures such as forming bone sockets for ligament reconstruction.
Innovation Solution
The ultrasonic vibration transmittable probe features a treatment section with progressively positioned cutting surfaces, including first to third cutting surfaces, where the first surface has a smaller dimension orthogonal to the longitudinal axis, allowing for precise bone cutting and efficient debris discharge, enhancing the formation of concave bone sockets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional cutting surfaces are used in ultrasonic probes, then bone cutting can be performed, but the formation of precise bone sockets is inefficient and debris accumulation occurs
Solution Approach 1:
The treatment section is divided into multiple cutting surfaces (first, second, and third cutting surfaces) positioned at different locations along the longitudinal axis. Each cutting surface contributes to different aspects of bone socket formation, enabling simultaneous precision and efficiency through segmented functional zones
Solution Approach 2:
The cutting surfaces are arranged in a stepped configuration along the longitudinal axis, creating a three-dimensional progressive structure. This dimensional arrangement allows debris to be discharged along the longitudinal axis while maintaining precise cutting at each level, resolving the contradiction between precision and debris accumulation
2Manufacturing precision
If the first cutting surface has a smaller dimension orthogonal to the longitudinal axis, then precise bone cutting is achieved, but the area for debris discharge is reduced
Solution Approach 1:
The cutting function is segmented across three distinct surfaces positioned at different longitudinal locations. The first cutting surface with smaller orthogonal dimension provides precision cutting, while the second and third cutting surfaces with larger dimensions provide additional cutting capability and create pathways for debris discharge along the longitudinal axis
Solution Approach 2:
By arranging cutting surfaces at progressively proximal positions along the longitudinal axis with varying orthogonal dimensions, the design utilizes the longitudinal dimension to resolve the conflict between precision (smaller orthogonal dimension) and debris discharge (larger overall structure). Debris can escape through the stepped configuration along the length of the probe

AI summary
An ultrasonic vibration transmittable probe includes a probe body configured to transmit ultrasonic vibration generated by an ultrasonic transducer. A treatment section is provided on a distal end side of the probe body along its longitudinal axis and is configured to cut a treatment object with the ultrasonic vibration. The treatment section includes first to third cutting surfaces disposed at progressively proximal positions. A portion of the first cutting surface has a dimension along a first orthogonal direction orthogonal to the longitudinal axis that is smaller than a dimension of the second cutting surface along the first orthogonal direction.
