Solution Overview
Problem
Existing ultrasonic treatment instruments face challenges in effectively attenuating transverse vibrations, leading to abnormal noise and reduced efficiency due to the alignment of central axes of the vibration transmitter and tubular portion.
Innovation Solution
The ultrasonic treatment instrument employs a vibration transmitter main body with a support structure that elastically deforms within a tubular portion, aligning central axes to attenuate transverse vibrations by applying external forces along the curved direction of the treatment portion, using supports and a partially bent sheath configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the central axes of the vibration transmitter and tubular portion are aligned, then the structure is simple and easy to manufacture, but transverse vibrations are not effectively attenuated leading to abnormal noise
Solution Approach 1:
The patent introduces asymmetric elements: a bent portion in the vibration transmitter shaft and an offset between the central axis of the vibration generation source and the central axis of the tubular portion. This asymmetric configuration creates intentional misalignment that generates external force to attenuate transverse vibrations, resolving the contradiction between structural simplicity and noise reduction.
Solution Approach 2:
The patent applies preliminary anti-action by pre-positioning the bent portion and offset central axes before operation. This pre-configured asymmetric structure proactively generates the necessary external force to counteract transverse vibrations before they can cause abnormal noise, rather than attempting to correct the issue during operation.
2Object-generated harmful factors
If external force is applied to elastically deform the vibration transmitter main body, then transverse vibrations are suppressed, but the device complexity increases due to support structures
Solution Approach 1:
The patent applies local quality by providing supports only at specific locations on the outer peripheral surface of the vibration transmitter main body rather than uniformly throughout. The bent portion is also localized rather than distributed. This targeted approach achieves effective vibration suppression while minimizing the addition of structural complexity.
Solution Approach 2:
The patent uses a bent portion with a curved shape in the vibration transmitter shaft. This curvature allows the structure to elastically deform and generate the necessary external force for vibration attenuation without requiring complex rigid support mechanisms, thereby reducing overall device complexity while maintaining effectiveness.
3Stability of the object's composition
If the vibration transmitter is rigidly fixed in the tubular portion, then structural stability is high, but transverse vibrations cannot be attenuated effectively
Solution Approach 1:
The patent transitions from a static rigid fixation to a dynamic configuration. The bent portion and offset central axes create a structure that naturally generates external force during operation, enabling the vibration transmitter to elastically deform and attenuate transverse vibrations while maintaining structural stability through the tubular portion's constraints.

Function Achieved in This Case
This design effectively suppresses transverse vibrations, enhancing the efficiency and reducing abnormal noise by aligning central axes and applying external forces to the vibration transmitter, thereby improving the ultrasonic treatment process.
Implementation Method 1
a vibration generation source configured to generate ultrasonic vibration is connected to a proximal end of a vibration transmitter main body, the vibration transmitter main body transmitting ultrasonic vibration from the proximal end toward a distal end
Implementation Method 2
the vibration transmitter main body being disposed inside the tubular portion in a state of being elastically deformed by an external force that is generated by positioning the tubular portion in a state where a central axis of the vibration generation source and a central axis of the tubular portion are shifted from each other

AI summary
An ultrasonic treatment instrument includes: a vibration transmitter main body having a proximal end to which a vibration generation source is connected; a first support in which a central axis of an outer peripheral surface of the first support is shifted from a central axis of an inner peripheral surface of the first support when an external force is not applied; a second support in which a central axis of an outer peripheral surface of second support coincides with a central axis of an inner peripheral surface of second support when the external force is not applied; and a tubular portion into which the vibration transmitter is inserted and which has an inner peripheral surface on which the first support and the second support abut.
