Solution Overview
Problem
Existing ultrasonic operating apparatuses for tissue incision, removal, and coagulation lack efficient high-frequency electric path configurations, leading to complex wiring and reduced operational simplicity.
Innovation Solution
The apparatus incorporates a cylindrical casing with multiple electric path elements, including high-frequency and ultrasonic paths, integrated into the transducer unit and handle, allowing for simplified wiring and enhanced sterilization capabilities through reduced vapor density and improved assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate electric paths (high-frequency and ultrasonic) are provided in existing ultrasonic operating apparatuses, then each electric path can be independently configured, but the wiring becomes complex and the number of connecting cords increases
Solution Approach 1:
The patent combines multiple electric paths (high-frequency and ultrasonic) into a single integrated cable assembly. The cable contains multiple conductors that are bundled together, allowing both high-frequency current and ultrasonic power to be transmitted through one unified connection rather than requiring separate cables and connection points.
Solution Approach 2:
The integrated cable assembly serves multiple functions simultaneously: it transmits both high-frequency electrical current and ultrasonic power, provides mechanical coupling between the handpiece and power supply, and enables both types of treatments through a single connection interface.
2Reliability
If complex wiring configurations are used in existing apparatuses, then multiple electric paths can be maintained, but operational simplicity is reduced
Solution Approach 1:
The patent merges multiple connection operations into a single action. By integrating both high-frequency and ultrasonic electric paths into one cable assembly, the operator needs to make only one connection rather than managing multiple separate connections, thereby simplifying the operational procedure.
3Reliability
If traditional wiring arrangements are used, then electric paths can be established, but sterilization effectiveness is reduced due to vapor density issues
Solution Approach 1:
The patent extracts the electric paths from the main sterilizable assembly and places them in a separate cable that can be easily removed. This allows the handpiece and treatment components to be fully sterilized using autoclaving or other methods without concern for electrical components, while the cable can be separately disinfected or replaced.

Function Achieved in This Case
This configuration simplifies the wiring, enhances sterilization, and reduces the number of connecting cords, improving operational efficiency and ease of use while maintaining effective high-frequency and ultrasonic treatments.
Implementation Method 1
an ultrasonic transducer for generating ultrasonic vibrations is provided in this operation portion
Implementation Method 2
The proximal end of the vibration transmitting member is detachably connected to the ultrasonic transducer via a threaded joint. Thus, the ultrasonic vibrations generated by the ultrasonic transducer are transmitted to an ultrasonic probe
Implementation Method 3
A heat insulating antivibration layer is formed between the inner casing and the outer casing
Implementation Method 4
A heat insulating antivibration layer is formed between the inner casing and the outer casing
Implementation Method 5
An electric cord for supplying a high-frequency current from a high-frequency cauterization power supply unit is connected to the high-frequency connecting pin. The inner end of the high-frequency connecting pin is electrically connected to the ultrasonic probe of the treatment portion via the operation portion and via an electric conduction path within the sheath
