Title:
TISSUE ABLATION, CUTTING AND FUSION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/011047
Kind Code:
A1
Abstract:
The tissue ablation, cutting and fusion system of the present invention comprises a handle assembly, a shaft assembly, a working portion, a circuit system, and a power source. The circuit system is provided with an elastic electrical interface device, and the elastic electrical interface device comprises a conductive joint, an elastic conductive mechanism and an electrical interface. The conductive joint comprises a rotor and a stator. When a shaft rod rotates, the rotor may rotate synchronously, and lines connecting the conductive joint and a rear end of the shaft rod are synchronized, which may prevent wire breakage or the loosening of solder joints that may be caused by the twisting of the lines. The elastic conductive mechanism is a conductive mechanism capable of elastically deforming under the action of an external force while keeping the circuit uninterrupted. When the shaft rod translates, the elastic conductive mechanism elastically deforms and moves reciprocatingly, thus overcoming fatigue breakage or the loosening of solder joints caused by the constant expansion and contraction of a wire during a current wire connection. The tissue ablation, cutting and fusion system of the present invention maintains good controllability of the device, and also improves the reliability of a circuit.
