Abstract

The invention relates to a tissue ablation, cutting and fusion system, which comprises a handle assembly, a shaft assembly, a working part, a circuit system and a power supply. The handle assembly comprises a source handle and a passive handle; the active handle and the passive handle are connected together through a shaft assembly. The active handle comprises a gear adjusting mechanism, a circuit plugging mechanism and a shell. The gear adjusting mechanism is arranged on the shell; and the circuit plugging mechanism can realize the separation and connection of circuit systems at the far end and the near end of the active handle. The far end of the active handle and the passive handle are connected into a whole through the shaft assembly, and the detachable working end of the tissue ablation, cutting and fusion system is formed. Due to the fact that the detachable working end only comprises the electric heating device and a circuit and does not comprise electronic components such as a capacitor, and electronic components such as a controller and an electric interface device are all arranged at the near end, the sterilization process is safer, and the manufacturing cost of the detachable working end is lower.

Description

technical field [0001] The invention relates to an electrosurgical instrument, in particular to the surgical instrument used for tissue ablation, cutting and fusion in surgical operations. Background technique [0002] In surgery, tissue ablation, cutting and fusion are very important tissue processing processes. Among the commonly used tissue ablation, cutting and fusion technologies, electric heating tissue ablation method is one of the important technologies. By heating the tissue, causing Modification of proteins to enable tissue ablation, cleavage and fusion processes. [0003] In the prior art tissue ablation, cutting and fusion systems, since the working part needs to be heated, a heating system and corresponding electronic and circuit systems need to be designed in the working part. The working part is a part in direct contact with human tissue, therefore, it must be aseptically treated. [0004] Ethylene oxide sterilization is currently the most widely used and mo...
