Electrical pulse ablation apparatus for endoscope

Abstract

The invention relates to the technical field of pulse ablation, in particular to an electrical pulse ablation apparatus for an endoscope. The electrical pulse ablation apparatus comprises an electrodeassembly, a pulse waveform generator, an electrode driving device, parameter input equipment and a control device, wherein the electrode assembly comprises a central pole and a tube pole, and is configured for passing through a working channel of the endoscope into the body and transmitting pulses to the tissue during use; the pulse waveform generator is coupled to the electrode assembly and usedfor transmitting pulse voltage to the electrode assembly; the electrode driving device is used for driving the central pole and the tube pole; the parameter input equipment is used for configuring coordinate information of an ablation area; the control device is in signal connection with the parameter input equipment and in control connection with the electrode driving device, and the control device controls the displacement of the central pole and tube pole according the preset coordinate information through the electrode driving device separately; when a discharging end of the electrode assembly reaches a preset position, the control device controls the connection of the pulse waveform generator and electrode assembly; a human body natural channel is used for conveying an electrode to acomplicated area of the human body for ablation, thereby reducing traumas to the human body.

Description

technical field [0001] The invention relates to the technical field of pulse ablation, in particular to an electric pulse ablation instrument for an endoscope. Background technique [0002] At present, the clinical treatment of tumors is mainly based on radical surgical resection, but for tumors located in densely ducted areas such as the pancreas, bile duct, and hepatic duct, the open surgery trauma is relatively large, and the wound healing time is long. During the wound healing period, the wound should not touch water. , will bring inconvenience to patients' daily life. [0003] The medical endoscope can enter the human body through the natural channel of the human body, or a small incision made through surgery, and check through the endoscope, which causes little trauma to the human body. Some endoscopes even have a working channel, which can carry special equipment and have multiple functions such as lighting, surgery, irrigation, and suction. This kind of endoscope wi...

Problems solved by technology

[0004] In addition, the existing ablation equipment using double-needle parallel electrodes has a fixed distance between the two electrodes and a fixed electric field. The electric field cannot be adjusted according to the ablation section of the tumor during the advancement of the electrodes, resulting in the need for multiple operations. Achieved effect, poor ablation effect
