The magnetic navigation apparatus is configured to navigate a positioning medical tool to a lesion region on the medical path. The optical positioning apparatus comprises an imaging module and at least three first markers provided on the medical image apparatus. The optical positioning apparatus is configured to acquire the position of the medical image apparatus relative to the imaging module. The medical image apparatus is configured to move according to the position of the medical image apparatus relative to the imaging module to scan a head end region of the positioning medical tool to acquire an image, and reconstruct a two-dimensional image and/or a three-dimensional model of the head end region of the positioning medical tool.

Abstract: A medical system, comprises an operation table, a magnetic navigation apparatus and a medical image apparatus. The magnetic navigation apparatus and the medical image apparatus are respectively provided beside the operation table, and the operation table can be transmitted by rays of the medical image apparatus. The magnetic navigation apparatus is configured to navigate, according to a medical path, a positioning medical tool to a lesion region on the medical path. The medical image apparatus is configured to scan a head end region of the positioning medical tool to acquire a medical image, and to reconstruct a two-dimensional image and/or a three-dimensional model of the head end region of the positioning medical tool, so as to confirm the surrounding condition of the positioning medical tool and whether the positioning medical tool reaches a correct position.

Abstract: Embodiments of the present application provide a radiofrequency ablation catheter and a radiofrequency ablation system. The radiofrequency ablation catheter includes: a catheter body; a ring electrode, annularly provided at a head of the catheter body; a location sensor, provided in the catheter body; and an ablation needle, provided in the catheter body and capable of moving forward or backward. The ablation needle, when applied, pushes out from the head of the catheter body and penetrates into a lesion tissue. The embodiments of the disclosure enable an accurate location of the lesion position and the puncture into lesion for performing radiofrequency ablation therapy, so as to achieve the targeted precise ablation therapy and reduce the damage to normal tissues.

Abstract: Embodiments of the present application disclose a radiofrequency ablation catheter and a system. The radiofrequency ablation catheter includes: a catheter body; a localization sensor fixedly arranged inside the catheter body; and ablation electrodes fixedly arranged on the outer surface of the catheter body and used for generating radiofrequency currents, wherein the localization sensor generates a current signal in response to a localization magnetic field of a space where the localization sensor is located, and outputs the current signal to a control system outside the radiofrequency ablation catheter, so as to enable the control system to determine a position of the radiofrequency ablation catheter. The radiofrequency ablation catheter and system provided by the embodiments of the present application may help the ablation electrodes to be placed in the lesion positions more accurately.

Abstract: A medical path navigation method, planning method and device are provided. The navigation method includes: planning a navigation path; delivering an ablation catheter with a localization sensor into an airway leading to a lesion region according to the navigation path; adjusting a position and a direction of the ablation catheter in the airway based on the localization sensor during a moving process of the ablation catheter in the airway until the ablation catheter is navigated to a planned initial ablation region; and adjusting a position and a direction of the ablation catheter in the lesion region based on the localization sensor during a moving process of the ablation catheter in the lesion region until the ablation catheter is navigated to other ablation regions, thereby accurately navigating the ablation catheter to a lesion position that is not reachable by a bronchoscope.
