Abstract

The invention provides transcatheter navigation processing method, device, medium, equipment and navigation system. According to the invention, N sensors are arranged on one catheter, and sequentially distributed at different positions in the length direction of the catheter. The transcatheter navigation processing method comprises the following steps: acquiring actual detection information of the N sensors after the catheter enters a physiological conduit to be detected; determining the current curvature information of the catheter according to the detection information of the N sensors; characterizing the current curvature of at least part of catheter sections in the catheter on basis of the current curvature information; at least part of the conduit section is matched with the distribution positions of the N sensors; and then, determining the position of the catheter in the to-be-detected physiological pipeline according to the current curvature information and reference curvature information, wherein the reference curvature information represents the curvature of each pipeline section in the to-be-detected physiological pipeline.

Description

technical field [0001] The present invention relates to the field of medical devices, in particular to a catheter-based navigation processing method, device, medium, equipment and navigation system. Background technique [0002] In medical activities, it is necessary to introduce catheters into the physiological channels of animals or human bodies, and then, it can facilitate the realization of endoscopy, biopsy and other processes. After the catheter enters the physiological conduit, it is often necessary to navigate the position of the catheter within the physiological conduit. [0003] In the existing related technology, a sensor can be arranged on the catheter, and the movement trajectory of the sensor can be collected, and then the position of the catheter can be positioned through registration between the movement trajectory and the detection map of the physiological pipeline. However, in this process, it is difficult to accurately and effectively collect continuous m...
