Abstract

The invention discloses a device and method for detecting the falling off of the surface excitation electrode sheets of a three-dimensional mapping system. With the device and method adopted, the accurate monitoring of the surface excitation electrode sheets can be realized stably and accurately, and an alarm can be issued in time when the surface excitation electrode sheets fall off. The device comprises a falling-off signal detecting circuit, a falling-off signal processing module, and a human-computer interaction interface; the falling-off signal detecting circuit is connected with the excitation source of the three-dimensional navigation system and is used for collecting falling-off signals from excitation current; and the falling-off signal processing module is connected with the falling-off signal detecting circuit so as to receive the falling-off signals, is connected with the excitation switching controller of the three-dimensional navigation system so as to receive synchronization signals, and is used for generating a falling-off alarm according to the falling-off signals and the synchronization signals; and the human-machine interaction interface performs falling-off alarm prompting.

Description

technical field [0001] The invention relates to the technical field of three-dimensional mapping, in particular to a device and method for detecting the detachment of a body surface excitation electrode sheet in a three-dimensional mapping system. Background technique [0002] The three-dimensional cardiac mapping system belongs to the electrocardiographic medical equipment. The purpose is to establish a three-dimensional model of the heart during catheter-based cardiac surgery, and at the same time display the position of the catheter in real time, which is convenient for doctors to perform operations. The system includes a constant current excitation source, which generates three sinusoidal signals in time division, and outputs them to three pairs of body surface excitation electrodes, forming an orthogonal electric field in the human body. The three-dimensional positioning is to use the electrodes of the catheter to collect the excitation signal, and after the system proc...
