Abstract

The invention discloses a synchronous fixed-point endocardial and epicardial mapping electrode, and belongs to the technical field of medical instruments. The mapping electrode comprises an epicardial electrode, an endocardial electrode, an electrode support, a stainless steel hollow column and a stainless steel pipe; the epicardial electrode and the endocardial electrode are used for recording electrical signals of an epicardium and electrical signals of an endocardium respectively; the electrode support is used for fixing the epicardial electrode and the endocardial electrode; the epicardial electrode is installed in an electrode channel formed in the electrode support in a penetrating mode, and an epicardial electrode contact is embedded into the tail end of the electrode channel; a square-column-shaped channel is formed in the electrode support, the stainless steel hollow column is arranged in the square-column-shaped channel, and the stainless steel pipe is connected to the tail end of the square-column-shaped channel; an endocardial electrode contact stretches out of the tail end of the stainless steel pipe and is cladded with a polytetrafluoroethylene material. The electrophysiological mapping electrode can synchronously record the electrical signals of the epicardium and the endocardium.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an endocardial synchronous fixed-point mapping electrode, which is an electrode device for recording cardiac electrical signals, especially an electrophysiological mapping electrode capable of synchronously recording endocardial electrical signals. Background technique [0002] At present, electrophysiological mapping electrodes commonly used in medicine can only be used to record electrophysiological signals of the endocardium, called electrode catheters, which are sent into the cardiac chamber through arterial and / or venous puncture for endocardial electrophysiological mapping. The lumen is solid and relatively soft, and the distal end of the metal guide wire is connected to the electrode, and the proximal end is a catheter plug, which can be inserted into the connection converter of the multi-channel physiological instrument. However, in the maze operation of atrial fi...
