Systemic heart electrophysiology stereo-positioning device

Abstract

The invention discloses a systemic heart electrophysiology stereo-positioning device which comprises a track fixed to a workbench. A track sliding block is arranged on the track. A horizontal rotating module is arranged on the track sliding block. A perpendicular lifting mechanism is arranged on the horizontal rotating module. The lifting end of the upper portion of the perpendicular lifting mechanism is connected with the right end of the transverse motion mechanism. The left end of the transverse motion mechanism is connected with an electrode lifting mechanism. The lifting portion of the electrode lifting mechanism is connected with an electrode perpendicular positioning rod. The lower end of the electrode perpendicular positioning rod is connected with an electrode perpendicular rotating body. The lower end of the electrode perpendicular rotating body is connected with an electrode multi-directional positioning connecting table. The lower end of the electrode multi-directional positioning connecting table is connected with an electrode swinging rotating body. The lower end of the electrode swinging rotating body is connected with an electrode horizontal rotating body. The lower end of the electrode horizontal rotating body is connected with an electrode. Multi-point mapping of animal heart electrophysiological parameters can be achieved, and the position of each detection point can be accurately determined with no large medical device.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to a positioning device, in particular to an in vivo cardiac electrophysiological stereotaxic positioning device. Background technique [0002] At present, in the in vivo study of arrhythmia in small animals, there are limited methods for cardiac electrophysiological mapping, and there is a lack of an accurate, non-invasive, simple, multi-site ECG mapping method on the heart surface. However, in the existing methods, vascular intervention is often used to send tiny electrode catheters (usually 2F) through the venous system of small animals to the right atrium and right ventricle for mapping. This method has the following disadvantages: first, the heart mapping site is limited, and only the right atrium and ventricle can be mapped, so that the measurement data is limited, and the mobility of the catheter is not strong, and some special parts of the heart cannot be reached. It ...

Problems solved by technology

This method has the following disadvantages: first, the heart mapping site is limited, and only the right atrium and ventricle can be mapped, so that the measurement data is limited, and the mobility of the catheter is not strong, and some special parts of the heart cannot be reached. It is beneficial to comprehensively evaluate the electrophysiological characteristics of the heart and predict the occurrence of arrhythmia; second, because small animals have small blood vessels and the overall blood volume of the whole body is small, the method of vascular intervention will inevitably affect the hemodynamics of small animals (such as blood loss during operation, local thrombosis or spontaneous bleeding due to excessive heparin), which increases the difficulty of experimental operations and reduces the survival rate of rat experiments, which is unfavorable to experimental research; The aid of imaging results of the equipment brings inconvenience to the experimental research and increases the cost of the experiment. Even the two-dimensional characteristics of imaging data cannot guarantee the accuracy of positioning and affect the accuracy of scientific experiments; fourth, use The supporting systems and consumables required for venous intervention are expensive, and currently there is no self-developed supporting system in China
