Electrode fixing and locating device for breast impedance imaging

Abstract

Provided is an electrode fixing and locating device for breast impedance imaging. The electrode fixing and locating device comprises main rods 2, pull rods 4, a lifting plate 6, a bottom plate 7, and a linear guide rail module 8. The lifting plate 6 is provided with a main rod radial motion groove 9, the main rods 2 penetrate through the main rod radial motion groove 9, one end of each main rod 2 is hinged to the bottom plate 7 in a rotating mode, and the other ends of the main rods 2 are connected with electrodes 1. One end of each pull rod 4 is hinged to the main rods 2 and the other ends of the pull rods 4 are hinged to the lifting plate 6 in a rotating mode. The linear guide rail module 8 is connected with the lifting plate 6 and the bottom plate 7, and the lifting plate 6 is parallel with the bottom plate 7. A detected target is placed in the space formed by enclosure of the electrodes 1. The external force enables the lifting plate 6 and / or the bottom plate 7 to slide in the vertical direction under the guide of the linear guide rail module 8. The pull rods 4 are matched with the main rods 2 through rotation and push the main rods 2 to drive the electrodes 1 to be closed, and therefore the electrodes 1 make contact with the detected target according to an established mode, uniformity of contact between each detection electrode and the breast tissue can be guaranteed, model errors of remodeling imaging can be reduced, and the detection effect can be improved.

Description

Technical field [0001] The present invention involves a signal acquisition equipment in the breast resistance impedance imaging equipment, which specifically involves a device that involves a different electrode in the same plane circular meter at the same plane circle. Background technique [0002] Due to the obvious differences between the resistance characteristics of the lesion tissue and the normal biological tissue, the medical imaging technology that uses the principle of biological impedance, such as the Electrical Impedance Tomgeraphy (EIT), the Electrical Impedance SpectrosCopy (EIS), EIS,Can effectively detect and position the lesions of the organism.Medical imaging technology that uses the principle of biological impedance is placed on the surface of the biological body and injected low -frequency and low -power currents, and the voltage difference between the electrode detects the internal impedance distribution of the organism. Due to the different impedance charact...

Problems solved by technology

[0003] Since the electrical impedance mammography technology is to place multiple electrodes in a certain arrangement to ensure the quality of imaging, the placement of electrodes for different test targets must conform to a unified pattern, so if the electrodes are placed directly on the surface of the target by the operator, Difficult to ensure electrode arrangement consistent with pre-planned patterns, uniformity and consistency across different test targets, negatively impacts imaging quality, and requires significant time-consuming draining of electrodes before each test

[0004] Due to the differences between test target individuals, it often occurs that the skin of the test breast does not fully contact with some electrodes, or even gaps appear, resulting in some electrodes not in contact with the skin of the test breast, and some electrodes are not in good contact with the skin, resulting in a gap in the electrode array. Certain electrodes cannot provide corresponding real electrical signals, which will inevitably affect the imaging effect and diagnostic results of the electrical impedance mammography system
