Problems solved by technology

Scientific research shows that different tissues have different impedance spectrum characteristics, so the tissue type can be accurately identified by measuring the biological impedance spectrum characteristics of the target. different, and may exist in any part of the measured tissue, so that the measurement results cannot effectively and comprehensively reflect the characteristics of the tissue. If the impedance characteristics of the diseased tissue are to be accurately measured, the coverage of the impedance detection electrode is required to be small enough. However, when the impedance detection After the electrode coverage is small enough, it is necessary to repeat the detection of the measured tissue multiple times, and it is easy to cause missed detection, resulting in low detection efficiency, thereby reducing the effectiveness of the measurement

technical field [0001] The invention belongs to the field of bio-impedance measurement, in particular to a rapid measurement device and method based on bio-impedance technology. Background technique [0002] At present, in the process of clinical tissue biopsy in hospitals, frozen biopsy or paraffin biopsy is usually used. The test results of the two have great requirements on the individual identification ability of the examiners, so they are very subjective. Scientific research shows that different tissues have different impedance spectrum characteristics, so the tissue type can be accurately identified by measuring the biological impedance spectrum characteristics of the target. different, and may exist in any part of the measured tissue, so that the measurement results cannot effectively and comprehensively reflect the characteristics of the tissue. If the impedance characteristics of the diseased tissue are to be accurately measured, the coverage of the impedance detect...
