Abstract

A medical high-flux serum Raman spectrum prostate cancer diagnostic instrument comprises a detection platform and a computer, the detection platform comprises a sample disc, an automatic silver sol mixing device is arranged above a sample mixing window, a first spectroscope and a second spectroscope are arranged above a detection window, the second spectroscope is arranged above the first spectroscope, and the computer is connected with the first spectroscope and the second spectroscope. A laser light source is arranged on the right of the first spectroscope, a focusing camera is arranged above the first spectroscope, a microscope objective is arranged between the second spectroscope and the detection window, a focal length controller is arranged on one side of the microscope objective, and a Raman spectrum acquisition system is arranged on the right of the second spectroscope. The uniquely-designed circular sample disc structure is controlled by the computer and the first driving device to rotate in sequence, and automatic sample adding and detection are completed. And the detection objective lens is kept fixed, so that the stability of the Raman detection system is ensured. The automatic focusing correction system ensures the quality and efficient acquisition of Raman spectrum data.

Description

technical field [0001] The invention relates to articles for human life, in particular to a medical instrument, in particular to a medical high-throughput serum Raman spectrum prostate cancer diagnostic instrument. Background technique [0002] With the development of my country's aging population and changes in lifestyle, the incidence of prostate cancer is increasing year by year in my country, ranking sixth among new male malignant tumors in my country. Since prostate cancer screening has not yet been popularized, most prostate cancer patients are already in the middle and advanced stages when they are diagnosed, and the overall prognosis is far worse than that in European and American countries. Currently, the most commonly used clinical screening tool is prostate-specific antigen (PSA). Since PSA is a tissue-specific rather than tumor-specific marker, its specificity and sensitivity to prostate cancer are low. Low sensitivity leads to underdiagnosis of prostate cancer,...
