Optical fiber finger for detecting flexibility of prostate and detection method

Abstract

The invention relates to an optical fiber finger for detecting flexibility of a prostate and a detection method. The optical fiber finger comprises a laser light source, a sine excitation wave, a medical plastic membrane for being in contact with the prostate, a mono-mode sensing optical fiber for sensing vibration of the membrane, a 45-degree end face angle sensing mono-mode optical fiber processed by a polishing process, an optical fiber connector for connecting the mono-mode sensing optical fiber and an optical fiber detector, and an optical fiber detector for detecting toughness information of tissues. Aiming at the technical requirements on direct detection of the prostate, the invention designs the low-cost optical fiber finger capable of penetrating into a human body so as to carry out diagnosis on prostatic lesions; the size of each sensor is smaller than 5mm; paint brought to a patient by the prostatic lesions is greatly reduced. Meanwhile, small lesion tissues difficult to find can be detected, so that probability of finding abnormal tissues in the early stage is improved.

Description

technical field [0001] The invention relates to an optical fiber finger and a detection method for detecting the flexibility of the prostate. Using the principle of optical fiber interference, the instrument reflects information about the surface morphology and toughness of the prostate by detecting the relative position change of the plastic film and the optical fiber. It can provide diagnostic basis for related prostate lesions and prostatic cancer, and effectively prevent the further development of prostate lesions. Background technique [0002] In modern society people pay more and more attention to health care. The pace of development of the personal healthcare industry is increasing year by year. As a high incidence of male diseases in the world. [0003] At present, there are mainly three detection methods in the world: prostate biopsy technology, prostate specific antigen (PSA) detection and digital rectal examination. Prostate biopsy generally requires anal or pe...

Problems solved by technology

[0005] The above-mentioned articles and patents are all based on the electronic sensing system. The detection part is bulky and cannot accurately locate the lesion. At the same time, the human body is exposed to electromagnetic radiation noise, so it is not suitable for actual contact detection of the prostate, and its applicability is poor.
