A confocal microprobe with a bending alarm function, its supporting device and detection method

Abstract

The invention discloses a confocal miniature probe having a bending alarm function and a matching device and a detection method thereof. The confocal miniature probe comprises a mage-carrying fiber bundle connector plug, a protection fiber connector plug, a mixed fiber and a miniature objective lens. The far end of the mixed fiber is connected with the miniature objective lens; the near end of the mixed fiber is branched into an image-carrying fiber bundle branch and a protection fiber branch; optical power attenuation or reflection spectra migration of the mixed fiber is detected through the protection fiber branch so as to judge the bending degree of the fiber; the image-carrying fiber bundle branch is connected with one end of the mage-carrying fiber bundle connector plug; the protection fiber branch is connected with one end of the protection fiber connector plug; and the other end of the mage-carrying fiber bundle connector plug and the other end of the protection fiber connector plug are used for connecting with a socket on a confocal microendoscope main machine. The confocal miniature probe is exquisite in structure and low in cost, solves the problem that a conventional confocal microendoscope cannot detect over bending of the miniature probe, and reinforces protection of the core component, an image-carrying fiber bundle, in the miniature probe.

Description

technical field [0001] The invention belongs to the technical fields of medicine and biology, and more specifically relates to a confocal microprobe with a bending alarm function, its matching device and detection method. Background technique [0002] Confocal microendoscope is an endoscope that uses the principle of confocal imaging for microscopic imaging. It is mainly used in the fields of medicine and biology for imaging biological tissues. Currently, the most commonly used clinical method is probe-type confocal Microscope. The probe-type confocal microendoscope uses an imaging fiber bundle composed of tens of thousands of optical fibers for imaging. The host side of the endoscope uses a scanning galvanometer to scan the proximal end of the fiber bundle line by line, and injects the focused laser light into the fiber core of the image-transmitting fiber-optic bundle in sequence, and at the same time receives the fluorescence transmitted back through the image-transmitti...
