Multi-photon fluoroscopy attachment module for surgical microscope

Abstract

The present invention relates to an attachment module (100) for a surgical microscope (10), the attachment module (100) being insertable into a main optical path between an objective (11) of the surgical microscope and an object (O) being observed, and including: a multi-photon fluoroscope (110) including a light source (111) for emitting excitation light, a scanning device (112) for directing the excitation light onto the object (O), and a detector (113) for detecting fluorescent light emitted from the object (O); and input coupling optics (120) for reflecting the excitation light from the scanning device onto the object (O).

Description

technical field [0001] The invention relates to an auxiliary module for a surgical microscope, an examination device comprising such an auxiliary module and a microscope system comprising such an examination device. Background technique [0002] In microscope-assisted surgery, light microscopic imaging can be supported by other methods. For example, it is known from the article "Combining Optical Coherence Tomography (OCT) with an Operating Microscope, E. Lankenau et al., Advances in Medical Engineering, Springer Verlag, Vol. 114, pp. 343-348" that an operating microscope can be equipped with an OCT ( Optical coherence tomography) unit so that images from deeper layers can be utilized in addition to light microscopic images of the eye, especially in ophthalmology. The magnification of the surgical microscope and the magnification of the OCT unit are of the same order of magnitude. [0003] In neurosurgery, as described, for example, in DE 10 2005 005 984 A1, fluorescence m...
