Description
Technical field
It the utility model is related to lighting technical field, more particularly to a kind of portable illuminator.
Background technology
Optical imagery is an indispensable technology to clinical treatment.The main advantage of optical microphotograph imaging is its energy
Reach micron, the spatial resolution of sub-micrometer scale.Magnetic resonance imaging (MRI), computerized tomography (CT), ultrasonic imaging
With Positron emission tomography (PET) technology be in current clinical treatment commonly use image technology, they can Real Time Observation patients or
The metabolism of living animal or nervous function activity.But their spatial resolution is relatively low, it is difficult to reaches the resolution ratio of micron dimension.
Recently, there is fluorescence airmanship in the art based on fluorescein sodium, for guiding doctor to cut off glioblastoma brain
Tumour.Because malignant tumour is in infiltrative growth is diffused, unclear with surrounding normal brain tissue, the past relies on tumor color and quality
Rate only about 1/3, therefore patient's often rapid recurrence after surgery are cut entirely Deng micro-judgment.It is and right under the fluorescence guiding of fluorescein sodium
Glioblastoma carries out microscopic visual servo, can be realized in art tumour be presented certain particular color fluorescence and normal cerebral tissue not
It is luminous, so as to realize the accurate surgery excision of glioblastoma, while effectively protection tumour surrounding normal under surgical operation microscope
Brain tissue, patient tumors can be significantly improved and cut rate, extension life cycle and and improvement patients ' life quality entirely.Therefore, major optics
Manufacturer has produced the surgical operation microscope of fluorescence type one after another, the M530 OH6 types of OPMI PENTERO 900, Leica such as Zeiss
Surgical operation microscope, support to carry out fluorescein sodium imaging.
However, the optical image technology for being applied to clinical diagnosis and treatment at present still there is limitations.One is can
See that penetration capacity of the light in biological tissue be not strong, limited to optical imagery major applications face only in body surface or tissue surface；
The second is the resolution ratio that give full play to optical imagery also requires certain optical chromatography ability, to avoid afocal veiling glare
Interference.
Can solve the problems, such as both the above using two-photon fluorescence illumination.Two-photon fluorescence imaging technology generally uses femtosecond arteries and veins
Impulse light improves instantaneous luminous power to strengthen fluorescin nonlinear excitation efficiency.The characteristics of nonlinear excitation of two-photon effect
Also so that two-photon fluorescence imaging technology is provided with natural tomography effect and high spatial resolution, it is used near red
Scattering and absorption coefficient of the outer light source in biological tissue are small, and imaging depth can reach hundreds of microns to millimeter.
Two-photon fluorescence imaging art has huge clinical practice potentiality, but worldwide there is not yet really ripe
One of reliable clinical practice, its main difficulty are：Traditional femtosecond laser light source machine volume is big, weight is high, and after installation
It can not move, must be placed on anti-vibration platform.In addition, the characteristics of two-photon fluorescence illumination path volume is big, weight is high causes difficulty
To be applied on surgical operation microscope, and key problem to be solved in the utility model.
