Abstract
The utility model relates to a screen image enhancement device for medical use, which uses a positioning button to control two color filters so as to eliminate the interference of the primary fluorescence. A variable optical stop before an image tube adjusts the intensity of the incident light so as to protect an image enhancement tube. An additional movable interface can be connected to various endoscopes and superficial mirrors so as to enlarge the medical application range of the whole machine. The spectral bandwidths of the two color filters are 625-635 mm and 685-695 mm, and the optimum wave lengths of the two color filters are 630-690 mm. The device has stable performance and high fluorescence positioning accuracy and reduces the false positive rate by three times, and the device can be used for the fluorescence detection of a plurality of endoscopes. The utility model is a necessary device for the fluorescence detection of the tumours inside and outside the body cavity for the medical use.
Description
This utility model is the optical system instrument.
The subject matter that is used for the enhancing instrument existence of the inside and outside small lesion tumor fluoroscopic examination of body cavity before is: because the spectral line instrument of optical filter is 630nm, make false positive rate up to 19%, and high light damages image intensifier tube when avoiding imaging, the light-shading apparatus that the Ceng Youyong reflected light path is made, but producting process difficulty height, the operating technology complexity costs an arm and a leg and is difficult to popularize.And because the interface disunity has limited Instrumentation Operating Areas.This utility model is developed for addressing these problems.
Main points of the present utility model are alternately to be filtered by two optical filters of 625~635nm(8), 685~695nm(9) of navigation button (3) control, remove the interference of normal structure from source fluorescence.Image strengthens instrument object lens parts (7) iris (2) is housed, and regulates the input light intensity when the high light width of cloth shines, protection image intensifier tube (1); Additional Active Interface (4) but the joint (10,11) of connector intracavity sight glass and make shallow table mirror (12).The optimal wavelength of two optical filters is 630nm and 690nm.

The experiment proved that, the utility model fluorescence localization accuracy height, imaging clearly, false positive rate have reduced by 3 times; The stable performance of protection image intensifier tube, it is convenient to make simple operations, and price reduces, and because additional Active Interface has enlarged the scope of application, is the essential optical instrument of medical tumour fluoroscopic examination.
