Description
Technical field
This utility model relates to a kind of light supply apparatus of diagnostic apparatus, especially for a kind of optical biopsy light supply apparatus of mucosal pattern early diagnosis of cancer.
Background technology
At present, in Chinese patent CN85100424, disclose optical biopsy precancerous lesion image diagnostic instrument, adopt black light as exciting light, be transferred to surface of living body tissue through silicon fiber, this biological tissue is excited and produces its primary fluorescence.For malignant tumor, the primary fluorescence that its aberration can use discernable by eye can be inspired.This diagnostic method is easy and simple to handle, rapid, not damaged, and cost is low, to detect accuracy rate high, is particularly useful for the early stage property cancer screening such as oral cavity, cervix uteri, vagina, anal canal, rectum.
Chinese patent ZL00216974.6 discloses a kind of diagnostic apparatus light supply apparatus, its basic comprising comprises following concrete component: cabinet, vertical setting is used to provide the exciter of exciting light, for providing the illuminating lamp of illumination light, reflector, light filter, the condenser lens of reflection black light, its position relationship is: the light sent by exciter injects the optical fiber head being positioned at its focal position, focal plane after the light line focus lens focus that reflector reflecting focal, light filter filter, and is transmitted through the fiber to tissue to be checked.The light supply apparatus of natural fluorscence diagnosis instrument used for diagnosising malignant tumour is contributed.But still there is blemish in an otherwise perfect thing in this diagnostic apparatus light supply apparatus:
1. due to optical imagery, the light that exciter sends must through reflector reflect focalization, then also must light filter filter after focus on optic fibre end with condenser lens and conduct again, the energy of the output reduced greatly;
2. whole system needs each optics precision-fit, and installation and debugging are not easily accurate, also easily causes the light energy of the output reduced by extraneous carrying vibration influence;
3. the limitation of exciter mercury lamp light source itself, light source is pure not, color chips filtering after filtration.Mercury lamp is short for service life, and thermo-field thoery when using.
Utility model content
In order to overcome the deficiencies in the prior art, this utility model provides a kind of optical biopsy light supply apparatus.
Adopt following technical scheme.
A kind of optical biopsy light supply apparatus, it comprises lamp cylinder and cable, wherein, is provided with light source control plate, one or one group of LED source, one-level lens and secondary lens in lamp cylinder successively; Cable is connected with one or one group of LED source by light source control plate, and the shift knob on described light source control plate, energy are strengthened being exposed in the cylindrical shell aperture of lamp cylinder outside button and energy dropoff button.
One or one group of LED source, coaxial and lamp cylinder axial distance is adjustable relatively between one-level lens and secondary lens.
The camera lens of one-level lens is flexibly connected with the front end of lamp cylinder, and the camera lens of secondary lens is connected with the lens movable of one-level lens.
The beneficial effects of the utility model have:
1. private-use class light emitting diode, the pure light source of 300nm ~ 400nm wave band exports, and saves energy consumption, greatly reduces again the heat condition of device simultaneously.This LED power is low, and the life-span is far away higher than the mercury lamp life-span.
2. can realize Non-follow control, accurately adjust ultraviolet light source and export energy, improve the degree of purity of light source.
3. two pieces of lens scalable longitudinal separations, can export the circular light spot of different size and light energy.
Accompanying drawing explanation
Fig. 1 is structure principle chart of the present utility model.
Fig. 2 is this utility model light source wiring board button schematic diagram.
Reference numeral: secondary lens 1,2, one, one-level lens or one group of LED source 3, light source control plate 4, shift knob 41, energy strengthens button 42, energy dropoff button 43, lamp cylinder 5, cable 6.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model will be further described, but scope of the present utility model is not limited to following embodiment.
Embodiment 1: as shown in Figure 1, a kind of optical biopsy light supply apparatus, it comprises lamp cylinder 5 and cable 6.Light source control plate 4, or one group of LED source 3, one-level lens 2 and secondary lens 1 successively in lamp cylinder 5.
The camera lens of one-level lens 2 is flexibly connected with the front end screw thread of lamp cylinder 5, and the camera lens of secondary lens 1 is flexibly connected with the camera lens screw thread of one-level lens 2.
One or one group of LED source 3, coaxial between one-level lens 2 and secondary lens 1, relative lamp cylinder 5 axially, can regulating of the spacing of or a group LED source 3, one-level lens 2 and secondary lens 1.As realized by rotating the modes such as threaded adjusting.
As shown in Figure 2, light source control plate 4 there are three buttons, are respectively shift knob 41, energy strengthens button 42 and energy dropoff button 43, control light source switch respectively, energy of light source is strong and weak.
One or one group of LED source 3 can send the ultraviolet of high-purity 300nm ~ 400nm wave band, and export the requirement that energy can meet optical biopsy.
One-level lens 2 and secondary lens 1 are made up of the uv-transmitting material of height, improve the degree of purity of light source.Cable 6 is connected with electric power for the data of lamp cylinder 5.
Light source control plate 4 is by manual adjustments light source switch, and energy is strong and weak.In fig. 2, light source is clicked
The shift knob 41, one of panel 4 or one group of LED source 3 receive cable 6 and transmit power supply and start to light.The irradiation energy of energy reinforcement 42, one, the button or one group of LED source 3 that click light source control plate 4 will strengthen.The irradiation energy of 43, one, the energy dropoff button or one group of LED source 3 that click light source control plate 4 will reduce.
In FIG, one or one group of LED source 3 send highly purified light source through one-level lens focus on secondary lens, then are gone out the circular light spot of a branch of energy even by secondary lens reflection, project tissue to be checked for optical biopsy.By axial adjustment secondary lens 1 and one-level lens 2 front and back position, realize regulating and project the size organizing light source irradiation area to be checked.
