Description
Technical field
This utility model relates to a kind of light source adjustment device of diagnostic apparatus, especially for the adjusting device of the optical biopsy light source adjustment sheet 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 the defect of blemish in an otherwise perfect thing in this diagnostic apparatus light supply apparatus in control, exciter mercury lamp light source cannot regulate its energy size accurately, early stage, energy caused too by force image to whiten, and later stage energy is too weak causes fluorescence reaction weak, greatly affects the accuracy of instrument diagnoses.
Utility model content
In order to overcome the deficiencies in the prior art, this utility model provides a kind of adjusting device of optical biopsy light source adjustment sheet of optical biopsy energy of light source output intensity.
Have employed following technical scheme.
A kind of adjusting device of optical biopsy light source adjustment sheet, it comprises light source adjustment sheet and adjusting rod, light source adjustment sheet is arranged on the inner side of the focus lamp in lamp box header board, light source adjustment hole in light source adjustment sheet is corresponding with the position of focus lamp, light source adjustment sheet is connected with adjusting rod, and adjusting rod is connected with lamp box header board.
Light source adjustment sheet is a fan-shaped flake, and the fan edge position of fan-shaped flake is provided with light source adjustment hole, and light source adjustment hole is in involute slotted hole on fan-shaped circular arc direction, and the fan heart position of fan-shaped flake is provided with swing connecting hole and is connected with adjusting rod.

Fig. 2 is the structural representation of this utility model light source adjustment sheet;
Fig. 3 is that this utility model uses structural representation.
Reference numeral: mercury lamp 1, lamp box base plate 2, focus lamp 3, light filter 4, reflector 5, light source adjustment sheet 6, hold-down screw 7, positioning seat 8, lamp box header board 9, adjusting rod 10, positioning sleeve 11.
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 Fig. 1-3, the adjusting device of optical biopsy light source adjustment sheet comprises light source adjustment sheet 6 and adjusting rod 10, light source adjustment sheet 6 is arranged on inside the focus lamp 3 in lamp box header board 9, light source adjustment hole in light source adjustment sheet 6 is corresponding with the position of focus lamp 3, light source adjustment sheet 6 is connected with adjusting rod 10, and adjusting rod 10 is connected with lamp box header board 9.
Light source adjustment sheet 6 is a fan-shaped flake, and the fan edge position of fan-shaped flake is provided with light source adjustment hole, and light source adjustment hole is in involute slotted hole on fan-shaped circular arc direction, and the fan heart position of fan-shaped flake is provided with swing connecting hole and is connected with adjusting rod 10.
Lamp box header board 9 is provided with installing hole and is connected with positioning seat 8, the inner side of positioning seat 8 is fixedly connected with lamp box header board 9 by nut, the swing connecting hole of described light source adjustment sheet 6 is connected with one end end face of adjusting rod 10, the shaft of adjusting rod 10 and the adjustment guide hole of positioning seat 8 are rotationally connected, the outside of positioning seat 8 is provided with positioning sleeve 11, is provided with screw and is connected with the shaft of adjusting rod 10 in positioning sleeve 11.Adjusting rod 10 and positioning seat 8 be axial limiting under the effect of nut and screw, radial rotary.
The light that reflector 5 pairs of mercury lamps 1 send is on focus lamp 3.Allow light source adjustment sheet 6 swing by turn adjusting rod 10, the light source focused on is regulated.When the large orifice center of light source adjustment sheet 6 involute slotted hole is screwed into focus lamp 3 center, focused light source energy is the strongest.Otherwise when light source adjustment sheet 6 microstome center is screwed into focus lamp 3 center, focused light source energy is the most weak.
