Miniature and high brightness luminescence source for medical inflexible endoscopeTechnical field
The present invention relates to a kind of medical apparatus and instruments, relate to particularly that a kind of volume is little, in light weight, power consumption is low, can supply power with double circuit, non-maintaining, Miniature and high brightness luminescence source for medical inflexible endoscope that bulb service life is long.
Background technology
At present, be used in the illuminating endoscope of medical field cold light source 4 types of adopting both at home and abroad: (1) based on light more. Halogen light cold light source, its power 100W-250W; (2). xenon lamp cold light source, its power 300W-350W; (3). Metal halogen lamp cold light source, its power 250W; (4) short-arc lamp cold light source, its power 22W.
More than four types light source in application, have following weak point:
1. all be under alternating current 220V voltage, to work.Particularly lighting of xenon lamp and Metal halogen lamp and short-arc lamp need be lighted by starter under kilovoltage.And Halogen light also has color temperature difference and has been not suitable as medical field endoscope cold light source and uses.
2. the heat that sends after lighting of bulb is high.And its heat is directly proportional with brightness, so the cooling in the cabinet becomes a big problem of the required solution of Medical Cold Light Source.
3. bulb service life is short.Wherein, Halogen light 50-60 hour; Xenon lamp 100 hours; Metal halogen lamp 250 hours; The short-arc lamp time is slightly long.Its price all than higher as: Metal halogen lamp, xenon lamp, short-arc lamp price are all in RMB more than several thousand yuan.
4. in use all need the leaded light cable of a diameter 10mm, long 1.8-2.0 rice to connect the use of rigid endoscope.
Summary of the invention
Technical problem to be solved by this invention is: provide that a kind of volume is little, heat is low, can supply power with double circuit, power consumption is low, non-maintaining, Miniature and high brightness luminescence source for medical inflexible endoscope that bulb service life is long.
The technical solution adopted in the present invention is: a kind of Miniature and high brightness luminescence source for medical inflexible endoscope includes: bulb, hand-held housing, bonder, bulb fixed mount, heat-conducting layer, radiator, electric cabinet, insulation board, constant-current driving plate.Wherein, hand-held housing, radiator, electric cabinet are for connecting successively; In the hand-held housing is hollow structure, the top of its hollow structure is formed with rigid endoscope connector, and the lower part is provided with bonder, and the lower end of bonder is provided with the bulb fixed mount, bulb is fixedly installed on the bulb fixed mount, and the downside of bulb fixed mount is provided with heat-conducting layer; Upper port in electric cabinet and radiator junction are provided with insulation board, and the constant-current driving plate is arranged on the lower end of insulation board, and the bottom nozzle of electric cabinet is provided with bottom, are formed with the lead intercommunicating pore on its bottom.
Described heat-conducting layer adopts heat-conducting silicone grease to make, and is formed with the lead intercommunicating pore on it.
Described insulation board adopts poly-tetrafluoro plate to make, and is formed with the lead intercommunicating pore on it.
Bottom and bonder joint at the intravital endoscope of described handheld housing connector are provided with seal glass.
Described bonder is fixed on above the bulb fixed mount by the bonder holder.
Described bonder holder is the structure that is connected with the bulb fixed mount.
The sidewall of described electric cabinet is provided with the brightness regulation knob that is connected with the constant-current driving plate.
Described bulb is that direct current 12V and lithium battery supply power with double circuit.
Be hermetically sealed waterproof connecting structure between described hand-held housing, radiator, electric cabinet and the bottom.
Miniature and high brightness luminescence source for medical inflexible endoscope of the present invention is direct current 12V and the power supply of lithium battery double circuit.In direct current 12V work, automatically switch by lithium battery power supply when cutting off the power supply suddenly.When direct current 12V works, will after being full of, cut off the power supply automatically, and discharge is protected, but continuous operation be more than 4 hours automatically to the lithium battery system charging.And this light source volume is little, and in light weight, cost is low, and power consumption is low, long service life.Do not contain deleterious ultraviolet light or infrared ray hotness in the light beam that bulb sends, belong to cool light.Its light source color temperature is 6000K, is daylight type, and brightness reaches as high as 350,000/LX, and adjustable brightness.This light source is full waterproof construction, can whole soaking disinfection.Bulb life is more than 100,000 hours.Free of replacement, non-maintaining.

The specific embodiment
Describe the specific embodiment of Miniature and high brightness luminescence source for medical inflexible endoscope of the present invention in detail below in conjunction with accompanying drawing.
Miniature and high brightness luminescence source for medical inflexible endoscope of the present invention, include:bulb 6, hand-heldhousing 3, bonder 4, bulb fixedmount 7, heat-conductinglayer 8,radiator 9,electric cabinet 10,insulation board 12, constant-current driving plate 13, wherein, hand-heldhousing 3,radiator 9,electric cabinet 10 are for connecting successively; In the hand-heldhousing 3 is hollow structure, the top of its hollow structure is formed with rigid endoscope connector 1, the lower part is provided with bonder 4, the lower end of bonder 4 is provided with bulb fixedmount 7, bonder 4 is fixedly installed on above the bulb fixedmount 7 by bonder holder 5, and bonder holder 5 and the structure of bulb fixedmount 7 for being connected.Bulb 6 is fixedly installed on the bulb fixedmount 7, and is positioned at the lower end of bonder 4.The downside of bulb fixedmount 7 is provided with heat-conductinglayer 8, and heat-conductinglayer 8 adopts heat-conducting silicone grease to make, and is formed with the lead intercommunicating pore on it.Upper port inelectric cabinet 10 andradiator 9 junctions are provided withinsulation board 12, andinsulation board 12 adopts poly-tetrafluoro plate to make, and also is formed with the lead intercommunicating pore on it.Constant-current driving plate 13 is arranged on the lower end ofinsulation board 12, and the bottom nozzle ofelectric cabinet 10 is provided withbottom 14, is formed with the lead intercommunicatingpore 16 that can passpower line 15 on itsbottom 14.
