Abstract
The present invention relates to medical equipment technology, and the endoscope has one built-in cold light source set inside its hard tube. The present invention is simply one hard tubular mirror comprising LED, electric wires, outer tube, inner tube, photoconducting fiber and interface. It features that several LEDs are arranged in the interface between the inner tube and the outer tube and have one end connected parallelly and the other end connected to the power supply. Its use can reduce the labour intensity of medicine operator and it has relatively reliability owing to its less elements and devices.
Description
The present invention relates to medical hard-tube endoscope that cold light source is built in endoscope, belong to technical field of medical instruments.
For patient diagnoses, needs sometimes to use medical hard-tube endoscope when treating, enter in the endoscopic observation body of human body in the hospital, need brightness of illumination just to need light source.And ordinary light source is multispectral line composition, have wherein very that major part is an infrared light, the heat of infrared light especially can produce enough energy to mucosa to human body burns it, and therefore requiring light source must be cold light source, be about to a large amount of infrared light compositions and filter, make it to become cold light source comparatively speaking.The cold light source that uses is that halogen tungsten lamp, xenon lamp etc. are made light source mostly at present, and infrared light is filtered out, and focuses on the interface that optical cable enters the hard tube mirror again, as shown in Figure 1.Medical hard-tube endoscope is made up of hard tube mirror 1, light source 2 at present, and hard tube mirror 1 is made up of outer tube 4, interior pipe 5, optical fibers 6, interface 7, and optical cable 3 is used for connecting hard tube mirror 1 and light source 2.Though since halogen tungsten lamp also xenon lamp all need go up hectowatt to the power supply of several hectowatts, and by a series of components and parts to light source filter, processing such as focusing, so this cold light source volume is bigger, the life-span of electric light source and reliability all are subjected to the restriction of component quality, must there be simultaneously a heavier optical cable to connect, move inconvenience, a kind of heavy traction sense is arranged during use.
The object of the present invention is to provide a kind of cold light source to be built in the interior medical endoscope of hard tube mirror, thereby carry, use very light.
Purpose of the present invention realizes in the following manner: use the light emitting diode alternative source of light, and place it in the interface section of hard tube mirror, specific practice is: several light emitting diodes are centered between the inner and outer pipes of the interface section that is arranged in the hard tube mirror, be connected in parallel between the light emitting diode, its other end is connected with power supply.
From the present invention as can be seen of above scheme, carry and use very convenient.Because cold light source is placed on the interface section of hard tube mirror, save heavy power supply and optical cable, alleviated medical workers certainly.Because the components and parts that cold light source of the present invention uses are few, improved reliability of products certainly.
Reach accompanying drawing in conjunction with the embodiments and specify structure of the present invention.
Fig. 1 is present external cold light source medical endoscope sketch map
Fig. 2 is the sketch map of the embodiment of the invention
Referring to accompanying drawing 2.Medical hard-tube of the present invention endoscope is exactly a hard tube mirror 1, and hard tube mirror 1 is made up of light emitting diode 2, electric wire 3, outer tube 4, interior pipe 5, optical fibers 6, interface 7.Pipe 5 outsides in outer tube 4 is enclosed within, row has optical fibers 6 between the two, and interface section 7 rows of interior pipe 5 have the light emitting diode 2 of mutual parallel connection, and the other end of light emitting diode 2 is connected with power supply by electric wire 3.Power supply is external unidirectional current among this embodiment, also can be internal battery.
In use, when light emitting diode 2 passed through electric wire 3 with power connection, light emitting diode 2 sent cold light.Because the overwhelming majority have only few near infrared light, thereby the light that light emitting diode 2 sends is cold light for the visible light composition in the spectrum of the light that light emitting diode 2 sends.This cold light can use for observing by coming the interior prosopyle end that 5 outer optical fiberss 6 reach hard tube mirror 1 of managing.
Claims (1)
1. an endoscope with built-in cold light source comprises that outer tube (4), interior pipe (5), optical fibers (6), interface (7) is characterized in that outer tube (4) is enclosed within interior pipe (5) outside, row has optical fibers (6) between two pipes, and row is gone up in the interface section (7) of interior pipe (5) has several light emitting diodes (2) in parallel mutually, the other end of light emitting diode (2) to be connected with electric wire (3).
