Description
Technical field
This utility model belongs to photoelectricity Medical Instruments technical field, is specifically related to a kind of laser probe.
Background technology
The transmission probe is the parts that transillumination light source is provided for breast examination, early stage mammary diagnosis instrument all is to adopt metal chlorination lamp or adopt ordinary incandescent lamp etc. to do after the special handling as light source, this class light source probe mixes a lot of visible lights, the problem that has the photosensitivity difference, the near infrared light that need to obtain also needs to be provided with some complicated structures, cause probe size bigger, inconvenient operation, and radiating effect is also bad.For overcoming these defectives, in recent years, research worker has been designed the LASER Light Source probe, can directly send simple near infrared light, simplifies the structure.What but the laser probe that has adopted is fiber optic conduction, and will carry out complicated variable cross-section to optical fiber and handle, and cost is than higher.Have technology to consider that the single-point light source irradiation is limited in scope again, can not satisfy the requirement of the range of exposures of different sizes, design is arranged the light source probe of the variable bright dipping bore that forms with a plurality of sub-light sources, luminously comes the conversion range of exposures by what control each sub-light source.But the light-emitting window area of this light source is big, light leak appears easily, light-emitting component directly is arranged in light-emitting window in addition, too near from the human body check point, cause scald after the heating easily, come the conversion lighting area by the switch of controlling each sub-light source exactly in addition, need to arrange abundant sub-light source, and not all sub-light source can both be utilized fully, so very flexible, and cost is also than higher.
Summary of the invention
The purpose of this utility model is the deficiency at the prior art existence, a kind of mammary diagnosis instrument transmission probe is provided, as luminous organ, do not need to use fiber optic conduction with laser instrument or infrared LED, simple in structure, illumination effect is good, light leak not, and can realize that multiple spot is luminous, adapt to the irradiated area needs of different sizes, distance is adjustable between the luminous point, uses flexibly.
The technical solution of the utility model is as follows:
A kind of mammary diagnosis instrument transmission probe, mainly by probing shell, be contained in control button on the housing, be contained in the intravital control circuit board of shell and laser is first-class forms, described laser head includes laser instrument or infrared LED, light pipe and leaded light pipe box, wherein the emission wavelength of laser instrument is 808nm, is the TO-3 encapsulation.Because laser emission angle is anisotropy, be unfavorable for observing, consider that simultaneously light source can not be too near to light-emitting window, in order to avoid heating is scalded, therefore laser instrument or infrared LED are fastened on the light pipe rear end, the light pipe inner chamber is circle surface-brightening and that certain taper is arranged, makes to obtain homogenize through wherein laser and handle and emit, make the zone of its irradiation wider, brightness is more even.The light pipe front end stretches out housing, and the leaded light pipe box that flexible material is made is installed, and makes the hard part of light pipe directly not contact skin of breast on the one hand, play cushioning effect, the comfort of strengthen using, the leaded light pipe box also plays airtight to light on the other hand, avoids the effect of light leak.
The tapering of light pipe inner chamber is determined by light pipe light inlet aperture, light pipe bright dipping aperture and light pipe length.The minima greater than the laser instrument optical window is got in light pipe light inlet aperture, and the bright dipping aperture determines that according to the needs of breast examination light pipe length should guarantee the angle of departure of tapering less than laser.
Further, in order to reach the upgrading of product, such as the diameter that increases light-emitting window (as being 30mm) or on original basis, shorten the length of light pipe by 10mm, making the instrument miniaturization purpose, also can be that the back-end location of light pipe is equipped with beam expanding lens at the light-emitting window place of laser instrument or infrared LED.In addition, in order to protect the light pipe internal structure, the light pipe front end is equipped with dustproof mirror.
In addition, control circuit board is the key control circuit plate, only controls the switching signal of button, more complicated other control circuit is not located on this circuit board, but it is fused in the outside mammary diagnosis instrument control circuit, like this, can simplify the structure of probe, alleviate probe weight.Laser head by lead with patch components and parts and be connected with the key control circuit plate, the key control circuit plate connects the control circuit of mammary diagnosis instrument by cable.
Above-mentioned is the probe of single light source, go among a small circle or the inspection of specific part used.This probe also can be the multiple light courcess structure, uses when being applicable to the bigger inspection of irradiated area.The multiple light courcess structure is to be arranged in juxtaposition above-mentioned laser head a plurality of in housing, they are fixed in the housing, form a plurality of light head, perhaps the some of them laser head are connected on the position adjusting mechanism, make its phase mutual edge distance adjustable, with flexible needs at various irradiated areas.
Described position adjusting mechanism can adopt a lot of existing techniques in realizing, but in order to make it simple in structure as far as possible, can adopt screw rod and regulate nut, screw rod is horizontally through the Connection Block of laser head, with its threaded engagement, the straight line that the rotation of screw rod is become laser head moves, and reaches the purpose of regulating distance between the light source.
The layout of a plurality of laser heads is the center with a fixed laser head preferably, and all the other are several to be connected with position adjusting mechanism, is distributed in around it.
Advantage of the present utility model is obviously: the one, and laser head is reasonable in design, and near infrared light efficiently can be provided, and is convenient to the photographic head blur-free imaging of instrument; The 2nd, simple in structure, volume is small and exquisite, and is in light weight, is convenient to operation; The 3rd, can form multiple light courcess, and scalable, be suitable for the range of exposures needs of all size flexibly.
