Because visible light is used as the light source, the utility model not only has low power, but also has convenient operation and use and the utility model is safe.
Description
Technical field
This utility model relate to a kind of improved be applied to the mammary diagnosis instrument light source.
Background technology
Mammary diagnosis instrument is a kind of common Medical Instruments.Existing mammary diagnosis instrument adopts strong illumination mostly, and the light source caloric value of this type of mammary diagnosis instrument is big, and uses inconvenient.Thus, the scheme that improves at the light source of mammary diagnosis instrument has appearred in industry, for example No. the 01244641st, No. the 01125666th, Chinese patent application, No. the 01234252nd, Chinese patent application and Chinese patent application have all proposed improvement project to the light source of mammary diagnosis instrument, and have all adopted the LASER Light Source of higher-wattage.For example, laser light-source device in a kind of near-infrared mammary diagnosis instrument described in No. the 01125666th, the Chinese patent application, it has adopted the LASER Light Source of 810 nanometers, yet, because the wavelength of visible light scope is 400 nanometer to 760 nanometers, therefore the light source of this wavelength is invisible to human eye, and then can not with the naked eye judge the on off state of light source easily, be not easy to also judge whether light source is in normal user mode, in practical operation, bring a lot of inconvenience, even may in use cause danger.Simultaneously, adopt the LASER Light Source of 810 nanometers, its power generally reaches the hundreds of milliwatt also than higher.
On the other hand, general laser instrument polarization light output, but for mammary gland tissue adopts the circularly polarized light can be so that imaging depth is bigger as incident illumination, promptly can minimizing and laser power and better image quality is arranged.
In sum, design a kind of easy to use, safe and power is less, the mammary diagnosis instrument light source of good imaging quality is real in necessary.
Summary of the invention
The purpose of this utility model is that design is easy to use, safe and power is less, the mammary diagnosis instrument light source of good imaging quality.
For achieving the above object, the mammary diagnosis instrument light source that this utility model provides comprises that it comprises the chamber of being made up of jointly back segment, stage casing and leading portion, wherein be fixed with laser diode in the stage casing, be fixed with potentiometer, collimating mirror, circular polarization mirror and lamp guide in the leading portion, one lead enters and electrically connects with laser diode, potentiometer respectively from back segment, wherein the laser diode emission wavelength is between 400 nanometer to 760 nanometers, and laser diode power is lower than 80 milliwatts.
By above scheme as seen, with respect to known mammary diagnosis instrument light source, this utility model adopts visible light as light source, naked eyes can be judged its switch and user mode, can not shine human body for a long time owing to maloperation, and because its power is lower, also can produce and burn even shine human body for a long time, therefore manipulate very convenient, safety.Adopt the circular polarization mirror simultaneously, improved image quality.
Description of drawings
Fig. 1 is the sketch map of this utility model embodiment.
The utility model is described in further detail below in conjunction with Fig. 1 and preferred embodiment.
Embodiment
Please refer to shown in Figure 1, the preferred embodiment of this utility model mammary diagnosis instrument light source 1 comprises the chamber of being made up of jointly back segment 1, stage casing 2, leading portion 3, wherein be fixed with laser diode 21 in the stage casing 2, being fixed with potentiometer 30, collimating mirror 32, circular polarization mirror 33 and lamp guide 34, one leads 4 in the leading portion 3 enters and electrically connects with laser diode 21, potentiometer 30 respectively from back segment 1.Wherein laser diode 21 emission wavelengths are between 400 nanometer to 760 nanometers, and the power of laser diode 21 is lower than 80 milliwatts.
One end of back segment 1 has an opening 10, the other end is connected with stage casing 2 buckles, the inboard in stage casing 2 is provided with two symmetric boss 20, the bottom 210 of laser diode 21 places on the boss 20, and bottom 210 is fixed on the boss 20 by screw 22, and the part of laser diode 21 is placed in the leading portion 3 and links to each other with a end of pipe 31 in the leading portion 3; A collimating mirror 32 is set in the pipe 31, and a side of the other end of pipe 31 and circular polarization mirror 33 is protected bias tyre lamp guide 34 near, the opposite side of circular polarization mirror 33 near one, and the part of lamp guide 34 is clamped in the leading portion 3, and the other end then places leading portion 3 outsides.Leading portion 3 also is connected with stage casing 2 by the buckle mode, and fixes the potentiometer 30 of a control electric current on the sidewall of leading portion 3.Lead 4 enters into back segment 1 from opening 10, and passes back segment 1 and electrically connect with laser diode 21, potentiometer 30 respectively.
During assembling, now laser diode 21 is fixed on the boss 20, and potentiometer 30 and lead 4 are installed simultaneously, then back segment 1, stage casing 2, leading portion 3 are fastened, and make pipe 31 near laser diode 21.
As a preferred embodiment of the present utility model, the power of laser diode 21 is 40 milliwatts, and its optical source wavelength that sends is 640 nanometers.Light passes and enters lamp guide 34 behind collimating mirror 32 and the circular polarization mirror 33 and penetrate from the other end of lamp guide 34, and the inside of lamp guide 34 can be optical fiber or other material.
During assembling, earlier pipe 31, laser diode 21, collimating mirror 32 are assembled into an integral body, then with this overall fixed on boss 20, potentiometer 30, lead 4, circular polarization mirror 33 and lamp guide 34 are installed then, at last back segment 1, stage casing 2, leading portion 3 fastened.
Obviously, in the above-mentioned preferred embodiment since optical source wavelength be 640 nanometers, the scope that belongs to visible light, in the use, the operator can with the naked eye judge the on off state of light source, can judge easier also whether light source is in normal user mode, the human body of can not burning because of maloperation, on the other hand, the power of laser diode 21 reduces greatly than prior art, even long-time irradiation can not damage human body yet, therefore adopt the mammary diagnosis instrument of this LASER Light Source very easy to use, safety.Simultaneously, adopt the circular polarization mirror, improved image quality.
Be appreciated that technical conceive of the present utility model is not limited in the foregoing description, can also obtain many different concrete schemes according to design of the present utility model, for example, laser diode 21 can wait other modes to be fixed on the boss 20 by welding; In addition, can not adopt pipe 31, but directly collimating mirror 32 and circular polarization mirror 33 are fixed on the inwall of leading portion 3, at this moment, laser diode 21 need be nearer from collimating mirror 32.Suchlike equivalent transformation all should be included within the described scope of claim.
