Abstract
The present invention discloses a therapeutic instrument through irradiation by laser in blood vessels. The present invention is characterized in that a visible light semiconductor laser generator is used as a laser source; laser is transmitted by an optical fiber coupler and optical fiber to an optical needle head; a casing tube of a medically left puncture needle head is connected, and blood is directly irradiated by laser. The present invention has the characteristics of small volume, light weight, portability for doctors who can carry about the present invention in pockets during home visits, high voltage power and freedom from the limitation of a power supply as a result of using dry cells as a power supply, different therapy requirement satisfaction due to convenient adjustment of the transmitting power of laser, no cross infection due to the use of the disposable optical needle head, etc. Practical tests indicate that the present invention has favorable therapeutic effects on cardio-cerebrovascular diseases.
Description
The present invention relates to a kind of optical fiber output semiconductor visual laser endovascular radiating instrument device.
In recent years, light haemodialysis method has obtained to use widely in medical science, and especially the low level laser intravascular brachytherapy has showed bright prospect.But what adopt at present is this gas laser intravascular brachytherapy of He-Ne, though low-intensity He-Ne laser intravascular radiation therapeutic apparatus has been made very small and exquisitely, therapeutic effect is also good, but this instrument is because laser generator itself has bigger volume (hundreds of millimeters long are generally arranged), further miniaturization has not had too big leeway, next He-Ne laser therapeutic apparatus band high-tension electricity, and power consumption is big, wavelength is single, and therapeutic effect still seems when being used for intravascular irradiation weak point.
The object of the present invention is to provide that a kind of volume is little, the semiconductor visual laser endovascular radiating instrument of little power consumption, adjustable power.
The present invention is achieved in that it comprises laser generator power supply (4), laser generator (5), laser generator mount pad (3), current controller (12), optical fibers (8), medical connector (9), medical clamper (10), laser accunputure head (11), lens (1), bonder (7).Select for use the semiconductor laser generator as the lasing fluorescence source, the tube core scioptics are imaged on the fiber end face in the bonder, make the coupling of laser and optical fiber, enter the laser accunputure head that is transferred to the other end in the optical fiber, during use the laser accunputure head is injected the medical retention needle guard, insert in the blood vessel and make laser direct irradiation blood, thereby changed hemorheological character, promote blood circulation, reached multiple diseases such as treatment cardiovascular and cerebrovascular vessel.
Can adopt the visible light semiconductor laser generator between 0.4～0.7 micron of the output wavelength in actual applications, connection-controller changes the output that the control electric current can be regulated laser generator easily in its control extremely, to satisfy different patients' treatment needs.Head can adopt disposable laser accunputure head, is connected with optical fiber by medical clamper, changes very convenient.
Compare with traditional laser therapeutic apparatus, the present invention has possessed series of advantages: at first, because having adopted the semiconductor laser generator is lasing light emitter, volume, weight can significantly reduce, can put into pocket during tools for doctor home visit fully and carry use, solve the conventional laser therapeutic instrument and can't carry a difficult problem of paying a home visit; Secondly, its running voltage has only several volts, and operating current has only tens milliamperes, gets final product work with aneroid battery, and little power consumption is not subjected to power limitations; The 3rd, its output can be regulated easily, can satisfy the treatment needs of the different state of an illness of different patients; The 4th, adopt disposable laser accunputure head convenient and healthy, can avoid cross infection.More than various advantages, the present invention is had been widely used.
Below in conjunction with accompanying drawing the embodiment of the invention is elaborated:
Fig. 1 is a structural representation of the present invention.
Outsourcing or self-control dedicated semiconductor laser generator power supply are connected on the laser generator peace On three electrodes of the laser generator 5 in the dress seat 3, add the work electric current, laser takes place The visible laser that the tube core 2 of device 5 sends can separate with laser generation mount pad 3 Coupler 7 fronts place lens 1, the fiber end face 6 in lens 1 and the coupler 7 Relative position be relatively-stationary after adjusting. Coupler 7 and laser generator peace Dress seat 3 adopts plug to connect or is threaded. Tube core 2 scioptics 1 are imaged on coupling Close on the fiber end face 6 in the device 7 light that laser generator 5 sends, just efficiently coupling Enter optical fiber 8, and reach on the medical connector 9 through optical fiber 8, by unscrewing or twisting Tight medical retaining device 10 can take off or connect laser accunputure head 11, whole instrument easily In use, the control that is adjusted in laser generator 5 by current controller 12 is extremely gone up Operating current, can determine easily the laser of the treatment usefulness that laser accunputure head output is required Generator power.
Embodiment: adopting TO29211 semiconductor laser generator is the lasing fluorescence source, it can produce wavelength is 0.67 micron visible laser, homemade semiconductor laser generator electric current 4 is connected three electrodes of laser instrument, in the control extremely of laser generator, connect a controllable silicon current controller, selecting the optical fiber core diameter for use is 0.13 millimeter multimode fibre, fiber coupler is a plug-type, medical connector also can be selected plug-type for use, clamper is the taper thread clamper, and the diameter of bore of laser accunputure head is 0.6 millimeter.Earlier common medical retention piercing needle is lunged blood vessel during use, from its sleeve pipe, extract out after the nook closing member, change laser accunputure head of the present invention, utilize laser direct irradiation blood, reach therapeutic purposes.Through practice test, this kind instrument all has good effect to the treatment cardiovascular and cerebrovascular disease.
