Description
Technical field
The present invention relates to medical instruments field, specifically be utilize optical fiber technology in body, inject light energy, can be used for diagnosing, the medical laser acupuncture of a kind of plug and play of acupuncture and treatment.
Background technology
Laser itself is a kind of energy, and coherence, directivity are fine, and intensity can be very high, and output wavelength and energy precision are controlled.For example, utilize the blood of argon laser irradiation, can kill HIV (human immunodeficiency virus) through extracorporeal circulation; The characteristic spectral line of laser spectrum can be used to diagnose and judge the therapeutic effect of medicine.So laser not only can be used for the treatment of, can also be used for diagnosis.At present, laser has been used for treating for skin disease, or the medical application on nearly surface, and is for example in the ophthalmology and the department of stomatology, quite universal.It is but very difficult that but laser enters human body, and this is that light is difficult to enter in the body because the organ of human body and tissue are opaque to light.
Exploitation the earliest light to be introduced intravital be the endoscope of being made by fibre bundle.Now, the body of this endoscope probe can be accomplished only 1 millimeter of diameter, and the optical fiber pixel reaches 10,000, and tens microns of resolution mainly still are used for the diagnosis of diseased region.The capsule type endoscope that has video camera of newly-developed is done very for a short time, and (φ 0.9 * 2.3cm), also only can be used for diagnosis, and very expensive.It is a lot of that the weak laser irradiation is used for the treatment of research, and development potentiality is arranged very much.Being used for interior therapeutic, at first is laser acupuncture and moxibustion.What develop the earliest is semiconductor laser acupuncture device and He-Ne Lasers acupuncture and moxibustion instrument.This has had corresponding apparatus to sell in last century end, but curative effect is undesirable.For example, three in semiconductor laser acupuncture device one cover of former Changchun Institute of Ray Machine research and development: the semiconductor laser of band collimator profile such as pen, light output situation and a power supply can be detected in a fluorescence pond.The major advantage of this laser acupuncture and moxibustion is to be needled into skin, thereby FFI worry, does not also have the worry of twinge.But do not grow up, reason has two, the one, and the scattering of tissue and absorb to make that to enter intravital light very weak also is difficult to focus on.The 2nd, select the reasonable wavelength of printing opacity, can seldom heat effect be not good because of absorbing yet, do not reach the purpose of acupuncture.He-Ne Lasers has the effect of blood circulation promoting and blood stasis dispelling.Scrutinize its mechanism and find it is that the deformability of erythrocyte has increased.Be used for intravascular irradiation and also instrument arranged.The low level laser intravascular irradiation of beginning in 1984 has obtained successful application.The model of Anbui Optical Machinery Inst., Chinese Academy of Sciences's exploitation is the He-Ne laser inner blood vessel irradiating instrument result that application obtains in the occlusive vascular disease treatment in limbs of YNH0-A type.It still is a problem that but optical fiber enters intravital method, and the insertion of optical fiber and fixing all be not easy is difficult to be extensive use of and promote.
For luminous energy is entered in the body by optical fiber, utility model patent CN00205098.6 " a kind of laser needle acupuncture needle " utilizes the paracentesis trocar that uses in the laser therapy instrument, its improvements are successively acupuncture needle and optical fiber pin to be inserted paracentesis trocar, acupuncture needle that inserts or the design of optical fiber pin have needle stand, are fixed by round platform that has draw-in groove and corresponding bayonet lock.But be to use the puncture catheter needle, all do not solve the insertion and the fixed problem of optical fiber.This acupuncture needle also fails to promote till now, and following some reason is arranged:
1, after this laser needle acupuncture needle is experienced the acupuncture point with the catheter needle that contains acupuncture needle earlier when operation, pull out acupuncture needle again, insert the optical fiber pin, it is loaded down with trivial details operating.And, if be tight fit between acupuncture needle and the puncture conduit, when pulling out, must extract body fluid out; Even be not tight fit, may extract body fluid out yet.Because an aperture that is not less than 100 microns is arranged at the needle point place.When next step inserts optical fiber, no matter whether push the body fluid of extraction again, all accident may appear.2, optical fiber add the cover be routine techniques, be the general knowledge of professional.For special applications, add the multilamellar cover usually.Therefore, the cover that adds for medical laser acupuncture also should have special requirement, for example requirement of caliber and rigidity, the requirement of pine cover and tight cover.This patent is not mentioned the specific (special) requirements that consider to sleeve pipe.3, this laser acupuncture and moxibustion needle point is a circular cone, and optical fiber pin end face is a flat-top from figure.Promptly use standard quartz optical fiber, the diameter minimum also has 110 microns.The pain of thrusting human body can be bigger.And if optical fiber is naked fibre, the danger that fractures is arranged, also be difficult to affirmation and whether put in place.If the fibre ribbon covering can increase the overall diameter of laser accunputure, thereby increase patient's pain perception.If optical fiber can arbitrarily inject and extract, require the polishing of catheter needle inner surface, and be certain to keep certain clearance, this causes more uncertain factor to exist.Although statement is disposable use, for keeping easy to use and requirements sanitation and hygiene, cost has and increases considerably.4, the disk of band draw-in groove newly designs and to add trade union somewhat expensive, because optical fiber technology belongs to microtechnic.5, this utility model patent is at acupuncture, and working range is little and be difficult to obtain use.
On the other hand, from the development of guide technology, in the past the target of pursuing was can bending and motility, made luminous energy arrive the place that needs through the path of bending, guaranteed that simultaneously optical fiber can not fracture and light leak.The outer catheter of optical fiber is plastics or the most suitable this requirement of nylon.Even strengthen with rustless steel for submarine optical fiber cable, also be by the conduit of braided steel wire, make it possible to bending.At present, all optical fiber all are to be rolled into the cartridge type transportation, have utilized the flexible character of optical fiber exactly.But when barrier can not be walked around, can only by penetrate, when transmission, scattering or diffraction transmission, how to control with making and used up just to become a technical problem that needs to be resolved hurrily, for example, need inject light when reaching therapeutic purposes when human body, need a kind of apparatus that can make things convenient for the application of force and accurately arrive diseased region with beeline.Steel thimble optical fiber among the present invention has adopted annealing to increase its toughness, and quenching increases its stiffness, is tight fit between sleeve pipe and the optical fiber, or forms the solid composite structured optical fiber with adhesive cures.Laser accunputure by the manufacturing of this steel thimble optical fiber can accurately arrive diseased region with the shortest air line distance.
