Technical field
This utility model relates to medical instruments field, particularly a kind of laser power therapeutic instrument of optical dynamic therapy.
Background technology
The effect basis of photodynamic therapy (Photodynamic Therapy, abbreviation PDT) is photodynamic effect, and this is a kind of photosensitization reaction of following biological effect that has oxygen molecule to participate in.Its process is the rayed by specific wavelength (scope), the photosensitizer that tissue is absorbed is excited, and the photosensitizer of excited state is the energy delivery oxygen supply, generate active very strong singlet oxygen, singlet oxygen again with adjacent biomacromolecule generation oxidation reaction, produce cell toxicant, and then cause cell impaired and even dead.PDT generally carries out in two steps, at first is to use photosensitizer to the patient, is that focal zone is carried out rayed then.
Photodynamic therapy (PDT) is international, domestic new a kind of effective methods for the treatment of diseases of carrying out use in recent years, it all is widely used in department of dermatologry, urology department, ophthalmology, oncology, department of obstetrics and gynecology, the department of stomatology, neurosurgery etc., such as photodynamic therapy the common acne of department of dermatologry is had tangible curative effect.Openly be used for the treatment of the employed photodynamic therapeutic instrument of dermopathic photodynamic therapy (PDT) in the prior art and mainly pass through the red-light LED scattered light as light source, large tracts of land is carried out at the position that scribbles photosensitizer organize external exposure, because what adopt is that the LED scattered light is organized external exposure, in the irradiation process to the patient, untoward reaction be may occur, burn feeling, scratchiness or sensation of pricking partly had such as normal skin; Treatment finishes the back light position and erythema, edema, pain, part patient often occur even comparatively serious reactive acne, Secondary cases pigmentation and exfoliation may occur.In addition according to experimental results show that, blue light has stronger inhibitory action by the light principle of dynamics to the important step " propionibacterium acnes " in the acne morbidity than HONGGUANG, but because blue light wavelength is below 600nm, its to the penetration power of skin a little less than, can not reach the target function of organization degree of depth, cause the effect of blue light on the acne optical dynamic therapy not to be developed.
The utility model content
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art, provide a kind of can be accurately at the laser power therapeutic instrument of interstitial irradiation's target site.
For achieving the above object, this utility model provides following technical scheme:
A kind of laser power therapeutic instrument comprises laser beam emitting device and the optical fiber that can produce the 200-1500nm wavelength light, and an end of described optical fiber is connected with laser beam emitting device, and the other end is for importing the treatment termination in the tissue.
In the above-mentioned laser power therapeutic instrument, described treatment termination is an end of optical fiber, and this end can directly insert and carry out rayed in the tissue.
In the above-mentioned laser power therapeutic instrument, described laser power therapeutic instrument also comprises one-time treatment optical fiber and adapter, and described one-time treatment optical fiber is connected with an end of optical fiber by adapter, and the other end of optical fiber connects laser beam emitting device.
In the above-mentioned laser power therapeutic instrument, the light that described laser beam emitting device sends is HONGGUANG or near infrared light, and the optical source wavelength of described HONGGUANG or near infrared light is 600-900nm, the output power density 1-150mW/cm of described HONGGUANG or near infrared light
2
In the above-mentioned laser power therapeutic instrument, the light that described laser beam emitting device sends is blue light, and described blue light source wavelength is 400-490nm, described blue light output power density 1-150mW/cm
2
In the above-mentioned laser power therapeutic instrument, the core diameter of described optical fiber and one-time treatment optical fiber is 1-5000 μ m.
In the above-mentioned laser power therapeutic instrument, the laser of the specific wavelength that laser beam emitting device produces need not penetrate outer the stopping of target tissue and organize medium, arrive the target location by optical fiber, laser light energy is directly acted on the target tissue realize internal radiation, increase light power curative effect, reduced the side effect of light power external exposure.
Compared with prior art, the beneficial effects of the utility model: this utility model imports to the target tissue by optical fiber with luminous energy and carries out local internal radiation, the impaired side effect of normal surrounding tissue in the time of can effectively avoiding present light motor tissue external radiotherapy disease is simultaneously by shortening the effect that irradiation distance reaches increases curative effect.In addition, introduce target tissue by the location of the light (such as blue light) below the optical fiber wavelength 600nm that penetration power is more weak, reduced the obstruct medium between itself and the target tissue, shortened its operating distance, thereby solve the problem that it can not be applied to optical dynamic therapy a little less than because of penetration power, though give full play to a little less than the following light penetration power of wavelength 600nm, the special role advantage is arranged, widened the usage range of optical dynamic therapy.The use of one-time treatment optical fiber meets the health care standard, effectively reduces patient's use cost.
