Description
Technical field
The present invention relates to Medical Laser Technology field, be specifically related to a kind of carbon dioxide laser therapeutic apparatus terminal output facula actuator.
Background technology
The advantages such as laser has good directionality, and monochromaticity is high, and coherence is good.Have a wide range of applications in laser processing technology, laser medicine and photon biology, the field such as laser detection and measurement technology, laser holography, laser spectral analysis technology, nonlinear optics, ultrafast laser, laser chemistry, quantum optices, laser radar, laser guidance, laser isotope separation, laser controllable nuclear fusion and laser weapon.The laser beam that medical Laser Treatment Machine needs will have different beam diameters and the little angle of divergence, and the lasing beam diameter that same laser instrument sends is constant, and has certain angle of divergence, directly can not meet the requirement of clinical practice.Medical carbon dioxide laser therapy aparatus laser beam used generally need make laser beam spot diameter diminish through focusing, after power density uprises, could be used for cutting, solidify, the operation such as vaporization.
The principle of carbon dioxide laser focusing lens is according to clinical demand, selects the convex lens of different focal, the laser beam that the laser beam allowing laser instrument send varies in size by obtaining spot diameter after convex lens focus at concave lens focus place.Conventional convex lens has 50mm focal length and 100mm focal length two kinds, and the laser beam spot obtained by 50mm focal length focusing lens is little, and power density is high, is more suitable for tissue fine cut.
In process of clinical application, doctor needs according to the demand of different patient, and the situation such as pathological tissues as all ages and classes patient, different lesions organize patient, different area size adopts the laser beam spot of different-diameter to treat.Existing carbon dioxide laser therapeutic apparatus equipment lacks the parts of special adjusting laser beam hot spot, doctor is when using existing carbon dioxide laser therapeutic apparatus to treat, in order to obtain the laser beam spot of different-diameter, have to manually to change the focusing lens of different size, or the distance manually changing treatment handle and treated tissue changes the size of laser beam spot diameter.
The focusing lens of manual replacing different size changes the size of laser beam spot diameter, there is following weak point:
(1) doctor is when manually changing the focusing lens of different size, easily brings in Curing circumstance by antibacterial, can not meet the requirement of doctor needs sterile working when treating.
(2) doctor over the course for the treatment of, can not find applicable focusing lens very soon, needs the focusing lens constantly changing different size, not only inconvenient operation, and lose time.
(3) for meeting treatment needs, the focusing lens being equipped with different size for the different focusing lens of plurality of specifications respectively is not only needed to treat head, the focusing lens treatment head to being equipped with also is needed to carry out disinfection and deposit, not only increase armarium cost and medical treatment cost, and add the workload of medical worker, therefore, for the focusing lens treatment head of the focusing lens outfit different size of different size does not meet reality.
The manual distance changing treatment handle and treated tissue changes the size of the diameter of laser beam spot, although simple to operate, but still there is following weak point:
(1) doctor can only rely on operating experience, after subjective judgment, the distance that manual operation changes treatment head and treated tissue changes the size of laser beam spot, can not size that is objective, scientifically adjusting laser beam hot spot, is also difficult to obtain the laser beam spot being applicable to treating.
(2), in the process of manual moving treatment head, treatment head can be changed to the distance needing treated tissue, not meet the requirement of clinical delicate procedure.
To sum up state institute, existing carbon dioxide laser therapeutic apparatus is only adopted to treat, doctor can not science, fast, obtain the hot spot of different lasing beam diameter easily, therefore, need to develop a kind of parts that can be used in carbon dioxide laser therapeutic apparatus carrying out regulate hot spot, to realize doctor in the treatment, focusing lens need not be changed, just can science, fast, obtain different lasing beam diameter easily, the carbon dioxide laser beam hot spot of uniformity, save doctor in operation process, to the time and efforts of equipment operating and adjustment, more time and efforts can be put and be gone over the course for the treatment of by doctor.
Summary of the invention
