The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments that can be derived by one of ordinary skill in the art from the embodiments given herein are intended to be within the scope of the present invention.
As shown in fig. 1-2, the method for converting a treatment pattern based on an adjustable spiral-shaped laser spot according to an embodiment of the present invention includes the following steps: s1, selecting a reference laser beam output by the carbon dioxide therapeutic machine, and selecting a focusing lens and a therapeutic head which are matched with the reference laser beam; s2, arranging a light spot conversion device at the output end of the reference laser beam, wherein the reference laser beam sequentially passes through the light spot conversion device, the image scanner, the focusing mirror and the treatment head; s3, correspondingly controlling the light spot conversion device through a microprocessor in the carbon dioxide therapeutic machine, so that the reference laser beam passing through the light spot conversion device is converted into a spiral line type laser light spot with a proper size, and the spiral line type laser light spot generates a therapeutic figure matched with the therapeutic part of the patient through the figure scanner, the focusing mirror and the therapeutic head in sequence.
In the method, a plurality of light spots of a reference treatment laser beam can be converted into spiral light spots through the swinging of a first reflecting mirror 1 and a second reflecting mirror 3 of a light spot conversion device, the first reflecting mirror 1 and the second reflecting mirror 3 are respectively driven by a first galvanometer motor 2 and a second galvanometer motor 4 by taking the spiral light spots as a reference, and the galvanometer motors have the characteristics of high response speed, high swinging frequency, accurate and controllable rotating angle and the like. Different reference voltages can rotate the galvanometer voltage by different angles. The circuit adopts a 16-bit chip LTC2642, and the chip is controlled by a program to accurately output a voltage from-5.00V to + 5.00V. According to the characteristics of the galvanometer motor, the output light path moves by 1mm every 0.2V voltage, the light path can move by +/-20 mm by +/-5V voltage, and the reflectors fixed on the rotating shafts of the two galvanometer motors are concentric, but the axial direction is 90 degrees.
In the method of the invention, the pattern scanner can scan the two-dimensional pattern of the treatment area of the patient and output the corresponding treatment pattern by taking the spiral-line-shaped light spot as a new light spot point through corresponding control.
In the method of the invention, the focusing mirror focuses the laser beam and can keep the treatment receiving surface exactly as the laser focus by matching with the treatment head.
In order to facilitate understanding of the above-described technical aspects of the present invention, the above-described technical aspects of the present invention will be described in detail below in terms of specific usage.
When the treatment device is used specifically, a laser beam with a single-point laser spot of 0.12mm is selected as a reference treatment laser beam, and a matched focusing mirror and a treatment head, namely a 50mm focusing mirror (with a focal distance of 50 mm) and an F50S treatment head (with a skeleton length of 50 mm) are selected, so that the laser beam with the single-point laser spot of 0.12mm can keep a treatment receiving surface just as a laser focus, and as shown in fig. 3, when the adjustment is not performed by using a spot conversion device, a treatment pattern formed by a 0.12mm laser spot 5 is finally used.
When the treatment light spot needs to be enlarged, as shown in fig. 4, when the laser light spot 6 with the diameter of 1.3mm is used, the corresponding focusing lens and the treatment head need to be replaced, when the treatment part of a patient to be treated has a plurality of positions and the condition is not uniform, different light spots can be judged and selected according to the corresponding condition, and thus, the replacement of the focusing lens and the treatment head is troublesome, and time is wasted.
As shown in fig. 5, the laser beam with a single-point laser spot of 0.12mm is still used as the reference treatment laser beam, and a spot conversion device is added at the output end of the laser beam, when the treatment spot needs to be enlarged, for example, a 1.3mm spiral laser spot 7 is needed, a corresponding value can be set on the control panel of the carbon dioxide treatment machine, and the microprocessor in the carbon dioxide treatment machine can correspondingly control the spot conversion device to work, so as to obtain the spiral laser spot with the required size. The control of the light spot conversion device is based on an Archimedes spiral formula, a polar coordinate equation r = a + b theta, a and b are real numbers, r is a designated radius, a is the distance from a starting point to a polar coordinate origin, b is a numerical value which is correspondingly increased along with the increase of the unit angle r of the spiral line, the change parameter a is equivalent to the rotation spiral, and the parameter b controls the distance between two adjacent curves. Defining coordinates (0, 0) as starting point, setting a =0, b =0.035, the planar cartesian coordinate equation of the archimedean spiral as:
c = r × cos (θ), D = r × sin (θ), where the value of C is the amount of movement of the reference treatment laser beam in the X direction, and the value of D is the amount of movement of the reference treatment laser beam in the Y direction.
To sum up, thereby can set up different parameters according to the treatment needs and obtain the not helical line type laser facula of equidimension, form the treatment figure that needs with the helical line type laser facula as the light spot, then this process facula size can freely be adjusted, need not change focusing mirror or treatment head, easy operation, low cost, helical line type laser facula is the helical line type simultaneously, it is heat protection zone 8 for there is no light zone in the helix, for the solid light spot of equal size, it acts on the skin, there is the skin protection zone, it is little to the skin damage, painful sense is weak, be favorable to postoperative to resume, the recovery cycle is short.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
