The specific embodiment
Below in conjunction with drawings and Examples, the utility model will be further described: as shown in Figure 1, 2, a kind of laser therapy hands tool of adjustable spot size, it is characterized in that: tailstock 2 is fixed on body 1, annular circuit board 14 is fixed on tailstock 2, and circuit board 14 has the optocoupler of detection position; On body 1, be fixed with protective cover 4; Ball 13 is installed on protective cover 4, and ball 13 is supported by Compress Spring 12; Handwheel 3 is fixed on body 1 and around body 1 rotation, has one group of hole 15 of use, location and the breach 16 of 2 logical light on handwheel 3; Handwheel 3 is fixed together with cam 5; Described cam 5 drives the lens barrel 10 being located in body 1 endoporus to move; Plus lens 11 is fixed in lens barrel 10; Minus lens 9 is fixed on body 1, and minus lens 9 front ends are equipped with protection eyeglass 8, and body 1 front portion is provided with a sleeve 7 that kuppe 6 is housed.
Described ball 13 is engaged in the hole 15 of locating use on handwheel 3.
Described optocoupler is slot optical coupling, be provided with 7 gears, and the optocoupler of 7 gears is divided into two groups, be placed in two regions, while rotating handwheel 3, there are 16, one groups of optocouplers of being responsible for even numbers gear of a corresponding handwheel breach in each region, another group is responsible for the optocoupler of odd number gear, the distance 6.6mm between each adjacent optocoupler; Position angle is followed successively by 314o, 56o, 292o, 35o, 270o, 13o, 237o.
When described handwheel 3 rotates, the breach 16 on handwheel 3 is alternately placed in the middle of the optocoupler 17 of diverse location, make optocoupler conducting, and other optocoupler is all blocked, and like this, provides the corresponding spot diameter signal of conducting optocoupler.
During use, hands tool is connected with light-conducting arm by the screw thread on body 1, when laser is when light-conducting arm is launched, and at skin surface, forms hot spot by the plus lens 11 in body 1 and minus lens 9; While rotating handwheel 3, the conduction by cam 5 with moving lens barrel 10, produces plus lens 11 mobile, thereby changes the diameter of skin surface treatment hot spot.
During work, the air-flow high-speed mobile that the volatile matter on skin can produce when burning, kuppe 6 and protection eyeglass 8 form an approximate airtight space, can make most of air-flow to hands tool diffuse outside, alleviate the pollution of volatile matter to eyeglass.
Treatment hands tool is furnished with spot sensor, hot spot is changed to size and pass in time single-chip computer control system energy density is adjusted automatically, can guarantee that under different spot diameters, energy density is identical, thereby guarantee therapeutic effect.As shown in Fig. 3-9, by a rotation hand wheel 3 with ball 13 location, drive cam 5 synchronous rotaries, during cam 5 rotation, the lens barrel 10 that drive includes a slice plus lens 11 moves along the optical axis of body 1 endoporus, when lens barrel 10 is positioned at diverse location, by light-conducting arm penetrate and the collimated laser beam that passes through hands tool through the combined effect of plus lens 11 and the fixing minus lens 9 of the other end, at skin surface, form the hot spot of different-diameter, thereby complete different treatments; The a certain position of lens barrel 10 or plus lens 11 is corresponding a kind of spot diameter only, by the requirement for the treatment of, need to provide the position signalling of 7 spot diameters such as 2mm, 3mm, 4 mm, 5 mm, 6 mm, 7 mm, ∞ (8mm is directional light).
The selection of spot size is determined with the position of breach 16 on 7 fixing optocouplers and handwheel 3, optocoupler is divided into two groups, be placed in two regions, there is a corresponding handwheel breach 16 in each region, be responsible for even numbers for one group, another group is responsible for odd number, can increase the distance between adjacent optocoupler, during handwheel rotation, breach 16 on it is alternately placed in the middle of some optocouplers of diverse location, make this optocoupler conducting, and other optocoupler is all blocked, like this, provide the corresponding spot diameter signal of conducting optocoupler.
As shown in figure 10, laser hands tool needs seven file location sensors, and each gear will have corresponding analog quantity to determine corresponding gear, adopts analog output, only needs three lines.Seven file location sensors adopt contactless mode, and contactless position sensor utilizes the conducting and the binary condition of ending to come alternative switch of optocoupler C, E joint, because it does not have the contact of contact, therefore extend its service life.
Its principle is described as follows:
Each gear of seven file location sensors consists of an optocoupler and two resistance respectively, and the outfan of seven gears is connected to a bit, meets altogether a pull-up resistor R8.When a gear in seven file location sensors is worked, other gear is not worked, and that is to say the optocoupler secondary side conducting of work gear, the secondary side cut-off of other gear optocoupler of not working.For example: when the gear of OP4 is worked, i.e. the C of OP4, E joint conducting, other optocoupler is not worked, and now the equivalent circuit of whole seven file location sensors is as shown in Figure 11-12; If ignore optocoupler OP4 secondary side C, E, save pressure reduction, whole in fact circuit is equivalent to the series connection of R8 and R41.The output of whole circuit is equivalent to the series connection dividing potential drop output of R8 and R41.During the work of each gear R8 will with corresponding gear electric resistance partial pressure, reasonably select the resistance of R8, R11, R21, R31, R41, R51, R61, R71 just can obtain the voltage corresponding with concrete gear at outfan.This voltage, give CPU and carry out A/D conversion, thereby obtain the concrete gear information of seven file location sensors.
Resistance R 1, R2, R3, R4, R5, R6, R7 are optocoupler primary side current-limiting resistances, and the primary side of all optocouplers is all the time all in work, and optocoupler will be selected slot optical coupling, needs the optocoupler of work not add and block between the groove of slot optical coupling; The optocoupler that does not need work adds and blocks between the groove of optocoupler.When seven file location sensor rotations are during to certain gear, between the groove of this gear optocoupler, do not add and block, between the groove of other optocoupler, must add and block.Blocking with not blocking is to be completed by mechanical part.
And resistance R 1, R2, R3, R4, R5, R6, R7 are all current-limiting resistances, are chosen as 470 Ω.Resistance R 8, R11, R21, R31, R41, R51, R61, R71 will determine according to each gear output voltage.Each gear output voltage just can be selected divider resistance correspondingly after having determined.Set R8=20K Ω.Mapping table between gear, divider resistance, output voltage is as follows:
| Gear | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
| Resistance | R11=3K | R21=6.8K | R31=15K | R41=27K | R51=43K | R61=75K | R71=150K |
| Output | 0.65±0.2V | 1.27±0.2V | 2.14±0.2V | 2.87±0.2V | 3.41±0.2V | 3.95±0.2V | 4.41±0.2V |
Optocoupler position is as following table:
| Gear | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
| Optocoupler | OP1 | OP2 | OP3 | OP4 | OP5 | OP6 | OP7 |
| Position angle | 314o | 56o | 292o | 35o | 270o | 13o | 237o |
Circuit board inside radius: 13.6mm, outer radius: 20.3mm.
