The specific embodiment
Embodiment 1, and the present embodiment is a kind of optical fiber therapeutic instrument of capable of regulating laser focal, and when human skin tissue is treated, optical-fiber laser is by hands tool, and laser produces focus point, and human body skin interior tissue is treated.When human body skin interior tissue is treated, subcutaneous depth that can be different according to skin, adjusts the focus point position of laser.The focussing mechanism in the present embodiment with the focus point position of a capable of regulating laser, this focussing mechanism principle as shown in Figure 1:
Through illuminator 13, X shake mirror 1 and 2 reflections of Y shake mirror, form there is certain hot spot fiber laser beam 22 by optical focus mirror group 20, through Refractive focusing outside crystal 23 a bit, this point is exactly focus point 24, at this point, produces focus energy, and skin interior tissue is treated.On motor 9 with the threaded output shaft of tool, a nut 8 is installed on it, in order to make nut 8, be combined closely with the output shaft of motor 9, and the screw-threaded engagement time is long, in the present embodiment, nut adopts copper nut, on copper nut two sides, be processed with concave groove 16, in sliding sleeve 7, be equipped with focus lamp group 20, with gland 17 and clamp nut 18, be fixed in sliding sleeve 7.In the interior one end of sliding sleeve 7, be provided with to projecting inward interior along 19.In utilizing along 19, gland 17 and clamp nut 18 be limited in focus lamp group 20 in sliding sleeve 7.On one end end face of sliding sleeve 7, be processed with draw-in groove 21, the concave groove 16 on copper nut two sides matches with the draw-in groove 21 on the end face of sliding sleeve 7, when motor 9 energisings are rotated, copper nut just produces traveling priority, drive sliding sleeve 7 to slide in the interior generation of abutment sleeve 6, thereby the focus lamp group 20 in sliding sleeve 7 is subjected to displacement, has changed the position of focus point, reach the adjustable object of focus point that laser is treated on skin.
If Fig. 2 is the sketch of sliding sleeve 7 and nut 8, on one end end face of sliding sleeve 7, be processed with draw-in groove 21, the present embodiment adopts copper nut, on copper nut periphery, be processed with concave groove 16, concave groove 16 matches with draw-in groove 21, on motor 9 with the threaded output shaft of tool, nut 8 is the phase threaded engagement on screw thread and the screw thread output shaft of copper nut inner hole namely, when motor drives little axle to rotate, copper nut just produces traveling priority, and match with draw-in groove 21 by concave groove 16, drive sliding sleeve to produce mobile.
Respectively structural representation and the exploded view of focusing machine structure as shown in Figure 3 and Figure 4.As shown in Figure 4: X shake mirror 1 is arranged on pedestal 12 with Y shake mirror 2, the laser fiber 15 of outgoing laser beam is connected with pedestal 12 by optical fiber deck 14, the reflection seat 13 that reflecting optics is installed is connected with pedestal 12, the laser with certain diameter hot spot sends from laser fiber 15, by the reflecting optics on reflection seat 13, reflex on X shake mirror 1, laser reflexes to Y shake mirror 2 from X shake mirror 1 again, the interior focus lamp group that is fixedly equipped with of sliding sleeve 7, by programme-control, optical-fiber laser can be shaken to mirror 1 and the regular rotation of Y shake mirror 2 by X, the regular focus lamp group that reflexes to, there is the optical-fiber laser of certain diameter by the refraction of focus lamp group, generation has the focus point of fixed focal length, focus point is by the crystal of contact skin, drop on the skin interior tissue of human body.
On motor 9, with the threaded output shaft of tool, motor 9 is fixed in the hole of motor fixing seat 10, is fixed, and be connected with pedestal 12 by motor fixing seat 10 with locknut 11.On the screw thread output shaft of motor, copper nut is installed, the screw thread on the screw thread output shaft of the screw thread of copper nut endoporus and motor matches, and on the periphery of copper nut 8, is processed with concave groove.On one end end face of sliding sleeve 7, be processed with draw-in groove, concave groove on copper wire mother 8 matches with the draw-in groove on slip cap 7 end faces, when motor 9 drives little axle to rotate, copper nut 8 just produces traveling priority, concave groove on copper nut 8 matches with the draw-in groove on slip cap 7 end faces, drives sliding sleeve 7 to move in the interior generation of abutment sleeve 6.The interior focus lamp group that is fixedly equipped with of sliding sleeve 7, when sliding sleeve 7 is when abutment sleeve 6 generations are moved, focus lamp group is also just corresponding produces displacement, thereby makes the focus point producing by focusing also be subjected to displacement variation, thereby has reached the object of adjustment focal position.
In addition, magnetic pole 4 is also installed on the end face of slip cap 7, Hall element 3 is fixed by screws in pedestal 12, by coordinating of magnetic pole 4 and Hall element 3, produce the signal of telecommunication, feed back to main frame, host circuit can be by the rotation of programme-control motor 9, thereby reaches the object of controlling slip cap 7 and focus lamp group shift position.
