TECHNICAL FIELD
[0001] The utility model relates to medical beauty technical field, concretely is related to a medical beauty equipment focus adjustable hand tool. BACKGROUND
[0002] The laser transmission structure of traditional medical laser equipment is usually composed of a laser, a fiber transmission system, a mirror, a focusing mirror and a light guide arm. Among them, the laser is the core component of laser generation, the fiber transmission system transmits the laser generated by the laser to the treatment site, the mirror and the focusing mirror are used to adjust the direction and focal point size of the laser, and the light guide arm guides the laser from the fiber transmission system and transmits it to the treatment site. When the laser emits laser, it is transmitted to the light guide arm through the fiber transmission system. In the light guide arm, the laser is transmitted to the treatment site by total reflection. In the treatment site, the laser interacts with the skin tissue, produces heat effect, photochemical effect and other effects, so as to achieve the purpose of treatment.
[0003] With the rapid development of "laser" in the medical and cosmetic industry and scientific research market, the demand for laser cosmetic equipment is growing. However, the traditional medical laser equipment is often affected by factors such as instrument vibration and temperature, and may deviate. Deviation may cause positioning failure of laser cosmetic surgery. When operating, due to the lack of stability of the doctor's hand-held equipment or the machine itself, a small vibration may occur in the process of guiding the laser from the fiber transmission system to the treatment site, which may affect the transmission direction of the laser and cause the beam to deviate; the change of temperature will affect the change of refractive index of the material, and then change the speed and path of light propagation, which may cause deviation in the process of laser transmission; in addition, in the transmission process of high peak power laser and middle and far infrared waveband laser, a multi-joint light guide arm is usually used to transmit the laser to the patient treatment site, in this process, beam deformation, divergence angle compression is the basic requirement of designing light guide arm, however, refractive movement is difficult to avoid, if not handled properly, it may also cause the beam to deviate; in addition, although the use of optical fiber to conduct laser energy can greatly improve the transmission efficiency of laser and reduce the complexity of the system, the transmission of optical fiber itself to optical signal may also have loss and dispersion problems, which may cause deviation in the process of laser transmission.
[0004] In addition, the conventional medical laser equipment has a complicated implementation and is not flexible in use when the equipment needs to be adjusted in focal length: for example, the focal length is adjusted by placing a lens of a certain focal length to compress the divergence angle of the laser; or the laser is reflected by means of a concave mirror to achieve the adjustment of the focal length; another commonly used method is to use a straight tube to adjust the hole, which needs to use a straight tube identical to the light guide joint arm connecting tube as an adjusting tube, and the adjustment and correction process is very troublesome and difficult to meet the needs of the operation. The structure is complex, and the offset phenomenon is prone to occur through the reflecting mirror, light guide arm and other components.
[0005] In addition, the conventional medical equipment can only be used with specific laser equipment, limiting its application range. Content of the utility model
