Description
Technical field
This utility model relates to the laser beautifying apparatus, be specifically related to a kind of single-stage laser beautifying machine that is contained in the joint arm, belong to International Classification of Patents A61B18/00 " to human body or transmit surgical instruments, device or the method for on-mechanical form energy from human body " technical field.
Background technology
Several years in past is at international and domestic popular a kind of laser beautifying machine, and it is through generally being made of seven 45 ° of completely reflecting mirrors, the articulate arm that can rotate freely, with the Laser Transmission of Q-Q-swith laser Q output to human body.Because the light path length overall of joint arm is near 2 meters, the angle of divergence that requires laser is below 5 milliradians.Otherwise will be in the light owing to the joint arm clear aperature is limited.The angle of divergence that reduces laser need be a cost to sacrifice lasing efficiency.Add the loss of 7 reflecting mirrors, so the logical luminous efficiency of joint arm is generally below 80%.And joint arm is in active procedure, and optical axis direction must not change.This just requires the precision of processing and assembling very high.In order to overcome above shortcoming, developed that both at home and abroad laser instrument is contained in structure in the joint arm.Yet because laser instrument does too greatly, be contained in the joint arm, joint arm just bloated one pregnant.This has just influenced the motility of joint arm motion.Nor it is attractive in appearance.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of laser design meticulous, is contained in not make joint arm give prominence to bulge in the joint arm, to guarantee joint arm laser instrument motility, that have small-sized joint arm.
The purpose of this utility model is achieved through the following technical solutions.
A kind of laser instrument that has small-sized joint arm comprises joint arm galianconism, long-armed and support, joint arm galianconism and long-armed hinged, long-armed lower end is connected on the support pivotally, long-armed tail end is equipped with a counterweight, joint arm galianconism external diameter unanimity, and the lower end connects 3 45 ° of completely reflecting mirrors; Meticulous Q-switched laser is positioned at the joint arm galianconism inside of external diameter unanimity, on the front; Wavelength shifter is equipped with in the laser instrument front portion, and the joint arm front end is equipped with the rod-pulling type focus head.
Described laser instrument is matrix with the aluminium alloy bars, and the afterbody of laser instrument is equipped with the total reflection mirror holder, and water pipe is equipped with in the bottom of laser instrument; In the matrix, wavelength shifter and 650nm quasiconductor are equipped with the light path indicator in the front portion, and the rear portion is equipped with Q-switch, adjusting Q crystal and adjustment rack thereof, and the middle part is provided with laser pump cavity, and Nd:YAG crystal bar and xenon lamp are housed in the laser pump cavity.External diameter as the aluminium alloy bars of matrix is 32mm.Wavelength shifter adopts dial-type 1064-532nm wavelength shifter.Laser pump cavity is diffuse-reflectance hard-pressed bale glass chamber, is filled with efficient diffuse-reflectance powder between the glass core of its cavity and shell, and the two end cap of this laser pump cavity and water contact portion adopt titanium alloy material to make.
This utility model all designs condenser, cavity mirror, adjusting Q crystal, cooling water circulation passage and small-sized 650nm in an aluminium alloy cylinder by external diameter 32mm with the 1064-532nm wavelength shifter of light path indicator, dial-type.Because it is very meticulous that laser design gets, and it is contained in the galianconism front end of joint arm, joint arm needn't be given prominence to a bulge, has guaranteed the motility of joint arm.On the other hand, although laser instrument designs very carefully, the Nd:YAG laser bar of the diameter 8mm that can pack into makes single-stage Q-switch laser pulse output energy not have greater than 500mj. both at home and abroad.This utility model is owing to having designed the tiny very high Q-Q-swith laser Q of energy of exporting of volume, and the joint arm of packing into can keep the unified profile of joint arm, has reduced the required precision of joint arm process and assemble.Enlarged range of application.

Among the figure: 1, matrix, 2, the total reflection mirror holder, 3, the Q-switch, 4, laser pump cavity, 5, with the light path indicator, 6, wavelength shifter, 7, water pipe, 8, the Nd:YAG rod, 9, xenon lamp, 10, water channel, 11, the lamp line passage, 12, the joint arm galianconism, 13, long-armed, 14, support, 15, counterweight, 16, laser focusing head, 17, laser instrument.
The specific embodiment
Referring to above-mentioned each accompanying drawing, have the laser instrument of small-sized joint arm, comprise joint arm galianconism 12, long-armed 13 and support 14, joint arm galianconism 12 and long-armed 13 hinged, long-armed 13 lower ending pivot shaft types are connected on the support 14; Long-armed 13 tail ends are adorned a counterweight 15.Joint arm galianconism 12 external diameter unanimities, the lower end connects 3 45 ° of completely reflecting mirrors and laser focusing head 16, and meticulous Q-switched laser 17 is positioned at the joint arm galianconism 12 of external diameter unanimity, by the bottom.
Laser instrument 17 is a matrix 1 with the aluminium alloy bars of external diameter 32mm, afterbody be equipped with total reflection mirror holder 2 and with outside water pipe connecting, lead, bottom dress water pipe 7; In the matrix 1, anterior dress wavelength shifter 6 and 650nm quasiconductor are with light path indicator 5, and the rear portion is equipped with Q-switch 3, adjusting Q crystal and adjustment rack thereof, and laser pump cavity 4 is established at the middle part, and Nd:YAG crystal bar 8 and xenon lamp 9 are housed in the laser pump cavity 4.
Total reflection is adjustable mirror holder 2 is on existing two bases that hold out against screw and two stretching screws, has increased by four lock-screws, to increase stability.
The design in meticulous high-effective concentration chamber is a core of the present utility model.The hard glass hard-pressed bale diffuse-reflective cavity of laser pump cavity 4 for forming by the particular manufacturing craft blowing.This chamber can be in 1000 watts of following operate as normal of injecting power.And the work of this machine only needs 300 watts.Improved reliability.Cancelled the oral siphon that of traditional use, the stainless steel waterpipe that is bumped in the matrix 1 has directly been linked to each other with the cavity two ends under the chamber.Though laser pump cavity 4 profiles are very little, can load the Nd:YAG laser bar 8 of external diameter 8mm, improved the output energy greatly.Water flow velocity is very high in the laser pump cavity 4, and pump light is evenly distributed, laser output facula circle.Laser pump cavity 4 two end cap and water contact portion are titanium alloy, have thoroughly solved common aluminum alloy and have been subjected to aqueous corrosion to pollute the problem of recirculated water.
The 650nm quasiconductor that this utility model adopts is with light path indicator 5 and be contained in matrix the place ahead dial-type 1064-532nm wavelength shifter 6, and be contained in rod-pulling type focus head 16 that the joint arm front end is used to change the focal beam spot size be I in first to file patent.
Referring to Fig. 1, after laser instrument, wavelength shifter etc. assembles, be contained in the joint arm galianconism 12 of external diameter 36mm forward end together.Post-brachial 4 the 45 ° of reflecting mirrors in joint are cancelled, and become the passage of water pipe and lead.The rod-pulling type focus head 16 that keeps 3 45 ° of reflecting mirrors of front end and the place ahead.
