At present, known Medical C O
2In the laser transmission apparatus, CO
2The transmission of laser is to finish with the articulated type light-conducting arm.The articulated type light-conducting arm is to reflect the laser of delivering in relays mutually by the completely reflecting mirror that 5～7 faces are installed on the oscillating bearing in air, changes the direction of propagation of light, implements CO
2Laser surgery.Because light reflected can only be transmitted by straight line, adds the physical dimension reason of articulated type light-conducting arm, can not carry out the CO of body cavities (natural openings)
2Laser therapy.Obviously, owing to lack gentle type transmission medium, and make the higher CO of human cell tissue absorption efficiency
2The application of laser is subjected to certain restriction.
Silver halide polycrystalline infrared optical fiber is as a kind of transmission CO
2The flexible optical fibre material that laser activity is preferable has all successively been carried out deep basic research in world developed country as countries such as Russia, Japan, Germany, and has been carried out optical fiber type CO
2The experimental prototype trial-production of laser scalpel, and carried out animal experiment.In previous research work, successfully made silver halide fiber formula CO
2Laser scalpel (application number 00218178.9), and above-mentioned optical fiber scalpel has successfully been carried out animal experiment and clinical practice tested, operative site relates to human body natural openings or the interior CO of shallow table tract such as oral cavity, larynx, gynecological, anorectal section
2Laser surgery treatment, but the scalpel cost of all making with silver halide fiber is higher.
The purpose of this utility model is to provide a kind of flexibility transmission CO that is connected the outfan of articulated type light-conducting arm
2The silver halide fiber laser surgery cutter head of laser, the Laser Transmission direction of articulated type light-conducting arm output realizes turning to by the geometry variation of real core fibre, it can not only finish collinear operative treatment as the articulated type light-conducting arm, but also can implement the CO of body cavities inwall by means of the flexibility of optical fiber
2Laser surgery treatment, manufacturing cost can be significantly less than the silver halide fiber formula CO that the full gloss fibre is made
2Laser scalpel.
The purpose of this utility model is achieved in that and connects a silver halide fiber operation cutter head bonder that on the terminal delivery outlet of articulated type light-conducting arm silver halide fiber operation cutter head is connected on the bonder by the joints of optical fibre.The importation links to each other by the flexible metallic hose and the focus lens group of metal connecting piece and output in overall optical estate agent art cutter head.In optical fiber scalpel head part, silver halide fiber special joint (joints of optical fibre standard that the FC optic communication is used with the standard or the SMA general measure instrument of the joints of optical fibre), fixed mount, the optical fiber lock screw, fixed mount, flexible metallic hose links to each other successively, and the end of flexible metallic hose is connected with lens mount, and infrared focus lens group is installed in the lens mount.In the structure of this silver halide fiber operation cutter head, flexible metallic hose can carry out suitable bending according to purposes, to reach the laser therapy of non-rectilinear direction, the diameter of lens mount is 4～5 millimeters, is adapted at the chamber wall treatment that human body natural openings position such as oral cavity, larynx, vagina, anus and rectum etc. are located.
Owing to adopt above-mentioned scheme, can remedy the tract inwall that the articulated type light-conducting arm can't finish and the CO at turning
2Laser therapy makes CO
2The same treatment of implementing body cavities by means of optical fiber of laser with other laser.
