The specific embodiment
Fig. 1 is this utility model structural representation, this utility model side bright dipping laser fiber structure comprises that an end is that the joints of optical fibre 5, the other end are the terminal medical silica fibre 1 of laser output, the terminal optical fiber connector of laser output is configured to inclined-plane 2, the laser stray fiber axis of transmission is penetrated, simultaneously optical fiber connector also socket inclined-plane 2 is enclosed in the intravital optical fiber medicated cap 3 of air chamber.Further, also be provided with operating grip 4 on the optical fiber 1, the distance of operating grip 4 and optical fiber connector is greater than the length of matching used endoscope with it.When treatment is used, to have of the through hole insertion of the optical fiber 1 of optical fiber medicated cap 3 by endoscope, optical fiber connector is sent to therapentic part, the joints of optical fibre 5 of laser instrument emitted laser through being connected with laser couplers transmit laser coupled in optical fiber 1, laser passes the output of optical fiber medicated cap 3 side direction in the 2 places total reflection of the inclined-plane of optical fiber connector.The operator can spur or rotating operating handle 4 drive fiber-optic outputs put in, extract out or rotate, and light shines the different parts of tissue.
This utility model optimized technical scheme is that the optical fiber connector grinding and polishing is become inclined-plane 2, the normal on inclined-plane 2 and the angle of shaft axis of optic fibre are designed to 49 °～70 °, make the light that laser beam comprised that is transmitted wavelength all produce total reflection, and the emergent light of propagating along shaft axis of optic fibre penetrate with the angle of 40 °～82 ° in stray fiber axis.More preferably 52.5 °～57.5 ° of the angles of inclined-plane 2 normals and shaft axis of optic fibre make the light propagated along shaft axis of optic fibre penetrate with the angle of 65 °～75 ° in stray fiber axis.
Fig. 2 and Fig. 3 are principle schematic of the present utility model and bevel angle design diagram, the angle δ of the normal on inclined-plane 2 and shaft axis of optic fibre is determined by following condition: when 2 outsides, inclined-plane are air, the angle of incidence γ that is transmitted all light in the laser beam of wavelength all should be greater than the angle of total reflection, i.e. Zui Xiao angle of incidence γ
m＞the angle of total reflection.This utility model when designing and calculating, notice following some: the first, same optical media is to the refractive index difference of the light of different wave length, should carry out the refractive index of transmission optical maser wavelength by silica fibre when calculating the angle of total reflection; The second, laser in optical fiber be not all be along fiber axis to propagation, but on the optical fiber wall repeatedly total reflection propagate forward, so these light and shaft axis of optic fibre have a little angle, if maximum angle is α
