Sealing and fixed communication, the front end of the optical fiber is inserted into the front elastic micro-duct through the insertion port of the three-way, and goes deep into the front end of the front elastic micro-duct, the technical means that the optical fiber is sealed and fixedly connected with the insertion port of the three-way, so, like this The Schlemm elastic microcatheter is not only easy to manufacture, but also increases the connection strength between the optical fiber and the elastic microcatheter, improving the sealing performance. the

作为本实施方式的一种改进，如图2所示，所述三通6呈倒“T”字型；所述三通6的出口与所述三通6的插入口位于同一条轴线上，所述三通6的入口与所述三通6的插入口之间的夹角小于90°。 As an improvement of this embodiment, as shown in Figure 2, thetee 6 is in an inverted "T "shape; the outlet of thetee 6 is located on the same axis as the insertion port of thetee 6, The angle between the inlet of thetee 6 and the insertion port of thetee 6 is less than 90°.

本实施方式由于采用了三通呈倒“T”字型（也就是将“T”顺时针旋转180°）；三通的出口与三通的插入口位于同一条轴线上的技术手段，所以，在制造施莱姆氏管（ Schlemm ）弹性微导管的过程中，可以很容易地将光导纤维插入到前弹性微导管的前端，因而，这样的施莱姆氏管（ Schlemm ）弹性微导管制造更容易。又由于采用了三通的入口与三通的插入口之间的夹角小于90°的技术手段，所以，在注射粘弹剂的过程中，可有效地减小粘弹剂在施莱姆氏管（ Schlemm ）弹性微导管中的阻力，降低了医务人员的劳动强度。 This embodiment adopts the technical means that the tee is in an inverted "T " shape (that is, the "T " is rotated 180° clockwise); the outlet of the tee and the insertion port of the tee are located on the same axis, so, In the process of manufacturing Schlemm's canal (Schlemm) elastic microcatheter, the optical fiber can be easily inserted into the front end of the front elastic microcatheter, therefore, the manufacture of such Schlemm's canal (Schlemm) elastic microcatheter easy. And because the angle between the entrance of the tee and the insertion port of the tee is less than 90°, so, in the process of injecting the viscoelastic, the viscoelasticity in Schlemm's can be effectively reduced. Tube (Schlemm) resistance in the elastic microcatheter reduces the labor intensity of the medical staff.

作为本实施方式进一步的改进，如图2所示，所述三通6的入口与所述三通6的插入口之间的夹角为45°。当然，所述三通6的入口与所述三通6的插入口之间的夹角也可以为15°、20°、25°、30°、35°或40°。 As a further improvement of this embodiment, as shown in FIG. 2 , the angle between the inlet of thetee 6 and the insertion port of thetee 6 is 45°. Of course, the angle between the inlet of thetee 6 and the insertion port of thetee 6 may also be 15°, 20°, 25°, 30°, 35° or 40°. the

本实施方式由于采用了三通的入口与三通的插入口之间的夹角为15°、20°、25°、30°、35°、40°或45°等多个角度的技术手段，所以，可制造出不同品种的施莱姆氏管（ Schlemm ）弹性微导管供用户有选择地使用。 In this embodiment, because the angle between the entrance of the tee and the insertion port of the tee is 15°, 20°, 25°, 30°, 35°, 40° or 45° and other technical means, Therefore, different varieties of Schlemm elastic microcatheters can be manufactured for users to selectively use. the

作为本实施方式上述二个实施例的进一步的改进，如图1和图2所示，所述弹性微导管1的前部11，从前到后依次为工作导管111、过渡导管112和辅助导管113；所述辅助导管113的外径大于所述工作导管111的外径；所述辅助导管113的内径大于或等于所述工作导管111的内径。 As a further improvement of the above two examples of this embodiment, as shown in Figure 1 and Figure 2, thefront part 11 of the elastic microcatheter 1, from front to back, is a workingcatheter 111, atransition catheter 112 and anauxiliary catheter 113. ; The outer diameter of theauxiliary conduit 113 is greater than the outer diameter of the workingconduit 111 ; The inner diameter of theauxiliary conduit 113 is greater than or equal to the inner diameter of the workingconduit 111 . the

本实施方式由于采用了辅助导管外径大于工作导管外径的技术手段，所以，医务人员可握持着较粗的辅助导管轻易地将较细的工作导管插入施莱姆氏管（ Schlemm ）中，提高了施莱姆氏管（ Schlemm ）弹性微导管的易用性。当采用辅助导管的内径大于工作导管的内径时，在注射粘弹剂的过程中，可进一步地减小粘弹剂在施莱姆氏管（ Schlemm ）弹性微导管中的阻力，进一步降低了医务人员的劳动强度。当采用辅助导管的内径等于工作导管的内径时，辅助导管的管壁增厚，因而刚度增大，进一步提高了施莱姆氏管（ Schlemm ）弹性微导管的易用性。 This embodiment adopts the technical means that the outer diameter of the auxiliary catheter is larger than the outer diameter of the working catheter, so the medical staff can easily insert the thinner working catheter into the Schlemm's canal by holding the thicker auxiliary catheter , to improve the ease of use of the Schlemm canal (Schlemm) elastic microcatheter. When the inner diameter of the auxiliary catheter is larger than the inner diameter of the working catheter, the resistance of the viscoelastic agent in the Schlemm elastic microcatheter can be further reduced during the injection of the viscoelastic agent, further reducing medical costs. Labor intensity of personnel. When the inner diameter of the auxiliary catheter is equal to the inner diameter of the working catheter, the wall of the auxiliary catheter is thickened, so the stiffness is increased, which further improves the ease of use of the elastic microcatheter of Schlemm's canal (Schlemm). the

作为本实施方式再进一步的改进，所述工作导管111的长度为25~40cm，外径为200μm，内径为100μm；所述过渡导管112的长度为5~10cm，所述辅助导管113的长度为50cm，外径为1mm，内径为500μm；所述光导纤维2的直径为50μm。 As a further improvement of this embodiment, the length of the workingconduit 111 is 25-40 cm, the outer diameter is 200 μm, and the inner diameter is 100 μm; the length of thetransition conduit 112 is 5-10 cm, and the length of theauxiliary conduit 113 is 50 cm, the outer diameter is 1 mm, and the inner diameter is 500 μm; the diameter of theoptical fiber 2 is 50 μm. the

本实施方式由于采用了工作导管的长度为25~40cm，外径为200μm，内径为100μm；过渡导管的长度为5~10cm，辅助导管的长度为50cm，外径为1mm，内径为500μm；光导纤维的直径为50μm的技术手段，所以，这样的施莱姆氏管（ Schlemm ）弹性微导管可适用于大多数的患者，有利于施莱姆氏管（ Schlemm ）弹性微导管的推广应用。 In this embodiment, the length of the working catheter is 25-40 cm, the outer diameter is 200 μm, and the inner diameter is 100 μm; the length of the transition catheter is 5-10 cm, the length of the auxiliary catheter is 50 cm, the outer diameter is 1 mm, and the inner diameter is 500 μm; The diameter of the fiber is 50 μm, so the Schlemm canal (Schlemm) elastic microcatheter can be applied to most patients, which is conducive to the popularization and application of the Schlemm canal (Schlemm) elastic microcatheter. the

作为本实施方式更进一步的改进，如图1和图2所示，所述工作导管111的前端头14为膨大头。膨大头呈球壳状或椭圆球壳，其上有粘弹剂出口。当然，也可以是所述工作导管111前端部的侧壁设有沿着周向延伸的凹槽。 As a further improvement of this embodiment, as shown in FIG. 1 and FIG. 2 , thefront end 14 of the workingcatheter 111 is an enlarged head. The enlarged head is in the shape of a spherical shell or an elliptical spherical shell with a viscoelastic outlet on it. Of course, it is also possible that the side wall of the front end of the workingcatheter 111 is provided with a groove extending along the circumferential direction. the

本实施方式由于采用了工作导管前端部的侧壁设有沿着周向延伸的凹槽，或者工作导管的前端头为膨大头的技术手段，所以，这样的施莱姆氏管（ Schlemm ）弹性微导管不但可以用于向施莱姆氏管（ Schlemm ）中注射粘弹剂，而且还可以通过医用缝合线将施莱姆氏管（ Schlemm ）扩张支架植入施莱姆氏管（ Schlemm ）中。 This embodiment adopts the technical means that the side wall of the front end of the working catheter is provided with a groove extending along the circumferential direction, or the front end of the working catheter is an enlarged head. Therefore, such Schlemm canal (Schlemm) is elastic Microcatheter can be used not only to inject viscoelastic into Schlemm, but also to implant Schlemm expansion stent into Schlemm through medical suture . the
