[0034] See also Figures 1 to 3The utility model provides an optical fiber conduit bending and shaping device 10 for bending an optical fiber 20. The optical fiber conduit bending and shaping device 10 comprises a housing 11, an optical fiber conduit 12, an adjustment structure 13 and an optical component 14. The optical fiber conduit 12 is provided with a first through hole 121 extending along its axis (see Figure 6 ), one end of the optical fiber conduit 12 extends into the housing 11, and one end of the optical fiber 20 extends into the housing 11 and is inserted into the first through hole 121. The adjustment structure 13 includes an operating member 131 and an adjustment rope 132. The operating member 131 is arranged on the housing 11; the adjustment rope 132 is wound around the operating member 131, and both ends of the adjustment rope 132 are fixedly connected to the other end of the optical fiber conduit 12 away from the housing 11. The optical component 14 is installed at the other end of the optical fiber conduit 12 away from the housing 11, and is used to focus the laser emitted by the optical fiber 20. Among them, both ends of the adjustment rope 132 are fixed to the other end of the optical fiber conduit 12 away from the housing 11.
[0035] In this way, by setting the adjustment structure 13, the control operating member 131 can drive the adjustment rope 132 to move, the adjustment rope 132 drives the optical fiber catheter 12 to bend, and the optical fiber catheter 12 drives the optical fiber 20 to bend, thereby realizing the adjustment of the focusing position of the laser transmitted by the optical fiber 20, so that the laser acts on the tissue in a wider range to reduce the difficulty of surgical operation; by setting the optical component 14, the laser emitted by the optical fiber 20 can change its original shape after passing through the optical component 14 (originally it was in a fan-shaped divergent state, now the laser is parallel and does not diverge), so that the laser reaching the tissue surface has a focused state, so that the laser can act on the tissue more finely, reduce the heat affected area after the laser acts on the tissue, and improve the surgical accuracy.
[0036] Optionally, the adjustment rope 132 is a steel wire, which is wound around the operating member 131 , and both ends of the steel wire are fixed to the other end of the optical fiber conduit 12 away from the housing 11 .
[0037] See also Figure 3 , Figure 4 and Figure 6 In some embodiments, the optical fiber conduit 12 is further provided with two second through holes 122, and the two ends of the adjustment rope 132 respectively pass through the two second through holes 122 and are fixed to one end of the optical fiber conduit 12 away from the housing 11. The two second through holes 122 are symmetrically arranged with respect to the first through hole 121, and the axis of the second through hole 122 is parallel to the axis of the first through hole 121.
[0038] In this way, two second through holes 122 are provided to isolate the two adjustment ropes 132 and the optical fiber 20, thereby preventing the adjustment rope 132 from colliding with the optical fiber 20 when moving, thereby affecting the propagation path of the laser emitted by the optical fiber 20 and also preventing damage to the optical fiber 20; by setting the two second through holes 122 to be symmetrical about the first through hole 121, so that the adjustment rope 132 can drive the optical fiber conduit 12 to bend, it is convenient to adjust the bending angle of the optical fiber conduit 12, so that the bending direction of the optical fiber 20 is controllable, which is beneficial to improving the adjustment efficiency.
[0039] See also Figure 1 and Figure 3 In some embodiments, two adjustment structures 13 are provided, and the adjustment rope 132 of each adjustment structure 13 is wound around the operating member 131 of the same adjustment structure 13, and the two ends of the adjustment rope 132 are respectively fixed to the other end of the optical fiber conduit 12 away from the outer shell 11.
[0040] See also Figure 4 In some embodiments, the optical fiber conduit 12 is evenly spaced with four second through holes 122 around the first through hole 121, and the four ends of the two adjustment ropes 132 are respectively passed through the four second through holes 122 and fixed to the end of the optical fiber conduit 12 away from the housing 11. The axis of the second through hole 122 is parallel to the axis of the first through hole 121.
[0041] In this embodiment, two ends of the adjustment rope 132 are respectively passed through two second through holes 122 that are spaced apart from each other, so as to adjust the bending direction of the optical fiber conduit 12 according to actual use needs.
[0042] See also Figure 3 In some embodiments, the operating member 131 includes an operating knob 1311 and a fixing portion 1312 that are fixedly connected, the operating knob 1311 is located outside the housing 11, and the fixing portion 1312 is located inside the housing 11, and is used to wind the adjustment rope 132 of the same adjustment structure 13. The operating knob 1311 can rotate.
[0043] In this way, by rotating the operating knob 1311 , the fixing portion 1312 will also rotate, thereby driving the adjustment rope 132 to move, and the adjustment rope 132 drives the optical fiber conduit 12 to bend.
[0044] It is understandable that the operating member 131 can also be configured to move along the axis of the housing 11 according to actual use needs, thereby driving the adjustment rope 132 to move. In other words, the operating member 131 can drive the adjustment rope 132 to move, so that the adjustment rope 132 can drive the optical fiber conduit 12 to bend.
[0045] See also Figure 3In some embodiments, an annular groove 1313 is provided on the outer periphery of the fixing portion 1312 , and the adjustment rope 132 of the same adjustment structure 13 is wound around the annular groove 1313 .
[0046] In this way, the annular groove 1313 is provided to facilitate installation and positioning of the adjustment rope 132 .
[0047] See also Figure 3 In some embodiments, the optical fiber conduit bending and shaping device 10 further includes a mounting structure 15, the mounting structure 15 is mounted on the housing 11, the operating member 131 is rotatably mounted on the mounting structure 15, the operating knob 1311 is located outside the mounting structure 15, and the fixing portion 1312 is located in the mounting cavity 151 of the mounting structure 15. The two operating members 131 are installed on the mounting structure 15 at intervals.
[0048] In this way, the mounting structure 15 is provided to mount the operating member 131 , and at the same time, the mounting structure 15 can also limit the position of the adjustment rope 132 .
[0049] It is understandable that the mounting structure 15 and the housing 11 can be configured as two separate structures, or can be an integrally formed structure, as long as it can meet actual usage requirements.
[0050] See also Figure 1 and Figure 4 In some embodiments, the optical fiber conduit bending and shaping device 10 further includes a protection tube 16, one end of which extends into the housing 11, the optical fiber conduit 12 is passed through the protection tube 16, and both ends of the optical fiber conduit 12 extend out of the protection tube 16. The hardness of the protection tube 16 is relatively large, greater than that of the optical fiber conduit 12.
[0051] By providing the protection tube 16 in this manner, the optical fiber guide tube 12 can be protected.
[0052] See also Figure 5 In some embodiments, the optical assembly 14 includes a sleeve 141, a collimator lens 142, a focusing lens 143, and a protective lens (not shown in the figure). The sleeve 141 is installed at the other end of the optical fiber conduit 12 away from the housing 11. The collimator lens 142, the focusing lens 143, and the protective lens are sequentially installed in the sleeve 141 along the direction from the housing 11 to the optical assembly 14. Among them, the collimator lens 142 collimates the laser emitted by the optical fiber 20, the focusing lens 143 focuses the laser emitted by the optical fiber 20, and the protective lens can protect the collimator lens 142 and the focusing lens 143.
[0053] It should be noted that the optical component 14 may also be composed of other optical lenses or optical structures, and the setting positions of different components may be replaced according to actual use needs, and no further restrictions are made here.
[0054] See also Figure 1 and Figure 3 In some embodiments, the housing 11 includes a first guide member 111, a shell 112, and a second guide member 113 connected in sequence, the first guide member 111 is used to guide the installation of the optical fiber 20, the shell 112 is used to install the adjustment structure 13, and the second guide member 113 is used to guide the installation of the optical fiber conduit 12.
[0055] It is understandable that the optical fiber 20 and the optical fiber conduit 12 are relatively long, and the first guide member 111 and the second guide member 113 can play a guiding role during installation, and can also play a supporting role.
[0056] The optical fiber catheter bending and shaping device 10 can be used in an endoscope to adjust the propagation path of the thulium laser generated by the optical fiber in the endoscope, so that the thulium laser that was originally in a fan-shaped divergent state can be parallel, and the thulium laser that reaches the tissue surface can be in a focused state, thereby reducing the heat affected area after the laser acts on the tissue and improving the surgical accuracy.
[0057] Of course, the optical fiber catheter bending and shaping device 10 can also be applied to other devices according to actual use needs.
