[0035] See also Figures 1 to 3 The utility model provides an optical fiber installation device 10, comprising an installation seat 11, a fixing member 12, a reset member 13, a limit member 14 and an optical fiber installation tube 15. The installation seat 11 is provided with an installation cavity 111 and a first through hole 112 connected to the installation cavity 111, and the installation cavity 111 is extended along a first direction X. One end of the fixing member 12 extends into the installation cavity 111; the reset member 13 is sleeved on the fixing member 12, and when the other end of the fixing member 12 is away from the installation cavity 111, the reset member 13 is in contact with the limit surface 125 (see Figure 2 ) abuts. The limiting member 14 is sleeved on the fixing member 12 and connected to the mounting seat 11. The limiting member 14 and the limiting surface 125 are used together to limit the reset member 13, so that the reset member 13 has a movement tendency to push the fixing member 12 to extend into the mounting cavity 111. The optical fiber installation tube 15 extends into the first through hole 112 and is detachably connected to the fixing member 12; the optical fiber (not shown in the figure) is inserted into the optical fiber installation tube 15.

[0036] See also Figure 3, wherein the reset member 13 and the limiting member 14 are sequentially arranged along the first direction X, and an end surface of the limiting member 14 facing the reset member 13 can selectively abut against the reset member 13. Optionally, the reset member 13 is a spring.

[0037] In this way, by setting the optical fiber mounting tube 15 and the fixing member 12 as a detachable connection, the optical fiber mounting tube 15 can be replaced to adapt to different types of optical fibers, thereby avoiding frequent replacement of laser cystoscopes and facilitating operation; by setting a limit surface 125 on the fixing member 12 and a limit member 14 to limit the installation position of the reset member 13 on the fixing member 12, when it is necessary to replace the optical fiber mounting tube 15, the fixing member 12 is kept pulled outward and the optical fiber mounting tube 15 is taken out, at which time the reset member 13 is compressed, and then the optical fiber mounting tube 15 is extended into the first through hole 112, and then the fixing member 12 is released, at which time the reset member 13 pushes the fixing member 12 to move so that the fixing member 12 is connected to the optical fiber mounting tube 15.

[0038] See also Figure 2 In some embodiments, the first through hole 112 penetrates the mounting seat 11 along the second direction Y, and the optical fiber mounting tube 15 extends along the second direction Y. The first direction X and the second direction Y are perpendicular to each other.

[0039] See also Figure 2 and Figure 3 In some embodiments, the end of the fixing member 12 extending into the installation cavity 111 is provided with a clamping portion 121, and the end of the optical fiber installation tube 15 extending into the first through hole 112 is provided with a clamping groove 151, and the clamping portion 121 is clamped with the clamping groove 151. The clamping groove 151 is connected with the channel of the optical fiber installation tube 15 for installing the optical fiber.

[0040] Furthermore, the end surface of the clamping portion 121 facing the clamping slot 151 is adapted to the shape of the outer contour of the clamping slot 151 and the optical fiber installation tube 15 , and part of the clamping slot 151 extends into the clamping slot 151 to install and limit the optical fiber installation tube 15 .

[0041] In this way, the optical fiber installation tube 15 is snap-connected with the fixing member 12 to facilitate the disassembly and assembly of the optical fiber installation tube 15. When a different type of optical fiber needs to be replaced, the corresponding optical fiber installation tube 15 is replaced first, and then the required type of optical fiber is installed.

When installing the optical fiber installation tube 15, the first mark is aligned with the second mark so that the card slot 151 of the optical fiber installation tube 15 and the card connection portion 121 of the fixing member 12 can be exactly aligned to facilitate card connection.

[0043] See also Figure 2 and Figure 3 In some embodiments, the fixing member 12 includes a first section 122 and a second section 123 connected in sequence along the first direction X, the reset member 13 and the limit member 14 are both sleeved on the second section 123, and the clamping portion 121 is provided at one end of the first section 122 away from the second section 123. The diameter of the first section 122 is greater than the diameter of the second section 123, and the end surface of the first section 122 facing the second section 123 forms a limit surface 125.

[0044] In this way, by setting the fixing member 12 as stepped sections with different diameters, a step surface is formed between the first section 122 and the second section 123. The step surface is the above-mentioned limiting surface 125, which is used to limit the reset member 13 to prevent the reset member 13 from moving to the first section 122 and causing interference.

[0045] See also Figure 2 In some embodiments, the cavity wall of the installation cavity 111 is provided with a groove 114 extending along the first direction X, and the first section 122 is radially penetrated with a second through hole 1221.

[0046] Furthermore, in some embodiments, two grooves 114 are provided at intervals, and opposite ends of the anti-rotation component 16 are respectively disposed in the two grooves 114 .

[0047] In this way, an anti-rotation component 16 is provided, and the end of the anti-rotation component 16 is provided in the groove 114 to limit the rotation of the anti-rotation component 16, thereby limiting the rotation of the fixing component 12 in the installation cavity 111, thereby preventing the fixing component 12 from rotating and causing the card slot 151 on the optical fiber installation tube 15 to be unable to be aligned with the card connection portion 121 on the fixing component 12; providing two grooves 114 can enhance the anti-rotation effect.

[0048] See also Figure 2 and Figure 3 In some embodiments, the fixing member 12 further includes a third section 124 connected to an end of the second section 123 away from the first section 122 , and the third section 124 is at least partially located outside the installation cavity 111 .

[0049] See also Figure 2 and see Figure 5 Further, in some embodiments, the optical fiber installation device 10 further includes an operating member 17, and the operating member 17 is installed on the third section 124. Optionally, the third section 124 is threadedly connected to the operating member 17, the outer circumference of the third section 124 is provided with an external thread, and the end of the operating member 17 facing the third section 124 is provided with an internal thread.

[0050] In this way, by providing the third section 124 and the operating member 17 that are threadedly connected, the operator can move the fixing member 12 by pushing and pulling the operating member 17, thereby realizing the disassembly and assembly of the optical fiber installation tube 15, and the operation is simple and convenient.

[0051] It can be understood that the operating member 17 is provided for the convenience of the operator to hold it, and the operator can also directly hold the third section 124 for operation, or make the second section 123 partially extend out of the installation cavity 111, and hold the second section 123 to move the fixing member 12, which can meet the actual use needs and realize the disassembly and assembly of the optical fiber installation tube 15.

[0052] In some embodiments, the stopper 14 is threadedly connected to the inner wall of the installation cavity 111. The end of the installation cavity 111 is provided with an internal thread, and at least part of the outer periphery of the stopper 14 is provided with an external thread to achieve detachable installation of the first stopper, so as to facilitate installation and removal of the fixing member 12 and the reset member 13 as needed.

[0053] See also Figure 4 The utility model also provides a laser cystoscope, comprising an optical fiber and the optical fiber installation device 10 in the above embodiment, wherein the optical fiber is inserted into an optical fiber installation tube 15 of the optical fiber installation device 10 .

In other embodiments, the connector is provided with an opening, and the connector can undergo a restorable deformation under the action of an external force, and the optical fiber installation device 10 is pressed into the opening of the connector by an external force, and the outer diameter of the optical fiber installation device 10 is larger than the size of the opening.

[0055] See also Figure 4 In some embodiments, the laser cystoscope further includes an optical fiber locking member 30, which is used to lock or unlock the optical fiber. The optical fiber locking member 30 is pressed to unlock the optical fiber, and the optical fiber can be locked by releasing the optical fiber locking member 30. In this embodiment, the locking and unlocking principles of the optical fiber locking member 30 are relatively conventional, and its specific structure and principle are not described here. Any locking member that can achieve its function can be used.

[0056] It is understandable that the laser cystoscope also includes other components such as an imaging system and an electron microscope sheath. These structures are widely available and will not be described in detail here.

[0057] The installation process of the laser cystoscope is as follows:

[0058] First, the anti-rotation member 16 is inserted into the second through hole 1221, and the opposite ends of the anti-rotation member 16 are respectively arranged in the two grooves 114; then the fixing member 12 is extended into the installation cavity 111, and the reset member 13 and the limit member 14 are sequentially sleeved on the second section 123 of the fixing member 12, and the limit member 14 is tightened; then the operating member 17 is installed on the third section 124.
