Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to an optical fiber loader. Background Technology

[0002] The incidence of urinary tract stones and digestive system stones is on the rise, posing a serious threat to human health. In recent years, with the development of non-invasive treatment technologies, endoscopic devices combined with laser lithotripsy have become an important means of stone treatment. During laser lithotripsy, an optical fiber is loaded and fixed using a fiber optic loader, allowing the fiber tip to pass through the endoscope and reach the camera at the end of the endoscope. The operator can judge the distance between the fiber tip and the stone by viewing the image captured by the camera on the display screen. The energy emitted by the laser acts on the stone through the fiber tip, thus breaking it up. However, with traditional fiber optic loaders, bodily fluids often leak through the loader, affecting its sealing performance. Summary of the Invention

[0003] One of the technical problems addressed by this application is how to improve the sealing performance of fiber optic loaders.

[0004] An optical fiber loader, comprising:

[0005] First installation organization;

[0006] The second mounting mechanism is detachably connected to the first mounting mechanism, and the second mounting mechanism has a through hole for inserting optical fibers.

[0007] A guiding mechanism, connected to the second installation mechanism and used for threading optical fibers; and

[0008] A sealing mechanism abuts between the guiding mechanism and the first mounting mechanism, the sealing mechanism having a sealing hole that communicates with the through hole and is used for inserting an optical fiber;

[0009] When the first mounting mechanism comes into contact with the sealing mechanism, the sealing mechanism deforms to reduce the diameter of the sealing hole and make it interference fit with the optical fiber.

[0010] In one embodiment, the guide seat has a guide hole, the sealing mechanism includes a sealing unit and a limiting unit, the sealing unit protrudes from the limiting unit, the cross-section of the limiting unit is larger than the cross-section of the sealing unit, the sealing hole is formed in the sealing unit, the sealing unit cooperates with the guide hole, and the limiting unit is located outside the guide hole and abuts between the guide mechanism and the first mounting mechanism.

[0011] In one embodiment, the sealing unit includes a cylindrical segment and a conical segment, the cylindrical segment being connected between the conical segment and the limiting unit, the guide hole including a conical hole and a cylindrical hole, the cylindrical segment engaging with the cylindrical hole, the conical segment engaging with the conical hole, the sealing hole being formed in the conical segment, in a direction pointing from the cylindrical hole to the conical hole, the cross-sectional dimensions of the cylindrical hole and the cylindrical segment being constant, and the cross-sectional dimensions of the conical segment and the conical hole being reduced.

[0012] In one embodiment, the tapered hole includes a first tapered segment and a second tapered segment arranged coaxially, the first tapered segment connecting the second tapered segment and the cylindrical segment, and the tapered angle of the first tapered segment being greater than the tapered angle of the second tapered segment.

[0013] In one embodiment, the sealing mechanism includes a first seal and a second seal that are detachably connected, the first seal being more flexible than the second seal, the sealing hole being formed in the first seal, and the first mounting mechanism abutting against the second seal.

[0014] In one embodiment, the first seal includes an insertion portion and an abutment portion, the insertion portion protruding from one end of the abutment portion, the sealing hole being located in the abutment portion, the second seal having an insertion hole that mates with the insertion portion, and the abutment portion being located outside the insertion hole and abutting between the second seal and the guide mechanism.

[0015] In one embodiment, the guiding mechanism includes a guide seat and a protruding ring, the protruding ring being disposed on the outer peripheral surface of the guide seat, the guide seat being inserted into the second mounting mechanism, and the protruding ring being located outside the second mounting mechanism and abutting against the second mounting mechanism.

[0016] In one embodiment, the first mounting mechanism includes a first mounting member and a force-applying member connected to each other. The first mounting member is rotatable relative to the second mounting mechanism and is detachably connected to the second mounting mechanism. The force-applying member has a force-applying curved surface that abuts against the sealing mechanism. From one end of the force-applying curved surface near the first mounting member to the other end away from the first mounting member, along the axial direction of the guide mechanism, the distance from the force-applying curved surface to the sealing hole first decreases and then increases.

[0017] In one embodiment, the first mounting mechanism further includes a switch and an elastic element. The switch includes a snap-fit ​​portion, a connecting portion, and a switching portion. The connecting portion is connected between the snap-fit ​​portion and the switching portion and is rotatably connected to the first mounting member. The elastic element abuts between the first mounting member and the switching portion. The snap-fit ​​portion is snap-fit ​​connected to the second mounting mechanism.

[0018] In one embodiment, at least one of the following schemes is also included:

[0019] The second mounting mechanism includes a second mounting member and a protruding post. The protruding post protrudes from two opposite sides of the second mounting member. A slot is provided on the first mounting member, which passes through the end face of the first mounting member and rotatably engages with the protruding post.

[0020] When the first mounting mechanism is connected to the second mounting mechanism, the position where the distance from the force-applying curved surface to the sealing hole is the smallest is spaced apart from the sealing mechanism.

[0021] One technical effect of one embodiment of this application is that when the optical fiber is inserted into the sealing hole, and the first mounting mechanism abuts against the sealing mechanism, the sealing mechanism undergoes elastic deformation, causing the diameter of the sealing hole to decrease. This results in an interference fit between the sealing hole and the optical fiber, thereby sealing the optical fiber and effectively preventing bodily fluids from leaking out of the optical fiber loader, thus improving the sealing performance of the optical fiber loader. Simultaneously, when the first mounting mechanism stops applying the abutting force to the sealing mechanism, the elastic deformation of the sealing mechanism disappears, and the diameter of the sealing hole increases, resulting in a clearance fit between the sealing hole and the optical fiber. During the installation of the optical fiber, this reduces the resistance between the optical fiber and the sealing hole, preventing the optical fiber from breaking, thereby improving the installation efficiency and reliability of the optical fiber.

[0045] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0046] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0047] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0048] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0049] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0050] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0051] See Figure 1 , Figure 2 and Figure 3 An embodiment of this application provides an optical fiber loader 10 for loading an optical fiber 20. The optical fiber loader 10 includes a first mounting mechanism 100, a second mounting mechanism 200, a first fixing mechanism 300, a second fixing mechanism 400, a guiding mechanism 500, and a sealing mechanism 600. The first mounting mechanism 100 is connected to the second mounting mechanism 200. The first fixing mechanism 300 is disposed on the first mounting mechanism 100. The second fixing mechanism 400 and the guiding mechanism 500 are disposed on the second mounting mechanism 200. The sealing mechanism 600 is disposed on the guiding mechanism 500. A through hole 211 is provided on the second mounting mechanism 200, through which the optical fiber 20 passes. At the same time, the optical fiber 20 also passes through the guiding mechanism 500 and the sealing mechanism 600. The first fixing mechanism 300 and the second fixing mechanism 400 can fix the optical fiber 20, preventing the optical fiber 20 from sliding relative to the through hole 211.

[0052] See Figure 3 , Figure 4 , Figure 5 and Figure 6 In some embodiments, the first mounting mechanism 100 and the second mounting mechanism 200 are detachably connected, for example, by means of a snap-fit ​​connection. The first mounting mechanism 100 may include a first mounting member 110, a switching member 120, an elastic member 130, and a force-applying member 140. The first mounting member 110 has a first mounting hole 111 for receiving the first fixing mechanism 300. The first mounting member 110 includes two spaced-apart lugs 112, each with a slot 1121. The lugs 112 can clamp the second mounting mechanism 200. The slots 1121 are circumferentially open, allowing the second mounting mechanism 200 to enter the slot 1121 through its opening. The slots 1121 rotatably engage with the second mounting mechanism 200, allowing the first mounting mechanism 100 to rotate relative to the second mounting mechanism 200. In other embodiments, the card slot 1121 may also be provided on the second mounting mechanism 200.

[0053] See Figure 5 , Figure 7 , Figure 8 and Figure 9 In some embodiments, the switch 120 includes a latching portion 121, a connecting portion 122, and a switching portion 123, with the connecting portion 122 connected between the latching portion 121 and the switching portion 123. The connecting portion 122 is rotatably connected to the first mounting member 110, for example, the connecting portion 122 can be rotatably connected to the first mounting member 110 via a pin. The elastic member 130 can be a spring or the like, and the elastic member 130 abuts against the first mounting member 110 and the switching portion 123. The latching portion 121 is latched to the second mounting mechanism 200. The latching part 121 has a first plane 1211, a first inclined surface 1212, and a limiting surface 1213. The first plane 1211 and the first inclined surface 1212 are set at an acute angle. When the latching part 121 is latched and connected to the second mounting mechanism 200, the first plane 1211 is parallel to the center line of the through hole 211, and the first inclined surface 1212 is closer to the through hole 211 than the first plane 1211. This can be understood as the first inclined surface 1212 being located below the first plane 1211, so that the first inclined surface 1212 faces the through hole 211, and the first plane 1211 faces away from the through hole 211. The distance from the first inclined surface 1212 to the first fixing mechanism 300 decreases from the end of the first inclined surface 1212 closest to the through hole 211 to the end furthest from the through hole 211. The limiting surface 1213 is connected to the end of the first plane 1211 away from the first inclined surface 1212. The limiting surface 1213 can extend in the vertical direction, so that the limiting surface 1213 is further away from the through hole 211 relative to the first plane 1211, that is, the limiting surface 1213 is located above the first plane 1211. The limiting surface 1213 can abut against the second mounting member 210 in the horizontal direction.

[0054] See Figure 5 , Figure 7 , Figure 8 and Figure 9 In some embodiments, the first mounting member 110 further includes a force-applying member 140, which protrudes from the first mounting member 110. The force-applying member 140 has a force-applying curved surface 141. After the first mounting mechanism 100 and the second mounting mechanism 200 are connected, the distance from the end of the force-applying curved surface 141 near the first mounting member 110 to the end away from the first mounting member 110 decreases and then increases in the horizontal direction to the guide seat 510, thus making the force-applying curved surface 141 approximately arc-shaped. The force-applying curved surface 141 is used to generate a resisting force on the sealing mechanism 600. This horizontal direction can be understood as the axial direction of the guide mechanism 500.

[0055] See Figure 4 , Figure 5 and Figure 10 In some embodiments, the second mounting mechanism 200 includes a second mounting member 210 and two protrusions 220. The protrusions 220 are two in number and extend horizontally, protruding from two opposite sides of the second mounting member 210. The protrusions 220 rotatably engage with slots 1121 on the first mounting member 110, allowing the first mounting mechanism 100 to rotate relative to the second mounting mechanism 200 around the protrusions 220. The second mounting member 210 has a second mounting hole 212, and a through hole 211 is formed on the second mounting member 210, such that the through hole 211 and the second mounting hole 212 communicate with each other. The second mounting hole 212 is used to accommodate the second fixing mechanism 400. The second mounting member 210 has a second plane 213 and a second inclined plane 214, which are set at an acute angle. When the snap-fit ​​part 121 is snapped into contact with the second mounting member 210, the second plane 213 is parallel to the center line of the through hole 211, and the second plane 213 can be parallel to the first plane 1211. The first inclined plane 1212 and the second inclined plane 214 can also be parallel to each other. The second inclined plane 214 is further away from the through hole 211 than the second plane 213. In simpler terms, the second inclined plane 214 is located above the second plane 213, so that the second inclined plane 214 faces away from the through hole 211, while the second plane 213 faces the through hole 211. The distance from the second inclined plane 214 to the first fixing mechanism 300 decreases from the end of the second inclined plane 214 closest to the through hole 211 to the end furthest from the through hole 211.

[0056] See Figure 4 , Figure 5 , Figure 10 and Figure 12During the assembly of the first mounting mechanism 100 and the second mounting mechanism 200, the first mounting member 110 can first be moved downward in the vertical direction, so that the slot 1121 and the protrusion 220 cooperate with each other. Then, the first mounting member 110 rotates around the protrusion 220 relative to the second mounting member 210, so that the switch member 120 moves downward and gradually approaches the second mounting member 210, and the force-applying member 140 gradually extends into the second mounting hole 212. When the first inclined surface 1212 and the second inclined surface 214 abut against each other, the second inclined surface 214 will generate a horizontal component force on the latching part 121 through the first inclined surface 1212. This component force will push the latching part 121 away from the first mounting member 110 and rotate, so that the switch part 123 rotates closer to the first mounting member 110, and the elastic member 130 compresses and stores energy. As the switch 120 continues to move downward toward the second mounting member 210, when the first inclined surface 1212 and the second inclined surface 214 disengage, the latching part 121 will experience a "stepping into the void" effect. The elastic member 130 will release energy and push the switch part 123 away from the first mounting member 110, causing the first plane 1211 and the second plane 213 to abut against each other in the vertical direction, preventing the first mounting mechanism 100 from disengaging from the second mounting mechanism 200 in the vertical direction. At the same time, the second mounting member 210 abuts against the limiting surface 1213, thus preventing the first mounting member 110 from continuing to rotate forward around the protrusion 220. Ultimately, the first mounting mechanism 100 can achieve a latching connection with the second mounting mechanism 200 through the switch 120.

[0057] When it is necessary to disconnect the connection between the first mounting mechanism 100 and the second mounting mechanism 200, a pressing force can first be applied to the switching part 123 of the switching member 120 toward the first mounting member 110. At this time, the elastic member 130 is compressed and stores energy, and the latching part 121 rotates away from the second plane 213. When the first plane 1211 and the second plane 213 disengage from each other, the interference of the second mounting member 210 on the latching part 121 and the first mounting member 110 can be eliminated, thereby causing the entire first mounting member 110 to move upward away from the second mounting mechanism 200. After the first mounting member 110 moves away from the second mounting mechanism 200 by a set angle, the force-applying member 140 will disengage from the second mounting hole 212 and be located outside the second mounting hole 212. At this time, an upward pulling force can be applied to the first mounting member 110, causing the slot 1121 to disengage from the engagement with the protrusion 220, thereby realizing the unloading of the first mounting mechanism 100 relative to the second mounting mechanism 200.

[0058] It is understood that by applying force to the force-applying curved surface 141 on the force-applying member 140, on the one hand, the force-applying curved surface 141 can apply a resisting force to the sealing mechanism 600, and on the other hand, during the rotation of the first mounting mechanism 100 around the protrusion 220, interference between the force-applying member 140 and the second mounting member 210 can be effectively avoided, thereby realizing the smooth loading and unloading of the first mounting mechanism 100 relative to the second mounting mechanism 200.

[0059] See Figure 3 , Figure 7 and Figure 8 In some embodiments, the first fixing mechanism 300 includes a first elastic body 310, which is connected to the first mounting member 110. For example, the first elastic body 310 can be fixedly connected to the first mounting member 110. The first elastic body 310 is made of rubber material, thus giving it a certain degree of elasticity. The first elastic body 310 can be cylindrical, and its outer peripheral surface is used to abut against the optical fiber 20. The first elastic body 310 is at least partially housed in the first mounting hole 111, so it can make full use of the housing space formed by the first mounting hole 111, thereby facilitating the compact design of the optical fiber loader 10.

[0060] See Figure 3 , Figure 10 and Figure 11 In some embodiments, the second fixing mechanism 400 includes a second elastic body 410, which is connected to the second mounting member 210. For example, the second elastic body 410 can be fixedly connected to the second mounting member 210. The second elastic body 410 is made of rubber material, thus giving it a certain degree of elasticity. The second elastic body 410 can be cylindrical, and its outer peripheral surface is used to abut against the optical fiber 20. The second elastic body 410 is at least partially housed in the second mounting hole 212, so it can make full use of the housing space formed by the second mounting hole 212, thereby facilitating the compact design of the optical fiber loader 10. The central axes of the first elastic body 310 and the second elastic body 410 can be parallel to each other, and the plane containing the two central axes can be perpendicular to the extension direction of the through hole 211 and the optical fiber 20.

[0061] In other embodiments, the first elastic body 310 may also be prismatic. The second elastic body 410 may also be prismatic.

[0062] See Figure 5When the first mounting mechanism 100 is snapped together with the second mounting mechanism 200 via the switch 120, the optical fiber 20 is abutted between the first elastic body 310 and the second elastic body 410. This means the first and second elastic bodies 310 and 410 effectively clamp the optical fiber 20, and a reasonable static friction exists between them and the optical fiber 20. This prevents the optical fiber 20 from sliding relative to the first elastic body 310, the second elastic body 410, and the through hole 211, thus effectively fixing the optical fiber 20. This ensures that the extension length of the optical fiber 20 relative to the optical fiber loader 10 is appropriate, maintaining a reasonable distance between the head of the optical fiber 20 and the stone. Therefore, when the first mounting mechanism 100 is snapped together with the second mounting mechanism 200 via the switch 120, by reasonably controlling the distance between the central axes of the first elastic body 310 and the second elastic body 410 during the design process, the clamping force of the first and second elastic bodies 310 on the optical fiber 20 can be determined, effectively preventing the optical fiber 20 from sliding relative to the through hole 211. Meanwhile, given that the first elastic body 310 and the second elastic body 410 have good elasticity, damage to the optical fiber 20 can be effectively avoided by the first elastic body 310 and the second elastic body 410 during the clamping process, thereby improving the stability and reliability of the optical fiber loader 10 in fixing the optical fiber 20.

[0063] Meanwhile, given the detachable connection between the first mounting mechanism 100 and the second mounting mechanism 200 via a snap-fit ​​connection, it can be understood that the first mounting mechanism 100 and the second mounting mechanism 200 are modular designs. During the installation of the optical fiber 20 by passing it through the through hole 211, the first mounting mechanism 100 is not connected to the second mounting mechanism 200. This eliminates interference from the first mounting mechanism 100, thereby increasing the installation space for the optical fiber 20 and preventing damage to the optical fiber 20 during installation, thus improving the efficiency and reliability of the optical fiber 20 installation. After the optical fiber 20 is passed through the through hole 211, the first mounting mechanism 100 and the second mounting mechanism 200 are snap-fit ​​connected.

[0064] See Figure 1 and Figure 5In some embodiments, the first elastic body 310 is rotatably connected to the first mounting member 110, and the second elastic body 410 is rotatably connected to the second mounting member 210. The axes around which the first elastic body 310 and the second elastic body 410 rotate are parallel to each other, and the plane containing the two axes is perpendicular to the center line of the through hole 211. When a rotational torque is applied to either the first elastic body 310 or the second elastic body 410, under the action of friction between the first elastic body 310 and the second elastic body 410, the first elastic body 310 and the second elastic body 410 rotate relative to each other, thereby causing the first elastic body 310 and the second elastic body 410 to drive the optical fiber 20 to move relative to the through hole 211. It can be understood that the rotation between the first elastic body 310 and the second elastic body 410 is similar to the rotation produced when two external gears mesh. For example, when the first elastic body 310 rotates clockwise, and the second elastic body 410 rotates counterclockwise, the optical fiber 20 moves relative to the through hole 211 and gradually extends out of the optical fiber loader 10, that is, the elongation length of the optical fiber 20 relative to the optical fiber loader 10 increases. For example, when the first elastic body 310 rotates counterclockwise, and the second elastic body 410 rotates clockwise, the optical fiber 20 moves relative to the through hole 211 and gradually retracts into the optical fiber loader 10, that is, the elongation of the optical fiber 20 relative to the optical fiber loader 10 decreases.

[0065] See Figure 3 , Figure 5 and Figure 7 In some embodiments, the first fixing mechanism 300 further includes a first rotating shaft 320, which passes through the first mounting hole 111 and is rotatably connected to the first mounting member 110. A first elastic body 310 is fixedly sleeved on the portion of the first rotating shaft 320 located in the first mounting hole 111, such that the first elastic body 310 is at least partially housed in the first mounting hole 111. For example, a rotating hole 113 and a clearance hole 114 may be provided on the first mounting member 110. Both the rotating hole 113 and the clearance hole 114 penetrate the side of the first mounting member 110, so that both the rotating hole 113 and the clearance hole 114 are connected to the first mounting hole 111 and the outside. Of course, the rotating hole 113 and the clearance hole 114 are also interconnected. There can be multiple clearance holes 114, which are evenly spaced along the circumference of the rotating hole 113. The first rotating shaft 320 is rotatably engaged with the rotating hole 113, thereby realizing the rotational connection between the first rotating shaft 320, the first elastic body 310, and the first mounting member 110. The first elastic body 310 will rotate relative to the first mounting member 110 following the first rotating shaft 320.

[0066] By providing a clearance hole 114, during the process of the first rotating shaft 320 being inserted horizontally into the rotating hole 113 and engaging with it, the first mounting member 110 can easily undergo expansion deformation, thereby reasonably increasing the diameter of the rotating hole 113 and allowing the first rotating shaft 320 to smoothly engage with it. After the first rotating shaft 320 has successfully engaged with the rotating hole 113, the first mounting member 110 can easily undergo contraction deformation, thereby reasonably reducing the diameter of the rotating hole 113, allowing the first rotating shaft 320 to be fixed in the rotating hole 113, ensuring that the first elastic body 310 can smoothly rotate relative to the first rotating shaft 320. At the same time, the clearance hole 114 can also play a role in more thorough cleaning.

[0067] See Figure 3 , Figure 5 and Figure 10 In some embodiments, the second fixing mechanism 400 further includes a second rotating shaft 420, which passes through the second mounting hole 212 and is rotatably connected to the second mounting member 210. A second elastic body 410 is fixedly sleeved on the portion of the second rotating shaft 420 located in the second mounting hole 212, such that the second elastic body 410 is at least partially housed in the second mounting hole 212. For example, the second mounting member 210 has a rotating groove 215, which connects the second mounting hole 212 to the outside. The rotating groove 215 can extend a certain length in the vertical direction. The rotating groove 215 is a circumferentially non-closed mechanism, such that there is a notch 2151 at one end of the rotating groove 215 near the first rotating shaft 320. The second rotating shaft 420 is installed from the notch 2151 into the rotating groove 215, that is, the second rotating shaft 420 is installed from top to bottom in the rotating groove 215 in the vertical direction. The second rotating shaft 420 is rotatably engaged with the rotating groove 215, thereby achieving a rotatable connection between the second rotating shaft 420, the second elastic body 410, and the second mounting member 210. The second elastic body 410 will rotate relative to the second mounting member 210 following the second rotating shaft 420.

[0068] See Figure 3 , Figure 5 and Figure 10 In some embodiments, the second fixing mechanism 400 further includes two knobs 430. The knobs 430 are located outside the second mounting hole 212 and the rotating groove 215, and are respectively fixedly connected to both ends of the second rotating shaft 420. By using the knobs 430, the user can apply a torque to the second rotating shaft 420 by holding the knobs 430, thereby driving the second elastic body 410 to rotate. Therefore, by controlling the rotation of the knobs 430, the first elastic body 310 and the second elastic body 410 can rotate, thereby driving the optical fiber 20 to move relative to the through hole 211, thus adjusting the extension length of the optical fiber 20 relative to the optical fiber loader 10.

[0069] See Figure 19 During the installation of the second fixing mechanism 400, the knob 430 and the second elastic body 410 can be installed onto the second rotating shaft 420, and then the second rotating shaft 420 with the knob 430 and the second elastic body 410 installed can be engaged with the rotating groove 215. Therefore, by setting the rotating groove 215, the assembly of the knob 430, the second elastic body 410 and the second rotating shaft 420 can be completed outside the second mounting mechanism 200. That is, the assembly of the second fixing mechanism 400 can be completed in the space outside the second mounting mechanism 200, thus avoiding interference caused by the second mounting mechanism 200, thereby improving the installation efficiency and accuracy of the second fixing mechanism 400.

[0070] It is understandable that the energy emitted by the laser acts on the stone through the head of the optical fiber 20, thereby breaking the stone. To maintain a better breaking effect, the head of the optical fiber 20 needs to maintain a reasonable distance from the stone at all times. During the stone breaking process, the head of the optical fiber 20 will continuously wear down, causing the distance between the optical fiber 20 and the stone to change. At this time, the knob 430 can be rotated to drive the first elastic body 310 and the second elastic body 410 to rotate, thereby precisely changing the extension length of the optical fiber 20 relative to the optical fiber loader 10. This allows for precise fine-tuning of the distance between the optical fiber 20 and the stone, ensuring that the head of the optical fiber 20 always maintains a reasonable distance from the stone, ultimately ensuring a better stone breaking effect. Since the optical fiber 20 can be quickly adjusted to a specified position by the joint rotation of the first elastic body 310 and the second elastic body 410, and the first elastic body 310 and the second elastic body 410 generate a reasonable clamping force on the optical fiber 20, the optical fiber 20 in the specified position can be prevented from continuing to slip relative to the through hole 211, thus improving the adjustment efficiency and accuracy of the extension length of the optical fiber 20.

[0071] See Figure 5In some embodiments, the sealing mechanism 600 has a sealing hole 633, which is interconnected with the through hole 211, and the optical fiber 20 passes through the sealing hole 633. When the force-applying member 140 applies a contact force to the sealing mechanism 600, causing the sealing mechanism 600 to abut between the force-applying member 140 and the guiding mechanism 500, the sealing mechanism 600 undergoes elastic deformation, reducing the diameter of the sealing hole 633. This results in an interference fit between the sealing hole 633 and the optical fiber 20, thereby sealing the sealing hole 633 and effectively preventing bodily fluids from leaking out of the optical fiber loader 10 through the sealing hole 633, thus improving the sealing performance of the optical fiber loader 10. It is understandable that when the force-applying component 140 stops applying the abutment force to the sealing mechanism 600, the elastic deformation of the sealing mechanism 600 can disappear, the diameter of the sealing hole 633 becomes larger, so that the sealing hole 633 and the optical fiber 20 form a gap fit relationship. This can reduce the fit resistance between the optical fiber 20 and the sealing hole 633, and also prevent the optical fiber 20 from breaking, thereby improving the installation efficiency and reliability of the optical fiber 20.

[0072] See Figure 5 and Figure 13 In some embodiments, the guiding mechanism 500 includes a guide seat 510 and a protruding ring 520. The optical fiber 20 passes through the guide seat 510. Both the guide seat 510 and the protruding ring 520 can have approximately circular cross-sections. The protruding ring 520 protrudes radially from the guide seat 510 and is disposed on the outer circumferential surface of the guide seat 510. The guide seat 510 is inserted into the second mounting member 210, and the protruding ring 520 is located outside the second mounting member 210, abutting against the second mounting member 210. This provides good positioning for the installation of the guiding mechanism 500, thereby improving the installation efficiency and accuracy of the guiding mechanism 500 relative to the second mounting member 210.

[0073] See Figure 5 and Figure 13 In some embodiments, the guide seat 510 has a guide hole 511, which includes a tapered hole 5111 and a cylindrical hole 5112. The cylindrical hole 5112 is closer to the second mounting hole 212 than the tapered hole 5111, so that the cylindrical hole 5112 and the second mounting hole 212 are in communication. Along the direction from the cylindrical hole 5112 to the tapered hole 5111, the cross-sectional dimensions and diameter of the cylindrical hole 5112 remain constant, while the cross-sectional dimensions and diameter of the tapered hole 5111 can be reduced.

[0074] See Figure 14 , Figure 15 and Figure 16In some embodiments, the sealing mechanism 600 can be integrally formed. The sealing mechanism 600 mates with the guide hole 511 and abuts against the guide seat 510 and the force-applying member 140 of the first mounting mechanism 100. The sealing mechanism 600 includes a sealing unit 610 and a limiting unit 620. The cross-sectional dimension of the limiting unit 620 is larger than that of the sealing unit 610. The sealing hole 633 is disposed on the sealing unit 610. The sealing unit 610 protrudes from the end face of the limiting unit 620. The sealing unit 610 mates with the guide hole 511, and the limiting unit 620 is located outside the guide hole 511 and abuts against the guide seat 510 and the force-applying member 140. Through the abutment between the limiting unit 620 and the guide seat 510, the installation of the sealing mechanism 600 can be effectively limited, thereby improving the installation efficiency and accuracy of the density mechanism. On the other hand, the limiting unit 620 can be located outside the guide hole 511 and effectively abut against the force-applying member 140, so that the sealing unit 610 can deform and the sealing hole 633 and the optical fiber 20 can form an interference fit relationship.

[0075] See Figure 14 , Figure 15 and Figure 16 In some embodiments, the sealing unit 610 includes a cylindrical segment 611 and a tapered segment 612. A sealing hole 633 is disposed in the tapered segment 612, and the cylindrical segment 611 connects the tapered segment 612 and the limiting unit 620. The cylindrical segment 611 is closer to the second mounting hole 212 than the tapered segment 612. Along the direction from the cylindrical hole 5112 to the tapered hole 5111, the cross-sectional dimension of the cylindrical segment 611 is constant, while the cross-sectional dimension of the tapered segment 612 decreases. The cylindrical segment 611 mates with the cylindrical hole 5112, and the tapered segment 612 mates with the tapered hole 5111. This improves the fitting accuracy and efficiency between the sealing unit 610 and the guide hole 511, and also facilitates the rapid and reasonable deformation of the tapered segment 612, thereby ensuring that the sealing hole 633 is interference-fitted with the optical fiber 20 and effectively blocked by the optical fiber 20.

[0076] See Figure 14 , Figure 15 and Figure 16In some embodiments, the tapered hole 5111 includes a first tapered segment 5111a and a second tapered segment 5111b, which are coaxially arranged. The first tapered segment 5111a connects the second tapered segment 5111b and the cylindrical segment 611, and the tapered angle of the first tapered segment 5111a is greater than that of the second tapered segment 5111b. This can be understood as the angle between the inner wall of the first tapered segment 5111a and the centerline of the cylindrical segment 611 being greater than the angle between the inner wall of the second tapered segment 5111b and the centerline of the cylindrical segment 611. Thus, during the compression process between the guide seat 510 and the tapered segment 612, it is easier for the tapered segment 612 to undergo sufficient radial deformation to reduce the diameter of the sealing hole 633, thereby enabling the sealing hole 633 to effectively form an interference fit with the optical fiber 20, ensuring effective sealing of the sealing hole 633 and improving the sealing performance of the optical fiber loader 10.

[0077] See Figure 14 , Figure 15 and Figure 16 In some embodiments, the sealing mechanism 600 is a split-connection, comprising a first sealing element 630 and a second sealing element 640, which are detachably connected. The first sealing element 630 is more flexible than the second sealing element 640. A sealing hole 633 is formed in the first sealing element 630, and the force-applying element 140 abuts against the second sealing element 640. It is understood that a portion of the second sealing element 640 forms the aforementioned limiting unit 620, and another portion of the second sealing element 640, excluding the limiting unit 620, together with a portion of the first sealing element 630, forms the cylindrical segment 611 of the sealing unit 610, while the other portion of the first sealing element 630 forms the aforementioned conical segment 612. By detachably connecting the first sealing element 630 and the second sealing element 640, the manufacturing difficulty of the sealing mechanism 600 can be reduced, thereby improving the processing efficiency and reducing manufacturing costs. The first sealing member 630 includes an insertion portion 631 and an abutment portion 632. The insertion portion 631 protrudes from one end of the abutment portion 632. A sealing hole 633 is located in the abutment portion 632, and the abutment portion 632 mates with the tapered hole 5111. The second sealing member 640 has an insertion hole 641, and the insertion portion 631 mates with the insertion hole 641. This allows for a detachable connection between the first sealing member 630 and the second sealing member 640. The abutment portion 632 is located outside the insertion hole 641 and abuts against the second sealing member 640 and the guide mechanism 500.

[0078] By creating a certain interference fit between the sealing hole 633 and the optical fiber 20, the sealing hole 633 can effectively seal the fiber to prevent liquid leakage, thereby improving the sealing performance of the optical fiber loader 10. Furthermore, during the process of the first elastic body 310 and the second elastic body 410 driving the optical fiber 20 to adjust its extension length, a reasonable frictional force is generated between the optical fiber 20 and the sealing hole 633, creating a certain damping. This allows the optical fiber 20 to stop at any specified position, further improving the adjustment accuracy of the extension length of the optical fiber 20 relative to the optical fiber loader 10, and also further improving the stability and reliability of the optical fiber 20's fixation.

[0079] During the loading of optical fiber 20 by optical fiber loader 10, the following assembly steps can be formed:

[0080] See Figure 17 and Figure 18 The first step involves assembling the sealing mechanism 600 outside the second mounting member 210. This avoids interference from the second mounting member 210 during the assembly of the sealing mechanism 600, thereby improving the assembly efficiency and accuracy of the sealing mechanism 600. After the sealing mechanism 600 is assembled, it can be inserted into the guide hole 511 through the second mounting hole 212. Specifically, the sealing mechanism 600 is first placed into the second mounting hole 212, and then pushed horizontally into the guide hole 511.

[0081] See Figure 19 The second step involves assembling the second fixing mechanism 400 outside the second mounting component 210, and then engaging the second rotating shaft 420 with the rotating groove 215 from top to bottom, thereby achieving the assembly of the second fixing mechanism 400 and the second mounting mechanism 200.

[0082] See Figure 20 The third step is to insert the optical fiber 20 into the through hole 211, the sealing hole 633, and the guide seat 510. At this time, since the first mounting mechanism 100 is not connected to the second mounting mechanism 200, the sealing mechanism 600 does not undergo elastic deformation, making the diameter of the sealing hole 633 larger than the diameter of the optical fiber 20. Therefore, the optical fiber 20 and the sealing hole 633 form a clearance fit relationship, thereby improving the installation efficiency and reliability of the optical fiber 20.

[0083] See Figure 21 and Figure 22The fourth step involves installing the first fixing mechanism 300 onto the first mounting member 110, and engaging the slot 1121 on the first mounting member 110 with the protrusion 220 on the second mounting mechanism 200 from top to bottom. This causes the first mounting member 110 to rotate around the protrusion 220, gradually moving the switch member 120 closer to the second mounting member 210. During this rotation, the force-applying member 140 gradually inserts into the second mounting hole 212, causing the force-applying curved surface 141 of the force-applying member 140 to abut against the limiting unit 620 of the sealing mechanism 600. This causes the sealing unit 610 of the sealing mechanism 600 to elastically deform, gradually reducing the diameter of the sealing hole 633, and also causing the first elastic body 310 to gradually move closer to the second elastic body 410. After the switch member 120 and the second mounting member 210 are engaged, the diameter of the sealing hole 633 is minimized, resulting in an interference fit with the optical fiber 20, thus ensuring the sealing performance of the optical fiber loader 10. On the other hand, the first elastic body 310 and the second elastic body 410 contact each other to clamp the optical fiber 20, thereby improving the stability and reliability of the optical fiber 20 fixation. At this time, the assembly of the optical fiber 20 and the optical fiber loader 10 is completed. When it is necessary to adjust the elongation length of the optical fiber 20 relative to the optical fiber loader 10, it can be rotated counterclockwise or clockwise to precisely adjust the elongation length of the optical fiber 20 relative to the optical fiber loader 10.

[0084] During assembly, when the position where the force-applying curved surface 141 is closest to the sealing hole 633 abuts against the sealing mechanism 600, the first mounting component 110 is rotated downwards. After the switch component 120 and the second mounting component 210 are snapped together, the position where the force-applying curved surface 141 is closest to the sealing hole 633 will pass over the sealing mechanism 600 without contacting it, thus creating a gap between the position where the force-applying curved surface 141 is closest to the sealing hole 633 and the sealing mechanism 600. This ensures that after the first mounting component 110 and the second mounting component 210 are assembled, the sealing mechanism 600 avoids generating excessive compressive force on the force-applying curved surface 141, thereby reasonably reducing the internal stress of the fiber optic loader 10 and improving the stability and reliability of the fiber optic loader 10 assembly.

[0085] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0086] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
