[0037] This utility model proposes a fiber optic conduit and coupler connection structure, which can be applied to medical equipment such as laser ablation systems, and can also be applied to other fields, which are not limited here.

[0038] Reference Figures 1 to 7 In one embodiment of this utility model, the fiber optic conduit and coupler connection structure includes a fiber optic conduit 10, a coupler 20, and a plug 30. The coupler 20 has an input end and an output end. The input end of the coupler 20 is suitable for connecting to a light source such as a laser generator through an optical transmission device such as a metal tube 40. The output end of the coupler 20 is provided with an interface 20a, and the interface 20a is recessed with a snap-fit ​​groove 20b. The plug 30 is located on one end of the fiber optic conduit 10. The plug 30 is provided with a buckle 321. The plug 30 is inserted into the interface 20a, and the buckle 321 is snapped into the snap-fit ​​groove 20b to connect the fiber optic conduit 10 and the coupler 20.

[0039] In this embodiment, as Figure 4 and Figure 5 As shown, the coupler 20 includes two or more housings and lens 25 combinations disposed within the housings. The coupler may or may not have multiple inner housings; no specific limitation is made here. The number of lenses 25 can be one, two, or more. Some or all of the lenses 25 can be interconnected or all can be independently positioned. Generally, combinations of lenses 25 with different functions are selected to achieve the coupling function; these can be collimating lenses, converging lenses, etc., and are not limited here. Furthermore, other optical components can be disposed within the coupler, depending on the specific coupling scenario.

[0040] Main reference Figure 3In this embodiment, the plug 30 may include an exposed portion and an insertion portion connected to the exposed portion. The buckle 321 may be provided on the insertion portion. The exposed portion may be provided with an operating part connected to the buckle 321. The operating part may be a suspended elastic pressing arm or a structure that controls the movement of the buckle 321 in other ways, which is not limited here.

[0041] It is understood that this utility model provides a fiber optic conduit and coupler insertion structure for a laser emitting device. The fiber optic conduit 10 and the coupler are connected by a snap-fit ​​method, which effectively improves the assembly and positioning accuracy of the fiber optic conduit 10 and the coupler. No additional screws or other locking parts are required for fixation, making disassembly and assembly more convenient and saving costs.

[0042] To further improve the positioning accuracy of the fiber optic conduit 10 and the coupler assembly, and to enhance the ease of assembly, such as... Figure 3 , Figures 6 to 7 As shown, in one embodiment, guide slopes 201 can be provided on both opposite inner sidewalls of the plug interface 20a, and the inclination of the two opposite outer sidewalls of the plug 30 insertion end is adapted to the inclination of the two guide slopes 201 respectively.

[0043] In this embodiment, the coupler 20 may include a base 21, a top cover 22, and a fixing block 23. The top cover 22 is placed on the base 21 and surrounds it to form a coupling cavity 20c and an input port 20d and an output port 20e that are respectively connected to the coupling cavity 20c. The input port 20d is adapted to be connected to a light source through a metal tube 40. The fixing block 23 is disposed at the output port 20e and surrounds the base 21 to form a plug interface 20a.

[0044] Furthermore, a pressure spring can be provided on the outer wall of the fixing block 23 opposite to the base 21, and the pressure spring presses the insertion end of the plug 30 onto the base 21. In this way, the reliability of the plug 30 and the coupler connection is greatly improved, which helps to improve the stability of the output energy.

[0045] To facilitate the removal of the fiber optic conduit 10 for storage and subsequent use, please refer to the following: Figure 3 In one embodiment, the plug 30 may include a plug body 31 and an elastic arm 32 disposed on the plug body 31. The elastic arm 32 is partially suspended, and a latch 321 is disposed on one end of the elastic arm 32. The other end of the elastic arm 32 is provided with a pressing part 322, which is exposed outside the insertion interface 20a and is used to drive the latch 321 to disengage from the locking groove 20b under the drive of external force. In this way, while ensuring the reliability of the latch 321 in the locking groove 20b, it is also convenient to remove the plug 30 from the fiber optic conduit 10.

[0046] During assembly, the operator simply needs to insert the plug 30 directly into the connector 20a of the coupler 20. After use, the operator only needs to press the pressing part 322 to disengage the latch 321 from the locking slot 20b, and then pull the plug 30 out.

[0047] Main reference Figure 4 In one embodiment, the coupler 20 may further include a guide seat 24 disposed at the insertion interface 20a, the guide seat 24 having a guide channel 24a communicating with the insertion interface 20a. The guide channel 24a is mainly used to guide the plug 30 to be inserted into the target position.

[0048] In this embodiment, as Figure 4 and Figure 5 As shown, two position sensors 26 can be disposed between the guide seat 24 and the sides of the base 21 and the top cover 22. Each position sensor 26 has a detection part with a receiving opening. Two position sensors 26 are provided, and each sensor 26 wraps around both sides of the insertion interface 20a through its receiving opening. Both the base 21 and the top cover 22 have through holes corresponding to the position of the insertion point. The positions of these through holes are adapted to correspond to the notch position on the plug 30 of the fiber optic conduit 10 when it is fully inserted, allowing light emitted from the detection part of the position sensor 26 to pass through. This arrangement enables precise detection of whether the plug 30 of the fiber optic conduit 10 is in the target position, greatly improving the accuracy of energy output.

[0049] In this embodiment, as Figure 4 As shown, the inner wall of the guide channel 24a is recessed with a relief opening 24b to allow the snap fastener 321 to smoothly engage in the snap-fit ​​groove 20b. To further improve the ease of assembly, the top surface of the relief opening 24b can be inclined, and the height of the relief opening 24b gradually decreases from the outside to the inside.

[0050] This utility model also proposes a medical device, referring to... Figure 1 The medical device includes a light source and a fiber optic conduit and coupler insertion structure. Both the light source and the coupler 20 are fixed on the mounting plate. The fiber optic conduit and coupler insertion structure is connected to the light source through a metal tube 40. The specific structure of the fiber optic conduit and coupler insertion structure is as described in the above embodiments. Since the laser emitting device proposed in this utility model includes all the solutions of all embodiments of the above fiber optic conduit and coupler insertion structure, it has at least the same technical effect as the above fiber optic conduit and coupler insertion structure, which will not be described in detail here.

[0051] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
