[0030] The technical solution provided by this invention has the following advantages:

[0031] 1. The fiber optic probe provided by the present invention includes a detection end and a connector, the detection end and the connector being connected by optical fiber communication, the connector including a housing, an adapter and a limiting element, the housing having spaced-apart support portions and protrusions, the adapter being at least partially installed in the housing; the limiting element being sleeved on the adapter, the limiting element being disposed in the housing, and the limiting element and the housing being configured to be detachably connected. By protruding the protruding structure toward the limiting element, the protruding structure on the housing is limited by the limiting element. A connecting part facing the housing is provided on the wall of the limiting element, and the supporting part and the connecting part are correspondingly abutted. The purpose of limiting the assembly of the housing and the adapter is achieved by limiting the assembly of the housing and the adapter through the limiting element. The protruding direction of the protruding structure intersects with the extension axis direction of the housing. The supporting part is arranged along the extension axis direction of the housing. The supporting part and the connecting part are correspondingly abutted. The extension surface of the supporting part and the extension surface of the connecting part are parallel. This creates intersecting limiting surfaces between the limiting element and the housing, strengthens the limiting alignment capability between the limiting element and the housing, avoids structural slippage and displacement, enhances the assembly accuracy during fiber optic probe installation, and improves the imaging accuracy and imaging effect of the system.

[0032] 2. The fiber optic probe provided by the present invention includes a first protrusion and a second protrusion in its protrusion structure. The first and second protrusions are spaced apart, and any protrusion is spaced apart from a support portion. Any protrusion abuts against the limiting element. By having the first and second protrusions work together to abut against the limiting element, the limiting and alignment capability between the housing and the limiting element is ensured, the assembly accuracy between the structures is enhanced, and thus the assembly capability of the fiber optic probe is improved.

[0033] 3. The fiber optic probe provided by the present invention further includes a limiting structure, which includes a first limiting part, a second limiting part, and a third limiting part. The first limiting part is formed on the wall surface of the adapter facing the limiting element; the second limiting part is formed on the wall surface of the tube facing the adapter; and the third limiting part is formed on the wall surface of the insulating part facing the adapter. The first limiting part abuts against the second and third limiting parts. By abutting against the second and third limiting parts, the adapter, tube, and insulating part are connected in a relatively positive position, ensuring the assembly accuracy between the structures and thus improving the assembly accuracy of the fiber optic probe. The extension surface of any limiting part is parallel to the extension direction of the adapter, allowing the adapter, tube, and insulating part to be slidably assembled, facilitating the assembly of the fiber optic probe structure.

[0034] 4. The fiber optic probe provided by this invention further includes a locking member, which is sleeved and installed on the adapter. The locking end of the locking member abuts against the tube body and the insulating component, which are disposed between the locking member and the flange. The locking member locks the tube body and the insulating component onto the adapter, thereby enhancing the compact arrangement of the structure. The locking member abuts against the tube body and the insulating component along the extension direction of the adapter and towards the flange, improving the alignment and connection between the adapter and the tube body and the insulating component.

[0035] 5. The confocal microscopy imaging system provided by the present invention includes a fiber optic probe. A limiting element is disposed between the adapter and the housing to improve the limiting contact between the adapter and the housing. The limiting element is engaged with a protruding structure on the housing to abut and limit the probe.

[0059] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0060] Example 1

[0061] This embodiment provides an optical fiber probe, which includes a detection end 1 and a connector 3, such as... Figure 1 As shown, the detection end 1 and the connector 3 are connected by optical communication. The detection end 1 includes a detection objective lens. An optical guide 2 is disposed between the detection objective lens and the connector 3. The optical guide 2 serves as an information transmission element to transmit the image information fed back by the detection objective lens to the connector 3.

[0062] like Figure 2 , Figure 3 as well as Figure 6 As shown, the housing 31 has a first channel 311, and the adapter 32 has a second channel 321. The extending directions of the first channel 311 and the second channel 321 are coaxially arranged. The first channel 311 and the second channel 321 are connected to provide assembly space for the optical guide 2. In this embodiment, the housing 31 is an outer polymer material component and is configured as a flexible component, while the adapter 32 is an optical fiber metal head and is configured as a rigid structure.

[0063] like Figures 1 to 4 , Figure 9 as well as Figure 10As shown, connector 3 includes a housing 31, an adapter 32, and a limiting element 34. The adapter 32 is at least partially installed inside the housing 31. The limiting element 34 is sleeved on the adapter 32 and is disposed inside the housing 31. The limiting element 34 and the housing 31 are configured for detachable connection. The housing 31 has spaced-apart support portions 312 and protruding structures. A connecting portion 341 facing the housing 31 is provided on the wall of the limiting element 34. The support portions 312 and the connecting portion 341 are correspondingly abutted. The protruding structure protrudes towards the limiting element 34, which can limit the limiting element 34 on the housing 31. This achieves the purpose of limiting the assembly of the housing 31 and the adapter 32 by limiting the assembly of the housing 31 and the adapter 32, strengthening the limiting alignment capability between the limiting element 34 and the housing 31, avoiding structural slippage, enhancing the assembly accuracy during fiber optic probe installation, and improving system imaging accuracy and effect. In this embodiment, the housing 31 and the limiting element 34 are coaxially arranged. The support portion 312 is formed inside the housing 31. There are two support portions 312, which are symmetrically arranged at intervals in the inner cavity of the housing 31. Correspondingly, the connecting portion 341 is formed on the outer side of the limiting element 34. There are two connecting portions 341, which are symmetrically arranged on the outer wall surface of the limiting element 34.

[0064] like Figure 3 , Figure 9 as well as Figure 10 As shown, the protruding direction of the protruding structure intersects with the extension axis direction of the housing 31. The support portion 312 is arranged along the extension axis direction of the housing 31. The support portion 312 and the connecting portion 341 are correspondingly abutted, and the extension surfaces of the support portion 312 and the connecting portion 341 are parallel. The extension surfaces of the support portion 312 and the connecting portion 341 are configured as planes. When the housing 31 and the limiting element 34 are assembled, the extension surfaces of the support portion 312 and the connecting portion 341 can be slidably arranged. Through the cooperation and abutment of the support portion 312 and the connecting portion 341, the protruding direction of the protruding structure is arranged towards the extension axis of the housing 31, thereby constructing intersecting limiting surfaces between the limiting element 34 and the housing 31 to improve the assembly accuracy of the fiber optic probe. During operation, the cooperation between the support part 312 and the connecting part 341 provides sufficient contact area for the limiting element 34 and the housing 31, which is adapted to the pressing action of the outer housing 31 to prevent slippage and deviation during the pressing process, thereby improving the stability and safety during operation.

[0065] In other alternative embodiments, the support portion 312 and the connecting portion 341 are configured as stepped surfaces that conform to each other, with the extension direction of the stepped surfaces being consistent with the extension direction of the housing 31.

[0066] like Figure 3As shown, the protruding structure includes a first protrusion 313 and a second protrusion 314, which are spaced apart. Each protrusion is spaced apart from the support portion 312, and each protrusion abuts against the limiting element 34. The limiting element 34 has a guide portion 342 and a recessed portion 343. The guide portion 342 and the first protrusion 313 are slidably connected. The guide portion 342 extends along the length of the limiting element 34, and the second protrusion 314 is installed within the recessed portion 343. By having the first protrusion 313 and the second protrusion 314 cooperate to abut against the limiting element 34, the limiting alignment capability between the housing 31 and the limiting element 34 is ensured, enhancing the assembly accuracy between the structures and thus improving the assembly capability of the fiber optic probe. The limiting element 34 slides against the first protrusion 313 via the guide portion 342, making the limiting element 34 and the housing 31 relatively orthogonally connected. The sliding connection also facilitates the assembly connection between the housing 31 and the limiting element 34. The second protrusion 314 is installed through the recess 343 to strengthen the connection and alignment between the housing 31 and the limiting element 34. The first protrusion 313 and the second protrusion 314 are spaced apart, with any protrusion protruding towards the limiting element 34. Thus, the first protrusion 313 and the second protrusion 314 form a limiting structure on the circumferential surface of the housing 31 for the internal limiting element 34, which helps to improve the assembly accuracy of the structure and thus improve the assembly accuracy of the fiber optic probe assembly.

[0067] In some implementations, such as Figure 3 , Figure 9 as well as Figure 10 As shown, the first protrusion 313 and the second protrusion 314 are symmetrically disposed in the inner cavity of the housing 31. The guide portion 342 and the recess 343 are respectively formed on the outer side of the limiting element 34. Each protrusion is a limiting protrusion, the guide portion 342 is a guide groove, the guide groove is disposed along the extending direction of the limiting element 34, and the recess 343 is used to accommodate and install the second protrusion 314.

[0068] The fiber optic probe provided in this embodiment, such as Figure 4 and Figure 5 As shown, it also includes a tube body 33, a chip component 35, and an insulating component 36. The tube body 33 is installed inside the limiting element 34 and is sleeved on the adapter 32. The tube body 33 and the adapter 32 are coaxially arranged. The chip component 35 is installed on the tube body 33, and the insulating component 36 is sleeved on the adapter 32. The pin end of the chip component 35 and the insulating component 36 are in contact with each other. The side of the insulating component 36 away from the detection end 1 is in contact with the limiting element 34 and the tube body 33.

[0069] like Figure 7 and Figure 9 , Figure 10As shown, the tube body 33 is provided with an assembly part 332, the chip component 35 is installed in the assembly part 332, and the limiting element 34 is provided with a clearance part 344. The assembly part 332 is disposed in the clearance part 344. In this embodiment, the assembly part 332 is configured as a groove structure, and the periphery of the groove structure is formed with a limiting protrusion. The chip component 35 is installed by limiting the mounting through the limiting protrusion. The clearance part 344 is configured as a semi-enclosed sliding groove structure. During assembly, the tube body 33 is slidably sleeved in the limiting element 34, and then the chip component 35 is connected in the assembly part 332.

[0070] like Figure 4 , Figure 5 as well as Figure 8 As shown, the chip 35 has pins, and the insulating member 36 has a mounting portion 361, with the pins disposed within the mounting portion 361. The insulating member 36 is used to insulate the pins of the chip 35 from the adapter 32 and the limiting element 34, preventing short circuits during assembly, promoting assembly reliability, and improving yield. In this embodiment, two pins and mounting portions 361 are provided correspondingly. The insulating member 36 and the limiting element 34 abut against each other. The pins are metal pins, and the inner side of the insulating member 36 abuts against the adapter 32. The insulating member 36 can be made of rubber, silicone, or polymer insulating material to achieve insulation, thereby allowing the chip 35 to be connected to an external device to identify the location of the detection light guide 2.

[0071] The fiber optic probe provided in this embodiment, such as Figure 4 As shown, it also includes a locking member 37, which is sleeved and installed on the adapter 32. The locking end of the locking member 37 abuts against the tube body 33 and the insulating member 36. The tube body 33 and the insulating member 36 are disposed between the locking member 37 and the flange portion 323. The locking member 37 locks the tube body 33 and the insulating member 36 onto the adapter 32 to enhance the compact arrangement of the structure. The locking member 37 abuts and locks the tube body 33 and the insulating member 36 along the extension direction of the adapter 32 and toward the position close to the flange portion 323, thereby improving the alignment and connection between the adapter 32 and the tube body 33 and the insulating member 36.

[0072] The fiber optic probe provided in this embodiment, such as Figure 4 , Figure 5 as well as Figure 11As shown, it also includes a stop member 38, which is sleeved on the tube body 33. The adapter 32 has a flange portion 323, which protrudes from the end of the adapter 32 away from the detection end 1. One side of the stop member 38 abuts against the flange portion 323, and the other side of the stop member 38 abuts against the limiting element 34. By blocking the limiting element 34 through the stop member 38, the contact area at the connection between the limiting element 34 and the adapter 32 can be correspondingly increased. The stop member 38 is sleeved and abuts against the outside of the tube body 33, and the stop member 38 serves to limit and align the tube body 33. In this embodiment, the stop member 38 is configured as an elastic gasket, which helps to prevent the connection from becoming loose.

[0073] like Figure 11 As shown, the stop member 38 includes a stop body 381 and a connecting protrusion 382. The connecting protrusion 382 is formed on the side of the stop body 381 away from the flange 323. The connecting protrusions 382 are centrally symmetrically distributed on the stop body 381. The limiting element 34 is provided with a receiving groove 347, which is correspondingly abutted against the connecting protrusion 382. The limiting element 34 is provided with a positioning part 346, which is an annular groove structure and is coaxially arranged with the stop body 381. In this embodiment, the stop body 381 is an annular structure, and the stop body 381 is configured with a reduced diameter in the direction toward the flange 323 to adapt to the structural dimensions of the limiting element 34 and the flange 323, which is beneficial to promote the uniform distribution of the force transmitted at the connection between the limiting element 34 and the adapter 32. There are two corresponding connecting protrusions 382 and positioning parts 346.

[0074] The fiber optic probe provided in this embodiment also includes a limiting structure, such as... Figures 6 to 8As shown, the limiting structure includes a first limiting part 322, a second limiting part 331, and a third limiting part 362. The first limiting part 322 is formed on the wall surface of the adapter 32 facing the limiting element 34; the second limiting part 331 is formed on the wall surface of the tube 33 facing the adapter 32; and the third limiting part 362 is formed on the wall surface of the insulating part 36 facing the adapter 32. The first limiting part 322 abuts against the second limiting part 331 and the third limiting part 362. By abutting against the second limiting part 331 and the third limiting part 362, the adapter 32, the tube 33, and the insulating part 36 are connected in a relatively positive position, ensuring the assembly accuracy of the structure and thus improving the stability of the fiber optic probe assembly. The extension surface of any limiting part is parallel to the extension direction of the adapter 32, allowing the adapter 32, the tube 33, and the insulating part 36 to be slidably assembled, facilitating the assembly of the fiber optic probe structure. To avoid structural wall thickness being too thin, the first limiting part 322 and the support part 312 are staggered and spaced apart in the circumferential direction of the adapter 32. The extension surface of the first limiting part 322 can intersect with the extension surface of the support part 312 to meet the strength requirements of the connection structure between the limiting element 34 and the housing 31.

[0075] like Figure 9 and Figure 10 As shown, the limiting element 34 is provided with a connecting joint 345, which is located at one end of the limiting element 34 near the flange portion 323, and the connecting joint 345 and the flange portion 323 are spaced apart. In this embodiment, the stop member 38 abuts against the connecting joint 345, and the stop member 38 is limited between the connecting joint 345 and the flange portion 323.

[0076] The fiber optic probe provided in this embodiment has a protruding structure protruding towards the limiting element 34, thereby limiting the protruding structure limiting element 34 on the housing 31. By providing a connecting part 341 facing the housing 31 on the wall of the limiting element 34, and the support part 312 and the connecting part 341 being correspondingly abutted, the purpose of limiting the assembly of the housing 31 and the adapter 32 is achieved by limiting the assembly of the housing 31 and the adapter 32 through the limiting element 34. The protruding direction of the protruding structure intersects with the extension axis direction of the housing 31. The support part 312 is arranged along the extension axis direction of the housing 31. The support part 312 and the connecting part 341 are correspondingly abutted. The extension surface of the support part 312 and the extension surface of the connecting part 341 are parallel to each other. This creates intersecting limiting surfaces between the limiting element 34 and the housing 31, strengthens the limiting alignment capability between the limiting element 34 and the housing 31, avoids structural slippage and displacement, enhances the stability of the fiber optic probe during installation, and promotes the imaging accuracy and imaging effect of the system.

[0077] The fiber optic probe provided in this embodiment is assembled as follows:

[0078] First, the light guide 2 is inserted and installed in the second channel 321; then, the stop 38 is sleeved on the tube body 33, the tube body 33 is sleeved in the limiting element 34, the stop 38 and the limiting element 34 are connected, and then the tube body 33 is sleeved on the adapter 32. The chip 35 is installed in the assembly part 332, and the pin end of the chip 35 is received by the mounting part 361; then, the locking member 37 abuts against the insulating member 36, and the insulating member 36, the tube body 33 and the limiting element 34 are locked together. Positioning element 34 is locked between flange portion 323 and locking member 37; then, housing 31 is wrapped around positioning element 34, first protrusion 313 inside housing 31 is slidably disposed in guide portion 342, recess 343 is assembled and connected to second protrusion 314, and support portion 312 on housing 31 and connecting portion 341 on positioning element 34 are abutted and engaged; finally, light guide 2 is positioned in first channel 311, and one end of light guide 2 is connected to detection end 1. This completes the assembly process of the fiber optic probe.

[0080] This embodiment provides a confocal microscopy imaging system, including the fiber optic probe of Embodiment 1. A limiting element 34 is disposed between the adapter 32 and the housing 31 to improve the limiting contact between them. The limiting element 34 is engaged with a protruding structure on the housing 31, and the supporting portion 312 on the housing 31 and the connecting portion 341 on the limiting element 34 also engage in limiting contact. This strengthens the limiting alignment capability between the limiting element 34 and the housing 31, preventing structural slippage and thus enhancing the stability of the fiber optic probe during installation. This improves the imaging accuracy and effect of the confocal microscopy imaging system.
