Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to an endoscope interface device and an endoscope system. Background Technology

[0002] An endoscope system is an instrument used for medical examinations and surgeries. It can be inserted into the body cavity through natural openings or small incisions, allowing doctors to directly observe internal organs and tissues. An endoscope system typically includes a light source and a camera unit. The light source provides illumination for the camera to capture images, the camera unit images the interior of the body cavity onto an imaging element, and then the image signal is transmitted via fiber optic cable to an image processing system. Finally, the processed image is output on a display device for doctors to observe and diagnose.

[0003] Image signals from endoscopic systems are transmitted via fiber optic interlocking. However, in related technologies, poor coaxiality and radial distance consistency in the fiber optic interlocking structure negatively impact the quality and stability of image signal transmission.

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0055] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0056] The specific structure and function of the endoscope system are described in detail below with reference to the accompanying drawings.

[0057] Reference Figure 1 , Figure 2 as well as Figure 3 This application also provides an endoscope system, comprising: an endoscope host 20, which processes detection data generated by the endoscope body 30. The endoscope host 20 is equipped with an endoscope interface device. Figure 1 and Figure 3 The docking cavity 341 in the middle is the structure of the endoscope interface device.

[0058] Combination Figure 4 The endoscope system in this embodiment of the application also includes an endoscope body 30, and the front end of the endoscope body 30 is provided with a camera structure for detecting the subject and generating detection data.

[0059] Reference Figure 5 The endoscope body 30 is provided with a second optical fiber terminal 500. The second optical fiber terminal 500 is movably inserted into the endoscope interface device. The second optical fiber terminal 500 and the first optical fiber terminal 310 of the endoscope interface device are connected in the docking cavity 341.

[0060] Thus, the images captured by the camera structure of the endoscope body 30 are transmitted to the endoscope host 20 for data processing via optical signals. The second fiber optic terminal 500 and the first fiber optic terminal 310 are mated in the mating cavity 341, which helps to improve the coaxiality of the two fiber optic terminals and reduce signal loss.

[0061] The following is combined with Figures 6 to 9 Describe in detail the specific structure and function of the endoscope interface device.

[0062] Combination Figure 6 and Figure 7 In some embodiments of this application, the endoscope interface device includes: a mounting base 100, an elastic element 200, and an optical fiber assembly 300.

[0063] Mounting base 100 provides a mounting position for fiber optic assembly 300 and elastic element 200, and mounting base 100 is disposed on the housing of endoscope host 20.

[0064] Mounting base 100 is configured to form mounting through hole 101 to provide mounting position for fiber optic assembly 300.

[0065] The fiber optic assembly 300 is used to realize fiber optic transmission. A portion of the fiber optic assembly 300 is housed within a mounting through-hole 101, with one end of the fiber optic assembly 300, facing away from the mating end, extending to the outside of the mounting through-hole 101. There is a gap between the mating end of the fiber optic assembly 300 and the wall of the mounting through-hole 101, allowing the mating end of the fiber optic assembly 300 to move radially within the mounting through-hole 101 to a certain extent.

[0066] The elastic element 200 is located inside the mounting through hole 101 and is sleeved on the outside of the fiber optic assembly 300; one end of the elastic element 200 is fixed relative to the mounting base 100, and the other end of the elastic element 200 is connected to the fiber optic assembly 300.

[0067] For example, the elastic element 200 can be a spring, which has a stable structure and low cost.

[0068] For example, the elastic element 200 can be an elastic sleeve, such as a silicone sleeve, which is lightweight.

[0069] The elastic element 200 in this embodiment is provided, which simplifies the structure of the endoscope interface device.

[0070] The elastic element 200 is constructed to have a radial elastic force, so that when the fiber optic assembly 300 is connected, the elastic element 200 deforms radially, allowing the radial position of the connection end of the fiber optic assembly 300 to change elastically, thereby making the fiber optic assembly 300 coaxial with the second fiber optic terminal 500 of the mirror body 30, ensuring the quality and stability of image signal transmission.

[0071] Moreover, the mating end of the fiber optic assembly 300 is movable under the action of the elastic element 200, so that the radial position of the fiber optic assembly 300 can adapt to the positional change of the second fiber optic terminal 500 of the mirror body 30, which helps to improve the smoothness of the insertion of the mirror body 30 and reduce the possibility of jamming problems in the mirror body 30.

[0072] In some embodiments, the elastic element 200 is also configured to have an axial elastic force, so that the fiber optic assembly 300 has a certain axial range of motion. When the mirror body 30 is inserted, the fiber optic assembly 300 can move axially to buffer the axial insertion force of the mirror body 30, so that the fiber optic assembly 300 and the second fiber optic terminal 500 of the mirror body 30 are elastically connected, which helps to protect the fiber optic terminal and avoid rigid connection that is easy to damage the fiber optic terminal.

[0073] Continue to refer to Figure 6 and Figure 7 In some embodiments of this application, the mounting base 100 includes a housing 110, and the housing 110 is provided with a first through hole 111. The first through hole 111 can be a circular hole.

[0074] The mating end of the optical fiber assembly 300 is located inside the first through hole 111 and is spaced from the hole wall of the first through hole 111, so that the mating end of the optical fiber assembly 300 can move radially within the first through hole 111.

[0075] Mounting through hole 101 includes a first through hole 111.

[0076] In this embodiment, the mounting base 100 forms a first through hole 111 by providing a housing 110, and the first through hole 111 is part of the mounting through hole 101. The mating end of the optical fiber assembly 300 is located in the first through hole 111 to support the optical fiber assembly 300 and provide space for radial movement of the mating end of the optical fiber assembly 300.

[0077] In some embodiments, the mounting base 100 further includes a bracket 120, which is fixedly connected to the housing 110; the bracket 120 is located at one end of the housing 110. The bracket 120 is provided with a second through hole 121, which is axially opposite to the first through hole 111. The second through hole 121 can be a circular hole. The mounting through hole 101 also includes the second through hole 121.

[0078] The endoscope interface device also includes a limiting ring 400, which is fixed within the second through hole 121. The channel 401 of the limiting ring 400 allows the end of the fiber optic assembly 300 facing away from the docking end to pass through to the outside of the mounting through hole 101.

[0079] The elastic element 200 abuts against the limiting ring 400, thereby fixing the elastic element 200 relative to the mounting base 100.

[0080] The second through hole 121 may include a first hole segment 1211, which is fixedly connected to the limiting ring 400. For example, the limiting ring 400 is interference-fitted with the first hole segment 1211.

[0081] The second through hole 121 may further include a second hole segment 1212, which is located at the end of the first hole segment 1211 facing the first through hole 111. The diameter of the second hole segment 1212 is larger than the diameter of the first hole segment 1211, such that a limiting step 122 is formed at the connecting end of the first hole segment 1211 and the second hole segment 1212.

[0082] A limiting boss 410 is formed on the outer surface of the limiting ring 400. The limiting boss 410 has two opposite ends along the axial direction of the channel 401. One end of the limiting boss 410 abuts against the limiting step 122 to limit the insertion of the limiting ring 400 into the first hole segment 1211. The other end of the limiting boss 410 abuts against the elastic member 200 to fix the elastic member 200 relative to the mounting base 100.

[0083] The second through hole 121 may also include a third hole segment 1213, the diameter of which may be larger than that of the second hole segment 1212, so that at least a portion of the elastic member 200 and the optical fiber assembly 300 are located within the third hole segment 1213, and space is provided for the radial deformation of the elastic member 200 and the radial movement of the optical fiber assembly 300.

[0084] Therefore, in this embodiment of the application, the mounting base 100 forms a second through hole 121 by setting a bracket 120. The second through hole 121 is part of the mounting through hole 101, and a limit ring 400 is fixed inside it to provide an abutment position for the elastic member 200, so that the elastic member 200 is fixed relative to the mounting base 100.

[0085] Continue to refer to Figure 6 A guide portion 600 is provided on the side of the outer shell 110 away from the bracket 120 to provide guidance for the insertion of the mirror body.

[0086] In some implementations, the optical fiber assembly 300 includes a first optical fiber terminal 310 and an optical fiber sleeve 320.

[0087] The fiber optic sleeve 320 is configured to form a receiving through hole 321, and the mating end of the first fiber optic terminal 310 is fixed in the receiving through hole 321 to fix and support the first fiber optic terminal 310.

[0088] There is a gap between the fiber optic sleeve 320 and the wall of the first through hole 111, so that the fiber optic sleeve 320 and the first fiber optic terminal 310 inside the fiber optic sleeve 320 can move radially within the first through hole 111 to adjust the radial position of the first fiber optic terminal 310 and improve the coaxiality of the first fiber optic terminal 310 and the second fiber optic terminal 500 of the mirror body 30.

[0089] The fiber optic assembly 300 of this application embodiment is provided with a fiber optic sleeve 320 and a receiving through hole 321 in the fiber optic sleeve 320, so that the mating end of the first fiber optic terminal 310 is fixed in the receiving through hole 321. This not only protects the mating end of the first fiber optic terminal 310, but also provides mating space for fiber optic splicing.

[0090] A portion of the elastic element 200 is fitted onto the outside of the fiber optic sleeve 320, and the other end of the elastic element 200 abuts against the fiber optic sleeve 320. With this configuration, when the second fiber optic terminal 500 of the mirror body 30 aligns with the first fiber optic terminal 310, even if there is an angular offset between them, when the second fiber optic terminal 500 of the mirror body 30 is inserted into the receiving through hole 321, the elastic element 200 undergoes radial deformation due to a certain angle of radial force. This causes the fiber optic sleeve 320 and the first fiber optic terminal 310 within the fiber optic sleeve 320 to move radially, allowing the mirror body 30 to be smoothly inserted. Huakeyi improves the coaxiality of the first fiber optic terminal 310 and the second fiber optic terminal 500 of the mirror body 30.

[0091] Continue to refer to Figure 6 and Figure 7 The fiber optic sleeve 320 has a first end and a second end opposite to each other along the axial direction of the mounting through hole 101. The first end of the fiber optic sleeve 320 is away from the elastic member 200, and the first end of the fiber optic sleeve 320 is configured to form a guide slope 322, which faces the receiving through hole 321. It can be understood that the first end of the fiber optic sleeve 320 forms a guide slope 322 within the receiving through hole 321.

[0092] Along the length of the receiving through hole 321, and from the elastic member 200 to the first end of the fiber optic sleeve 320, that is, from the second end of the fiber optic sleeve 320 to the first end, the guide slope 322 is inclined toward the outside of the receiving through hole 321.

[0093] exist Figure 7 In the middle, along the length direction of the receiving through hole 321, from left to right, the guide slope 322 is inclined toward the outside of the receiving through hole 321.

[0094] In this embodiment, a guide slope 322 is provided at the first end of the fiber optic sleeve 320 to guide the insertion of the second fiber optic terminal 500 of the mirror body 30 into the receiving through hole 321, thereby improving the smoothness of the insertion of the second fiber optic terminal 500 of the mirror body 30.

[0095] In some embodiments, the fiber optic sleeve 320 forms a limiting protrusion 323 within the receiving through hole 321. For example, a step is provided within the receiving through hole 321 to form the limiting protrusion 323; or, for another example, a protrusion is provided within the receiving through hole 321 to form a limiting boss 410.

[0096] The fiber optic assembly 300 also includes a retaining ring 330, which is fixedly connected to the fiber optic sleeve 320 to press the first fiber optic terminal 310 against the limiting protrusion 323, thereby fixing the first fiber optic terminal 310 in the receiving through hole 321.

[0097] The retaining ring 330 allows the first optical fiber terminal 310 to pass through the receiving through hole 321.

[0098] For example, the fixing ring 330 is threadedly connected to the fiber optic sleeve 320. The outer side of the fixing ring 330 is provided with an external thread, and the end of the receiving through hole 321 that is away from the guide slope 322 is provided with an internal thread, so that the fixing ring 330 and the receiving through hole 321 are threadedly connected. This not only makes the connection stable, but also facilitates disassembly, maintenance and replacement of the first fiber optic terminal 310.

[0099] For example, the fixing ring 330 is snapped into the fiber optic sleeve 320, and the connection method is simple and reliable.

[0100] For example, the fixing ring 330 and the fiber optic sleeve 320 are interference-fitted, making the connection between the fixing ring 330 and the fiber optic sleeve 320 simple and stable.

[0101] In some possible implementations, the outer surface of the fiber optic sleeve 320 is configured to form a first protrusion 324, which abuts against the other end of the elastic member 200.

[0102] For example, an annular protrusion is formed on the outer surface of the fiber optic sleeve 320 to form a first protrusion 324.

[0103] The first protrusion 324 is spaced from the second end of the fiber optic sleeve 320, so that part of the elastic member 200 can be fitted onto the fiber optic sleeve 320, and the radial deformation of the elastic member 200 can drive the fiber optic sleeve 320 to move radially.

[0104] In this embodiment, by providing a first protrusion 324 on the outer surface of the fiber optic sleeve 320 and abutting against the elastic member 200, the elastic member 200 is confined between the first protrusion 324 and the limiting ring 400.

[0105] In some embodiments of this application, the outer surface of the fiber optic sleeve 320 is configured to form a second protrusion 325, which is used to abut against the mounting base 100.

[0106] For example, an annular protrusion is formed on the outer surface of the fiber optic sleeve 320 to form a second protrusion 325.

[0107] Reference Figure 7 The second protrusion 325 has a gap with the first protrusion 324, which helps to reduce the weight of the fiber optic sleeve 320.

[0108] Reference Figure 8 and Figure 9 The second protrusion 325 and the first protrusion 324 can be connected to form an integral unit, which helps to improve the structural strength of the fiber optic sleeve 320.

[0109] In this embodiment, a second protrusion 325 is provided on the outer surface of the fiber optic sleeve 320, which abuts against the outer shell 110, thereby limiting the fiber optic assembly 300 and preventing the fiber optic sleeve 320 from protruding out of the mounting base 100.

[0110] Combination Figure 6 and Figure 7 In some embodiments, the second protrusion 325 abuts against the end of the housing 110 toward the bracket 120.

[0111] Combination Figure 8 and Figure 9 In other embodiments, the end of the bracket 120 is provided with a third protrusion 123, and the second protrusion 325 abuts against the third protrusion 123. Figure 8 and Figure 9 In the structure shown, the mounting base 100 may consist only of the bracket 120.

[0112] In some embodiments, the fiber optic assembly 300 further includes a sleeve 340, which is installed within a receiving through-hole 321.

[0113] For example, the sleeve 340 can be a ceramic sleeve 340.

[0114] The sleeve 340 can be a C-shaped ring, which is installed in the receiving through hole 321. In this way, the sleeve 340 is designed with interference fit, relying on its own tension to open and ensure that the first fiber optic terminal 310 and the second fiber optic terminal 500 of the mirror body 30 are coaxial.

[0115] A portion of the first optical fiber terminal 310 extends into the sleeve 340, and the first optical fiber terminal 310 and the end of the sleeve 340 away from the elastic member 200 are spaced apart to form a mating cavity 341.

[0116] The docking cavity 341 is used for docking the first optical fiber terminal 310 and the second optical fiber terminal 500 of the mirror body 30.

[0117] In this embodiment of the application, a sleeve 340 is provided so that a portion of the first optical fiber terminal 310 extends into the sleeve 340 and a mating cavity 341 is formed inside the sleeve 340, so that the second optical fiber terminal 500 of the mirror body 30 and the first optical fiber terminal 310 are mated.
