Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a connection unit of an endoscope system, a host computer of an endoscope system, and an endoscope system. Background Technology

[0002] For endoscopic systems such as upper or lower gastrointestinal endoscopes, the light transmitted from the main unit of the endoscopic system is generally transmitted into the human body through the built-in illumination component of the endoscope, providing the necessary bright environment for the camera element in the dark environment of the human body, capturing images of the patient's diseased tissue, recording them through the image sensor at the back of the camera element and transmitting them to the main unit for further processing, and finally displaying them on the monitor for doctors to diagnose.

[0003] In some cases, the main unit is compatible with multiple endoscopes, and the endoscopes and main unit are frequently interchanged. To ensure that the endoscope does not detach from the main unit during use, the endoscope and main unit are often connected by threads or locked by a mechanical structure. However, this connection method makes disassembly complicated after use, which greatly affects the user experience for medical staff.

[0004] With technological advancements, methods have emerged that utilize elastic mechanisms in conjunction with spherical force transmission components to enable rapid replacement between the mirror body and the main unit. However, the choice and structural form of the elastic mechanism determine the complexity and reliability of the connection unit used to connect the mirror body and the main unit. Therefore, how to ensure stability during frequent docking between the mirror body and the main unit, while simultaneously maintaining a simple structure and high reliability of the connection unit, is a pressing issue that needs to be addressed.

[0008] A limiting assembly includes a force-transmitting component and a limiting spring. The force-transmitting component is movably disposed within the receiving hole. The force-transmitting component protrudes from both the first and second openings. The limiting spring is connected to the first connecting surface, and the portion of the force-transmitting component protruding from the first opening abuts against the limiting spring, such that when the connecting unit and the mating unit are assembled, the portion of the force-transmitting component protruding from the second opening abuts against the mating unit.

[0009] In some embodiments, the limiting spring includes a first part, a second part, and a transition part located between the first part and the second part.

The transition part has a first end and a second end, the first end being connected to the first part, the second end being connected to the second part, and the second end being closer to the first connecting surface than the first end.

[0010] In some of these embodiments, the number of the connecting portions is one or more, and the target connecting portion is any one of the connecting portions;

[0011] For the target connection part, its first connection surface is set as a plane, and multiple first connection surfaces are provided and arranged in parallel.

[0014] In some embodiments, multiple connecting portions and limiting components are provided, and they correspond one-to-one. All the connecting portions are used to surround the mating unit and are spaced apart.

[0015] In some embodiments, the second connecting surface of a portion of the connecting portion is configured as a connecting plane adapted to the surface of the mating unit, while the second connecting surface of another portion of the connecting portion is configured as a connecting arc surface adapted to the surface of the mating unit.

[0016] Secondly, embodiments of this application provide a host for an endoscope system, the host including the connection unit as described in the first aspect.

[0017] Thirdly, embodiments of this application provide an endoscope system, including a host, an endoscope body, and a connection unit as described in the first aspect, wherein one of the host and the endoscope body includes the connection unit, and the other of the host and the endoscope body includes a mating unit.

[0018] In some embodiments, the connecting unit includes a first anti-rotation portion, and the mating unit includes a second anti-rotation portion, the first anti-rotation portion being connected to the second anti-rotation portion to restrict the connecting unit from rotating around the mating unit.

[0019] In some embodiments, the first anti-rotation part is configured as an anti-rotation key, and the second anti-rotation part is configured as an anti-rotation groove; or, the first anti-rotation part is configured as an anti-rotation groove, and the second anti-rotation part is configured as an anti-rotation key.

[0020] In some embodiments, the side of the anti-rotation groove opening is chamfered, and the anti-rotation key can enter the anti-rotation groove through the chamfer.

[0021] In some embodiments, multiple first anti-rotation portions and multiple second anti-rotation portions are provided, and the two correspond one-to-one. The multiple first anti-rotation portions are arranged around the mating unit and spaced apart.

[0022] The connecting unit of the endoscope system provided in this application has the following advantages: Since the connecting part is located on one side of the mating unit, the connecting part has a first connecting surface facing away from the mating unit and a second connecting surface facing the mating unit. The connecting part is provided with a receiving hole, which has a first opening formed on the first connecting surface and a second opening formed on the second connecting surface. The limiting component includes a force transmission member and a limiting spring. The force transmission member is movably disposed in the receiving hole. The force transmission member protrudes from the first opening and the second opening. The limiting spring is connected to the first connecting surface. Therefore, the portion of the force transmission member protruding from the first opening abuts against the limiting spring, so that the portion of the force transmission member protruding from the second opening abuts against the mating unit, thereby effectively limiting the mating unit and achieving a stable connection between the endoscope body and the main unit.

[0023] Furthermore, since the first opening of the receiving hole and the limiting spring are both located on the first connecting surface, the structure of the connecting unit can be made simpler, and the connecting part can be easily processed. During assembly, it is easy to ensure the relative positional accuracy of the limiting spring and the first opening. It is only necessary to connect the limiting spring to the first connecting surface and make the part of the force transmission component protruding from the first opening abut against the limiting spring. The assembly process is simple and convenient.

[0053] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0054] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0055] Furthermore, the terms "first" and "second" are used 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 as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0056] In this specification, references to "one embodiment," "some embodiments," or simply "embodiment" mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. Furthermore, in one or more embodiments, specific features, structures, or characteristics may be combined in any suitable manner.

[0057] To illustrate the technical solution of this application, the following description is provided in conjunction with specific accompanying drawings and embodiments.

[0058] With technological advancements, the use of elastic mechanisms in conjunction with spherical force transmission components has emerged to enable rapid replacement between the mirror body and the main unit. However, the selection and structural form of the elastic mechanism determine the complexity and reliability of the connection unit used to connect the mirror body and the main unit. Therefore, how to ensure stability during frequent docking between the mirror body and the main unit, while simultaneously maintaining a simple structure and high reliability of the connection unit, is a pressing issue that needs to be addressed.

[0059] In view of this, this application provides a connection unit for an endoscope system, a main unit for an endoscope system, and an endoscope system. Since the connection part is used to be located on one side of the mating unit, the connection part has a first connection surface facing away from the mating unit and a second connection surface facing the mating unit. The connection part is provided with a receiving hole, which has a first opening formed on the first connection surface and a second opening formed on the second connection surface. The limiting component includes a force transmission member and a limiting spring. The force transmission member is movably disposed in the receiving hole. The force transmission member protrudes from both the first and second openings. The limiting spring is connected to the first connection surface. Therefore, the portion of the force transmission member protruding from the first opening abuts against the limiting spring, so that the portion of the force transmission member protruding from the second opening abuts against the mating unit, thereby effectively limiting the mating unit and achieving a stable connection between the endoscope body and the main unit.

[0060] Furthermore, since the first opening of the receiving hole and the limiting spring are both located on the first connecting surface, the structure of the connecting unit can be made simpler, and the connecting part can be easily processed. During assembly, it is easy to ensure the relative positional accuracy of the limiting spring and the first opening. It is only necessary to connect the limiting spring to the first connecting surface and make the part of the force transmission component protruding from the first opening abut against the limiting spring. The assembly process is simple and convenient.

[0061] Please refer to Figures 1 to 5 In a first aspect, embodiments of this application provide a connection unit 100 for an endoscope system. The endoscope system includes a host 1000 and a scope 2000. One of the host 1000 and the scope 2000 includes the connection unit 100, and the other of the host 1000 and the scope 2000 includes a mating unit 2100.

[0062] The connecting unit 100 and the mating unit 2100 can be plugged together. In this embodiment, the main unit 1000 includes the connecting unit 100, and the mirror body 2000 includes the mating unit 2100.

[0063] The connection unit 100 includes a connection base 10 and a limiting component.

[0064] The connecting seat 10 includes a connecting portion 11, which can be disposed on the side of the mating unit 2100. The connecting portion 11 has a first connecting surface 111 and a second connecting surface 112 facing away from the mating unit 2100. The first connecting surface 111 can face away from the mating unit 2100, and the second connecting surface 112 can face the mating unit 2100. The connecting portion 11 is provided with a receiving hole, which has a first opening formed on the first connecting surface 111 and a second opening formed on the second connecting surface 112.

[0065] One or more connecting parts 11 may be provided. When multiple connecting parts 11 are provided, the multiple connecting parts 11 may be arranged around the mating unit 2100 and spaced apart. Multiple receiving holes may be provided.

[0066] The limiting assembly includes a force transmission member 20 and a limiting spring 30. The force transmission member 20 is movably disposed in the receiving hole. The force transmission member 20 protrudes from the first opening and the second opening. The limiting spring 30 is connected to the first connecting surface 111, and the portion of the force transmission member 20 protruding from the first opening abuts against the limiting spring 30, so that when the connecting unit 100 and the mating unit 2100 are assembled, the portion of the force transmission member 20 protruding from the second opening abuts against the mating unit 2100.

[0067] The force transmission element 20 can be a spherical or cylindrical body, such as a stainless steel ball. When multiple receiving holes are provided, multiple force transmission elements 20 can also be provided, with one force transmission element 20 installed in each receiving hole.

[0068] The limiting spring 30 can be a flexible metal spring or a flexible plastic spring, etc. The limiting spring 30 and the first connecting surface 111 can be connected by means of bonding, welding, screw connection or bolt connection, such as by pin and screw connection. It can be configured such that one end of the limiting spring 30 is connected to the first connecting surface 111, and the other end of the limiting spring 30 abuts against the force transmission member 20. Under the action of the elastic force of the limiting spring 30, the part of the force transmission member 20 protruding from the first orifice is kept in abutting state with the limiting spring 30, and the part of the force transmission member 20 protruding from the second orifice is kept in abutting state with the mating unit 2100.

[0069] In this case, the portion of the force transmission member 20 protruding from the second orifice is not parallel to the bearing direction of the mating unit 2100 and the insertion direction of the connecting unit 100 and the mating unit 2100. For example, the portion of the force transmission member 20 protruding from the second orifice may be perpendicular to the bearing direction of the mating unit 2100 and the insertion direction of the connecting unit 100 and the mating unit 2100.

[0070] Since the part of the force transmission component 20 protruding from the second opening abuts against the mating unit 2100, the connecting unit 100 and the mating unit 2100 can be kept in a plugged state, thereby achieving a stable connection between the mirror body 2000 and the host 1000.

[0071] The portion of the force transmission member 20 protruding from the second opening can directly abut against the outer surface of the mating unit 2100. Alternatively, the mating unit 2100 is provided with a locking groove 2101, and the portion of the force transmission member 20 protruding from the second opening is located within the locking groove 2101 and abuts against the inner wall surface of the locking groove 2101. The mating unit 2100 may include a mating seat 2110.

[0072] Since the first opening of the receiving hole and the limiting spring 30 are both located on the first connecting surface 111, the structure of the connecting unit 100 can be made simpler, the connecting part 11 can be processed more easily, and the relative positional accuracy of the limiting spring 30 and the first opening can be guaranteed during assembly.

[0073] As can be seen from the above, the connecting unit 100 of the endoscope system provided in this application embodiment has a connecting part 11 for being disposed on one side of the mating unit 2100. The connecting part 11 has a first connecting surface 111 facing away from the mating unit 2100 and a second connecting surface 112 facing the mating unit 2100. The connecting part 11 is provided with a receiving hole, which has a first opening formed on the first connecting surface 111 and a second opening formed on the second connecting surface 112. The limiting component includes a force transmission member 20 and a limiting spring. The plate 30 and the force transmission member 20 are movably disposed in the receiving hole. The force transmission member 20 protrudes from the first hole and the second hole. The limiting spring 30 is connected to the first connecting surface 111. Therefore, the part of the force transmission member 20 protruding from the first hole abuts against the limiting spring 30, so that the part of the force transmission member 20 protruding from the second hole abuts against the mating unit 2100, thereby effectively limiting the mating unit 2100 and achieving a stable connection between the lens body 2000 and the host 1000.

[0074] Since the first opening of the receiving hole and the limiting spring 30 are both located on the first connecting surface 111, the structure of the connecting unit 100 can be made simpler, and the connecting part 11 can be easily processed. During assembly, it is easy to ensure the relative positional accuracy of the limiting spring 30 and the first opening. It is only necessary to connect the limiting spring 30 to the first connecting surface 111 and make the part of the force transmission member 20 protruding from the first opening abut against the limiting spring 30. The assembly process is simple and convenient.

[0075] The connection unit 100 of the endoscope system provided in this application embodiment provides a holding force for the endoscope body 2000 inserted into the host 1000 during the docking process by using a limiting spring 30 in combination with a force transmission component 20. By adjusting the structure and hardness of the limiting spring 30, it is possible to ensure that the endoscope body 2000 does not fall off during use, while also providing a light and easy feel when pulling out the endoscope body 2000 after use. Thus, it is possible to ensure the stability of the endoscope body 2000 and the host 1000 during the docking process while realizing frequent docking between the endoscope body 2000 and the host 1000, making its structure simple and highly reliable.

[0076] Please refer to this as well. Figures 6 to 8In this embodiment, the limiting spring 30 includes a first part 31, a second part 32, and a transition part 33 located between the first part 31 and the second part 32. The first part 31 is connected to the first connecting surface 111, and the portion of the force transmission member 20 protruding from the first opening abuts against the second part 32. The transition part 33 has a first end 331 and a second end 332. The first end 331 is connected to the first part 31, and the second end 332 is connected to the second part 32. The second end 332 is closer to the first connecting surface 111 than the first end 331.

[0077] By adopting the above scheme, after the first part 31 is connected to the first connecting surface 111, the second part 32 can apply a greater force to the force transmission member 20, so that the part of the force transmission member 20 protruding from the second opening can more tightly abut against the mating unit 2100, and the structure of the limiting spring 30 is relatively simple.

[0078] It should be noted that when the limiting spring 30 is not connected to the first connecting surface 111, due to the presence of the transition part 33, there is a step difference between the surface of the first part 31 that is used to connect with the first connecting surface 111 and the surface of the second part 32 that is used to abut against the force transmission member 20. The function of the step difference is to provide a preload force to the force transmission member 20 in the non-working state based on the fact that the first connecting surface 111 is a plane. The transition part 33 can also provide rebound resistance under the premise that the hardness and thickness of the limiting spring 30 are relatively low to improve the feel.

[0079] Optionally, the shape of the transition portion 33 may include, but is not limited to, an arc, a reverse concave shape, and a triangle.

[0080] To facilitate the manufacture of the limiting spring 30, the first part 31, the second part 32, and the transition part 33 are integrally formed.

[0081] This design facilitates the manufacture of the limiting spring 30, which in turn allows the limiting spring 30 to have good elasticity.

[0082] For example, the first part 31, the second part 32, and the transition part 33 can be integrally formed by injection molding, casting, stamping, or machining.

[0083] For example, the limiting spring 30 can be manufactured by a one-time stamping process.

[0084] Please refer to Figures 1 to 10 Among them, some of the mating units 2100 have arc surfaces. During use, multiple force transmission components 20 need to abut against different positions of the arc surface to ensure a stable connection between the mirror body 2000 and the host 1000.

[0085] Therefore, the number of connecting parts 11 is one or more, and the target connecting part is any one of the connecting parts 11; for the target connecting part, its first connecting surface 111 is set as a plane, multiple first connecting surfaces 111 are provided, and multiple first connecting surfaces 111 are arranged in parallel, wherein the distances between two first connecting surfaces 111 and the mating unit 2100 are not equal, and the second connecting surface 112 is set as a connecting arc surface adapted to the surface of the mating unit 2100; multiple receiving holes, force transmission members 20 and limiting spring pieces 30 are provided, and the limiting spring pieces 30 are arranged in a one-to-one correspondence with the force transmission members 20, and the axis of the receiving hole is perpendicular to the first connecting surface 111.

[0086] By adopting the above scheme, not only can the multiple force transmission components 20 in the target connection part abut against different positions on the surface of the mating unit 2100, ensuring the stable connection between the mirror body 2000 and the host 1000, but also the axes of all the receiving holes in the target connection part are perpendicular to the first connection surface 111, thereby making the processing of the receiving holes more convenient.

[0087] It is understandable that the different force transmission components 20 within the target connection part protrude from their corresponding first connection surface 111 at approximately the same height.

[0088] For example, the mating seat 2110 includes a first mating surface 2111, which is an arc surface. The locking groove 2101 has a groove formed in the first mating surface 2111. Multiple force transmission members 20 are respectively located at different positions in the locking groove 2101 (e.g., Figure 10 (Different positions of the circumferential direction of the middle d-plane).

[0089] To facilitate the manufacturing process of multiple limiting springs 30, all limiting springs 30 are integrally molded.

[0090] This design not only facilitates the production of all the limiting springs 30, but also ensures the relative positional accuracy between all the limiting springs 30.

[0091] For example, all the limiting springs 30 can be integrally formed by injection molding, casting, stamping or machining.

[0092] Please continue to refer to this. Figures 1 to 8 In this embodiment, multiple connecting parts 11 and limiting components are provided and correspond one-to-one. All connecting parts 11 are used to surround the mating unit 2100 and are spaced apart.

[0093] By adopting the above scheme, the mating unit 2100 can be more effectively limited, and a stable connection between the lens body 2000 and the host 1000 can be achieved.

[0094] It should be noted that when multiple connecting parts 11 are provided, multiple first connecting surfaces 111 can be provided for some of the connecting parts 11, such as... Figure 6 As shown, the first connecting surface 111 of the other part of the connecting portion 11 may only have one, such as Figure 7 and Figure 8 As shown. When multiple connecting parts 11 are provided, multiple locking slots 2101 can also be provided.

[0095] It should also be noted that each limiting component may include multiple force transmission elements 20 and multiple limiting springs 30.

[0096] Optionally, the connector 10 includes a main body 12, and all connectors 11 are connected to the main body 12. The main body 12 and the connectors 11 can be integrally formed, such as by injection molding, casting, stamping, or machining. To reduce machining stress, the main body 12 and the connectors 11 can also be designed as a separate structure, that is, the connectors 11 can be individually attached to the main body 12 by screws to form a whole.

[0097] This design facilitates control over the relative positional accuracy between all connecting parts 11 and makes it easier to manufacture the connecting seat 10.

[0098] For example, the main body 12 and the connecting part 11 can be integrally formed by injection molding, casting, stamping or machining.

[0099] Optionally, the second connecting surface 112 of a portion of the connecting portion 11 is configured as a connecting plane adapted to the surface of the mating unit 2100, and the second connecting surface 112 of another portion of the connecting portion 11 is configured as a connecting arc surface adapted to the surface of the mating unit 2100.

[0100] This configuration allows for control of the relative position between the mating unit 2100 and the connecting unit 100 via the connecting plane and the connecting arc surface, thus preventing mistaken identification.

[0101] It is understandable that some of the connecting parts 11 can be set as square, while other parts of the connecting parts 11 can be set as arc-shaped.

[0102] It should be noted that the mating seat 2110 includes a first mating surface 2111 and a second mating surface 2112. The first mating surface 2111 is an arc surface and fits against the connecting arc surface. The second mating surface 2112 is a plane and fits against the connecting plane.

[0103] Alternatively, please refer to Figures 1 to 5 , Figure 9 and Figure 10The mating unit 2100 may include a mating seat 2110, and the portion of the force transmission member 20 protruding from the second opening may directly abut against the outer surface of the mating seat 2110. Alternatively, the mating seat 2110 may be provided with a locking groove 2101, and the portion of the force transmission member 20 protruding from the second opening may be located within the locking groove 2101 and abut against the inner wall surface of the locking groove 2101.

[0104] Please refer to the following for details. Figure 10 The locking groove 2101 has a limiting surface a, a front inclined surface b, a top surface c and a rear inclined surface d. The acute angle between the front inclined surface b and the horizontal direction is the tilt angle α, and the acute angle between the rear inclined surface and the horizontal direction is the tilt angle β. Since the tilt angle is proportional to the pulling resistance, the design requires the tilt angle α to be greater than the tilt angle β.

[0105] Please refer to Figures 1 to 8 Secondly, embodiments of this application provide a host 1000 for an endoscope system, the host 1000 including the connection unit 100 as described in the first aspect.

[0106] The endoscope system host 1000 provided in this application embodiment has a connecting part 11 for being disposed on one side of the mating unit 2100. The connecting part 11 has a first connecting surface 111 facing away from the mating unit 2100 and a second connecting surface 112 facing the mating unit 2100. The connecting part 11 is provided with a receiving hole, which has a first opening formed in the first connecting surface 111 and a second opening formed in the second connecting surface 112. The limiting component includes a force transmission member 20 and a limiting spring 30. The force transmission component 20 is movably disposed in the receiving hole. The force transmission component 20 protrudes from the first hole and the second hole. The limiting spring 30 is connected to the first connecting surface 111. Therefore, the part of the force transmission component 20 protruding from the first hole abuts against the limiting spring 30, so that the part of the force transmission component 20 protruding from the second hole abuts against the mating unit 2100, thereby effectively limiting the mating unit 2100 and achieving a stable connection between the mirror body 2000 and the host 1000.

[0107] Since the first opening of the receiving hole and the limiting spring 30 are both located on the first connecting surface 111, the structure of the connecting unit 100 can be made simpler, and the connecting part 11 can be easily processed. During assembly, it is easy to ensure the relative positional accuracy of the limiting spring 30 and the first opening. It is only necessary to connect the limiting spring 30 to the first connecting surface 111 and make the part of the force transmission member 20 protruding from the first opening abut against the limiting spring 30. The assembly process is simple and convenient.

[0108] It should be noted that the host 1000 can be a light source host or an integrated device that combines a light source host and an image processing device.

[0109] Please refer to Figures 1 to 8 Thirdly, embodiments of this application provide an endoscope system including a host 1000, a scope 2000, and a connection unit 100 as described in the first aspect. One of the host 1000 and the scope 2000 includes the connection unit 100, and the other of the host 1000 and the scope 2000 includes a mating unit 2100.

[0110] The endoscope system provided in this application embodiment has a connecting part 11 located on one side of the mating unit 2100. The connecting part 11 has a first connecting surface 111 facing away from the mating unit 2100 and a second connecting surface 112 facing the mating unit 2100. The connecting part 11 is provided with a receiving hole, which has a first opening formed on the first connecting surface 111 and a second opening formed on the second connecting surface 112. The limiting component includes a force transmission member 20 and a limiting spring 30. The force transmission member 20 is movably disposed in the receiving hole. The force transmission member 20 protrudes from both the first and second openings. The limiting spring 30 is connected to the first connecting surface 111. Therefore, the portion of the force transmission member 20 protruding from the first opening abuts against the limiting spring 30, so that the portion of the force transmission member 20 protruding from the second opening abuts against the mating unit 2100, thereby effectively limiting the mating unit 2100 and achieving a stable connection between the endoscope body 2000 and the main unit 1000.

[0111] Since the first opening of the receiving hole and the limiting spring 30 are both located on the first connecting surface 111, the structure of the connecting unit 100 can be made simpler, and the connecting part 11 can be easily processed. During assembly, it is easy to ensure the relative positional accuracy of the limiting spring 30 and the first opening. It is only necessary to connect the limiting spring 30 to the first connecting surface 111 and make the part of the force transmission member 20 protruding from the first opening abut against the limiting spring 30. The assembly process is simple and convenient.

[0112] It is understood that the scope 2000 may include a mating unit 2100, an operating unit 2300, and an insertion unit 2400, etc. The insertion unit 2400 is used to be inserted into the human body and has a COMS (Complementary Metal Oxide Semiconductor) device to obtain lesion information. The operating unit 2300 can operate the insertion unit 2400 to change direction. The flexible tube 2200 is used to conduct image electrical signals.

[0113] The host 1000 includes a connection unit 100, which can be plugged into and mated with the mating unit 2100.

[0114] Please refer to Figures 1 to 8 as well as Figure 11In order to restrict the rotation of the connecting unit 100 around the mating unit 2100 after the connecting unit 100 is inserted and mated with the mating unit 2100, the connecting unit 100 includes a first anti-rotation part 1001, and the mating unit 2100 includes a second anti-rotation part 2102. The first anti-rotation part 1001 and the second anti-rotation part 2102 are connected to restrict the rotation of the connecting unit 100 around the mating unit 2100.

[0115] By adopting the above scheme, after the connecting unit 100 and the mating unit 2100 are plugged in and mated, the connecting unit 100 can be restricted from rotating around the mating unit 2100, thereby preventing the mirror body 2000 from shaking during operation and improving its stability.

[0116] Optionally, the first anti-rotation part 1001 may be provided on the connecting seat 10, and the second anti-rotation part 2102 may be provided on the mating seat 2110.

[0117] Optionally, the first anti-rotation part 1001 is configured as an anti-rotation key, and the second anti-rotation part 2102 is configured as an anti-rotation groove; or, the first anti-rotation part 1001 is configured as an anti-rotation groove, and the second anti-rotation part 2102 is configured as an anti-rotation key.

[0118] This design simplifies the structure of both the first anti-rotation part 1001 and the second anti-rotation part 2102.

[0119] Understandably, when the connecting unit 100 is plugged into the mating unit 2100, the anti-rotation key enters the anti-rotation groove. The width of the anti-rotation groove can be slightly larger than the width of the anti-rotation key, and the amount of clearance on one side directly determines the degree of wobbling of the mirror body 2000.

[0120] Optionally, the side of the anti-rotation groove opening is chamfered (e), and the anti-rotation key can enter the anti-rotation groove through the chamfered (e).

[0121] With this setup, the chamfer e can be used to provide guidance, making it easier for the anti-rotation key to enter the anti-rotation groove.

[0122] For example, the chamfer e can be a bevel or a rounded corner.

[0123] Optionally, multiple first anti-rotation parts 1001 and multiple second anti-rotation parts 2102 are provided and correspond one-to-one. Multiple first anti-rotation parts 1001 are arranged around the mating unit 2100 and spaced apart.

[0124] This configuration better restricts the rotation of the connecting unit 100 around the mating unit 2100.

[0125] For example, two of each of the first anti-rotation part 1001 and the second anti-rotation part 2102 are provided. One of the first anti-rotation parts 1001 is provided corresponding to the connecting arc surface, and the other first anti-rotation part 1001 is provided corresponding to the connecting plane.

[0126] Optionally, the mating seat 2110 is connected to a guide step 2103, the shape of which can be adapted to the shape of the mating seat 2110. The guide step 2103 is also provided with a light guide rod 2104 and an air nozzle 2105. The mating seat 2110 is also connected to a communication component 2106.

[0127] The connector 10 is provided with a limiting block 1002, a receiving space 1003 and a socket 1004. When the connector 100 is plugged into the mating unit 2100, the limiting block 1002 abuts against the mating seat 2110, restricting the further movement of the mirror body 2000. The receiving space 1003 provides guidance for the guide step 2103. The communication component 2106 is housed in the socket 1004, and the host 1000 and the mirror body 2000 can exchange information such as images.

[0128] Please refer to Figures 1 to 15 The endoscope system provided in the above embodiments, when the host 1000 includes a connection unit 100 and the endoscope body 2000 includes a mating unit 2100, has the following connection process:

[0129] First, the front inclined surface b comes into contact with the four spherical force transmission components 20. At this time, under the action of the front inclined surface b, the force transmission components 20 move outward along the receiving hole, causing the limiting spring 30 to move in the same direction. The greater the moving distance, the greater the reaction force of the force transmission component 20 on the limiting spring 30, and the greater the supporting force of the fitting unit 2100 of the mirror body 2000 from the force transmission component 20.

[0130] like Figure 13 As shown, at this moment, during the further pushing of the mating unit 2100 in the direction of the arrow in the figure, the force transmission component 20 reaches the highest point of the front inclined surface b and contacts the top surface c. The resistance experienced by the mating unit 2100 mainly comes from the friction between the force transmission component 20 and the top surface c. The force transmission component 20 can be set as a smooth surface, and the friction can be ignored here.

[0131] like Figure 14 As shown, after the mirror body 2000 is further pushed in, when the force transmission component 20 contacts the rear inclined surface d, based on the principle of mechanics, the mating unit 2100 of the mirror body 2000 changes from being subjected to outward resistance from the steel ball to being subjected to inward thrust. The auxiliary mating unit 2100 enters the connection part 11 of the main unit 1000, as shown. Figure 15As shown, until the limiting block 1002 abuts against the mating seat 2110, the limiting spring 30 still maintains the applied force state, the force transmission member 20 fixes the mating unit 2100 in the connecting part 11, and the anti-rotation key further restricts the circumferential movement of the mating unit 2100 of the lens body 2000. At this time, the mating unit 2100 of the lens body 2000 is stably fixed in the connecting unit 100 of the host 1000. When it is necessary to pull out the mating unit 2100 of the lens body 2000, the process is the opposite of the aforementioned push-in process, which will not be described again.

[0132] Please refer to Figure 16 In other embodiments, the force transmission member 20 is spherical, the limiting spring 30 is provided with a centering hole, and the part of the force transmission member 20 protruding from the first opening is accommodated in the centering hole.

[0133] By adopting the above scheme, it is helpful for the spherical force transmission component 20 to remain centered when moving within the receiving hole, and to maintain the elastic stability of the limiting spring 30.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
