[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 upper or lower gastrointestinal endoscopes (hereinafter collectively referred to as endoscopes), the light transmitted from the main unit of the light source 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 tissues, and recording them through the image sensor at the back of the camera element while transmitting them to the main unit for further processing, and finally displaying them on the monitor for doctors to diagnose.

[0003] Once the endoscope body of the endoscope system is matched with the host, the host needs to provide the power required for normal operation of the endoscope body. The data signals collected by the endoscope body inside the human body also need to be transmitted to the host in real time for further analysis and processing. The control signals of the host also need to be transmitted to the endoscope body in real time to enable it to perform specific diagnostic functions. Therefore, a connection unit is required to achieve a stable connection between the endoscope body and the host, ensuring stable power supply and signal transmission between the host and the endoscope body.

The mating unit is equipped with a wireless power supply receiving module and an endoscope-side wireless communication module. The connection unit includes:

[0006] The connector includes a connector, a wireless power supply transmitter module, and a host-side wireless communication module. The connector has a first connecting surface and a second connecting surface facing away from each other. The connector is provided with a receiving hole. The receiving hole has a first opening formed on the first connecting surface and a second opening formed on the second connecting surface. The position of the wireless power supply transmitter module relative to the receiving hole and the position of the host-side wireless communication module relative to the receiving hole are both fixed.

[0007] The limiting component includes a force-transmitting element and a limiting spring. The force-transmitting element is movably disposed within the receiving hole.

[0012] In some embodiments, the connector includes a main body connected to the connecting portion, the main body having a first insertion portion, and the mating unit having a second insertion portion, wherein the first insertion portion is used to insert into the second insertion portion when the connecting unit and the mating unit are assembled.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] To illustrate the technical solution of this application, the following description is provided in conjunction with specific accompanying drawings and embodiments.

[0054] For upper or lower gastrointestinal endoscopes (hereinafter collectively referred to as endoscopes), the light transmitted from the main unit of the light source 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 tissues, and recording them through the image sensor at the back of the camera element while transmitting them to the main unit for further processing, and finally displaying them on the monitor for doctors to diagnose.

[0055] Once the endoscope body of the endoscope system is matched with the host, the host needs to provide the power required for normal operation of the endoscope body. The data signals collected by the endoscope body inside the human body also need to be transmitted to the host in real time for further analysis and processing. The control signals of the host also need to be transmitted to the endoscope body in real time to enable it to perform specific diagnostic functions. Therefore, a connection unit is required to achieve a stable connection between the endoscope body and the host, ensuring stable power supply and signal transmission between the host and the endoscope body.

[0056] In view of this, this application provides a connection unit for an endoscope system, a host unit for an endoscope system, and an endoscope system. Since the limiting spring has a connected mounting structure and a cantilever structure, and the mounting structure is connected to the connection part, and the cantilever structure includes a supporting part, the portion of the force transmission member protruding from the first orifice can stably abut against the supporting part. Thus, when the connection unit and the mating unit are assembled, the portion of the force transmission member protruding from the second orifice can stably abut against the mating unit. The wireless power transmission module and the wireless power receiving module are aligned, and the host-side wireless communication module and the endoscope-side wireless communication module are aligned, thereby achieving a stable connection between the endoscope and the host, and ensuring stable power supply and signal transmission between the host and the endoscope.

[0057] Please refer to Figures 1 to 6 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. The host 1000 includes the connection unit 100, and the scope 2000 includes a mating unit 2100. The mating unit 2100 is provided with a wireless power supply receiving module 2106 and a scope-side wireless communication module 2107.

[0058] The wireless power supply receiver module 2106 may include a coil, etc. The mirror-side wireless communication module 2107 may include a laser communication module, etc.

[0059] The connection unit 100 includes a connection base 10 and a limiting component.

[0060] The connector 10 includes a connector 11, a wireless power supply transmitter module 1004, and a host-side wireless communication module 1005. The connector 11 has a first connecting surface 111 and a second connecting surface 112 facing away from each other. The connector 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 positions of the wireless power supply transmitter module 1004 and the host-side wireless communication module 1005 relative to the receiving hole are both fixed.

[0061] One or more connecting parts 11 may be provided. When multiple connecting parts 11 are provided, they may be arranged around the mating unit 2100 and spaced apart. Multiple receiving holes may be provided. The wireless power supply transmitting module 1004 may include coils, etc. The host-side wireless communication module 1005 may include laser communication modules, etc.

[0062] Please refer to this as well. Figures 7 to 9The 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 the first opening and the second opening. The limiting spring 30 has a mounting structure 31 and a cantilever structure 32 connected to each other. The mounting structure 31 is connected to the connecting part 11. The cantilever structure 32 includes a supporting part 321. The portion of the force transmission member 20 protruding from the first opening abuts against the supporting part 321, 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. The wireless power supply transmitting module 1004 is aligned with the wireless power supply receiving module 2106, and the host-side wireless communication module 1005 is aligned with the mirror-side wireless communication module 2107.

[0063] 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. The mounting structure 31 and the cantilever structure 32 can be integrally formed by injection molding, casting, stamping, or machining. For example, the limiting spring 30 has a simple structure and can be manufactured by one-time stamping.

[0064] The limiting spring 30 can be a flexible metal spring or a flexible plastic spring, etc. The mounting structure 31 and the connecting part 11 can be connected by means of bonding, welding, screw connection or bolt connection, such as by pin and screw connection. Under the action of the limiting spring 30's own elastic force, the part of the force transmission member 20 protruding from the first orifice is kept in a resisting state with the abutting part 321, and the part of the force transmission member 20 protruding from the second orifice is kept in a resisting state with the mating unit 2100.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] The wireless power supply transmitter module 1004 and the wireless power supply receiver module 2106 do not necessarily need to be perfectly aligned; there can be a certain tolerance between them. The key is that the host 1000 can supply power to the mirror 2000 through the wireless power supply transmitter module 1004 and the wireless power supply receiver module 2106. Similarly, the host-side wireless communication module 1005 and the mirror-side wireless communication module 2107 do not necessarily need to be perfectly aligned; there can be a certain tolerance between them. The key is that the host 1000 and the mirror 2000 can transmit signals through the host-side wireless communication module 1005 and the mirror-side wireless communication module 2107.

[0069] As can be seen from the above, the connection unit 100 provided in this application embodiment has a mounting structure 31 and a cantilever structure 32 connected to the limiting spring 30. The mounting structure 31 is connected to the connection part 11, and the cantilever structure 32 includes a supporting part 321. Therefore, the part of the force transmission member 20 protruding from the first orifice can stably support the supporting part 321. Thus, when the connection unit 100 and the mating unit 2100 are assembled, the part of the force transmission member 20 protruding from the second orifice can stably support the mating unit 2100. The wireless power supply transmitting module 1004 and the wireless power supply receiving module 2106 are aligned, and the host-side wireless communication module 1005 and the mirror-side wireless communication module 2107 are aligned. This achieves a stable connection between the mirror 2000 and the host 1000, ensuring stable power supply and signal transmission between the host 1000 and the mirror 2000.

[0070] 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.

[0071] It should be noted that after the endoscope 2000 is matched with the host 1000, the host 1000 needs to provide the endoscope 2000 with the power required for normal operation. The data signals collected by the endoscope 2000 inside the human body also need to be transmitted to the host 1000 in real time for further analysis and processing. The control signals of the host 1000 also need to be transmitted to the endoscope 2000 in real time to enable it to perform specific diagnostic functions. This transmission of power and signals is conventionally done by connecting via cables, but this requires a high level of electromagnetic interference resistance from the system and is not flexible enough.

[0072] Wireless power supply and wireless communication technologies have high requirements for the quality of connection between the supply and demand sides. At the same time, there are multiple mirrors 2000 that can be matched with the host 1000, and there are frequent replacements between the mirrors 2000 and the host 1000. In addition, during use, the connection part 11 of the existing mirrors 2000 will also experience normal shaking.

[0073] The connection unit 100 and the cooperation unit 2100 provided in this embodiment enable the host 1000 to provide power to the endoscope 2000 wirelessly, and realize information interaction between the host 1000 and the endoscope 2000 through wireless communication. Finally, the limiting spring 30 and the force transmission component 20 provide a holding force for the endoscope 2000 inserted into the host 1000 during the docking process. By adopting a specific structure and hardness of the limiting spring 30, the endoscope 2000 can be prevented from falling off during use, ensuring communication quality and normal power supply, while also providing a light and easy way to pull it out after use. Thus, under the premise of frequent docking between the endoscope 2000 and the light source host 1000, the endoscope 2000 can ensure stable power supply and communication quality during docking with the host 1000, while making its structure simple and highly reliable. It can ensure that no major medical accidents such as the endoscope 2000 falling off and causing communication loss or even power failure will occur during frequent use.

[0074] Optionally, the distance between the mounting structure 31 and the supporting part 321 is L, the width of the mounting structure 31 is M, the width of the supporting part 321 is N, 30mm≤L≤40mm, 1mm≤M≤10mm, and 1mm≤N≤10mm.

[0075] This design allows the limiting spring 30 to have better mechanical properties, ensuring that the portion of the force transmission member 20 protruding from the first opening is stably supported by the supporting portion 321.

[0076] In this embodiment, the width of the cantilever structure 32 gradually decreases in the direction from the mounting structure 31 to the supporting part 321, at which point M>N.

[0077] By adopting the above solution, the mechanical properties of the limiting spring 30 can be improved, thereby ensuring that the part of the force transmission member 20 protruding from the first orifice and the supporting part 321 support each other more stably.

[0078] It should be noted that since the width of the cantilever structure 32 gradually decreases from the mounting structure 31 to the supporting part 321, the deflection of the cantilever structure 32 can be reduced, thereby reducing the installation stress near the mounting structure 31, improving the stability and safety of the limiting spring 30, and enabling the limiting spring 30 to have better mechanical properties, ensuring that the part of the force transmission member 20 protruding from the first orifice is stably supported by the supporting part 321.

[0079] Optionally, the inclination angle of the sidewall of the cantilever structure 32 relative to the sidewall of the mounting structure 31 is θ, where 0°≤θ≤10°.

[0080] This design allows for better mechanical properties of the limiting spring 30, ensuring that the portion of the force transmission member 20 protruding from the first opening is stably supported by the supporting portion 321.

[0081] For example, L can be 30mm, 32mm, 35mm, 38mm, or 40mm, etc. M can be 1mm, 3mm, 35mm, 7mm, or 10mm, etc. M can be 1mm, 3mm, 35mm, 7mm, 9mm, or 10mm, etc. θ can be 0°, 1°, 3°, 5°, 7°, 9°, or 10°, etc.

[0082] It should be noted that the distance L between the mounting structure 31 and the supporting part 321 is the closest distance between the mounting structure 31 and the supporting part 321, which can be the distance between the root of the cantilever structure 32 and the mounting structure 31 and the supporting part 321. When the width of the cantilever structure 32 gradually decreases from the mounting structure 31 to the supporting part 321, 0°<θ≤10°.

[0083] The connecting portion 11 has a third connecting surface 113, the orientation of which is the same as that of the first connecting surface 111. The mounting structure 31 is connected to the third connecting surface 113. The direction from the second opening to the first opening is the first direction. The third connecting surface 113 protrudes from the first connecting surface 111 in the first direction, and the mounting structure 31 protrudes from the supporting portion 321 in the first direction. The first direction can be... Figure 4 The direction indicated by the middle arrow T.

[0084] By adopting the above solution, a preload force can be provided to the force transmission member 20 in the non-working state, ensuring that when the part of the force transmission member 20 protruding from the first orifice abuts against the supporting part 321, the part of the force transmission member 20 protruding from the second orifice abuts against the supporting unit 2100 when the connecting unit 100 and the mating unit 2100 are assembled.

[0085] Optionally, the third connecting surface 113 is arranged parallel to the first connecting surface 111, and the distance between the mounting structure 31 and the supporting part 321 in the first direction is greater than the distance between the third connecting surface 113 and the first connecting surface 111 in the first direction.

[0086] This configuration allows for a greater preload force to be provided to the force transmission member 20 when it is not in operation, ensuring that when the portion of the force transmission member 20 protruding from the first orifice abuts against the supporting portion 321, the portion of the force transmission member 20 protruding from the second orifice abuts against the supporting unit 2100 when the connecting unit 100 and the mating unit 2100 are assembled.

[0087] Please refer to this as well. Figures 10 to 16 In this embodiment, the connector 10 includes a main body 12 connected to the connector 11. The main body 12 is provided with a first insertion part 1003, and the mating unit 2100 is provided with a second insertion part 2103. The first insertion part 1003 is used to insert into the second insertion part 2103 when the connector 100 and the mating unit 2100 are assembled.

[0088] By adopting the above solution, the stability of the connection between the connecting unit 100 and the mating unit 2100 can be further improved when they are assembled.

[0089] It should be noted that the first insertion portion 1003 may be a recessed portion, and the second insertion portion 2103 may be a protruding portion. Alternatively, the first insertion portion 1003 may be a protruding portion, and the second insertion portion 2103 may be a recessed portion.

[0090] Optionally, the first plug-in portion 1003 is configured as a recessed portion, and the wireless power supply transmitting module 1004 is configured correspondingly to the inner wall of the recessed portion; the second plug-in portion 2103 is configured as a protruding portion, and the wireless power supply receiving module 2106 is configured correspondingly to the outer surface of the protruding portion.

[0091] With this configuration, when the first connector 1003 and the second connector 2103 are connected together, the wireless power supply transmitter module 1004 and the wireless power supply receiver module 2106 can cooperate to achieve a wireless connection between the host 1000 and the mirror body 2000.

[0092] Optionally, the main body 12 and the connecting part 11 are integrally formed.

[0093] This design makes it easier to manufacture the connector 10 and also gives the connector 10 a better sense of unity.

[0094] It should be noted that the main body 12 and the connecting part 11 can be integrally formed by injection molding, casting, stamping or machining.

[0095] Please refer to Figures 1 to 11 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.

[0096] Therefore, the number of connecting parts 11 is one or more, and the target connecting part is any one of the connecting parts 11;

[0097] For the target connection part, its first connection surface 111 is set as a plane, and multiple first connection surfaces 111 are provided and arranged in parallel. The distances between two first connection surfaces 111 and the mating unit 2100 are not equal. The second connection 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. The axis of the receiving hole is perpendicular to the first connection surface 111.

[0098] By adopting the above scheme, not only can the multiple force transmission components 20 in the target connection part 11 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 11 are perpendicular to the first connection surface 111, thereby making the processing of the receiving holes more convenient.

[0099] It is understandable that the different force transmission components 20 within the target connection part protrude from their corresponding first connection surfaces 111 at approximately the same height. The height difference between the two first connection surfaces 111, which are unequal in distance from the mating unit 2100, is d.

[0100] It should be noted that since the distance between the mounting structure 31 and the supporting part 321 is L, and 30mm≤L≤40mm, the length of the cantilever structure 32 can be made longer, avoiding the risk that the movement of the cantilever structure 32 of a single limiting spring 30 will affect the cantilever structure 32 of its adjacent limiting spring 30, thus improving the locking stability.

[0101] 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 11 (Different positions of the circumferential direction of the middle d-plane).

[0102] To facilitate the manufacturing process of multiple limiting springs 30, all limiting springs 30 are integrally molded.

[0103] 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.

[0104] For example, all the limiting springs 30 can be integrally formed by injection molding, casting, stamping or machining.

[0105] Please refer to Figures 1 to 9 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.

[0106] 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.

[0107] 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 7 As shown, the first connecting surface 111 of the other part of the connecting portion 11 may only have one, such as Figure 8 and Figure 9 As shown. When multiple connecting parts 11 are provided, multiple locking slots 2101 can also be provided. All connecting parts 11 are connected to the main body 12.

[0108] It should also be noted that each limiting component may include multiple force transmission elements 20 and multiple limiting springs 30.

[0109] 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.

[0110] 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.

[0111] 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.

[0112] 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.

[0113] Alternatively, please refer to Figures 1 to 6 , Figure 10 and Figure 11The 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.

[0114] Please refer to the following for details. Figure 11 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 d 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.

[0115] In some other embodiments, the force transmission member 20 is spherical, and the limiting spring 30 is provided with a centering hole or a centering groove, and the part of the force transmission member 20 protruding from the first opening is accommodated in the centering hole.

[0116] 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.

[0117] Please refer to Figures 1 to 9 Secondly, embodiments of this application provide a host for an endoscope system, the host 1000 including the connection unit 100 as described in the first aspect.

[0118] The endoscope system 1000 provided in this application embodiment has a limiting spring 30 with a connected mounting structure 31 and a cantilever structure 32. The mounting structure 31 is connected to the connecting part 11, and the cantilever structure 32 includes a supporting part 321. Therefore, the part of the force transmission member 20 protruding from the first orifice can stably abut against the supporting part 321. Thus, when the connecting unit 100 and the mating unit 2100 are assembled, the part of the force transmission member 20 protruding from the second orifice can stably abut against the mating unit 2100. The wireless power supply transmitting module 1004 is aligned with the wireless power supply receiving module 2106, and the host-side wireless communication module 1005 is aligned with the endoscope-side wireless communication module 2107. This achieves a stable connection between the endoscope 2000 and the host 1000, ensuring stable power supply and signal transmission between the host 1000 and the endoscope 2000.

[0119] 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.

[0120] Please refer to Figures 1 to 9Thirdly, 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. The host 1000 includes the connection unit 100, and the scope 2000 includes a mating unit 2100.

[0121] The endoscope system provided in this application embodiment has a limiting spring 30 with a connected mounting structure 31 and a cantilever structure 32. The mounting structure 31 is connected to the connecting part 11, and the cantilever structure 32 includes a supporting part 321. Therefore, the part of the force transmission member 20 protruding from the first orifice can stably support the supporting part 321. Thus, when the connecting unit 100 and the mating unit 2100 are assembled, the part of the force transmission member 20 protruding from the second orifice can stably support the mating unit 2100. The wireless power supply transmitting module 1004 is aligned with the wireless power supply receiving module 2106, and the host-side wireless communication module 1005 is aligned with the endoscope-side wireless communication module 2107. This achieves a stable connection between the endoscope 2000 and the host 1000, ensuring stable power supply and signal transmission between the host 1000 and the endoscope 2000.

[0122] 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.

[0123] The host 1000 includes a connection unit 100, which can be plugged into and mated with the mating unit 2100.

[0124] Please refer to Figures 1 to 9 as well as Figure 12 In 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.

[0125] 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, improving its stability, and ensuring stable power supply and communication.

[0126] 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.

[0127] 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.

[0128] This design simplifies the structure of both the first anti-rotation part 1001 and the second anti-rotation part 2102.

[0129] 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.

[0130] 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).

[0131] 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.

[0132] Optionally, the bottom of the anti-rotation key can also be chamfered, and the two sides of the anti-rotation groove opening are chamfered e to guide the anti-rotation key from the side. The chamfer at the bottom of the anti-rotation key guides the anti-rotation key from the bottom, so that the anti-rotation key can enter the anti-rotation groove more easily.

[0133] For example, the chamfer 'e' can be either a bevel or a fillet. The chamfer at the bottom of the anti-rotation key can be either a bevel or a fillet.

[0134] 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.

[0135] This configuration better restricts the rotation of the connecting unit 100 around the mating unit 2100.

[0136] 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.

[0137] Optionally, the mating seat 2110 is also provided with a light guide rod 2104 and an air nozzle 2105, etc. The connecting seat 10 is provided with a limiting block 1002. When the connecting unit 100 and the mating unit 2100 are plugged in, the limiting block 1002 abuts against the mating seat 2110 to restrict the further movement of the mirror body 2000. The first plug-in part 1003 and the second plug-in part 2103 are plugged together to provide guidance. The wireless power supply transmitting module 1004 is aligned with the wireless power supply receiving module 2106, and the host side wireless communication module 1005 is aligned with the mirror body side wireless communication module 2107. The host 1000 uses wireless means to realize power supply and signal transmission with the mirror body 2000.

[0138] Please refer to Figures 1 to 16 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:

[0139] First, the first insertion part 1003 and the second insertion part 2103 are inserted together. The front inclined surface b first contacts the four spherical force transmission members 20. At this time, under the action of the front inclined surface b, the force transmission members 20 move outward along the receiving hole, so that the limiting spring 30 moves in the same direction. The greater the moving distance, the greater the reaction force of the force transmission members 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 members 20.

[0140] like Figure 14 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.

[0141] like Figure 15 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 16As 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 component 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. The wireless power supply transmitting module 1004 is aligned with the wireless power supply receiving module 2106, and the host-side wireless communication module 1005 is aligned with the lens-side wireless communication module 2107. The host 1000 uses wireless means to realize power supply and signal transmission with the lens body 2000. When it is necessary to pull out the mating unit 2100 of the lens body 2000, the process is the reverse of the aforementioned push-in process, which will not be described again.

[0142] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. 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. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
