Description

Technical Field

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

[0002] As a core device for medical diagnosis and treatment, the stable connection between the endoscope and the main unit is crucial. The endoscope needs to be connected to the main unit through a light guide.

[0003] In related technologies, the light guide and the host interface are typically electrically connected via multiple pins. However, due to structural and manufacturing errors, the compression of each pin is inconsistent, leading to unstable connections and abnormal signal transmission. Utility Model Content

[0004] This application provides an interface structure for an endoscope host, an endoscope host, and an endoscope, which can improve the connection stability between the light guide and the host interface structure, thereby improving the stability of signal transmission.

[0005] The first aspect of this application provides an interface structure for an endoscope host, including:

[0006] An interface ring having a mounting cavity, the mounting cavity having multiple openings along the circumference of the interface ring, and the interface ring having a limiting portion corresponding to each opening;

[0007] Multiple pins are disposed in the mounting cavity, each pin having a contact point extending from the opening, and the pins are adapted to deform and be confined on the limiting portion.

[0008] According to the interface structure described in the first aspect of this application, the pins can be housed in the mounting cavity, and a portion of the pin can extend from the opening to form a contact point, which can contact the contact portion on the light guide. Because the pins can deform, they can change from a natural state to a deformed state. The natural state corresponds to the aforementioned first state, and the deformed state corresponds to the aforementioned second state. When each pin changes from its natural state to its deformed state, each pin can accumulate internal stress. The limiting portion then restricts the pins to the deformed state. This internal stress drives the contact points of each pin to protrude from the opening to a uniform degree, ensuring that when the light guide is inserted into the interface ring, each contact point can contact the contact portion to the same degree. This ensures consistency in the contact points of each pin, guaranteeing that each pin has the same amount of compression, thereby improving the connection stability between the light guide and the host interface structure, and thus improving the stability of signal transmission.

[0009] In one possible implementation, the pin includes a main body segment and a bent segment connected to the main body segment, the bent segment protruding from the opening, and the portion of the bent segment with the largest radius of curvature forming the contact point.

[0010] In one possible implementation, the pin further includes a tail section, the bent section being connected between the body section and the tail section, the tail section being adapted to be confined in the limiting portion.

[0011] In one possible implementation, the tail section is concealed within the mounting cavity, and the limiting portion is also concealed within the mounting cavity.

[0012] In one possible implementation, the pin is obliquely disposed in the interface ring at an angle to the axial direction of the interface ring.

[0013] In one possible implementation, the included angle is 2° to 5°.

[0014] In one possible implementation, the pin has a first end and a second end, the second end being close to the opening, the first end being away from the axis of the interface ring, the second end being close to the axis of the interface ring, and the second end being adapted to be confined to the limiting portion, the distance between the limiting portion and the axis being greater than the distance between the second end and the axis.

[0015] In one possible implementation, the interface ring includes a first ring segment and a second ring segment, the second ring segment being sleeved on one end of the first ring segment, and the mounting cavity being formed between the first ring segment and the second ring segment, or the second ring segment forming the mounting cavity.

[0016] In one possible implementation, the second ring segment includes an outer wall, an inner wall, and an end wall connecting the outer wall and the inner wall, the inner wall, the outer wall, and the end wall forming the mounting cavity, the inner wall having the opening, and the peripheral portion of the inner wall corresponding to the opening forming the limiting portion.

[0017] In one possible implementation, the outer wall of the first ring segment is provided with a support portion, the support portion including an inclined support surface, and the pin is attached to the support surface.

[0018] In one possible implementation, the distance between the support portion and the axis of the interface ring is less than the distance between the limiting portion and the axis of the interface ring.

[0019] In one possible implementation, the pin includes a copper substrate and a first plating layer, a second plating layer, and a third plating layer sequentially disposed on the surface of the copper substrate. The first plating layer is made of nickel, the second plating layer is made of palladium-nickel, and the third plating layer is made of gold.

[0020] A second aspect of this application provides an endoscope host, including the interface structure described in the first aspect.

[0021] A third aspect of this application provides an endoscope, including a light guide and the endoscope host described in the second aspect. The light guide is adapted to be inserted into the interface ring. The light guide has a plurality of contact portions arranged circumferentially thereon, and the plurality of contact portions are configured to correspond to contact points of a plurality of pins.

[0036] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. 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

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0038] An endoscope is a mechanical device with an image sensor, optical lens, and optical illumination. It allows for the observation, diagnosis, and treatment of organs such as the intestines and stomach. To assist the optical lens in capturing images, endoscopes typically also have interfaces for supplying water, air, or a mixture of both, as well as suction interfaces for drawing water or air. In short, an endoscope is a structure that integrates multiple functions.

[0039] As a core device for medical diagnosis and treatment, the stable connection between the endoscope and the main unit is crucial. The endoscope needs to be connected to the main unit through a light guide. The endoscope, the main unit, and the light guide are the three important components of an endoscope.

[0040] In related technologies, the host interface has multiple pins arranged circumferentially, typically in an upright position, meaning the pins extend parallel to the axis of the host interface. The light guide has contact parts arranged circumferentially to engage with these pins. Electrical connection between the light guide and the host is achieved through this contact connection. The contact parts and pins are usually in a compression relationship, causing a certain degree of compression on the pins. However, due to structural errors, manufacturing errors, and component deformation, the shapes of the pins are inconsistent, and their distances from the host interface axis are not perfectly uniform. This makes it difficult for each pin to contact the contact parts in the same way. After assembling the light guide onto the host interface, the varying compression forces between the contact parts and pins result in inconsistent compression levels, leading to unstable connections and abnormal signal transmission. Furthermore, when the light guide is inserted into the host interface, friction is generated between the contact parts and pins. This friction may cause the pins to be lifted and bent, leading to signal connection failures and even damage to the host.

[0041] Based on the above situation and problems, this application provides an interface structure for an endoscope host. The interface structure of the endoscope host reconfigures the pins and the surrounding structure of the pins, so that the parts of each pin that need to contact the contact part are consistent, thereby improving the connection stability between the light guide part and the host interface structure, and thus improving the stability of signal transmission.

[0042] Therefore, the pins in the interface structure of the endoscope host in this embodiment can change state to ensure the uniformity of the contact points of each pin. Specifically, the pin has a first state and a second state, where the first and second states result in different positions for the pin. The first state is the natural state of the pin. When the pin switches from the first state to the second state, the position of the pin changes and breaks its natural state, causing the pin to be subjected to internal stress. By restricting the pin to the second state, this internal stress can maintain the consistency of the contact points of each pin. To keep the pin in the second state, the interface structure of the endoscope host in this embodiment is also equipped with a limiting part. This limiting part can form a compression with the pin. By reasonably setting the structure and position of the limiting part, it can prevent the light guide part from acting on the end of the pin when it is inserted into the interface structure of the endoscope host, thereby preventing the pin from bending and ensuring the stability of signal transmission, and preventing damage to the host.

[0043] Figure 1 A schematic diagram of the connection of an endoscope according to an embodiment of this application is shown; Figure 2 A schematic diagram of the structure of a light guide 10 provided according to an embodiment of this application is shown.

[0044] In the embodiments of this application, please refer to Figure 1 The endoscope includes a light guide 10 and an endoscope host 20. The endoscope host 20 is equipped with an interface structure 21, into which the light guide 10 can be inserted.

[0045] The light guide portion 10 has multiple contact portions 11 arranged along its circumference. These contact portions 11 can be elastic structures such as contact springs, or they can be rigid conductors. (See reference...) Figure 2 Multiple contact portions 11 are evenly arranged circumferentially on the outer periphery of the light guide portion 10.

[0046] The light guide portion 10 is adapted to be inserted into the interface ring 100 in the interface structure 21. The interface ring 100 is a component of the interface structure 21. A plurality of pins 200 are provided in the interface ring 100, and each pin 200 has a contact point 201 exposed from the interface ring 100. The plurality of contact portions 11 are configured to be able to contact the contact points 201 of the plurality of pins 200 respectively.

[0047] As can be seen from the description of the interface structure 21 in the following embodiments, the arrangement of multiple pins 200 in the interface structure 21 can make the contact points 201 of each pin 200 consistent, so that the multiple pins 200 have the same amount of compression after being squeezed by the contact part 11, thereby improving the connection stability between the light guide part 10 and the host interface structure 21, and thus improving the stability of signal transmission.

[0048] This application embodiment does not describe other structures of the light guide 10 in detail. For example, the light guide 10 can also be configured with various connectors, etc., and the light guide 10 can also be configured with light guide components for transmitting light and imaging fiber optic components for imaging, etc.

[0049] The embodiments of this application will not go into detail about other structures of the endoscope host 20. In addition to the interface structure 21 mentioned above, the endoscope host 20 in the embodiments of this application also includes a housing, a signal processor, an image processor and other structures.

[0050] Other structures of the light guide 10 and the endoscope host 20 described above can be understood with reference to related technologies.

[0051] Figure 3 A schematic diagram of an interface structure 21 provided according to an embodiment of this application is shown; Figure 4 This diagram shows a structural schematic of an interface structure 21 provided according to an embodiment of the present application from another angle.

[0052] In the embodiments of this application, please refer to Figure 3 and Figure 4The interface structure 21 includes an interface ring 100 and multiple pins 200.

[0053] The interface ring 100 is a ring structure, but this does not mean that the cross-section of the interface ring 100 must be circular. The cross-section here refers to the cross-section perpendicular to the axial direction of the interface ring 100. It can be understood that in some cases, the cross-section of the interface ring 100 can be circular, elliptical, or even polygonal.

[0054] The interface ring 100 has a hollow structure and a mounting channel 101, into which the light guide 10 can be inserted. In addition, the interface ring 100 also has a mounting cavity 102, which surrounds the mounting channel 101. The mounting cavity 102 has a plurality of openings 103 along the circumference of the interface ring 100, and the interface ring 100 has a limiting part 104 corresponding to each opening 103.

[0055] It is understandable that, since the mounting cavity 102 is provided with an opening 103, the opening 103 can connect the mounting channel 101 and the mounting cavity 102. Therefore, after the light guide 10 is inserted into the mounting channel 101, the light guide 10 can make contact with the pin 200 located in the mounting cavity 102.

[0056] The embodiments of this application do not impose any particular restrictions on the number and specific shape of the openings 103. The openings 103 may be elongated openings 103 or openings 103 of other shapes.

[0057] It should be noted that the provision of a limiting part 104 for each opening 103 in the interface ring 100 does not mean that the number of limiting parts 104 is the same as the number of openings 103. In some embodiments, the number of the two can be the same, and in other embodiments, the number of limiting parts 104 can be less than the number of openings 103. For example, the number of openings 103 can be an integer multiple of the number of limiting parts 104.

[0058] Multiple pins 200 are correspondingly disposed in the mounting cavity 102. Each pin 200 has a contact point 201 extending from the opening 103. The pins 200 are adapted to deform and be confined on the limiting portion 104.

[0059] This can be understood as follows: the pin 200 can be housed in the mounting cavity 102, and a part of the pin 200 can extend from the opening 103 to form a contact point 201, which can contact the contact part 11 on the light guide part 10. Because the pins 200 can deform, they can change from a natural state to a deformed state. The natural state corresponds to the first state mentioned above, and the deformed state corresponds to the second state mentioned above. When each pin 200 changes from its natural state to its deformed state, each pin 200 can accumulate internal stress. The limiting part 104 then restricts the pin 200 to the deformed state. This internal stress can drive the contact points 201 of each pin 200 to be exposed at the opening 103 to a consistent degree. This ensures that when the light guide part 10 is inserted into the interface ring 100, each contact point 201 can contact the contact part 11 to the same degree. This ensures that the parts of each pin 200 that need to contact the contact part 11 are consistent, thereby ensuring that each pin 200 has the same amount of compression. This improves the connection stability between the light guide part 10 and the host interface structure 21, thereby improving the stability of signal transmission.

[0060] It should be noted that the aforementioned internal stress preferably causes the contact point 201 to extend further out of the opening 103. In other words, when the pin 200 changes from its natural state to its shaped state, the length of the contact point 201 extending out of the opening 103 will increase. As a result, when the light guide 10 is inserted into the interface ring 100, a more reliable connection can be formed between the contact part 11 and the contact point 201.

[0061] Of course, in other embodiments, the effect of internal stress can also drive the contact point 201 to be more recessed into the opening 103. In other words, when the pin 200 changes from its natural state to its shaped state, the length of the contact point 201 extending from the opening 103 will be smaller. However, it is necessary to ensure that the contact point 201 always extends from the opening 103, thereby ensuring the consistency of each contact point 201.

[0062] Figure 5 A cross-sectional view of a pin 200 in its natural state is shown in an interface structure 21 provided according to an embodiment of this application; Figure 6 It shows Figure 5 A magnified view of a portion of the image; Figure 7 A cross-sectional view of a pin 200 in a deformed state in an interface structure 21 provided according to an embodiment of this application is shown. Figure 8 It shows Figure 7 A magnified view of a portion of the image.

[0063] In some embodiments, please refer to Figure 5The pin 200 includes a main body segment 210 and a bent segment 220 connected to the main body segment 210. The bent segment 220 protrudes from the opening 103, and the part of the bent segment 220 with the largest radius of curvature forms the contact point 201.

[0064] The main body segment 210 can be connected and fixed to the interface ring 100. For example, in the following embodiment, the main body segment 210 can be connected to the support portion 130 of the interface ring 100. Of course, in other embodiments, the main body segment 210 can also be fixedly connected to other parts of the interface ring 100. For example, if the interface ring 100 has a slot, the main body segment 210 can be accommodated in the slot.

[0065] The main body segment 210 can be designed as a straight structure to ensure the overall axial strength of the pin 200. The length of the main body segment 210 can be set according to requirements.

[0066] The bent segment 220 can be constructed as an arc shape. For example, the bent segment 220 can be an arc at one end of a standard circle. In this case, the point on the bent segment 220 that is farthest from the main segment 210 forms the aforementioned contact point 201. Thus, the radii of curvature of different parts of the bent segment 220 are different, with the part having the largest radius of curvature forming the contact point 201.

[0067] In this embodiment, the bend 220 is an arc-shaped structure, which facilitates the installation of the light guide 10 and reduces the obstruction of the bend 220 to the contact part 11, allowing the light guide 10 to be inserted into the interface ring 100 more smoothly.

[0068] It should be understood that in other embodiments, the bent segment 220 may also be configured in other structures, such as wavy.

[0069] In some embodiments, please refer to Figure 6 The insert 200 also includes a tail section 230, a bent section 220 connected between the main body section 210 and the tail section 230, and the tail section 230 is adapted to be confined in the limiting portion 104.

[0070] Looking from the axial direction of the interface ring 100 toward the direction closer to the light guide 10, the various parts of the pin 200 are, in order, the main body section 210, the bent section 220, and the tail section 230. The main body section 210 mainly serves to connect and fix, the bent section 220 mainly forms the contact point 201, and the tail section 230 serves to cooperate with the limiting part 104, thereby restricting the pin 200 to a deformed state.

[0071] This application embodiment does not limit the specific structure of the limiting part 104. The limiting part 104 can be formed from a portion of the interface ring 100, and it can also be connected to the interface ring 100 via mechanical connection or other means. It is understood that, depending on the different structures of the tail section 230, the limiting part 104 can have different shapes. For example, in… Figure 6 In the example shown, the tail segment 230 is a straight structure that is shorter in length than the main body segment 210. To accommodate the tail segment 230, the limiting part 104 can be a support platform, which can be part of the inner wall 122 of the interface ring 100 in the following embodiments. Alternatively, the tail segment 230 can also be designed as a hook, in which case the limiting part 104 can be a hanging ring or a hanging hole, etc.

[0072] It should be understood that the above description of the pin 200 in terms of its parts is intended to indicate that each part of the pin 200 can perform different functions, and does not mean that the pin 200 is a split structure. In some embodiments, the pin 200 can be integrally formed.

[0073] In some embodiments, the tail section 230 is hidden in the mounting cavity 102, and the limiting portion 104 is also hidden in the mounting cavity 102.

[0074] Therefore, the cooperation between the tail section 230 and the limiting part 104 can avoid interfering with the opening 103 and its surroundings, and can ensure that the contact point 201 is smoothly exposed from the opening 103.

[0075] Because of the concealed design, in order to ensure that the tail section 230 can work smoothly with the limiting part 104, the limiting part 104 can adopt the above-mentioned support platform or other structures, while the tail section 230 can adopt the above-mentioned straight structure.

[0076] From this, please refer to... Figure 6 When the pin 200 is in its natural state, the tail section 230 disengages from the limiting part 104. When it is necessary to drive the pin 200 from its natural state to its deformed state, applying a force to the tail section 230 will restrict the tail section 230 to the limiting part 104. (See reference...) Figure 8 .exist Figure 6 and Figure 8 In the example shown, the limiting part 104 is a support platform, and the tail section 230 is a linear structure.

[0077] In some embodiments, please refer to Figure 5 The pin 200 is inclined in the interface ring 100 at an angle to the axial direction of the interface ring 100.

[0078] Because the pin 200 is inclined in the interface ring 100, a greater force is required to drive the pin 200 from its natural state to its deformed state. When the pin 200 is in the deformed state, the internal stress of the pin 200 will be greater, thereby ensuring a more reliable connection between the contact point 201 and the contact part 11.

[0079] This application does not limit the tilt direction of the pin 200. For example, the pin 200 may include a first end 202 and a second end 203, wherein the first end 202 is away from the light guide portion 10, and the second end 203 is close to the light guide portion 10. The first end 202 may be further away from the axis of the interface ring 100, or it may be further close to the axis of the interface ring 100. It is understood that when the first end 202 is further away from the axis of the interface ring 100, reference can be made to... Figure 5 The bent section 220 is closer to the axis of the interface ring 100, thereby applying a force away from the axis to the tail section 230, allowing the pin 200 to accumulate greater internal stress. When the first end 202 is closer to the axis of the interface ring 100, the bent section 220 is further away from the axis of the interface ring 100, thereby applying a force closer to the axis to the tail section 230, which also allows the pin 200 to have greater internal stress.

[0080] To simplify the description and facilitate understanding, the embodiments of this application mainly use the example of the first end 202 being further away from the axis of the interface ring 100 to illustrate the tilt setting of the pin 200.

[0081] In some specific embodiments, the included angle is 2° to 5°. In specific designs, the included angle can be any one of 2°, 3°, 4°, and 5°, or a range of any two of them. By setting the included angle within the above range, the installation of the pin 200 can be simplified under the action of greater internal stress, so that the pin 200 can be stably connected to the interface ring 100.

[0082] In some embodiments, please refer to Figure 6 The pin 200 has a first end 202 and a second end 203. The second end 203 is close to the opening 103, the first end 202 is away from the axis of the interface ring 100, and the second end 203 is close to the axis of the interface ring 100. The second end 203 is adapted to be confined in the limiting part 104. The distance between the limiting part 104 and the axis is greater than the distance between the second end 203 and the axis.

[0083] Therefore, since the distance between the limiting part 104 and the axis is greater than the distance between the second end 203 and the axis, when the tail section 230 is restricted on the limiting part 104, the force applied to the tail section 230 needs to be greater, thus facilitating the formation of greater internal stress in the insert 200.

[0084] In some embodiments, the pin 200 includes a copper substrate and a first plating layer, a second plating layer, and a third plating layer sequentially disposed on the surface of the copper substrate. The first plating layer is made of nickel, the second plating layer is made of palladium-nickel, and the third plating layer is made of gold. The pin 200 adopts a four-layer structure design, consisting of a copper substrate made of copper material, a first plating layer made of nickel material, a second plating layer made of palladium-nickel material, and a third plating layer made of gold material, arranged sequentially from the inside out. This layered structure design, combined with different materials, enables the pin 200 to have strong corrosion resistance, preventing the pin 200 from rusting after cleaning, thereby extending the lifespan of the pin 200.

[0085] In some embodiments, please refer to Figure 5 and Figure 6 The interface ring 100 includes a first ring segment 110 and a second ring segment 120. The second ring segment 120 is sleeved on one end of the first ring segment 110. A mounting cavity 102 is formed between the first ring segment 110 and the second ring segment 120, or the second ring segment 120 forms the mounting cavity 102.

[0086] The second ring segment 120 can be a single-layer structure, in which case the space between the second ring segment 120 and the first ring segment 110 can form the mounting cavity 102. Alternatively, the second ring segment 120 can be a double-layer structure, so that the second ring segment 120 itself can form the aforementioned mounting cavity 102.

[0087] In some embodiments, the second ring segment 120 can be connected to the outer wall 121 of the first ring segment 110. When the length of the pin 200 is long, a pin through hole needs to be reserved at the connection position between the second ring segment 120 and the first ring segment 110 so that the pin 200 can pass through the pin through hole.

[0088] In some embodiments, please refer to Figure 3 , Figure 5 and Figure 6 The second ring segment 120 includes an outer wall 121, an inner wall 122, and an end wall 123 connecting the outer wall 121 and the inner wall 122. The inner wall 122, the outer wall 121, and the end wall 123 form an installation cavity 102. An opening 103 is provided on the inner wall 122, and the peripheral portion of the inner wall 122 corresponding to the opening 103 forms a limiting portion 104.

[0089] Specifically, the end wall 123 includes a first end wall 1231 and a second end wall 1232. The first end wall 1231 can be connected to the outer wall 121 of the first ring segment 110, and the aforementioned pin through hole can be formed on the first end wall 1231. The second end wall 1232 is disposed opposite to the first end wall 1231.

[0090] In the above embodiment, a portion of the inner wall 122 forms a limiting portion 104. Specifically, the portion of the inner wall 122 forming the limiting portion 104 is the part of the inner wall 122 near the opening 103. In other embodiments, the limiting portion 104 may also be installed on the inner wall 122.

[0091] In some embodiments, please refer to Figure 5 The outer wall 121 of the first ring segment 110 is provided with a support portion 130, which includes an inclined support surface, and the pin 200 is attached to the support surface.

[0092] It is understandable that, due to the presence of the support portion 130 and its inclined support surface, the natural shape of the pin 200 after it is attached to the support surface is an inclined state. The definition of the inclined state of the pin 200 can be found above.

[0093] In some embodiments, the distance between the support portion 130 and the axis of the interface ring 100 is less than the distance between the limiting portion 104 and the axis of the interface ring 100.

[0094] By setting the limiting part 104 further away from the axis of the interface ring 100, the pin 200 can be stably limited between the support part 130 and the limiting part 104. On the other hand, the tail section 230 of the pin 200 requires a greater force to be limited to the limiting part 104, thereby increasing the internal stress of the pin 200.
