[0049] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0050] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0051] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0052] References to "one embodiment", "some embodiments" or "an embodiment" described in the specification of this application mean that a particular feature, structure or characteristic described in conjunction with the embodiment is included in one or more embodiments of the present application. Thus, the phrases "in one embodiment", "in some other embodiments", "in some other embodiments", etc., which appear at different places in this specification, do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. In addition, in one or more embodiments, particular features, structures or characteristics may be combined in any suitable manner.

[0053] In order to illustrate the technical solution of the present application, a description is given below with reference to specific drawings and embodiments.

[0054] In the related art, various sensors in the ultrasonic endoscope are connected to the board through cables, and the ultrasonic host is also connected to the board through cables. The board connected to the sensor and the board connected to the main body are then connected together and electrically conductive to form a board assembly.

[0055] In traditional ultrasonic endoscopes, brackets are used to limit the board assembly. The board assembly is directly welded or bonded to the bracket. The space occupied by the bracket and the board assembly is the sum of the space occupied by the bracket and the board assembly, resulting in a larger space occupied by the bracket and the board assembly. Alternatively, the upper and lower shells of the connection part of the ultrasonic endoscope are directly used as brackets to press the board assembly, resulting in a waste of space in the thickness direction of the upper and lower shells. The size of the connection part in the thickness direction of the upper and lower shells needs to be increased to arrange other components. Therefore, the size of the connection part of the traditional ultrasonic endoscope is relatively large.

[0056] In order to solve the above problems, the present application provides a board limiting structure, a connecting part of an ultrasonic endoscope and an ultrasonic endoscope, which can reduce the space jointly occupied by the bracket and the board assembly, thereby reducing the size of the connecting part of the ultrasonic endoscope.

[0057] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , Figure 1 is a schematic diagram of the structure of an ultrasonic endoscope in one of the embodiments of the present application, Figure 2 yes Figure 1 The schematic structural diagram of the connecting portion 100 of the ultrasonic endoscope is shown in FIG. Figure 3 yes Figure 2 The structural diagram of the board card limiting structure 10 in the connecting part 100 is shown in FIG. Figure 4 yes Figure 3 The schematic structural diagram of the board limit structure 10 from another perspective is shown.

[0058] In a first aspect, an embodiment of the present application provides a board limit structure 10 for an ultrasonic endoscope. The ultrasonic endoscope includes a sensor. The board limit structure 10 includes a board assembly 11 and a bracket 12 .

[0059] The board assembly 11 includes a first board 111 and a second board 112 which are connected and electrically conductive. The first board 111 is used to be electrically connected to the sensor, and the second board 112 is used to be electrically connected to the ultrasound host.

[0060] The first board 111 and the second board 112 can be electrically connected by welding, or the first board 111 and the second board 112 can be electrically connected through a socket. The first board 111 and the second board 112 can be connected by welding, bonding, clamping, magnetic connection, screw connection or bolt connection. After the first board 111 and the second board 112 are connected together, the two can be used as a whole. The first board 111 can be electrically connected to the sensor through a cable 200, and the sensor may include an ultrasonic probe and a position sensor of an ultrasonic endoscope, etc. The second board 112 can be electrically connected to the ultrasonic host through the cable 200. For example, the first board 111 is connected to the ultrasonic cable 200 led out of the ultrasonic connector, and the second board 112 is connected to the ultrasonic cable 200 led out of the ultrasonic connector, and the ultrasonic connector is electrically connected to the ultrasonic host.

[0061] The bracket 12 is provided with a receiving groove 120 , and the board assembly 11 is disposed in the receiving groove 120 . Two opposite inner wall surfaces of the receiving groove 120 respectively abut against the first board 111 and the second board 112 .

[0062] Since the two opposite inner walls of the receiving groove 120 respectively abut the first board 111 and the second board 112, the first board 111 and the second board 112 can be limited by the two opposite inner walls of the receiving groove 120, that is, the board assembly 11 can be limited by the two opposite inner walls of the receiving groove 120. Wherein, when the receiving groove 120 has multiple inner walls, for example, when the receiving groove 120 has four inner walls, only two of the two opposite inner walls can abut the first board 111 and the second board 112 respectively. Alternatively, two of the two opposite inner walls can abut the first board 111 and the second board 112 respectively, and the other two opposite inner walls can also abut the first board 111 and the second board 112 respectively.

[0063] After the board-card assembly 11 is arranged in the receiving slot 120, the board-card assembly 11 may be completely located in the receiving slot 120, or part of the board-card assembly 11 may be located in the receiving slot 120 and part of the board-card assembly 11 may be located outside the receiving slot 120. When the board-card assembly 11 may be completely located in the receiving slot 120, the space jointly occupied by the board-card assembly 11 and the bracket 12 is only the space occupied by the bracket 12, which is smaller than the sum of the space occupied by the board-card assembly 11 and the space occupied by the bracket 12. When part of the board-card assembly 11 is located in the receiving slot 120 and part of the board-card assembly 11 is located outside the receiving slot 120, the space jointly occupied by the board-card assembly 11 and the bracket 12 is still smaller than the sum of the space occupied by the board-card assembly 11 and the space occupied by the bracket 12.

[0064] As can be seen from the above, the board limiting structure 10 provided in the embodiment of the present application, since the board assembly 11 includes a first board 111 and a second board 112 that are connected and electrically conductive, the bracket 12 is provided with a receiving groove 120, the board assembly 11 is arranged in the receiving groove 120, and the two opposite inner wall surfaces of the receiving groove 120 respectively abut the first board 111 and the second board 112, so not only can the first board 111 and the second board 112 be limited by the two opposite inner wall surfaces of the receiving groove 120, but also after the board assembly 11 is arranged in the receiving groove 120, the space jointly occupied by the board assembly 11 and the bracket 12 is smaller than the sum of the space occupied by the board assembly 11 and the space occupied by the bracket 12, which can reduce the space jointly occupied by the bracket 12 and the board assembly 11, thereby reducing the size of the connecting portion 100 of the ultrasonic endoscope.

[0065] Optionally, the shape of the bracket 12 can be set to a semi-cylindrical shape, a crescent shape, a semi-arc column, a cube, an irregular shape, or the like.

[0066] Please refer to Figure 5 , Figure 6 and Figure 7 , Figure 5 yes Figure 3 The top view of the board limit structure 10 is shown. Figure 6 yes Figure 5 A partial enlarged view of the middle A. Figure 7 yes Figure 3 The left side view of the board and card limiting structure 10 is shown.

[0067] In this embodiment, the first board 111 protrudes from the second board 112 along a first direction, and the second board 112 protrudes from the first board 111 along a second direction. The first direction and the second direction are opposite directions. Figure 5 and Figure 6In the figure, the first direction is the direction indicated by the arrow M, and the second direction is the direction indicated by the arrow N; the bracket 12 has a main body 121, a first limiting portion 122 and a second limiting portion 123 connected to each other, the first limiting portion 122 and the second limiting portion 123 are arranged in sequence along the first direction, and the first limiting portion 122 and the second limiting portion 123 respectively define a first inner wall surface 1220 of the accommodating groove 120 and a second inner wall surface 1230 of the accommodating groove 120, the first inner wall surface 1220 abuts against the first board card 111, and the second inner wall surface 1230 abuts against the second board card 112.

[0068] By adopting the above solution, the structure of the bracket 12 can be made simpler, and the first board 111 and the second board 112 can be limited by the first limiting portion 122 and the second limiting portion 123, that is, the board assembly 11 can be limited by the first limiting portion 122 and the second limiting portion 123.

[0069] Optionally, the main body 121, the first limiting portion 122 and the second limiting portion 123 can be integrally formed, such as integrally injection molded or integrally machined, etc. The main body 121, the first limiting portion 122 and the second limiting portion 123 can also be separately provided, and the first limiting portion 122 and the second limiting portion 123 can be connected to the main body 121 by welding, bonding, clamping, magnetic connection, screw connection or bolt connection.

[0070] Specifically, the first limiting portion 122 is provided with a first avoiding groove 1221 for accommodating the second board 112. Such a configuration allows one end of the second board 112 to extend to the outside of the accommodating groove 120 through the first avoiding groove 1221, facilitating the electrical connection between the second board 112 and the ultrasound host, and also allows the second board 112 to be further limited by the first limiting groove.

[0071] The second limiting portion 123 is provided with a second avoiding groove 1231 for accommodating the first board 111. Such a configuration allows one end of the first board 111 to extend to the outside of the accommodating groove 120 through the second avoiding groove 1231, facilitating electrical connection between the first board 111 and the sensor, and also allows the first board 111 to be further limited by the second limiting groove.

[0072] Please refer to Figure 8 , Figure 8 yes Figure 3 The schematic diagram of the structure of the board assembly 11 in the board limiting structure 10 is shown.

[0073] In order to make the first board 111 and the second board 112 connected more tightly, the board assembly 11 includes a first limiting sleeve 113, which is sleeved on the first board 111 and the second board 112. In this way, the first limiting sleeve 113 can enhance the connection strength between the first board 111 and the second board 112.

[0074] It can be understood that the first board 111 and the second board 112 may also be physically connected only through the first board 111 and the second board 112 .

[0075] Specifically, the material of the first limiting sleeve 113 may be metal or plastic. For example, the first limiting sleeve 113 may be adhesive tape or copper foil.

[0076] For example, the first limiting sleeve 113 is a heat shrink sleeve. After the first board 111 and the second board 112 are connected together, the heat shrink sleeve can be firstly put on the first board 111 and the second board 112, and then the heat shrink sleeve is heated with a hot air gun, so that the heat shrink sleeve shrinks inward and covers the first board 111 and the second board 112.

[0077] Please refer to Figure 2 , Figure 3 , Figure 5 and Figure 7 In this embodiment, at least two board components 11 and at least two receiving slots 120 are provided.

[0078] By adopting the above solution, multiple board assemblies 11 can be limited by the bracket 12 at the same time without increasing the space jointly occupied by the bracket 12 and the board assemblies 11, and the cable 200 can be placed in a part of the accommodating groove 120, and the cable 200 can be regulated and limited by the accommodating groove 120.

[0079] It is understandable that the number of board assemblies 11 required varies depending on the type of ultrasonic endoscope. For example, when performing a fan scan, four board assemblies 11 are sufficient, and when performing a circular scan, eight sets of board assemblies 11 are sufficient. In order to be compatible with multiple types, the number of accommodating slots 120 can be set to be larger, for example, eight accommodating slots 120 are set. When only four board assemblies 11 are needed, some of the accommodating slots 120 can be used to place the board assemblies 11, and the remaining accommodating slots 120 can be used to place the cables 200.

[0080] Among them, as an implementable method, the number of the accommodating grooves 120 is greater than the number of the board and card assemblies 11, and all the accommodating grooves 120 are connected. In this way, after all the board and card assemblies 11 are placed in the accommodating grooves 120, the cables 200 connected to the board and card assemblies 11 can be placed in the accommodating grooves 120 without the board and card assemblies 11, so that not only can the cables 200 be regulated and limited by the accommodating grooves 120, and the first board and card 111, the second board and card 112 and the cables 200 can be effectively fixed, but also the space occupied by the bracket 12, the board and card assemblies 11 and the cables 200 connected to the board and card assemblies 11 can be reduced, thereby reducing the size of the ultrasonic endoscope.

[0081] As another solution that can achieve the above effect, the board assembly 11 and the receiving groove 120 are arranged in a one-to-one correspondence, the depths of at least two receiving grooves 120 are not equal, and all the receiving grooves 120 are connected. In this way, after all the board assemblies 11 are placed in the receiving grooves 120, the cables 200 connected to the board assembly 11 can be placed in the receiving grooves 120 with a deeper depth, so that not only can the cables 200 be regulated and limited by the receiving grooves 120, but also the space occupied by the bracket 12, the board assembly 11 and the cables 200 connected to the board assembly 11 can be reduced, thereby reducing the size of the ultrasonic endoscope.

[0082] Please refer to Figure 5 For the four board assemblies 11 in the middle in the vertical direction, the depths of the receiving slots 120 corresponding to the two board assemblies 11 on the left and the two board assemblies 11 on the right are also different, that is, there is also a height difference, because the number of cables 200 required to be routed in the two board assemblies 11 on the left is different, and the required space is different. In this way, while reusing the space, the board and the cables 200 can fill the receiving slots 120 at the depth they are in.

[0083] As another solution that can achieve the above effect, multiple sets of board assemblies 11 are stacked in the same receiving slot 120. In this case, the vacant receiving slots 120 are used exclusively for placing cables 200, so as to facilitate centralized wiring and management. For example, one of the two middle receiving slots 120 is used exclusively for stacking board assemblies 11, and the other is used exclusively for placing cables 200. Alternatively, all board assemblies 11 are placed in the two middle receiving slots 120, and the cables 200 are placed in the two edge receiving slots 120.

[0084] For example, the bracket 12 is provided with a connecting cavity 124, and all the receiving grooves 120 are connected to the connecting cavity 124, so that all the receiving grooves 120 are connected. Such a configuration can ensure that the structure of the bracket 12 is relatively simple and easy to process while making all the receiving grooves 120 connected.

[0085] Optionally, the board and card limiting structure 10 includes a second limiting sleeve (not shown in the figure), which is sleeved on the bracket 12 and covers the notch of the accommodating groove 120. In this way, after the board and card assembly 11 is placed in the accommodating groove 120, the second limiting sleeve can further limit the board and card assembly 11 to prevent the board and card assembly 11 from moving out of the accommodating groove 120.

[0086] Specifically, the second limiting sleeve may be made of metal or plastic. For example, the second limiting sleeve may be made of adhesive tape or copper foil.

[0087] Please refer to Figure 2 and Figure 3 In the second aspect, the embodiment of the present application provides a connection portion 100 of an ultrasonic endoscope, comprising a housing 20 and a board limit structure 10 as in the first aspect. The housing 20 is provided with an installation cavity 21, and a bracket 12 of the board limit structure 10 is provided in the installation cavity 21.

[0088] The connecting portion 100 of the ultrasonic endoscope provided in the embodiment of the present application has a board assembly 11 including a first board 111 and a second board 112 that are connected and electrically conductive, and a bracket 12 is provided with a receiving groove 120. The board assembly 11 is arranged in the receiving groove 120, and the two opposite inner wall surfaces of the receiving groove 120 respectively abut against the first board 111 and the second board 112. Therefore, not only can the first board 111 and the second board 112 be limited by the two opposite inner wall surfaces of the receiving groove 120, but also after the board assembly 11 is arranged in the receiving groove 120, the space jointly occupied by the board assembly 11 and the bracket 12 is smaller than the sum of the space occupied by the board assembly 11 and the space occupied by the bracket 12, so that the space of the installation cavity 21 jointly occupied by the bracket 12 and the board assembly 11 can be reduced, so that the size of the shell 20 can be smaller, thereby reducing the size of the connecting portion 100 of the ultrasonic endoscope.

[0089] It can be understood that the connecting portion 100 of the ultrasonic endoscope provided in the embodiment of the present application can reduce the space of the installation cavity 21 jointly occupied by the bracket 12 and the board assembly 11, thereby making the size of the shell 20 smaller, or, more components can be arranged in the installation cavity 21 of the shell 20 without changing the size of the shell 20.

[0090] The board limit structure 10 provided in the embodiment of the present application can realize the design of the ultrasonic functional structure of the ultrasonic endoscope without adding additional structures and without increasing the size of the connecting part 100. The user's habits do not need to be changed, and the one-handed operability is extremely high, which ultimately greatly improves the user's operating experience.

[0091] For example, the shell 20 is in the shape of a body of revolution, such as a substantially cylindrical shape, and one end of the shell 20 along its own axial direction is a connection end, and the cable 200 connected to the sensor enters the installation cavity 21 from the connection end and is connected to the first board 111, and the cable 200 connected to the second board 112 extends from the connection end to the outside of the shell 20 and is connected to the ultrasound host. Such a configuration can avoid the problem of additionally providing a connector on the shell 20 extending in the radial direction of the shell 20 for connecting with the board assembly 11, resulting in a larger space occupied by the connection portion 100 in the radial direction of the shell 20.

[0092] Please refer to Figure 7 In this embodiment, the surface of the bracket 12 facing the housing 20 includes a first arc surface 125, and the inner wall surface of the mounting cavity 21 includes a second arc surface 22, and the second arc surface 22 is arranged in close contact with the first arc surface 125. In this way, the position of the bracket 12 relative to the housing 20 can be limited by the second arc surface 22 being arranged in close contact with the first arc surface 125.

[0093] Optionally, the connecting portion 100 includes a fixing member 30 connected to the housing 20, the fixing member 30 is arranged on the side of the bracket 12 away from the first arc surface 125, and the fixing member 30 abuts against the bracket 12. In this way, the fixing member 30 can abut against the bracket 12 to ensure that the second arc surface 22 and the first arc surface 125 are arranged in close contact, thereby preventing the bracket 12 from moving relative to the housing 20 in a direction perpendicular to the axial direction of the first arc surface 125, and can reduce the space occupied by the board and card limiting structure 10 and the cable 200 in the radial direction of the first arc surface 125. At the same time, it is convenient for the installation and maintenance of the cable 200, and the balance between the two is achieved, which can ensure that the board and card assembly 11 and the cable 200 are reliably restrained / fixed.

[0094] Specifically, the fixing member 30 and the housing 20 can be connected by welding, bonding, clamping, magnetic connection, screw connection or bolt connection. The fixing member 30 can be a plate-like member or a plastic film. The shape of the housing 20 can be set to be a semi-cylinder, a semi-arc column, or a semi-cylinder with a little flattened bottom. The connecting portion 100 provided in the embodiment of the present application can reuse the redundant space inside the housing 20, adjust the original structure to make it more compact, and move the original cable 200 upward.

[0095] The housing 20 may be a thin structure at both sides and thick in the middle, which can maximize the use of the internal space of the housing 20 without increasing the size of the housing 20. At the same time, the cables 200 are concentrated as much as possible to improve the space reuse rate and facilitate the installation and subsequent maintenance of the cables 200.

[0096] Please refer to Fig. 9 , Fig. 9 yes Figure 2 The internal structure schematic diagram of the connecting part 100 is shown.

[0097] In order to prevent the bracket 12 from moving relative to the shell 20 along the axial direction of the first arc surface 125, in the present embodiment, the connecting portion 100 includes a first stop member 40 and a second stop member 50 respectively arranged along the axial direction of the first arc surface 125, the first stop member 40 and the second stop member 50 are both connected to the shell 20, the first stop member 40 and the second stop member 50 are respectively located on both sides of the bracket 12, and the first stop member 40 and the second stop member 50 are both abutted against the bracket 12.

[0098] By adopting the above solution, the first stopper 40 and the second stopper 50 can be used to limit the bracket 12 in the axial direction of the first arc surface 125 to prevent the bracket 12 from moving relative to the housing 20 along the axial direction of the first arc surface 125 .

[0099] Optionally, the first stopper 40 and the second stopper 50 may be limit ribs. For example, the first stopper 40 is a limit rib provided on the shielding cover. After the board assembly 11 and the bracket 12 are assembled, the bracket 12 can be installed in the installation cavity 21, and then the shielding cover is locked by a nut, so as to limit the bracket 12. In this way, the original structure of the connecting part 100 can be reused as the first stopper 40 and the second stopper 50 to limit the bracket 12.

[0100] Optionally, the length direction of the first board 111 and / or the length direction of the second board 112 is parallel to the axial direction of the first arc surface 125. This arrangement can reduce the space occupied by the first board 111 and / or the second board 112 in the radial direction of the first arc surface 125 in the installation cavity 21.

[0101] In this embodiment, the dimension of the board assembly 11 along the depth direction of the receiving groove 120 is greater than the dimension of the board assembly 11 along the width direction of the receiving groove 120, and the depth direction of the receiving groove 120 is perpendicular to the length direction of the housing 20. Such a configuration can reduce the space occupied by the board assembly 11 in the width direction of the receiving groove 120, so that the dimension of the bracket 12 in the width direction of the receiving groove 120 can be smaller, thereby facilitating the arrangement of other components in the installation cavity 21.

[0102] For example, the housing 20 is roughly cylindrical, the length direction of the housing 20 is parallel to the axial direction of the housing 20, the width direction of the receiving groove 120 is parallel to the radial direction of the housing 20, the board assembly 11 is roughly rectangular, the dimension of the board assembly 11 along the depth direction of the receiving groove 120 is the width of the board assembly 11, the dimension of the board assembly 11 along the width direction of the receiving groove 120 is the height of the board assembly 11, and the dimension of the board assembly 11 along the length direction of the housing 20 is the length of the board assembly 11. When the length direction of the housing 20 is parallel to the horizontal plane, the board assembly 11 can be placed vertically in the receiving groove 120, at which time the space occupied by the board assembly 11 in the width direction of the receiving groove 120 is small, that is, the radial length of the housing 20 can be reduced.

The board assembly 11 is arranged in the receiving groove 120, and the two opposite inner wall surfaces of the receiving groove 120 respectively abut against the first board 111 and the second board 112. Therefore, not only can the first board 111 and the second board 112 be limited by the two opposite inner wall surfaces of the receiving groove 120, but also after the board assembly 11 is arranged in the receiving groove 120, the space jointly occupied by the board assembly 11 and the bracket 12 is smaller than the sum of the space occupied by the board assembly 11 and the space occupied by the bracket 12, so that the space of the installation cavity 21 jointly occupied by the bracket 12 and the board assembly 11 can be reduced, so that the size of the shell 20 can be smaller, the size of the connecting portion 100 of the ultrasonic endoscope is reduced, and the size of the ultrasonic endoscope is reduced.

[0105] Specifically, the sensor may include an ultrasonic probe and a position sensor of an ultrasonic endoscope, etc. The connecting portion 100, the operating portion 400 and the inserting portion 300 are sequentially connected, the inserting portion 300 may be a component for inserting into the patient's body, the sensor is provided in the inserting portion 300, and the operator controls the inserting portion 300 to work in the patient's body through the operating portion 400.

[0107] The endoscope system provided in the embodiment of the present application has a board assembly 11 of the ultrasonic endoscope including a first board 111 and a second board 112 that are connected and electrically conductive, and a bracket 12 provided with a receiving groove 120. The board assembly 11 is arranged in the receiving groove 120, and the two opposite inner wall surfaces of the receiving groove 120 respectively abut against the first board 111 and the second board 112. Therefore, not only can the first board 111 and the second board 112 be limited by the two opposite inner wall surfaces of the receiving groove 120, but also after the board assembly 11 is arranged in the receiving groove 120, the space jointly occupied by the board assembly 11 and the bracket 12 is smaller than the sum of the space occupied by the board assembly 11 and the space occupied by the bracket 12, so that the space of the installation cavity 21 jointly occupied by the bracket 12 and the board assembly 11 can be reduced, so that the size of the shell 20 can be smaller, the size of the connecting portion 100 of the ultrasonic endoscope is reduced, and the size of the ultrasonic endoscope is further reduced.

[0108] It is understandable that the light source host and the image processing device can be integrated into one, or the light source host and the image processing device can be provided separately.
