[0035] In order to make the technical problems, technical solutions and beneficial effects to be solved by 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.

[0036] 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.

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.

[0039] As mentioned in the background technology, when in use, the ultrasonic endoscope can not only scan in real time through ultrasonic imaging to obtain ultrasonic images of different internal tissues of the human body, but also scan through optical imaging to obtain the surface morphological characteristics of internal tissues of the human body, effectively improving the efficiency and quality of medical diagnosis. In order to achieve the above functions, the ultrasonic endoscope needs to add an ultrasonic sensor to the original endoscope. At the same time, in order to achieve the communication connection between the ultrasonic sensor and the ultrasonic host, the connector part needs to add an additional circuit structure. However, due to the newly added circuit structure, the size of the entire connector is larger and inconvenient to operate. In addition, due to the need for a new circuit structure, the original endoscope needs to be redesigned, which increases the design cost.

[0040] To this end, the embodiment of the present application provides an ultrasonic connection part 100, a connector 1, an ultrasonic endoscope and an endoscope system, and by providing an independent ultrasonic connection part 100, the ultrasonic connection part 100 can be used to achieve a communication connection between the ultrasonic sensor 31 and the ultrasonic host 5, and the ultrasonic connection part 100 can be connected to the connector body 200 to form the connector 1. The above configuration ensures that the setting of the ultrasonic connection part 100 does not increase the size of the connector body 200, does not affect the operation of the connector body 200, and does not require the connector body 200 to be redesigned, thereby reducing the design cost.

[0041] First, an embodiment of the present application provides an endoscope system, including an image processing device, a light source device, a display device, and an ultrasonic endoscope. An imaging component, a light source component, and an ultrasonic sensor 31 are provided in the ultrasonic endoscope, wherein the light source device is used to provide a light source for the light source component in the endoscope to ensure that the endoscope can obtain images of the lesion site of the human body, the image processing device is communicatively connected with the imaging component in the endoscope, the image processing device is used to receive the optical image information transmitted by the imaging component, and process the optical image information, the external ultrasonic host 5 is used to receive the ultrasonic image information transmitted by the ultrasonic sensor 31 and process the ultrasonic image information, the display device is communicatively connected with the image processing device and the ultrasonic host 5 respectively, and the display device is used to display the processed ultrasonic image and optical image for the doctor to observe and assist the operation.

[0042] See also Figure 1 The ultrasonic endoscope provided in the embodiment of the present application is now described. The ultrasonic endoscope comprises an insertion portion 3, an operating portion 2 and a connector 1, wherein the insertion portion 3, the operating portion 2 and the connector 1 are connected in sequence, the insertion portion 3 is used to extend into the patient's body, the ultrasonic sensor 31 is arranged at the insertion portion 3, and the operator controls the insertion portion 3 to work in the patient's body through the operating portion 2.

[0043] The ultrasonic sensor 31 may include an ultrasonic probe and a position sensor.

[0044] In addition, the endoscope is also provided with an imaging component, a light source component and a pipeline component. Among them, the imaging component is used to obtain an optical image of the lesion site of the human body, and the light source component is used for lighting, so that the imaging component can obtain an optical image. The pipeline component can be used to transport water and gas to the head end of the insertion part to achieve cleaning of the light source component and the imaging component. The pipeline component can also achieve cleaning and gas injection of the human digestive tract, and is used to transport tools to the head end of the insertion part to achieve surgery, or to aspirate tissue fluid in the patient's body. Connector 1 is used to achieve communication connection between the imaging component and the image processing device, to achieve electrical connection between the light source component and the light source device, and to achieve connection between the pipeline component and the water source and the gas source.

[0045] See also Figure 1 , the connector 1 provided in the embodiment of the present application is now described. The connector 1 includes a connector body 200 and an ultrasonic connection part 100, and the ultrasonic connection part 100 is connected to the connector body 200. Among them, the ultrasonic connection part 100 is used to realize the communication connection between the ultrasonic sensor 31 and the ultrasonic host 5. The connector body 200 is used to realize the communication connection between the imaging component and the image processing device, to realize the electrical connection between the light source component and the light source device, and also to realize the connection between the pipeline component and the water source and the gas source.

[0046] The connector body 200 and the ultrasonic connector 100 may be fixedly connected, for example, by welding, bonding, or integral connection of the housing, etc. Alternatively, the connector body 200 and the ultrasonic connector 100 may be detachably connected, so that the ultrasonic connector 100 can be easily repaired and replaced.

[0047] Please also read Figures 5 to 7 , the ultrasonic connection part 100 provided in the embodiment of the present application is now described. The ultrasonic connection part 100 is used in an ultrasonic endoscope, and the ultrasonic endoscope includes an ultrasonic sensor 31 and a connector body 200. The ultrasonic connection part 100 is used to form a communication connection between the ultrasonic sensor 31 and the ultrasonic host 5 in the ultrasonic endoscope. The ultrasonic connection part 100 includes a shell assembly 110 and a board assembly 120. The shell assembly 110 is configured to be connected and connected to the connector body 200. The board assembly 120 is contained in the shell assembly 110. One end of the board assembly 120 is used to be electrically connected to the ultrasonic sensor 31, and the other end of the board assembly 120 is used to be electrically connected to the ultrasonic host 5.

[0048] It should be noted that the connector body 200 here is the connector 1 in a conventional endoscope, which has the functions of a conventional connector 1, such as being able to be used to realize the communication connection between the imaging component and the image processing device, to realize the electrical connection between the light source component and the light source device, and to realize the connection between the pipeline component and the water source and the gas source. The ultrasonic connection part 100 here is a circuit structure for forming a communication connection between the ultrasonic sensor 31 and the ultrasonic host 5 added to the ultrasonic endoscope on the basis of the conventional endoscope. The ultrasonic connection part 100 and the connector body 200 are combined to form the connector 1 of the ultrasonic endoscope.

[0049] In addition, the ultrasonic connection part 100 is in communication with the connector body 200 , which means that the ultrasonic connection part 100 is in communication with the inner cavity of the connector body 200 .

[0050] After the ultrasonic connection part 100 is connected and communicated with the connector body 200, the first ultrasonic cable extending from the ultrasonic sensor 31 of the insertion part 3 can be introduced into the housing assembly 110 through the position where the ultrasonic connection part 100 communicates with the connector body 200 to form a connection with one end of the board assembly 120. In addition, the second ultrasonic cable 4 extending from the ultrasonic host 5 can also be extended from the other end of the housing assembly 110 to be connected with the other end of the board assembly 120, thereby realizing the communication connection between the ultrasonic sensor 31 and the ultrasonic host 5.

[0051] The ultrasonic connection part 100 provided in the embodiment of the present application is independently provided with an ultrasonic connection part 100 outside the connector body 200 of the ultrasonic endoscope, and the communication connection between the ultrasonic sensor 31 and the ultrasonic host 5 is realized through the ultrasonic connection part 100. Since the ultrasonic connection part 100 is independently provided outside the connector body 200, the provision of the ultrasonic connection part 100 will not increase the size of the connector body 200, will not affect the operation of the connector body 200, and there is no need to redesign the connector body 200, thereby reducing the design cost. In addition, the position and angle of the ultrasonic connection part 100 relative to the connector body 200 can also be changed according to different design requirements to meet the different operation requirements and various treatment requirements of medical staff.

[0052] In one embodiment, see Figure 5 A first connection port 117 and a second connection port 118 are respectively provided at opposite ends of the shell assembly 110, wherein the first connection port 117 is connected to the connector body 200, the first connection port 117 is used for the first ultrasonic cable to pass through, and the second connection port 118 is used for the second ultrasonic cable 4 to pass through.

[0053] In one embodiment, see Figure 5 The housing assembly 110 and the board assembly 120 form a Z-axis limiting connection along the board assembly 120 and a rotation limiting connection around the Z-axis of the board assembly 120 .

[0054] The axial direction Z of the board assembly 120 refers to the extension direction of the two opposite ends thereof for connecting the ultrasonic sensor 31 and the ultrasonic host 5, that is, the direction in which one end of the two opposite ends extends toward the other end, that is, Figure 5 In the present embodiment, the housing assembly 110 is used to limit the axial direction of the board assembly 120, thereby preventing the board assembly 120 from moving along the axial direction Z during use or assembly, thereby preventing the structural connection from being unstable and the circuit from being unable to communicate normally. At the same time, the housing assembly 110 is used to limit the circumferential direction of the board assembly 120, thereby preventing the board assembly 120 from being entangled or twisted due to rotation during use.

[0055] In one embodiment, see Figure 2 , Figure 5 and Figure 8 The housing assembly 110 includes a sleeve 111 and an end cover 112. The board assembly 120 is accommodated in the sleeve 111. The inner wall of the sleeve 111 is formed with a first step surface 1111. The end cover 112 is connected to the sleeve 111. The board assembly 120 abuts between the first step surface 1111 and the end cover 112 along its axial direction Z.

[0056] During assembly, first install the board assembly 120 into the sleeve 111 until the board assembly 120 abuts against the first step surface 1111, then connect the end cover 112 to the sleeve 111, and tighten the board assembly 120 along the axial direction Z against the first step surface 1111 through the end cover 112 to form an axial Z limit for the board assembly 120.

[0057] The axial Z-limitation of the board assembly 120 is achieved by the interconnected end cover 112 and the sleeve 111 , which, on the one hand, facilitates the positioning of the board assembly 120 during assembly, and on the other hand, ensures that the board assembly 120 is securely positioned.

[0058] In the above example, see Figure 5 The end cover 112 is sleeved with the sleeve 111, specifically, the end of the end cover 112 is inserted into the sleeve 111, and the end of the end cover 112 is abutted against the board assembly 120, so as to press the board assembly 120 against the first step surface 1111. It can be understood that in other embodiments of the present application, a second step surface can also be formed on the inner peripheral wall of the end cover 112, and the board assembly 120 is limited by the first step surface 1111 and the second step surface, which is not the only limitation here.

[0059] In the above embodiment, the end cap 112 and the sleeve 111 are locked by screws, which not only ensures the connection reliability between the end cap 112 and the sleeve 111, and the axial Z limit reliability of the board assembly 120, but also makes the end cap 112 and the sleeve 111 detachable, which is convenient for the disassembly and maintenance of the board assembly 120. It can be understood that in other embodiments of the present application, the end cap 112 and the sleeve 111 can also be connected by riveting, bonding, welding or interference fit plug-in, which is not the only limitation here.

[0060] In one embodiment, see Figure 4 , Figures 7 to 9 The inner wall of the sleeve 111 is formed with a first plane 1112, and the outer wall of the board assembly 120 is formed with a second plane 1231. The first plane 1112 and the second plane 1231 are arranged in close contact with each other to limit the rotation of the board assembly 120 relative to the sleeve 111. When the board assembly 120 and the sleeve 111 need to rotate relative to each other, the board assembly 120 and the sleeve 111 need to be sleeved with a cylindrical surface. In this embodiment, the board assembly 120 and the sleeve 111 are arranged to be in contact with each other by the first plane 1112 and the second plane 1231, so that the rotation of the board assembly 120 can be limited, and the structure is simple and the manufacturing is simple.

[0061] In the above embodiment, the sleeve 111 and the board assembly 120 are mutually socketed, the inner wall surface of the sleeve 111 includes a first cylindrical surface 1113, the first cylindrical surface 1113 is circumferentially connected to the first plane 1112, the outer wall surface of the board assembly 120 includes a second cylindrical surface 1232, the second cylindrical surface 1232 is circumferentially connected to the second plane 1231, the first cylindrical surface 1113 and the second cylindrical surface 1232 are coaxially fitted, and the first plane 1112 and the second plane 1231 are fitted.

[0062] Specifically, the inner wall surface of the sleeve 111 includes two first cylindrical surfaces 1113 and two first planes 1112 along the circumferential direction, and the two first planes 1112 are symmetrically arranged, and the two first cylindrical surfaces 1113 are symmetrically arranged. Correspondingly, the outer wall surface of the board assembly 120 includes two second cylindrical surfaces 1232 and two second planes 1231, and the two second cylindrical surfaces 1232 are symmetrically arranged, and the two second planes 1231 are symmetrically arranged.

[0063] Among them, the arrangement of the first cylindrical surface 1113 and the second cylindrical surface 1232 enables the board assembly 120 to be arranged in a center relative to the sleeve 111, thereby reducing the size of the entire ultrasonic connector 100, and also facilitating the connection between the cables on both sides and the board assembly 120. It can be understood that in other embodiments of the present application, the rotation limit of the board assembly 120 can also be formed by plugging and matching the guide strips and guide grooves extending along the axial direction Z, or by buckling, which is not the only limitation here.

[0064] In one embodiment, see Figure 2 , Figure 4 and Figure 5 The sleeve 111 is provided with a shell 113 on its outer sleeve, and the shell 113 is used to be detachably connected to the connector body 200, or the shell 113 is integrally connected to the shell of the connector body 200.

[0065] The housing 113 is detachably connected to the connector body 200, that is, the housing 113 can be connected to the connector body 200, so that the ultrasonic connector 100 can be installed on the connector body 200 to realize the communication function of the ultrasonic connector 100. The housing 113 can be removed from the connector body 200 to realize the maintenance and replacement of the ultrasonic connector 100.

[0066] In addition, the shell 113 is integrally connected to the shell of the connector body 200, that is, the entire connector 1 can share one shell 113, and then the other structures of the ultrasonic connecting part 100 can be installed on the shell 113 in sequence. Such an arrangement can make the integrity of the entire connector 1 better and facilitate operation.

[0067] In this embodiment, through the setting of the shell 113, it is used to form a connection between the ultrasonic connecting part 100 and the connector body 200 on the one hand, and is also used to form a sealed connection with the soft rubber sleeve 114 on the other hand, so as to ensure the sealing effect of the ultrasonic connecting part 100 and ensure the appearance of the ultrasonic connecting part 100.

[0068] In one embodiment, see Figure 2 , Figure 4 and Figure 5 , a soft rubber sleeve 114 is also sleeved outside the end cover 112 and the sleeve 111, and the soft rubber sleeve 114 is sealed and connected to the outer shell 113. That is, the sleeve 111 and the end cover 112 are integrally covered inside by the outer shell 113 and the soft rubber sleeve 114, and the first ultrasonic cable is connected to the board assembly 120 through the outer shell 113 and the sleeve 111 in turn, and the second ultrasonic cable 4 is connected to the board assembly 120 through the soft rubber sleeve 114 and the end cover 112 in turn. Among them, the setting of the soft rubber sleeve 114 can not only play a guiding and limiting role for the second ultrasonic cable 4, but also ensure the sealed connection between the second ultrasonic cable 4 and the board assembly 120, and can also form a sealed connection with the outer shell 113 for the entire ultrasonic connection part 100.

[0069] For details, please refer to Figure 4 and Figure 5 The outer shell 113 is sleeved on the outside of a part of the sleeve 111, and the soft rubber sleeve 114 is sleeved on the outside of the end cover 112 and another part of the sleeve 111. The end of the soft rubber sleeve 114 and the end of the outer shell 113 are sleeved on each other, and a sealing connection is formed between the two through a first sealing ring.

[0070] In one embodiment, see Figure 2 , Figure 4 and Figure 5 The shell assembly 110 also includes a connecting tube 115, one end of which is sleeved with an end of the end cover 112 away from the sleeve 111, and the other end of the connecting tube 115 is used for allowing the second ultrasonic cable 4 to pass through and limit the second ultrasonic cable 4. The soft rubber sleeve 114 is sleeved on the outside of the connecting tube 115, and the soft rubber sleeve 114 and the connecting tube 115 are sealed and connected.

[0071] The connection tube 115 is provided to form a sealed connection between the soft rubber sleeve 114 and the end cover 112 , and is also used to guide the second ultrasonic cable 4 so that the second ultrasonic cable 4 is electrically connected to the board assembly 120 .

[0072] Optionally, the end cap 112 and the connecting pipe 115 are sleeved together and locked by screws. It can be understood that in other embodiments of the present application, the end cap 112 and the connecting pipe 115 can also be connected by bonding, welding or interference sleeve, which is not the only limitation here.

[0073] Optionally, the sleeve 111 and the end cover 112 are both made of hardware materials, which have high structural strength and signal shielding function, thereby facilitating the installation limit and signal shielding of the board assembly 120 and ensuring stable signal transmission of the board assembly 120.

[0074] Optionally, the soft rubber sleeve 114 is made of a soft rubber material, which has good structural flexibility and is easy to seal on one hand, and can follow the second ultrasonic cable 4 to change direction on the other hand, which is convenient for operating the second ultrasonic cable 4 .

[0075] Optionally, the connecting tube 115 can be made of plastic material or hardware material, and the outer wall of the connecting tube 115 is formed with an annular groove, and the second sealing ring is accommodated in the annular groove, and the second sealing ring abuts between the outer wall of the connecting tube 115 and the inner wall of the soft rubber sleeve 114, thereby forming a sealed connection. In this embodiment, in order to facilitate the second sealing ring to be sleeved on the outside of the connecting tube 115, and to facilitate the maintenance and replacement of the second sealing ring, the end cover 112 and the connecting tube 115 are independently provided. It can be understood that in other embodiments of the present application, when the connecting tube 115 and the soft rubber sleeve 114 are sealed by other means, such as by sealing by glue injection, the end cover 112 and the connecting tube 115 can be an integral connection structure.

[0076] In one embodiment, see Figure 5 A connecting ring 1131 is protruded from the inner wall of the shell 113, and the connecting ring 1131 divides the inner cavity of the shell 113 into a first cavity 1132 and a second cavity 1133. The sleeve 111 is accommodated in the first cavity 1132, and the second cavity 1133 is configured to communicate with the connector body 200 and to accommodate the first ultrasonic cable.

[0077] Specifically, for ease of description, the end of the sleeve 111 facing the connector body 200 is called the first end 1114, and the end of the sleeve 111 facing the ultrasound host 5 is called the second end 1115. The end cover 112 is installed on the second end 1115 of the sleeve 111, and the first step surface 1111 is set toward the end cover 112. During assembly, since it is necessary to connect the first ultrasonic cable with the board assembly 120, and then install the board assembly 120 into the sleeve 111 from the second end 1115 of the sleeve 111, that is, before assembly, the first ultrasonic cable connected to the ultrasonic sensor 31 needs to extend from the connector body 200, pass through the sleeve 111, and then extend from the second end 1115 of the sleeve 111 to form a connection with the board assembly 120. This requires that the reserved length of the first ultrasonic cable needs to be greater than the assembly length of the first ultrasonic cable in the ultrasonic endoscope. This arrangement allows the first ultrasonic cable to have a redundant length after assembly. This redundant length may cause the first ultrasonic cable to be easily wound and bent. In this embodiment, the second cavity 1133 is arranged so that the excess portion of the first ultrasonic cable can be accommodated in the second cavity 1133 without winding or occupying space in other places, and affecting the assembly of other structures.

[0078] In one embodiment, see Figure 2 , Figure 4 and Figure 5 The housing assembly 110 further includes a nut 116, and the first end 1114 of the sleeve 111 is connected to the connecting ring 1131 through the nut 116. Specifically, the first end 1114 of the sleeve 111 is inserted into the connecting ring 1131 after radially shrinking inward, and the first end 1114 of the sleeve 111 is locked together with the connecting ring 1131 through the nut 116.

[0079] When assembling the ultrasonic connecting part 100 in the embodiment of the present application, the outer shell 113 can be connected to the connector body 200 first, and then the sleeve 111 can be installed into the outer shell 113 and locked by the nut 116, and then the board assembly 120 is assembled, the end cover 112 is assembled, the connecting pipe 115 is assembled, and finally the soft rubber sleeve 114 is assembled.

[0080] In one embodiment, see Figures 9 to 13The board assembly 120 includes a bracket 121 and a plurality of board units 122. The bracket 121 is formed with a plurality of receiving slots 1211, and the board units 122 are received in the receiving slots 1211. The board units 122 include a first board 1221 and a second board 1222 that are electrically connected. The first board 1221 is used to be electrically connected to the ultrasonic sensor 31, and the second board 1222 is used to be electrically connected to the ultrasonic host 5. In practical applications, multiple signals need to be transmitted between the ultrasonic sensor 31 and the ultrasonic host 5, so different signals need to be transmitted through different board units 122. In this embodiment, by providing a plurality of receiving slots 1211 on the bracket 121, each board unit 122 can be received on the bracket 121, that is, each board unit 122 is formed into a whole, which is not only conducive to the assembly and transportation of the board assembly 120, but also conducive to the connection between the board assembly 120 and the cables on both sides. In addition, by accommodating each board unit 122 in the bracket 121, the occupied space of the entire board assembly 120 can be reduced.

[0081] Optionally, the first board 1221 and the second board 1222 are electrically connected by plugging through the board-to-board connector 1223. In other embodiments, the first board 1221 and the second board 1222 may also be electrically connected by welding.

[0082] In one embodiment, see Fig.11 The bracket 121 is formed with at least two rows of receiving grooves 1211 spaced apart along a first direction X, and each row of receiving grooves 1211 includes at least two receiving grooves 1211 distributed along a second direction Y; the first direction X is perpendicular to the axial direction Z of the board assembly 120, and the second direction Y is perpendicular to the axial direction Z of the board assembly 120.

[0083] In this embodiment, by distributing the receiving grooves 1211 along the first direction X and the second direction Y, that is, distributing the board units 122 along the first direction X and the second direction Y, the length of the board assembly 120 along the first direction X is not too long, and the length of the board assembly 120 along the second direction Y is not too long. Finally, the board assembly 120 is roughly circular, which not only has a compact structure and layout, occupies a small space, is easy to operate, but also has a beautiful appearance.

[0084] In a specific embodiment, see Fig.11, the bracket 121 is formed with two rows of receiving grooves 1211 spaced apart along the first direction X, and each row of receiving grooves 1211 includes four receiving grooves 1211 distributed along the second direction Y; the first direction X is the stacking direction of the first board 1221 and the second board 1222, and the second direction Y is the direction parallel to the first board 1221. In this embodiment, the bracket 121 includes eight board units 122, which are just used to realize the transmission of eight-way signals between the ultrasonic detector and the ultrasonic host 5, and the structure makes the entire board assembly 120 roughly circular. It can be understood that in other embodiments of the present application, the above-mentioned board assembly 120 can also include more than eight board units 122, for example, the board assembly 120 can also be used for power signal transmission and optical image signal transmission. In addition, the board units 122 can also be three or four rows along the first direction X, and each row can also be two, three, five or more board units 122, which are not limited here.

[0085] In one embodiment, see Figures 11 to 13 Each row of receiving grooves 1211 passes through the opposite sides of the bracket 121 along the second direction Y, and a support plate 1213 is provided at the middle position of each row of receiving grooves 1211 of the bracket 121, and the receiving grooves 1211 located on the same side of the support plate 1213 are connected; a first heat shrink tube 123 is provided on the outside of the bracket 121.

[0086] Among them, by setting each row of receiving grooves 1211 through the opposite sides of the bracket 121 along the second direction Y to form a side opening 1212, when assembling the board unit 122, the board unit 122 can be loaded into the receiving groove 1211 from the position of the side opening 1212. At the same time, a support plate 1213 is set at the middle position of the bracket 121, and the board units 122 on both sides can be supported and positioned by the support plate 1213, so that each board unit 122 can be neatly loaded into each receiving groove 1211 in sequence. The setting of the receiving grooves 1211 on the same side of the support plate 1213 being connected can reduce the space occupied by the board unit 122 in the bracket 121, thereby reducing the size of the bracket 121. In addition, the setting of the first heat shrink tube 123 can ensure that each board unit 122 is firmly assembled in the bracket 121.

[0087] In one embodiment, see Fig.12 and Fig.13 The receiving groove 1211 has a first inner wall 1214 and a second inner wall 1215 along the first direction X. The first inner wall 1214 and the second inner wall 1215 are respectively arranged to fit the first board card 1221 and the second board card 1222, so that the board card unit 122 can be limited along the first direction X.

[0088] In one embodiment, see Fig.12and Fig.13 A first limit block 1216 is protruding from the first inner wall 1214, and a second limit block 1217 is protruding from the second inner wall 1215, wherein the first limit block 1216 is used to abut against the first board 1221 along the axial direction Z of the board assembly 120, and the second limit block 1217 is used to abut against the second board 1222 along the axial direction Z of the board assembly 120, that is, the first board 1221 and the second board 1222 are abutted and limited between the first limit block 1216 and the second limit block 1217, thereby realizing the limitation of the board unit 122 along the axial direction Z.

[0089] In addition, a first through slot 1218 is formed between the first stop block 1216 and the second inner wall 1215, and a second through slot 1219 is formed between the second stop block 1217 and the second inner wall 1215. The end of the second plate card 1222 for connecting with the second ultrasonic cable 4 extends from the first through slot 1218, and the end of the first plate card 1221 for connecting with the first ultrasonic cable extends from the second through slot 1219.

[0090] In one embodiment, the first limiting block 1216 and the second limiting block 1217 of the two mutually communicating receiving grooves 1211 are also integrally connected.

[0091] In one embodiment, see Fig.13 The board unit 122 further includes a second heat shrink tube 1224, which is sleeved on the outside of the first board 1221 and the second board 1222 to form the board unit 122 into a whole. The second heat shrink tube 1224 can, on the one hand, make the electrical connection between the first board 1221 and the second board 1222 firm and prevent it from loosening, and on the other hand, make the entire board unit 122 form a whole, which is convenient for assembling the board unit 122 in the bracket 121.

[0092] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
