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.

[0059] In order to illustrate the technical solution of the present application, a description is given below with reference to specific drawings and embodiments.

[0060] In the related art, the optical hose and the ultrasonic hose are generally connected to the rubber sleeve of the connecting part first, and then the rubber sleeve is fixed to the shell of the connecting part. The traditional method is to connect the rubber sleeve and the shell together by threads. However, when the shape of the rubber sleeve is a special-shaped structure, such as a non-rotating structure, the rubber sleeve cannot be connected to the shell by threads, and it is not convenient to fix the rubber sleeve to the shell.

[0061] In order to solve the above problems, the present application provides a rubber sleeve fixing structure, an ultrasonic endoscope and its connecting part and an endoscope system, which can solve the problem in the related art that it is inconvenient to fix the rubber sleeve with a special-shaped structure on the shell.

[0062] 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 1000 in one embodiment of the present application. Figure 2 yes Figure 1 The schematic structural diagram of the connecting portion 100 in the ultrasonic endoscope 1000 is shown in FIG. Figure 3 yes Figure 2 The cross-sectional view of the connecting portion 100 along the MM direction is shown. Figure 4 yes Figure 3 A partial enlarged view of point A in the middle.

[0063] In the first aspect, an embodiment of the present application provides a rubber sleeve fixing structure 1100, which is used for an ultrasonic endoscope 1000. The rubber sleeve fixing structure 1100 includes a rubber sleeve assembly 10, a shell assembly 20 and a first connecting member 30. The rubber sleeve assembly 10 and the shell assembly 20 are arranged along a first direction, and the first connecting member 30 is located between the rubber sleeve assembly 10 and the shell assembly 20.

[0064] The shape of the rubber sleeve assembly 10 can be a special-shaped structure that is not easy to rotate. Figure 2 The first direction may be the axial direction of the rubber sleeve assembly 10 or the axial direction of the housing assembly 20. In the first direction, the first connector 30 may overlap with the rubber sleeve assembly 10 and / or the housing assembly 20.

[0065] The first connecting member 30 is detachably connected to the housing assembly 20 via a first connecting thread 301 , and the axis of the first connecting thread 301 is parallel to the first direction.

[0066] The first connection thread 301 may include a first internal thread provided on the first connection member 30 and a first external thread provided on the housing assembly 20. Alternatively, the first connection thread 301 may include a first external thread provided on the first connection member 30 and a first internal thread provided on the housing assembly 20.

[0067] The first connecting member 30 is detachably connected to the rubber sleeve assembly 10 .

[0068] Among them, when the first connecting member 30 and the rubber sleeve assembly 10 are in a connected state, the first connecting member 30 and the rubber sleeve assembly 10 are relatively fixed in the axial direction of the first connecting thread 301, and the first connecting member 30 can rotate around the axis of the first connecting thread 301 relative to the rubber sleeve assembly 10.

[0069] Since the first connecting member 30 and the shell assembly 20 are detachably connected via the first connecting thread 301, when the first connecting member 30 and the rubber sleeve assembly 10 are in a connected state, the first connecting member 30 and the rubber sleeve assembly 10 are relatively fixed in the axial direction of the first connecting thread 301, and the first connecting member 30 can rotate relative to the rubber sleeve assembly 10 around the axis of the first connecting thread 301. Therefore, it is only necessary to connect the first connecting member 30 and the shell assembly 20 together via the first connecting thread 301, and the shell assembly 20 and the rubber sleeve assembly 10 are relatively fixed in the axial direction of the first connecting thread 301. There is no need to rotate the rubber sleeve assembly 10, so that rubber sleeve assemblies 10 with various special-shaped structures can be fixed on the shell assembly 20 more conveniently.

[0070] As can be seen from the above, the rubber sleeve fixing structure 1100 provided in the embodiment of the present application, since the first connecting member 30 and the housing assembly 20 are detachably connected through the first connecting thread 301, the axis of the first connecting thread 301 is parallel to the first direction, and the first connecting member 30 and the rubber sleeve assembly 10 are detachably connected, wherein, when the first connecting member 30 and the rubber sleeve assembly 10 are in a connected state, the first connecting member 30 and the rubber sleeve assembly 10 are relatively fixed in the axis direction of the first connecting thread 301, and the first connecting member 30 can rotate relative to the rubber sleeve assembly 10 around the axis of the first connecting thread 301. Therefore, after the first connecting member 30 and the rubber sleeve assembly 10 are connected together and the first connecting member 30 and the housing assembly 20 are connected together through the first connecting thread 301, the housing assembly 20 and the rubber sleeve assembly 10 are relatively fixed in the axis direction of the first connecting thread 301, and there is no need to rotate the rubber sleeve assembly 10, so that the rubber sleeve assembly 10 of various special-shaped structures can be fixed on the housing assembly 20 more conveniently.

[0071] Furthermore, since the first connecting member 30 can rotate relative to the rubber sleeve assembly 10 around the axis of the first connecting thread 301, during the process of connecting the first connecting member 30 and the shell assembly 20 together through the first connecting thread 301, the first connecting member 30 can be rotated relative to the rubber sleeve assembly 10 around the axis of the first connecting thread 301, so that the first connecting member 30 can always be relatively fixed with the rubber sleeve assembly 10 in the axial direction of the first connecting thread 301.

[0072] The rubber sleeve fixing structure 1100 provided in the embodiment of the present application can be used for the connecting portion 100 of the ultrasonic endoscope 1000, or the operating portion 300 of the ultrasonic endoscope 1000 having a rubber sleeve assembly 10 with a special-shaped structure.

[0073] Please refer to Figure 5 and Figure 6 , Figure 5 yes Figure 2 The structural schematic diagram of the connecting portion 100 from another perspective is shown. Figure 6yes Figure 5 A partial enlarged view of point B in the middle.

[0074] In this embodiment, the rubber sleeve assembly 10 includes an inner component 11 and an outer rubber sleeve 12 arranged outside the inner component 11. The first connecting member 30 has a first stop surface 31 facing away from the shell assembly 20. The first stop surface 31 is in slidable contact with the surface of the outer rubber sleeve 12.

[0075] The rubber sleeve fixing structure 1100 further includes a second connecting member 40 connected to the embedded member 11 . The first connecting member 30 further includes a second stop surface 32 opposite to the first stop surface 31 . The second connecting member 40 is in slidable contact with the second stop surface 32 .

[0076] By adopting the above scheme, it is only necessary to connect the second connecting member 40 with the embedded member 11 so that the first stop surface 31 contacts the surface of the outer rubber sleeve 12, and the second connecting member 40 contacts the second stop surface 32. The first connecting member 30 can be limited by the second connecting member 40 and the outer rubber sleeve 12, so that the first connecting member 30 and the rubber sleeve assembly 10 are relatively fixed in the axial direction of the first connecting thread 301, thereby making the assembly process of the first connecting member 30 and the rubber sleeve assembly 10 simpler and more convenient.

[0077] Specifically, in a direction perpendicular to the first direction, the second connecting member 40 is located between the first connecting member 30 and the inner member 11. This arrangement can prevent the second connecting member 40 from occupying the space outside the first connecting member 30 and the inner member 11.

[0078] The inner insert 11 and the outer rubber sleeve 12 can be connected by clamping, screw connection or bolt connection. The outer rubber sleeve 12 can be a special-shaped structure, such as a flat cone or a flat truncated cone.

[0079] Alternatively, the outer rubber sleeve 12 is embedded in the inner insert 11. This arrangement can make the inner insert 11 and the outer rubber sleeve 12 more tightly connected, and the integrity of the rubber sleeve assembly 10 is better.

[0080] In order to facilitate the disassembly of the first connecting member 30 and the rubber sleeve assembly 10, the second connecting member 40 is optionally detachably connected to the inner member 11. In this way, when the first connecting member 30 and the rubber sleeve assembly 10 need to be disassembled, only the second connecting member 40 and the inner member 11 need to be disassembled to complete the disassembly process of the first connecting member 30 and the rubber sleeve assembly 10, which is simple and convenient to operate.

[0081] Specifically, the second connecting member 40 and the embedded member 11 can be detachably connected by means of a snap connection, a screw connection or a bolt connection.

[0082] For example, the second connecting member 40 is detachably connected to the embedded member 11 through the second connecting thread 401, the axis of the second connecting thread 401 is parallel to the first direction, and the rotation direction of the second connecting thread 401 is opposite to the rotation direction of the first connecting thread 301. Such a configuration can prevent the first connecting member 30 from driving the second connecting member 40 to rotate due to the friction between the first connecting member 30 and the second connecting member 40, thereby causing the second connecting member 40 to be disconnected from the embedded member 11 during the subsequent rotation of the first connecting member 30 relative to the rubber sleeve assembly 10 around the axis of the first connecting thread 301.

[0083] The second connection thread 401 may include a second internal thread provided on the second connection member 40 and a second external thread provided on the inner insert 11. Alternatively, the second connection thread 401 may include a second external thread provided on the second connection member 40 and a second internal thread provided on the inner insert 11.

[0084] The first connecting thread 301 may be a right-handed thread, and the second connecting thread 401 may be a left-handed thread. Alternatively, the first connecting thread 301 may be a left-handed thread, and the second connecting thread 401 may be a right-handed thread.

[0085] Optionally, in order to make it more convenient for humans or robots to drive the first connecting member 30 to rotate relative to the rubber sleeve assembly 10 around the axis of the first connecting thread 301, the first connecting member 30 is provided with a first locking portion 33. The first locking portion 33 may be a protrusion or a groove. The first locking portion 33 is used to cooperate with a tool (such as a wrench). The first locking portion 33 may be provided on the outer circumferential surface or end surface of the first connecting member 30.

[0086] Similarly, in order to make it more convenient for humans or robots to drive the second connecting member 40 to rotate relative to the embedded member 11 around the axis of the second connecting thread 401, the second connecting member 40 is provided with a second locking portion 41. The second locking portion 41 may be a protrusion or a groove. The second locking portion 41 is used to cooperate with a tool (such as a wrench). The second locking portion 41 may be provided on the outer circumferential surface or end surface of the second connecting member 40.

[0087] When assembling the above-mentioned rubber sleeve fixing structure 1100, the first connecting member 30 can be connected to the shell assembly 20 first, and then the second connecting member 40 can be connected to the embedded member 11. The first locking portion 33 is a groove provided on the outer circumferential surface of the first connecting member 30, and the second locking portion 41 is a groove provided on the end surface of the second connecting member 40, so as to avoid interference between the first locking portion 33 and the second locking portion 41 and other components and interference between the second locking portion 41 and the second connecting member 40.

[0088] Please refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 In this embodiment, a receiving groove 101 is provided between the inner insert 11 and the outer rubber sleeve 12 , at least a portion of the first connecting member 30 is located in the receiving groove 101 , and the first stop surface 31 is in slidable contact with the inner wall surface of the receiving groove 101 .

[0089] The outer rubber sleeve 12 includes a main body 121 and an extension portion 122. The main body 121 is connected to the inner component 11. The extension portion 122 and the inner component 11 define a receiving groove 101. The main body 121 and the extension portion 122 are connected, and the extension portion 122 can be folded relative to the main body 121 in a direction away from the first connecting member 30.

[0090] By adopting the above scheme, before the first connecting member 30 is rotated relative to the rubber sleeve assembly 10 around the axis of the first connecting thread 301, the extension portion 122 can be folded relative to the main body 121 in a direction away from the first connecting member 30, and after the first connecting member 30 is rotated relative to the rubber sleeve assembly 10 around the axis of the first connecting thread 301, the extension portion 122 can be folded relative to the main body 121 in a direction close to the first connecting member 30 and covered on the first connecting member 30, thereby protecting the first connecting member 30.

[0091] For example, the direction of the extension portion 122 away from the first connecting member 30 relative to the main body portion 121 may be Figure 4 The extending portion 122 may be deformed.

[0092] Optionally, the surface of the housing component 20 facing the rubber sleeve component 10 abuts against the extension portion 122. This arrangement can provide a better seal between the surface of the housing component 20 facing the rubber sleeve component 10 and the extension portion 122.

[0093] Please refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 In this embodiment, the shell assembly 20 includes a connecting head 21 and an outer shell 22 arranged outside the connecting head 21. The first connecting member 30 is detachably connected to the connecting head 21 through a first connecting thread 301, and at least part of the first connecting member 30 is located between the connecting head 21 and the outer shell 22.

[0094] By adopting the above solution, at least a portion of the first connecting member 30 can be located between the connecting head 21 and the outer shell 22 to protect the first connecting member 30 .

[0095] Specifically, the surface of the outer shell 22 facing the rubber sleeve assembly 10 abuts against the extending portion 122 .

[0096] Optionally, the connector 21 and the outer shell 22 may be connected by injection molding, bonding, threaded connection, screw connection, bolt connection or snap connection.

[0097] In the rubber sleeve fixing structure 1100 provided in the embodiment of the present application, in order to prevent the first connecting member 30 from driving the rubber sleeve assembly 10 to rotate relative to the housing assembly 20 due to the friction between the first connecting member 30 and the rubber sleeve assembly 10 when the first connecting member 30 and the housing assembly 20 are connected together through the first connecting thread 301, the rubber sleeve assembly 10 can be fixed manually or with a clamp. Alternatively, the following solution can also be adopted:

[0098] Please refer to Figure 7 , Figure 7 yes Figure 5 The schematic diagram of the structure of the ultrasonic hose 400, the optical hose 500, the embedded component 11 and the connector 21 in the connecting part 100 is shown.

[0099] Among them, the rubber sleeve assembly 10 is provided with a first limiting portion 102, and the shell assembly 20 is provided with a second limiting portion 201. The second limiting portion 201 can slide along the first direction relative to the first limiting portion 102, and the second limiting portion 201 cannot rotate around the axis of the first connecting thread 301 relative to the first limiting portion 102.

[0100] By adopting the above-mentioned scheme, it is possible to prevent the first connecting member 30 from driving the rubber sleeve assembly 10 to rotate relative to the shell assembly 20, causing the assembly shape of the rubber sleeve assembly 10 to change, during the process of connecting the first connecting member 30 and the shell assembly 20 through the first connecting thread 301. The entire process does not require the use of manual labor or clamps to fix the rubber sleeve assembly 10, and the operation is simpler and more convenient.

[0101] Specifically, the embedded component 11 is provided with a first limiting portion 102 , and the connecting head 21 is provided with a second limiting portion 201 .

[0102] Optionally, the first limiting portion 102 is configured as a first limiting protrusion, and the second limiting portion 201 is configured as a second limiting recess; or, the first limiting portion 102 is configured as a first limiting recess, and the second limiting portion 201 is configured as a second limiting protrusion.
