[0002] The ultrasonic endoscope is used to obtain ultrasonic echo information of a corresponding part by inserting an ultrasonic probe into a human body. The ultrasonic probe is connected to an ultrasonic endoscope host system through an ultrasonic connector to transmit the ultrasonic echo information received by the ultrasonic probe to the host and receive control signals sent by the host. In order to ensure safety (prevent cross infection, etc.), the ultrasonic connector needs to be detached from the ultrasonic endoscope host system before each use, and the probe with the ultrasonic connector needs to be disinfected and cleaned. In order to prevent the internal components of the ultrasonic connector from being affected by the liquid medicine and cleaning water, a waterproof cover is usually arranged at the opening of the ultrasonic connector in the prior art. However, the locking and unlocking of the waterproof cover relative to the ultrasonic connector in the prior art is relatively complex, which affects the disinfection and cleaning efficiency of the ultrasonic endoscope. SUMMARY

[0017] In one embodiment, the transmission assembly further includes a driven rod, which is rotatably connected to the cover about an axis parallel to the first axis and is transmissionally connected to the transmission part;

[0018] The locking assembly further includes a second hook connected to the driven rod, and the hook opening of the second hook is opposite to or away from the hook opening of the first hook. The driven rod is configured such that when the transmission part rotates relative to the cover about the first axis, it drives the second hook to rotate about the opposite direction to the first hook, so that the second hook engages or disengages from the mating part.

[0019] In one embodiment, the transmission assembly further includes two transmission wheels, which are respectively mounted on the transmission part and the driven rod, and the two transmission wheels are provided with meshing teeth in the circumferential direction.

[0026] Beneficial effects:

[0027] The ultrasonic connector waterproof cover provided in this application includes a cover body, a locking component, and a transmission component. The cover body has a mating groove for connector insertion. The locking component is movably connected to the cover body and has an unlocked position and a locked position. When the locking component is in the locked position, it locks into contact with the mating part of the connector. When the locking component is in the unlocked position, it separates from the mating part. The transmission component is rotatably connected to the cover body and is drively connected to the locking component. The transmission component is at least partially located outside the mating groove and is configured to be operably rotated relative to the cover body to drive the locking component to move between the unlocked position and the locked position. When the open side of the connector is inserted into the mating groove of the ultrasonic connector waterproof cover to seal the gap between the connector and the cover, the transmission component and the locking component are connected by transmission. By controlling the rotation of the transmission component relative to the cover, the locking component can be driven to move between the unlocked position and the locked position. This allows the mating part of the locking component and the connector to be locked or separated, thereby improving the stability of the seal between the connector and the ultrasonic connector waterproof cover. Since the transmission component is at least partially located outside the mating groove, it is easy to operate the rotation of the transmission component, which improves the efficiency of the installation and removal of the connector and the ultrasonic connector waterproof cover, and improves the efficiency of ultrasonic endoscope disinfection and cleaning.

[0028] This application also provides an ultrasonic endoscope, which includes a connector and the aforementioned ultrasonic connector waterproof cover, wherein the ultrasonic connector waterproof cover is detachably connected to the connector. This ultrasonic endoscope can achieve at least one of the aforementioned technical effects. Attached Figure Description

[0050] See Figure 1 and Figure 2 , Figure 1 This is a schematic diagram showing the mating of the ultrasonic connector waterproof cover and the connector according to an embodiment of this application. Figure 2 A partial cross-section of the ultrasonic connector waterproof cover and connector mating in one embodiment of this application. Figure 1An embodiment of this application provides a waterproof cover for an ultrasonic connector, comprising a cover body 100, a locking component 200, and a transmission component 300. The cover body 100 is provided with a mating groove 110 for inserting a connector 400. The locking component 200 is movably connected to the cover body 100 and has an unlocked position and a locked position. When the locking component 200 is in the locked position, it locks into contact with the mating portion 410 of the connector 400. When the locking component 200 is in the unlocked position, it separates from the mating portion 410. The transmission component 300 is rotatably connected to the cover body 100 and is drively connected to the locking component 200. The transmission component 300 is at least partially located outside the mating groove 110 and is configured to operably rotate relative to the cover body 100 to drive the locking component 200 to move between the unlocked position and the locked position.

[0051] Specifically, when the open side of the connector 400 is inserted into the mating groove 110 of the ultrasonic connector waterproof cover to seal the gap between the connector 400 and the cover 100, since the transmission component 300 is connected to the locking component 200, the locking component 200 can be driven to move between the unlocked position and the locked position by controlling the rotation of the transmission component 300 relative to the cover 100. This allows the locking component 200 to lock or separate from the mating part 410 of the connector 400, improving the stability of the seal between the connector 400 and the ultrasonic connector waterproof cover. Since the transmission component 300 is at least partially located outside the mating groove 110, it is easy to operate the rotation of the transmission component 300, improving the efficiency of installation and removal of the connector 400 and the ultrasonic connector waterproof cover, and improving the efficiency of ultrasonic endoscope disinfection and cleaning.

[0052] See Figure 2 In one embodiment, the transmission assembly 300 includes a rotating part 310 and a transmission part 320. The transmission part 320 is rotatably connected to the cover 100 about a first axis and is drively connected to the locking assembly 200. The rotating part 310 is rotatably connected to the cover 100 about a second axis and is drively connected to the transmission part 320. The transmission part 320 is configured to drive the locking assembly 200 to move between a locked position and an unlocked position under the rotation of the rotating part 310, wherein the first axis and the second axis intersect.

[0053] Specifically, in this application, the transmission part 320 is rotatably connected to the cover 100 about the first axis, and the rotating part 310 is rotatably connected to the cover 100 about the second axis, and the first axis and the second axis intersect. Thus, through the transmission arrangement of the rotating part 310 and the transmission part 320, the position of the part of the transmission assembly 300 located outside the mating groove 110 can be reasonably arranged, thereby improving the convenience of controlling the rotation of the transmission assembly 300.

[0054] Furthermore, the first axis is parallel to the length direction of the connector 400, and the portion of the transmission assembly 300 located outside the mating groove 110 is disposed on the side of the cover 100 opposite to the connector 400, i.e., the lower side of the cover 100. Preferably, the first axis and the second axis are perpendicular.

[0055] In other embodiments, the transmission assembly 300 includes a transmission part 320, which is at least partially located outside the mating groove 110. The transmission part 320 can be directly driven to rotate by driving the portion of the transmission part 320 located outside the mating groove 110, so as to enable the locking assembly 200 to move between a locked position and an unlocked position.

[0056] See Figure 2 , Figure 3 and Figure 4 , Figure 3 A schematic diagram of a portion of the transmission components in a waterproof cover for an ultrasonic connector provided in an embodiment of this application. Figure 1 . Figure 4 A partial cross-section of the ultrasonic connector waterproof cover and connector mating in one embodiment of this application. Figure 2 In one embodiment, on the first circumferential direction of the rotating part 310, the rotating part 310 is provided with a gradually raised first inclined surface 311 on the side facing the transmission part 320. The first inclined surface 311 is used to abut against the transmission part 320, and the first inclined surface 311 is configured to push the transmission part 320 to deflect around the first axis when the rotating part 310 rotates in a second circumferential direction opposite to the first circumferential direction, so as to drive the locking assembly 200 to move to the locking position.

[0057] Specifically, in the first circumferential upward rotation of the rotating part 310, the first inclined surface 311 gradually rises, so that during the rotation of the rotating part 310 in the second circumferential direction, the first inclined surface 311 can apply a thrust to the transmission part 320, causing the transmission part 320 to deflect, thereby driving the locking assembly 200 to move to the locked position. Compared to the transmission method using bevel gears or the like in the prior art, the gradually rising first inclined surface 311 in this application simplifies the transmission structure and reduces the space occupied by the rotating part 310, thus making the dimension of the ultrasonic connector waterproof cover in the depth direction of the mating groove 110 smaller, thereby miniaturizing the ultrasonic connector waterproof cover. Preferably, the second axis coincides with the axis of the rotating part 310.

[0058] See Figure 4 , Figure 5 , Figure 6 and Figure 7 , Figure 5 A partial cross-section of the ultrasonic connector waterproof cover and connector mating in one embodiment of this application. Figure 3 . Figure 6A schematic diagram of a portion of the transmission components in a waterproof cover for an ultrasonic connector provided in an embodiment of this application. Figure 2 . Figure 7 This is a partial schematic diagram of the ultrasonic connector waterproof cover and connector mating according to an embodiment of this application. In one embodiment, on the side of the rotating part 310 facing the transmission part 320 in the second circumferential direction, a gradually raised second inclined surface 312 is provided. The second inclined surface 312 is used to abut against the end of the transmission part 320 away from the first inclined surface 311, and the second inclined surface 312 is configured to push the transmission part 320 to deflect in the opposite direction around the first axis when the rotating part 310 rotates in the first circumferential direction, so as to drive the locking component 200 to move in the opposite direction to switch to the unlocked position.

[0059] Specifically, in the second circumferential upward movement of the rotating part 310, the second inclined surface 312 gradually rises. As the rotating part 310 rotates along the first circumferential direction, the second inclined surface 312 applies a thrust to the end of the transmission part 320 away from the first inclined surface 311, causing the transmission part 320 to deflect in the opposite direction, thereby driving the locking assembly 200 to move in the opposite direction to the unlocked position. Compared to the prior art method of transmitting power between the rotating part 310 and the transmission part 320 using bevel gears, the gradually rising second inclined surface 312 simplifies the transmission structure and reduces the space occupied by the rotating part 310. This results in a smaller dimension of the ultrasonic connector waterproof cover in the depth direction of the mating groove 110, thus miniaturizing the ultrasonic connector waterproof cover.

[0060] In other embodiments, the rotating part 310 and the transmission part 320 are driven by two bevel gears meshing together.

[0061] See Figure 3 , Figure 6 and Figure 8 , Figure 8 This is a partial cross-sectional view of a transmission component in an ultrasonic connector waterproof cover according to an embodiment of this application. In one embodiment, the transmission part 320 includes a transmission rod 321 and a swing arm 322. The transmission rod 321 is rotatably connected to the cover body 100 and is drively connected to the locking component 200. The swing arm 322 is connected to the transmission rod 321 and includes a first mating end 323 and a second mating end 324 disposed opposite to each other. Both the first mating end 323 and the second mating end 324 protrude relative to the transmission rod 321, and one of the first mating end 323 and the second mating end 324 is used to abut against a first inclined surface 311, and the other is used to abut against a second inclined surface 312.

[0062] Specifically, the swing arm 322 is sleeved on and fixedly connected to the transmission rod 321. The first mating end 323 is used to abut against the first inclined surface 311, and the second mating end 324 is used to abut against the second inclined surface 312. During the rotation of the rotating part 310 along the second circumferential direction, the first inclined surface 311 pushes the first mating end 323 to swing, thereby driving the transmission rod 321 to rotate around the first axis, so that the locking assembly 200 moves to the locked position; during the rotation of the rotating part 310 along the first circumferential direction, the second inclined surface 312 pushes the second mating end 324 to swing, thereby driving the transmission rod 321 to rotate in the opposite direction around the first axis, so that the locking assembly 200 moves in the opposite direction to the unlocked position. In this application, the volume of the transmission part 320 is greatly reduced by the cooperation of the transmission rod 321 and the swing arm 322. Simultaneously, it reduces interference between the transmission part 320 and the second inclined surface 312 during the swinging process of the first mating end 323 driven by the first inclined surface 311, and reduces interference between the transmission part 320 and the first inclined surface 311 during the swinging process of the second mating end 324 driven by the second inclined surface 312, thereby improving the reliability of the ultrasonic connector waterproof cover. Preferably, the first axis coincides with the axis of the transmission rod 321.

[0063] It should be noted that when the locking component 200 is in the locked position, it locks with the mating part 410 on the connector 400. When unlocking is required, the rotating part 310 is controlled to rotate around the first circumference, and the gap between the first inclined surface 311 and the first mating end 323 gradually increases, thereby reducing interference with the first inclined surface 311. When the locking component 200 is in the unlocked position, it separates from the mating part 410 on the connector 400. When locking is required, the rotating part 310 is controlled to rotate around the second circumference, and the gap between the second inclined surface 312 and the second mating end 324 gradually increases, thereby reducing interference with the second inclined surface 312.

[0064] See Figure 3 , Figure 6 and Figure 8 In one embodiment, the transmission part 320 is provided with an inclined first guide surface for abutting against a first inclined surface 311 for guiding; and / or, the transmission part 320 is provided with an inclined second guide surface 326 for abutting against a second inclined surface 312 for guiding.

[0065] Specifically, the first mating end 323 is provided with a first guide surface, and / or the second mating end 324 is provided with a second guide surface 326. This embodiment uses the second mating end 324 being provided with a second guide surface 326 as an example; please refer to the appendix of the specification. Figure 7With the second inclined surface 312 abutting against the second guide surface 326, the second guide surface 326 gradually rises toward the side of the second inclined surface 312 in the direction from the high end to the low end of the second inclined surface 312.

[0066] Furthermore, the second guide surface 326 is arc-shaped, and the second guide surface 326 is at least partially in contact with the second inclined surface 312 to avoid stress concentration.

[0067] See Figure 3 , Figure 6 In one embodiment, the rotating part 310 is provided with a clearance surface 313 on the side facing the transmission part 320. The clearance surface 313 is connected to and flush with the lower ends of the first inclined surface 311 and the second inclined surface 312, thereby reducing interference to the first mating end 323.

[0068] See Figure 3 , Figure 6 In one embodiment, the transmission part 320 is further provided with a first roller 325, the wheel surface of the first roller 325 is used to abut against the first inclined surface 311, and the first roller 325 is configured to rotate relative to the transmission part 320 under the drive of the rotating part 310.

[0069] Specifically, a first roller 325 is provided on the first mating end 323, so that when the first inclined surface 311 pushes the swing arm 322 to swing, the friction force can be reduced and the smoothness of the rotation of the transmission part 320 relative to the rotating part 310 can be improved.

[0070] See Figure 3 , Figure 6 In one embodiment, the transmission part 320 is further provided with a second roller, the wheel surface of the second roller is used to abut against the second inclined surface 312, and the second roller is configured to rotate relative to the transmission part 320 under the drive of the rotating part 310.

[0071] Specifically, a second roller is provided on the second mating end 324, so that when the second inclined surface 312 pushes the swing arm 322 to swing, the friction force can be reduced and the smoothness of the rotation of the transmission part 320 relative to the rotating part 310 can be improved.

[0072] See Figure 4 and Figure 7 In one embodiment, a first roller 325 is provided on the first mating end 323, and a second guide surface 326 is provided on the second mating end 324. In other embodiments, the second roller may be provided on the second mating end 324, and the first guide surface may be provided on the first mating end 323.

[0073] It should be noted that this application uses a method in which the first roller 325 is set on one of the first mating end 323 and the second mating end 324, and the second guide surface 326 is set on the other, so as to achieve a reasonable layout and avoid interference.

[0074] See Figure 9 , Figure 9 A partial cross-section of the ultrasonic connector waterproof cover and connector mating in one embodiment of this application. Figure 4 In one embodiment, the rotating part 310 and the transmission part 320 are accommodated in the mating groove 110, and the transmission assembly 300 also includes a knob 350, which is located outside the mating groove 110 and partially extends into the mating groove 110 and is connected to the rotating part 310.

[0075] Specifically, by housing the rotating part 310 and the transmission part 320 within the mating groove 110, the rotating part 310 and the transmission part 320 can be protected, thereby improving the reliability of locking and unlocking the mating part 410 of the control locking assembly 200 and the connector 400. It should be noted that in this embodiment, the transmission assembly 300 is at least partially located outside the mating groove 110, meaning the knob 350 is located outside the mating groove 110.

[0076] See Figure 9 In one embodiment, the cover 100 has a mounting hole 160 communicating with the mating groove 110. A knob 350 partially passes through the mounting hole 160 to connect with the rotating part 310. At least one second sealing strip 351 is provided between the knob 350 and the wall of the mounting hole 160 to seal the gap between the knob 350 and the mounting hole 160. The second sealing strip 351 is arranged around the circumference of the knob 350 and fixed to the knob 350. Preferably, there are two second sealing strips 351. Preferably, the second sealing strip 351 is a silicone ring.

[0077] Furthermore, the locking component 200 is housed in the mating groove 110, thereby avoiding the need for openings in the groove wall of the mating groove 110 and improving the reliability of the ultrasonic connector waterproof cover sealing the opening of the connector 400.

[0078] See Figure 2 and Figure 8 In one embodiment, there are two locking components 200, which are spaced apart along a direction parallel to the first axis. Each end of the transmission part 320 is connected to one locking component 200. The two locking components 200 engage with corresponding mating parts 410 on the connector 400 to improve stability when locked to the connector 400. The swing arm 322 is positioned at the middle of the transmission rod 321, thus stably driving the transmission rod 321 to rotate when the rotating part 310 rotates.

[0079] See Figure 4 and Figure 7 In one embodiment, the locking assembly 200 includes a first hook 210 connected to the transmission part 320; the first hook 210 is used to rotate synchronously with the transmission part 320 as it rotates about a first axis, so as to engage or disengage with the mating part 410.

[0080] Specifically, the first hook 210 is connected to the transmission rod 321, so that when the transmission rod 321 rotates around the first axis, it can drive the first hook 210 to rotate, so that the first hook 210 rotates in the locked position and the unlocked position, so as to engage or disengage with the mating part 410.

[0081] See Figure 4 and Figure 7 In one embodiment, the transmission assembly 300 further includes a driven rod 330, which is rotatably connected to the cover 100 about an axis parallel to the first axis and is connected to the transmission part 320 in a transmission manner; the locking assembly 200 further includes a second hook 220, which is connected to the driven rod 330, and the hook opening of the second hook 220 is opposite to or away from the hook opening of the first hook 210. The driven rod 330 is configured such that when the transmission part 320 rotates relative to the cover 100 about the first axis, it drives the second hook 220 to rotate about the opposite direction to the first hook 210, so that the second hook 220 engages or disengages from the mating part 410.

[0082] Specifically, the driven rod 330 is rotatably connected to the cover 100 about an axis parallel to the first axis and is drively connected to the transmission part 320. When the transmission part 320 rotates relative to the cover 100 about the first axis, it drives the driven rod 330 to drive the second hook 220 to rotate in the opposite direction to the first hook 210. Since the hook opening of the second hook 220 is opposite to or away from the hook opening of the first hook 210, when the first hook 210 engages with the mating part 410, the second hook 220 also engages with the mating part 410. This can stably limit the swaying of the ultrasonic connector waterproof cover and the connector 400 in the arrangement direction of the second hook 220 and the first hook 210, thereby improving the stability of the connection between the ultrasonic connector waterproof cover and the connector 400. Preferably, the driven rod 330 and the transmission rod 321 are arranged along the width direction of the connector 400.

[0083] Furthermore, the mating part 410 includes two spaced-apart limiting posts 411, with a first hook 210 and a second hook 220 located between the two limiting posts 411 and hooking into each of them. The first hook 210 and the second hook 220 are staggered on the first axis to avoid interference between them during rotation. Preferably, the first hook 210 and the second hook 220 are arranged along the width direction of the connector 400 on the first axis.

[0084] Furthermore, both the first hook 210 and the second hook 220 protrude from the side away from the rotating part 310 relative to the transmission rod 321, thereby reducing the height of the connector 400 and the ultrasonic connector waterproof cover and connector 400 when the first hook 210 and the second hook 220 are engaged with the limiting post 411, so as to further miniaturize the connector.

[0085] See Figure 8 In one embodiment, the transmission assembly 300 further includes two transmission wheels 340, which are respectively mounted on the transmission part 320 and the driven rod 330, and the two transmission wheels 340 are provided with meshing teeth 341 in the circumferential direction.

[0086] Specifically, the two drive wheels 340 mesh with each other, so that when the drive rod 321 rotates, it can drive the driven rod 330 to rotate in the opposite direction, thereby driving the second hook 220 to rotate in the opposite direction to the first hook 210. The drive wheels 340 are located at the ends of the drive rod 321 and the driven rod 330. Preferably, the drive wheels 340 on the drive rod 321 can be integrally formed with the drive rod 321. Preferably, the drive wheels 340 on the driven rod 330 can be integrally formed with the driven rod 330.

[0087] Furthermore, the teeth 341 are provided in the circumferential areas of the two transmission wheels 340. Compared with the method where the teeth 341 are provided on the entire outer circumference of the two transmission wheels 340, the space occupied by the transmission wheels 340 can be reduced, thus miniaturizing the ultrasonic connector waterproof cover.

[0088] See Figure 8 In one embodiment, there are two driven rods 330, and the two ends of the transmission rod 321 are respectively connected to one driven rod 330, and the two second hooks 220 are respectively connected to the corresponding driven rods 330.

[0089] See Figure 8In one embodiment, the transmission rod 321 is constructed from at least two rod segments connected end to end to facilitate its installation. The transmission rod 321 is rotatably connected to the cover 100 via bearings 360. Preferably, the transmission rod 321 is constructed from three rod segments connected end to end and is rotatably connected to the cover 100 via four bearings 360.

[0090] See Figure 9 In one embodiment, at least one protruding first sealing strip 120 is provided on the sidewall of the mating groove 110. The first sealing strip 120 is deformable and abuts against the outer wall of the connector 400 to seal the gap between the sidewall of the mating groove 110 and the connector 400. The first sealing strip 120 is arranged around the circumference of the cover 100. Preferably, there are two first sealing strips 120.

[0091] Further, the cover 100 includes a lower shell 130 and a flexible sleeve 140. The flexible sleeve 140 is connected to the lower shell 130, and the flexible sleeve 140 and the lower shell 130 form a mating groove 110. The flexible sleeve 140 is located on the side of the lower shell 130 facing the opening of the mating groove 110, and a first sealing strip 120 is disposed on the flexible sleeve 140. The first sealing strip 120 and the flexible sleeve 140 are integrally formed. The flexible sleeve 140 and the lower shell 130 are integrally formed by in-mold injection molding. Preferably, the flexible sleeve 140 is a silicone sleeve.

[0092] Furthermore, the ultrasonic connector waterproof cover also includes an upper shell 150, which is housed in a mating groove 110 and connected to the groove wall of the mating groove 110. The transmission rod 321 and the driven rod 330 are both rotatably connected to the upper shell 150.

[0093] See Figure 2 and Figure 10 , Figure 10This is a partial cross-sectional view of an ultrasonic endoscope provided in one embodiment of this application. This application also provides an ultrasonic endoscope, including a connector 400 and the aforementioned ultrasonic connector waterproof cover, the ultrasonic connector waterproof cover being detachably connected to the connector 400. In this application, when the open side of the connector 400 is inserted into the mating groove 110 of the ultrasonic connector waterproof cover to seal the gap between the connector 400 and the cover body 100, since the transmission component 300 is connected to the locking component 200, the locking component 200 can be driven to move between an unlocked position and a locked position by controlling the rotation of the transmission component 300 relative to the cover body 100. This allows the locking component 200 to lock or separate from the mating portion 410 of the connector 400, thereby improving the stability of the seal between the connector 400 and the ultrasonic connector waterproof cover. Since the transmission component 300 is at least partially located outside the mating groove 110, it facilitates the rotation of the transmission component 300, improving the efficiency of installing and removing the connector 400 and the ultrasonic connector waterproof cover, and improving the efficiency of ultrasonic endoscope disinfection and cleaning.

[0095] See Figure 10 , Figure 11 and Figure 12 , Figure 12This is a schematic diagram of a connector housing in an ultrasonic endoscope according to an embodiment of this application. In one embodiment, the connector 400 further includes a decorative sleeve 440, which is fitted onto the connector housing 490 and covers the fastening hole 491. The outer wall of the decorative sleeve 440 abuts against the mating groove 110. At least one first sealing member 420 is provided between the inner wall of the decorative sleeve 440 and the outer wall of the connector housing 490. The at least one first sealing member 420 is disposed on the side of the fastening hole 491 away from the opening of the mounting groove 493 to seal the gap between the decorative sleeve 440 and the outer wall of the connector housing 490, thereby preventing moisture and other substances from entering the plug 430 through the gap between the decorative sleeve 440 and the outer wall of the connector housing 490 via the fastening hole 491. The first sealing member 420 is arranged around the circumference of the connector housing 490. Preferably, the first sealing member 420 is a sealant.

[0096] Furthermore, there are two first seals 420, which are spaced apart along the depth direction of the mounting groove 493, and the fastening hole 491 is located between the two first seals 420.

[0098] Furthermore, the second seal 480 is arranged circumferentially around the inner ring 460 to stably seal the gap between the inner ring 460 and the wall of the mating hole 470. Preferably, the second seal 480 is an O-ring. The inner wall of the inner ring 460 is bonded to the outer wall of the outer tube 451 with sealant for sealing.
