[0002] When performing automatic breast full-volume ultrasound imaging, a wide-band, high-frequency, three-dimensional ultrasound probe is used for all-round scanning, and the image is then stored in a post-processing workstation. In this process, a coupling agent is required. A coupling agent generally refers to a substance used to improve the efficiency of ultrasound transmission during ultrasound examinations. It is usually a water-based gel that can fill the gap between the ultrasound probe and the skin, reducing the energy loss of ultrasound during transmission, thereby improving image quality and accuracy. Therefore, we need a coupling agent applicator to evenly cover the patient's breasts with a thin layer of coupling agent to facilitate probe scanning.

[0003] The application head of the existing applicator is usually an integrated structure with the handle. The operator uses the applicator to apply the coating by holding the handle. However, this makes it difficult to disassemble and clean the application head, resulting in the inability to thoroughly clean the interior and surface, increasing the risk of cross infection. In addition, since the application is done manually, uneven application will occur, thereby reducing the clarity of the image. In view of the above problems, a person skilled in the art has proposed a coupling agent applicator for three-dimensional breast ultrasound examination to solve the above problems.

[0006] Furthermore, the coating liquid assembly includes a placement groove, which is opened inside the handle, and a slider is slidably connected inside the placement groove. The top of the slider is rotatably connected to a movable rod, the bottom of the slider is fixedly connected to a connecting rod, and the other end of the connecting rod is fixedly connected to a piston. The outer sleeve of the connecting rod is provided with a spring 2, and a storage bottle is installed inside the handle below the placement groove.

[0007] Furthermore, the left and right sides of the exterior of the handle are fixedly connected with reinforcement rods, and the other ends of the reinforcement rods are fixedly connected to the exterior of the mounting plate.

[0008] Furthermore, the outside of the movable block is slidably connected to the inside of the limiting groove, and the spring is set on the outside of the pull rod.

[0009] Furthermore, the outside of the card block is engaged with the inside of the card slot on an adjacent side.

[0010] Furthermore, a plurality of liquid outlet holes are provided inside the coating head, and a connecting hole is provided below the internal storage bottle of the handle, and the connecting hole passes through the inner wall of the mounting plate and the connecting block and extends to the interior of the coating head.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a coupling agent applicator for three-dimensional breast ultrasound examination, including a handle 1 and a movable block 7, the lower end of the handle 1 is fixedly connected to a mounting plate 2, the left and right sides of the interior of the mounting plate 2 are provided with limiting grooves 5, the interior of the limiting groove 5 is fixedly connected with a spring 1 6, the adjacent sides of the two springs 1 6 are fixedly connected with a clamping block 9, the other side of the spring 1 6 is fixedly connected with a pull rod 8, the interior of the mounting plate 2 is slidably connected with a connecting block 4, the bottom of the connecting block 4 is fixedly connected with an applicator head 3, the left and right sides of the connecting block 4 are provided with clamping grooves 10, the interior of the handle 1 is provided with a coating liquid assembly, the exterior of the movable block 7 is slidably connected to the interior of the limiting groove 5, the spring 1 6 is sleeved on the exterior of the pull rod 8, and the exterior of the clamping block 9 is engaged with the interior of the clamping groove 10 on the adjacent side.

[0023] Specifically, by fixing the handle 1 with the mounting plate 2 and installing the applicator head 3 on the mounting plate 2, it is convenient for the user to hold the applicator to apply the coupling agent, and the operation is simple and easy to use. By pulling the pull rods 8 on both sides of the mounting plate 2, the pull rods 8 drive the movable block 7 to slide inside the limiting groove 5. The limiting groove 5 can limit the movement of the movable block 7 to ensure the stability of the structure, thereby causing the spring 6 to contract, and the movable block 7 will drive the card block 9 to disengage from the card slot 10, so that the applicator head 3 can be separated from the mounting plate 2, which is convenient for thorough cleaning of the applicator head 3, reduces the risk of infection, and improves the safety of use. When installing the applicator head 3, the spring 6 can release the elastic potential energy after loosening the pull rod 8 to push the movable block 7 to move, so that the card block 9 enters the card slot 10, thereby realizing the installation and fixation of the applicator head 3, and the spring 6 is sleeved on the outside of the pull rod 8 to maintain horizontal movement during extension and retraction.

[0024] Reference Figure 3 The coating liquid assembly includes a placement groove 12, which is opened inside the handle 1. A slider 13 is slidably connected inside the placement groove 12. The top of the slider 13 is rotatably connected to a movable rod 17. A connecting rod 14 is fixedly connected to the bottom of the slider 13. A piston 16 is fixedly connected to the other end of the connecting rod 14. A spring 15 is sleeved on the outside of the connecting rod 14. A storage bottle 19 is installed inside the handle 1 below the placement groove 12. A pressure rod 18 is rotatably connected to the outside of the handle 1. The outside of the pressure rod 18 is rotatably connected to one end of the movable rod 17. The outside of the piston 16 is slidably connected to the inside of the storage bottle 19. A feeding pipe 21 is provided at the rear through hole of the handle 1.

[0025] Specifically, the placement groove 12 limits the movement of the slider 13, so that the slider 13 can maintain vertical sliding, thereby ensuring the stability of the structure. By pressing the pressure rod 18, the movable rod 17 can be pushed to move, so that the movable rod 17 applies pressure to the slider 13, thereby pushing the slider 13 to slide inside the placement groove 12. When the slider 13 moves, the piston 16 can be pushed to move inside the storage bottle 19 through the connecting rod 14, thereby squeezing out the coupling agent in the storage bottle 19, and after flowing through the connecting hole 20 at the bottom thereof, passing through the mounting plate 2 and the connecting block 4, it flows into the interior of the application head 3, and finally flows out through the multiple liquid outlet holes 22, so that the user can evenly apply the coupling agent on the patient's breasts, ensuring the clarity of the image during the examination, and providing a better imaging effect for the entire examination process.

[0026] Reference Figure 1 The left and right sides of the outside of the handle 1 are fixedly connected with reinforcement rods 11, and the other end of the reinforcement rod 11 is fixedly connected to the outside of the mounting plate 2.

[0027] Specifically, by connecting the two ends of the reinforcing rod 11 to the outside of the handle 1 and the mounting plate 2 respectively, the applicator can be made more secure and the stability of the structure is ensured.

[0028] Reference Figure 3 A plurality of liquid outlet holes 22 are provided inside the coating head 3 , and a connecting hole 20 is provided below the internal storage bottle 19 of the handle 1 . The connecting hole 20 passes through the inner wall of the mounting plate 2 and the connecting block 4 and extends to the interior of the coating head 3 .

[0029] Specifically, the coupling agent squeezed out of the storage bottle 19 can flow to the inside of the applicator head 3 through the connecting hole 20, and then the coupling agent can flow out through the multiple liquid outlet holes 22 to evenly cover the patient's breasts, thereby ensuring the imaging effect.

[0030] Working principle: When using this applicator, after adding coupling agent to the storage bottle 19 through the feeding tube 21, you can hold the handle 1 and press the pressure rod 18, and push the movable rod 17 to move through the pressure rod 18, so that the movable rod 17 applies pressure to the slider 13, so that the slider 13 slides inside the placement groove 12. At this time, the spring 15 contracts, and the slider 13 pushes the piston 16 to move inside the storage bottle 19 through the connecting rod 14, so that the coupling agent therein is squeezed out, and flows to the inside of the application head 3 through the connecting hole 20 at the bottom of the storage bottle 19, and finally flows out through multiple liquid outlets 22, so that the user can apply the coupling agent more evenly when applying it, ensuring a better imaging effect during the inspection process.

[0031] If the applicator head 3 needs to be removed for cleaning and disinfection, the pull rods 8 on both sides of the mounting plate 2 can be pulled to drive the movable block 7 to slide inside the limiting groove 5 through the pull rods 8, thereby causing the spring 6 to contract. At the same time, the movable block 7 will drive the card block 9 to disengage from the card slot 10, thereby separating the applicator head 3 from the mounting plate 2, facilitating a thorough cleaning of the applicator head 3, reducing the risk of infection and improving safety of use. When installing, only the above steps need to be repeated, and after the connecting block 4 is inserted into the interior of the mounting plate 2, the pull rod 8 is released to allow the spring 6 to return to its original state, thereby pushing the card block 9 into the card slot 10 on the adjacent side to complete the installation and fixation of the applicator head 3.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
