Description

Technical Field

[0001] This invention relates to the field of ultrasonic testing devices, specifically to a pelvic floor ultrasonic testing device with a movable mechanism. Background Technology

[0002] Ultrasound testing devices are instruments that diagnose diseases by displaying the reflection and attenuation patterns of ultrasound waves as they propagate through the human body on an oscilloscope screen. Ultrasound waves have good directionality; when they encounter tissues and organs of different densities during propagation, phenomena such as reflection, refraction, and absorption occur. Based on the distance, intensity, quantity, and attenuation of the echoes displayed on the oscilloscope screen, the activity and function of certain organs can be displayed, and it can accurately identify whether tissues and organs contain liquids or gases, or whether they are solid tissues. In gynecology, when examining the pelvic floor, transabdominal examination is usually used, with the bladder as the acoustic window. However, traditional transabdominal ultrasound probe devices require coating the probe surface with a coupling fluid to reduce the influence of the gap between the probe and the skin. Uneven distribution of the coupling fluid can lead to a decrease in detection clarity. Summary of the Invention

[0003] The purpose of this invention is to provide a pelvic floor ultrasound detection device with a movable mechanism to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a pelvic floor ultrasonic testing device with a moving mechanism, comprising an outer shell, an inner shell, a piezoelectric ceramic, a matching layer, a fixed acoustic lens, and a movable acoustic lens. The inner shell is fixedly disposed inside the outer shell, and the piezoelectric ceramic is fixedly disposed inside the inner shell. A matching layer is fixedly disposed on one side of the piezoelectric ceramic. A fixed acoustic lens is fixedly disposed on the side of the matching layer away from the piezoelectric ceramic. A movable acoustic lens is movably disposed on the side of the fixed acoustic lens away from the matching layer. A medium is sealed and filled between the fixed acoustic lens and the movable acoustic lens. A medium driving structure is disposed inside the outer shell, which can drive the movable acoustic lens to move axially via the medium. A rotation driving structure is disposed inside the outer shell, which can drive the movable acoustic lens to rotate.

[0005] The medium driving structure includes a medium sealing ring, a sealing convex ring, a sealing rubber ring, a limiting convex ring, a medium connecting pipe, a medium pipeline, a piston disc, a limiting connecting rod, a limiting square hole, a threaded sleeve, a driving screw, and a medium motor.

[0006] The medium sealing ring is fixedly installed on the outer surface of the fixed acoustic lens. A sealing protrusion is fixedly provided on the inner surface of the medium sealing ring, and a sealing rubber ring is fixedly provided on the inner surface of the sealing protrusion. The sealing rubber ring is in sealing contact with the outer surface of the movable acoustic lens.

[0007] A limiting protrusion ring is fixedly provided on the outer surface of the movable acoustic lens, near the side where the fixed acoustic lens is located. A medium connecting pipe is fixedly connected to the outer surface of the medium sealing ring. A medium pipeline is fixedly connected to the other end of the medium connecting pipe. A piston disc is movably provided inside the medium pipeline.

[0008] A limiting link is fixedly installed on one side surface of the piston disc, and a limiting square hole is opened through the end of the medium pipeline. The limiting link passes through the limiting square hole and can only move axially within the limiting square hole, but cannot rotate.

[0009] The end of the limiting link is fixedly provided with a threaded sleeve, and the inside of the threaded sleeve is provided with a drive screw. The drive screw is connected to the medium motor for transmission, and the medium motor is fixedly installed with the outer shell.

[0010] The rotary drive structure includes a rotary convex ring, a driven gear ring, a drive shaft gear, and a drive motor.

[0011] The rotating convex ring is fixedly installed on the outer surface of the movable acoustic lens. A driven gear ring is fixedly provided on the inner surface of the rotating convex ring. The drive shaft teeth mesh with the driven gear ring. The drive shaft teeth are driven and installed with the drive motor. The drive motor is fixedly installed with the outer shell.

[0012] A tail shank is fixedly provided on one side of the outer shell, and a backing plate is fixedly provided inside the inner shell on the side of the piezoelectric ceramic away from the matching layer.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The ultrasound detection device of the present invention features a movable acoustic lens that can rotate relative to a fixed acoustic lens. This allows the coupling fluid coated on the surface of the movable acoustic lens to actively and evenly distribute during pelvic ultrasound detection, improving the clarity of the ultrasound detection. Furthermore, by using rotation instead of the medical personnel's hand movements, it enables more stable targeted local detection.

[0015] The medium-driven structure allows for axial movement of the movable acoustic lens, which in turn changes the focal point of the movable acoustic lens. This facilitates focal length adjustment during the detection process. Furthermore, the medium filling prevents air gaps between the fixed and movable acoustic lenses, thus avoiding any impact on detection accuracy. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1 to 5This invention provides a technical solution: a pelvic floor ultrasonic testing device with a movable device, comprising an outer shell 1, an inner shell 2, a piezoelectric ceramic 3, a matching layer 4, a fixed acoustic lens 5, and a movable acoustic lens 6.

The matching layer 4 is fixedly disposed on one side of the piezoelectric ceramic 3. The fixed acoustic lens 5 is fixedly disposed on the side of the matching layer 4 away from the piezoelectric ceramic 3. The movable acoustic lens 6 is movably disposed on the side of the fixed acoustic lens 5 away from the matching layer 4. A medium is sealed and filled between the fixed acoustic lens 5 and the movable acoustic lens 6. The medium can be a coupling fluid or other liquid that can reduce the impact of the gap between the fixed acoustic lens 5 and the movable acoustic lens 6. A medium driving structure is disposed inside the outer shell 1, which can drive the movable acoustic lens 6 to move axially through the medium. A rotation driving structure is disposed inside the outer shell 1, which can drive the movable acoustic lens 6 to rotate.

[0024] The medium drive structure includes a medium sealing ring 501, a sealing convex ring 502, a sealing rubber ring 503, a limiting convex ring 504, a medium connecting pipe 505, a medium pipeline 506, a piston disc 507, a limiting connecting rod 508, a limiting square hole 509, a threaded sleeve 510, a drive screw 511, and a medium motor 512.

[0025] The medium sealing ring 501 is fixedly installed on the outer surface of the fixed acoustic lens 5. A sealing protrusion ring 502 is fixedly provided on the inner surface of the medium sealing ring 501. A sealing rubber ring 503 is fixedly provided on the inner surface of the sealing protrusion ring 502. The sealing rubber ring 503 is in sealing contact with the outer surface of the movable acoustic lens 6.

[0026] A limiting protrusion ring 504 is fixedly provided on the outer surface of the movable acoustic lens 6, near the side where the fixed acoustic lens 5 is located. A medium connecting pipe 505 is fixedly connected to the outer surface of the medium sealing ring 501. A medium pipeline 506 is fixedly connected to the other end of the medium connecting pipe 505. A piston disc 507 is movably provided inside the medium pipeline 506.

[0027] A limiting link 508 is fixedly installed on one side surface of the piston disc 507. A limiting square hole 509 is opened through the end of the medium pipeline 506. The limiting link 508 passes through the limiting square hole 509 and can only move axially within the limiting square hole 509, but cannot rotate.

[0028] A threaded sleeve 510 is fixedly provided at the end of the limiting link 508. A drive screw 511 is spirally provided inside the threaded sleeve 510. The drive screw 511 is connected to the medium motor 512 for transmission. The medium motor 512 is fixedly installed with the outer ring shell 1.

[0029] The rotary drive structure includes a rotary convex ring 513, a driven gear ring 514, a drive shaft gear 515, and a drive motor 516.

[0030] The rotating convex ring 513 is fixedly installed on the outer surface of the movable acoustic lens 6. The inner surface of the rotating convex ring 513 is fixedly provided with a driven gear ring 514. The drive shaft gear 515 meshes with the driven gear ring 514. The drive shaft gear 515 is driven by the drive motor 516. The drive motor 516 is fixedly installed with the outer ring shell 1.

[0031] A tailstock portion 101 is fixedly provided on one side of the outer shell 1, and a backing plate 201 is fixedly provided inside the inner shell 2 on the side of the piezoelectric ceramic 3 away from the matching layer 4.

[0032] In use, the present invention involves coating the movable acoustic lens 6 or the skin surface with coupling fluid, driving the motor 516 to run, and driving the movable acoustic lens 6 to rotate through the meshing of the drive shaft gear 515 and the driven gear ring 514. This allows the movable acoustic lens 6 to evenly disperse the coupling fluid between the movable acoustic lens 6 and the skin when it comes into contact with the skin, thereby improving the detection effect.

[0033] The space between the fixed acoustic lens 5 and the movable acoustic lens 6 is sealed with a coupling fluid or other medium liquid, which eliminates the gap between them and avoids obstructing ultrasonic refraction. When the medium motor 512 drives the drive screw 511 to rotate, the screw threaded sleeve 510 and the drive screw 511 are screwed together to push the piston disc 507 to move axially. During the axial movement of the piston disc 507, the medium liquid in the medium pipe 506 interacts with the medium liquid between the fixed acoustic lens 5 and the movable acoustic lens 6 through the medium connecting pipe 505. When the medium liquid between the fixed acoustic lens 5 and the movable acoustic lens 6 increases, the movable acoustic lens 6 is pushed outward. When the medium liquid between the fixed acoustic lens 5 and the movable acoustic lens 6 decreases, the movable acoustic lens 6 moves inward. This changes the distance between the movable acoustic lens 6 and the piezoelectric ceramic 3, thereby changing the focus of the ultrasonic wave emitted by the piezoelectric ceramic 3 and achieving flexible adjustment.

[0034] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
