Abstract
Description
Technical Field
[0001] This utility model relates to the field of ultrasound examination technology, specifically to a probe fixing mechanism for ultrasound examination. Background Technology
[0002] An ultrasonic testing probe is a key device that converts electrical signals into ultrasonic waves based on the piezoelectric effect. It is widely used in industrial testing, medical diagnostics, and materials analysis. The use of a coupling agent in ultrasonic testing is a crucial step in ensuring effective ultrasonic wave propagation and image quality; its function is primarily based on acoustic principles and operational requirements.
[0003] However, after using coupling gel to examine patients, the ultrasound probe becomes contaminated with the gel, which is quite viscous and difficult to wipe clean. This necessitates removing the probe for cleaning. However, existing probes require pulling out the entire cable from the back of the device, sometimes even requiring the device to be moved, which is inconvenient and affects examination efficiency. Therefore, we propose a probe fixing mechanism for ultrasound examinations. Utility Model Content
[0004] The purpose of this utility model is to provide a probe fixing mechanism for ultrasonic examination, which solves the problem that it is very inconvenient to pull out the entire connecting cable from the back of the testing equipment when disassembling the ultrasonic probe.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] An ultrasound probe fixing mechanism includes a probe body and a connecting wire. The probe body is provided with a pin at one end near the connecting wire, and the connecting wire is provided with a socket for the pin to connect at one end near the probe body.
[0007] It also includes a connecting part for quick fixation and replacement of the probe body;
[0008] The control unit is used to allow for quick disassembly of the probe body and to ensure that the replaced probe body can be quickly secured.
[0009] The connecting part includes a retaining ring, which is penetrated by the probe body and fixedly connected to the probe body. The surface of the retaining ring is provided with a fitting groove. One end of the connecting line near the probe body is penetrated and fixedly connected to a connecting plate. A fixing plate is penetrated and fixedly connected to the inner side of the connecting plate. A connecting block is penetrated to the inner side of the fixing plate. The connecting block is slidably connected to the fixing plate. A retaining block is fixedly connected to the side surface of the connecting block near the axis of the connecting plate.
[0010] Preferably, the shape of the fitting groove and the shape of the card block are both trapezoidal, and the card block fits into the fitting groove.
[0011] Preferably, a support rod is fixedly connected to the inner side of the fixed disk, the support rod passes through the connecting block and is slidably connected, and a spring is fixedly connected between the connecting block and the inner side of the fixed disk.
[0012] Preferably, a turntable is rotatably connected through the inner side of the connecting disc, and a transmission groove is formed on the surface of the turntable.
[0013] Preferably, a slide rod is fixedly connected to the surface of the connecting block, and the end of the slide rod away from the connecting block is inserted into the inside of the transmission groove.
[0014] Preferably, the side of the connecting plate is provided with a movable groove, and a lever is fixedly connected to the side of the turntable, the lever passing through the movable groove.
[0015] Preferably, the control unit includes an arc-shaped fixing strip, which is fixedly connected to the surface of the connecting disc. A guide ring is passed through and fixedly connected to the inner side of the arc-shaped fixing strip. The guide ring passes through a paddle. An arc-shaped spring is fixedly connected between the paddle and the surface of the arc-shaped fixing strip.
[0016] By employing the above technical solution, this utility model provides a probe fixing mechanism for ultrasound examination. It possesses at least the following beneficial effects:
[0017] (1) The present invention drives the transmission groove to rotate when the turntable rotates. The transmission groove will then push the slide rod located inside the transmission groove to slide. However, the end of the slide rod away from the transmission groove is fixedly connected to the connecting block, so that the connecting block will be relatively limited and can only slide along the fixed plate. When the slide rod is pushed by the transmission groove, the slide rod will drive the connecting block to gradually slide away from the axis of the connecting plate, thereby causing the connecting block to drive the locking block to slide out of the fitting groove. Then the locking block will no longer limit the locking ring, and the probe body can be directly pulled out, thus achieving the simplest operation and quick fixation and connection of the probe body.
[0018] (2) When the probe body is removed, the compressed arc spring will push the lever to reset along the guide ring, so that the lever can reset the turntable. Similarly, the spring will also push the connecting block to reset the locking block, so that the inclined surface of the locking block can be reset again, which makes it easy to quickly connect and fix the new probe body or the cleaned probe body.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Example 1
[0028] An ultrasound probe fixing mechanism, such as Figures 1-5As shown, the device includes a probe body 1 and a connecting cable 4. A pin 6 is provided at one end of the probe body 1 near the connecting cable 4, and a socket 5 for the pin 6 to connect to is provided at the other end of the connecting cable 4 near the probe body 1. It also includes a connecting part 2 for quick fixing and replacement of the probe body 1; and a control part 3 for quick disassembly of the probe body 1 and ensuring quick fixing of the replaced probe body 1. The connecting part 2 includes a retaining ring 21, which is penetrated by the probe body 1 and fixedly connected to it. A fitting groove 22 is formed on the surface of the retaining ring 21. A connecting plate 23 is passed through and fixedly connected to one end of the connecting cable 4 near the probe body 1, and a fixing plate 23 is passed through and fixedly connected to the inner side of the connecting plate 23. The inner side of the fixed plate 24 is connected by a connecting block 25. The locking block 26 lifts the connecting block 25, causing it to slide along the support rod 27. The connecting block 25 compresses the spring 28. When the retaining ring 21 is fully inserted into the connecting plate 23, the fitting groove 22 and the locking block 26 are aligned. The compressed spring 28 pushes the connecting block 25, causing the locking block 25 to drive the locking block 26 into the fitting groove 22. The right side of the fitting groove 22 is a vertical surface, which is blocked by the vertical surface of the embedded locking block 26, thus limiting the retaining ring 21 and preventing it from being pulled out. The connecting block 25 is slidably connected to the fixed plate 24. The locking block 26 is fixedly connected to the side surface of the connecting block 25 near the axis of the connecting plate 23. Both the fitting groove 22 and the locking block 26 are trapezoidal in shape, and the locking block 26 fits into the fitting groove 22. The connecting end of the probe body 1 is aligned with the connecting end of the connecting line 4, and then the probe body 1 is inserted into the connecting plate 23. The probe body 1 will drive the retaining ring 21 to be inserted into the inner side of the connecting plate 23. Because both the fitting groove 22 and the locking block 26 are trapezoidal, the retaining ring 21 will gradually abut against the inclined surface of the locking block 26 when inserted into the connecting plate 23, thereby forcing the locking block 26 to push up the connecting block 25. A support rod 27 is fixedly connected to the inner side of the fixing plate 24. The support rod 27 passes through the connecting block 25 and is slidably connected. A spring 28 is fixedly connected between the connecting block 25 and the inner side of the fixing plate 24. A turntable 210 is rotatably connected to the inner side of the connecting plate 23. When the turntable 210 rotates, it drives the transmission groove 211 to rotate as well. The transmission groove 211 then moves the slide rod 29, which is inserted into the inner side of the transmission groove 211, to slide. However, the end of the slide rod 29 away from the transmission groove 211 is fixedly connected to the connecting block 25, so that the connecting block 25 is relatively limited and can only slide along the fixed plate 24. The surface of the turntable 210 has a transmission groove 211. The surface of the connecting block 25 is fixedly connected to the slide rod 29, and the end of the slide rod 29 away from the connecting block 25 is inserted into the inner side of the transmission groove 211. The side of the connecting plate 23 has a movable groove 213, and the side of the turntable 210 is fixedly connected to a lever 212, which passes through the movable groove 213.
[0029] In this embodiment, when the turntable 210 rotates, it will drive the transmission groove 211 to rotate as well. The transmission groove 211 will then push the slide rod 29 located inside the transmission groove 211 to slide. However, the end of the slide rod 29 away from the transmission groove 211 is fixedly connected to the connecting block 25, so that the connecting block 25 will be relatively limited and can only slide along the fixed plate 24. Furthermore, when the slide rod 29 is pushed by the transmission groove 211, the slide rod 29 will drive the connecting block 25 to gradually slide in the opposite direction away from the axis of the connecting plate 23, thereby causing the connecting block 25 to drive the locking block 26 to slide out of the fitting groove 22. Then the locking block 26 will no longer limit the locking ring 21, and the probe body 1 can be directly pulled out, thereby achieving the simplest operation and quick fixation and connection of the probe body 1.
[0030] Example 2
[0031] like Figures 4-5 As shown, the control unit 3 includes an arc-shaped fixing strip 31, which is fixedly connected to the surface of the connecting plate 23. A guide ring 32 is passed through and fixedly connected to the inner side of the arc-shaped fixing strip 31. The guide ring 32 passes through the paddle 212. An arc-shaped spring 33 is fixedly connected between the paddle 212 and the surface of the arc-shaped fixing strip 31.
[0032] In this embodiment, when the probe body 1 is removed, the compressed arc spring 33 pushes the paddle 212 to reset along the guide ring 32, so that the paddle 212 moves the turntable 210 to reset. Similarly, the spring 28 also pushes the connecting block 25 to drive the locking block 26 to reset, so that the inclined surface of the locking block 26 is reset again, which facilitates the quick connection and fixation of the new probe body 1 or the cleaned probe body 1.
[0033] In use, the ultrasonic probe fixing mechanism of this utility model first aligns the connecting end of the probe body 1 with the connecting end of the connecting cable 4 during the installation of the probe body 1. Then, the probe body 1 is inserted into the connecting plate 23. The probe body 1 will drive the retaining ring 21 to be inserted into the inner side of the connecting plate 23. Since both the fitting groove 22 and the retaining block 26 are trapezoidal, the retaining ring 21 will gradually abut against the inclined surface of the retaining block 26 when inserted into the connecting plate 23, thereby forcing the retaining block 26 to push up the connecting block 25. This causes the connecting block 25 to slide along the support rod 27, compressing the spring 28. When the retaining ring 21 is fully inserted into the connecting plate 23, the engagement groove 22 and the retaining block 26 are aligned. The compressed spring 28 then pushes the connecting block 25, causing it to drive the retaining block 26 into the engagement groove 22. The right side of the engagement groove 22 is a vertical surface, which is blocked by the vertical surface of the embedded retaining block 26, thus limiting the retaining ring 21 and preventing it from being pulled out. At this time, the pin 6 is also fully inserted into the socket 5. When the probe body 1 needs to be disassembled, cleaned, or replaced due to the contact with coupling agent during testing, the lever 212 can be moved to slide within the movable groove 213. When the lever 212 is moved, it slides along the guide ring 32, compressing the arc spring 33. Simultaneously, the lever 212 drives the turntable 210 to rotate. As the turntable 210 rotates, it also drives the transmission groove 211 to rotate. The transmission groove 211 then moves the probe body 213. The inner slide bar 29 slides, but the end of the slide bar 29 away from the transmission groove 211 is fixedly connected to the connecting block 25, so that the connecting block 25 is relatively limited and can only slide along the fixed plate 24. When the slide bar 29 is pushed by the transmission groove 211, the slide bar 29 will drive the connecting block 25 to gradually slide in the opposite direction away from the axis of the connecting plate 23, thereby causing the connecting block 25 to drive the locking block 26 to slide out of the fitting groove 22. Then the locking block 26 will no longer limit the locking ring 21, and the probe body 1 can be directly pulled out.
[0034] When the probe body 1 is removed, the compressed arc spring 33 pushes the lever 212 to reset along the guide ring 32, causing the lever 212 to reset the turntable 210. Similarly, the spring 28 also pushes the connecting block 25 to reset the locking block 26, causing the inclined surface of the locking block 26 to reset again, which facilitates the quick connection and fixation of the new probe body 1 or the cleaned probe body 1.
