Description

Technical Field

[0001] This utility model relates to the field of ultrasonic probe technology, and in particular to a positioning device for an ultrasonic probe. Background Technology

[0002] In recent years, the widespread use of medical ultrasound detectors in clinical practice has made ultrasound-guided interventional procedures increasingly common, such as arteriovenous puncture and ultrasound-guided ablation therapy for tumors. This requires operators to have excellent ultrasound skills and clinical operation capabilities.

[0003] However, the ultrasonic probes in the related technologies still have shortcomings in use. It is inconvenient to effectively install and position the ultrasonic probe, which reduces the accuracy of ultrasonic detection. Furthermore, it is inconvenient to adjust and position the ultrasonic probe according to different target locations, which reduces its practicality. Therefore, we propose an ultrasonic probe positioning device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings by providing a positioning device for an ultrasonic probe.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An ultrasound probe positioning device includes a frame and an ultrasound probe body. A frame is slidably mounted on the top of the frame. A front-to-back positioning mechanism for positioning the ultrasound probe body is provided between the frame and the frame. A sliding sleeve is slidably mounted on the frame. A left-to-right positioning mechanism is provided between the sliding sleeve and the frame. A positioning frame is fixedly connected to the bottom of the sliding sleeve. An angle positioning mechanism is provided between the positioning frame and the ultrasound probe body. Four medical suction cups for fixing the frame to the patient's body surface are fixedly connected to the bottom of the frame.

[0007] As a preferred embodiment of this utility model, the top of the frame has two sliding grooves. The front and rear positioning mechanism includes a guide rod fixedly connected to the inner wall of the front and rear sides of the sliding groove, and a slider slidably sleeved on the outside of the guide rod. The slider and the side of the frame that are close to each other have the same groove. Two springs are fixedly connected to the top inner wall of the groove. The bottom ends of the two springs are fixedly connected to the same lifting plate. The bottom of the lifting plate is fixedly connected to a vertical rod. The bottom of the vertical rod is fixedly connected to a brake pad. The brake pad movably abuts against the outside of the guide rod.

[0008] As a preferred embodiment of this utility model, the frame has mounting openings on both sides, and a rotating shaft is rotatably connected to the inner wall of the front and rear sides of the mounting opening. A rotating plate is fixedly sleeved on the outer side of the rotating shaft, and the rotating plate is movably abutting against the bottom of the lifting plate.

[0009] In a preferred embodiment of this invention, both the lifting plate and the brake pad are slidably fitted into the groove.

[0010] As a preferred embodiment of this utility model, the left and right positioning mechanism includes two screws and a handle. The sliding sleeve is slidably mounted on the outside of the frame. Both screws are threadedly connected to the top of the sliding sleeve, and the bottom ends of both screws are movably abutting against the top of the frame. The handle is fixedly connected to the top of the sliding sleeve.

[0011] In a preferred embodiment of this invention, the positioning frame has a cavity, and the angle positioning mechanism includes a rotating shaft rotatably connected to the inner walls of the front and rear sides of the positioning frame and a second spring fixedly connected to the inner wall of the top of the cavity. A connecting plate is fixedly sleeved on the outer side of the rotating shaft, and the ultrasonic probe body is detachably fixedly connected to the bottom of the connecting plate. External teeth are provided on the outer top of the connecting plate. A movable plate is fixedly connected to the bottom of the second spring, and a support rod is fixedly connected to the bottom of the movable plate. An arc-shaped internal toothed ring is fixedly connected to the bottom of the support rod, and the arc-shaped internal toothed ring meshes with the external teeth. A pull plate is fixedly connected to one side of the movable plate.

[0012] As a preferred embodiment of this utility model, a rectangular opening is provided on one side of the positioning frame, the pull plate is slidably sleeved in the rectangular opening, and the moving plate is slidably sleeved in the cavity.

[0013] As a preferred embodiment of this utility model, a fixing plate is fixedly connected to the bottom of the connecting plate, and two fixing screws are threadedly connected to the top of the fixing plate. The ultrasonic probe body is fixedly connected to the bottom of the fixing plate by the two fixing screws.

[0014] In this invention, the positioning device for an ultrasonic probe involves pressing down two rotating plates to adjust the position to be detected. The inner sides of the rotating plates deflect upwards, causing a lifting plate to move upwards and compress a spring. The lifting plate then moves the vertical rod and brake pad upwards, preventing them from contacting the guide rod and thus not fixing the slider to the frame. At this point, the frame and the ultrasonic probe body can be adjusted to move back and forth according to the desired detection position, aligning the desired detection position with the ultrasonic probe body. Once adjusted, the rotating plates are released, and the spring force of the first spring... The downward movement of the lifting plate and brake pads will cause them to move downward and firmly abut against the outside of the guide rod, thereby fixing the frame and slider and improving the stability after front and rear positioning. The rotating plate will rotate and reset as the lifting plate moves downward. According to the left and right position of the detection, loosen the two screws so that they are not abutting against the top of the frame. Pull the handle to move the sliding sleeve and the ultrasonic probe body to align the left and right position to be detected with the ultrasonic probe body. Then tighten the two screws so that the bottom of the two screws firmly abuts against the top of the frame, thereby locking the sliding sleeve.

[0015] In this invention, an ultrasonic probe positioning device allows for the upward pulling of a pull plate according to the required detection angle. The pull plate causes a moving plate to move upward and compress a spring. The moving plate then causes a support rod and an arc-shaped inner toothed ring to move upward without engaging with the outer teeth, thus not restricting or fixing the connecting plate. The connecting plate and the ultrasonic probe body are rotated around a rotating shaft, allowing for adjustment and positioning of the detection angle. After adjustment, the pull plate is released. Under the elastic force of the spring, the arc-shaped inner toothed ring moves downward and firmly abuts against the outside of the outer teeth, thus fixing the connecting plate and the ultrasonic probe body. This positioning device helps medical personnel to position and fix the ultrasonic probe body at any angle and position, facilitating long-term clinical monitoring of patients and improving the effectiveness of its use.

[0016] This utility model has a reasonable structural design. Through this positioning device, medical personnel can fix the ultrasound probe body at any angle and position, so as to help clinical long-term detection and monitoring of patients, improve the effectiveness and versatility of use, and have high reliability.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-4 An ultrasonic probe positioning device includes a frame 2 and an ultrasonic probe body 7. The ultrasonic probe body 7 is a medical ultrasonic probe, which is a device for emitting and receiving ultrasonic waves during ultrasonic detection. The performance of the probe directly affects the characteristics of ultrasonic waves and the detection performance of ultrasonic waves. The probe used in ultrasonic detection is a transducer that uses the piezoelectric effect of materials to realize the conversion of electrical energy and acoustic energy. The key component in the probe is the crystal, which is a single crystal or polycrystalline thin film with piezoelectric effect. Its function is to convert electrical energy and acoustic energy into each other.

[0024] A frame 3 is slidably mounted on the top of the frame 2. A front-to-back positioning mechanism 4 for positioning the ultrasound probe body 7 is provided between the frame 3 and the frame 2. A sliding sleeve 51 is slidably mounted on the frame 3. A left-to-right positioning mechanism 5 is provided between the sliding sleeve 51 and the frame 3. A positioning frame 601 is fixedly connected to the bottom of the sliding sleeve 51. An angle positioning mechanism 6 is provided between the positioning frame 601 and the ultrasound probe body 7. Four medical suction cups 1 for fixing the frame 2 to the patient's body surface are fixedly connected to the bottom of the frame 2.

[0025] Specifically, refer to Figure 1 and Figure 3 As shown, the top of the frame 2 has two sliding grooves 401. The front and rear positioning mechanism 4 includes a guide rod 403 fixedly connected to the inner wall of the front and rear sides of the sliding groove 401, and a slider 402 slidably sleeved on the outside of the guide rod 403. The slider 402 and the side of the frame 3 that are close to each other have the same groove 405. Two springs 406 are fixedly connected to the top inner wall of the groove 405. The bottom ends of the two springs 406 are fixedly connected to the same lifting plate 407. The bottom of the lifting plate 407... A vertical rod 408 is fixedly connected to the top of the frame 3. A brake pad 409 is fixedly connected to the bottom of the vertical rod 408. The brake pad 409 is movably abutted against the outside of the guide rod 403. Mounting ports 410 are provided on both sides of the frame 3. A rotating shaft 411 is rotatably connected to the inner wall of the front and rear sides of the mounting port 410. A rotating plate 404 is fixedly sleeved on the outside of the rotating shaft 411. The rotating plate 404 is movably abutted against the bottom of the lifting plate 407. The lifting plate 407 and the brake pad 409 are both slidably sleeved in the groove 405.

[0026] Using the above scheme: Based on the required front-to-back position, press down on the two rotating plates 404. The inner side of the rotating plates 404 deflects upward, causing the lifting plate 407 to move upward and compress the spring 406. The lifting plate 407 causes the vertical rod 408 and brake pad 409 to move upward, preventing them from contacting the guide rod 403. Therefore, the slider 402 and the frame 3 are not fixed. At this point, the frame 3 and the ultrasonic probe body 7 can be moved forward and backward according to the required front-to-back position, aligning the required front-to-back position with the ultrasonic probe body 7. After adjustment, release the rotating plates 404. Under the elastic force of the spring 406, the lifting plate 407 and brake pad 409 will move downward and firmly contact the outer side of the guide rod 403, thus fixing the frame 3 and the slider 402 and improving stability after front-to-back positioning. The rotating plates 404 rotate back to their original position as the lifting plate 407 moves downward.

[0027] Specifically, refer to Figure 1 and Figure 4 As shown, the left and right positioning mechanism 5 includes two screws 52 and a handle 53. The sliding sleeve 51 is slidably mounted on the outside of the frame 3. The two screws 52 are threadedly connected to the top of the sliding sleeve 51, and the bottom ends of the two screws 52 are movably abutting against the top of the frame 3. The handle 53 is fixedly connected to the top of the sliding sleeve 51.

[0028] Using the above method: Based on the left and right position to be detected, loosen the two screws 52 so that the two screws 52 do not abut against the top of the frame 3. Pull the sliding sleeve 51 and the ultrasonic probe body 7 by the handle 53 so that the left and right position to be detected is aligned with the ultrasonic probe body 7. Then tighten the two screws 52 so that the bottom ends of the two screws 52 are firmly abut against the top of the frame 3, thereby locking the sliding sleeve 51.

[0029] Specifically, refer to Figure 1 , Figure 2 and Figure 4As shown, a cavity 609 is provided inside the positioning frame 601. The angle positioning mechanism 6 includes a rotating shaft 603 rotatably connected to the inner walls of the front and rear sides of the positioning frame 601 and a spring 610 fixedly connected to the inner wall of the top of the cavity 609. A connecting plate 604 is fixedly sleeved on the outer side of the rotating shaft 603. The ultrasonic probe body 7 is detachably fixedly connected to the bottom of the connecting plate 604. An external tooth 605 is provided on the outer side of the top of the connecting plate 604. A moving plate 608 is fixedly connected to the bottom of the spring 610. A support rod 606 is fixedly connected to the bottom of the moving plate 608. An arc-shaped internal toothed ring 607 is fixedly connected to the bottom of the support rod 606. The arc-shaped internal toothed ring 607 meshes with the external tooth 605. A pull plate 602 is fixedly connected to one side of the moving plate 608. A rectangular opening 611 is provided on one side of the positioning frame 601. The pull plate 602 is slidably sleeved in the rectangular opening 611. The moving plate 608 is slidably sleeved in the cavity 609.

[0030] Using the above scheme: as needed for the required detection angle, pull plate 602 is pulled upwards. Pull plate 602 drives the moving plate 608 to move upwards and squeeze spring 610. Moving plate 608 drives the support rod 606 and the arc-shaped internal toothed ring 607 to move upwards without contacting or engaging with the external teeth 605, thus not restricting or fixing the connecting plate 604. The connecting plate 604 and the ultrasonic probe body 7 are rotated by the rotating shaft 603, thereby adjusting and positioning the detection angle. After adjustment, pull plate 602 is released. At this time, under the elastic force of spring 610, the arc-shaped internal toothed ring 607 moves downwards and firmly abuts against the outside of the external teeth 605, thereby fixing the connecting plate 604 and the ultrasonic probe body 7.

[0031] Specifically, the bottom of the connecting plate 604 is fixedly connected to a fixing plate 9, and the top of the fixing plate 9 is threadedly connected to two fixing screws 8. The ultrasonic probe body 7 is fixedly connected to the bottom of the fixing plate 9 through the two fixing screws 8, which facilitates the disassembly and assembly of the ultrasonic probe body 7 and facilitates later maintenance.

[0032] In this invention, during use, the ultrasound probe body 7 is installed at the bottom of the connecting plate 604 via a fixing plate 9 and two fixing screws 8. Four medical suction cups 1 are attached, and the frame 2 is installed on the patient's body surface. To determine the desired detection position, the two rotating plates 404 are pressed downwards. The inner side of the rotating plates 404 deflects upwards, causing the lifting plate 407 to move upwards and compress the spring 406. The lifting plate 407 causes the vertical rod 408 and brake pad 409 to move upwards, preventing them from contacting the guide rod 403. Therefore, the slider 402 and the frame 3 are not fixed. At this point, the frame 3 and the ultrasound probe body 7 can be moved back and forth to adjust the desired detection position, aligning the desired detection position with the ultrasound probe body 7. Once adjusted... When the rotating plate 404 is released, the spring force of the spring 406 will cause the lifting plate 407 and the brake pad 409 to move downward and firmly abut against the outside of the guide rod 403, thereby fixing the frame 3 and the slider 402 and improving the stability after front and rear positioning. The rotating plate 404 will rotate and reset as the lifting plate 407 moves downward. According to the left and right position to be detected, loosen the two screws 52 so that the two screws 52 do not abut against the top of the frame 3. Pull the sliding sleeve 51 and the ultrasonic probe body 7 by the handle 53 so that the left and right position to be detected is aligned with the ultrasonic probe body 7. Then tighten the two screws 52 so that the bottom of the two screws 52 firmly abuts against the top of the frame 3, thereby locking the sliding sleeve 51.

[0033] Finally, pull the pull plate 602 upwards according to the required detection angle. The pull plate 602 drives the moving plate 608 upwards and compresses the second spring 610. The moving plate 608 drives the support rod 606 and the arc-shaped internal toothed ring 607 upwards without contacting or engaging with the external teeth 605, thus not restricting or fixing the connecting plate 604. Rotate the connecting plate 604 and the ultrasound probe body 7 with the rotating shaft 603, thereby adjusting and positioning the detection angle. After adjustment, release the pull plate 602. At this time, under the elastic force of the second spring 610, the arc-shaped internal toothed ring 607 moves downwards and firmly abuts against the outside of the external teeth 605, thereby fixing the connecting plate 604 and the ultrasound probe body 7. Thus, through this positioning device, medical personnel can help position and fix the ultrasound probe body 7 at any angle and position, so as to help clinicians monitor patients for a long time and improve the effectiveness of use.
