Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, in particular to a medical ultrasonic probe. Background Art

[0002] In the medical field, ultrasonic probes are widely used, and ultrasonic coupling agent needs to be applied when ultrasonic probes are used for detection. Ultrasonic coupling agent is a water-based preparation, which is mainly used to fill the tiny gap between the probe and the skin to ensure that the ultrasonic wave can effectively penetrate the tissue to obtain a clear image. The main function of the ultrasonic coupling agent is to isolate the air between the probe and the skin, reduce the acoustic impedance difference between the sound wave passing through the probe and the skin, and thus make the imaging of the organs better. The coupling agent commonly used in clinical practice is a sterile coupling agent, which has a wide range of applications, is non-toxic, non-irritating, and harmless to the human body. In the existing ultrasonic detection process, the doctor generally applies the coupling agent to the patient's part that needs to be detected, and then uses the detector for detection. The ultrasonic detector itself does not have the function of applying, which makes the equipment more troublesome and inefficient during detection, and requires the doctor to perform multiple steps, which affects the efficiency of the detection.

[0003] Based on this, the present invention designs a medical ultrasonic probe to solve the above problems. Summary of the invention

[0004] The object of the present invention is to provide a medical ultrasonic probe to solve the problem mentioned in the above background technology that the existing equipment has certain limitations when used, which affects the detection efficiency.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A medical ultrasonic probe comprises a detection body, an ultrasonic detection head slidably connected to the lower side of the body detection subject, and further comprising:

[0007] An smearing assembly is arranged inside the detection body, and includes two smearing plates arranged at the bottom of the detection body for facilitating the smearing of the coupling agent;

[0008] The alternating component is arranged inside the detection body, drives the ultrasonic detection head to adjust up and down, and drives the smear plate to rotate at the same time, so that the smear plate and the ultrasonic detection head make way.

[0009] Preferably, a slide bar used for guiding the movement of the ultrasonic detection head is fixedly connected to the ultrasonic detection head, and the ultrasonic detection head is located at the bottom of the slide bar.

[0010] Preferably, the alternating component includes, in sequence, a driving shaft rotatably connected to the detection body, two first racks slidably connected to the detection body, a first gear installed on the driving shaft and meshing between the two first racks to move the two first racks, and the sliding rod is fixedly connected to one of the first racks.

[0011] Preferably, the smear component includes, in sequence, a liquid storage chamber for storing coupling agent arranged in the detection body, a liquid catheter for controlling the discharge of the coupling agent, a closing plate for keeping the liquid catheter open and closed, the closing plate is located on the driving shaft, the closing plate is rotatably connected in the liquid catheter, and two delivery tubes for delivering the coupling agent, the other ends of the delivery tubes are connected to the smear plate.

[0012] Preferably, the angle adjustment component is located inside the detection body, and is used for adjusting the angle of the applicator plate when applying, wherein a lower slide is fixedly connected to one of the first racks, and the lower slide is slidably connected in the detection body, and two guide rods for guiding the applicator plate to move downward are fixedly connected to the lower side of the lower slide, and two support rods are fixedly connected to the lower side of the detection body, one end of the applicator plate is rotatably connected to the support rod, a slide groove is provided on the applicator plate, and a slider for rotation adjustment of the applicator plate is provided between the slide groove and the guide rod.

[0013] Preferably, the extrusion assembly is located on both sides of the detection body, and is used to drive the alternating assembly to alternate up and down, and the opening and closing of the smearing assembly, and sequentially includes a second gear installed on the driving shaft, two second racks meshing on the second gear, and extrusion blocks slidably connected to both sides of the detection body.

[0014] Preferably, the second rack is fixedly connected to the extrusion block, and the other end is fixedly connected to a spring, and a limiting telescopic rod for maintaining the spring compression guide is provided on the inner side of the spring.

[0015] Preferably, a rubber anti-slip layer is provided on the surface of the extrusion block, a groove is formed on the side of the detection body, and the extrusion block is located in the groove.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention squeezes two squeezing blocks to make the two squeezing blocks approach each other, and the spring is compressed at the same time. At this time, the second rack drives the second gear to rotate forward. When the second gear rotates forward, the driving shaft and the first gear rotate forward at the same time. When the driving shaft rotates forward, the closing plate rotates forward. At this time, the top surface of the closing plate and the liquid guide tube rotates from a parallel state to a vertical state. At this time, the liquid in the liquid storage chamber passes through the liquid guide tube to the delivery tube, and then is delivered to the smear plate by the delivery tube, so that the bottom of the smear plate is filled with liquid, which is convenient for smearing of the smear plate, reduces the situation of manual secondary smearing, and enables the detection body to also have the smearing function, further improving the smearing efficiency of the device;

[0018] 2. When the guide rod moves downward, the applicator plate rotates with the support rod as the fulcrum, and then the two applicator plates gradually rotate and become parallel to the bottom of the detection body. At this time, the detection body can be moved to apply the coupling agent to the patient's skin surface, making it more convenient to apply. The upward movement of the ultrasonic detection head can separate it from the applicator plate, thereby preventing the ultrasonic detection head from blocking the applicator plate from applying the coupling agent.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-Figure 6 , the present invention provides a technical solution:

[0030] A medical ultrasonic probe comprises a detection body 1, an ultrasonic detection head 2 slidably connected to the lower side of the detection body, and further comprises:

[0031] The smearing assembly is arranged inside the detection body 1, and includes two smearing plates 3 arranged at the bottom of the detection body 1 for facilitating the smearing of the coupling agent;

[0032] The alternating component is arranged inside the detection body 1, drives the ultrasonic detection head 2 to adjust up and down, and drives the smear plate 3 to rotate, so that the smear plate 3 and the ultrasonic detection head 2 form a gap;

[0033] When working, Figure 2 In the initial state of the equipment, the two smear plates 3 are located on both sides of the ultrasonic detection head 2, and the ultrasonic detection head 2 is located at the lower side of the two smear plates 3. At this time, the two smear plates 3 are offset at a certain angle.

[0034] The ultrasonic detection head 2 is fixedly connected with a slide bar 7 for guiding the movement of the ultrasonic detection head 2, and the ultrasonic detection head 2 is located at the bottom of the slide bar 7;

[0035] When working, Figure 3 It is convenient to control the ultrasonic detection head 2 to rise and fall, so as to effectively apply the coupling liquid and detect the applied part, further improving the convenience of using the equipment.

[0036] The alternating assembly includes, in sequence, a driving shaft 4 rotatably connected to the detection body 1, two first racks 6 slidably connected to the detection body 1, a first gear 5 mounted on the driving shaft 4 and meshed between the two first racks 6 to move the two first racks 6, and a slide bar 7 fixedly connected to one of the first racks 6;

[0037] When working, Figure 4 When the driving shaft 4 rotates in the forward direction, the first gear 5 can be controlled to rotate in the forward direction, so that the two first racks 6 move up and down. Figure 6 At the same time, the driving shaft 4 controls the closing plate 15 to rotate, so that the liquid guide tube 14 is opened or closed, thereby ensuring the discharge of the coupling liquid and avoiding the waste of liquid during application.

[0038] The smearing assembly includes, in sequence, a liquid storage chamber 13 for storing coupling agent provided in the detection body 1, a liquid guide tube 14 for controlling the discharge of the coupling agent, a closing plate 15 for keeping the liquid guide tube 14 open and closed, the closing plate 15 being located on the driving shaft 4 and rotatably connected to the liquid guide tube 14, and two delivery tubes 16 for delivering the coupling agent, the other end of the delivery tube 16 being connected to the smearing plate 3;

[0039] When working, Figure 6 When the driving shaft 4 rotates forward, the closing plate 15 rotates. At this time, a gap is formed between the closing plate 15 and the liquid guide tube 14, and the liquid enters the delivery tube 16 through the gap, and then enters the smearing plate 3 from the delivery tube 16, thereby completing the smearing of the liquid. Similarly, when the driving shaft 4 rotates reversely, the closing plate 15 closes the liquid guide tube 14, thereby preventing the liquid from being discharged from the liquid guide tube 14, and avoiding liquid leakage when the equipment is using the ultrasonic detection head 2 for detection, thereby resulting in waste of coupling liquid.

[0040] Among them, the angle adjustment component is located inside the detection body 1, and is used to adjust the angle of the smear plate 3 when smearing, and a lower slide plate 8 is fixedly connected to one of the first racks 6, and the lower slide plate 8 is slidably connected in the detection body 1, and two guide rods 9 for guiding the smear plate 3 to move downward are fixedly connected to the lower side of the lower slide plate 8, and two support rods 10 are fixedly connected to the lower side of the detection body 1. One end of the smear plate 3 is rotatably connected to the support rod 10, and a slide groove 11 is provided on the smear plate 3. A slider 12 for rotating and adjusting the smear plate 3 is provided between the slide groove 11 and the guide rod 9;

[0041] When working, Figure 5When the lower slide plate 8 is squeezed and moved downward by the first rack 6, the guide rod 9 moves downward at the same time. At this time, the guide rod 9 pushes the applicator plate 3 downward to rotate with the support rod 10 as the fulcrum. As the applicator plate 3 rotates, the slider 12 gradually moves in the slide groove 11 until the applicator plate 3 and the lower slide plate 8 are parallel. At this time, the applicator plate 3 can be used to apply the application to the patient, and the ultrasonic detector is located on the upper side of the applicator plate 3, so as to avoid interference with it during application.

[0042] Among them, the extrusion assembly is located on both sides of the detection body 1, and is used to drive the alternating assembly to alternate up and down, and the opening and closing of the smearing assembly, and sequentially includes a second gear 17 installed on the driving shaft 4, two second racks 18 meshing on the second gear 17, and an extrusion block 19 slidably connected to both sides of the detection body 1;

[0043] When working, Figure 3 , pushing the two extrusion blocks 19 closer to each other, at this time the second rack 18 pushes the second gear 17 to rotate forward, so that the drive shaft 4 rotates forward, at this time the spring 20 is squeezed and is in a compressed state, when the drive shaft 4 rotates forward, the coating assembly and the angle adjustment assembly both work, when the equipment is finished coating, release the extrusion block 19, at this time the spring 20 is compressed and reset to stretch, and then the two extrusion blocks 19 are moved away from each other, and at the same time the drive shaft 4 rotates in the opposite direction, so that the coating plate 3 is tilted at a certain angle again, and the ultrasonic detector is located on the lower side of the coating plate 3, so as to perform sufficient ultrasonic detection.

[0044] The second rack 18 is fixedly connected to the extrusion block 19, and the other end is fixedly connected to the spring 20. The inner side of the spring 20 is provided with a limiting telescopic rod for keeping the spring 20 compressed and guided;

[0045] When working, Figure 3 The limiting telescopic rod inside the spring 20 can effectively ensure the compression direction of the spring 20, avoiding the spring 20 from being in a tilted state when compressed, thereby affecting the movement of the second rack 18 and further improving the stability of the device.

[0046] The surface of the extrusion block 19 is provided with a rubber anti-slip layer, and a groove is formed on the side of the detection body 1, and the extrusion block 19 is located in the groove;

[0047] During operation, the grooves make it easier to store the two extrusion blocks 19 when they are moved, and the rubber anti-skid layer further increases the friction between the device and the operator, making the device more convenient and stable when in use.

[0048] Working principle: When the device is working, Figure 3, squeeze the two squeezing blocks 19, so that the two squeezing blocks 19 are close to each other, and the spring 20 is compressed at the same time. At this time, the second rack 18 drives the second gear 17 to rotate forward. When the second gear 17 rotates forward, the drive shaft 4 and the first gear 5 rotate forward at the same time. When the drive shaft 4 rotates forward, Figure 6 , the closing plate 15 rotates forward, and the closing plate 15 and the top surface of the liquid guide tube 14 rotate from a parallel state to a vertical state. At this time, the liquid in the liquid storage chamber 13 flows into the delivery tube 16 through the liquid guide tube 14. Figure 3 Then it is transported to the smear plate 3 by the delivery pipe 16, so that the bottom of the smear plate 3 is filled with liquid, which facilitates the smearing of the smear plate 3, reduces the situation of manual secondary smearing, and makes the detection body 1 also have the smearing function, further improving the smearing efficiency of the equipment. When the smear plate 3 is filled with liquid;

[0049] The two first racks 6 are driven by the first gear 5 to move up and down alternately. Figure 4 When the first gear 5 rotates forward, the first rack 6 on the right side moves up, and then drives the sliding rod 7 to move up, so that the ultrasonic detection head 2 moves up. At the same time, the first rack 6 on the left side moves down, and then the guide rod 9 moves down. When the guide rod 9 moves down, the smear plate 3 rotates with the support rod 10 as a fulcrum, and then the two smear plates 3 gradually rotate and are parallel to the bottom of the detection body 1. At this time, the detection body 1 can be moved to apply the patient's skin surface, so that it is more convenient to apply. The upward movement of the ultrasonic detection head 2 can separate from the smear plate 3, so as to avoid the ultrasonic detection head 2 blocking the smear plate 3 from applying the coupling agent. When the smear plate 3 is applied, Figure 3 , release the two squeezing blocks 19, the elastic force of the spring 20 is compressed and reset, the two squeezing blocks 19 move outwards, and the second rack 18 controls the second gear 17 to rotate in the opposite direction, and then the driving shaft 4 rotates in the opposite direction, and the first gear 5 drives the two first racks 6 to move again, at this time Figure 4 The first rack 6 on the left side of the middle portion descends, and the first rack 6 on the right side ascends, so that the ultrasonic detection head 2 can detect the patient, thereby further improving the quality and efficiency of its detection.
