Description

Technical Field

[0001] The invention relates to the technical field of ultrasonic detection auxiliary equipment, in particular to ultrasonic medical auxiliary detection equipment. Background Art

[0002] Medical ultrasonic testing equipment is an instrument that uses ultrasonic technology to perform medical imaging examinations, mainly used to diagnose and monitor various diseases. The equipment transmits high-frequency sound waves into the body, and the sound waves are reflected when they encounter different tissues and organs. The equipment receives these reflected waves and converts them into images. Medical ultrasonic testing equipment is widely used in prenatal examinations for pregnant women, heart disease detection, abdominal organ examinations and other fields. It can provide clear images of internal structures in real time to help doctors make accurate diagnoses and treatments. Due to its non-invasive and radiation-free characteristics, ultrasonic testing is considered a safe and effective medical imaging technology.

[0003] A Chinese patent discloses a high-stability ultrasonic image processing probe (authorization announcement number CN114668418B). The patent can achieve different usage effects according to the degree of wrinkles of the skin of the observed area according to the needs, and cooperate with the forward and reverse rotation of the forward and reverse motor. When observing on relatively flat skin, the forward and reverse rotation of the forward and reverse motor is used to drive the liquid homogenizing cylinder to rotate outward, which can reduce to a certain extent the effect of the ultrasonic probe moving, which causes the coupling agent to be evenly spread, resulting in poor contact between the coupling agent and the ultrasonic probe and the generation of air, causing unclear images. When observing on relatively wrinkled skin, the reverse rotation of the forward and reverse motor is used to drive the liquid homogenizing cylinder to rotate inward, so as to improve the flatness of the skin directly below the ultrasonic probe, reduce the gap between the wrinkled skin and the ultrasonic probe, and make the coupling agent better contact with the ultrasonic probe, thereby improving the clarity of the ultrasonic image to a certain extent.

[0004] In the above patent, the problem that the ultrasonic probe generates air due to poor contact between the coupling agent and the ultrasonic probe due to the coupling agent being evenly distributed is solved, resulting in unclear images. However, the contact area between the ultrasonic probe and the skin is large. During the detection process of the ultrasonic probe, the contact area may not be flat, which may cause the liquid distribution tube to fail to fully contact the skin, thereby reducing the spreading effect of the coupling agent. In addition, there are gaps between the liquid distribution tubes, which may cause the coupling agent to be missed. For this reason, the applicant proposes an ultrasonic medical auxiliary detection device. Summary of the invention

[0039] 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.

[0040] Example 1: Please refer to Figures 1 to 6In an embodiment of the present invention, an ultrasonic medical auxiliary detection device includes a scraper assembly 1, the scraper assembly 1 includes an ultrasonic probe 101, the lower end of the ultrasonic probe 101 is rotatably connected to a rotating sleeve 102 through a bearing, the ultrasonic probe 101 is composed of a probe housing and a probe detection component assembly, the structure and principle of the ultrasonic probe 101 are all prior art, and are not repeated here, the inner side wall of the housing of the ultrasonic probe 101 is fixedly connected to a fixing plate 103, the upper side wall of the fixing plate 103 is fixedly connected to a motor 104 through bolts, the lower side wall of the fixing plate 103 is rotatably connected to a gear 105 fixedly connected to the output end of the motor 104, the inner side wall of the rotating sleeve 102 is fixedly connected to a tooth surface 106 meshing with the gear 105, and the tooth surface 106 is annularly distributed, the rotating sleeve 102 is rotatably connected to a guide tube 2 through two bearings fixed at its upper and lower ends, and the guide tube 2 is hinged with a plurality of skin support components 3 for scraping the coupling agent through a hinge component 4;

[0041] The hinge assembly 4 includes a fixed block 401 fixedly connected to the fixed shell 301 in the skin support assembly 3, and the left and right side walls of the fixed block 401 are rotatably connected to the hinge plate 402 fixedly connected to the guide tube 2 through bearings. A torsion spring 403 is fixedly connected between the fixed block 401 and the hinge plate 402. In the initial state, the skin support assembly 3 is set downward under the action of the torsion spring 403. When in use, the medical staff starts the motor 104, and the motor 104 drives the gear 105 to rotate, so that the gear 105 drives the rotating sleeve 102 to rotate through the tooth surface 106. The rotating sleeve 102 drives the guide tube 2 to rotate through the friction force with the airbag 704. The guide tube 2 drives the skin support assembly 3 to rotate through the hinge assembly 4. The skin support assembly 3 scrapes the coupling agent to the center through the straw 304 to prevent the coupling agent from being evenly spread and thinned, resulting in a gap between the ultrasonic probe 101 and the skin, resulting in unclear detection images.

[0042] The skin support component 3 includes a fixed shell 301, and two pulleys 302 are rotatably connected between the inner walls of the upper and lower sides of the fixed shell 301. The same belt 303 is sleeved between the two pulleys 302. A suction pipe 304 is rotatably connected to the lower side wall of the fixed shell 301, and the suction pipe 304 passes through the fixed shell 301 and is connected to one of the pulleys 302 and fixedly connected. The suction pipe 304 is an L-shaped structure, and the suction pipe 304 is an arc-shaped structure when viewed from above, so that the coupling agent can be better guided to the center, and a plurality of evenly distributed suction holes are drilled on the lower side wall of the suction pipe 304, through which the suction holes enable the suction pipe 304 to generate suction. The interior of the pulley 302 is a hollow structure, and the suction pipe 304 is L-shaped. An arc-shaped scraper 305 is fixedly connected to the side wall of 04, a magnetic component 5 fixedly connected to the belt 303 for driving the belt 303 to move is slidably connected to the side wall of the fixed shell 301, and a guide component 6 for increasing the friction between the straw 304 and the skin is fixedly connected to the upper side wall of the fixed shell 301. When the magnetic component 5 moves, it will drive the belt 303 to move together, and the belt 303 will drive the two pulleys 302 to rotate, one of the pulleys 302 can drive the straw 304 to rotate a certain angle, so as to effectively pull the skin when facing skin with many wrinkles, make the skin flatter, and reduce the burden of medical staff's inspection.

[0043] The magnetic assembly 5 includes a moving box 501 fixedly connected to the belt 303, and the moving box 501 is slidably connected to the fixed shell 301 through a slide groove bored in the fixed shell 301, and two limit plates 502 respectively located on the upper and lower sides of the moving box 501 are fixedly connected to the fixed shell 301 by welding, and the upper and lower side walls of the moving box 501 are both plugged with a clamping block 503 that penetrates the limit plate 502, and the ends of the two clamping blocks 503 that are away from each other are both bevel structures, and the limit plate 502 is bored with a clamping block 503 that is connected to the limit plate 502. The two blocks 503 are fixedly connected to a socket matching the block 503, and the limit plate 502 is rotatably connected to a roller for reducing the friction resistance of the block 503. The opposite ends of the two blocks 503 are fixedly connected to a spring plate 504 located inside the mobile box 501. A tension spring 505 for resetting the block 503 is fixedly connected between the spring plate 504 and the mobile box 501. A winding rod 506 is fixedly connected inside the mobile box 501. A magnetic block 507 is slidably connected inside the mobile box 501. The magnetic block 507 and the spring spring 505 are fixedly connected to each other. A pull rope 508 is fixedly connected between the spring plates 504, and the pull rope 508 is arranged around the winding rod 506. An electromagnet 8 magnetically connected to the magnetic block 507 is fixedly connected to the side wall of the rotating sleeve 102 by means of inlay. In the process of rotation of the guide tube 2, in order to prevent the angle of the straw 304 from changing when scraping the skin, in the initial state, the block 503 in the magnetic moving assembly 5 is inserted into the limit plate 502 to lock the position of the moving box 501, thereby preventing the moving box 501 from moving. When the electromagnet 8 is started, the magnetic force generated by the electromagnet 8 will attract the magnetic block 507 to move, so that the magnetic block 507 pulls the card block 503 through the pull rope 508, so that the card block 503 is separated from the limit plate 502, and then continues to move under the magnetic attraction of the electromagnet 8, thereby driving the belt 303 to move. When the electromagnet 8 generates a repulsive force, it will drive the mobile box 501 to reset through the magnetic block 507, so that the card block 503 can be reinserted into the limit plate 502, thereby locking the mobile box 501.

[0044] Example 2: Please refer to Figures 7 and 8Based on Example 1, the guide assembly 6 includes a fixed cylinder 601 fixedly connected to the upper side wall of the fixed shell 301, a movable plug 602 is slidably connected inside the fixed cylinder 601, a circular plate 603 located at the lower side of the movable plug 602 is fixedly connected inside the fixed cylinder 601, a plurality of vent holes are drilled on the side wall of the fixed cylinder 601 and the circular plate 603, so that the movable plug 602 and the piston 701 will not be unable to move due to the air pressure, a limiting hole matching the hexagonal rod 604 is drilled on the circular plate 603, a hexagonal rod 604 arranged through the limiting hole in the circular plate 603 is fixedly connected to the lower side wall of the movable plug 602, a guide cylinder 605 rotatably connected to the fixed shell 301 through a mechanical seal is connected to the upper end of one of the pulleys 302, the guide cylinder 605 is connected to the suction pipe 304 through the pulley 302, and the inner wall of the guide cylinder 605 is drilled The guide groove 606 has a short rod 607 fixedly connected to the hexagonal rod 604 inside which is slidably connected, and the fixed cylinder 601 has an annular plate 608 fixedly connected to the upper side of the movable plug 602, and a return spring 609 fixedly connected between the annular plate 608 and the movable plug 602. When the pulley 302 rotates, the pulley 302 will also drive the guide cylinder 605 to rotate, and the guide cylinder 605 drives the short rod 607 to move upward through the guide groove 606, thereby driving the movable plug 602 to move upward. When the movable plug 602 moves upward, the air inside the pulley 302 and the straw 304 will be sucked, so that the straw 304 generates an adsorption force at this time, which can not only absorb part of the coupling agent and reduce the lubricating effect of the coupling agent, but also increase the friction between the straw 304 and the skin, so that the straw 304 can easily pull the wrinkled skin.

[0045] The upper end of the fixed cylinder 601 is fixedly connected with a stop assembly 7, which includes a piston 701 slidably connected to the inside of the fixed cylinder 601, and the piston 701 is magnetically attracted to the movable plug 602. A connecting spring 702 is fixedly connected between the piston 701 and the upper inner wall of the fixed cylinder 601, and a connecting tube 703 is fixedly connected between the upper end of the fixed cylinder 601 and the guide tube 2. The inner wall of the guide tube 2 is fixedly connected with an air bag 704 connected to the connecting tube 703. Because the piston 701 transmits air to the The airbag 704 is in an expanded state in the initial state. After the movable plug 602 moves up, it will enter the magnetic induction range of the piston 701, and then suck the piston 701 to move downward, so that the air inside the airbag 704 is sucked to the upper end of the fixed cylinder 601. At this time, the airbag 704 is no longer in an expanded state. Therefore, the rotating sleeve 102 cannot drive the guide tube 2 to rotate through the airbag 704, and finally the straw 304 stops rotating, thereby preventing the straw 304 from having a good pulling effect on the wrinkled skin after rotation.

[0046] The working principle of the present invention is:

[0047] When the present invention is used, the medical staff first applies an appropriate amount of coupling agent to the skin to be tested, and then fits the ultrasonic probe 101 to the skin to be tested to observe the part. While the medical staff continuously moves the ultrasonic probe 101, the medical staff starts the motor 104, thereby driving the skin support component 3 to rotate. During the rotation process, the skin support component 3 scrapes the coupling agent to the center through the straw 304 to prevent the coupling agent from being evenly spread and thinned, resulting in a gap between the ultrasonic probe 101 and the skin, resulting in unclear detection images.

[0048] During the detection of uneven parts, the fixed shell 301 always has a downward rotation force due to the torsion of the torsion spring 403. The medical staff only needs to make the bottom of the ultrasonic probe 101 always fit the skin, and the suction tube 304 is squeezed by the uneven parts, so that the suction tube 304 always fits the skin, thereby improving the scraping effect of the coupling agent.

[0049] When the area to be inspected by the medical staff is a relatively wrinkled skin, the medical staff activates the electromagnet 8, and the magnetic force generated by the electromagnet 8 attracts the magnetic block 507 to move, so that the magnetic block 507 pulls the clamping block 503 through the pulley 508, so that the clamping block 503 is separated from the limit plate 502, and then continues to move under the magnetic attraction of the electromagnet 8, thereby driving the belt 303 to move, and the belt 303 drives the two pulleys 302 to rotate, one of which can drive the straw 304 to rotate a certain angle, so that when facing the skin with more wrinkles, it can effectively pull the skin, make the skin flatter, and reduce the burden of medical staff's inspection;

[0050] When the pulley 302 rotates, the pulley 302 also drives the guide cylinder 605 to rotate. The guide cylinder 605 drives the short rod 607 to move upward through the guide groove 606, and then drives the movable plug 602 to move upward, so that the suction tube 304 generates suction force, which can not only absorb part of the coupling agent and reduce the lubrication effect of the coupling agent, but also increase the friction between the suction tube 304 and the skin, and improve the pulling effect of the suction tube 304 on the wrinkled skin;

[0051] When the movable plug 602 moves upward, the piston 701 is also sucked downward, so that the airbag 704 is no longer in an expanded state. Therefore, the rotating sleeve 102 cannot drive the guide tube 2 to rotate through the airbag 704, and finally the straw 304 stops rotating, avoiding the straw 304 from failing to play a good pulling effect on the wrinkled skin after rotating.

[0052] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
