Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly relates to an ultrasonic interventional probe with a multi-frequency adjustment function. Background Art

[0002] Since the depths, structures, and characteristics of various organs and tissues in the human body are different, different frequencies and types of probes are usually required to meet specific examination needs. For superficial organs such as the thyroid and breast, probes with higher frequencies and better resolutions are usually used for examination. For deep organs such as the liver and heart, probes with lower frequencies and larger exploration depths are usually used for examination.

[0003] During the detection process, to prevent the risk of cross-infection, doctors usually need to disinfect and wear gloves. When replacing the ultrasonic probe and during the operation process, when the doctor needs to adjust the height or angle of the ultrasonic screen to facilitate observing the ultrasonic image, the doctor usually needs to take off the gloves for operation, which brings inconvenience in use. Therefore, the present invention provides a diagnostic device for the ultrasonic department that is convenient for replacing the ultrasonic probe. Summary of the Invention

[0004] To solve the above problems, the present invention provides an ultrasonic interventional probe with a multi-frequency adjustment function, which facilitates doctors to flexibly switch the ultrasonic probe while ensuring the detection accuracy of the ultrasonic probe.

[0005] To achieve the above object, the technical solution of the present invention is as follows: An ultrasonic interventional probe with a multi-frequency adjustment function includes an ultrasonic probe body for diagnosis and a display screen for displaying ultrasonic images.

[0006] A rotation cavity is opened inside the housing, and a rotation mechanism for switching different ultrasonic probes is provided at the center of the rotation cavity;

[0007] A rotating ring mechanism for controlling the rotation of the robotic arm mechanism is rotationally engaged with the outer wall of the housing.

[0008] Furthermore, a protective film is fixedly connected to the bottom of the housing.

[0009] Furthermore, the rotation mechanism includes a central shaft and an absorption layer. The absorption layer is located inside the housing and is fixedly connected to the housing. The rotation cavity is opened inside the absorption layer;

[0010] One end of the central shaft penetrates through the housing and the absorption layer, and the other end of the central shaft is coaxially connected to a motor. The motor is fixedly connected to the housing; the end of the central shaft penetrating through the housing is connected to a control button for controlling the rotation of the motor;

[0011] A number of telescopic electric push rods are also fixedly connected to the central axis. The electric push rods are located in the rotating cavity and are symmetrically arranged around the central axis. One end of the electric push rod far from the central axis is fixedly connected with a piezoelectric wafer, and the absorption layer is also located between the electric push rod and the piezoelectric wafer. When the electric push rod moves to the farthest end, the piezoelectric wafer abuts against the protective film.

[0012] An airbag is also provided in the rotating cavity. The airbag is located between the piezoelectric wafer and the central axis. One end of the airbag is fixedly connected to the central axis, and the other end of the airbag is fixedly connected to the absorption layer on the piezoelectric wafer.

[0013] The airbag is also connected to a first air pipe. The first air pipe is located inside the cable, and one end of the first air pipe far from the airbag is connected to a vacuum pump. A second air pipe is connected to the first air pipe, and the other end of the second air pipe far from the first air pipe is connected to the rotating cavity.

[0014] It also includes a processor. One end of the cable far from the housing is electrically connected to the processor. The first air pipe is connected to a first electromagnetic valve, the second air pipe is connected to a second electromagnetic valve, and the piezoelectric wafer, the motor, the control button, the electric push rod, the vacuum pump, the first electromagnetic valve and the second electromagnetic valve are electrically connected to the processor.

[0015] The processor is used to input the timing control instructions of the electric push rod, the vacuum pump, the first electromagnetic valve and the second electromagnetic valve, and send corresponding timing control instructions to control the electric push rod, the vacuum pump, the first electromagnetic valve and the second electromagnetic valve based on the start situation of the control button.

[0016] Further, a slip ring is also rotatably fitted on the central axis. The slip ring is fixedly connected to the absorption layer and is electrically connected to the motor, the electric push rod and the piezoelectric wafer. There is an electric wire on the slip ring, and the electric wire is located inside the cable.

[0017] Further, the rotating ring mechanism includes a rotating ring and a clamping ring. The clamping ring is located at the center of the rotating ring. An opening is provided on one side of the clamping ring, and the clamping ring is clamped to one end of the housing close to the cable.

[0018] A sliding groove is opened in the clamping ring, and a slider is slidably fitted in the sliding groove. One end of the slider far from the clamping ring is fixedly connected with a number of connecting rods, and the other end of the connecting rod far from the slider is fixedly connected with the rotating ring.

[0019] A number of pressure sensors are also evenly arranged in the sliding groove. The pressure sensors are used to detect the pressure data applied by the slider to the pressure sensors in real time and send the pressure data to the processor. The processor is used to control the rotation of the robotic arm mechanism based on the pressure data before and after the current time.

[0020] Further, the processor is also used to record and store the real-time position of the pressure sensor, compare the pressure data of each pressure sensor with a set standard value. If the pressure data is greater than the standard value, a reference mark is added to the corresponding pressure sensor; if the pressure data is less than the standard value, a blank mark is added to the corresponding pressure sensor;

[0021] Based on the real-time position corresponding to the pressure sensor before the current time as the base position, the comparison real-time position of the pressure sensor with a reference mark at the current time is obtained, the gap value between the comparison real-time position and the base position is calculated, and a corresponding rotation angle instruction is sent to the robotic arm mechanism based on the gap value.

[0022] Further, a control rod is rotatably fitted on the slider, and a torsion spring is clamped between the control rod and the slider. One end of the torsion spring is fixedly connected to the control rod, and the other end of the torsion spring is fixedly connected to the slider; a magnet block is fixedly connected to the center of the control rod, and a magnetic induction coil is sleeved outside the control rod.

[0024] The pressure sensors are also respectively located on the upper and lower sides of the slider. The processor is used to establish a pressure sensor group based on the distribution position of the pressure sensors in the chute, add corresponding upper and lower marks to the pressure sensor group, obtain the pressure sensor group with a reference mark at the current time, and compare the corresponding pressure data in the pressure sensor group. If the pressure data with an upper mark is greater than or equal to the pressure data with an upper mark, a reduction mark is added to the power value; if the pressure data with an upper mark is less than the pressure data with an upper mark, an increase mark is added to the power value.

[0025] Further, a groove is opened at the center of the snap ring, and a protrusion is fixedly connected to one side of the outer shell close to the cable. The shape of the protrusion is the same as that of the groove.

[0026] Further, a shielding ring is also fixedly connected to the outer wall of the outer shell, and the shielding ring is located outside the central axis.

[0030] 2. In this solution, when the doctor operates the ultrasound probe body for testing, the integrated rotating ring mechanism is used to adjust the rotation direction of the display screen, which is convenient for the doctor to watch the ultrasound image; it also reduces the need for the doctor to change hands to adjust the rotation of the display screen, making it easier for the doctor to perform clinical operations.

[0031] 3. Compared with the existing technology, this solution allows doctors to replace the ultrasound probe without replacing it according to the different detection positions on the human body. It is easy to operate, meets the needs of clinical use, and ensures the subsequent detection accuracy of the ultrasound probe.

[0043] The following will be further described in detail through specific implementation manners:

[0044] Embodiment 1:

[0045] As shown in the attached Figures 1 to 6 figures: An ultrasonic interventional probe with multi-frequency adjustment function includes an ultrasonic probe body for diagnosis and a display screen for displaying ultrasonic images. The display screen is connected with a robotic arm mechanism for supporting the rotation of the display screen. The robotic arm mechanism is an existing mechanism and is not shown in the figure. It mainly includes a robotic arm for supporting the display screen, and a turntable mechanism fixedly connected to the bottom of the robotic arm for driving the rotation of the robotic arm.

[0046] The ultrasonic probe body includes a housing 1 and an ultrasonic probe for generating different ultrasonic frequencies. A cable 11 is fixedly connected to the top of the housing 1, and the cable 11 is electrically connected to the ultrasonic probe. A protective film 12 is fixedly connected to the bottom of the housing 1.

[0047] A rotating cavity 13 is formed inside the outer shell 1, and a rotating mechanism for switching different ultrasonic probes is provided at the center of the rotating cavity 13; the rotating mechanism includes a central shaft 2 and an absorption layer 6. The absorption layer 6 is located inside the outer shell 1 and is fixedly connected to the outer shell 1. The rotating cavity 13 is formed inside the absorption layer 6; one end of the central shaft 2 penetrates through the outer shell 1 and the absorption layer 6, and a shielding ring is also welded on the outer wall of the outer shell 1. The shielding ring is located outside the central shaft 2; the other end of the central shaft 2 is coaxially connected to a motor 20. In this embodiment, the motor 20 rotates forward and reversely according to a preset program, so that the piezoelectric wafer 7 rotates back and forth at a certain angle. The motor 20 is fixedly connected to the outer shell 1 by bolts; one end of the central shaft 2 penetrating through the outer shell 1 is connected with a control button 21, and the control button 21 is used to control the rotation of the motor 20. A plurality of telescopic electric push rods 5 are also arranged on the central shaft 2 by screws. The electric push rods 5 are located inside the rotating cavity 13 and are symmetrically arranged with the central shaft 2 as the center; one end of the electric push rod 5 far from the central shaft 2 is fixedly connected to a piezoelectric wafer 7, and the absorption layer 6 is located between the electric push rod 5 and the piezoelectric wafer 7; when the elongation of the electric push rod 5 is the largest, the piezoelectric wafer 7 abuts against the protective film 12; an airbag 8 is also arranged inside the rotating cavity 13. The airbag 8 is located between the piezoelectric wafer 7 and the central shaft 2. One end of the airbag 8 is adhesively connected to the central shaft 2, and the other end of the airbag 8 is adhesively connected to the absorption layer 6 on the piezoelectric wafer 7. And a slip ring 22 is also rotatably fitted on the central shaft 2. The slip ring 22 is fixedly connected to the absorption layer 6. The slip ring 22 is electrically connected to the motor 20, the electric push rod 5 and the piezoelectric wafer 7. There is an electric wire 23 on the slip ring 22, and the electric wire 23 is located inside the cable 11.

[0048] The airbag 8 is also communicated with a first air pipe 81. In this embodiment, the first air pipe 81 is a deformable pipe with a variable length to adapt to the rotational change of the airbag 8; the first air pipe 81 is located inside the cable 11, and one end of the first air pipe 81 far from the airbag 8 is communicated with a vacuum pump (not shown in the figure); a second air pipe 82 is communicated with the first air pipe 81, and one end of the second air pipe 82 far from the first air pipe 81 is communicated with the rotating cavity 13.

[0049] It also includes a processor. One end of the cable 11 far from the outer shell 1 is electrically connected to the processor. The first air pipe 81 is communicated with a first electromagnetic valve 83, and the second air pipe 82 is communicated with a second electromagnetic valve 84. The piezoelectric wafer 7, the motor 20, the control button 21, the electric push rod 5, the vacuum pump, the first electromagnetic valve 83 and the second electromagnetic valve 84 are electrically connected to the processor; the processor is used to input the timing control instructions of the electric push rod 5, the vacuum pump, the first electromagnetic valve 83 and the second electromagnetic valve 84, and send corresponding timing control instructions to control the electric push rod 5, the vacuum pump, the first electromagnetic valve 83 and the second electromagnetic valve 84 based on the start situation of the control button 21. In this embodiment, the ultrasonic imaging principle of the piezoelectric wafer 7 is prior art and will not be described in detail in this embodiment.

[0050] A swivel mechanism for controlling the rotation of the robotic arm mechanism is rotatably fitted to the outer wall of the housing 1. The swivel mechanism includes a rotating ring 4 and a clamping ring 3. The clamping ring 3 is located at the center of the rotating ring 4. An opening is provided on one side of the clamping ring 3. The clamping ring 3 is clamped to one end of the housing 1 close to the cable 11. A chute 32 is formed in the clamping ring 3. A slider 31 is slidably fitted in the chute 32. One end of the slider 31 away from the clamping ring 3 is fixedly connected with a plurality of connecting rods 41. One end of the connecting rods 41 away from the slider 31 is fixedly connected with the rotating ring 4. A plurality of pressure sensors (not shown in the figure) are also evenly arranged in the chute 32. The pressure sensors are used to detect the pressure data applied by the slider 31 to the pressure sensors in real time and send the pressure data to the processor. The processor is used to control the rotation of the robotic arm mechanism based on the pressure data before and after the current time. A groove is formed at the center of the clamping ring 3. A protrusion is integrally formed on one side of the housing 1 close to the cable 11. The shapes of the protrusion and the groove match each other.

[0051] The specific implementation process is as follows:

[0052] During use, the physician installs the clamping ring 3 on the housing 1 according to needs, so that the swivel mechanism is installed on the housing 1. During the installation of the clamping ring 3, through the settings of the groove and the protrusion, the stability during the clamping of the clamping ring 3 to the housing 1 is improved, so as to reduce the occurrence of the movement of the clamping ring 3 during the clamping process. During the ultrasonic detection operation of the housing 1, through the shielding of the shielding ring, the contact between the physician and the central axis 2 during rotation is reduced, and the possible frictional damage to the physician is reduced. Then, through the isolation of the protective film 12 during the contact between the ultrasonic probe and the outside, the wear of the ultrasonic probe is reduced or prevented, thereby prolonging the service life of the ultrasonic probe. Through the setting of the electric slip ring 22, it is adapted to the telecommunication connection of the piezoelectric wafer 7 and the electric push rod 5 connected to the rotating central axis 2, so as to ensure the continuous power supply requirements for the piezoelectric wafer 7 and the electric push rod 5.

[0053] During the use of the ultrasonic probe body, the physician can replace the ultrasonic probe by pressing the control button 21 according to the different detection positions of the human body. By the starting condition of the control button 21, the output shaft of the motor 20 is controlled to drive the central axis 2 to rotate, and at the same time, a preset timing control instruction is started to control the contraction and elongation of the electric push rod 5, so as to cooperate to realize the rotation switching of the piezoelectric wafers 7 in different directions, so that the replacement process can be carried out without replacing the ultrasonic probe, which has the characteristics of convenient operation and meets the clinical use requirements.

[0054] During the rotation of the piezoelectric wafer 7, the electric push rod 5 drives the corresponding piezoelectric wafer 7 to retract, and the airbag 8 contracts towards the center. When the central shaft 2 drives the piezoelectric wafer 7 to rotate at an angle of 45 degrees or 90 degrees (the angular rotation change is determined based on the number of piezoelectric wafers 7 provided inside the rotation cavity 13), based on a preset timing control instruction, the corresponding electric push rod 5 is activated to push the piezoelectric wafer 7 into contact with the protective film 12, and the corresponding first solenoid valve 83 is activated to connect the airbag 8 with the first air pipe 81. At this time, the vacuum pump conveys external air into the airbag 8 to assist in pushing the piezoelectric wafer 7 to move towards the side away from the central shaft 2, facilitating the fitting of the piezoelectric wafer 7 with the protective film 12.

[0055] After the electric push rod 5 fully extends, based on the timing control instruction, the first solenoid valve 83 is closed, and the second solenoid valve 84 is opened to connect the second air pipe 82 with the first air pipe 81, enabling the vacuum pump to discharge the remaining air inside the rotation cavity 13. Based on the pressure difference between the rotation cavity 13 and the airbag 8, the gap between the piezoelectric wafer 7 and the protective film 12 is squeezed, facilitating the tight fitting between the piezoelectric wafer 7 and the protective film 12, reducing the leakage or reflection of some ultrasonic energy caused by the formed gap back to the piezoelectric wafer 7. Then, the absorption layer 6 blocks the inertial vibration of the piezoelectric wafer 7 and absorbs the acoustic energy radiated from the back of the wafer, ensuring the performance and image quality of the ultrasonic probe.

[0056] Meanwhile, since a detachable mechanism is formed between the snap ring 3 and the housing 1, it is convenient to perform installation and disassembly processing as needed during use, to meet the usage requirements of different ultrasonic probe bodies. During the use of the ultrasonic probe body, the physician can, without loosening the grip on the ultrasonic probe body, use a finger to flip to drive the rotating ring 4 to drive the slider 31 to move within the sliding groove 32, controlling the rotating direction of the slider 31 towards both sides, and adjusting the rotating direction of the current display screen towards both sides, facilitating the physician to adjust the display screen during the actual detection process without performing additional disinfection work or removing the ultrasonic probe body, and facilitating the physician to observe and operate during ultrasonic detection in different orientations.

[0057] Embodiment 2:

[0058] The difference from Embodiment 1 is that the processor is further configured to input and store the real-time position of the pressure sensor, compare the pressure data of each pressure sensor with a set standard value. If the pressure data is greater than the standard value, a reference mark is added to the corresponding pressure sensor; if the pressure data is less than the standard value, a blank mark is added to the corresponding pressure sensor. Then, based on the real-time position corresponding to the pressure sensor before the current time as the base position, the comparison real-time position of the pressure sensor with a reference mark at the current time is obtained, the gap value between the comparison real-time position and the base position is calculated, and a corresponding rotation angle instruction is sent to the robotic arm mechanism based on the gap value.

[0059] For example, by comparing the pressure data fed back by the pressure sensor to generate a corresponding rotation angle adjustment, it is convenient for the doctor to adjust and control the rotation direction of the display screen during the operation.

[0060] Embodiment 3:

[0061] Combined as Figure 5 As shown, the difference from Embodiment 2 is that a control rod 42 is rotatably fitted on the slider 31, a torsion spring is clamped between the control rod 42 and the slider 31, one end of the torsion spring is fixedly connected to the control rod 42, and the other end of the torsion spring is fixedly connected to the slider 31. A magnet block is fixedly connected to the center of the control rod 42, a magnetic induction coil is sleeved outside the control rod 42, the magnetic induction coil is rotatably fitted with the slider 31, and the magnetic induction coil is electrically connected to the processor. The magnetic induction coil is configured to generate a corresponding magnetic induction current based on the rotation of the control rod 42, send the magnetic induction current to the processor, and the processor is configured to input and store the power value of the piezoelectric wafer 7 corresponding to the magnetic induction current, and then output the corresponding power value based on the magnetic induction current.

[0062] Pressure sensors are also respectively located on the upper and lower sides of the slider 31. The processor is configured to establish a pressure sensor group based on the distribution position of the pressure sensors in the chute 32, add corresponding upper and lower marks to the pressure sensor group, obtain the pressure sensor group with a reference mark at the current time, compare the corresponding pressure data in the pressure sensor group. If the pressure data with an upper mark is greater than or equal to the pressure data with an upper mark, a reduction mark is added to the power value; if the pressure data with an upper mark is less than the pressure data with an upper mark, an increase mark is added to the power value.

[0063] For example, through the up and down rotation change of the control rod 42, to drive a corresponding change in the induced current generated by the control rod 42 in the magnetic induction coil, to generate a corresponding change in the power value adjustment, and then to determine whether it is an increase or decrease change at the current time through the comparison of the pressure data of the pressure sensors on the upper and lower sides, so as to facilitate the doctor to adjust the power of the ultrasonic probe, which has the advantage of flexible operation.

[0064] Embodiment 4:

[0065] The difference from Embodiment 3 is that a number of indicating lights 14 for displaying the switching of different piezoelectric wafers 7 are snap-connected to the outer wall of the housing 1, and the indicating lights 14 are used to sequentially and cyclically display based on the activation of the control button 21.

[0066] The specific implementation process is as follows: The type of the current piezoelectric wafer 7 can be more intuitively determined through the indicating lights 14, so as to facilitate the physician to understand the ultrasonic probe corresponding to the frequency at the current time and facilitate the physician to perform operation and treatment.

[0067] Obviously, the above embodiments are only examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
