Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an ultrasound interventional probe with multi-frequency adjustment function. Background Technology

[0002] Because the depth, structure, and characteristics of different organs and tissues in the human body vary, different frequencies and types of probes are usually required to meet specific examination needs. For example, superficial organs such as the thyroid gland and breast are usually examined using probes with higher frequencies and better resolution, while deep organs such as the liver and heart are usually examined using probes with lower frequencies and greater depth of penetration.

[0003] During testing, physicians typically need to disinfect and wear gloves to prevent cross-infection. However, when changing ultrasound probes or adjusting the height or angle of the ultrasound screen for better image viewing, physicians usually need to remove their gloves, causing inconvenience. Therefore, this invention provides an ultrasound diagnostic device that facilitates probe replacement. Summary of the Invention

[0004] To address the aforementioned issues, this invention provides an ultrasound interventional probe with multi-frequency adjustment capabilities, facilitating flexible switching of ultrasound probes by physicians while ensuring the detection accuracy of the ultrasound probes.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows: an ultrasound interventional probe with multi-frequency adjustment function includes an ultrasound probe body for diagnosis and a display screen for displaying ultrasound images. The display screen is connected to a robotic arm mechanism for supporting the rotation of the display screen. The ultrasound probe body includes a housing and an ultrasound probe for generating different ultrasound frequencies. A cable is fixedly connected to the top of the housing, and the cable is electrically connected to the ultrasound probe.

[0006] The outer shell has a rotating cavity, and a rotating mechanism for switching different ultrasonic probes is located at the center of the rotating cavity;

[0007] The outer wall of the outer casing is fitted with a rotating ring mechanism for controlling the rotation of the robotic arm mechanism.

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

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

[0010] One end of the central shaft passes through the outer shell and the absorption layer, and the other end of the central shaft is coaxially connected to a motor, which is fixedly connected to the outer shell; a control button is connected to the end of the central shaft that passes through the outer shell, and the control button is used to control the rotation of the motor.

[0011] Several telescopic electric actuators are also fixedly connected to the central shaft. The electric actuators are located inside the rotating cavity and are arranged symmetrically with the central shaft as the center. A piezoelectric crystal is fixedly connected to the end of the electric actuator away from the central shaft, and the absorption layer is located between the electric actuator and the piezoelectric crystal. When the electric actuator moves to the farthest end, the piezoelectric crystal abuts against the protective film.

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

[0013] The airbag is also connected to a first air tube, which is located inside the cable, and the end of the first air tube away from the airbag is connected to a vacuum pump; a second air tube is connected to the first air tube, and the end of the second air tube away from the first air tube is connected to the rotating cavity.

[0014] It also includes a processor, with one end of the cable away from the casing electrically connected to the processor, a first air pipe connected to a first solenoid valve, a second air pipe connected to a second solenoid valve, a piezoelectric chip, a motor, control buttons, an electric actuator, a vacuum pump, the first solenoid valve, and the second solenoid valve electrically connected to the processor.

[0015] The processor is used to input timing control instructions for the electric actuator, vacuum pump, first solenoid valve and second solenoid valve, and to send corresponding timing control instructions to control the electric actuator, vacuum pump, first solenoid valve and second solenoid valve based on the activation status of the control button.

[0016] Furthermore, an electric slip ring is rotatably fitted on the central shaft. The electric slip ring is fixedly connected to the absorption layer and electrically connected to the motor, electric push rod, and piezoelectric crystal. There are wires on the electric slip ring, and the wires are located inside the cable.

[0017] Furthermore, the rotating mechanism includes a rotating ring and a retaining ring. The retaining ring is located at the center of the rotating ring, and an opening is opened on one side of the retaining ring. The retaining ring is engaged with the end of the housing near the cable.

[0018] The retaining ring has a groove, and a slider is slidably fitted in the groove. Several connecting rods are fixedly connected to the end of the slider away from the retaining ring, and the end of the connecting rod away from the slider is fixedly connected to the rotating ring.

[0019] Several pressure sensors are also evenly arranged inside the chute. The pressure sensors are used to detect the pressure data applied by the slider to the pressure sensor 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] Furthermore, the processor is also used to input and store the real-time position of the pressure sensor, compare the pressure data of each pressure sensor with the set standard value, and add a reference mark to the corresponding pressure sensor if the pressure data is greater than the standard value; if the pressure data is less than the standard value, add a blank mark to the corresponding pressure sensor.

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

[0022] Furthermore, a control rod is rotatably fitted on the slider, and a torsion spring is snapped 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 is fixedly connected to the center of the control rod, and a magnetic induction coil is fitted around the control rod. The magnetic induction coil is rotatably fitted with the slider, and the magnetic induction coil is electrically connected to the processor.

[0023] The magnetic induction coil is used to generate a corresponding magnetic induction current based on the rotation of the control lever. The magnetic induction current is sent to the processor, which is used to input and store the power value of the piezoelectric chip corresponding to the magnetic induction current, and then output the corresponding power value based on the magnetic induction current.

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

[0025] Furthermore, a groove is opened in the center of the retaining ring, and a protrusion is fixedly connected to the side of the outer shell near the cable, with the protrusion having the same shape as the groove.

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

[0027] Furthermore, several indicator lights are fixedly connected to the outer wall of the housing to display the switching of different piezoelectric crystals. The indicator lights are used to display the information in a sequential cycle based on the activation of the control button.

[0028] The above approach has the following beneficial effects:

[0029] 1. This solution uses a rotating mechanism to form a detachable mechanism with the outer shell, which allows physicians to install and disassemble the device according to their actual needs, thereby meeting their operational requirements and improving the device's applicability.

[0030] 2. In this solution, during the ultrasound probe operation, the integrated rotating mechanism adjusts the rotation direction of the display screen, making it easier for the physician to view the ultrasound images. It also reduces the need for the physician to manually switch hands to adjust the rotation of the display screen, thus facilitating clinical operations.

[0031] 3. Compared with existing technologies, this solution allows physicians to replace the ultrasound probe without changing it, depending on the location of the human body being examined. It is easy to operate, meets clinical needs, and ensures the accuracy of subsequent ultrasound probe examinations.

[0032] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0043] The following detailed description illustrates the specific implementation method:

[0044] Example 1:

[0045] As attached Figures 1 to 6 As shown: An ultrasound interventional probe with multi-frequency adjustment function includes an ultrasound probe body for diagnosis and a display screen for displaying ultrasound images. The display screen is connected to 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 for driving the robotic arm to rotate is fixedly connected to the bottom 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] The outer casing 1 has a rotating cavity 13, 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 casing 1 and is fixedly connected to the outer casing 1. The rotating cavity 13 is located inside the absorption layer 6. One end of the central shaft 2 passes through the outer casing 1 and the absorption layer 6, and a shielding ring is welded to the outer wall of the outer casing 1, 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 reverse according to a preset program, causing the piezoelectric crystal 7 to rotate back and forth at a certain angle. The motor 20 is fixedly connected to the outer casing 1 by bolts. A control button 21 is connected to the end of the central shaft 2 that passes through the outer casing 1. The control button 21 is used to control the rotation of the motor 20. Several retractable electric actuators 5 are mounted on the central shaft 2 via screws. These actuators 5 are located within the rotating cavity 13 and are symmetrically arranged around the central shaft 2. A piezoelectric wafer 7 is fixedly connected to the end of each actuator 5 furthest from the central shaft 2, and an absorption layer 6 is located between the actuator 5 and the piezoelectric wafer 7. When the actuator 5 is at its maximum extension, the piezoelectric wafer 7 abuts against the protective film 12. An air bladder 8 is also provided within the rotating cavity 13, located between the piezoelectric wafer 7 and the central shaft 2. One end of the air bladder 8 is bonded to the central shaft 2, and the other end is bonded to the absorption layer 6 on the piezoelectric wafer 7. An electric slip ring 22 is also rotatably fitted on the central shaft 2. The slip ring 22 is fixedly connected to the absorption layer 6 and electrically connected to the motor 20, the electric actuators 5, and the piezoelectric wafer 7. A wire 23 is attached to the slip ring 22 and is located within the cable 11.

[0048] The airbag 8 is also connected to a first air tube 81. In this embodiment, the first air tube 81 is a deformable tube with a variable length to adapt to the rotation of the airbag 8. The first air tube 81 is located inside the cable 11, and the end of the first air tube 81 away from the airbag 8 is connected to a vacuum pump (not shown in the figure). A second air tube 82 is connected to the first air tube 81, and the end of the second air tube 82 away from the first air tube 81 is connected to the rotating cavity 13.

[0049] It also includes a processor. The end of the cable 11 away from the outer casing 1 is electrically connected to the processor. The first air pipe 81 is connected to the first solenoid valve 83, and the second air pipe 82 is connected to the second solenoid valve 84. The piezoelectric crystal 7, motor 20, control button 21, electric actuator 5, vacuum pump, first solenoid valve 83 and second solenoid valve 84 are electrically connected to the processor. The processor is used to input the timing control commands of the electric actuator 5, vacuum pump, first solenoid valve 83 and second solenoid valve 84, and to send corresponding timing control commands to control the electric actuator 5, vacuum pump, first solenoid valve 83 and second solenoid valve 84 based on the activation status of the control button 21. In this embodiment, the ultrasonic imaging principle of the piezoelectric crystal 7 is existing technology, and will not be described in detail in this embodiment.

[0050] The outer wall of the outer casing 1 is rotatably fitted with a rotating ring mechanism for controlling the rotation of the robotic arm mechanism. The rotating ring mechanism includes a rotating ring 4 and a retaining ring 3. The retaining ring 3 is located at the center of the rotating ring 4, and has an opening on one side. The retaining ring 3 engages with the end of the outer casing 1 closest to the cable 11. A sliding groove 32 is formed inside the retaining ring 3, and a slider 31 is slidably fitted within the groove 32. Several connecting rods 41 are fixedly connected to the end of the slider 31 away from the retaining ring 3, and the end of the connecting rods 41 away from the slider 31 is fixedly connected to the rotating ring 4. Several pressure sensors (not shown in the figure) are also evenly arranged inside the groove 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 controls 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 retaining ring 3, and a protrusion is integrally formed on the side of the outer casing 1 closest to the cable 11. The shape of the protrusion matches the groove.

[0051] The specific implementation process is as follows:

[0052] During use, the physician installs the retaining ring 3 onto the housing 1 as needed, thus mounting the rotating mechanism onto the housing 1. During the installation of the retaining ring 3, the grooves and protrusions enhance the stability of the retaining ring 3 during engagement with the housing 1, reducing the likelihood of movement. During ultrasound examination using the housing 1, the shielding ring reduces contact between the physician and the rotating central shaft 2, minimizing potential frictional damage. The protective film 12 further isolates the ultrasound probe from external contact, reducing or preventing wear and extending its lifespan. The slip ring 22 facilitates the electrical connection between the slip ring 22 and the piezoelectric crystal 7 and electric actuator 5 connected to the rotating central shaft 2, ensuring a continuous power supply to these components.

[0053] During the use of the ultrasound probe, the physician can change the ultrasound probe by pressing the control button 21 according to the different positions of the human body being tested. The activation of the control button 21 controls the output shaft of the motor 20 to drive the central shaft 2 to rotate. At the same time, the preset timing control command is activated to control the electric push rod 5 to retract and extend, so as to realize the rotation and switching of the piezoelectric crystal 7 in different positions. This allows for replacement without changing the ultrasound probe, which is convenient to operate and meets the needs of clinical use.

[0054] During the rotation of the piezoelectric crystal 7, the electric push rods 5 drive the corresponding piezoelectric crystal 7 to retract, and the airbag 8 contracts towards the center. When the central shaft 2 drives the piezoelectric crystal 7 to rotate at a 45-degree angle or a 90-degree angle (the angle of rotation is determined based on the number of piezoelectric crystals 7 set inside the rotating cavity 13), the corresponding electric push rods 5 are activated based on the preset timing control command to push the piezoelectric crystal 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 tube 81. At this time, the vacuum pump delivers outside air into the airbag 8 to assist in pushing the piezoelectric crystal 7 to move away from the central shaft 2, so that the piezoelectric crystal 7 can adhere to the protective film 12.

[0055] When the electric actuator 5 is fully extended, the first solenoid valve 83 is closed and the second solenoid valve 84 is opened based on the timing control command to connect the second air pipe 82 with the first air pipe 81. This allows the vacuum pump to expel the residual air inside the rotating cavity 13. Based on the pressure difference between the rotating cavity 13 and the air bladder 8, the gap between the piezoelectric crystal 7 and the protective film 12 is squeezed to achieve a tight fit between the piezoelectric crystal 7 and the protective film 12. This reduces the leakage or reflection of ultrasonic energy back to the piezoelectric crystal 7 caused by the gap. The absorption layer 6 then prevents the inertial vibration of the piezoelectric crystal 7 and absorbs the acoustic energy radiated from the back of the crystal, thus ensuring the performance and image quality of the ultrasonic probe.

[0056] Meanwhile, the detachable mechanism between the retaining ring 3 and the outer shell 1 allows for easy installation and disassembly as needed during use, adaptable to different ultrasound probe body requirements. During use, the physician can rotate the probe body using their fingers without releasing their grip, causing the rotating ring 4 to move the slider 31 within the groove 32. This controls the rotation direction of the slider 31 to both sides, adjusting the current rotation direction of the display screen. This allows the physician to adjust the display screen without additional disinfection or removing the ultrasound probe body during actual testing, facilitating observation and operation from different angles during ultrasound examinations.

[0057] Example 2:

[0058] The difference from Embodiment 1 is that the processor is also used to input and store the real-time position of the pressure sensor, compare the pressure data of each pressure sensor with the set standard value, add a reference mark to the corresponding pressure sensor if the pressure data is greater than the standard value, add a blank mark to the corresponding pressure sensor if the pressure data is less than the standard value, and then use the real-time position of the pressure sensor corresponding to the current time as the base position to obtain the real-time position of the pressure sensor with the reference mark at the current time, calculate the difference value between the real-time position and the base position, and send the corresponding rotation angle command to the robotic arm mechanism based on the difference value.

[0059] For example, by comparing pressure data fed back by pressure sensors, a corresponding rotation angle adjustment can be generated, making it convenient for doctors to adjust and control the rotation direction of the display screen during operation.

[0060] Example 3:

[0061] Combination such as Figure 5 As shown, the difference from Embodiment 2 is that a control rod 42 is rotatably mounted on the slider 31, and a torsion spring is engaged 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 is fixedly connected to the slider 31. A magnet is fixedly connected to the center of the control rod 42, and a magnetic induction coil is sleeved on the control rod 42. The magnetic induction coil is rotatably engaged with the slider 31, and is electrically connected to the processor. The magnetic induction coil is used to generate a corresponding magnetic induction current based on the rotation of the control rod 42, and sends the magnetic induction current to the processor. The processor is used to input and store the power value of the piezoelectric chip 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 located on the upper and lower sides of slider 31. The processor is used to establish a pressure sensor group based on the distribution of pressure sensors in the slide groove 32, add corresponding upper and lower marks to the pressure sensor group, obtain the pressure sensor group with reference marks at the current time, compare the corresponding pressure data in the pressure sensor group, if the pressure data with the upper mark is greater than or equal to the pressure data with the upper mark, then add a decrease mark to the power value; if the pressure data with the upper mark is less than the pressure data with the upper mark, then add an increase mark to the power value.

[0063] For example, by rotating the control lever 42 up and down, the control lever 42 can generate a corresponding change in induced current in the magnetic induction coil, thereby generating a corresponding power value adjustment. Then, by comparing the pressure data of the pressure sensors on the upper and lower sides, the current time is determined to increase or decrease, which facilitates the physician to adjust the power of the ultrasound probe and has the advantage of flexible operation.

[0064] Example 4:

[0065] The difference from Embodiment 3 is that a number of indicator lights 14 for displaying the switching of different piezoelectric crystals 7 are snapped onto the outer wall of the housing 1. The indicator lights 14 are used to display sequentially in a cycle based on the activation of the control button 21.

[0066] The specific implementation process is as follows: Indicator light 14 is used to more intuitively determine the type of piezoelectric chip 7, so that doctors can understand the ultrasound probe corresponding to the current time and frequency, which facilitates the operation and treatment of doctors.

[0067] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
