Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to an ultrasonic examination probe. Background Art

[0002] Ultrasonic probes in the medical field are mainly used for ultrasonic diagnosis, such as B-ultrasound, ultrasonic physiotherapy, ultrasonic therapeutic instruments, etc. For current ultrasonic probes, when a patient goes to the hospital for ultrasonic detection, medical staff need to apply the coupling agent in the bottled coupling agent to the detection site of the patient, and then use their hands or directly use the probe to evenly apply the coupling agent on the patient's skin. However, during the inspection process, a large amount of coupling agent needs to be applied to the patient's skin to ensure the effect of ultrasonic detection, and the coupling agent is not recycled, which causes great waste. Summary of the Invention

[0003] The present invention aims to provide an ultrasonic examination probe to solve the problem that a large amount of coupling agent needs to be applied during the use of existing ultrasonic probes.

[0004] To solve the above technical problems, the present invention provides the following technical solution: An ultrasonic examination probe includes an inner cylinder, an outer cylinder, and a control system. The inner cylinder is sleeved inside the outer cylinder. One end of the inner cylinder is provided with a probe body for detection. A fixing ring is arranged inside the inner cylinder. A heavy ball is arranged at the center of the fixing ring. Three connecting springs connected to the heavy ball are arranged inside the fixing ring. A pressure sensor is arranged at the connection between the connecting spring and the fixing ring. A substrate in the shape of an annular belt is arranged between the inner cylinder and the outer cylinder, on the same side as the probe body. Three arc-shaped electromagnets are arranged on the top of the substrate. The three electromagnets are connected end to end to form a complete circle. A vertical through groove is arranged on the substrate. Three movable plates are slidably connected inside the through groove. The three movable plates are connected end to end to form a complete circle. Magnetic conduction plates perpendicular to the movable plates are arranged on both sides of the movable plate. Compression springs are arranged between the magnetic conduction plate and the electromagnet. The control system includes a processor, a power supply, and a circuit breaker. The power supply, the processor, the circuit breaker, the pressure sensor, and the electromagnet form a circuit.

[0005] Working principle of the present invention: When using this solution to examine a patient, apply the coupling agent on the patient's skin and move the probe body back and forth to obtain a clear image. During the movement, since there is a fixed ring inside the inner cylinder, a heavy ball is provided at the center of the fixed ring, and three connecting springs connected to the heavy ball are provided inside the fixed ring. A pressure sensor is provided at the connection between the connecting spring and the fixed ring. In this way, no matter which direction the probe body moves, two springs will be subjected to tensile force. The corresponding pressure sensor senses this pressure and converts it into an electrical signal and sends it to the processor. After being processed by the processor, a closing signal is output, causing the circuit breaker to close and connect the circuit. As a result, two arc-shaped electromagnets corresponding to the pressure sensors on the substrate are energized. After the electromagnets are energized, they generate magnetic force, which will generate a suction force on the magnetic conductive plate. Also, since magnetic conductive plates perpendicular to the movable plate are provided on both sides of the movable plate, and the through groove is slidably connected to the movable plate, this suction force will cause the compression spring to be compressed, and the movable plate slides downward in the through groove, and then contacts the skin, and plays a role of scraping the coupling agent as the probe body moves. In this way, the coupling agent will be pushed back and forth along with the probe body until after the examination is completed, the probe body stops moving, the pressure sensor is not subjected to tensile force, does not send an electrical signal to the processor, the processor always outputs a disconnection signal, causing the circuit breaker to disconnect, the electromagnet is not conductive, the magnetic conductive plate is not subjected to suction force, and the compression spring has an upward thrust on the movable plate to restore deformation, causing the movable plate to move upward, and the movable plate no longer has the function of scraping the coupling agent.

[0006] The beneficial effects of the present invention are as follows: In this solution, the pressure sensor senses the tensile force and controls the movable plate to extend in the through groove, thereby playing a role of scraping the coupling agent in the moving direction of the probe body. In this way, it is not necessary to smear the coupling agent all over the patient's skin, but only need to apply the coupling agent in one place to complete the examination of an area, saving the usage amount of the coupling agent.

[0007] The following is the optimization of the basic technical solution:

[0008] Further, the lower end of the movable plate is covered with a soft pad. In this way, when contacting the human skin, the human body feels more comfortable, and the airtightness between the movable plate and the human body is also ensured.

[0009] Further, the lower end of the movable plate is on the same plane as the probe body. In this way, the resistance during the movement of the probe body becomes smaller, and the examination effect is better.

[0010] Further, it further includes a recovery device for sucking the coupling agent. In this way, the coupling agent can be sucked into the recovery device for recycling after the examination. Description of the drawings

[0013] The following is a further detailed description through specific embodiments:

[0014] The reference numerals in the accompanying drawings of the specification include: outer cylinder 1, inner cylinder 2, movable plate 3, magnetic conductive plate 4, compression spring 5, heavy ball 6, connecting spring 7, electromagnet 8, substrate 9, and probe body 10.

[0015] The embodiment is basically as Figure 1 and Figure 2 shown: An ultrasonic inspection probe includes an inner cylinder 2, an outer cylinder 1, a control system, and a recovery device for sucking the coupling agent. The inner cylinder 2 is sleeved inside the outer cylinder 1. A probe body 10 for detection is provided at one end of the inner cylinder 2. A fixing ring is provided inside the inner cylinder 2, and a heavy ball 6 is provided at the center of the fixing ring. Three connecting springs 7 connected to the heavy ball 6 are provided inside the fixing ring, and a pressure sensor is provided at the connection between the connecting spring 7 and the fixing ring. A substrate 9 in the shape of an annular belt is provided between the inner cylinder 2 and the outer cylinder 1. The substrate 9 is on the same side as the probe body 10. Three arc-shaped electromagnets 8 are provided at the top of the substrate 9. The three electromagnets 8 are connected end to end to form a complete circle. A through groove in the vertical direction is provided on the substrate 9, and three movable plates 3 are slidably connected in the through groove. The three movable plates 3 are connected end to end to form a complete circle. A soft pad is covered at the lower end of the movable plate 3. The lower end of the movable plate 3 is on the same plane as the probe body 10. Magnetic conductive plates 4 perpendicular to the movable plate 3 are provided on both sides of the movable plate 3. A compression spring 5 is provided between the magnetic conductive plate 4 and the electromagnet 8. The control system includes a processor, a power supply, and a circuit breaker. The power supply, the processor, the circuit breaker, the pressure sensor, and the electromagnet 8 form a circuit.

[0016] When using this solution to examine a patient, apply the coupling agent on the patient's skin and move the probe body 10 back and forth to obtain a clear image. During the movement, since there is a fixed ring inside the inner cylinder 2, a heavy ball 6 is provided at the center of the fixed ring, and three connecting springs 7 connected to the heavy ball 6 are provided inside the fixed ring. A pressure sensor is provided at the connection between the connecting spring 7 and the fixed ring. In this way, no matter which direction the probe body 10 moves, two springs will be subjected to tensile force, and the corresponding pressure sensor senses this pressure and converts it into an electrical signal and sends it to the processor. After being processed by the processor, a closing signal is output, causing the circuit breaker to close and connect the circuit. Furthermore, two arc-shaped electromagnets 8 corresponding to the pressure sensor on the substrate 9 are energized. After the electromagnets 8 are energized, they generate magnetic force, which will generate a suction force on the magnetic conduction plate 4. Also, since magnetic conduction plates 4 perpendicular to the movable plate 3 are provided on both sides of the movable plate 3, and the through groove is slidably connected to the movable plate 3, this suction force will cause the compression spring 5 to be compressed, and the movable plate 3 slides downward in the through groove and then contacts the skin, and plays a role of scraping the coupling agent as the probe body 10 moves. In this way, the coupling agent will be pushed back and forth with the probe body 10 until after the examination is completed, the probe body 10 no longer moves, the pressure sensor will not be subjected to tensile force, and no electrical signal will be sent to the processor. The processor always outputs a disconnection signal, causing the circuit breaker to disconnect, the electromagnets 8 to be non-conductive, the magnetic conduction plate 4 not to be subjected to suction force, and the compression spring 5 to have an upward thrust on the movable plate 3 to make the movable plate 3 move upward, and the movable plate 3 no longer has the function of scraping the coupling agent.
