Description

Technical Field

[0002] In recent years, focused ultrasound therapy technology has been increasingly studied and applied, especially in the field of tumor treatment, and new progress has been made. At present, the mainstream focused ultrasound technology in the world is mainly high-intensity focused ultrasound (HIFU). Traditional HIFU, also known as thermal effect HIFU, uses its high-energy ultrasound focusing to rapidly heat the area near the focus to above 65°C to inactivate cells in the lesion site and achieve the purpose of treatment. With the in-depth study of traditional HIFU, the problems caused by traditional HIFU have gradually received attention, especially the heat diffusion problem caused by thermal treatment, which can easily cause complications such as large-area necrosis of surrounding normal tissues and skin burns. Therefore, to ensure the safety and reliability of focused ultrasound therapy technology, the working state of the ultrasonic transducer must be kept stable and reliable, that is, while generating stable sound intensity in the tissue, it can ensure that the temperature of the tissue around the sound intensity focus does not exceed the safe value.

[0003] Ultrasound dose is a key factor in determining the effect of ultrasound treatment, and sound intensity is one of the important parameters that indicate ultrasound dose.

[0004] In order to solve the above problems, it is urgently necessary to provide a device that has both sound intensity measurement function and temperature measurement function to accurately measure ultrasound dose and temperature to ensure the effectiveness and safety of focused ultrasound therapy.

[0052] Ultrasound dose is a key factor in determining the effect of ultrasound treatment, and sound intensity is one of the important parameters that indicate ultrasound dose. In order to achieve safe and effective treatment, it is necessary to measure both the sound intensity and the temperature of the tissue around the focus of the sound intensity. At present, the measurement of sound intensity and temperature is carried out in steps, that is, different devices are used to measure the sound intensity and temperature under the same ultrasound dose. This measurement method requires the use of different simulated tissues, which has large errors.

[0053] In view of the above problems, the utility model provides an ultrasonic therapy dose and temperature measurement device and a treatment equipment, which are used to solve the problem that the existing devices are difficult to take into account both ultrasonic dose measurement and temperature measurement, resulting in large measurement errors, affecting the effectiveness and safety of ultrasonic therapy.

[0054] In the first aspect, the present invention provides an ultrasonic treatment dose and temperature measurement device, see Figure 1 , including: a sound intensity measurement component 2, a temperature measurement component 3, and a bearing rod 1;

[0055] The bearing rod 1 has a first end face and a second end face opposite to each other. The measuring part of the sound intensity measuring component 2 is arranged on the first end face of the bearing rod 1 . The measuring part of the temperature measuring component 3 is arranged on the bearing rod 1 and close to the sound intensity measuring component 2 .

[0056] Compared with the prior art, the utility model has both a sound intensity measurement component and a temperature measurement component, and both the temperature measurement component and the sound intensity measurement component have a measuring part, which can realize the simultaneous measurement of sound intensity and temperature.

[0057] See also Figure 2 As a possible implementation, the sound intensity measurement component 2 includes a piezoelectric ceramic sheet 20, a sound intensity signal line 21 and a ground line 22; the temperature measurement component 3 includes a temperature sensing housing 30, a temperature sensor 31, a first temperature signal line 32 and a second temperature signal line 33;

[0058] The temperature sensing housing 30 is coaxially fastened to the first end surface, and the piezoelectric ceramic piece 20 is coaxially fastened to the end surface of the temperature sensing housing 30 away from the bearing rod 1; one end of the sound intensity signal line 21 is connected to the piezoelectric ceramic piece 20, and the other end is led out; one end of the ground wire 22 is fixed on the inner wall of the bearing rod 1, and the other end is led out;

[0059] The temperature sensor 31 is placed inside the temperature sensing housing 30 and is connected to a first temperature signal line 32 and a second temperature signal line 33 ; the temperature sensor 31 is used to convert a temperature signal into an electrical signal.

[0060] See also Figure 2 , the piezoelectric ceramic piece 20 is coaxially fastened to the end face of the temperature sensing housing 30 away from the bearing rod 1, and the connection method is not limited; one end of the sound intensity signal line 21 is connected to the piezoelectric ceramic piece 20, and the connection method is welding. When in use, the sound pressure signal will act on the piezoelectric ceramic piece 20, so that the piezoelectric ceramic piece 20 generates electric charges. Sound pressure signals of different energies will cause the piezoelectric ceramic piece 20 to have different degrees of deformation and generate different amounts of electric charges, thereby obtaining corresponding electrical signals, which are transmitted to the oscilloscope through the sound intensity signal line 21 for data display. The sound intensity signal line 21 is an anti-interference shielded line or a signal line with anti-interference effect.

[0061] The temperature sensing housing 30 is made of heat-conducting material, which can accurately reflect the external temperature and transmit the temperature signal to the temperature sensor 31. The bearing rod 1 and the temperature sensing housing 30 are both hollow structures, and the temperature sensing housing 30 is coaxially fastened to the first end face of the bearing rod 1. The connection method can be any one of the existing technologies, such as welding, threaded connection or plug-in. After the two are connected, the cavity is still a hollow structure, and the sound intensity signal line 21, the ground line 22, the first temperature signal line 32 and the second temperature signal line 33 all pass through the hollow cavity.

[0062] As a possible implementation, the temperature sensor has a first thermode and a second thermode made of different materials, the first thermode is connected to a first temperature signal line, and the second thermode is connected to a second temperature signal line; the first thermode and the second thermode are joined to form a loop, and the other ends of the first temperature signal line and the second temperature signal line are externally connected to a data processing module;

[0063] A temperature sensor, such as a thermocouple, has two thermocouples; the first thermocouple and the second thermocouple are made of two different conductors, and the first thermocouple and the second thermocouple are joined by welding. Since the free electron density of different conductors is different, there is electron diffusion at the solder joint, thereby generating a contact electromotive force, which is not only related to the material but also to the temperature. The temperature at the solder joint is different, and the degree of electron diffusion is also different, so the output "thermal electromotive force" will be different. Since the output signal is a tiny DC electromotive force within tens of millivolts, the temperature signal line needs to be connected to the data processing module for protection and amplification to ensure that the oscilloscope can collect the electrical signal.

[0064] As a possible implementation manner, outer walls of the first temperature signal line and the second temperature signal line are respectively wrapped with an insulating shielding sheath, or wrapped with a metal sheath and the metal sheath is filled with insulating powder.

[0065] In order to reduce interference and ensure stable signal transmission, the outer walls of the first temperature signal line and the second temperature signal line are respectively wrapped with insulating shielding sheaths, or wrapped with metal sheaths and the metal sheaths are filled with insulating powder. It should be explained that the welding points should not be wrapped in. The insulating shielding sheath can be any one of the existing technologies, and no specific limitation is made here. If a metal sheath is used, it is necessary to fill the metal sheath with insulating powder, such as magnesium oxide.

[0066] See also Figure 3 to Figure 4 As a possible implementation, the sound intensity measurement component 2 includes a bearing shell 23, a piezoelectric ceramic sheet 20, a sound intensity signal line 21 and a ground line 22; the bearing shell 23 and the piezoelectric ceramic sheet 20 constitute a measuring part of the sound intensity measurement component;

[0067] The bearing shell 23 is coaxially fastened to the first end face of the bearing rod 1, and the piezoelectric ceramic piece 20 is coaxially fastened to the end face of the bearing shell 23 away from the bearing rod 1; one end of the sound intensity signal line 21 is connected to the piezoelectric ceramic piece 20, and the other end is led out; one end of the ground wire 22 is fixed on the inner wall of the bearing rod 1, and the other end is led out.

[0068] The bearing shell 23 is coaxially fastened to the first end face of the bearing rod 1, and the connection method can be any one of the existing technologies, such as welding, threaded connection or plug-in; the piezoelectric ceramic piece 20 is coaxially fastened to the end face of the bearing shell 23 away from the bearing rod 1, and the connection method is not limited; one end of the sound intensity signal line 21 is connected to the piezoelectric ceramic piece 20, and the connection method is welding; one end of the ground wire 22 is fixed on the inner wall of the bearing rod 1, and can also be fixed on the inner wall of the bearing shell 23.

[0078] See also Figure 6The first connection point 340 and the second connection point 350 are both movable connection points, for example, a ball head shaft. The movable rod 38 takes the first connection point 340 as the axis and can rotate on the plane formed by the central axis of the movable rod and the central axis of the load-bearing rod; the support rod 37 takes the second connection point 350 as the axis and can rotate on the plane formed by the central axis of the movable rod and the central axis of the load-bearing rod.

[0079] Each movable rod 38 is movably connected to one end of a support rod 37 away from the second connection point at a position close to the middle thereof;

[0080] See also Figure 6 One end of the support rod 37 is connected to the second connection point 350, and the other end is movably connected to the movable rod 38 near the middle position. Considering the convenience of use, any connection point near the middle position of the movable rod can be selected. The function of the support rod 37 is to make the movable rod 38 open to the desired position, as long as the above purpose is achieved.

[0081] See also Figure 3 As a possible implementation method, the length of the movable rod 38 is greater than the height of the load-bearing shell 23 and less than the sum of the heights of the load-bearing rod 1 and the load-bearing shell 23; and the movable rod 38 has an angle α with the direction of the line connecting the second connection point and the first connection point, 0°≤α<45°; the movable rod can sense the external temperature and transmit the temperature signal to the temperature sensor.

[0082] N temperature sensors are distributed in the N movable rods 38 , and each temperature sensor is connected to a first temperature signal line and a second temperature signal line; the temperature sensor is used to convert the temperature signal into an electrical signal.

[0083] The movable rod is made of heat-conducting material, which can accurately reflect the external temperature and transmit the temperature signal to the temperature sensor.

[0085] As an example of a temperature sensor, for example, a thermocouple, the first thermode and the second thermode are composed of two different conductors, and the first thermode and the second thermode are joined by welding. Since the free electron density of different conductors is different, there is electron diffusion at the solder joint, thereby generating a contact electromotive force, which is not only related to the material, but also to the temperature. The temperature at the solder joint is different, and the degree of electron diffusion is also different, so the output "thermal electromotive force" will be different. Since the output signal is a tiny DC electromotive force within tens of millivolts, the temperature signal line needs to be connected to the data processing module for protection and amplification to ensure that the oscilloscope can collect the electrical signal.

[0086] As a possible implementation manner, outer walls of the first temperature signal line and the second temperature signal line are respectively wrapped with an insulating shielding sheath, or wrapped with a metal sheath and the metal sheath is filled with insulating powder.

[0087] In order to reduce interference and ensure stable signal transmission, the outer walls of the first temperature signal line and the second temperature signal line are respectively wrapped with insulating shielding sheaths, or wrapped with metal sheaths and the metal sheaths are filled with insulating powder. It should be explained that the welding points should not be wrapped in. The insulating shielding sheath can be any one of the existing technologies, and no specific limitation is made here.
