Description

Technical Field

[0001] This application relates to the field of medical devices, and more particularly to a transducer temperature control method and system, and a readable storage medium. Background Technology

[0002] An ultrasonic bone scalpel is a medical device used to cut or break bone tissue. It converts electrical energy into mechanical energy through a transducer inside the handle, causing the scalpel head to be in a high-frequency resonant mode. The powerful mechanical acceleration of the scalpel head is used to pulverize and cut the target bone tissue. It can be widely used in precise and high-risk orthopedic surgeries and is suitable for the clinical needs of multiple departments.

[0003] Because the temperature of the transducer affects its resonant point, the ultrasonic bone scalpel requires cooling water to cool the transducer and the scalpel head, thus maintaining a relatively stable temperature for the system. Currently, the transducer cooling water is often adjusted by the user using a speed setting, with the user adjusting the water volume according to their own habits or experience.

[0004] However, it is difficult to adjust the water flow rate of the transducer in a timely manner to match the temperature of the transducer by manually adjusting the water flow rate. This results in inaccurate adjustment of the water flow rate. Insufficient water flow rate will cause the transducer to heat up continuously, which will affect the stability of the ultrasonic bone scalpel and the life of the transducer, leading to the breakage of the ultrasonic bone scalpel and a sharp reduction in the life of the transducer.

[0005] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is prior art. Summary of the Invention

[0006] The main objective of this application is to provide a transducer temperature control method and system, and a readable storage medium, which aims to solve the technical problem of low accuracy in manually adjusting water flow rate by the user.

[0007] To achieve the above objectives, this application provides a transducer temperature control method applied to the transducer of an ultrasonic bone scalpel system. The transducer is provided with a water injection channel, and the outer shell of the transducer is provided with a first temperature sensor and a second temperature sensor for detecting the temperature of the transducer. The transducer temperature control method includes the following steps:

[0008] Obtain the first temperature detected by the first temperature sensor and the second temperature detected by the second temperature sensor;

[0009] Based on the first temperature and the second temperature, the water flow rate through the water injection channel of the transducer is adjusted to regulate the temperature of the transducer.

[0010] Further, the step of adjusting the water flow rate through the water injection channel corresponding to the transducer based on the first temperature and the second temperature to adjust the temperature of the transducer includes:

[0011] Obtain the temperature difference corresponding to the first temperature and the second temperature;

[0012] Obtain the target water flow rate corresponding to the temperature difference, and obtain the current water flow rate corresponding to the transducer;

[0013] The water flow rate through the transducer is adjusted based on the target water flow rate and the current water flow rate.

[0014] Furthermore, the step of adjusting the water flow rate corresponding to the transducer based on the target water flow rate and the current water flow rate includes:

[0015] If the target water flow rate is greater than the current water flow rate and less than or equal to the maximum water flow rate corresponding to the transducer, then the water flow rate corresponding to the transducer is adjusted based on the target water flow rate.

[0016] Furthermore, the transducer temperature control method further includes:

[0017] If the target water flow rate is greater than the maximum water flow rate corresponding to the transducer, the working state of the piezoelectric ceramic sheet of the transducer is obtained based on the temperature difference.

[0018] If the operating state is a stable operating state, the excitation frequency of the transducer is adjusted based on the temperature difference.

[0019] Furthermore, after the step of obtaining the first temperature corresponding to the first temperature sensor and the second temperature corresponding to the second temperature sensor, the method further includes:

[0020] Obtain the temperature difference corresponding to the first temperature and the second temperature;

[0021] Based on the temperature difference, the excitation frequency corresponding to the transducer is adjusted.

[0022] Furthermore, the step of adjusting the excitation frequency of the transducer based on the temperature difference includes:

[0023] Based on the temperature difference, determine the resonant point offset corresponding to the current transducer;

[0024] Based on the resonant point offset, the excitation frequency corresponding to the transducer is adjusted.

[0025] In addition, to achieve the above objectives, this application also provides a transducer temperature control system, the system comprising: a transducer, a memory connected to the transducer, a processor, and a transducer temperature control program stored in the memory and executable on the processor, wherein the transducer temperature control program, when executed by the processor, implements the steps of the aforementioned transducer temperature control method.

[0026] Furthermore, the first temperature sensor and the second temperature sensor are disposed on the inner wall of the housing, with the first temperature sensor near one end of the piezoelectric ceramic sheet in the transducer and the second temperature sensor near the other end of the piezoelectric ceramic sheet.

[0027] Furthermore, both the first temperature sensor and the second temperature sensor are low-temperature thin-film sensors.

[0028] In addition, to achieve the above objectives, this application also provides a computer-readable storage medium storing a transducer temperature control program, which, when executed by a processor, implements the steps of the aforementioned transducer temperature control method.

[0029] This application obtains a first temperature detected by the first temperature sensor and a second temperature detected by the second temperature sensor; then, based on the first and second temperatures, it adjusts the water flow rate through the transducer, thereby achieving automatic adjustment of the transducer water flow rate. This reduces the need for manual adjustment by the user, improves the intelligence of the ultrasonic bone scalpel water flow rate adjustment, and reduces the transducer's heating rate by automatically adjusting the water flow rate according to the temperature changes of the transducer's environment detected by the temperature sensors. This improves the stability of the transducer's temperature state, thereby enhancing the stability of the ultrasonic bone scalpel and the transducer's service life. Attached Figure Description

[0034] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0035] Figure 1 This is a schematic diagram of the transducer temperature control system in the hardware operating environment involved in the embodiments of this application; Figure 3 This is a schematic diagram of the transducer structure of this application.

[0036] The transducer temperature control system in this embodiment is applied to an ultrasonic bone scalpel system. For example... Figure 1 Combination Figure 3 As shown, the transducer temperature control system may include: a transducer, a processor 1001 connected to the transducer (e.g., a CPU), a network interface 1004, a user interface 1003, a memory 1005, and a communication bus 1002. The communication bus 1002 is used to enable communication between these components. The user interface 1003 may include a display screen and an input unit such as a keyboard; optionally, the user interface 1003 may also include a standard wired interface or a wireless interface. The network interface 1004 may optionally include a standard wired interface or a wireless interface (e.g., a Wi-Fi interface). The memory 1005 may be a high-speed RAM or a stable, non-volatile memory, such as a disk drive. Optionally, the memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0037] Those skilled in the art will understand that Figure 1 The terminal structure shown does not constitute a limitation on the transducer temperature control system and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0038] like Figure 1 As shown, the memory 1005, which serves as a storage medium, may include an operating system, a network communication module, a user interface module, and a transducer temperature control program.

[0039] exist Figure 1 In the transducer temperature control system shown, the network interface 1004 is mainly used to connect to the backend server and communicate data with the backend server; the user interface 1003 is mainly used to connect to the client (user end) and communicate data with the client; and the processor 1001 can be used to call the transducer temperature control program stored in the memory 1005.

[0040] In this embodiment, the transducer temperature control system includes: a transducer, a memory 1005 connected to the transducer, a processor 1001, and a transducer temperature control program stored in the memory 1005 and executable on the processor 1001. When the processor 1001 calls the transducer temperature control program stored in the memory 1005, it executes the steps of the transducer temperature control method in the following embodiments.

[0041] This application also provides a transducer control method, referring to... Figure 2 , Figure 2 This is a flowchart illustrating the first embodiment of the transducer control method of this application.

[0042] In this embodiment, as Figure 3 As shown, the transducer temperature control method is applied to the transducer of the ultrasonic bone scalpel system. The transducer is provided with a water injection channel, and the outer shell 10 of the transducer is provided with a first temperature sensor 11 and a second temperature sensor 12.

[0043] The water injection channel can be located inside the transducer, for example, it can run through the central axis of the transducer; alternatively, it can be located outside the transducer, for example, a channel running along the axial direction of the transducer between the main body of the transducer and the inner wall of the outer shell. Both the first temperature sensor 11 and the second temperature sensor 12 are low-temperature thin-film sensors with a temperature range of -40 to 105 degrees Celsius, suitable for water-cooling systems. Furthermore, the low-temperature thin-film sensor has a thickness of 0.5 mm, allowing it to be attached or snapped onto the transducer housing 10 for easy installation and fixation.

[0044] The first temperature sensor 11 and the second temperature sensor 12 are disposed on the inner wall of the transducer housing 10. For example, the first temperature sensor 11 and the second temperature sensor 12 can be directly attached or snapped onto the inner wall of the housing 10. The first temperature sensor 11 is close to one end of the piezoelectric ceramic sheet in the transducer, and the second temperature sensor 12 is close to the other end of the piezoelectric ceramic sheet. That is, the first temperature sensor 11 and the second temperature sensor 12 are disposed at positions on the inner wall corresponding to the two ends of the piezoelectric ceramic sheet, and there is a certain distance between the first temperature sensor 11 and the second temperature sensor 12. Since the housing 10 is cylindrical, the position in the housing 10 corresponding to the piezoelectric ceramic sheet is a cylinder. The first temperature sensor 11 and the second temperature sensor 12 can be disposed at the two ends of the cylinder, or the first temperature sensor 11 and the second temperature sensor 12 can be disposed at the two ends of the diagonal of the cylinder, respectively.

[0045] The transducer temperature control method includes the following steps:

[0046] Step S101: Obtain the first temperature detected by the first temperature sensor and the second temperature detected by the second temperature sensor;

[0047] Step S102: Based on the first temperature and the second temperature, adjust the water flow rate through the water injection channel to the transducer to adjust the temperature of the transducer.

[0048] In this embodiment, when the ultrasonic bone scalpel system is running, the detection results of the first temperature sensor and the second temperature sensor can be acquired in real time or at regular intervals to obtain the first temperature and the second temperature.

[0049] After obtaining the first temperature and the second temperature, the water flow rate of the transducer is adjusted based on these temperatures, that is, the inlet water flow rate of the cooling water system in the transducer is adjusted. Specifically, the temperature difference between the first temperature and the second temperature can be calculated first. This temperature difference reflects the cooling efficiency of the heat exchanger. Then, the water flow rate corresponding to the transducer can be adjusted based on this temperature difference. For example, the water flow rate corresponding to each preset temperature difference range can be preset. After obtaining the temperature difference, the preset temperature difference range to which the temperature difference belongs is determined, and the water flow rate corresponding to the preset temperature difference range to which the temperature difference belongs is obtained. The water flow rate flowing through the transducer is adjusted based on the water flow rate corresponding to the preset temperature difference range to which the temperature difference belongs. That is, the water flow rate corresponding to the preset temperature difference range to which the temperature difference belongs is set as the current inlet water flow rate of the transducer.

[0050] The transducer temperature control method proposed in this embodiment acquires a first temperature detected by the first temperature sensor and a second temperature detected by the second temperature sensor. Then, based on the first and second temperatures, it adjusts the water flow rate through the transducer, thereby achieving automatic adjustment of the transducer water flow rate. This reduces the need for manual adjustment by the user, improves the intelligence of the ultrasonic bone scalpel water flow rate adjustment, and reduces the transducer's heating rate by automatically adjusting the water flow rate according to the temperature changes of the transducer's environment detected by the temperature sensors. This improves the stability of the transducer's temperature state, thereby enhancing the stability of the ultrasonic bone scalpel and extending the transducer's service life.

[0051] Based on the first embodiment, a second embodiment of the transducer temperature control method of this application is proposed. In this embodiment, step S102 includes:

[0052] Step S201: Obtain the temperature difference corresponding to the first temperature and the second temperature;

[0053] Step S202: Obtain the target water flow rate corresponding to the temperature difference, and obtain the current water flow rate corresponding to the transducer;

[0054] Step S203: Adjust the water flow rate through the transducer based on the target water flow rate and the current water flow rate.

[0055] In this embodiment, after obtaining the first temperature and the second temperature, the temperature difference between the first temperature and the second temperature is calculated. This temperature difference can reflect the cooling efficiency of the heat exchanger, and the water flow rate through the heat exchanger can be adjusted by the temperature difference.

[0056] After obtaining the temperature difference between the first temperature and the second temperature, the target water flow rate corresponding to the temperature difference is obtained. For example, the water flow rate corresponding to each preset temperature difference range can be preset. After obtaining the temperature difference, the preset temperature difference range to which the temperature difference belongs is determined, and the water flow rate corresponding to the preset temperature difference range to which the temperature difference belongs is obtained as the target water flow rate. At the same time, the current water flow rate corresponding to the transducer is obtained, which can be obtained through the transducer's cooling water system.

[0057] After obtaining the current water flow rate and the target water flow rate, the water flow rate corresponding to the transducer is adjusted based on the target water flow rate and the current water flow rate. Specifically, it is determined whether the target water flow rate is greater than the current water flow rate. If the target water flow rate is greater than the current water flow rate, it is determined whether the target water flow rate is greater than the maximum water flow rate corresponding to the transducer. The maximum water flow rate can be the water flow rate corresponding to the maximum setting of the transducer cooling water system. If the target water flow rate is less than or equal to the maximum water flow rate corresponding to the transducer, the current water flow rate of the transducer is adjusted based on the target water flow rate, that is, the current water flow rate of the transducer is adjusted to the target water flow rate to achieve automatic adjustment of the transducer water flow rate, improve the intelligence of the ultrasonic bone scalpel water flow rate adjustment, and by automatically adjusting the water flow rate according to the temperature difference, the adjusted water flow rate is matched with the current working state of the transducer to reduce the heating rate of the transducer, improve the stability of the transducer temperature state, and thus improve the stability of using the ultrasonic bone scalpel and the service life of the transducer.

[0058] Furthermore, in one possible implementation, step S203 includes:

[0059] Step S2031: If the target water flow rate is greater than the current water flow rate and less than or equal to the maximum water flow rate corresponding to the transducer, then adjust the water flow rate corresponding to the transducer based on the target water flow rate.

[0060] In this embodiment, after obtaining the current water flow rate and the target water flow rate, it is determined whether the target water flow rate is greater than the maximum water flow rate corresponding to the transducer. The maximum water flow rate can be the water flow rate corresponding to the maximum setting of the transducer cooling water system. If the target water flow rate is less than or equal to the maximum water flow rate corresponding to the transducer, the transducer is adjusted based on the target water flow rate, that is, the water flow rate of the transducer is adjusted to the target water flow rate, so as to realize the automatic adjustment of the transducer water flow rate, improve the intelligence of the ultrasonic bone scalpel water flow rate adjustment, and make the water flow rate matched with the current working state of the transducer by automatically adjusting the water flow rate according to the temperature difference, so as to reduce the heating rate of the transducer, improve the stability of the temperature state of the transducer, and thus improve the stability of the ultrasonic bone scalpel and the service life of the transducer.

[0061] Furthermore, in one possible implementation, the transducer temperature control method further includes:

[0062] Step S204: If the target water flow rate is greater than the maximum water flow rate corresponding to the transducer, the working state of the piezoelectric ceramic sheet of the transducer is obtained based on the temperature difference.

[0063] Step S205: If the working state is a stable working state, then adjust the excitation frequency corresponding to the transducer based on the temperature difference.

[0064] In this embodiment, the working state of the piezoelectric ceramic sheet of the transducer corresponding to each preset temperature difference range can be preset. After obtaining the temperature difference, if the target water flow rate is greater than the maximum water flow rate corresponding to the transducer, the preset temperature difference range to which the temperature difference belongs is determined, and the working state of the piezoelectric ceramic sheet corresponding to the preset temperature difference range to which the temperature difference belongs is obtained and used as the working state of the piezoelectric ceramic sheet of the transducer corresponding to the temperature difference.

[0065] After obtaining the operating state of the piezoelectric ceramic element of the transducer, if the operating state is stable, the excitation frequency of the transducer is adjusted based on the temperature difference. Specifically, the excitation frequency of the transducer corresponding to each preset temperature difference range can be preset. After obtaining the preset temperature difference range to which the temperature difference belongs, the excitation frequency corresponding to the preset temperature difference range to which the temperature difference belongs is obtained, and the excitation frequency of the transducer is adjusted based on the excitation frequency corresponding to the preset temperature difference range to which the temperature difference belongs. It is easy to understand that by adjusting the excitation frequency of the transducer, the transducer can still operate at the current actual frequency resonance point after a temperature rise, thereby ensuring the operating state and durability of the transducer.

[0066] The transducer temperature control method proposed in this embodiment obtains the temperature difference between the first temperature and the second temperature; then obtains the target water flow rate corresponding to the temperature difference and the current water flow rate corresponding to the transducer; and then adjusts the water flow rate through the transducer based on the target water flow rate and the current water flow rate, thereby realizing automatic adjustment of the transducer water flow rate, improving the intelligence of ultrasonic bone scalpel water flow rate adjustment. By automatically adjusting the water flow rate according to the temperature difference, the adjusted water flow rate is matched with the current working state of the transducer, thereby reducing the heating rate of the transducer, improving the stability of the transducer temperature state, and thus improving the stability of using the ultrasonic bone scalpel and the service life of the transducer.

[0067] Based on the first embodiment, a third embodiment of the transducer temperature control method of this application is proposed. In this embodiment, after step S101, the transducer temperature control method further includes:

[0068] Step S301: Obtain the temperature difference corresponding to the first temperature and the second temperature;

[0069] Step S302: Based on the temperature difference, adjust the excitation frequency corresponding to the transducer.

[0070] In this embodiment, after obtaining the first temperature and the second temperature, the temperature difference between the first temperature and the second temperature is calculated. This temperature difference can reflect the working state of the piezoelectric ceramic sheet in the transducer.

[0071] After obtaining the temperature difference, the excitation frequency of the transducer is adjusted based on the temperature difference. The operating state of the piezoelectric ceramic element of the transducer corresponding to each preset temperature difference range can be preset. After obtaining the temperature difference, the preset temperature difference range to which the temperature difference belongs is determined, and the operating state of the piezoelectric ceramic element corresponding to that preset temperature difference range is obtained. The excitation frequency of the transducer corresponding to each preset temperature difference range can be preset. After obtaining the preset temperature difference range to which the temperature difference belongs, the excitation frequency corresponding to that preset temperature difference range is obtained, and the excitation frequency of the transducer is adjusted based on the excitation frequency corresponding to that preset temperature difference range. This adjustment of the transducer's excitation frequency through temperature difference ensures that the transducer operates at the current actual frequency resonance point, thereby guaranteeing the transducer's operating state and durability.

[0072] It should be noted that as the temperature of the transducer increases, the resonant frequency of the ultrasonic bone scalpel gradually decreases. Therefore, by adjusting the excitation frequency of the transducer, the ultrasonic bone scalpel can be made to operate at the current actual frequency resonant point.

[0073] Furthermore, in one possible implementation, step S302 includes:

[0074] Step S3021: Based on the temperature difference, determine the resonant point offset corresponding to the current transducer;

[0075] Step S3022: Adjust the excitation frequency corresponding to the transducer based on the resonant point offset.

[0076] In this embodiment, after obtaining the temperature difference, the resonant point offset corresponding to the current transducer is determined based on the temperature difference. Specifically, the target resonant frequency corresponding to the transducer can be determined through the temperature difference, and the current operating frequency of the transducer can be obtained. The corresponding resonant point offset is determined based on the current operating frequency and the target resonant frequency. For example, the resonant point offset = current operating frequency - target resonant frequency. Alternatively, the target resonant frequency can be determined by combining the first temperature and the first temperature difference between the first temperature and the temperature detected by the first temperature sensor at the previous moment, or the second temperature and the second temperature difference between the second temperature sensor at the previous moment.

[0077] After obtaining the resonant point offset, the excitation frequency corresponding to the transducer is adjusted based on the resonant point offset. For example, the frequency corresponding to the resonant point offset is reduced based on the current operating frequency of the transducer so that the operating frequency of the transducer after adjustment is the target resonant frequency. By adjusting the excitation frequency corresponding to the transducer, the ultrasonic bone scalpel is made to work at the current actual frequency resonant point.

[0078] The transducer temperature control method proposed in this embodiment obtains the temperature difference between the first temperature and the second temperature; then, based on the temperature difference, it adjusts the excitation frequency corresponding to the transducer. By adjusting the excitation frequency corresponding to the transducer through the temperature difference, the ultrasonic bone scalpel works at the current actual frequency resonance point, thereby ensuring the working state and durability of the transducer.
