Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to a prosthesis monitoring device and system. Background Art

[0002] Prostheses, especially joint prostheses, are widely used in joint replacement surgeries. Joint replacement surgery replaces the artificial joint prosthesis for the joint in the human body that has lost joint function or necrosis. It can replace the corresponding type of joint prosthesis for different joint parts such as the human knee joint, wrist joint, and hip joint. After the artificial joint prosthesis is implanted, it is prone to loosening and / or wear due to improper use by the patient, resulting in the artificial joint prosthesis deviating from the normal installation position, thus affecting the normal activities of the human body. In addition, after the joint prosthesis is installed in the human body, the surrounding human tissues may have an infection or inflammatory reaction due to biological incompatibility, which easily leads to lesions in the surrounding human tissues and also affects the normal activities of the joint prosthesis and its surrounding human tissues. In order to timely detect whether the artificial joint prosthesis has abnormal conditions such as loosening, wear, and infection, it is usually necessary to regularly detect the artificial joint prosthesis to obtain the structural and physiological state information of the artificial joint prosthesis. How to continuously and reliably monitor the artificial joint prosthesis without affecting the normal activities of the patient is of great significance for maintaining the normal operation of the artificial joint prosthesis.

The phrase appears at various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0056] Please refer to Figures 1-4 As shown, a prosthesis monitoring device provided by an embodiment of the present application. The prosthesis monitoring device includes a monitoring device 1, which is disposed in the surrounding area of the prosthesis and is used to monitor the structural state of the prosthesis and / or the physiological state around the prosthesis.

[0057] The monitoring device 1 may include, but is not limited to, at least one ultrasonic sensor 2 and / or at least one temperature sensor 3, a control circuit board 4, a battery 5, and a charging coil 6. Among them, at least one ultrasonic sensor 2 is used to monitor the structural state of the prosthesis, and at least one temperature sensor 3 is used to monitor the physiological state around the prosthesis. When the monitoring device 1 includes multiple ultrasonic sensors 2, the multiple ultrasonic sensors 2 can be distributed at different positions within the monitoring device 1 to perform distributed ultrasonic detection on different positions of the prosthesis accordingly. When the monitoring device 1 includes multiple temperature sensors 3, the multiple temperature sensors can be distributed at different positions within the monitoring device 1 to perform distributed temperature detection on different positions of the prosthesis accordingly.

[0058] The ultrasonic sensor 2 may include, but is not limited to, an ultrasonic transmitting part and an ultrasonic receiving part. The ultrasonic transmitter is used to emit ultrasonic waves to the tissue around the prosthesis, and the ultrasonic receiver is used to receive the ultrasonic echo formed after the ultrasonic waves are reflected by the tissue around the prosthesis. The control circuit board 4 is connected to the ultrasonic sensor 2. The control circuit board 4 can determine the propagation characteristics and echo state characteristics of the ultrasonic waves between the prosthesis and the surrounding tissue based on the ultrasonic waves emitted by the ultrasonic transmitting part and the ultrasonic echo received by the ultrasonic receiving part. Then, based on the propagation characteristics and echo state characteristics, it can determine the relative position state between the prosthesis and the surrounding tissue and / or the surface structure state of the prosthesis.

[0059] Preferably, the control circuit board 4 can determine the change characteristics of the propagation distance, the change characteristics of the echo intensity, and the change characteristics of the frequency energy of the ultrasonic waves between the prosthesis and the surrounding tissue based on the ultrasonic waves emitted by the ultrasonic transmitting part and the ultrasonic waves received by the ultrasonic receiving part. Then, based on the change characteristics of the propagation distance, the change characteristics of the echo intensity, and the change characteristics of the frequency energy, it can determine whether the prosthesis is loose relative to the surrounding tissue and / or whether the surface of the prosthesis is worn.

[0060] The temperature sensor 3 can be, but is not limited to, a semiconductor sensor, which can detect the temperature of the tissue around the prosthesis to obtain the real-time temperature data of the tissue around the prosthesis. The control circuit board 4 is connected to the temperature sensor 3.

Based on the temperature change characteristics, it can determine the physiological state of the tissue around the prosthesis.

[0061] Preferably, the control circuit board 4 can determine the temperature change difference, the temperature change rate, the temperature spatial distribution difference rate, and the high-frequency energy ratio change rate of the tissue around the prosthesis based on the temperature data detected by the temperature sensor. Based on the temperature change difference, the temperature change rate, the temperature spatial distribution difference rate, and the high-frequency energy ratio change rate, it can determine whether an infection has occurred in the tissue around the prosthesis.

[0062] The control circuit board 4 can also control the working states of the ultrasonic sensor 2 and the temperature sensor 3.

Preferably, the control circuit board 4 can adjust the monitoring frequencies of the ultrasonic sensor 2 and the temperature sensor 3 respectively according to the power level of the battery 5; when the real-time power of the battery 5 is less than or equal to the preset power threshold, the monitoring frequencies of the ultrasonic sensor 2 and the temperature sensor 3 are reduced; when the real-time power of the battery 5 is greater than the preset power threshold, the current monitoring frequencies of the ultrasonic sensor 2 and the temperature sensor 3 remain unchanged. This can reduce the impact of the battery power on the operation of the ultrasonic sensor 2 and the temperature sensor 3, enable the ultrasonic sensor 2 and the temperature sensor 3 to continuously monitor the prosthesis, and avoid the interruption of prosthesis monitoring.

[0063] The control circuit board 4 further includes a wireless communication circuit, which sends the monitoring results of the ultrasonic sensor 2 and the temperature sensor 3 to an external detection terminal through the wireless communication circuit; among them, the wireless communication circuit can support different types of wireless communication methods such as WIFI, Bluetooth or NFC. The battery 5 is used to supply power to the ultrasonic sensor 2, the temperature sensor 3, and the control circuit board 4, and can be, but is not limited to, a rechargeable battery.

[0064] The monitoring device 1 further includes a charging coil 6; the charging coil 6 is electrically connected to the battery 5; the charging coil 6 can perform electromagnetic induction with an external excitation coil 18, receive electric energy from the excitation coil 18, and transmit the received electric energy to the battery 5 to charge the battery 5, so as to provide electric energy for the overall stable and continuous operation of the monitoring device 1 and avoid the interruption of the operation of the monitoring device 1. Preferably, the charging coil 6 can be arranged on the outer periphery of the control circuit board 4 and coplanar with the control circuit board 4, so as to reduce the occupied space range of the charging coil 6.

[0065] The monitoring device 1 further includes a packaging member 7, and the ultrasonic sensor 2, the temperature sensor 3, the control circuit board 4, the battery 5, and the charging coil 6 are all arranged inside the packaging member 7, so as to seal and isolate the ultrasonic sensor 2, the temperature sensor 3, the control circuit board 4, the battery 5, and the charging coil 5, avoid being interfered by the external environment, and prevent the penetration of human internal tissue fluid into the inside of the packaging member 7 to cause a short circuit of the monitoring device. The packaging member 7 can be made of a biocompatible plastic material.

[0066] The monitoring device 1 further includes an implanting gasket 8, and the packaging member 7 is embedded in the implanting gasket 8. The monitoring device 1 is stably arranged in the surrounding area of the prosthesis by means of the implanting gasket to realize the monitoring of the prosthesis. Considering that different types of artificial joint prostheses have different outer shapes, the implanting gasket 8 can make the monitoring device 1 fit the prosthesis in terms of outer shape structure, ensure that the monitoring device 1 is stably installed on the prosthesis, and avoid the separation of the monitoring device 1 from the prosthesis and the inability to monitor the prosthesis. The implanting gasket 8 can be made of a biocompatible plastic material.

[0067] Please refer to Figure 4 As shown, the prosthesis includes a first sub-prosthesis 11 and a second sub-prosthesis 12 located at the upper end and the lower end respectively, and the monitoring device 1 is arranged between the first sub-prosthesis 11 and the second sub-prosthesis 12. Correspondingly Figure 4 in this case, the prosthesis can be an articular prosthesis arranged between the femur 13 and the tibia 14, and the first sub-prosthesis 11 and the second sub-prosthesis 12 of the prosthesis are a femoral condyle prosthesis and a tibial tray prosthesis respectively. Among them, the femoral condyle prosthesis is arranged on the distal end of the femur 13 and is connected to the distal end of the femur 13 by bone cement; the tibial tray prosthesis is arranged on the proximal end of the tibia 14 and is connected to the proximal end of the tibia 14 by bone cement.

[0068] The top and bottom of the implant spacer 8 are respectively provided with a first structural part 9 and a second structural part 10 that match the shapes of the femoral condyle prosthesis and the tibial tray prosthesis. Among them, the first structural part 9 can be but is not limited to a convex structural part, and the second structural part 10 can be but is not limited to a concave structural part. A groove 15 is formed at the bottom of the femoral condyle prosthesis, and the first structural part 9 can be inserted into the groove 15, so that the top of the implant spacer 8 is fixedly connected to the femoral condyle prosthesis. A bump 16 is formed at the bottom of the femoral condyle prosthesis, and the second structural part 10 is engaged with the bump 16, so that the top of the implant spacer 8 is fixedly connected to the tibial tray prosthesis. Among them, the number of the second structural parts 10 can be at least two, and each second structural part 10 is respectively arranged on different edge sides of the top of the tibial tray prosthesis. By engaging different second structural parts 10 with the corresponding bumps 16, the implant spacer 8 is provided with engaging forces from different directions, improving the connection stability between the implant spacer 8 and the tibial tray prosthesis.

[0069] Please refer to Figure 5 As shown, a prosthesis monitoring system provided by an embodiment of the present application. The prosthesis monitoring system includes a prosthesis monitoring device and an external monitoring terminal 17; the prosthesis monitoring device is communicatively connected to the external monitoring terminal 17, and the prosthesis monitoring device can send the monitoring results regarding the structural state of the prosthesis and / or the physiological state around the prosthesis to the external monitoring terminal 17. Among them, the external monitoring terminal 17 can be but is not limited to a terminal such as a computer or a smart phone.

[0070] The external monitoring terminal 17 includes a processor 18 and a display 19. The processor 18 is wirelessly connected to the prosthesis monitoring device and is used to receive the monitoring results of the prosthesis monitoring device; the display 19 is connected to the processor 18 and is used to display the monitoring results. By viewing the display 19, it can be determined whether the prosthesis has abnormal conditions such as loosening, wear, and infection.

[0071] The external monitoring terminal 17 further includes an excitation coil 20. The excitation coil 20 is electrically connected to the processor 18, and the processor 18 is configured to deliver alternating current to the excitation coil 20 to generate an electromagnetic field by the excitation coil 20. When the excitation coil 20 is close to the prosthesis monitoring device, electromagnetic induction occurs between the excitation coil 20 and the charging coil 6 in the prosthesis detection device, and the excitation coil 20 can transmit electric energy to the charging coil 6 to achieve wireless charging of the prosthesis monitoring device. In practical applications, a smart phone with reverse charging function can be used as the external monitoring terminal 17, which facilitates the patient to wirelessly charge the prosthesis monitoring device at any time and place, and wirelessly connect the smart phone to the prosthesis monitoring device and obtain the monitoring structure of the prosthesis monitoring device.

[0072] Further, the prosthesis monitoring device is communicatively connected to the external monitoring system, including:

[0073] Transmitting a wireless signal according to the initial wireless signal strength to control the communication connection between the prosthesis monitoring device and the external monitoring system;

[0074] Monitoring the communication operation parameters between the prosthesis monitoring device and the external monitoring system under the initial wireless signal strength according to a preset wireless communication reference operation duration; wherein, the communication operation parameters include the communication interruption rate and the proportion of the power consumption per unit time in the total power;

[0075] Using the following formula (1), according to the communication interruption rate and the proportion of the power consumption per unit time in the total power, obtaining a wireless signal transmission intensity adjustment coefficient,

[0076]

[0077] In the above formula (1), P represents the wireless signal transmission intensity adjustment coefficient; n represents the number of unit times included in the preset wireless communication reference operation duration; Z represents the communication interruption rate; Z c represents the preset communication interruption rate reference value; W i represents the proportion of the power consumption corresponding to the i-th unit time in the total power;

[0078] Using the following formula (2), according to the wireless signal transmission intensity adjustment coefficient, adjusting the wireless signal intensity corresponding to the wireless signal transmitted by the prosthesis monitoring device,

[0079] B = (1 + P)·B0 (2)

[0080] In the above formula (2), B represents the adjusted wireless signal intensity; B0 represents the initial wireless signal intensity.

[0081] By monitoring the communication interruption rate through a preset duration, the stability of the communication connection can be accurately grasped. If the interruption rate is high, it indicates that the current initial wireless signal strength may not be able to meet the communication requirements. By calculating the adjustment coefficient in combination with the power consumption rate per unit time and then adjusting the wireless signal strength, the probability of communication interruption can be effectively reduced, the stability and reliability of communication can be improved, and it can be ensured that the prosthesis monitoring data can be stably and completely transmitted to the external monitoring system. Dynamically adjusting the wireless signal transmission intensity according to the actually monitored communication operation parameters enables the communication system to make timely responses according to different environments and usage situations. For example, in the case of strong signal interference or long distance, the wireless signal strength is automatically increased; when the wireless signal is good, the strength is reduced, so as to maintain high-quality communication and avoid data loss or transmission delay caused by wireless signal problems. Monitoring the proportion of the power consumption per unit time in the total power, quantifying the power consumption situation, enables the system to clearly understand the energy consumption levels under different wireless signal strengths. This provides a reference from the energy dimension for reasonably controlling the wireless signal strength and avoids unnecessary power consumption caused by excessive enhancement of the wireless signal strength. After adjusting the wireless signal strength according to the adjustment coefficient, the energy consumption of the prosthesis monitoring device can be reduced on the premise of ensuring communication quality. Lower energy consumption means longer battery life and reduces the need for frequent charging or battery replacement. For the prosthesis monitoring device that needs to be worn and used for a long time, it greatly improves the convenience and sustainability of use. In different usage scenarios, such as different indoor areas, outdoor environments, etc., the conditions of wireless communication vary greatly. This technical solution enables the prosthesis monitoring device to adapt to various complex communication environments by real-time monitoring of communication operation parameters and dynamically adjusting the signal transmission intensity, ensuring stable communication connections in different environments and improving the environmental adaptability of the system. This mechanism of automatically adjusting the signal transmission intensity based on actual communication parameters enhances the compatibility of the prosthesis monitoring device with different external monitoring systems. Regardless of how the receiving performance of the external monitoring system changes, the prosthesis monitoring device can adapt through self-adjustment, improving the versatility and practicality of the entire system and expanding its application scope.

[0082] Generally speaking, the prosthesis monitoring device includes monitoring devices arranged in the area around the prosthesis. The monitoring devices include at least one sensor for monitoring the structural state of the prosthesis and / or the physiological state around the prosthesis, and can continuously monitor the relative position and surface structure between the prosthesis and the surrounding tissues, as well as the physiological state of the surrounding tissues in real time during the operation of the prosthesis, and accurately identify abnormal conditions such as loosening, wear and infection that may occur to the prosthesis; the prosthesis monitoring system includes a prosthesis monitoring device and an external monitoring system connected by communication. The external monitoring system can receive and display the monitoring results from the prosthesis monitoring device, facilitating real-time understanding of the actual structural state and / or physiological state of the prosthesis, and timely discovering abnormal conditions such as loosening / wear and infection that may occur to the prosthesis, improving the convenience and efficiency of prosthesis monitoring.
