Example 1
The embodiment provides an intelligent implant, as shown in fig. 1, where the intelligent implant is packaged in a housing, and includes an attitude sensor, an MCU (micro control chip), a clock chip, a communication module, a power module, and the like.
The gesture sensor is used for detecting gesture information (including x, y, z acceleration information, angle information and the like) of the joint relative to the ground and transmitting the detected gesture information to the micro-control chip.
The micro control chip is used for reading real-time information from the clock chip, adding a time tag to the received acceleration information, and then transmitting the acceleration information added with the time tag to the external terminal equipment through the communication module.
The power module is used for supplying power to the attitude sensor, the micro-control chip, the clock chip and the communication module.
The power module of the embodiment may be a disposable battery, a rechargeable battery, a super capacitor, or the like; if the power module is a rechargeable battery or a super capacitor, the intelligent implant further comprises a charging module, and the charging module can be based on electromagnetic induction charging, ultrasonic charging, spontaneous human body charging and the like.
The communication module of the present embodiment includes, but is not limited to, bluetooth, radio frequency, ultrasonic, electromagnetic wave communication modules.
The intelligent implant of the embodiment communicates with an external terminal through a communication module. The external terminal of the embodiment adopts but is not limited to electronic terminal equipment such as a computer, a mobile phone and the like.
The intelligent implant of this embodiment theory of operation is:
the method comprises the steps of detecting the posture information (x, y, z three-way acceleration information and angular velocity information) of a bone segment relative to the ground through a posture sensor, transmitting the posture information to a micro-control chip, acquiring real-time information from a clock chip by the micro-control chip, adding a time tag to the posture information, and transmitting the posture information with the time tag to external terminal equipment through a communication module for further analysis and processing so as to realize the functions of joint posture detection, activity detection, bone healing judgment, iteration alarm and the like.
Example 2
This embodiment employs an intelligent implant as set forth in embodiment 1 above for fall detection or bone implant abnormality detection.
As shown in fig. 2, the intelligent implant of the present embodiment may be used in combination with a shoulder prosthesis, and since the upper body may be maintained relatively upright while a person walks, only one intelligent implant may be provided at the end of the shoulder prosthesis. The intelligent implant can measure the swing amplitude of the arm, detect the activity degree after operation according to the swing angle, count the steps through the swing of the arm, and the like.
In this embodiment, an intelligent implant is adopted, and strict time synchronization is not required, so that a clock chip is not required, and an internal clock of the micro-control chip is utilized. When the human body stands upright and the two arms naturally droop, the external terminal sends an instruction to the implant to control the posture sensor of the implant to be set to zero. Likewise, the implant can also perform a fall alarm function.
The fall detection principle of this embodiment is:
when a human body stands upright, the posture sensor of the intelligent implant can be set to zero through the external terminal, namely, the posture at the moment is taken as a reference posture, and any other posture takes the posture at the moment as a reference. When a human body falls down, the gesture sensor of the intelligent implant can detect sudden rapid acceleration in a certain direction, and the angle of the Z axis is changed from about + -0 DEG to about + -90 DEG when standing, so that the human body is judged to fall down, and at the moment, the external terminal automatically acquires current position information, actively contacts with an emergency contact person or alarms, and simultaneously sends the position information. The function has very obvious beneficial effects on the old and the mental retardation and other groups.
Similarly, as shown in fig. 3, when the intelligent implant of the present embodiment is used in combination with an ankle prosthesis, an intelligent implant is provided at the upper end of the ankle. When the human body stands up, the external terminal sends an instruction to the intelligent implant to control the posture sensor of the intelligent implant to be set to zero.
In this embodiment, the connection between the intelligent implant and the joint prosthesis may be, but not limited to, threaded connection, snap connection, or the like, and only a connection port is preset on the prosthesis.
On the other hand, the intelligent implant of the present embodiment may also be mounted on the upper end of the knee prosthesis to perform abnormality detection on the knee prosthesis, specifically: when a human body stands upright, the posture sensor of the intelligent implant can be set to zero through an external terminal, namely, the posture at the moment is taken as a reference posture, and any other posture takes the posture at the moment as a reference; if the measured angle of the knee joint prosthesis where the intelligent implant is located is always biased to a certain direction, the measured angle indicates that the knee joint prosthesis is abnormal, for example, a pad of the knee joint prosthesis is not placed flatly, or a certain side of the knee joint prosthesis is worn greatly due to uneven stress, and the like. Example 3
In this embodiment, two intelligent implants proposed in embodiment 1 are used, as shown in fig. 4, and the two intelligent implants are installed on two adjacent bone segments of a joint, so as to detect the posture of the joint, and perform activity detection and bone healing judgment.
The joint gesture detection working principle of this embodiment is:
the intelligent implants are respectively arranged on two adjacent bone segments of the joint, each intelligent implant can acquire the posture information of the bone segment at the position corresponding to the ground when walking, the external terminal analyzes the posture information of the two intelligent implants to acquire the detection of the relative posture and the activity of the two adjacent bone segments of the joint, for example, the movement included angle, gait and the like of the tibia and the lower limb bone can be analyzed according to the angle information of the two intelligent implants to the ground, and the data support can be provided for the postoperative recovery condition of a patient through gait analysis; or detecting the activity degree of the knee joint after operation through the maximum difference value of the angles of the two intelligent implants.
In this embodiment, two intelligent implants (intelligent implant a and intelligent implant B) may be installed in a knee prosthesis, and the two intelligent implants may be placed on a tibia segment and a lower limb bone segment (as shown in fig. 5) of the knee prosthesis, respectively, so as to perform knee posture detection, and determine conditions such as knee mobility and bone healing.
The knee joint posture detection workflow of the present embodiment is:
the two intelligent implants control the attitude sensor to detect at the same frequency;
when two intelligent implants communicate with the outside, an external terminal (such as a mobile phone, a tablet, or a special communication terminal) transmits the system time to the intelligent implants in real time, the intelligent implants immediately write clock chips after receiving the time information, and the clock chips update the system time in real time, so that the clocks of the connected intelligent implants are ensured to be completely consistent;
the two intelligent implants acquire the posture information of the bone segments corresponding to the ground, real-time information is read from the clock chip, a time tag is added to the posture information, then the posture information with the time tag is transmitted to an external terminal, and after the external terminal receives the posture information of the two intelligent implants, one-to-one mapping and analysis of the two groups of data are realized according to the time tag, as shown in fig. 6.
In this embodiment, the intelligent implant is used to measure the number of steps of walking, and count the number of steps of walking, and it is required to continuously detect the preset number of times and large angle change in unit time, so as to judge the motion state as walking, so as to prevent misjudgment caused by actions such as shaking, small-range swing, etc. during sitting.
Similarly, two intelligent implants (intelligent implant a and intelligent implant B) may also be installed on the acetabular cup and femoral stem ends of the hip joint prosthesis, respectively. The hip joint posture detection, gait analysis, mobility detection, healing detection and the like can be realized, as shown in fig. 7.
In this embodiment, two intelligent implants (intelligent implant a and intelligent implant B) may be used in combination with a wrist prosthesis to implement wrist mobility measurement, healing detection, etc., and step count statistics may be implemented by arm swing, as shown in fig. 8.
In this embodiment, the connection between the intelligent implant and the joint prosthesis may be, but not limited to, threaded connection, snap connection, or the like, and only a connection port is preset on the prosthesis.
The foregoing description of the embodiments has been provided for the purpose of illustrating the general principles of the invention, and is not meant to limit the scope of the invention, but to limit the invention to the particular embodiments, and any modifications, equivalents, improvements, etc. that fall within the spirit and principles of the invention are intended to be included within the scope of the invention.
