Therefore, the technical problems that materials and matched sensors in the related technology are complex in preparation process and high in cost, and therefore popularization and application are not facilitated are solved.

Specifically, fig. 1 is a schematic structural diagram of an orthopedic bone plate according to an embodiment of the present invention.

As shown in fig. 1, the orthopedic plate 10 includes: the bone plate comprises a bone plate body 101, a communication unit 102 and a packaging body 103.

Specifically, the bone plate body 101 is made of a predetermined material at a predetermined position thereof in a predetermined manner to sense a pressure thereon and output a strain signal.

In the actual implementation process, the embodiment of the invention can obtain the mechanical signal of the fracture or the affected part position in a contact type strain sensing mode to form a mechanical feedback mechanism, and particularly can fix the bone fracture plate body 101 at the fracture position as strain sensing equipment to sense the pressure on the implanted position so as to output the strain signal.

The bone plate body 101 provided by the embodiment of the invention can be made of preset materials in a preset mode, so that corresponding sensor equipment is not needed, the preparation process is simplified, and the cost is reduced.

Optionally, in an embodiment of the invention, the predetermined position is a position corresponding to the fracture end.

It can be understood that in the bone healing process, monitoring of the mechanical environment of the fracture or the affected part is an important basis for influencing the subsequent treatment and rehabilitation intervention after the fracture operation, and particularly, monitoring of the stress-strain condition at the fracture end can directly reflect the bone healing state, so that the preset position of the bone fracture plate body 101 of the embodiment of the invention can be the position corresponding to the fracture end, thereby facilitating real-time monitoring of the stress-strain condition at the fracture end, facilitating subsequent analysis of the in-vivo state of the bone fracture plate body 101 and healing process evaluation, and timely changing the behavior of the patient to guide the rehabilitation training of the patient.

In some embodiments, the preset material of the bone plate body 101 may be carbon fiber reinforced polyetheretherketone, wherein the carbon fiber reinforced polyetheretherketone is a carbon fiber reinforced polyetheretherketone composite material, which concentrates the advantages of polyetheretherketone materials and carbon fiber materials, has light weight, excellent mechanical properties, chemical corrosion resistance and biocompatibility, and the material may have high conductivity and stress response characteristics after being carbonized by a high-energy laser beam, and the resin matrix has less electromagnetic interference, which provides possibility for directly converting the intramedullary nail itself into a sensing device.

For example, in the embodiment of the present invention, the conductive region with a corresponding shape is directly processed on the carbon fiber reinforced polyetheretherketone by using laser through a radiation carbonization method, so that the polyetheretherketone material is modified to sense a mechanical signal, a temperature signal, or a chemical signal in vivo.

The laser irradiation can adopt ultraviolet light, visible light and infrared light, the pulse width can be millisecond, nanosecond, picosecond, femtosecond and the like, and the required conductive area can be carbonized on the surface of the carbon fiber reinforced polyether-ether-ketone. In addition, the embodiment of the invention can change the energy density of the laser by changing the laser parameters such as the output power, the scanning speed, the repetition frequency, the defocusing amount and the like of the laser, further change the appearance, the components, the resistivity and the like of the conductive area, and simultaneously can carry out pattern design on the carbonized conductive layer (carbonized layer) by designing the laser processing track to form different patterns and be suitable for sensors for composite signal sensing of mechanics (pressure, strain, friction and the like), temperature, chemistry (pH and the like).

For example, the laser irradiation may be ultraviolet nanosecond laser, the output power of the laser may be 5W-10W, such as 5W, 6W, 7W, 8W, 9W, 10W, etc., the repetition frequency may be 40kHz-100kHz, such as 40kHz, 50kHz, 60kHz, 70kHz, 80kHz, 90kHz, 100kHz, etc., the scanning speed may be 20-110mm/s, such as 20mm/s, 30mm/s, 40mm/s, 50mm/s, 60mm/s, 70mm/s, 80mm/s, 90mm/s, 100mm/s, 110mm/s, etc., and the defocus amount may be 2-10mm, such as 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, etc. Therefore, the energy density irradiated on the surface of the carbon fiber reinforced polyether-ether-ketone matrix is larger than 0.83J/mm < 2 >, and a carbonization layer can be formed on the surface of the carbon fiber reinforced polyether-ether-ketone matrix.

Optionally, in one embodiment of the invention, the bone plate body 101 includes at least one of a neutralization plate, a support plate, a cleat plate, and a bridge plate.

And the communication unit 102 is used for receiving the strain signal and sending the strain signal to a preset terminal so as to obtain stress-strain data of the fracture end during the fracture healing period of the human body based on the strain signal.

As a possible implementation manner, the embodiment of the invention may implement signal transmission through the communication unit 102, wherein the communication unit 102 may receive the strain signal output by the bone fracture plate body 101, and transmit the strain signal to a preset terminal, such as a signal receiver, through wireless transmission, so as to convert the strain signal into stress-strain data of a fracture end during the healing of the human fracture. The wireless transmission can be performed in various manners, such as a wired active manner, a wireless passive manner, and the like, which are described in detail below.

Specifically, when the preset material of the bone plate body 101 is carbon fiber reinforced polyetheretherketone and the preset manufacturing method is an irradiation carbonization method, in the embodiment of the invention, in-situ carbonization of the surface of a carbon fiber reinforced polyetheretherketone substrate is realized by irradiation carbonization, carbide layers with different shapes are formed as radio frequency tags, the different shapes have corresponding characteristic frequencies, after strain is monitored, the resonance frequency is correspondingly changed, real-time monitoring of stress strain is realized, and the problem of obvious increase of the resonance response frequency is avoided because the combination between the radio frequency tags and the substrate is very firm and cannot be infirm along with the time extension.

The radio frequency tag on the carbon fiber reinforced polyether-ether-ketone substrate can be in various shapes, and different shapes can produce different effects, for example, the radio frequency tag can be in a thin strip shape, is more sensitive to mechanical signals, and can accurately and timely respond to the mechanical signals so as to be used for feeding back the mechanical signals, such as stress, strain and the like; the radio frequency tag can be a bent connection structure with a plurality of slender lines, and the structure can sense slight temperature change so as to be used for feeding back a temperature signal; the rf tag may be square and may be used to feed back chemical signals, such as changes in pH in the body, by absorbing the fluid components and sensing changes in the fluid. In the post-operation healing stage, the embodiment of the invention can obtain the mechanical signal of the fracture end in the body in a wireless communication mode, and is used for analyzing the prognosis condition of the patient operation, for example, when the preset terminal is close to the radio frequency tag on the bone fracture plate 10, a corresponding peak value can appear at the resonant frequency of the tag, and a person skilled in the art can calculate the stress state of the bone fracture plate 10 by analyzing the frequency, the kurtosis and other information of the peak, thereby evaluating the bone healing condition and realizing the radio frequency wireless communication.

In the laboratory research stage, because the device does not need to be implanted into a human body, for example, the device can be directly connected to a Personal Computer (PC) end through a data line for display, the embodiment of the invention can adopt a wired mode for data testing, calibration and evaluation, and is convenient for debugging equipment.
