Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to an intelligent orthopedic external support system. Background Art

[0002] After installation, the existing orthopedic external support system requires repeated X-ray and CT examinations to assist in determining whether the patient has achieved bone healing. The patient needs to go to the hospital for multiple examinations, which involves issues such as labor costs, time costs, economic costs, and radiation hazards. In addition, the existing orthopedic external support system lacks records and feedback on its own position and stress after installation, as well as the patient's limb movements, rehabilitation exercise time, rest time, and supine time. Summary of the invention

[0003] The present invention aims to provide an orthopedic intelligent external orthopedic support system, which can accurately determine whether the patient has achieved bone fusion without X-ray or CT examination, increase the accuracy of bone fusion determination, and record and feedback the position and stress of the intramedullary nail after implantation. The present invention can be used for diseases such as limb and pelvic fractures, infections, tumors, and operations such as bone transport, limb lengthening, and external fixation.

[0004] To achieve the above object, the present invention is implemented by adopting the following technical solutions:

[0005] The intelligent orthopedic external support system disclosed in the present invention includes a support rod, which includes an upper section, an elastic section and a lower section of the support rod that are axially connected in sequence. The elastic deformation direction of the elastic section is the axial direction of the support rod. The elastic section is arranged with a stress sensor and a displacement sensor. The support rod is laterally provided with nails or needles.

[0006] Furthermore, there are at least two support rods, and each support rod is transversely connected to at least one other support rod via a nail or a needle.

[0007] Furthermore, a stress sensor and a displacement sensor are provided at the connection portion between the nail or needle and the bracket rod.

[0008] Preferably, the upper section of the support rod and the lower section of the support rod are both connected with nails or needles.

[0009] Preferably, the elastic section includes a spring, a spring sheet or a cross spring sheet.

[0010] Preferably, the elastic section is retractable, and the retractable direction of the elastic section is the axial direction of the support rod.

[0011] Preferably, the elastic section comprises an upper elastic section and a lower elastic section, and a telescopic adjustment mechanism is provided between the upper elastic section and the lower elastic section.

[0012] Preferably, the telescopic adjustment mechanism is a rack and pinion adjustment mechanism.

[0013] Furthermore, the present invention also includes an intelligent terminal, and the stress sensor and the displacement sensor are both wirelessly connected to the intelligent terminal.

[0014] Furthermore, the support rod is provided with a gravity sensor, and the gravity sensor is wirelessly connected to the smart terminal.

[0015] The working principle of the present invention is as follows:

[0016] When the orthopedic external support system is installed, the body's gravity will compress the orthopedic external support system, causing the elastic segment to deform. The stress sensor records the magnitude of the stress and transmits it to the connected smart terminal, which the doctor can observe in the doctor's APP.

[0017] When the patient moves, such as when the body changes posture, the elastic segment will deform again, and the connection between the bracket rod and the nail or needle will undergo micro-motion, resulting in displacement and corresponding changes in stress; the micro-motion and displacement will be recorded by the displacement sensor and stress sensor and transmitted to the smart terminal; the change in posture causes the change in the direction of gravity, which will be recorded by the gravity sensor and transmitted to the smart terminal.

[0018] When the patient has not yet achieved bone healing, the patient's gravity is mainly transmitted through the orthopedic external support system, and the stress is mainly concentrated in the orthopedic external support system (one of the main functions of the orthopedic external support system is support). When people move and change their postures, stress changes, micro-motions and displacements will occur, and the direction of gravity will also change. When the bone heals, bone healing is like a component in a cavity inside the concrete. It does not bear stress, does not produce micro-motions and displacements, but there are still changes in the direction of gravity. At this time, the displacement sensor records a value of 0, and the stress recorded by the stress sensor is fixed at a lower value. At this time, the doctor can judge whether the patient has achieved intervertebral fusion and whether he has fully recovered after surgery by recording the stress and displacement curves, thereby avoiding repeated radiation exposure such as X-rays and CT.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. The present invention can intelligently judge whether bone healing has been achieved, avoid the radiation hazards of traditional X-ray and CT radiological methods, reduce the time, manpower and economic costs incurred by both doctors and patients, and reduce the social medical burden.

[0021] 2. The present invention completes the longitudinal elastic design, increases the stress stimulation of the fracture ends, and is beneficial to early recovery.

[0022] 3. The present invention adds a longitudinal adjustment device, which can adjust the spacing and stress of the fracture ends through the knob, and can achieve rapid adjustment of stress and spacing, thereby promoting bone healing of the fracture ends; the spacing adjustment is particularly suitable for bone transport and bone lengthening surgery, which is more convenient and simple.

[0023] 4. Added digital intelligent display of spacing and stress.

[0024] 5. The data recorded by stress sensors, displacement sensors, and gravity sensors will be automatically analyzed and converted into curves by the mobile phone APP, so as to analyze the patient's activity level, activity time, supine time, rehabilitation training time and other patient data for doctors to better guide patients' rehabilitation exercises.

[0025] 6. The present invention can accurately determine whether the patient's bone healed, and increase the accuracy of fusion determination (the accuracy of existing X-ray and CT in determining fusion is low, only about 50-70%).

[0026] 7. The present invention can be used by pregnant women, people preparing for pregnancy, and other people who are sensitive to radiation hazards (pregnant women and people preparing for pregnancy are often in an awkward dilemma because they are worried about radiation hazards and have diseases that require orthopedic surgery).
