Technical Field

The invention relates to the field of medical instruments, in particular to an intelligent orthopedic external support system.

Background

The existing orthopedic external support system needs to repeatedly perform X-ray and CT examination after installation to assist in judging whether a patient achieves bone healing or not, and the patient needs to repeatedly go to a hospital to perform multiple examinations, so that the problems of labor cost, time cost, economic cost, radiation hazard and the like are solved. In addition, the existing orthopedic external support system lacks recording and feedback on the self position and stress condition after installation, the limb movement, the rehabilitation exercise time, the rest time, the lying time and the like of the patient.

Disclosure of Invention

The invention aims to provide an intelligent orthopedic external support system for accurately judging whether a patient achieves bone fusion or not under the condition of not carrying out X-ray and CT (computed tomography) examination, so that the accuracy of bone fusion judgment is increased, and the self position, the stress condition and the like of an implanted intramedullary nail can be recorded and fed back. The invention can be used for the treatment of fracture, infection, tumor and other diseases of limbs and pelvis, and the operation of bone transportation, limb extension, external fixation and the like.

In order to achieve the purpose, the invention is realized by adopting the following technical scheme:

the invention discloses an intelligent orthopedic external support system which comprises a support rod, wherein the support rod comprises an upper support rod section, an elastic section and a lower support rod section which are sequentially and axially connected, the elastic deformation direction of the elastic section is the axial direction of the support rod, a stress sensor and a displacement sensor are arranged on the elastic section, and a nail or a needle is transversely arranged on the support rod.

Further, the support rods are at least two, and each support rod is transversely connected with at least one other support rod through a nail or a needle.

Furthermore, a stress sensor and a displacement sensor are arranged at the connecting part of the nail or the needle and the support rod.

Preferably, the upper section of the stent rod and the lower section of the stent rod are both connected with nails or needles.

Preferably, the elastic section comprises a spring, a shrapnel or a crossed shrapnel.

Preferably, the elastic section can stretch and retract, and the stretching direction of the elastic section is the axial direction of the support rod.

Preferably, the elastic section comprises an upper elastic section and a lower elastic section, and a telescopic adjusting mechanism is arranged between the upper elastic section and the lower elastic section.

Preferably, the telescopic adjusting mechanism is a gear and rack adjusting mechanism.

Furthermore, the invention also comprises an intelligent terminal, wherein the stress sensor and the displacement sensor are both in wireless connection with the intelligent terminal.

Further, the support rod is provided with a gravity sensor, and the gravity sensor is in wireless connection with the intelligent terminal.

The working principle of the invention is as follows:

after the orthopedic external support system is installed, due to the existence of human body gravity, the orthopedic external support system is pressed, the elastic section is deformed, the stress sensor records the stress and transmits the stress to the connected intelligent terminal, and a doctor can observe the stress in an APP at the doctor end;

when the patient moves, for example, when the body changes posture, the elastic section can deform again, the connecting part of the bracket rod and the nail or the needle can generate micro-motion to generate displacement, and the stress can also generate corresponding change; the micro-motion and the displacement can be recorded and transmitted to the intelligent terminal by the displacement sensor and the stress sensor; the change of the posture causes the change of the gravity direction, and the gravity sensor records and transmits the change to the intelligent terminal.

When a patient does not achieve bone healing, the gravity of the patient is mainly transmitted through the orthopedic external support system, the stress is mainly concentrated on the orthopedic external support system (one main function of the orthopedic external support system is the supporting function), and when people move and change postures, the stress can be changed, micro motion and displacement can be generated, and the direction of the gravity can be changed. After the bone heals, the bone heals like a component in a cavity inside concrete, does not bear stress, does not produce micromotion and displacement, but still has the direction of gravity changed. The displacement sensor now registers a value of 0 and the stress sensor registers a stress which is fixed at a lower value. At the moment, a doctor can judge whether the patient achieves intervertebral fusion after operation or not and whether the patient is completely recovered or not through the recorded stress and displacement curve, so that repeated radiation irradiation such as X-ray, CT and the like is avoided.

The invention has the following beneficial effects:

1. the invention intelligently judges whether the bone healing is achieved, avoids the radiation hazard of the traditional X-ray and CT radiological methods, reduces the time, labor and economic cost of doctors and patients, and reduces the social medical burden.

2. The invention completes the longitudinal elastic design, increases the stress stimulation of the fracture broken end and is beneficial to early rehabilitation.

3. The invention adds a longitudinal adjusting device, can adjust the spacing and stress of the fracture end through the knob, and can realize the rapid adjustment of the stress and spacing, thereby promoting the healing of the fracture end; the space adjustment is particularly suitable for the bone transportation and bone lengthening operation, and is more convenient and simple.

4. The digital intelligent display of the distance and the stress is increased.

5. Through the data of stress receptor, displacement sensor, gravity sensor record, cell-phone APP can automatic analysis and change into the curve to the analysis reachs patient data such as patient's activity degree, activity time, time of lying, rehabilitation training exercise time and is used for the better recovered exercise of guide patient of doctor.

6. The invention can accurately judge whether the bone of the patient is healed and increase the accuracy of fusion judgment (the accuracy of fusion judgment by the existing X-ray and CT is lower and is only about 50-70%).

7. The invention can be used by pregnant women, pregnant woman preparing personnel and other radiation hazard sensitive personnel (the pregnant women and pregnant woman preparing personnel are often in embarrassing situations because the pregnant women and pregnant woman preparing personnel worry about radiation hazard and are also combined with diseases needing orthopedic surgery).
