Description
Technical Field
The utility model relates to the field of medical equipment, especially, relate to an intelligent orthopedics nail stick internal fixation system.
Background
The existing orthopedic nail-bar system needs to repeatedly perform X-ray and CT examination after being implanted 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 nail-bar system lacks recording and feedback of the self position and stress condition after implantation, the limb movement of the patient, the rehabilitation exercise time, the rest time, the lying time and the like.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an intelligent orthopedics nail stick internal fixation system (can be used to a spinal column way of escape operation, multiple operations such as way of inclining operation) can be under the condition that does not carry out X-ray, CT inspection, and whether accurate judgement patient reaches the bone fusion, increases the rate of accuracy that the bone fusion was judged to self position, stress condition etc. after can implanting the nail stick carry out the record and feed back.
In order to achieve the purpose, the utility model adopts the following technical proposal to realize:
the utility model discloses an intelligent excellent system of nailing, including nail and stick, the one end connective bar of nail, the other end of nail are free end, its characterized in that: the bar comprises a bar body A, an elastic section and a bar body B which are sequentially and axially connected, and a stress sensor and a displacement sensor are arranged in the elastic section.
Preferably, the nail is connected with the rod through a screw, and a stress sensor and a displacement sensor are arranged at the connecting part of the nail and the rod.
Preferably, the rod body A and the rod body B are both connected with a nail, and the nail is perpendicular to the rod.
Preferably, the elastic deformation direction of the elastic section is the axial direction of the rod.
Further, the utility model discloses still include intelligent terminal, stress sensor, displacement sensor all with intelligent terminal wireless connection.
Preferably, the intelligent terminal is a mobile phone.
Furthermore, a gravity sensor is arranged on the stick body A and/or the stick body B, and the gravity sensor is in wireless connection with the intelligent terminal.
Further, a chemical sensor is arranged on the surface of the rod A and/or the surface of the rod B and is in wireless connection with the intelligent terminal.
Preferably, the elastic section comprises a spring, a shrapnel or a crossed shrapnel.
The working principle of the utility model is as follows:
after the orthopedic nail bar internal fixation system is implanted, due to the existence of human body gravity, bones can press the orthopedic nail bar internal fixation system, the elastic part can deform, the stress sensor records the stress and transmits the stress to the connected intelligent terminal, and a doctor can observe the stress in a doctor end APP;
when the patient moves, for example, when the body changes posture, the elastic component can deform again, the connecting parts of the rod A, the rod B and the nail are slightly moved 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 intervertebral orthopedic nail rod internal fixing system, the stress is mainly concentrated on the orthopedic nail rod internal fixing system (one main function of the orthopedic nail rod internal fixing system is the supporting function), and when the patient moves and changes postures, the stress can be changed, micro motion and displacement can be generated, and the gravity direction can be changed. After the intervertebral fusion, the bone connects the upper and lower vertebral bodies to play a role of intervertebral firm support; at this time, the internal fixing system of the orthopedic nail rod is like a component in a hollow hole in concrete, does not bear stress, does not generate micromotion and displacement, but still has the change of the gravity direction. 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 utility model has the advantages as follows:
1. the utility model discloses can realize that self judges intelligently whether reach intervertebral fusion! The radiation hazard of the traditional X-ray and CT radiological method is avoided, the time, labor and economic cost caused by the two parties are reduced, and the social medical burden is reduced;
2. the utility model discloses accomplished vertical elastic design, increased the stress stimulation of intervertebral, avoided stress to shelter from, favourable early rehabilitation.
3. The utility model increases the displacement and stress detection of the joint of the screw and the rod, and can intelligently judge whether the screw rod system has complications such as looseness, fracture, screw withdrawal and the like;
4. the utility model can automatically analyze and convert the data recorded by the stress sensor, the displacement sensor and the gravity sensor into the patient curve, so as to analyze the patient data such as the activity, the activity time, the horizontal time, the rehabilitation training exercise time and the like of the patient, and the data can be used for guiding the patient to do rehabilitation exercise better by the doctor;
5. the utility model discloses the design has the chemoreceptor, can acquire local circumstances such as material pieces such as nail stick system surface PH value, titanium alloy piece, PEEK piece to transmit APP to whether the doctor judges that there is material degradation, inefficacy.
