Description
Technical Field
The utility model relates to the field of medical equipment, especially, relate to an intelligent interbody fusion cage.
Background
After the existing fusion cage is implanted, X-ray examination and CT examination need to be repeatedly carried out to assist in judging whether a patient achieves bone healing or not, the patient needs to repeatedly go to a hospital for carrying out examination for many times, and the problems of labor cost, time cost, economic cost and radiation hazard exist; and lack of record and feedback on the position of the fusion cage itself after implantation, stress conditions, and the patient's spinal motion, rehabilitation exercise time, rest time, recumbent time, etc.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an intelligent interbody fusion cage can be under the condition of not carrying out X-ray, CT inspection, and whether accurate judgement patient reaches the osseointegration, increases the rate of accuracy that the osseointegration judges to can carry out record and feedback to self position, stress condition etc. after the fusion cage is implanted.
In order to achieve the purpose, the utility model adopts the following technical proposal to realize:
the utility model discloses an intelligent interbody fusion cage, which comprises an outer sleeve and an inner sleeve; the stress sensor and the displacement sensor are arranged in a supporting part between the open end of the inner sleeve and the outer sleeve, and the gravity sensor is arranged on the inner wall of the outer sleeve or the inner sleeve.
Furthermore, the end surfaces of the outer sleeve and the inner sleeve are covered with an adhesion layer, and the adhesion layer is made of elastic alloy or degradable material.
Furthermore, an elastic component is arranged between the end surfaces of the outer sleeve and the inner sleeve and the adhesion layer.
Preferably, the supporting component is an elastic supporting component, and an elastic support is arranged between the inner wall of the outer sleeve and the outer wall of the inner sleeve.
Furthermore, a stress sensor is arranged on the elastic component.
Further, chemical sensors are arranged in the outer sleeve and the inner sleeve.
Further, displacement sensors are arranged on the end faces of the outer sleeve and the inner sleeve.
Preferably, the elastic component comprises a spring, a shrapnel or a crossed shrapnel.
Further, the utility model discloses still include intelligent terminal, stress sensor, displacement sensor, gravity sensor all with intelligent terminal wireless connection, intelligent terminal installs APP, APP is used for the data that analysis and processing stress sensor, displacement sensor, gravity sensor, chemical sensor acquireed.
Preferably, the intelligent terminal is a mobile phone.
The working principle of the utility model is as follows:
after the fusion cage is implanted, due to the existence of the gravity of a human body, the upper and lower 2 vertebral bodies can press the fusion cage, the elastic component can deform, the stress sensors at the gap between the outer sleeve and the inner sleeve and the stress sensors at the ends of the outer sleeve and the inner sleeve record the stress and transmit the stress to the connected intelligent terminal, and a doctor can observe the stress in an APP at the doctor end;
when the spine of the patient moves, for example, when the body changes posture, the elastic part and the elastic support deform again, the outer sleeve and the inner sleeve move slightly in the gap to generate displacement, and the stress also changes correspondingly; 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 the patient does not reach the intervertebral fusion (bone healing), the gravity of the patient is mainly transmitted through the intervertebral fusion device, the stress is mainly concentrated on the fusion device (one main function of the fusion device is the supporting function), and when the spine of the patient moves and changes the posture, the stress changes, the micromotion and the displacement are generated, and the gravity direction also changes. 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 cage is like a component in a hollow inside the concrete, and does not bear stress, produce micro-motion and displacement, but still has the gravity direction change. 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 be under the condition of not carrying out X-ray, CT inspection, whether accurate judgement patient reaches the osseointegration, reduce medical expenses, time cost, the human cost that X-ray, CT shot the cost, reduce the medical health expense of whole society.
2. The utility model can increase the accuracy of bone fusion judgment (the accuracy of fusion judgment of the existing X-ray and CT is lower, only about 50-70%).
3. The utility model can be used by pregnant women, pregnant woman and other radioactive hazard sensitive persons (pregnant women and pregnant woman need orthopedic surgery for worrying about radioactive hazard and diseases, which are always in embarrassing situation).
4. The elastic component can provide axial stress stimulation for the intelligent interbody fusion cage, is beneficial to bones and production, accelerates the bone fusion speed and improves the bone fusion quality.
5. The elastic support 7 can provide radial stress stimulation for the intelligent interbody fusion cage, so that radial stress can be generated in the horizontal position after adjustment. When standing upright, the stress is aggravated by the self-gravity, and the stress transmitted by the bone rises.
6. The chemoreceptor can acquire local conditions such as PH value, titanium alloy chip, PEEK chip and other material chips in the fusion cage, and transmits the local conditions to APP for the doctor judges whether the fusion cage has excessive wear, degradation and the like.
7. Through the data recorded by the stress sensors, the displacement sensors and the gravity sensors, the APP can be automatically analyzed and converted into a patient curve, so that the patient data such as the activity degree, the activity time, the lying time, the rehabilitation training exercise time and the like of the patient and the fusion device can be analyzed and obtained to judge whether the fusion device has complications such as displacement, dislocation, collapse and the like.
8. And displacement sensors are arranged on the end surfaces of the outer sleeve and the inner sleeve, so that whether the fusion cage has displacement or not can be judged, and whether the fusion cage has displacement looseness or not can be judged in an auxiliary manner.
