The flexible circuit (the internal structure of the thin line in fig. 1) is arranged on the flexible base band, and the flexible circuit comprises a flexible strain sensing circuit 21, a flexible stimulation circuit 22 and a flexible magnetic induction circuit 23.

As shown in fig. 1, the flexible strain sensing circuit 21 is disposed on the flexible branch 11 to be distributed around the surrounding organ structure 14, and as described above, the surrounding organ structure 14 deforms along with the physiological activity of the organ, as shown in fig. 2 to 5, and the flexible strain sensing circuit 21 can obtain the deformation information of the organ. The stimulation electrodes in the flexible stimulation circuit 22 can stimulate specific nerves on the organ according to the deformation information of the organ acquired by the flexible strain sensing circuit 21, so that the organ can complete different actions. The flexible magnetic induction circuit 23 can be magnetically and inductively coupled with external equipment to supply power to other circuits in the flexible circuit, that is, after the implanted covering device is implanted into the human body, the external equipment can be magnetically and inductively coupled with the flexible magnetic induction circuit 23 implanted into the human body from outside the human body, so that the flexible magnetic induction circuit 23 generates induction current, and the induction current can be supplied to other circuits such as the flexible stimulation circuit 22 and the flexible strain sensing circuit 21 to supply power.

In the embodiment shown in fig. 1, in addition to the flexible strain sensing circuit 21 being provided on the pair of flexible branches 11, the flexible stimulation circuit 22 and the flexible magnetic induction circuit 23 are also provided on the pair of flexible branches 11, respectively. Specifically, the flexible base strip further has a main flexible strip 12, the three pairs of flexible branches 11 extend from the side of the main flexible strip 12, and the two flexible branches 11 in each pair of flexible branches 11 are oppositely arranged with respect to the extending direction of the main flexible strip 12. For convenience of description, the uppermost pair of flexible branches 11 with the flexible magnetic induction circuits 23 in the three pairs of flexible branches 11 in fig. 1 is named as power supply branches 111, the middle pair of flexible branches 11 with the flexible strain sensing circuits 21 is named as monitoring branches 112, and the lower pair of flexible branches 11 with the flexible stimulation circuits 22 is named as stimulation branches 113, namely, the flexible stimulation circuits 22 and the flexible magnetic induction circuits 23 are respectively located at the flexible branches 11 at the two ends of the main flexible strip 12.

The structure makes the whole flexible base band more balanced, the attaching position is more accurate, and especially for the flexible strain sensing circuit 21 in the monitoring branch 112 and the flexible stimulation circuit 22 in the stimulation branch 113, the more accurate attaching position can ensure the accurate monitoring result and stimulation control. Of course, the number and arrangement of the flexible branches 11 may be different according to different design requirements, and will be described in detail by way of example later.

Taking an example of the use of the implantable covering device on the bladder, for a patient with lower urinary tract dysfunction, the implantable covering device cannot sense the desire for urination and can not urinate autonomously, the implantable covering device can be positioned on the bladder through the surrounding organ structure 14 formed by the flexible base band, as shown in fig. 3, and the monitoring branch 112 can sense the volume change of the bladder through the flexible strain sensing circuit 21 arranged thereon to judge the state of the bladder and the amount of internal urine, and then stimulate a specific nerve on the bladder by using the flexible stimulation circuit 22 on the stimulation branch 113 according to the state of the bladder and the amount of internal urine obtained by the flexible strain sensing circuit 21, so that relevant muscle groups such as detrusor muscle complete corresponding actions, thereby enabling the patient to complete urination actions or inhibit the urination actions. And as mentioned above, the flexible magnetic induction circuit 23 can be magnetically and inductively coupled with external equipment to supply power to other circuits in the flexible circuit, so as to realize internal power supply, without limiting the freedom of movement and the environment of the patient, thereby greatly improving the life quality of the patient.

Besides the bladder, the implanted coating device can be suitable for various requirements, the flexible characteristic of the flexible base band of the implanted coating device is convenient for bearing a flexible circuit, the implanted coating device is very convenient to change from a two-dimensional structure to a three-dimensional structure, the implanted coating device is not only beneficial to the implementation of an implantation operation, but also very convenient for the customized production of human organs.

Each flexible branch 11 interval sets up, and when flexible branch 11 encircled organ formation and encircled organ structure 14 and took place deformation along with the deformation of organ, can reduce because the difference of the different position deformation degree of organ leads to the condition emergence that other flexible branch 11 caused the influence to the deformation degree of monitoring branch 112, avoids influencing the deformation information of the organ of the flexible strain sensor monitoring in the flexible strain sensing circuit 21 to guarantee measurement accuracy. The flexible circuit can change along with the change of flexible baseband, thereby make the measuring element among the flexible circuit can laminate the organ, thereby guarantee the monitoring accuracy, flexible stimulation electrode among the flexible stimulation circuit 22 is the flexure, prevent that the deformation of flexible stimulation electrode among the flexible stimulation circuit 22 is asynchronous with organ deformation, thereby lead to the condition that flexible stimulation electrode and nerve can not contact to take place, avoid the unable normal amazing specific nerve of stimulation electrode to lead to the organ can not accomplish corresponding purpose action, make the condition that the organ can not accomplish the purpose function take place. Those skilled in the art will appreciate that the implantable covering device can be used not only on the bladder, but also on other organs, such as the stomach shown in fig. 4, the intestine shown in fig. 5, etc., to solve or alleviate gastroparesis, gastroesophageal reflux disease, irritable bowel syndrome, etc. The flexible base band in the implantable covering device shown in fig. 1 has flexible branches 11 arranged at intervals, and the structure of the formed covering organ is a net structure, so that the flexible branches 11 can be inserted between blood vessels or other pipelines connected with the organ, thereby playing the roles of auxiliary fixation and displacement prevention. The mode that the implanted coating device is pasted on the outer surface of the organ can effectively relieve the condition that impurities are deposited on the surface of the implanted coating device.
