Description

Technical Field

Since the position and shape of the organ may change due to the movement of the human trunk or the physiological activities of the human body, the functional components such as the implanted sensors or stimulation electrodes installed in the organ are easy to fall off. For example, the traditional bladder pressure monitoring device buries the pressure sensor in the bladder wall mucosa. The mucosal tissue has limited thickness and is repellent. The bladder wall repeatedly contracts and relaxes during urine storage and urination. After the operation, the sensor is easily expelled by the mucosal tissue and caused to fall off. Summary of the invention

[0003] The present application provides an implantable covering device, which solves the problems of implantable control devices being easy to fall off, implantable control devices being inconvenient to install, traditional implantable control devices needing to be re-implanted due to battery exhaustion, thus causing new trauma to the user, and traditional implantable control devices taking up a large amount of space.

[0004] The technical solution adopted in this application is:

[0005] The implantable covering device of the present application is capable of covering an organ, and the implantable covering device includes a flexible baseband and a flexible circuit. The flexible baseband has a plurality of flexible branches extending therefrom, and each flexible branch has a connection end for surrounding connection, so that the flexible branch can form a structure surrounding the organ; the flexible circuit is arranged on the flexible baseband, and the flexible circuit includes a flexible strain sensing circuit, a flexible stimulation circuit and a flexible magnetic induction circuit. The flexible strain sensing circuit is arranged on the flexible branch to be distributed around the organ structure to obtain deformation information of the organ; the flexible stimulation circuit can send a stimulation signal to the organ according to the deformation information; the flexible magnetic induction circuit can be magnetically coupled with an external device to power other circuits in the flexible circuit.

[0006] The implantable covering device is provided with a flexible branch with a connecting end on the flexible baseband, so that the flexible branch can form a structure surrounding the organ, and multiple flexible branches can form multiple structures surrounding the organ, so that the flexible baseband can be covered on the organ, so that the flexible baseband can be fixed on the organ that needs to be monitored and stimulated, and the flexible baseband can be prevented from falling off the organ that needs to be monitored and stimulated.

[0010] In one embodiment of the present application, the connection end of each flexible branch can be connected to one side of the main flexible band to form a surrounding organ structure.

[0011] The implantable covering device can make the connection method of the flexible branches more flexible by connecting the connecting end of each flexible branch to one side of the main flexible belt to form a structure surrounding the organ, thereby reducing the difficulty of the operation. During the operation, the doctor can adjust the connection position of the flexible branch and the main flexible belt according to the actual situation of the user's organ, thereby making the operation more flexible.

[0049] In order to have a clearer understanding of the technical features, purposes and effects of the present application, the specific implementation methods of the present application are now described with reference to the accompanying drawings. The same reference numerals in the drawings represent components with the same structure or similar structures but the same functions.

[0050] In this document, “exemplary” means “serving as an example, instance or illustration”, and any diagram or implementation described in this document as “exemplary” should not be interpreted as a more preferred or more advantageous technical solution.

[0051] In order to simplify the drawings, only the parts related to the present application are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically drawn or marked.

[0052] Figure 1 A schematic structural diagram of an exemplary embodiment of an implantable covering device. Figure 2 A schematic three-dimensional diagram of an exemplary embodiment of an implantable covering device forming a surrounding organ structure. Figure 1 As shown, the implantable covering device includes a flexible base band ( Figure 1 Medium thick line outline structure) and flexible circuit ( Figure 1 (internal structure of medium and fine lines).

[0053] Among them, the flexible baseband ( Figure 1 The thick outline structure has multiple flexible branches extending out. Figure 1In the embodiment shown, the flexible base band has three pairs of symmetrically arranged flexible branches 11, two pairs of flexible branches 11 are respectively located on the left and right sides of the figure, and each flexible branch 11 has a connecting end 13 for surrounding connection, and the connecting ends 13 of each pair of flexible branches 11 can be connected, for example, by suturing, gluing, etc., so that the flexible branches 11 can be connected to form a surrounding organ structure 14 through surrounding connection. Please also refer to Figure 2 , Figure 1 The three pairs of flexible branches 11 in the Figure 2 The three surrounding organ structures 14 are used to wrap the implantable covering device around the organ, for example, see Figure 3 By surrounding the organ structure 14, the implantable covering device can be covered on the bladder. Of course, in other embodiments, the implantable covering device can also cover other organs, such as Figure 4 and Figure 5 As shown, the implantable coating device can cover the stomach and intestines.

[0054] In addition, since the flexible base band can achieve flexible deformation, the surrounding organ structure 14 can deform with the deformation of the organ during physiological activities, such as Figure 3 The bladder shown in the figure will change in volume before and after urination, and the surrounding organ structure 14 will change with the change in the volume of the bladder and always fit the organ without falling off.

[0055] Flexible Circuit( Figure 1 The internal structure of the middle and thin wires is arranged on the flexible baseband, and the flexible circuit includes a flexible strain sensing circuit 21, a flexible stimulation circuit 22 and a flexible magnetic induction circuit 23.

[0056] like Figure 1 As shown, the flexible strain sensing circuit 21 is disposed on the flexible branch 11 to be distributed around the organ structure 14. The surrounding organ structure 14 is shown in FIG. Figures 2 to 5 As mentioned above, the surrounding organ structure 14 will deform with the physiological activities of the organ, 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 obtained by the flexible strain sensing circuit 21, so that the organ can perform different actions. The flexible magnetic induction circuit 23 can be magnetically coupled with external equipment to power other circuits in the flexible circuit, that is, after the implantable covering device is implanted in the human body, magnetic induction coupling can be performed from the outside of the human body through external equipment with the flexible magnetic induction circuit 23 implanted in the human body, so that the flexible magnetic induction circuit 23 generates an induced current, and the induced current can be supplied to other circuits such as the flexible stimulation circuit 22 and the flexible strain sensing circuit 21 to realize power supply.

[0057] exist Figure 1In the embodiment shown, in addition to the flexible strain sensing circuit 21 being arranged on a pair of flexible branches 11, the flexible stimulation circuit 22 and the flexible magnetic induction circuit 23 are also arranged on a pair of flexible branches 11. Specifically, the flexible base band also has a main flexible band 12, and the three pairs of flexible branches 11 are extended from the side of the main flexible band 12. The two flexible branches 11 in each pair of flexible branches 11 are arranged opposite to each other with respect to the extension direction of the main flexible band 12. Figure 1 Among the three pairs of flexible branches 11, the top pair of flexible branches 11 with flexible magnetic induction circuits 23 are named power supply branches 111, the middle pair of flexible branches 11 with flexible strain sensing circuits 21 are named monitoring branches 112, and the bottom pair of flexible branches 11 with flexible stimulation circuits 22 are named stimulation branches 113, that is, the flexible stimulation circuits 22 and the flexible magnetic induction circuits 23 are respectively located in the flexible branches 11 at both ends of the main flexible belt 12.

[0058] In this embodiment, three pairs of flexible branches 11 can form three surrounding organ structures 14, which helps to make the implantable covering device fit the organ more firmly. For the stimulation branch 113, the stimulation position of the flexible stimulation circuit 22 and the organ can be kept more accurately. For the power supply branch 111, the flexible magnetic induction circuit 23 can follow the surrounding organ structure 14 to form a ring structure, which is more conducive to the magnetic induction coupling of the flexible magnetic induction circuit 23. And based on the cooperation of the above-mentioned flexible branches 11 and the main flexible belt 12, the arrangement of the flexible branches 11 on the flexible base belt can be made more orderly, which not only helps the flexible base belt to be attached, but also makes the force on the organ more uniform and reduces the discomfort. The above structure makes the flexible base belt more balanced as a whole and the attachment position more accurate, especially for the flexible strain sensing circuit 21 in the monitoring branch 112 and the flexible stimulation circuit 22 in the stimulation branch 113, a more accurate attachment position can ensure accurate monitoring results and stimulation control. Of course, according to different design requirements, the number and setting method of the flexible branches 11 can also be different, and examples will be given in detail later.

[0059] Taking the use of the above-mentioned implantable coating device on the bladder as an example, for patients with lower urinary tract dysfunction, they cannot feel the urge to urinate and cannot urinate autonomously. The implantable coating device can be positioned on the bladder through the surrounding organ structure 14 formed by the flexible base band, such as Figure 3As shown, the monitoring branch 112 can sense the change of bladder volume through the flexible strain sensing circuit 21 set thereon to determine the bladder state and the amount of urine inside, and then according to the above bladder state and the amount of urine inside obtained by the flexible strain sensing circuit 21, the flexible stimulation circuit 22 on the stimulation branch 113 is used to stimulate specific nerves on the bladder, so that the detrusor and other related muscle groups complete the corresponding action, so that the patient completes the urination action or inhibits the urination action. And as mentioned above, the flexible magnetic induction circuit 23 can be magnetically coupled with external equipment to power other circuits in the flexible circuit, realize internal power supply, will not limit the patient's freedom of movement and the environment in which he is located, and greatly improve the patient's quality of life.

[0060] In addition to the above-mentioned bladder, the implantable coating device can be applied to a variety of needs. The flexible nature of its flexible baseband makes it easy to carry flexible circuits and very convenient to change the implantable coating device from a two-dimensional structure to a three-dimensional structure, which is not only conducive to the implantation surgery, but also very convenient for the customized production of human organs. The material of the flexible baseband can be selected from PU, PDMS, Ecoflex and other materials. The entire molding process can be 3D printing, mold casting and whole material cutting.

[0061] The flexible circuit is arranged on the flexible baseband, which avoids the problem that the wires are easy to cause damage to the organs in the human body when they are routed in the human body. The flexible baseband is a strip structure, and the volume of the flexible baseband per unit length is small, and the contact area with the tissue around the organ is small, so that the implantable covering device has a moderate covering area on the organ, which will not compress the surrounding tissue, reduce discomfort, and prevent the flexible baseband from falling off. Each flexible branch 11 is arranged at intervals, and the flexible branch 11 surrounds the organ to form a surrounding organ structure 14 and deforms with the deformation of the organ. It can reduce the situation where other flexible branches 11 affect the deformation degree of the monitoring branch 112 due to the different deformation degrees of different positions of the organ, and avoid affecting the deformation information of the organ monitored by the flexible strain sensor in the flexible strain sensing circuit 21, thereby ensuring the measurement accuracy. The flexible circuit can change with the change of the flexible baseband, so that the measuring element in the flexible circuit can fit the organ, thereby ensuring the monitoring accuracy. The flexible stimulation electrode in the flexible stimulation circuit 22 is a flexible part, which prevents the deformation of the flexible stimulation electrode in the flexible stimulation circuit 22 from being out of sync with the deformation of the organ, thereby causing the flexible stimulation electrode to be unable to contact the nerve, and avoids the situation where the organ cannot complete the corresponding target action due to the inability of the stimulation electrode to stimulate a specific nerve normally, so that the organ cannot complete the target function. The technicians in the technical field of the present application can understand that the implantable coating device can be used not only on the bladder, but also on other organs, such as Figure 4 The stomach shown Figure 5The intestines and other organs shown to resolve or relieve conditions such as gastroparesis, gastroesophageal reflux disease, irritable bowel syndrome, etc. Figure 1 The flexible base band in the implantable covering device shown has flexible branches 11 arranged at intervals, and the structure of the covered organ formed is a mesh structure, so that the flexible branches 11 can be inserted between the blood vessels or other pipes connected to the organ, thereby playing a role in auxiliary fixation and preventing displacement. The implantable covering device is attached to the outer surface of the organ, which can effectively alleviate the situation of impurities deposited on the surface of the implantable covering device.

[0062] exist Figure 1 In the embodiment shown, the flexible branches on the flexible base band are arranged in pairs and symmetrically, but those skilled in the art of the present application can understand that the flexible branches 11 can also be asymmetrical or even unpaired, that is, Figure 1 The paired flexible branches 11 can be arranged asymmetrically, which will not be described in detail here. Figure 6 (The flexible circuit part is omitted in the figure), three flexible branches 11 can be extended only on the side of the main flexible belt 12, and the connecting end 13 of each flexible branch 11 can be connected to one side of the main flexible belt 12 to form Figure 3 The surrounding organ structure 14 is shown.

[0063] By enabling the connection end 13 of each flexible branch 11 to be connected to one side of the main flexible belt 12 to form a structure 14 surrounding the organ, the connection method of the flexible branch 11 to form a structure 14 surrounding the organ can be more flexible. During the operation, the doctor can adjust the connection position of the connection end 13 on the flexible branch 11 and the main flexible belt 12 according to the actual situation of the user's organ, thereby making the operation more flexible and reducing the difficulty of the operation. The flexible base belt can be more closely attached to the outer surface of the organ, so that the flexible strain sensing circuit 21 can obtain more accurate organ deformation information, thereby allowing the user to obtain better use results.

[0064] Those skilled in the art of the present application will understand that the number of flexible branches 11 in the implantable covering device is not limited to Figure 1 The three pairs shown or Figure 6 The three shown can also be other numbers, such as Figure 7 In the five pairs shown, the flexible circuits not only have flexible magnetic induction circuits 23, flexible strain sensing circuits 21, and flexible stimulation circuits 22, but may also have other circuits, which will be described in detail below.

[0065] Figure 7 The present invention is a schematic structural diagram of another exemplary embodiment of an implantable covering device.

[0066] like Figure 7 As shown, the flexible baseband ( Figure 7The structure with a middle thick outline has a main flexible belt 12 and five pairs of symmetrically arranged flexible branches 11, each pair of flexible branches 11 is located on the left and right sides of the figure, and the connecting ends 13 in each pair of flexible branches 11 can be connected by suturing, laminating, etc., so that the flexible branches 11 can form a surrounding organ structure 14 (see Figure 2 ), the more surrounding organ structures 14 are formed, the more stably the implantable covering device can be fixed on the organ, reducing the risk of sliding and displacement of the implantable covering device, thereby ensuring the monitoring accuracy and stimulation accuracy of the implantable covering device. For better description, from top to bottom in the figure, one pair of the five pairs of flexible branches 11 are named power supply branches 111, one pair are named temperature branches 114, one pair are named monitoring branches 112, one pair are named inductive branches 115, and one pair are named stimulation branches 113. Along the extension direction of the main flexible belt 12, the power supply branch 111 is arranged at one end of the main flexible belt 12, the stimulation branch 113 is arranged at the other end of the main flexible belt 12, the monitoring branch 112 is arranged in the middle of the main flexible belt 12, the temperature branch 114 is arranged between the power supply branch 111 and the monitoring branch 112, the inductive branch 115 is arranged between the monitoring branch 112 and the stimulation branch 113, the flexible strain sensing circuit 21 is arranged on the monitoring branch 112, the flexible stimulation circuit 22 is arranged on the stimulation branch 113, and the flexible magnetic induction circuit 23 is arranged on the power supply branch 111.

[0067] like Figure 7 As shown, the flexible circuit in the implantable covering device also includes a flexible temperature sensing circuit 24. The flexible temperature sensing circuit 24 is arranged on the temperature branch 114, so that it is distributed around the organ structure 14, so that the flexible temperature sensor in the flexible temperature sensing circuit 24 can perform a more accurate temperature monitoring of the organ, and the flexible temperature sensing circuit 24 is connected to the flexible magnetic induction circuit 23, so that the flexible magnetic induction circuit 23 can power the flexible temperature sensing circuit 24. The implantable covering device is provided with a flexible temperature sensing circuit 24, so that the flexible circuit can obtain the temperature information of the organ, thereby assisting in judging the condition of the organ, and comprehensively combining the information obtained by the flexible strain sensing circuit 21 and the flexible temperature sensing circuit 24 to determine whether the flexible stimulation circuit 22 stimulates the organ. For example, when the implantable covering device is arranged on the bladder, the flexible temperature sensing circuit 24 is arranged on the temperature branch 114, and the temperature branch 114 is arranged between the power supply branch 111 and the monitoring branch 112. Refer to Figure 3In the installation direction of the implantable covering device shown, when the temperature branch 114 forms a surrounding organ structure 14, the flexible temperature sensing circuit 24 can surround the bladder to monitor the bladder temperature. The temperature branch 114 is set near the relatively full place of the bladder abdomen to ensure that the overall temperature of the bladder can be accurately sensed, so as to cooperate with the deformation information of the bladder obtained by the flexible strain sensing circuit 21 to determine whether to stimulate the bladder.

[0068] like Figure 7 As shown, the flexible circuit in the implantable covering device can also include a flexible electromyographic sensing circuit 25. The flexible electromyographic sensing circuit 25 is arranged on the inductive branch 115, so as to be distributed around the organ structure 14. When the inductive branch 115 forms a surrounding organ structure 14, the flexible sensing electrodes in the flexible electromyographic sensing circuit 25 can monitor the electromyography on the organ more accurately. The flexible electromyographic sensing circuit 25 is connected to the flexible magnetic induction circuit 23, so that the flexible magnetic induction circuit 23 can power the flexible electromyographic sensing circuit 25. The implantable covering device can obtain the myoelectric information of the organ through the flexible myoelectric sensing circuit 25, and judge whether the flexible stimulation circuit 22 stimulates the organ by combining other information obtained by the flexible circuit. At the same time, the flexible myoelectric sensing circuit 25 can also sense the myoelectricity of the muscle group to judge whether the muscle group function is normal, and assist clinical diagnosis. After the flexible stimulation circuit 22 stimulates the muscle, the flexible myoelectric sensor in the flexible myoelectric sensing circuit 25 can monitor the bioelectric changes of the muscle group, so as to help judge whether the flexible stimulation circuit 22 has effectively stimulated the muscle group. For example, when the implantable covering device is set on the bladder, the flexible induction motor in the flexible myoelectric sensing circuit 25 can sense the myoelectricity of the detrusor muscle of the bladder, so as to reflect whether the bladder function is normal, thereby assisting the clinical diagnosis of bladder dysfunction.

[0069] Those skilled in the art of the present application can understand that the flexible temperature sensing circuit 24 and the flexible electromyography sensing circuit 25 can also be set in other flexible branches 11, not limited to the following. Figure 7 The flexible branch 11 can also carry flexible circuits with other functions to achieve different purposes.

[0070] Technicians in the technical field to which the present application belongs can understand that, in one embodiment of the implantable covering device, the flexible magnetic induction circuit 23 also includes an information output and receiving circuit, so as to be able to exchange information with external equipment, realize the transmission of monitoring information, and the input of external control information. The flexible magnetic induction circuit 23 in the implantable covering device can exchange information with external devices, so that the organ information obtained by the flexible circuit can be sent to the outside world through the flexible magnetic induction circuit 23, such as deformation information, temperature information, electromyographic information and other information of the organ, so as to assist the doctor in judging the user's organ condition, and the user can timely judge the actual situation of his own organ according to the information obtained by the flexible circuit, so as to seek medical treatment in time. The user can also determine whether to use the flexible stimulation electrode to stimulate the organ to complete the corresponding action according to the received organ information and the environment in which he is located. For example, when a user with lower urinary tract disorder is outdoors, it is inconvenient to urinate due to environmental factors, so the user can give the flexible stimulation circuit 22 a signal through the flexible magnetic induction circuit 23, so that the flexible stimulation circuit 22 stimulates specific nerves, thereby inhibiting urination. When the environment is suitable, the flexible stimulation circuit 22 is given a signal through the flexible magnetic induction circuit 23, so that the flexible stimulation circuit 22 stimulates specific nerves, so that the bladder completes the urination action. The flexible magnetic induction circuit 23 also includes an information output and receiving circuit so that the flexible magnetic induction circuit 23 can power other circuits in the flexible circuit while also communicating with the outside world. The material of the circuit in the flexible magnetic induction circuit 23 can be liquid metal, silver nanowire or other materials.

[0071] Since the flexible circuit is arranged on a flexible baseband, the flexible baseband will deform along with the deformation of the organ, and the flexible circuit will also deform accordingly. To prevent the circuit from breaking, the implantable covering device provides the following methods.

[0072] Fig. 9 A schematic structural diagram of an exemplary implementation of an electronic circuit in an implantable sheath device.

[0073] like Fig. 9 As shown, the electronic circuit 26 in the flexible circuit is arranged in a wavy routing form on the flexible baseband. The way in which the electronic circuit 26 in the flexible circuit is arranged in a wavy routing form on the flexible baseband allows the length of the electronic circuit 26 in the flexible circuit on the flexible baseband to have a margin when the flexible baseband changes with the shape of the organ, thereby improving the extensibility of the electronic circuit 26 in the flexible circuit, so that when the flexible baseband is stretched, the electronic circuit 26 in the flexible circuit can change with the length change of the flexible baseband, avoiding the electronic circuit 26 in the flexible circuit from breaking, and then avoiding the flexible circuit from being broken, thereby avoiding affecting the normal operation of the flexible circuit.

[0074] Those skilled in the art of the present application will understand that the arrangement of the flexible branches 11 in the implantable covering device on the flexible base band is not limited to the following: Figure 1 or Figure 7 The arrangement shown may also have other arrangements, which are described in detail below.

[0075] Figure 8 A schematic structural diagram of another exemplary embodiment of an implantable covering device.

[0076] like Figure 8 As shown in FIG. 1 (the flexible circuit part is omitted in the figure), the flexible baseband has six flexible branches 11 extending from the same node, each flexible branch 11 converges at the same node, and each flexible branch 11 can form a surrounding organ structure 14 (see FIG. 1 ) through its own connection end 13 (only one is marked in the figure). Figure 2 ), so that the flexible baseband can form a covering organ, so that the flexible baseband is fixed on the organ. The function and number of the circuits in the flexible circuit are selected according to the use requirements, and the position of the flexible circuit on the flexible baseband is selected according to the actual use requirements to adapt to the use requirements of different organs, which will not be repeated here, so that the implantable covering device can monitor and stimulate the organ.

[0077] It should be understood that although this specification is described according to various implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.

[0078] The series of detailed descriptions listed above are merely specific descriptions of feasible embodiments of the present application. They are not intended to limit the scope of protection of the present application. Any equivalent implementation scheme or changes that do not deviate from the technical spirit of the present application, such as combination, division or repetition of features, should be included in the scope of protection of the present application.
