Description
Technical Field
The application relates to the technical field of implantable medical devices, in particular to a receiving coil fixing device of a wireless energy supply device for an implantable medical device.
Background
The implanted medical device is an electronic device embedded in animals or human bodies and has important medical effect. Currently, implantable medical devices are widely applied and various in variety, and products existing in the market mainly include artificial hearts (ventricular assist devices), artificial cochlea, insulin pumps, brain nerve stimulators, monitoring systems and the like. As medical devices implanted in the body, lithium primary batteries with high energy density are used for power supply in the past, but the service life is not ideal. In recent years, with the development of wireless technology and rechargeable battery technology, development of wirelessly chargeable implantable medical devices having a longer service life has become a mainstream trend. Also, for convenience of daily charging of the patient, reduction of risk of insufficient electric power for life safety of the patient, and support of more and more power consuming functions, it is desirable that the charging efficiency is high enough for quick charging.
Because the implantable medical device is implanted into the patient and isolated from the external charging device by tissues such as skin, a wireless charging mode through skin tissues is needed. The charging mode is generally based on the electromagnetic coupling principle, energy is emitted in the form of electromagnetic waves by a transmitting coil positioned outside the body, is received by a receiving coil implanted in the body after penetrating skin tissues and is then transmitted to an implanted medical instrument, so that the requirements on the position alignment and the energy transmission distance of the transmitting coil and the receiving coil are high. To maximize the charging efficiency, the transmit and receive coils must be aligned accurately and stably while the two coils are as close as possible, so it is desirable that the receive coils be positioned as close to the skin as possible within the body. If the coil is not fixed firmly enough, dislocation appears in the alignment during charging, can lead to the charging efficiency to drop, influences medical instrument's normal use, brings the risk for the patient. For this purpose, various fastening devices are known in the prior art, such as fastening straps for attaching the transmitter coil of the artificial heart energy supply device to the corresponding position in front of the chest. An automatic alignment fixture is also known in which the receiver coil is fixed in the body together with the implanted part of the medical device, and a position sensing coil is provided in the body together with the transmitter coil, and by monitoring the magnetic field generated by the receiver coil, the current position and deflection angle of the receiver coil can be estimated, and based thereon, the position and deflection angle of the transmitter coil can be adjusted.
However, most of the prior art, which starts from the fixation of the transmitting coil outside the body, has certain drawbacks. First, none or very little of these techniques take into account the fixation of the receiving coil implanted in the body. In practical use, in order to alleviate the burden and pain of the patient, the design and use time of the implantable medical device which is implanted in the body through surgery is generally long, which may be as long as tens of years, while the receiving coil which is usually fixed with the implanted portion of the implantable medical device is far away from the skin, and after long-term implantation, offset, especially torsion, may occur, which causes a change in position thereof, affecting the alignment of the transmitting coil in the body. Even in the above-described self-aligning fixing device, the receiving coil is fixed together with the implanted portion of the medical instrument in the body, which restricts the optional positions of the receiving coil, and cannot be fixed to a position closest to the skin, affecting the charging efficiency. The position of some implantable medical devices is not completely fixed, e.g., the position of an artificial heart may change continuously under the influence of a heartbeat. Although the position sensing coil can be used for ensuring accurate alignment of the transmitting coil and the receiving coil, the distance between the two coils can be increased after the receiving coil is implanted in the body for a long time, and the energy transmission efficiency is affected. In addition, because implantable medical devices are generally expensive, the patient is burdened, and the manufacturing and cost issues of prior art fixation devices are not negligible.
Disclosure of Invention
The application aims at solving the problems existing in the prior art, and the inventor innovatively starts from the aspect of fixing the receiving coil implanted in the body, designs a brand-new fixing device for the receiving coil, has a simple structure, is easy to manufacture and low in cost, can greatly shorten the energy transmission distance, and solves the problem that the receiving coil is easy to shift.
To this end, the application provides a receiving coil fixing device for a wireless power supply device of an implantable medical device, comprising a housing for accommodating the receiving coil and a flexible cloth covering at least a part of an outer surface of the housing, wherein the housing is made of an insulating material safe for a human or animal body, the flexible cloth being fixed with at least a part of the outer surface of the housing covered thereby and being a biocompatible fleece capable of growing together with tissue of the human or animal body.
By means of the fixation of the flexible cloth together with the body tissue, the receiving coil fixed by the receiving coil fixing device according to the application is no longer fixed with the rest of the implanted part of the implantable medical device, but can be firmly fixed in a subcutaneous position closest to the body surface skin and is not loosened due to long-time implantation. Therefore, the positioning accuracy and stability of the transmitting coil and the receiving coil outside the body are greatly facilitated, the problem that the receiving coil is easy to shift is solved, the transmission distance of energy between the transmitting coil and the receiving coil is shortened to the greatest extent, and therefore the charging efficiency is greatly improved. The receiving coil fixing device is also beneficial to the design and manufacture of other elements such as the transmitting coil fixing device. Furthermore, since the receiving coil is no longer fixed with the rest of the implanted portion of the implantable medical device for implantation onto the body organ or site to be treated or monitored, the volume of the implanted portion and the burden on the body implantation site to be treated or monitored can be reduced. In addition, for various implantable medical devices, a special design is required to assemble and fix the receiving coil, while the receiving coil fixing device according to the application has universality, and all the components can be manufactured independently, and only the receiving coil is required to be assembled with the receiving coil after matching the shape and the size of the receiving coil. The housing and flexible cloth may be made of conventional materials known in the art and are therefore easy to manufacture.
The receiving coil fixture of the wireless powering device for implantable medical devices according to the present application may also include one or more of the following optional features, alone or in combination.
Preferably, the flexible cloth is fixed to at least a part of the outer surface of the housing covered by the flexible cloth by means of stitching or gluing. Such a fixation not only ensures that the flexible cloth does not displace with the housing in any way, so that the whole fixation device can be firmly fixed to the desired part of the body by the flexible cloth growing together with the body tissue, but also is easy to handle and safe for the human or animal body.
Preferably, the flexible cloth has a suture portion for suturing with the tissue of the human or animal body, except for a portion fixed to the housing. In this way, when the receiver coil fixture housing the receiver coil is surgically implanted, the receiver coil fixture can be positioned to the desired location of the body by conventional surgical suturing means, such as using a detachable absorbable suture, by suturing the suture portion of the flexible cloth to the body tissue.
Preferably, the housing is provided such that, of the overall three-dimensional dimensions of the housing, a dimension in a direction parallel to a transmission direction of the electromagnetic wave received when the receiving coil is accommodated in the housing is a minimum dimension, and the smaller the dimension is, the better. The minimum dimension is understood to be the thickness of the housing. The fact that the thickness direction of the housing is parallel to the transmission direction of the electromagnetic waves means that the distance over which the electromagnetic waves are received by the receiving coil therein after reaching the housing does not exceed the thickness of the housing, and thus such an arrangement is advantageous in shortening the transmission distance of the electromagnetic waves, i.e. energy, relative to other arrangements. And because the shorter the transmission distance is, the better the thickness of the case is designed to be smaller, so as to shorten the energy transmission distance as much as possible, maximizing the charging efficiency.
Preferably, the housing is a removable housing. Thereby, versatility and ease of manufacturing of the receiving coil fixing device are further improved.
Preferably, the housing is made of a silicone or thermoplastic polyurethane elastomer (TPU) material. The silica gel and TPU materials are friendly to implanted human bodies and animals, have no toxicity, harm and corrosiveness, and have good insulating property and stable chemical property. In addition, the material has certain softness and good hand feeling, so the material is easy to implant and is beneficial to improving the comfort level of patients.
Preferably, the housing has a protrusion on an outer surface. The protrusions may increase the contact area of the surface of the housing with the tissue of the human or animal body, thus facilitating fixation and preventing displacement.
Preferably, the housing is integrally molded.
Preferably, the housing is divided into an upper case and a lower case. The upper case and the lower case may be fixed by means of adhesive.
Preferably, the flexible cloth covers the outer surface of the upper and/or lower shells of the housing.
In general, as described above, a flexible cloth covering a portion of the outer surface of the housing may be sufficient to secure the assembly of the securing device and the receiving coil to the body tissue. In some cases, however, the outer surface of the housing is covered over a large area or even entirely with a flexible cloth to grow with the body tissue at all locations where it contacts the body tissue, which may provide a safer fixation and a faster fixation.
According to one embodiment of the present application, there is also provided an assembly of a receiving coil and a receiving coil fixture for a wireless powering device of an implantable medical device, wherein the receiving coil fixture is a receiving coil fixture as described above, the receiving coil being accommodated in the receiving coil fixture.

This way it is also ensured that the receiving coil is not displaced in the housing, so that the alignment of the transmitting coil with the receiving coil is more accurate and stable.
Preferably, the receiving coil and the housing are fixed by gluing. In the case where the receiving coil and the housing are fixed by means of inlaying or upper and lower housing clamping as described above, the receiving coil and the housing are further fixed, preferably by means of gluing.

Fig. 1 and 2 schematically show a receiving coil fixture 1 of a wireless power supply device for an implantable medical device according to an embodiment of the present application in perspective view and in exploded view, respectively. As shown in fig. 1, a receiving coil 2 is mounted in a receiving coil fixing device 1. The receiving coil 2 is shown as a whole in a circular shape, so that the receiving coil holder 1 adapted thereto is in a round cake shape as a whole. It is to be noted that the smaller the thickness of the housing 12 (see fig. 2) of the receiving coil fixing device 1 in the electromagnetic wave transmission direction is, the better, in order to facilitate the charging efficiency. For example, in one application of the artificial heart, such a pie-shaped casing having a diameter of about 4cm to 8cm and an overall thickness of less than 13mm achieves good results. It will be appreciated that the shape of the receiving coil 2 and the receiving coil holder 1 is not limited thereto, but depends on the specifications of the wireless powering device of the applied implantable medical device and the constraints of the body implantation site. It will also be appreciated that any material to be used in contact with human or animal body tissue, whether silica gel or biocompatible fleece, or glue to secure them, etc. used as a device to be used with the human or animal body, needs to meet the corresponding standards for use with the human or animal body in order to ensure safety to the human or animal body and thus can be implanted in the body for a long period of time without causing additional risks. The receiving coil 2 adopts a wireless charging technology which is widely used at present, and the conventional technology which is well known per se is not described herein, so the following description focuses on the receiving coil fixing device 1.
Referring to fig. 2, the receiving coil fixing device 1 mainly includes a flexible cloth 11 and a housing 12. The flexible cloth 11 covers and is fixed to at least a portion of the outer surface of the housing 12, for example, by means of a seam or an adhesive, so that the flexible cloth 11 is firmly bonded to the housing 12 without reference numerals in fig. 1. The flexible cloth 11 is a biocompatible fleece that can grow together with the tissue of the human or animal body, so that the whole of the receiving coil fixing device 1 can be firmly fixed with the tissue of the human or animal body by means of the cloth. Such cloth is often used in fasteners requiring medical devices to be implanted in the body, such as ventricular sewing rings of artificial hearts, for example, double-sided fleece of implant-grade polyester fibers with high biocompatibility, and thus is not described in detail herein as a matter of routine in the art. The biosolids provided by the flexible cloth 11 are very strong and have the advantage of not loosening even after prolonged implantation. The flexible cloth 11 may cover and be fixed to any part of the outer surface of the housing 12 as long as the combination obtained by growing the flexible cloth 11 together with the body tissue is sufficient to fix the assembly of the receiving coil fixing device 1 and the receiving coil 2. For the purpose of maximizing the charging efficiency, for example, for the receiving coil fixing device 1 in the shape of a pancake, it may be provided that the flexible cloth 11 covers and is fixed to at least a part of the circular outer surface of the housing 12, and may be arranged such that the thickness direction of the pancake is substantially parallel to the transmission direction of energy when implanted in the body, i.e., such that the annular surface formed by the windings on the receiving coil 2 is substantially parallel to the skin surface. Ideally, the flexible cloth 11 covers the entire outer surface of the housing 12, so that the binding can be achieved at all positions where the flexible cloth 11 is in contact with the body tissue, on the one hand, making the selection of the body part and the angle of placement more flexible when the receiver coil fixture 1 is surgically implanted, and on the other hand enabling the receiver coil fixture 1 to be fastened to the body tissue as early as possible. It will be appreciated that other known fastening means, both firm and safe to the human or animal body, may be used between the flexible cloth 11 and the outer surface of the housing 12, in addition to the above-mentioned stitching and gluing means.
Although not shown in the drawings, according to a preferred embodiment of the present application, the flexible cloth 11 of the receiving coil fixing device 1 has a suture portion for suturing with the tissues of the human or animal body in addition to the portion fixed to the housing 12. In this way, the receiver coil fixture 1 can be positioned to the desired location of the body by conventional surgical suturing means, such as using a detachable absorbable suture, to suture the sutured portion of the flexible cloth 11 to the body tissue at the time of surgical implantation. The size and shape of the suture may be set according to the particular application and the needs of the surgical suture. For example, in the case where the flexible cloth 11 is fixed to the outer surface of the housing 12 by means of gluing, a round of cloth edge may be left as a sewn portion at the periphery of the portion where the flexible cloth 11 is stuck to the housing 12. In some cases it is also possible that the stitching is realized as a strip of cloth extending over the surgical site around the part of the flexible cloth 11 fixed to the housing 12, such as teeth on a gear wheel.
With continued reference to the examples of fig. 1 and 2, the housing 12, which is made of an insulating material safe to the human or animal body, is capable of protecting the receiving coil 2 mounted therein, and in particular, of dissipating heat therefrom, so that the receiving coil 2 does not overheat to scald tissues or organs of the human or animal body. In addition to being stable and durable in nature and capable of long-term implantation, the material selection of the housing 12 preferably allows for a soft, hand-friendly implant material, such as a polymeric material such as silicone or TPU, for ease of implantation and for greater comfort to the human or animal body. The housing 12 may be a detachable housing, which is highly versatile, facilitates mass production, and allows the receiving coil 2 mounted therein to be replaced as necessary. For example, the housing 12 may be integrally molded, and the receiving coil 2 may be embedded in the housing 12 to immobilize the receiving coil 2. Although not shown in the drawings, the outer surface of the housing 12 may have a suitable shape such as a protrusion or the like thereon for increasing the contact area of the surface of the housing 12 with the tissue of the human or animal body, thus facilitating fixation and preventing displacement. The outer surface of the housing 12 covered with the flexible cloth 11 may also have the above-mentioned protrusions.
Referring to fig. 2, the housing 12 may be divided into an upper case 121 and a lower case 122. While the flexible cloth 11 substantially matches the outer shape of the upper case 121 and covers the outer surface thereof in this example, it may cover the outer surface of the lower case 122 or the outer surfaces of the upper case 121 and the lower case 122. It should be understood that the designations of "upper shell" and "lower shell" used herein are merely for convenience of placement with reference to the drawings to distinguish the two half shells, and do not limit their actual placement in the up-down direction, and are therefore also named "first half shell" and "second half shell". In this way, the receiving coil 2 can be clamped by the upper case 121 and the lower case 122, ensuring that there is no displacement when the receiving coil 2 is mounted in the housing 12. The upper and lower cases 121 and 122 may be fixed by means of gluing, since the gluing is relatively strong, but other known fixing means which are both strong and safe to the human or animal body are also possible.
According to a preferred embodiment of the application, the receiving coil 2 and the receiving coil holder 1 can be fixed by means of gluing. Alternatively, in the case where the receiving coil 2 is fixed in the receiving coil fixing device 1 by embedding or by clamping the upper and lower cases as described above, the receiving coil 2 may be further fixed with the receiving coil fixing device 1 by gluing to further ensure that the receiving coil 2 is not displaced in the receiving coil fixing device 1.
The receiving coil fixing device for the wireless power supply device of the implantable medical device according to the present application may not have the receiving coil installed at the time of shipment, or may have been assembled with the receiving coil. When the medical device is implanted, only one operation is needed, the implanted part of the medical device is implanted to a body part to be treated or monitored, the assembled receiving coil and the assembly of the receiving coil fixing device are subcutaneously implanted near the body surface, and the receiving coil and the medical device are electrically connected in the body. The direction and position of implantation of the receiving coil are considered in combination with reference to the patient's body and the transmitting coil outside the body. In the case of an artificial heart, for example, the implantation site of the receiving coil is advantageously located at a subcutaneous location of the chest corresponding to the heart, the implantation direction advantageously being such that the smallest dimension direction, i.e. the thickness direction, of the overall three-dimensional dimensions of the housing of the receiving coil holder is parallel to the transmission direction of the electromagnetic waves. Therefore, the electric connection between the receiving coil and the artificial heart implanted into the heart is facilitated, the external transmitting coil and the receiving coil are aligned by fixing auxiliary devices such as braces and the like, the energy transmission distance is short, and the charging efficiency is high.
The accompanying drawings and the foregoing description describe non-limiting specific embodiments of the present application. Some conventional aspects have been simplified or omitted in order to teach the inventive principles. It should be understood by those skilled in the art that any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the present application. Those skilled in the art will appreciate that the above features can be combined in various ways to form multiple variations of the application without conflict. For example, certain features of the present application have been described above as applied to an artificial heart, but the receiver coil securing apparatus of the present application is not limited to application to artificial hearts, but may be applied to various implantable medical devices. In addition, the above description of the present application has been given by taking the application of the present application to the human body as an example, but the present application is not limited to the application to the human body, and other animals may be used. For example, the above description of the application has been given with respect to a charging example, but the application is not limited to use for charging, but also includes direct powering of implantable medical devices in the body. Thus, the present application is not limited to the specific embodiments described above, but only by the claims and their equivalents.
