Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an implantable coil assembly. Background Technology

[0002] In recent years, with the continuous development of my country's medical level, the continuous increase in people's medical and health needs, and the standardized guidance of national policies, the market size of implantable medical devices has been growing. Implantable medical devices such as pacemakers, brain nerve stimulators, and artificial hearts can greatly improve patients' symptoms and quality of life, and are of great significance to actual clinical treatment.

[0003] Correspondingly, the continuous and stable operation of implantable medical devices is one of their important performance indicators, and wireless power transmission technology provides a solution for the long-term power supply of such devices, avoiding the huge risks and economic burdens of patients having to face a second surgery when the battery power is exhausted.

[0004] Generally, the application of existing wireless power transfer technology in implantable medical devices usually involves the cooperation of a component implanted in the human body and a component located outside the human body. Specifically, a coil implanted inside the human body is responsible for receiving radio electromagnetic waves, while a coil located outside the human body is responsible for emitting radio electromagnetic waves. In this way, the coil located outside the human body continuously supplies electrical energy to the coil located inside the human body, so that the coil located inside the human body can deliver electrical energy to devices such as pacemakers implanted in the human body, thereby ensuring the continuous and stable operation of these implantable medical devices.

[0005] However, although the above-mentioned component arrangement can meet the current application requirements of implantable medical devices, in actual operation, due to the lack of reliable relative fixation and stable limiting between the two coils located inside and outside the human body, there is a possibility of coil displacement after the components are installed. Once coil displacement occurs, it will directly cause a change in the electromagnetic wave transmission frequency between the two coils, resulting in a significant increase in coil heat generation, thereby affecting the working performance of the coils and causing a decrease in the power transmission efficiency between the two coils. In severe cases, it may even cause fluctuations or interruptions in the power supply of the corresponding implantable medical device, causing inconvenience to the daily life of patients with implanted medical devices such as pacemakers, and even endangering the life and health of patients.

[0006] In view of this, how to ensure the stable and reliable installation of the implantable coil assembly, and to make the alignment between the two induction coils more precise, and the corresponding power transmission more stable and efficient, is an important technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0007] The purpose of this invention is to provide an implantable coil assembly that is stable and reliable in installation, enabling more precise alignment between the two coil modules and resulting in smoother and more efficient power transmission.

[0008] To solve the above-mentioned technical problems, this utility model provides an implantable coil assembly, including a transmitting coil module located outside the human body and capable of emitting electromagnetic waves, and a receiving coil module capable of being implanted into the human body and receiving electromagnetic waves, wherein the bottom surface of the transmitting coil module is aligned and adapted with the top surface of the receiving coil module.

[0009] The outer periphery of the receiving coil module is provided with a reference connector, and the outer periphery of the transmitting coil module is provided with a positioning connector. The reference connector and the positioning connector are aligned and fitted one-to-one and snapped together.

[0010] Preferably, the receiving coil module includes a receiving substrate and a receiving coil body disposed on the top surface of the receiving substrate. The reference connector protrudes radially on the outer peripheral surface of the receiving substrate. The top of the reference connector is provided with an alignment boss, and the top end of the alignment boss protrudes from the top end of the receiving coil body and the top end of the receiving substrate.

[0011] The transmitting coil module includes a transmitting substrate and a transmitting coil body disposed on the bottom surface of the transmitting substrate. The positioning connector protrudes radially on the outer peripheral surface of the transmitting substrate. The bottom of the positioning connector is recessed and provided with a positioning slot that can be aligned, inserted and engaged with the positioning boss. The positioning boss and the positioning slot are detachably adapted to each other.

[0012] Preferably, a receiving guard plate is provided protruding from the outer edge of the top surface of the receiving substrate. The receiving guard plate extends circumferentially around the receiving substrate and is connected end to end to form a receiving cavity on the top of the receiving substrate that can accommodate the receiving coil body. The top of the alignment boss protrudes from the top of the receiving guard plate.

[0013] Preferably, a transmitting guard plate is provided protruding from the outer edge of the bottom surface of the transmitting substrate. The transmitting guard plate extends circumferentially around the transmitting substrate and is connected end to end to form a transmitting cavity at the bottom of the transmitting substrate that can accommodate the transmitting coil body.

[0014] Preferably, the transmitting coil body is bonded and fixed inside the transmitting wire cavity.

[0015] Preferably, the transmitting coil body is coiled around the axis of the transmitting substrate, and adjacent coiled cables are insulated from each other by potting.

[0016] Preferably, the receiving coil body is bonded and fixed inside the receiving wire cavity.

[0017] Preferably, the receiving coil body is coiled around the axis of the receiving substrate, and adjacent coiled cables are insulated from each other by potting.

[0018] Preferably, there are at least three reference connectors, and each reference connector is evenly distributed at equal intervals along the circumference of the receiving coil module;

[0019] There are at least three positioning connectors, and each positioning connector is evenly distributed at equal intervals along the circumference of the transmitting coil module.

[0020] Preferably, the sidewall and bottomwall of the reference connector are recessed with reference grooves that can accommodate surgical sutures, and the sidewall and topwall of the positioning connector are recessed with positioning grooves that can accommodate surgical sutures. The end opening of the reference groove is aligned and connected with the end opening of the positioning groove.

[0021] Compared to the aforementioned background technology, the implantable coil assembly provided by this utility model, during operation and use, involves implanting the receiving coil module into the patient's body. The receiving coil module is located beneath the patient's skin tissue. At this point, the transmitting coil module can be correspondingly fixed to the patient's skin surface, ensuring the positions of the transmitting and receiving coil modules align. Simultaneously, the positioning connector and the reference connector are aligned and snapped together through the patient's skin tissue, thereby achieving accurate alignment and reliable connection between the transmitting and receiving coil modules. Afterwards, surgical sutures can be used to reliably suture and fix the current fitting structure of the receiving and transmitting coil modules. The specific suture location can be selected at the snap-fit ​​assembly of the reference and positioning connectors; that is, the surgical suture is wrapped around the snap-fit ​​assembly structure of the reference and positioning connectors and sutured in place. This method utilizes surgical sutures to further securely fix the reference connector and the positioning connector, making their alignment and assembly structure more robust and reliable. This, in turn, ensures a more stable and precise alignment between the transmitting coil module and the receiving coil module, guaranteeing more sensitive and efficient electromagnetic wave transmission and induction between them. It avoids coil loosening and misalignment, as well as resulting electromagnetic wave frequency abnormalities and abnormal coil overheating. Ultimately, this effectively ensures a stable power supply and smooth operation for implantable medical devices such as pacemakers, brain stimulators, and artificial hearts compatible with the implantable coil assembly, thus effectively guaranteeing the patient's health and the smooth progress of related medical activities.

A reference connector protrudes radially from the outer peripheral surface of the receiving substrate, and a positioning boss protrudes from the top of the reference connector. The top of the positioning boss protrudes from the top of the receiving coil body and the top of the receiving substrate. The transmitting coil module includes a transmitting substrate and a transmitting coil body disposed on the bottom surface of the transmitting substrate. A positioning connector protrudes radially from the outer peripheral surface of the transmitting substrate, and a positioning slot is recessed at the bottom of the positioning connector to align and engage with the positioning boss. The positioning boss and the positioning slot are detachably adapted to each other. This concave-convex engagement structure formed by the alignment boss and the positioning slot has high alignment accuracy and a robust and reliable assembly structure, further ensuring the alignment accuracy and assembly stability of the transmitting coil module and the receiving coil module. In addition, the outward protrusion of the alignment boss can moderately lift the skin tissue at the location of the alignment boss, so that medical staff can more accurately and quickly find the position of the alignment boss, which facilitates the installation position calibration of the corresponding alignment slot and rapid alignment assembly, thereby further improving the alignment installation efficiency of the two coil modules of the implantable coil assembly and making its component assembly process simpler and smoother.

[0027] 12- Transmitting coil body. Detailed Implementation

[0028] The core of this invention is to provide an implantable coil assembly. This implantable coil assembly is stable and reliable in installation, enabling more precise alignment between the two coil modules and resulting in more stable and efficient power transmission.

[0029] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] It should be noted in advance that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing" in this utility model should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] Furthermore, in this invention, unless otherwise explicitly specified and limited, the first feature being "on" or "below" the second feature may include direct contact between the first and second features, or contact between the first and second features not being in direct contact but through another feature between them.

[0032] In addition, the terms "above," "over," and "on top" for the first feature and the second feature include the first feature being directly above or diagonally above the second feature, or simply indicating that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "under," and "beneath" for the first feature and the second feature include the first feature being directly below or diagonally below the second feature, or simply indicating that the first feature is at a lower horizontal level than the second feature. The terms "above," "below," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0033] In specific implementation methods, such as Figure 1 As shown, the implantable coil assembly provided by this utility model includes a transmitting coil module located outside the human body and capable of emitting electromagnetic waves, and a receiving coil module 11 capable of being implanted into the human body and receiving electromagnetic waves. The bottom surface of the transmitting coil module and the top surface of the receiving coil module 11 are aligned and adapted.

[0034] The outer periphery of the receiving coil module 11 is provided with a reference connector 111, and the outer periphery of the transmitting coil module is provided with a positioning connector. The reference connector 111 and the positioning connector are aligned and fitted one-to-one and snapped together.

[0035] Thus, in the specific operation and use of the implantable coil assembly, after the receiving coil module 11 is implanted into the patient's body, the receiving coil module 11 is located under the patient's skin tissue. At this time, the transmitting coil module can be fixed to the patient's skin surface, and the positions of the transmitting coil module and the receiving coil module 11 are aligned; at the same time, the positioning connector and the reference connector 111 are aligned and snapped together through the patient's skin tissue, thereby achieving accurate alignment and reliable connection between the transmitting coil module and the receiving coil module 11.

[0036] Subsequently, surgical sutures can be used to reliably suture and fix the current adaptation structure of the receiving coil module 11 and the transmitting coil module. The specific suture location can be the snap-fit ​​assembly of the reference connector 111 and the positioning connector; that is, the surgical suture is wrapped around the snap-fit ​​assembly structure of the reference connector 111 and the positioning connector and sutured in place. In this way, the reference connector 111 and the positioning connector are further reliably fixed using surgical sutures, making their alignment and adaptation assembly structure more robust and reliable. This results in a more stable and precise alignment and installation structure between the transmitting coil module and the receiving coil module 11, ensuring more sensitive and efficient electromagnetic wave transmission and induction between them. It avoids coil loosening and misalignment, as well as the resulting abnormal electromagnetic wave frequency and abnormal coil overheating. This effectively ensures a stable power supply and smooth operation of implantable medical devices such as pacemakers, brain stimulators, and artificial hearts adapted to the implantable coil assembly, effectively guaranteeing the patient's health and the smooth progress of related medical activities.

[0037] It is easy to understand that after the implantable coil assembly is fully assembled at the corresponding part of the patient's body, the skin at that corresponding part of the patient's body is located between the receiving coil module 11 and the transmitting coil module. The skin at this point may be moderately clamped and squeezed, but the specific skin condition should be flexibly adjusted by medical staff based on actual clinical conditions and working environment. In principle, the reliability of the assembly and arrangement of the implantable coil assembly should be ensured, and adverse effects on the patient's subsequent medical treatment and rehabilitation process should be avoided.

[0038] Furthermore, it should be noted that in actual operation, after the receiving coil module 11 is implanted into the patient's body, surgical sutures can be used to first suture and fix the receiving coil module 11 under the skin tissue at the corresponding location on the patient's body, so as to form a pre-position of the receiving coil module 11. Then, based on this structural reference, the corresponding transmitting coil module is aligned and installed, and subsequent suturing and fixation are carried out. This further optimizes the component assembly effect of the implantable coil assembly and further optimizes the corresponding component alignment and installation accuracy, making the overall installation and arrangement of the implantable coil assembly smoother and more convenient.

[0039] Specifically, the receiving coil module 11 includes a receiving substrate 112 and a receiving coil body 113 disposed on the top surface of the receiving substrate 112. A reference connector 111 protrudes radially from the outer peripheral surface of the receiving substrate 112. A positioning boss 114 protrudes from the top of the reference connector 111, and the top of the positioning boss 114 protrudes from the top of the receiving coil body 113 and the top of the receiving substrate 112. The transmitting coil module includes a transmitting substrate and a transmitting coil body 12 disposed on the bottom surface of the transmitting substrate. A positioning connector protrudes radially from the outer peripheral surface of the transmitting substrate. A positioning slot is recessed at the bottom of the positioning connector, which can be aligned, inserted, and engaged with the positioning boss 114. The positioning boss 114 and the positioning slot are detachably adapted to each other.

[0040] This type of interlocking structure, formed by the alignment boss 114 fitting into the alignment slot, boasts high alignment accuracy and a robust and reliable assembly structure. This further ensures the alignment accuracy and assembly stability of the transmitting coil module and the receiving coil module 11. Furthermore, the outward-protruding structure of the alignment boss 114 can moderately lift the skin tissue at its location, allowing medical personnel to more accurately and quickly locate the boss 114. This facilitates the calibration of the corresponding alignment slot's installation position and rapid alignment assembly, thereby further improving the alignment and installation efficiency of the two coil modules in the implantable coil assembly and making the component assembly process simpler and smoother.

[0041] It should be pointed out that, as Figure 1 The document only provides the complete component structure of the receiving coil module 11 and the aligned transmitting coil body 12 structure to more clearly and intuitively demonstrate the alignment relationship between the two coil modules of the implanted coil assembly. The remaining components and assembly structure, such as the positioning connectors of the transmitting coil module, are basically the same as those in the document. Figure 1 The receiving coil module 11 shown is arranged in a mirror image. Therefore, the component structure of the corresponding transmitting coil module can also be understood by referring to the receiving coil module 11 shown in the figure, and will not be described again.

[0042] More specifically, a receiving guard plate 115 protrudes from the outer edge of the top surface of the receiving substrate 112. The receiving guard plate 115 extends circumferentially around the receiving substrate 112 and connects end to end to form a receiving cavity 116 on the top of the receiving substrate 112 that can accommodate the receiving coil body 113. The top of the alignment boss 114 protrudes from the top of the receiving guard plate 115. The receiving guard plate 115 can provide sufficient circumferential structural protection for the receiving coil body 113, preventing the outer edge of the receiving coil body 113 from being bumped by external parts or causing structural interference. At the same time, it can also prevent the receiving coil body 113 from falling out from the side of the receiving guard plate 115, thereby further preventing coil misalignment and ensuring the coil alignment accuracy and power transmission efficiency of the implanted coil assembly.

[0043] Correspondingly, a transmitting guard plate protrudes from the outer edge of the bottom surface of the transmitting substrate. The transmitting guard plate extends circumferentially around the transmitting substrate and connects end to end to form a transmitting cavity at the bottom of the transmitting substrate that can accommodate the transmitting coil body 12. Similar to the receiving guard plate 115 mentioned above, the receiving guard plate 115 can provide sufficient circumferential structural protection for the receiving coil body 113, preventing the outer edge of the receiving coil body 113 from being bumped by external components or causing structural interference. At the same time, it can also prevent the receiving coil body 113 from coming out of the side of the receiving guard plate 115, thereby further preventing coil misalignment and ensuring the coil alignment accuracy and power transmission efficiency of the implanted coil assembly.

[0044] Based on this, the transmitting coil body 12 is bonded and fixed inside the transmitting line cavity. The bonding and fixing method is stable and reliable, and has little impact on the structure of the transmitting coil body 12, thus fully ensuring the working performance of the transmitting coil body 12.

[0045] Generally, the transmitting coil body 12 is arranged in a coil around the axis of the transmitting substrate to form a coiled rotating structure. Adjacent coiled cables are insulated from each other by potting to prevent electromagnetic interference between adjacent cables, thus ensuring stable power transmission and overall coil performance.

[0046] In fact, in specific assembly applications, after the coiled transmitting coil body 12 is placed into the transmitting wire cavity, industrial adhesive with corresponding bonding and curing isolation properties can be used to appropriately fill the transmitting wire cavity, thereby bonding and fixing the transmitting coil body 12 inside the transmitting wire cavity. After the industrial adhesive solidifies, the adhesive filled between two adjacent cables can isolate the two adjacent cables. Thus, the installation effects of fixing and isolating the transmitting coil body 12 can be achieved with only a single adhesive filling process step. This further simplifies the installation process of the implanted coil assembly, improves its assembly installation efficiency, and reduces the process difficulty.

[0047] On the other hand, similar to the arrangement of the transmitting coil body 12 mentioned above, the receiving coil body 113 is bonded and fixed inside the receiving wire cavity 116 to ensure reliable fixation of the receiving coil body 113; at the same time, the receiving coil body 113 is coiled around the axis of the receiving substrate 112, and adjacent coiled cables are insulated from each other by potting glue to prevent electromagnetic interference between adjacent cables of the receiving coil body 113.

[0048] Furthermore, the winding arrangement of the receiving coil body 113 inside the receiving cavity 116 can be directly understood by referring to the winding arrangement of the transmitting coil body 12 inside the transmitting cavity mentioned above, and will not be repeated here.

[0049] It is not difficult to see that, in actual installation, the receiving coil body 113 can be placed into the receiving wire cavity 116 after being coiled, and then the receiving wire cavity 116 can be appropriately filled with industrial adhesive with corresponding bonding and curing isolation properties, thereby bonding and fixing the receiving coil body 113 to the inside of the receiving wire cavity 116. After the industrial adhesive solidifies, the adhesive filled between the two adjacent cables of the receiving coil body 113 can achieve the isolation of the two adjacent cables. Thus, the installation effects of fixing and isolating the receiving coil body 113 can be achieved with only a single process step of adhesive filling. This further simplifies the installation process of the implanted coil assembly, improves its assembly installation efficiency, and reduces the process difficulty.

[0050] Furthermore, considering the application requirements under most working conditions and the ability of the implantable coil assembly to achieve a relatively ideal working state, in practical applications, there are at least three reference connectors 111, and each reference connector 111 is evenly distributed along the circumference of the receiving coil module 11; similarly, there are at least three positioning connectors, and each positioning connector is evenly distributed along the circumference of the transmitting coil module. This ensures that the receiving coil module 11 and the transmitting coil module each have three relatively stable mounting anchor points, thereby guaranteeing reliable alignment and assembly of each coil module and stable placement at the corresponding location on the patient's body.

[0051] Of course, in practical applications, the number and arrangement of the reference connector 111 and the positioning connector can be flexibly adjusted according to specific working conditions. In principle, any arrangement that can meet the patient's medical needs is acceptable. However, considering that both the receiving coil module 11 and the transmitting coil module are disc-shaped structures in practical applications, the circumferentially distributed structure of the three sets of connectors mentioned above is still a relatively ideal component arrangement under most application conditions.

[0052] Furthermore, the sidewalls and bottomwalls of the reference connector 111 are recessed with reference grooves 117 capable of accommodating surgical sutures, and the sidewalls and topwalls of the positioning connector are recessed with positioning grooves capable of accommodating surgical sutures. The end openings of the reference grooves 117 and the positioning grooves are aligned and connected, so that after the reference connector 111 and the positioning connector are aligned and assembled to form a connecting assembly, a circumferentially extending groove is formed on the outer peripheral surface of the connecting assembly. This allows the surgical sutures to be embedded into the grooves of the corresponding connecting assemblies and smoothly wrapped and sutured on the outer periphery of the corresponding connecting assemblies when the receiving coil module 11 and the transmitting coil module are subsequently aligned and sutured with surgical sutures. This prevents the surgical sutures from slipping off the outer periphery of each connector, thereby further optimizing the assembly structure stability of the receiving coil module 11 and the transmitting coil module, making the installation and arrangement of the implanted coil assembly more stable and reliable.

[0053] In summary, the implantable coil assembly provided by this utility model, during its operation, after the receiving coil module is implanted into the patient's body, located below the patient's skin tissue, can then have the transmitting coil module correspondingly fixed to the patient's skin surface, ensuring the positions of the transmitting and receiving coil modules align. Simultaneously, the positioning connector and the reference connector are aligned and snapped together through the patient's skin tissue, thus achieving accurate alignment and reliable connection between the transmitting and receiving coil modules. Afterwards, surgical sutures can be used to reliably suture and fix the current fitting structure of the receiving and transmitting coil modules. The specific suture location can be chosen at the snap-fit ​​assembly of the reference and positioning connectors; that is, the surgical suture is wrapped around the snap-fit ​​assembly structure of the reference and positioning connectors and sutured in place. This method utilizes surgical sutures to further securely fix the reference connector and the positioning connector, making their alignment and assembly structure more robust and reliable. This, in turn, ensures a more stable and precise alignment between the transmitting coil module and the receiving coil module, guaranteeing more sensitive and efficient electromagnetic wave transmission and induction between them. It avoids coil loosening and misalignment, as well as resulting electromagnetic wave frequency abnormalities and abnormal coil overheating. Ultimately, this effectively ensures a stable power supply and smooth operation for implantable medical devices such as pacemakers, brain stimulators, and artificial hearts compatible with the implantable coil assembly, thus effectively guaranteeing the patient's health and the smooth progress of related medical activities.

Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that those skilled in the art can make several improvements and modifications to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
