Description

Technical Field

[0001] This application relates to the field of implantable device technology, and more particularly to an implantable neural signaling device. Background Technology

[0002] Currently, neural signaling systems incorporating implantable neural signalers are widely used in the medical field. In these systems, the implantable neural signalers are inserted into the patient's body to treat affected areas and collect relevant signals. However, currently, the communication and stimulation acquisition components of implantable neural signalers are housed in the same casing, resulting in a large casing size. Since the casing needs to be implanted into the skull, an excessively large casing can cause significant damage to the implantation area. Furthermore, existing technologies also employ a top-to-bottom stacking design for the communication and stimulation acquisition components, which leads to complex internal wiring and affects the overall height of the implanted device.

[0014] In some embodiments, the actuating component further includes an electrode cap that covers the proximal end of the flexible electrode, and the electrode cap has a pressure connector on its side facing the flexible electrode, the pressure connector being used to apply a force to the flexible electrode to cause it to resist the first feedthrough.

[0015] In some embodiments, the pressure connector includes a seat, a spring pin, and a seal. The seat is connected to the distal side of the electrode cover and has a mounting hole. The spring pin is disposed in the mounting hole, and the seal is disposed on the seat and surrounds the outer periphery of the spring pin.

[0016] In some embodiments, at least a portion of the first housing is covered with a first buffer shell, the first buffer shell being located on the side of the first housing away from the first feeder, and the second housing is covered with a second buffer shell, the first buffer shell and the second buffer shell being mounted on each other, or the first buffer shell and the second buffer shell being integrally formed.

[0017] In some embodiments, the first housing is connected to a plurality of connecting arms, which are used to cooperate to fix at least a portion of the first housing to the first organism, and the plurality of connecting arms are arranged at intervals around the outside of the first housing.

[0018] In some embodiments, the functional component further includes a circuit board disposed within the first housing and a power supply module, the power supply module being electrically connected to the circuit board; wherein the power supply module includes a power supply battery and / or a power supply circuit.

It should also be understood that terms defined in general dictionaries should be interpreted as having meanings consistent with their meanings in the context of the relevant art, and not as idealized or highly formalized, unless expressly defined herein. Techniques, methods, and apparatus known to one of ordinary skill in the art may not be discussed in detail, but where appropriate, such techniques, methods, and apparatus should be considered part of the specification.

[0045] This application provides an implantable neural signaling device. For example... Figures 1 to 3 As shown, the implantable neural signaling device includes an action component 1 and a communication component 2. The action component 1 includes a first housing 11 and an action module disposed within the first housing 11. At least a portion of the first housing 11 is implanted into a first organism. The action module includes a stimulation module and / or a acquisition module. The stimulation module is used to apply electrical stimulation to the target tissue, and the acquisition module is used to acquire the potential signal of the target tissue. The communication component 2 includes a second housing 21 and a communication module 22 disposed within the second housing 21. The first housing 11 and the second housing 21 are connected. The action module is electrically connected to the communication module 22. The second housing 21 is implanted into a second organism, which is located outside the first organism.

[0046] By placing the aforementioned functional module inside the first housing 11 and the communication module 22 inside the second housing 21, the functional module and the communication module 22 can be placed in different housings. The first housing 11 and the second housing 21 can be understood as two independent housings with a connection between them. By setting the independent first housing 11 and the second housing 21, the modularization of the functional component 1 and the communication component 2 can be achieved. After the functional component 1 and the communication component 2 are assembled separately, the functional component 1 and the communication component 2 are then assembled together, such as connecting the first housing 11 and the second housing 21, and making electrical connections between the functional module and the communication module 22.

[0047] The first housing 11 is at least partially implanted into the first organism, and the second housing 21 is implanted into the second organism located outside the first organism. This allows the communication module 22 inside the second housing 21 to be located outside the first organism, thereby reducing the area of ​​the slot on the first organism and thus reducing damage.

[0048] Furthermore, compared to the method of implanting the communication module 22 into the first organism, the present application implants the communication module 22 into a second organism located outside the first organism, which can reduce the interference received by the communication module 22 and achieve the purpose of improving the signal strength and data transmission efficiency of the communication module 22.

[0049] An inner support can be provided inside the first housing 11 to support electronic components inside the first housing 11, such as the functional module inside the first housing 11, or the circuit board 13 and / or power supply module 14 inside the first housing 11 as described below. The inner support can be used to install and fix the electronic components inside the first housing 11 to ensure the stability of the internal structure of the functional component 1.

[0050] The first housing 11 can be constructed as an internally sealed structure formed by connecting multiple sub-housings. For example, the first housing 11 is formed by splicing two sub-housings to form an internally sealed structure.

[0051] The first housing 11 and the second housing 21 can be sealed together by a sealing connector. The sealing connector can be made of epoxy resin or other insulating materials. This application does not make any specific limitation on this.

[0052] The first housing 11 can be cylindrical, frustum-shaped, or other shapes. The bottom surface of the second housing 21 can be circular or elliptical. By separately arranging the first housing 11 of the functional component 1 and the second housing 21 of the communication component 2, the functional module and the communication module 22 are placed in different housings. This allows only at least a portion of the first housing 11 to be implanted into the first organism, effectively reducing the volume of the implantable neural signal device and minimizing damage to the implantation area. Furthermore, the communication module 22 of the communication component 2 is located within the second housing 21 implanted in the second organism, which improves the signal strength and data transmission efficiency of the communication module 22. In addition, compared to the current scheme where the communication part and the stimulation acquisition part are stacked from top to bottom, this application, by designing two independent housings, namely the connected first housing 11 and the second housing 21, can reduce the overall structural thickness of the implantable neural signal device and reduce the complexity of the internal wiring, simplifying the structural design of the implantable neural signal device and making the structure more rational.

[0053] In some embodiments, the first housing 11 has a first receiving cavity for accommodating the functional module, and the second housing 21 has a second receiving cavity for accommodating the communication module 22, wherein the first receiving cavity and the second receiving cavity are arranged independently.

[0054] In this way, the functional module and the communication module 22 can be accommodated in the first and second accommodating cavities, which are independently set up, so that the functional module and the communication module 22 can be set up independently. Compared with implanting the communication module 22 into the first biological body, implanting the communication module 22 into the second biological body outside the first biological body is beneficial to reduce the size of the first shell 11 implanted into the first biological body, thereby reducing damage to the implantation area.

[0055] The independent arrangement of the first and second accommodating cavities can be understood as the fact that the first and second accommodating cavities are not connected, so as to achieve the independence of the arrangement of the functional component 1 and the communication component 2.

[0056] In some embodiments, such as Figures 1 to 4 As shown, the implantable neural signaling device also includes a flexible electrode 3, which can be made of a flexible material. The proximal end 31 of the flexible electrode 3 is electrically connected to the action module, and the distal end 32 of the flexible electrode 3 is provided with an electrode site for implantation into the target tissue, so as to apply electrical stimulation to the target tissue and / or collect the potential signal of the target tissue through the electrode site. Using the above-mentioned flexible electrode 3 can better adapt to the shape and movement of neural tissue, thereby reducing mechanical pressure and damage to surrounding tissues.

[0057] The aforementioned flexible electrode 3 can be connected to the distal side of the first housing 11 placed within the first biological body, or it can be connected to the side of the first housing 11, where the side can be understood as the surface adjacent to the distal side. For example, as... Figure 4 As shown, Figure 4 The flexible electrode 3 shown is connected to the distal side of the first housing 11 placed within the first organism.

[0058] The proximal end 31 of the aforementioned flexible electrode 3 is electrically connected to the action module. The electrode site on the distal end 32, which is electrically connected to the proximal end 31, can realize the information acquisition of the target tissue and the function of electrical stimulation.

[0059] In some embodiments, such as Figures 1 to 4 As shown, the flexible electrode 3 is constructed in a sheet shape, and the flexible electrode 3 also includes a lead wire connection portion 33. The proximal end portion 31 and the distal end portion 32 are electrically connected through the lead wire connection portion 33. The proximal end portion 31, the lead wire connection portion 33, and the distal end portion 32 are arranged sequentially along the length direction of the flexible electrode 3.

[0060] The flexible electrode 3 described above can adopt a multi-layer structure, such as being formed by stacked insulating and conductive layers. This application does not specifically limit the structure of the flexible electrode 3.

[0061] In some embodiments, such as Figures 1 to 4 As shown, the first shell 11 includes a first part and a second part connected together. The first part is implanted into a first organism, the second part is implanted into a second organism, and the second shell 21 is connected to the second part.

[0062] Thus, the first shell 11 can be partially implanted into the first biological body by implanting the first part into the first biological body and the second part into the second biological body, thereby effectively reducing the volume of the first shell 11 implanted into the first biological body and thus reducing the damage to the implantation area.

[0063] The first housing 11 and the second housing 21 can be detachably connected or welded together. This application does not make any specific limitation on this, as long as the sealing of the connection between the first housing 11 and the second housing 21 can be guaranteed.

[0064] The shape of the first part can be cylindrical, frustum-shaped, etc. When the shape of the first part is cylindrical, the diameter of the first part can be in the range of 28mm to 32mm, preferably 30mm.

[0065] The first part and / or the second part may be provided with positioning surfaces, which are used to abut against the first organism to achieve positioning of the first shell 11.

[0066] In some embodiments, the thickness of the second shell 21 is less than the thickness of the first shell 11, so as to minimize the thickness of the second shell 21 implanted in the second organism, so that the first shell 11 and the second shell 21 can be implanted more reasonably into the second organism, reducing damage to the second organism.

[0067] Specifically, the near side of the first housing 11 and the near side of the second housing 21 can be located on the same plane, that is, the upper surface of the first housing 11 and the upper surface of the second housing 21 can be flush.

[0068] The thickness of the first housing 11 can range from 6 mm to 8 mm. The thickness of the second housing 21 can range from 2 mm to 4 mm, preferably 3 mm.

[0069] The edges of the first housing 11 and the second housing 21 can be smoothly transitioned to reduce damage to the target tissue in the implantation area.

[0070] In some embodiments, the first organism is the skull, the second organism is located between the skull and the scalp, and the first shell 11 is connected to the outer surface of the skull to fix it to the skull.

[0071] In some embodiments, at least the first shell 11 implanted in the first organism is made of a metallic material; and / or, the second shell 21 is made of a non-metallic material.

[0072] In this way, the interference of metal materials on the communication module 22 inside the second housing 21 can be reduced, that is, the signal shielding or eddy currents caused by metal can be reduced, thereby improving the signal strength and data transmission efficiency of the communication module 22.

[0073] The metal material used for the first shell 11, which is at least implanted in the first biological body, can be titanium alloy or other metal materials, such as stainless steel or aluminum alloy. These materials have excellent strength, rigidity and biocompatibility. This application does not specifically limit the metal material used for the first shell 11, as long as it can be implanted in the biological body.

[0074] Optionally, the first shell 11 not implanted in the first organism may be made of a non-metallic material, which should have good corrosion resistance, biocompatibility and processability, such as silicone.

[0075] Optionally, the first shell 11 not implanted in the first biological body may be made of a metallic material. Specifically, the first shell 11 may be made entirely of the same metallic material, such as a titanium alloy.

[0076] In some embodiments, such as Figure 4 and Figure 5 As shown, the functional component 1 also includes a first feedthrough 4 disposed on the first housing 11, and the functional module is electrically connected to the proximal end 31 of the flexible electrode 3 through the first feedthrough 4. In this way, a stable electrical connection between the flexible electrode 3 and the functional module can be achieved through the first feedthrough 4.

[0077] The first housing 11 may be provided with a first feed passage groove, and the first feed passage component 4 may be installed in the first feed passage groove. The first feed passage groove can be used to stably install the first feed passage component 4 and make the structure of the functional component 1 more reasonable.

[0078] The aforementioned first feedthrough component 4 may include a mounting base, an insulating sleeve, and a conductor. The mounting base is sealably connected to the first housing 11, specifically by welding. The insulating sleeve is embedded in the mounting base, and the conductor extends out of the first housing 11 through the insulating sleeve to electrically connect with the communication module 22 inside the second housing 21. The insulating sleeve may be made of ceramic or other insulating materials.

[0079] In some embodiments, such as Figure 4As shown, the first housing 11 has a distal side that is placed within the first organism, and the first feedthrough 4 is mounted on the distal side of the first housing 11. By mounting the first feedthrough 4 on the distal side of the first housing 11, the flexible electrode 3 connected to the first feedthrough 4 can be brought closer to the target tissue, which is beneficial for the implantation of the flexible electrode 3.

[0080] In some other embodiments, such as Figure 5 As shown, the first feeder 4 can be disposed on the side of the first housing 11 adjacent to the far side.

[0081] Specifically, a stepped mounting structure may be formed on the first housing 11, the stepped mounting structure having side walls and a bottom wall, and the first feeder 4 may be located on the bottom wall of the mounting structure.

[0082] In some embodiments, the proximal end 31 of the flexible electrode 3 is sealed to the first housing 11 implanted in the first biological body to prevent external tissue intrusion, thereby achieving a good sealing effect on the flexible electrode 3 and effectively improving the sealing performance.

[0083] Optionally, the proximal end 31 of the flexible electrode 3 and the first housing 11 implanted in the first biological body can be sealed by injecting insulating material.

[0084] Optionally, the proximal end 31 of the flexible electrode 3 and the first housing 11 implanted in the first biological body can be sealed by coating with an insulating material.

[0085] Optionally, the aforementioned insulating material may be epoxy resin or other insulating materials, and this application does not specifically limit it.

[0086] In some embodiments, such as Figure 7 As shown, the action component 1 also includes an electrode cover 5, which covers the proximal end 31 of the flexible electrode 3. A pressure connector 6 is provided on the side of the electrode cover 5 facing the flexible electrode 3. The pressure connector 6 is used to apply a force to the flexible electrode 3 to make it abut against the first feeder 4.

[0087] Thus, the pressure connector 6 can apply a stable force to the flexible electrode 3, enabling the flexible electrode 3 to stably abut against the first feeder 4, effectively improving the conductivity at the contact point between the flexible electrode 3 and the first feeder 4, thereby ensuring that the flexible electrode 3 can be stably electrically connected to the working module through the first feeder 4.

[0088] When the action module includes a stimulation module, a simulation operation is first performed by electrically connecting a simulator to the flexible electrode 3. After confirming the parameters in the simulation operation, the implantable neural signal device is then used for the formal implantation operation. Therefore, the installation operation of the flexible electrode 3 and the action component 1 is performed before the formal implantation operation. By using the aforementioned pressure connector 6, when the flexible electrode 3 is installed on the action component 1, a force is applied to the flexible electrode 3 to make it resist the first feedthrough 4, thereby ensuring that the flexible electrode 3 can achieve a stable electrical connection with the action module through the first feedthrough 4.

[0089] In some embodiments, the pressure connector 6 can be used to apply an elastic force to the flexible electrode 3, so that the flexible electrode 3 can stably abut against the first feedthrough member 4. In some other embodiments, the pressure connector 6 can move under the control of a control signal to act on the flexible electrode 3, so as to apply a force to the flexible electrode 3 to make it abut against the first feedthrough member 4. For example, the pressure connector 6 includes a telescopic structure, which can perform telescopic movement after receiving a control signal to act on the flexible electrode 3.

[0090] The electrode cover 5 can be installed on the distal side of the first housing 11. Specifically, the electrode cover 5 can be detachably connected to the first housing 11, such as by pivoting, or by having mounting holes in which mounting screws can be installed to facilitate detachment from the first housing 11. In some other embodiments, the electrode cover 5 can be slidably connected to the first housing 11. This application does not specifically limit the connection method between the electrode cover 5 and the first housing 11.

[0091] The electrode cover 5 can be made of one or more of the following materials: polyetheretherketone, epoxy resin.

[0092] After the flexible electrode 3 and the first feedthrough component 4 are connected, insulating material can be used for filling to ensure the installation and sealing of the flexible electrode 3 and the first feedthrough component 4.

[0093] In some embodiments, such as Figure 7 As shown, the pressure connector 6 includes a seat 61, a spring pin 62, and a seal 63. The seat 61 is connected to the far side of the electrode cover 5, and the seat 61 is provided with a mounting hole. The spring pin 62 is disposed in the mounting hole, and the seal 63 is disposed on the seat 61 and surrounds the outer periphery of the spring pin 62.

[0094] In this way, a stable force can be applied to the flexible electrode 3 through the spring pin 62 installed on the base 61, and the sealing member 63 can ensure the installation sealing between the pressure connector 6, the flexible electrode 3 and the first feed passage member 4.

[0095] The aforementioned spring pin 62 can be configured one-to-one with the contact points of the proximal end 31 of the flexible electrode 3 to ensure that each contact point of the proximal end 31 of the flexible electrode 3 can stably abut against the first feeder 4, thereby ensuring the connection stability at the contact point.

[0096] In some embodiments, such as Figures 1 to 3 As shown, at least part of the first housing 11 is covered with a first buffer shell 8, the first buffer shell 8 is located on the side of the first housing 11 away from the first feeder 4, the second housing 21 is covered with a second buffer shell, the first buffer shell 8 and the second buffer shell are installed on each other, or the first buffer shell 8 and the second buffer shell are integrally formed.

[0097] Thus, by setting the first buffer shell 8 and the second buffer shell, the implantation area can be buffered and protected, thereby reducing damage to the target tissue.

[0098] The first buffer shell 8 and the second buffer shell mentioned above can be made of a flexible and elastic material, and the material should be corrosion resistant, biocompatible and processable, such as silicone.

[0099] The first buffer shell 8 can cover part or all of the exterior of the first shell 11, and the second buffer shell can cover part or all of the exterior of the second shell 21.

[0100] In some embodiments, such as Figures 1 to 4 As shown, a plurality of connecting arms 12 are connected to the first housing 11. The plurality of connecting arms 12 are used to cooperate to fix at least part of the first housing 11 into the first organism, and the plurality of connecting arms 12 are arranged at intervals around the outer side of the first housing 11.

[0101] In this way, the first housing 11 can be stably fixed to the first organism through the connecting arm 12, thereby achieving the installation stability of the functional component 1.

[0102] Optionally, the connecting arm 12 can be integrally formed with the first housing 11, or it can be detachably connected to the first housing 11. This application does not specifically limit this. When the connecting arm 12 is detachably connected to the first housing 11, the connecting arm 12 can be independent of the first housing 11, thereby allowing the length of the connecting arm 12 to be adjusted as needed, providing the operator with a variety of size options.

[0103] Optionally, the connecting arm 12 can be made of a metal material, such as titanium alloy, or other metal materials, such as stainless steel or aluminum alloy. These materials have excellent strength, rigidity and biocompatibility. This application does not specify the metal material used for the connecting arm 12, as long as it can be implanted into a living organism.

[0104] Optionally, the end of the connecting arm 12 away from the first housing 11 may be provided with a mounting hole, and a fastener is inserted into the mounting hole to fix the first housing 11 to the first organism. For example, if the fastener is a bolt, the connection between the first housing 11 and the first organism can be achieved by connecting the bolt to the first organism.

[0105] In some embodiments, such as Figure 3 As shown, the functional component 1 also includes a circuit board 13 and a power supply module 14 disposed within the first housing 11. The power supply module 14 is electrically connected to the circuit board 13. The power supply module 14 includes a power supply battery and / or a power supply circuit. The functional module can be disposed on the circuit board 13 or can be independent of the circuit board 13 and electrically connected to the circuit board 13.

[0106] Thus, the power supply module 14 can be used to continuously supply power using a power supply battery, or the power supply circuit can be used to charge while in use.

[0107] The circuit board 13 and the power supply module 14 can be fixed to the first housing 11 via an inner bracket, or they can be fixed and installed by other brackets. This application does not make any specific limitation on this.

[0108] In some embodiments, such as Figure 2 and Figure 3 As shown, the communication module 22 includes a charging coil 23 and / or a Bluetooth module 24 to power the power supply module 14 via the charging coil 23 and / or to transmit information to the function module via the Bluetooth module 24.

[0109] When the communication module 22 includes a charging coil 23 and a Bluetooth module 24, the charging coil 23 and the Bluetooth module 24 do not need to be placed inside the first housing 11. This achieves the goal of minimizing the size of the first housing 11, thereby effectively reducing the volume of the first housing 11 implanted into the first biological body and reducing damage to the implantation area.

[0110] When the communication module 22 does not include the charging coil 23, the charging coil 23 can be disposed inside the first housing 11 so as to directly supply power to the circuit board 13 and the power supply module 14 inside the first housing 11 through the charging coil 23.

[0111] When the communication module 22 does not include the Bluetooth module 24, the Bluetooth module 24 can be disposed inside the first housing 11 to directly communicate with the circuit board 13 inside the first housing 11.

[0112] In some embodiments, such as Figure 2 and Figure 3As shown, the communication module 22 includes a charging coil 23 and a Bluetooth module 24. The antenna of the Bluetooth module 24 is wound around the outer periphery of the charging coil 23 and is sealed and fixed to the charging coil 23 in the second housing 21.

[0113] The above-mentioned charging coil 23 and Bluetooth module 24 have a reasonable structural design, which can minimize the thickness of the second housing 21, thereby reducing the damage to the implantation area.

[0114] In some embodiments, such as Figure 6 As shown, a second feedthrough 7 is provided on the side of the first housing 11 facing the second housing 21, and the function module is electrically connected to the communication module 22 through the second feedthrough 7. In this way, a stable connection between the communication module 22 and the function module can be achieved through the second feedthrough 7.

[0115] Optionally, the first housing 11 may be provided with a second feed passage, and the second feed passage 7 may be installed in the second feed passage. The second feed passage can be used to stably install the second feed passage 7 and make the structural design of the functional component 1 more reasonable.

[0116] In some embodiments, a connecting portion is provided on the side of the first housing 11 facing the second housing 21, and the second housing 21 is connected to the connecting portion. In this way, the first housing 11 and the second housing 21 can be stably connected through the connecting portion.

[0117] The aforementioned connecting part can be integrally formed with the first housing 11, or it can be detachably connected to the first housing 11. This application does not make specific limitations on this, as long as a stable connection between the first housing 11 and the second housing 21 can be achieved.

[0118] In some embodiments, such as Figure 6 As shown, the first housing 11 has a stepped portion on the side facing the second housing 21. The stepped portion has a side wall and a bottom wall. The second housing 21 abuts against the side wall of the stepped portion, and the bottom of the second housing 21 is supported by the bottom wall of the stepped portion. In this way, a stable connection between the first housing 11 and the second housing 21 can be achieved through the side wall and bottom wall of the stepped portion.
