Description

Technical Field

[0001] The present invention relates to the technical field of pulse generators, and in particular to a pulse generator. Background Art

[0002] Neuroelectric stimulation is a commonly used method for treating neurological disorders and rehabilitation of neurological injuries. The neuroelectric stimulation system applies electrical stimulation to relevant parts through pulse generators and electrodes implanted in the body. Among them, the pulse generator is mainly used to generate electrical stimulation, and the electrical stimulation signal is released into the patient's brain through the stimulation electrodes to help the patient recover. Among them, the pulse generator includes a titanium shell, in which core components such as circuit boards and batteries are installed. The top of the titanium shell is a transparent connector, and a channel module is provided in the connector for connecting the electrode wire. When the electrode wire is inserted into the channel module inside the connector, it is necessary to observe the insertion position of the electrode wire with the naked eye to ensure a reliable electrical connection. Therefore, the main body of the connector needs to be made of a transparent material.

[0003] The connector of the traditional stimulator uses epoxy glue to form the transparent body of the connector. On the one hand, the transparent structure is formed by epoxy curing, which is easy to observe; on the other hand, the seal is formed between the cured epoxy resin and the titanium shell to prevent external impurities such as patient body fluids from entering the pulse generator. However, epoxy resin has shrinkage stress during the curing process, which causes the titanium shell to deform. When the shrinkage stress is maintained for a long time, it will cause microcracks on the surface of the epoxy resin and the titanium shell, and even cracks, causing the epoxy to lose its function of protecting internal components.

[0004] Based on this, a pulse generator is urgently needed to solve the above-mentioned problems. Summary of the invention

[0005] Based on the above, the purpose of the present invention is to provide a pulse generator to solve the problem that in the related technology, there are few components and large gaps in the epoxy resin filling area where the channel module is not set. Therefore, the filling amount of epoxy resin is large, resulting in large deformation stress of the epoxy resin after curing, which forms micro-cracks between the epoxy resin and the titanium shell. When these cracks spread and connect, leakage channels will be formed, causing body fluids to penetrate into components such as the channel module.

[0006] To achieve the above object, the present invention adopts the following technical solutions:

[0007] A pulse generator, comprising:

[0008] Pulse generator body,

[0009] A connecting component, the connecting component includes a head, a channel module and a reinforcing structure, the channel module is installed on the top surface of the pulse generator body, the reinforcing structure is installed in at least a part of the top surface of the pulse generator body where the channel module is not installed, the head is formed on the top surface of the pulse generator body by glue pouring, and the glue pouring medium forming the head covers the reinforcing structure and the pulse generator body.

[0010] As a preferred technical solution for a pulse generator, a receiving cavity is formed between the reinforcing structure and the pulse generator body, and the glue potting medium is filled into the receiving cavity.

[0011] As a preferred technical solution for a pulse generator, the reinforcing structure is welded, bonded, clamped or connected to the top surface of the pulse generator body via fasteners.

[0012] As a preferred technical solution for a pulse generator, one of the reinforcing structure and the top surface of the pulse generator body is provided with a positioning column, and the other is provided with a positioning groove, and the positioning column can be inserted into the positioning groove.

[0013] As a preferred technical solution for a pulse generator, the reinforcing structural member is a wave-shaped reinforcing sheet, and a receiving cavity is formed between the wave crest of the reinforcing sheet and the top surface of the pulse generator body.

[0014] As a preferred technical solution for a pulse generator, the wave-shaped reinforcement sheet is provided with a first flow hole.

[0015] As a preferred technical solution for a pulse generator, the reinforcing structural member is mushroom-shaped, and includes an umbrella-shaped portion and a rod portion. One end of the rod portion is connected to the umbrella-shaped portion, and the other end is connected to the top surface of the pulse generator body. A accommodating cavity is formed between the umbrella-shaped portion and the top surface of the pulse generator body.

[0016] As a preferred technical solution for a pulse generator, the reinforcing structural member includes a plurality of wavy strips, and the plurality of wavy strips are evenly arranged in the area of ​​the top surface of the pulse generator body where the channel module is not installed, the troughs of the wavy strips are welded to the top surface of the pulse generator body, and a accommodating cavity is formed between the crests of the wavy strips and the top surface of the pulse generator body.

[0017] As a preferred technical solution for a pulse generator, the reinforcing structural member is a flange, and an annular connecting plate is provided on one side of the flange. The connecting plate is connected to the top surface of the pulse generator body at one end away from the flange, and a accommodating cavity is formed between the flange and the top surface of the pulse generator body.

[0018] As a preferred technical solution of a pulse generator, a second flow hole is provided in the middle of the flange.

[0019] As a preferred technical solution for a pulse generator, the reinforcing structural member includes a connecting column, the connecting column is installed on the top surface of the pulse generator body, and the connecting column has a plurality of fixing layers spaced apart in the axial direction.

[0020] As a preferred technical solution for a pulse generator, the material of the glue-filling medium is a thermosetting polymer material.

[0021] Alternatively, the material of the glue-filling medium is a mixture of a thermosetting polymer material and a silicone material.

[0022] The beneficial effects of the present invention are:

[0023] The present invention provides a pulse generator, wherein a channel module is installed on the top surface of the pulse generator body. The area on the top surface of the pulse generator body where the channel module is installed has, on the one hand, a relatively large number of parts and a small amount of glue medium forming the head, so that the shrinkage stress is relatively small. On the other hand, the channel module fixing structure is welded to the top of the body, thereby enhancing the rigidity of the area where the channel module is installed, so that the area where the channel module is installed will not be deformed. A reinforcing structural member is installed in at least part of the area on the top surface of the pulse generator body where the channel module is not installed. When the glue medium is filled into the head, the reinforcing structural member increases the number of parts in the area on the top surface of the pulse generator body where the channel module is not installed.

On the other hand, the reinforcing structural member is installed on the top surface of the pulse generator body, thereby effectively enhancing the rigidity of the top surface of the pulse generator body, increasing the difficulty of deformation of the top surface of the pulse generator body, and further preventing the glue medium from shrinking and deforming after curing.

[0038] Embodiment 1

[0039] The following is a brief description of the technical field and related terms of the embodiments of the present application.

[0040] Implantable medical systems include implantable neural stimulation systems, implantable cardiac stimulation systems (also known as pacemakers), implantable drug delivery systems (IDDS), and lead switching systems. Examples of implantable neural stimulation systems include deep brain stimulation (DBS), implantable cortical nerve stimulation (CNS), implantable spinal cord stimulation (SCS), implantable sacral nerve stimulation (SNS), and implantable vagus nerve stimulation (VNS).

[0041] The implantable neural electrical stimulation system includes a stimulator implanted in the patient's body (i.e., an implantable neural stimulator) and a programmable device disposed outside the patient's body. In other words, the stimulator is a medical device, or in other words, the medical device includes the stimulator. The relevant neural regulation technology mainly implants electrodes (electrodes, for example, in the form of electrode wires) in specific parts of the tissues of the organism (i.e., target points) through stereotactic surgery, and emits discharge pulses to the target points through the electrodes to regulate the electrical activity and function of the corresponding neural structures and networks, thereby improving symptoms and relieving pain.

[0042] As an example, DBS includes an IPG (Implantable Pulse Generator), an extension wire and an electrode wire, and the IPG is connected to the electrode wire via the extension wire. The IPG is implanted in the patient's body, for example, in the patient's chest or other body parts.

[0043] As another example, DBS includes an IPG and an electrode lead, and the IPG is directly connected to the electrode lead. The IPG is implanted in the patient's head, for example, a groove is made in the patient's skull, and then the IPG is installed in the groove of the skull. In this case, the IPG may not protrude from the outer surface of the skull, or may partially protrude from the outer surface of the skull.

[0044] The IPG responds to the program-controlled instructions sent by the program-controlled device, and relies on sealed batteries and circuits to provide controllable electrical stimulation therapy (or electrical stimulation energy) to the tissues in the body. The IPG delivers one or more controllable specific electrical stimulations to specific areas of the tissues in the body through electrode wires.

[0045] In some embodiments, the extension lead is used in conjunction with the IPG as a transmission medium for electrical stimulation, and transmits the electrical stimulation generated by the IPG to the electrode lead.

[0046] In some embodiments, the electrical stimulation may be delivered in the form of a pulse signal or in the form of a non-pulse signal. For example, the electrical stimulation may be delivered as a signal having various waveform shapes, frequencies, and amplitudes. Thus, the electrical stimulation in the form of a non-pulse signal may be a continuous signal, which may have a sinusoidal waveform or other continuous waveform.

[0047] After receiving the electrical stimulation transmitted by the IPG or the extension wire, the electrode wire delivers the electrical stimulation to a specific area of ​​the tissue in the body through a plurality of electrode contacts. The stimulator is provided with, for example, one or more electrode wires on one side or both sides, and a plurality of electrode contacts are provided on the electrode wire, and the electrode contacts can be arranged uniformly or non-uniformly in the circumferential direction of the electrode wire. As an example, the electrode contacts can be arranged in an array of 4 rows and 3 columns (a total of 12 electrode contacts) in the circumferential direction of the electrode wire. The electrode contacts can include stimulation electrode contacts and / or collection electrode contacts. The electrode contacts can be in the shape of sheets, rings, dots, etc., for example.

[0048] In some embodiments, the stimulated in vivo tissue may be the patient's brain tissue, and the stimulated site may be a specific site of the brain tissue. When the patient's disease type is different, the stimulated site is generally different, and the number of stimulation contacts (single source or multiple sources), the use of one or more (single channel or multiple channels) of specific electrical stimulation, and the stimulation parameters (values) are also different.

[0049] The embodiments of the present application do not limit the types of diseases that can be used, and can be diseases that can be used for deep brain stimulation (DBS), spinal cord stimulation (SCS), sacral nerve stimulation, gastric stimulation, peripheral nerve stimulation, and functional electrical stimulation. Among them, DBS can be used to treat or manage diseases including, but not limited to: spastic diseases (e.g., epilepsy), pain, migraine, mental illness (e.g., major depression), bipolar disorder, anxiety, post-traumatic stress disorder, mild depression, obsessive-compulsive disorder, behavioral disorders, mood disorders, memory disorders, mental state disorders, movement disorders (e.g., essential tremor or Parkinson's disease), Huntington's disease, Alzheimer's disease, drug addiction, autism or other neurological or psychiatric diseases and injuries.

[0050] In the embodiment of the present application, when the programmable device and the stimulator establish a programmable connection, the programmable device can be used to adjust one or more stimulation parameters of the stimulator (or one or more stimulation parameters of the pulse generator, different stimulation parameters correspond to different electrical stimulations), and the stimulator can also sense the patient's electrophysiological activities to collect electrophysiological signals, and the collected electrophysiological signals can be used to continue to adjust the stimulation parameters of the stimulator, thereby realizing closed-loop control (or adaptive adjustment) of the stimulation parameters.

[0051] The stimulation parameters may include at least one of the following: the electrode contact identification used to deliver electrical stimulation (for example, electrode contact #2 and electrode contact #3), frequency (for example, the number of electrical stimulation pulse signals within a unit time of 1s, in Hz), pulse width (the duration of each pulse, in μs), amplitude (generally expressed in voltage, that is, the intensity of each pulse, in V), timing (for example, it can be continuous or burst, and burst refers to discontinuous timing behavior composed of multiple processes), stimulation mode (including one or more of current mode, voltage mode, timed stimulation mode and cyclic stimulation mode), upper and lower limits controlled by the doctor (the range that can be adjusted by the doctor) and upper and lower limits controlled by the patient (the range that can be adjusted autonomously by the patient).

[0052] In some embodiments, various stimulation parameters of the stimulator can be adjusted in current mode or voltage mode.

[0053] Programmable devices may include doctor programmable devices (i.e. programmable devices used by doctors) and / or patient programmable devices (i.e. programmable devices used by patients). Doctor programmable devices are, for example, tablet computers, laptop computers, desktop computers, mobile phones and other intelligent terminal devices equipped with programmable software. Patient programmable devices are, for example, tablet computers, laptop computers, desktop computers, mobile phones and other intelligent terminal devices equipped with programmable software. Patient programmable devices may also be other electronic devices with programmable functions (e.g., chargers with programmable functions, electrophysiological acquisition devices, etc.).

[0054] like Figure 1-Figure 3 As shown, this embodiment provides a pulse generator, which includes a pulse generator body 1 and a connecting assembly 2, wherein the connecting assembly 2 includes a head 21, a channel module 22 and a reinforcing structure 23, wherein the channel module 22 is installed on the top surface of the pulse generator body 1, and the reinforcing structure 23 is installed in at least part of the top surface of the pulse generator body 1 where the channel module 22 is not installed, and the top surface of the pulse generator body 1 is formed into the head 21 by glue pouring, and the glue pouring medium forming the head 21 covers the reinforcing structure 23 and the pulse generator body 1. It should be noted that the pulse generator body 1 includes a titanium shell, in which core components such as a circuit board and a battery are installed, and the channel module 22 is used to connect external electrode wires, and the channel module 22 is electrically connected to core components such as the circuit board and the battery.

[0055] Among them, the channel module 22 is installed on the top surface of the pulse generator body 1. On the one hand, due to the large number of parts, the content of the glue medium forming the head 21 is small, so the shrinkage stress is small. On the other hand, the fixed structure of the channel module 22 is welded on the top of the body, which enhances the rigidity of the area where the channel module 22 is installed, so the area where the channel module 22 is installed will not be deformed. The top surface of the pulse generator body 1 is at least partially installed with a reinforcing structure 23 in the area where the channel module 22 is not installed. When the glue medium is filled into the head 21, the reinforcing structure 23 increases the number of parts in the area where the channel module 22 is not installed on the top surface of the pulse generator body 1. On the one hand, the content of the glue medium is reduced, and the deformation stress generated by the glue medium after curing is reduced; on the other hand, the reinforcing structure 23 is installed on the top surface of the pulse generator body 1, which effectively enhances the rigidity of the top surface of the pulse generator body 1, increases the difficulty of deformation of the top surface of the pulse generator body 1, and further prevents the glue medium from shrinking and deforming after curing.

[0056] In this embodiment, the material of the glue potting medium is a thermosetting polymer material, or the material of the glue potting medium is a mixture of a thermosetting polymer material and a silicone material. The thermosetting polymer material may be epoxy resin, phenolic resin, urea-formaldehyde resin, melamine resin, unsaturated polyester resin, epoxy resin, silicone resin, polyurethane, etc.

[0057] Preferably, a receiving cavity is formed between the reinforcing structure 23 and the pulse generator body 1, and the glue-filling medium is filled into the receiving cavity. The receiving cavity between the reinforcing structure 23 and the pulse generator body 1 is also filled with the glue-filling medium, which increases the contact area with the glue-filling medium. The side wall of the receiving cavity can prevent the glue-filling medium from deforming, thereby improving the adhesion of the bonding surface, further preventing the glue-filling medium from shrinking and deforming after curing, improving the top surface stiffness of the pulse generator body 1, and preventing the top surface of the pulse generator body 1 from deforming.

[0058] Before filling the glue filling medium, the reinforcing structural member 23 is first connected to the top surface of the pulse generator body 1 to prevent the reinforcing structural member 23 from shifting. In this embodiment, the reinforcing structural member 23 is welded, bonded, clamped or connected to the top surface of the pulse generator body 1 by fasteners, so that the reinforcing structural member 23 is connected to the top surface of the pulse generator body 1. Preferably, one of the reinforcing structural member 23 and the top surface of the pulse generator body 1 is provided with a positioning column, and the other is provided with a positioning groove, and the positioning column can be plugged into the positioning groove, thereby improving the installation accuracy of the reinforcing structural member 23.

[0059] In this embodiment, the reinforcing structural member 23 is a wave-shaped reinforcing sheet 2311, and a receiving cavity is formed between the wave crest of the reinforcing sheet 2311 and the top surface of the pulse generator body 1, so that a plurality of receiving cavities are formed between the reinforcing structural member 23 and the top surface of the pulse generator body 1, and openings are provided at both ends of the receiving cavity. When the glue is poured to form the head 21, the glue pouring medium can be filled into the receiving cavity through the opening. The wave trough of the reinforcing sheet 2311 can be welded or bonded to the top surface of the pulse generator body 1.

[0060] Preferably, the wave-shaped reinforcing sheet 2311 is provided with a first flow hole 2312. When the glue medium is filled, the glue medium can flow into the receiving cavity through the first flow hole 2312, thereby improving the fluidity of the glue medium, ensuring that the receiving cavity is filled with the glue medium, and improving the structural strength.

[0061] Embodiment 2

[0062] like Figure 4 As shown, this embodiment provides a pulse generator, and the structure of the pulse generator provided in this embodiment is basically the same as that of the embodiment 1, only the structure of the reinforcing structural member 23 is partially different, and this embodiment will no longer repeat the structure that is the same as that of the embodiment 1.

[0063] In this embodiment, the reinforcing structure 23 is mushroom-shaped, and the reinforcing structure 23 includes an umbrella-shaped portion 2321 and a rod portion 2322. One end of the rod portion 2322 is connected to the umbrella-shaped portion 2321, and the other end is connected to the top surface of the pulse generator body 1. Specifically, a welding connection method can be adopted. A accommodating cavity is formed between the umbrella-shaped portion 2321 and the top surface of the pulse generator body 1. After the accommodating cavity is filled with a potting medium, the umbrella-shaped portion 2321 can reduce the shrinkage stress applied to the pulse generator body 1 when the potting medium is solidified.

The troughs of the wavy strips 2331 are welded to the top surface of the pulse generator body 1, and a receiving cavity is formed between the crests of the wavy strips 2331 and the top surface of the pulse generator body 1. After the receiving cavity is filled with the glue potting medium, the wavy strips 2331 can reduce the shrinkage stress applied to the pulse generator body 1 when the glue potting medium is solidified.

[0067] Preferably, the wave strips 2331 may be cross-arranged to form a mesh structure, so as to further reduce the shrinkage stress applied to the pulse generator body 1 when the potting medium is solidified.

The connecting plate 2342 is connected to the top surface of the pulse generator body 1 at one end away from the flange 2341, and a receiving cavity is formed between the flange 2341 and the top surface of the pulse generator body 1. After the receiving cavity is filled with the glue medium, the flange 2341 and the connecting plate 2342 both increase the contact area with the glue medium, thereby reducing the shrinkage stress applied to the pulse generator body 1 when the glue medium is solidified.

[0071] Preferably, the flange 2341 is provided with a plurality of second flow holes 2343.

[0074] In this embodiment, the reinforcing structure 23 includes a connecting column 2351, which is installed on the top surface of the pulse generator body 1. The connecting column 2351 can be connected to the top surface of the pulse generator body 1 by welding, and the connecting column 2351 is provided with a plurality of fixed layers 2352 at intervals along the axial direction. After the accommodating cavity is filled with the potting medium, the gaps between the plurality of fixed layers 2352 are filled with the potting medium, which increases the contact area with the potting medium, thereby reducing the shrinkage stress applied to the pulse generator body 1 when the potting medium is solidified.
