Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a stimulator electrode extension wire forming tool and a forming system, which are used for manufacturing a nystagmus stimulator. Background Art

[0002] In the device used for controlling and treating abnormal eye nystagmus, the implantable neurostimulator can be used to transmit electrical stimulation signals to the extraocular muscles, and inhibit or regulate the abnormal activity of the eye muscles through a specific electrical signal waveform, thereby inhibiting congenital eye nystagmus. Compared with traditional extraocular muscle shortening surgery, this method is safe and reversible, and has broad application prospects.

[0003] An implantable neurostimulator consists of three parts: a pulse generator, an extension lead, and a stimulation electrode. Among them, the extension lead plays the role of stimulating signal transmission, and needs to maintain stable mechanical and electrical properties during long-term implantation (usually up to several years to decades). Compared with other neuromodulatory devices (such as deep stimulators, vagus nerve stimulators, spinal cord stimulators, peripheral nerve stimulators, etc.) that have relatively fixed positions, the neuromuscular stimulation electrodes used for nystagmus are fixed on the extraocular muscles, and there will be a lot of activities every day. Along with the movement of the eyeballs, the electrodes will undergo stretching, compression, bending, twisting and other activities, which puts severe demands on the mechanical properties of the electrodes, and correspondingly, higher requirements are also placed on the extension leads.

[0004] The ISO14708.1 standard for implantable medical devices sets clear requirements for wire flexibility. However, this standard does not cover application scenarios with high activity intensity, such as extraocular muscles, nor does it exist a device for neural electrode fatigue testing for such scenarios.

[0042] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the various embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0043] The embodiments of the utility model provide a stimulator electrode extension wire forming tool and a forming system, which are used for manufacturing a nystagmus stimulator and can achieve accurate positioning and forming of the electrode extension wire.

[0044] According to an embodiment of one aspect of the utility model, a stimulator electrode extension wire forming tool is provided, which is used for manufacturing a nystagmus stimulator, comprising:

[0045] Base plate;

[0046] A lead screw mounted to the base plate and parallel to the base plate;

[0047] A first movable block and a second movable block are separated from each other and respectively meshed with the lead screw in opposite thread directions so as to move synchronously along the axial direction of the lead screw as the lead screw rotates and approach or move away from each other;

[0048] The first molding claw and the second molding claw are respectively mounted on the first movable block and the second movable block and respectively include a first molding surface and a second molding surface opposite to each other, the first molding surface and the second molding surface are corrugated and the shapes are matched so that the protrusions and recesses of the first molding surface are respectively aligned with the recesses and protrusions of the second molding surface, when the lead screw rotates to make the first movable block and the second movable block approach each other, a molding gap is formed between the first molding surface and the second molding surface for molding the electrode extension wire into a corrugated shape; wherein the first molding claw and the second molding claw can be separated relative to each other.

[0049] In this way, through the rotational movement of the lead screw, the first movable block and the second movable block engaged with the lead screw in opposite thread directions convert the rotational movement of the lead screw into their own linear movement, so that they can move synchronously along the lead screw and approach each other; when the first movable block and the second movable block approach to a predetermined distance, the corrugated molding surfaces of the first molding claw and the second molding claw installed thereon are opposite to each other, forming a channel that allows the electrode extension wire to be inserted and passed through; after the electrode extension wire is in place between the corrugated molding surfaces of the first molding claw and the second molding claw, the first movable block and the second movable block are driven by the rotation of the lead screw to further approach each other, so that the first molding surface and the second molding surface of the first molding claw and the second molding claw installed thereon are made to move synchronously along the lead screw. Correspondingly, the protrusion of the first molding surface is inserted into the recessed portion of the second molding surface, and the protrusion of the second molding surface is inserted into the recessed portion of the first molding surface, gradually forming a corrugated molding gap with undulating shapes between the first molding surface and the second molding surface, so that the protrusion of the first molding surface and the protrusion of the second molding surface can be utilized to contact the electrode extension wire to extrude the originally linear electrode extension wire inserted into the channel into a corrugated shape following the first molding surface and the second molding surface, that is, to be formed into a corrugated shape in the corrugated molding gap between the first molding surface and the second molding surface, thereby ensuring that the electrode extension wire is limited in the molding gap and accurately formed into the expected corrugated shape.

[0050] In addition, after completing the corrugation forming of the electrode extension wire, the first forming jaw and the second forming jaw can be separated from each other, thereby freeing up processing space to allow subsequent processing of the electrode extension wire that has completed the corrugation forming between the first forming jaw and the second forming jaw, without having to spend a long time rotating the lead screw to make the first movable block and the second movable block return to their original path to separate a sufficient distance from each other for subsequent processing of the electrode extension wire. This not only improves work efficiency, but also reduces the use loss of the lead screw and corresponding components.

[0051] It can be seen that the stimulator electrode extension wire forming tool provided by the embodiment of the utility model is used for the manufacture of the nystagmus stimulator, and can achieve accurate positioning and forming of the electrode extension wire.

[0052] The electrode extension wire used for the nystagmus stimulator is very thin and easily damaged, and it is difficult to form it into the expected curvature through manual operation. Through the stimulator electrode extension wire forming tooling described in this application, the precise movement and forming operation of the forming claws are achieved through the lead screw drive, which can not only significantly improve the forming efficiency, yield rate and consistency of the electrode extension wire, but also can accurately form the electrode extension wire to achieve the expected design size, shape and stretching effect.

[0053] It should be noted here that the "recessed portion" of the first molding claw and the second molding claw is relative to their "protruding portion", and the recessed portion may have a solid structure (for example, a recessed portion), or may simply be a preset space between adjacent protruding portions, thereby forming a molding gap of a predetermined shape (for example, a corrugated shape) between the first molding claw and the second molding claw.

[0054] It should also be noted that the shape matching of the first molding surface and the second molding surface refers to that the outer contours of the two relative molding surfaces are roughly the same or similar, so as to allow the protrusion of one molding surface to be inserted into the hollow portion of the other molding surface, so that the electrode extension wire located between the two can be formed following the contours of the first molding surface and the second molding surface. It should be emphasized here that the outer contours of the first molding surface and the second molding surface can be the same or similar (that is, not completely the same). On the other hand, the sizes of the first molding surface and the second molding surface can be the same or different, as long as the protrusion of one molding surface can be inserted into the hollow portion of the other molding surface, so that the electrode extension wire can be formed between the two molding surfaces as designed.

[0055] Optionally, in any embodiment, the protrusions of the first molding surface and the recesses of the second molding surface may have the same shape and size.

[0056] Optionally, in any embodiment, the protrusion of the second molding surface and the recess of the first molding surface may have the same shape and size.

[0057] Optionally, in any embodiment, the protrusion of the second molding surface is smaller in size than the hollow portion of the first molding surface, so that the protrusion can be inserted into the corresponding hollow portion to facilitate molding.

[0058] Optionally, in any embodiment, the protrusion of the first molding surface is smaller in size than the hollow portion of the second molding surface, so that the protrusion can be inserted into the corresponding hollow portion to facilitate molding.

[0059] Optionally, in any embodiment, the first molding surface and the second molding surface both have a shape of a smooth continuous curved surface.

[0060] Preferably, in any embodiment, the first molding surface and the second molding surface include a vertical portion extending perpendicular to the bottom plate. That is, the first molding surface and the second molding surface are opposite to each other with their curved side surfaces to press-form the electrode extension wire, and such curved side surfaces extend vertically upward perpendicular to the bottom plate as a whole, and present a corrugated curve shape for press-forming in the horizontal section. In this way, it is not only ensured that the straight electrode extension wire inserted into the channel is confined within the molding gap, but also allows multiple electrode extension wires to be inserted in parallel along different vertical positions, thereby performing molding operations on multiple electrode extension wires at the same time.

[0061] Optionally, in any embodiment, it may further include: a wire positioning device or structure, which is arranged outside the molding gap and includes a holding device or structure for holding the free end of the electrode extension wire in place. In this way, it can effectively ensure that the electrode extension wire inserted into the channel extends in a predetermined direction (for example, horizontal direction) to achieve molding in the molding gap, and also allow the electrode extension wire to adapt to the extrusion molding of the two molding claws during the molding process and produce adaptive movement, such as adaptive contraction of the free end of the electrode extension wire along the extension direction of the electrode extension wire.

[0062] Optionally, in any embodiment, the wire positioning device or structure includes: a clamping structure for clamping the free end of the electrode extension wire. In this way, it can be effectively ensured that the electrode extension wire inserted into the channel extends horizontally to be further molded in the molding gap. It should be understood here that the clamping is not fixed, but allows the electrode extension wire to adapt to the extrusion molding of the two molding claws to produce adaptive movement during the molding process to a certain extent, such as the adaptive contraction of the free end of the electrode extension wire along the extension direction of the electrode extension wire.

[0063] Optionally, in any embodiment, the lead-positioning device or structure includes: a support body for supporting the free end of the electrode extension lead and keeping it in place.

[0064] Optionally, in any embodiment, the support body of the wire positioning device or structure includes a positioning groove extending along the extension direction of the electrode extension wire.

[0065] Optionally, in any embodiment, the wire positioning device or structure includes: a positioning hole for supporting the free end of the electrode extension wire and keeping it in place. In this way, the free end of the electrode extension wire is inserted into the positioning hole aligned with it, thereby ensuring that the overall extension direction of the electrode extension wire meets the requirements.

[0066] Optionally, in any embodiment, the positioning hole of the wire positioning device or structure extends along the extension direction of the electrode extension wire. In this way, the free end of the electrode extension wire penetrates the positioning hole aligned with it and is positioned therein, thereby ensuring that the overall extension direction of the electrode extension wire meets the requirements.

[0067] Preferably, in any embodiment, a limiting structure for limiting the movement range of the first movable block and the second movable block is provided on the lead screw.

[0068] Optionally, in any embodiment, the limiting structure includes outer limiting structures respectively arranged on the outer sides of the first movable block and the second movable block, so as to prevent the first movable block and the second movable block from excessively moving outwards and disengaging from the threaded engagement with the lead screw or even disengaging from the lead screw.

[0069] Optionally, in any embodiment, the limiting structure includes inner limiting structures respectively arranged on the inner side of the first movable block and the inner side of the second movable block. In this way, the first movable block and the second movable block can be prevented from excessively moving inwards, causing the first forming claw and the second forming claw mounted thereon to be excessively close to each other, thereby affecting the formation of a precise forming gap between the two, or even contacting or colliding with each other, thereby causing damage to the components.

[0070] Optionally, in any embodiment, the limiting structure includes a retraction limiting structure respectively arranged on the outside of the first movable block and the second movable block. In this way, after the corrugation forming of the electrode extension wire is completed, the first movable block and the second movable block may be required to be retracted to the outside by a certain distance to facilitate providing a larger space between the first forming claw and the second forming claw for subsequent operations (such as inserting the next electrode extension wire or turning up the forming claw). The retraction limiting structure can accurately limit the retraction distance of the first movable block and the second movable block, which is sufficient to ensure sufficient retraction and avoid excessive retraction that affects work efficiency.

[0071] Optionally, in any embodiment, the retraction limit structure is a movable structure that can switch between a limit position and an avoidance position. In this way, the retraction limit structure can be in the avoidance position when not in use to avoid interfering with the operation of the first movable block and the second movable block.

[0072] Preferably, in any embodiment, a slideway extending parallel to the lead screw is provided on the bottom plate; the first movable block and the second movable block move along the slideway under the drive of the lead screw. In this way, it can be ensured that the first movable block and the second movable block move linearly along the slideway according to a predetermined route under the rotation drive of the lead screw.

[0073] Preferably, in any embodiment, the slideway comprises a slide groove. In this way, under the rotational drive of the lead screw, the first movable block and the second movable block can be restricted in the slide groove to perform linear motion.

[0074] Preferably, in any embodiment, the slideway comprises a slide rail having linear ridges. Thus, under the rotational drive of the lead screw, the first movable block and the second movable block can be restricted to perform linear motion along the ridges of the slide rail.

[0075] Optionally, in any embodiment, the slide rail comprises: a pair of parallel linear ridges. In this way, the first movable block and the second movable block slide on the pair of ridges (slide rails) to have better movement stability.

[0076] It should be understood that the slide groove and the slide rail can be used alone or in combination as required.

[0077] Preferably, in any embodiment, the first forming jaw and the second forming jaw can be turned upward away from the bottom plate to separate relative to each other. In this way, the two forming jaws can be turned upward (i.e. turned upward away from the bottom plate and turned outward), thereby separating or opening relative to each other.

[0078] Preferably, in any embodiment, the first forming jaw and the second forming jaw are respectively mounted on the first movable block and the second movable block via a first pivot and a second pivot extending horizontally perpendicular to the lead screw, and can be flipped upward away from the base plate via the first pivot and the second pivot to separate relative to each other (for example, flipped to the left and right sides respectively to open).

[0079] Preferably, in any embodiment,

[0080] The protrusion of the first forming claw comprises: a first smooth cylinder extending downward from the lower surface of the first forming claw or extending upward from the upper surface of the first forming claw and contacting with the electrode extension wire to be formed;

[0081] The protrusion of the second forming claw comprises: a second smooth cylinder extending downward from the lower surface of the second forming claw or extending upward from the upper surface of the second forming claw and contacting with the electrode extension wire to be formed;

[0082] The first smooth cylinder and the second smooth cylinder are staggered to form the corrugated forming gap between the first smooth cylinder and the second smooth cylinder.

[0083] In this way, the electrode extension wire between them can be pressed and formed by the first smooth cylinder (for example, there can be multiple) and the second smooth cylinder (for example, there can be multiple) that are staggered and aligned with each other. During the forming process, the first smooth cylinder is aligned with the position between the two adjacent second smooth cylinders opposite to it (corresponding to the second recessed part or the relatively concave forming space), and the second smooth cylinder is also aligned with the position between the two adjacent first smooth cylinders opposite to it (corresponding to the first recessed part or the relatively concave forming space), which is the so-called "staggered distribution" or "staggered alignment". It should also be noted that the first smooth cylinder and the second smooth cylinder can extend upward from the upper surface of the main body of the first molding claw and the second molding claw (for example, vertically extend upward), and can also extend downward from the lower surface of the main body of the first molding claw and the second molding claw (for example, vertically extend downward), and a suitable structure can be selected according to needs.

[0084] Through such a structure, the posture of the electrode extension wire inserted between the two forming claws can be conveniently adjusted when necessary. Since the recessed portion described in this embodiment is a non-solid concave space, the posture of the electrode extension wire can be adjusted using tools through the space distributed around the first smooth cylinder and the second smooth cylinder without being blocked or interfered by the solid structure.

[0085] For example, in Figure 2 In the illustrated embodiment, first and second smooth cylinders 522 extending downward (eg, extending vertically downward) from lower surfaces of the main bodies of the first and second molding jaws 510 and 520 are visible.

[0086] Optionally, in any embodiment, the first smooth cylinder and / or the second smooth cylinder at least partially includes a cylindrical portion.

[0087] Preferably, in any embodiment,

[0088] A first spring structure is provided on the first moving block, and the first forming claw is mounted to the first moving block through the first spring structure;

[0089] The second movable block is provided with a second spring structure, and the second forming claw is mounted to the second movable block through the second spring structure.

[0090] In this way, the first forming claw and the second forming claw can be adjusted in posture (such as height adjustment or tilt angle adjustment) by the first spring structure and the second spring structure, so that the two forming claws are precisely positioned and cooperated to press and form the electrode extension wire.

[0091] Optionally, in any embodiment, the first spring structure includes more than three springs extending in the vertical direction, and the second spring structure includes more than three springs extending in the vertical direction. In this way, by providing three or more springs for both the first spring structure and the second spring structure, the angle adjustment of the first forming claw and the second forming claw can be achieved more stably and reliably.

[0092] Optionally, in any embodiment, the upper surface of the first movable block is provided with a slope located outside the first pivot and facing the forming gap. In this way, after the first forming jaw is turned upward by the first pivot, it can be reliably placed on the slope to avoid the forming jaw from turning back and falling due to unexpected circumstances (such as external force collision or vibration).

[0093] Optionally, in any embodiment, the upper surface of the second movable block is provided with a slope located outside the second pivot and facing the forming gap. In this way, after the second forming jaw is turned upward by the second pivot, it can be securely placed on the slope to avoid the forming jaw from turning back and falling due to unexpected circumstances (such as external force collision or vibration).
