Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to contact brackets, directional electrodes and stimulation systems. Background Technology

[0002] As a key component for electrical stimulation or electrical signal transmission, the manufacturing process of directional electrodes is often complex and consumes a lot of materials.

[0003] In traditional methods, the stimulation patches of the directional electrode are prefabricated. During installation, the connecting material is removed by grinding or other methods, so that the stimulation patches can be attached to the designated parts of the electrode body in pieces, ensuring that the distribution of stimulation patches on the electrode body meets the treatment requirements.

[0004] However, the material removed by this grinding method is directly wasted, and space needs to be made for the installation of the guide wire when installing the stimulating pad, which makes the operation of this installation method more difficult, thus increasing the manufacturing difficulty and cost of the electrode in this direction. Utility Model Content

[0005] The purpose of this invention is to provide a contact support, a directional electrode, and a stimulation system, which solves the problem that in the prior art, the stimulation pad of the directional electrode needs to be ground before installation, which not only wastes materials, but also requires consideration of the wiring of the guide wire during installation, thus increasing the difficulty of installation, and consequently increasing the manufacturing difficulty and cost of the directional electrode.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] In a first aspect, this utility model provides a contact bracket, which includes:

[0008] The main body is provided with multiple wiring grooves spaced around its circumference, the wiring grooves being used for the guide wires to pass through;

[0009] The mounting assembly is disposed on the body and has a plurality of insulatingly separated mounting slots, the mounting slots being used to mount stimulation contacts.

[0010] Optionally, the stimulation contact is a stimulation pad, the mounting slot includes a first mounting slot for mounting the stimulation pad, and the mounting assembly includes:

[0011] A plurality of first spacers are circumferentially spaced around the main body, and the first spacers extend along a first direction;

[0012] Multiple second spacers are spaced apart along the axial direction of the main body. The second spacers extend along a second direction, which intersects the first direction. The first spacers and the second spacers enclose and form multiple insulatingly separated first mounting grooves, which are mutually insulatingly separated.

[0013] Optionally, at least four sets of the mounting slots are distributed at intervals along the axial direction of the body, and each set of the mounting slots includes at least three of the first mounting slots.

[0014] Optionally, the first direction is the axial direction of the body, and the second direction is the circumferential direction of the body, such that the plurality of the first mounting slots are distributed along the circumferential and axial directions of the body.

[0015] Optionally, the stimulation contact is a stimulation ring, and the mounting groove includes a second mounting groove for mounting the stimulation ring, wherein the end face of the second spacer and the outer side wall of the body form the second mounting groove.

[0016] Optionally, at least four sets of mounting slots are distributed at intervals along the axial direction of the main body, wherein the first and last sets of mounting slots are the second mounting slots, and the other sets of mounting slots between the first and last sets of the second mounting slots each include at least three of the first mounting slots.

[0017] Optionally, each of the wiring slots corresponds to a plurality of the mounting slots and communicates with the mounting slots.

[0018] Optionally, the stimulation contact is fixed in the mounting groove by potting.

[0019] Secondly, this utility model also provides a directional electrode, which includes:

[0020] The stimulation segment includes a stimulation contact and a contact support as described in any one of the first aspects, wherein the stimulation contact is disposed of the contact support;

[0021] A guide wire is inserted into the wiring groove of the contact bracket.

[0022] Thirdly, this utility model also provides a stimulation system, which includes:

[0023] Stimulator;

[0024] As described in the second aspect, the directional electrode has one end implanted in the patient's body and the other end electrically connected to the stimulator.

[0025] Optionally, the stimulation system further includes:

[0026] An extension wire is provided, through which the stimulator is electrically connected to the directional electrode.

[0027] The beneficial effects of this utility model are:

[0028] Firstly, by pre-setting wiring grooves on the contact bracket, space is provided for the guide wire to pass through, ensuring that the guide wire can be smoothly arranged on the main body. Furthermore, by pre-setting mounting grooves on the mounting components, the stimulating pad can be manufactured directly according to the shape of the mounting groove during manufacturing, and then directly installed into the mounting groove after manufacturing. Therefore, when installing the stimulating pad, this contact bracket not only eliminates the need for grinding the stimulating contacts, thus reducing the waste of precious metal materials such as platinum and iridium used in manufacturing the stimulating contacts, but also eliminates the need to consider the placement of the guide wire during installation, effectively reducing the installation difficulty. This, in turn, helps to reduce the manufacturing difficulty and cost of the contact bracket, thereby reducing the manufacturing difficulty and cost of the directional electrode using this contact bracket.

[0029] Secondly, during the manufacturing of this directional electrode, the wiring groove is pre-set on the contact bracket, and the guide wire can be directly inserted into the wiring groove during installation. During the manufacturing of this contact bracket, the stimulation contact no longer needs to be ground, thus avoiding material waste, and there is no need to consider the installation position of the guide wire. The stimulation contact can be directly installed in the installation groove, which helps to reduce the manufacturing difficulty and cost of this directional electrode.

[0030] Thirdly, when the stimulation system is in use, as the manufacturing difficulty and cost of the contact bracket decrease, the manufacturing difficulty and cost of the directional electrode can also be reduced, thus reducing the overall manufacturing difficulty and cost of the stimulation system, thereby improving both the yield and cost-effectiveness of the stimulation system.

[0044] This utility model discloses a contact support, a directional electrode, and a stimulation system.

[0045] Example 1

[0046] Reference Figure 1 and Figure 2 The contact support includes a main body 1 and a mounting assembly 2. The main body 1 is provided with a plurality of axially extending wiring grooves 11 at intervals, the wiring grooves 11 being used for the guide wire 6 to pass through; the mounting assembly 2 is disposed on the main body 1 and has a plurality of mounting grooves, the mounting grooves being insulated from each other, the mounting grooves being used for mounting stimulation contacts.

[0047] Specifically, the main body 1 is cylindrical, with multiple wiring grooves 11 extending axially through its surface to accommodate guide wires 6. In this embodiment, the multiple wiring grooves 11 are evenly spaced around the circumference of the main body 1. An installation assembly 2 is provided on the outer wall of the main body 1. The installation assembly 2 forms multiple installation grooves according to actual treatment needs, with adjacent installation grooves insulated from each other. Each installation groove can accommodate a stimulation patch 3 or a stimulation ring as a stimulation contact, ensuring that adjacent stimulation contacts are insulated from each other. The stimulation contacts can be fixed in the installation groove by adhesive bonding or other methods, which are not limited in this invention. The specific shape and layout of the installation grooves are also not limited in this invention.

[0048] By pre-setting a wiring groove 11 on the contact bracket, space is provided for the guide wire 6 to pass through, ensuring that the guide wire 6 can be smoothly arranged on the main body 1. Furthermore, by pre-setting an installation groove in the mounting component 2, the stimulating pad 3 can be manufactured directly according to the shape of the installation groove during manufacturing, and then directly installed in the installation groove after manufacturing. Therefore, when installing the stimulating pad 3, this contact bracket not only eliminates the need for grinding the stimulating contacts, thus reducing the waste of precious metal materials such as platinum and iridium used in manufacturing the stimulating contacts, but also eliminates the need to consider the placement of the guide wire 6 during installation, effectively reducing the installation difficulty. This, in turn, helps to reduce the manufacturing difficulty and cost of the contact bracket, thereby reducing the manufacturing difficulty and cost of the directional electrode using this contact bracket.

[0049] Optionally, the stimulation contact is a stimulation patch 3, and the mounting groove includes a first mounting groove 21 for mounting the stimulation patch 3. The mounting assembly 2 includes a plurality of first spacers 22 and a plurality of second spacers 23. The plurality of first spacers 22 are circumferentially spaced around the main body 1 and extend along a first direction X. The plurality of second spacers 23 are axially spaced along the main body 1 and extend along a second direction Y. The first direction X and the second direction Y intersect. The first spacers 22 and the second spacers 23 enclose each other to form a plurality of first mounting grooves 21, and the first mounting grooves 21 are mutually insulated and separated.

[0050] Specifically, the first partition 22 and the second partition 23 are both strip-shaped and are arranged alternately on the main body 1, so that the sidewalls of the first partition 22 and the sidewalls of the second partition 23 enclose and form a plurality of first mounting grooves 21. The specific arrangement of the first mounting grooves 21 can be designed according to the actual treatment needs, and only the intersection angle of the first direction X and the second direction Y needs to be adjusted accordingly.

[0051] By providing the first spacer 22 and the second spacer 23, a corresponding first mounting groove 21 can be formed on the surface of the main body 1 to serve as the mounting space for the stimulating patch 3. Therefore, the stimulating patch 3 can be prefabricated according to the layout and shape of the first mounting groove 21 during manufacturing, thereby reducing the possibility of needing to grind the stimulating patch 3 and minimizing the waste of precious metals. Furthermore, the layout and shape of the first mounting groove 21 can be adjusted according to treatment needs, allowing the stimulating patch 3 to be precisely fixed at a designated position on the main body 1, further reducing the difficulty of installing the stimulating patch 3.

[0052] Optionally, at least four sets of mounting slots are distributed at intervals along the axial direction of the main body 1, and each set of mounting slots includes at least three first mounting slots 21.

[0053] Specifically, at least four sets of mounting slots are equally spaced along the circumference of the main body 1, and the three first mounting slots 21 in each set of mounting slots are equally spaced around each other, so that the contact bracket forms 12 stimulation contacts in a 3-3-3-3 pattern.

[0054] Optionally, the first direction X is the axial direction of the main body 1, and the second direction Y is the circumferential direction of the main body 1, so that the plurality of first mounting grooves 21 are distributed along the circumferential and axial directions of the main body 1.

[0055] Specifically, the first interval 22 and the second interval 23 intersect perpendicularly, making the shape of the first mounting groove 21 regular, which helps to further reduce the manufacturing difficulty of the stimulating piece 3 and facilitates the quick positioning and installation of the stimulating piece 3 into the corresponding first mounting groove 21. The distribution of the multiple first mounting grooves 21 can be evenly distributed at equal intervals or unevenly distributed. The specific design can be made according to the actual production needs, and this application does not limit it.

[0056] Optionally, each wiring slot 11 corresponds to multiple mounting slots and is connected to the mounting slots.

[0057] Specifically, a wiring groove 11 is formed by recessing the bottom wall of the mounting groove. The wiring groove 11 extends through the circumference of the main body 1, so that the wiring groove 11 is connected to the mounting groove and the wiring groove 11 overlaps with the mounting groove in the radial direction of the main body 1. This facilitates the opening of the wiring groove 11 on the main body 1 and also provides a reference for the opening of the mounting groove, thereby further reducing the processing difficulty.

[0058] Alternatively, the stimulation contact can be fixed in the mounting groove by potting.

[0059] Specifically, after the stimulation contact is installed into the mounting groove, it is fixed in the groove by injecting adhesive. Epoxy can also be injected to increase the adhesion of the stimulation contact. Furthermore, stepped or raised snap-fit ​​structures can be added to the stimulation contact to increase the contact area with the adhesive, thereby improving the bonding strength of the stimulation contact.

[0060] Reference Figure 3 The directional electrode includes stimulation segment 5 and guidewire 6 (see reference). Figure 1 The stimulation segment 5 includes a stimulation contact and a contact support as described in the above embodiment. The stimulation contact is provided with a contact support. The guide wire 6 passes through the wiring groove 11 of the contact support.

[0061] During the manufacturing of this directional electrode, the wiring groove 11 is pre-set on the contact bracket, and the guide wire 6 can be directly inserted into the wiring groove 11 during installation. During the manufacturing of this contact bracket, the stimulation contact no longer needs to be ground, thus avoiding material waste, and there is no need to consider the installation position of the guide wire 6. The stimulation contact can be directly installed in the mounting groove, which helps to reduce the manufacturing difficulty and cost of this directional electrode.

[0062] The stimulation system includes a directional electrode, a stimulator, and an extension wire as described in the above embodiments; one end of the directional electrode is implanted in the patient's body, and the other end is electrically connected to the stimulator or electrically connected to the stimulator via the extension wire.

[0063] When this stimulation system is in use, as the manufacturing difficulty and cost of the contact bracket are reduced, the manufacturing difficulty and cost of the directional electrode can also be reduced, thus reducing the overall manufacturing difficulty and cost of the stimulation system, thereby improving both the yield and cost-effectiveness of the stimulation system.

[0064] Example 2

[0065] Based on Example 1, the difference between this example and Example 1 lies in the different structure of the mounting slot.

[0066] Reference Figure 6 and Figure 7 Optionally, the stimulation contact is a stimulation ring 4, and the mounting groove includes a second mounting groove 24 for mounting the stimulation ring 4. The end face of the second spacer 23 forms the second mounting groove 24 with the outer side wall of the body 1.

[0067] Specifically, multiple second spacers 23 are spaced apart, and first spacers 22 are provided between the multiple second spacers 23 to form a first mounting groove 21. A second mounting groove 24 is formed between the end face of the second spacer 23 away from the first spacer 22 and the outer side wall of the main body 1. That is, the first mounting groove 21 and the second mounting groove 24 are insulated and separated by the second spacers 23, and the first spacers 22 do not extend into the first limiting groove. A stimulation ring 4 can be provided in the second mounting groove 24 as a stimulation contact.

[0068] By forming the second mounting groove 24, the stimulation contact layout on the main body 1 can adopt either a stimulation ring 4 or a stimulation sheet 3. Moreover, the stimulation ring 4 is directly positioned and installed in the second mounting groove 24, which makes the installation process simple and the positioning accuracy high.

[0069] Optionally, at least four sets of mounting slots are distributed at intervals along the axial direction of the main body 1, wherein the first and last sets of mounting slots are second mounting slots 24, and the other sets of mounting slots between the first and last sets of second mounting slots 24 each include at least three first mounting slots 21.

[0070] Specifically, two second mounting slots 24 are spaced apart on the main body 1, and a stimulation ring 4 is provided in each second mounting slot 24. Two sets of mounting slots are provided between the two second mounting slots 24, and each set of mounting slots includes three second mounting slots 24. A stimulation piece 3 is provided in each first mounting slot 21, so that the contact bracket forms a total of 8 contacts in a 1-3-3-1 configuration.

[0071] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
