Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an electrode connector. Background Art

[0002] In modern medicine, Neuroelectric Stimulation has become an effective means for treating various chronic pain and functional disorder diseases. This technology gently stimulates specific nerves through implanted electrodes to regulate nerve activities, relieve pain, and improve the quality of life of patients. The application scope of Neuroelectric Stimulation is extensive, including but not limited to spinal cord stimulation, peripheral nerve stimulation, and deep brain stimulation, etc.

[0003] Although Neuroelectric Stimulation has achieved remarkable results in clinical applications, there are still limitations in the design and application of existing electrode connectors. The electrode connector is a key component connecting the implanted electrode and the external stimulator, and its design and function directly affect the transmission efficiency and stability of electrical stimulation. Most of the electrode connectors on the market are of standardized design and can only be connected to electrodes with a specific diameter. This design limits the versatility and adaptability of the connector. Especially when facing electrodes with different diameter sizes, it is often necessary to customize or replace the connector, increasing the medical cost and operation complexity.

[0004] In addition, there are obvious inconveniences in the connection of existing electrode connectors for multi-diameter electrodes. Due to the lack of flexibility and compatibility, doctors need to prepare corresponding connectors according to the specific size of the electrode during the operation, which not only increases the preoperative preparation work but also may lead to the postponement or failure of the operation due to size mismatch. In addition, the connector with a single-diameter adaptation is difficult to meet the needs of personalized treatment in practical applications, restricting the wide application and development of Neuroelectric Stimulation.

[0005] In the scenario of multi-diameter electrode connection, the deficiencies of the existing technology are particularly obvious. Since different patients and different treatment requirements may require electrodes with different diameters, the connector with a single-diameter adaptation cannot meet the diverse clinical needs. This not only increases the consumption of medical resources but also affects the treatment effect and satisfaction of patients. Therefore, developing a universal electrode connector that can adapt to electrodes with multiple diameter sizes is of great significance for improving the flexibility, convenience, and clinical effect of Neuroelectric Stimulation. Summary of the Utility Model

[0009] A second electrode accommodating portion, a second positioning element and a second wire groove forming portion are provided inside the upper cover.

[0098] The assembly and use method of the electrode connector of the present utility model is as follows:

[0099] As Figure 7 shown, first, the angular elastic piece 1151 and the wire 3 are connected by soldering. The two angular elastic pieces 1151 are assembled and fixed to the elastic piece accommodating portion 1152 through the elastic piece positioning posts 1152, and the angular elastic pieces 1151 can be fixed by methods such as hot melting the second positioning element or gluing. The wire 3 is placed in the first wire groove forming portion 13, and the wire sleeve is placed in the first wire sleeve fixing groove forming portion 15 to position and fix the wire in the axial direction of the connector.

[0100] As Figures 8 - 9 shown, the first positioning element 12 and the second positioning element 22 are cooperated to achieve the positioning and fixing between the bottom cover 1 and the second half cover of the top cover 2.

[0103] As Figure 12 shown, after buckling the upper cover buckle 27 and the lower cover buckle 16, the upper cover 2 and the lower cover 1 are tightly fixed. At this time, as Figures 13 - 15 shown, the first electrode fixing groove forming part 113 and the second electrode fixing groove forming part 212 clamp the electrode by an interference fit so that it will not move axially. The second connecting ring pressing groove forming part 211 of the upper cover 2 presses the connecting ring at the proximal end of the stimulating electrode towards the angular shrapnel 1151, enabling reliable connection between the angular shrapnel 1151 and the connecting ring. The bending angle of the angular shrapnel 1151 can enable electrical conduction to be achieved when stimulating electrodes with different diameters are pressed down by the second connecting ring pressing groove forming part 211 of the upper cover.
