Connectors and neurostimulators

Abstract

This application relates to a connector and a neurostimulator. The connector includes: a mounting base with a receiving cavity; a connecting member disposed on the mounting base; a crimping member slidably disposed on the mounting base along a first direction; a sliding member slidably disposed on the mounting base along a second direction, the second direction forming an angle with the first direction; and a conductive elastic member electrically connected to the connecting member, located on the sliding path of the crimping member and, in its natural state, outside the receiving cavity. The crimping member, the conductive elastic member, and the receiving cavity are sequentially distributed along the first direction. The sliding member, while sliding along the positive direction of the second direction, pushes the crimping member closer to the receiving cavity along the first direction. The crimping member, while moving closer to the receiving cavity along the first direction, causes the conductive elastic member to deform towards the receiving cavity, thereby crimping the electrode to the cavity wall. When the conductive elastic member is deformed towards the receiving cavity, the sliding member is locked to the mounting base. This connector can reliably connect to the electrode.

Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to connectors and neurostimulators. Background Technology

[0002] In existing technologies, overactive bladder (OAB) is a syndrome characterized by urinary urgency, often accompanied by urinary frequency, nocturia, and urge incontinence, severely impacting quality of life. Treatment methods for OAB typically include behavioral therapy, pharmacological therapy, and surgical intervention. Behavioral therapy is only suitable for patients with mild symptoms; pharmacological therapy, as a second-line treatment, often suffers from poor clinical outcomes and patient compliance due to ineffectiveness and adverse reactions such as dry mouth, constipation, and visual impairment; surgical treatment mainly includes botulinum toxin injections and nerve stimulation. Botulinum toxin injections are extremely expensive, therefore, the academic community hopes to treat refractory OAB through nerve stimulation. Tibial nerve electrical stimulation has the advantages of good therapeutic effect and minimal invasiveness, and has gradually become a popular nerve stimulation method for treating overactive bladder (OAB) in recent years.

[0003] A neurostimulator is a medical device used to implement the aforementioned nerve stimulation methods. Specifically, a neurostimulator includes a pulse generator and electrodes. The doctor applies the pulse generator to the skin surface and implants one end of the electrode near the tibial nerve in the leg. The electrode is then electrically connected to the pulse generator via a connector. During operation, the pulse generator produces electrical signals, which are transmitted sequentially through the connector and the electrode to the tibial nerve, thereby applying electrical stimulation to the patient's tibial nerve. However, in existing connectors, the electrode and connector are electrically connected via a plug-and-play method. Since the electrodes are very thin, this results in poor reliability of the connection between the electrode and the connector. During surgery, the electrode easily detaches from the connector, causing inconvenience for the surgeon. Utility Model Content

[0004] Therefore, it is necessary to provide a connector and a neurostimulator to address the above problems.

[0005] To address the above problems, this application provides the following technical solution:

[0006] A connector comprising:

[0007] Mounting base, wherein the mounting base is provided with a receiving cavity for accommodating electrodes;

[0008] A connector for electrically connecting a pulse generator is provided on the mounting base;

[0009] The crimping member is slidably disposed on the mounting base along a first direction;

[0010] A sliding member, slidably disposed on the mounting base along a second direction, wherein the second direction forms an angle with the first direction; and

[0011] The conductive elastic element electrically connected to the connector is located on the sliding path of the crimping member and is located outside the accommodating cavity in its natural state; the crimping member, the conductive elastic element, and the accommodating cavity are distributed sequentially along the first direction;

[0012] The slider can push the crimping member closer to the receiving cavity along the first direction as it slides along the positive direction of the second direction. The crimping member can deform the conductive elastic member toward the receiving cavity as it moves toward the receiving cavity along the first direction, so as to press the electrode onto the cavity wall of the receiving cavity. When the conductive elastic member is deformed toward the receiving cavity, the slider is locked to the mounting base.

[0013] This connector has at least the following beneficial effects:

[0014] When it is necessary to electrically connect the electrode to the pulse generator, the electrode is inserted into the receiving cavity. Then, the sliding member slides along the positive direction of the second direction, thereby pushing the pressing member closer to the receiving cavity along the first direction. This causes the conductive elastic element to deform towards the receiving cavity, pressing the electrode against the cavity wall. Simultaneously, the connector is electrically connected to the pulse generator. In this way, the pulse generator and the electrode are electrically connected through the connector and the conductive elastic element. Furthermore, the conductive elastic element pressing the electrode against the cavity wall ensures the reliability of the connection between the electrode and the connector. Thus, during surgery, the electrode and connector remain reliably connected and will not loosen, facilitating the surgeon's operation.

[0015] In one embodiment, the first direction is perpendicular to the second direction.

[0016] This design has two advantages. First, it increases the positive pressure between the slider and the mounting base, which in turn increases the friction between them and helps lock the slider in place. Second, the movement of the pressing component and the movement of the slider are completely decoupled in space, which helps avoid motion interference.

[0017] In one embodiment, the crimping member includes a push-receiving portion and a crimping head. The crimping head protrudes from the side of the push-receiving portion facing the conductive elastic element and is disposed directly opposite the conductive elastic element along the first direction. The side of the push-receiving portion away from the conductive elastic element has a transmission surface. The transmission surface has a first end and a second end. In the second direction, the first end is relatively closer to the negative direction of the second direction, and the second end is relatively closer to the positive direction of the second direction. From the first end to the second end, the transmission surface gradually moves away from the receiving cavity. The transmission surface is located on the sliding path of the slider.

[0018] With this configuration, as the slider slides along the positive direction of the second direction, it will push the pressing member along the first direction to approach the accommodating cavity through the transmission surface. The pressing member will then push the conductive elastic member toward the accommodating cavity to deform, so that the conductive elastic member presses the electrode onto the cavity wall of the accommodating cavity.

[0019] In one embodiment, the side of the pushed portion away from the conductive elastic element also has a pressing surface, which extends from the second end along the positive direction of the second direction.

[0020] With this configuration, the sliding member can slide along the transmission surface to the pressing surface, and once it reaches the pressing surface, it can no longer push the pressing member towards the receiving cavity along the first direction. This helps to prevent excessive deformation of the conductive elastic element and protects the conductive elastic element and the electrode.

[0021] In one embodiment, the press-fitting component is a plastic part.

[0022] This design has two advantages. First, the deformation of the plastic part allows for better pressing of the conductive elastic element against the electrode, and also helps to better press the electrode against the cavity wall. Second, it helps prevent wear on the conductive elastic element caused by the pressing component, thus protecting the conductive elastic element.

[0023] In one embodiment, one end of the conductive elastic element is fixedly connected to the mounting base, while the other end is suspended in the air.

[0024] This configuration facilitates the deformation of the conductive elastic element. As the pressing component approaches the receiving cavity along the first direction, the conductive elastic element is more likely to deform toward the receiving cavity.

[0025] In one embodiment, the projection of the conductive elastic element along the first direction intersects the projection of the accommodating cavity along the first direction, and the suspended end of the conductive elastic element is positioned directly opposite the crimping joint along the first direction.

[0026] This configuration allows the conductive elastic element to stably press the electrode against the cavity wall of the accommodating cavity.

[0027] In one embodiment, the mounting base is further provided with a limiting channel, which extends along the first direction to the receiving cavity, and one suspended end of the conductive elastic element is located in the limiting channel; along the second direction, the maximum gap between the crimp connector and the limiting channel is D1; ​​the dimension of the conductive elastic element in the second direction is D2, and D1 and D2 satisfy: D1 < D2.

[0028] With this configuration, the conductive elastic element is confined by the limiting channel and the pressure joint on the sliding path of the pressure joint, which ensures that the conductive elastic element deforms toward the receiving cavity under the action of the pressure joint.

[0029] In one embodiment, the accommodating cavity is cylindrical, and the axis of the accommodating cavity is perpendicular to the first direction.

[0030] This configuration allows the conductive elastic element to stably press the electrode against the cavity wall of the accommodating cavity.

[0031] This application also provides a neurostimulator, which includes:

[0032] electrode;

[0033] Pulse generator; and

[0034] In the aforementioned connector, the connecting element is electrically connected to the pulse generator. When the conductive elastic element deforms toward the accommodating cavity, the conductive elastic element presses the electrode against the cavity wall of the accommodating cavity.

[0035] This neurostimulator has at least the following beneficial effects:

[0036] In this neurostimulator, when it is necessary to electrically connect the electrode to the pulse generator, the electrode is inserted into the receiving cavity. Then, the slider slides along the positive direction of the second direction, thereby pushing the pressing member closer to the receiving cavity along the first direction. This causes the conductive elastic element to deform towards the receiving cavity, pressing the electrode against the cavity wall. Simultaneously, the connector is electrically connected to the pulse generator. In this way, the pulse generator and the electrode are electrically connected through the connector and the conductive elastic element. Furthermore, the conductive elastic element pressing the electrode against the cavity wall ensures the reliability of the connection between the electrode and the connector. Thus, during surgery, the electrode and connector remain reliably connected and will not loosen, facilitating the surgeon's operation. Attached Figure Description

[0054] See Figures 1 to 9 This application first provides a connector 1 for electrically connecting an electrode 2 and a pulse generator together; it includes a mounting base 11, a connecting member 12, a crimping member 13, a sliding member 14, and a conductive elastic member 15. The mounting base 11 has a receiving cavity 111 for receiving the electrode 2. The connecting member 12 is disposed on the mounting base 11 for electrically connecting to the pulse generator. The crimping member 13 is slidably disposed on the mounting base 11 along a first direction, and the sliding member 14 is slidably disposed on the mounting base 11 along a second direction, the second direction forming an angle with the first direction. The conductive elastic member 15 is electrically connected to the connecting member 12, located on the sliding path of the crimping member 13, and in its natural state, located outside the receiving cavity 111. The crimping member 13, the conductive elastic member 15, and the receiving cavity 111 are distributed sequentially along the first direction.

[0055] The slider 14 can push the crimping member 13 towards the receiving cavity 111 along the first direction as it slides along the positive direction of the second direction. The crimping member 13 can cause the conductive elastic member 15 to deform towards the receiving cavity 111 as it moves towards the receiving cavity 111 along the first direction, thereby crimping the electrode 2 to the cavity wall of the receiving cavity 111. When the conductive elastic member 15 is deformed towards the receiving cavity 111, the slider 14 is locked to the mounting base 11.

[0056] When it is necessary to electrically connect electrode 2 to the pulse generator, electrode 2 is inserted into the receiving cavity 111. Then, the sliding member 14 slides along the positive direction of the second direction, thereby pushing the pressing member 13 closer to the receiving cavity 111 along the first direction. This causes the conductive elastic member 15 to deform towards the receiving cavity 111, so that the conductive elastic member 15 presses the electrode 2 against the cavity wall of the receiving cavity 111. Meanwhile, the connector 12 is electrically connected to the pulse generator. In this way, the pulse generator and electrode 2 are electrically connected through the connector 12 and the conductive elastic member 15. Moreover, the conductive elastic member 15 presses the electrode 2 against the cavity wall of the receiving cavity 111, which ensures the reliability of the connection between electrode 2 and connector 1. Thus, during the operation, electrode 2 and connector 1 are always reliably connected and will not loosen, facilitating the surgeon's operation.

[0057] When it is necessary to remove electrode 2 from connector 1, slide the slider 14 along the negative direction of the second direction until the conductive elastic element 15 returns to its natural state, and then pull out electrode 2.

[0058] Preferred options, please refer to Figure 2 The first direction is perpendicular to the second direction. On the one hand, this helps to increase the positive pressure between the slider 14 and the mounting base 11, which helps to increase the friction between the slider 14 and the mounting base 11, and helps to lock the slider 14 to the mounting base 11. On the other hand, the movement of the pressing member 13 and the movement of the slider 14 are completely decoupled in space, which helps to avoid motion interference.

[0059] In some embodiments, the mounting base 11 is provided with a slide rail that extends linearly along a second direction. As the slide rail extends along the positive direction of the second direction, it gradually approaches the receiving cavity 111, and the sliding member 14 slides in engagement with the slide rail. The side of the pressing member 13 away from the conductive elastic member 15 is planar and is arranged parallel to the receiving cavity 111. Thus, by sliding the sliding member 14 along the positive direction of the second direction, the pressing member 13 can be pushed towards the receiving cavity 111 along the first direction, causing the conductive elastic member 15 to deform towards the receiving cavity 111, thereby pressing the electrode 2 against the cavity wall of the receiving cavity 111. In these embodiments, the coefficients of friction of the slider 14 and the mounting base 11 are both relatively large. When the conductive elastic element 15 is deformed toward the receiving cavity 111, due to the reaction force of the conductive elastic element 15 and the reaction force of the pressing element 13, the pressing element 13 presses the slider 14 onto the mounting base 11. The positive pressure between the slider 14 and the mounting base 11 is relatively large, and the friction between the slider 14 and the mounting base 11 is relatively large, so that the slider 14 cannot slide relative to the mounting base 11. Thus, the slider 14 is locked to the mounting base 11.

[0060] See Figure 2 , Figure 3 and Figure 8In some embodiments, the crimping member 13 includes a push-receiving portion 131 and a crimping head 132. The crimping head 132 protrudes from the side of the push-receiving portion 131 facing the conductive elastic member 15 and is directly opposite the conductive elastic member 15 along a first direction. The side of the push-receiving portion 131 away from the conductive elastic member 15 has a transmission surface 1311. The transmission surface 1311 has a first end 13111 and a second end 13112. In the second direction, the first end 13111 is relatively closer to the negative direction of the second direction, and the second end 13112 is relatively closer to the positive direction of the second direction. From the first end 13111 to the second end 13112, the transmission surface 1311 gradually moves away from the receiving cavity 111. The transmission surface 1311 is located on the sliding path of the slider 14. In this way, as the slider 14 slides along the positive direction of the second direction, it will push the crimping member 13 along the first direction to approach the receiving cavity 111 through the transmission surface 1311. The crimping member 132 will then push the conductive elastic member 15 toward the receiving cavity 111 to deform, so that the conductive elastic member 15 will press the electrode 2 against the cavity wall of the receiving cavity 111.

[0061] Combination Figure 2 and Figure 8 In some embodiments, the second direction is a left-right direction, wherein the rightward direction is the positive direction of the second direction. In the second direction, the first end 13111 is relatively to the left, and the second end 13112 is relatively to the right.

[0062] See Figure 2 and Figure 8 The side of the pushed portion 131 away from the conductive elastic element 15 also has a pressing surface 1312, which extends from the second end 13112 along the positive direction of the second direction. In this way, the sliding member 14 can slide along the transmission surface 1311 to the pressing surface 1312, and after sliding to the pressing surface 1312, it can no longer push the pressing member 13 towards the receiving cavity 111 along the first direction. This helps to prevent excessive deformation of the conductive elastic element 15 and helps to protect the conductive elastic element 15 and the electrode 2.

[0063] Preferred options, please refer to Figure 2 , Figure 3 , Figure 8 and Figure 9 The side of the sliding member 14 facing the pressing member 13 is conformally adapted to the side of the pushed part 131 away from the conductive elastic member 15.

[0064] Preferably, the pressing member 13 is a plastic part. On the one hand, the deformation effect of the plastic part is beneficial for better pressing the conductive elastic member 15 onto the electrode 2, and for better pressing the electrode 2 onto the cavity wall of the receiving cavity 111. On the other hand, this is beneficial for preventing the pressing member 13 from causing wear to the conductive elastic member 15, and for protecting the conductive elastic member 15.

[0065] In some embodiments, both ends of the conductive elastic element 15 are fixedly connected to the mounting base 11.

[0066] exist Figure 4 In the illustrated embodiment, one end of the conductive elastic element 15 is fixedly connected to the mounting base 11, while the other end is suspended. This facilitates the deformation of the conductive elastic element 15, making it easier for the conductive elastic element 15 to deform toward the receiving cavity 111 as the pressing member 13 approaches the receiving cavity 111 along the first direction.

[0067] See Figures 2 to 4 The projection of the conductive elastic element 15 along the first direction intersects with the projection of the accommodating cavity 111 along the first direction, and the suspended end of the conductive elastic element 15 is directly opposite the crimp connector 132 along the first direction. This facilitates the conductive elastic element 15 to stably press the electrode 2 against the cavity wall of the accommodating cavity 111.

[0068] See Figure 4 The mounting base 11 is also provided with a limiting channel 112, which extends along the first direction to the receiving cavity 111. One end of the conductive elastic element 15 is suspended within the limiting channel 112. Along the second direction, the maximum gap between the pressure connector 132 and the limiting channel 112 is D1. The dimension of the conductive elastic element 15 in the second direction is D2, and D1 and D2 satisfy: D1 < D2. In this way, the conductive elastic element 15 is constrained by the limiting channel 112 and the pressure connector 132 on the sliding path of the pressure connector 132, which can ensure that the conductive elastic element 15 deforms toward the receiving cavity 111 under the action of the pressure connector 132.

[0069] See Figure 2 , Figure 3 , Figures 5 to 7 The accommodating cavity 111 is cylindrical, and its axis is perpendicular to the first direction. This facilitates the conductive elastic element 15 in stably pressing the electrode 2 against the cavity wall of the accommodating cavity 111.

[0070] See Figure 1 , Figure 2 and Figure 9 To facilitate the user to push the slider 14 to slide along the second direction, the slider 14 is provided with a force-applying part 141. The side of the force-applying part 141 away from the pressing part 13 is located outside the mounting base 11, and multiple ribs 142 are protruding on the side of the force-applying part 141 away from the pressing part 13. The multiple ribs 142 are evenly distributed along the second direction.

[0071] See Figures 1 to 9The present application further provides a neurostimulator, which includes an electrode 2, a pulse generator (not shown in the figure), and the aforementioned connector 1. The connector 12 is electrically connected to the pulse generator, and when the conductive elastic member 15 deforms toward the accommodating cavity 111, the conductive elastic member 15 presses the electrode 2 against the cavity wall of the accommodating cavity 111.

[0072] In this neurostimulator, when it is necessary to electrically connect electrode 2 to the pulse generator, electrode 2 is inserted into the receiving cavity 111. Then, the sliding member 14 slides along the positive direction of the second direction, thereby pushing the pressing member 13 closer to the receiving cavity 111 along the first direction. This causes the conductive elastic member 15 to deform towards the receiving cavity 111, so that the conductive elastic member 15 presses electrode 2 against the cavity wall of the receiving cavity 111. Meanwhile, the connector 12 is electrically connected to the pulse generator. In this way, the pulse generator and electrode 2 are electrically connected through the connector 12 and the conductive elastic member 15. Moreover, the conductive elastic member 15 presses electrode 2 against the cavity wall of the receiving cavity 111, ensuring the reliability of the connection between electrode 2 and connector 1. Thus, during surgery, electrode 2 and connector 1 remain reliably connected and will not loosen, facilitating the surgeon's operation.

[0073] When it is necessary to remove electrode 2 from connector 1, slide the slider 14 along the negative direction of the second direction until the conductive elastic element 15 returns to its natural state, and then pull out electrode 2.

[0074] Preferred options, please refer to Figure 1 and Figure 2 The cavity 111 is conformally fitted to the electrode 2, which facilitates the conductive elastic element 15 in stably abutting the electrode 2 against the cavity wall of the cavity 111. Figure 1 In the illustrated embodiment, both the accommodating cavity 111 and the electrode 2 are cylindrical. In other embodiments, both the accommodating cavity 111 and the electrode 2 may be rectangular.

[0075] See Figure 2 Electrode 2 includes a conduit 21, a connecting contact 22, and a stimulation contact 23. Both the connecting contact 22 and the stimulation contact 23 are fixed to the conduit 21. The stimulation contact 23 is electrically connected to the connecting contact 22. Electrode 2 applies electrical stimulation to the patient's nerves through the stimulation contact 23. When the conductive elastic element 15 deforms towards the accommodating cavity 111, the conductive elastic element 15 presses against the connecting contact 22 and presses the electrode 2 against the cavity wall of the accommodating cavity 111. Thus, the pulse generator and the stimulation contact 23 are electrically connected through the connector 12, the conductive elastic element 15, and the connecting contact 22.

[0076] See Figure 2In connector 1, multiple conductive elastic elements 15, crimp connectors 132, connection contacts 22, and stimulation contacts 23 are provided and are arranged in a one-to-one correspondence. When the conductive elastic element 15 is deformed toward the receiving cavity 111, each conductive elastic element 15 is crimped to the corresponding connection contact 22 and the electrode 2 is crimped to the cavity wall of the receiving cavity 111.

[0077] See Figure 1 and Figure 5 To facilitate application of the mounting base 11 to human skin, the mounting base 11 is box-shaped. To ensure the safe use of the connector 1 and protect the circuit structure of the connector 1, the conductive elastic element 15 is entirely located within the mounting base 11, and the connector 12 is at least partially located within the mounting base 11.

[0078] See Figures 1 to 7 To facilitate the assembly of connector 1, mounting base 11 is assembled from first part 113 and second part 114. First part 113 and second part 114 are detachably connected and together restrict the position of connector 12, crimping member 13 and sliding member 14. One end of conductive elastic member 15 is fixed to either first part 113 or second part 114.

[0079] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0080] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of protection of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the appended claims.
