具体实施方式
下面结合图表和实施例，对本申请的具体实施方式作进一步详细描述。以下实施例用于说明本申请，但不用来限制本申请的范围。
参见图1和图2，在现有技术中，神经电刺激设备的现有连接组件10是单独的，在装配中根据需求通道连接块数量的多少，选择相应的数量的通道连接块组装而成，例如需求4通道就选择4个通道连接块组装而成，通道连接块至少由弹簧圈101、绝缘环102和金属环103组成，通过金属环103和弹簧圈101接触进行导通。神经电刺激设备的通道连接块与主板的连接依靠馈通引线104连接。
参见图2，在现有技术中，弹簧圈101、绝缘环102和金属环103构成通道连接块，电极导线的插接端30安装进入通道连接块内部，插接端30上的多个触点分别与弹簧圈101接触以实现电连接，并继续连通与弹簧圈101接触的金属环103以及电连接金属环103的其他电路，最终实现神经电刺激设备内的电路和神经电刺激电极的电连接。多个交替的绝缘环102和金属环103组装而成通道连接块，使得通道连接块的体积较大，给患者带来较大创伤，并且生产组装不方便，产生装配误差，导致产品一致性差的问题
另外，在实际应用中，馈通引线104需要弯折，才能和通道连接块中的金属环103焊接在一起，为了保证馈通引线104的弯折强度，需要给馈通引线104足够的空间，并且为了便于焊接，通道连接块也要有足够的体积。产生通道连接块体积大，焊接不容易操作的问题。
参加图3，为解决上述技术问题，本申请实施例提供一种神经电刺激设备的连接模块20，用于与电极导线电连接，电极导线的一端通过连接连接模块20连接神经电刺激设备，电极导线的另一端连接电极。
所述连接模块20可以包括：第一绝缘本体201，所述第一绝缘本体201具有第一外表面202和连接通道203，所述连接通道203用于安装电极导线的插接端30，所述连接通道203内设置有多个第一电连接触点204，所述第一电连接触点204用于与所述电极导线的插接触点301电连接；所述连接模块20还包括：多个第二电连接触点205、多个第一电路206；每个所述第二电连接触点205设置于所述第一外表面202，并分别通过所述第一电路206电连接所述第一电连接触点204。
需要说明的是，在图3中，为展示方便，第一电连接触点204、第二电连接触点205和第一电路206的数量均仅示出1个，图3仅作为示意图，其中的部件数量并非对本申请范围的限制，在其他实施方式中，第一电连接触点204、第二电连接触点205和第一电路206的数量还可以分别设置更多个。
其中，在本申请中，所述电连接触点仅代指实现电连接的电接触位置，并非限定为一个特定的点状结构，例如是，可以在第一外表面202额外设置凸起结构，该凸起结构与第一电路206电连接，该凸起结构可以与导线进行焊接以实现电连接，此时，该凸起结构可以作为第二电连接触点205，或者是，不额外设置凸起 结构，而是将第一电路206继续延伸或扩展一部分，该部分可以与导体进行焊接或搭接以实现电连接，则该延伸部或扩展部可以作为第二电连接触点205，亦或是，第一电路206在连接通道203内延伸一部分，该部分可以与电极导线插接端30上的多个触点直接接触或通过中间导电部件(例如金属弹簧圈208)间接接触，实现电连接，则该第一电路206在连接通道203内的延伸部可以作为第一电连接触点204。
由此，在第一绝缘本体201上设置第一电连接触点204、第一电路206和第二电连接触点205，替代现有技术中相互交替的绝缘环102和金属环103的结构，实现与电极导线电连接的功能，该技术方案中的连接模块20结构紧凑，体积小，对患者的创伤更小，且无需进行绝缘环102和金属环103的组装，节省工序，没有装配误差，产品的一致性好。
参见图4，在一些实施方式中，所述连接模块20还可以包括多个弹性电连接件207，多个所述弹性电连接件207设置于所述连接通道203的内部，并沿所述连接通道203长度方向直线排列，每个所述弹性电连接件207分别与一个所述第一电连接触点204电连接并分别用于与所述电极导线的一个插接触点301电连接。由此，利用弹性电连接件207实现第一电连接触点204与电极导线的插接端30上的一个触点电连接，弹性电连接件207具有弹性，使得第一电连接触点204与电极导线的插接端30上的一个触点的电连接更加稳定。
继续参见图4，在一些实施方式中，所述弹性电连接件207可以为金属弹簧圈208，金属弹簧圈208例如是斜圈弹簧，多个所述金属弹簧圈208用于一一套接在所述电极导线的插接端30的多个插接触点301上。由此，金属弹簧圈208与电极导线的插接触点301可以进行环形接触，电接触更加稳定，同时，金属弹簧圈208套接电极导线的插接端30，对插接端30具有限位作用，防止插接端30脱离连接通道203，能够增强插接端30安装的稳定性。
参见图5、图6和图7，在一些实施方式中，所述第一绝缘本体201至少由第一绝缘组件40和第二绝缘组件50组合而成，所述第一绝缘组件40和/或第二绝缘组件50的材质可以包括陶瓷或塑胶；所述第一绝缘组件40和第二绝缘组件50可以包括沿所述连接通道203长度方向直线排列的多个弧形凹槽401，当所述第一绝缘组件40和第二绝缘组件50组合形成所述第一绝缘本体201时，所述金 属弹簧圈208的至少部分结构容置于所述弧形凹槽401内；所述第一电连接触点204设置于所述弧形凹槽401内部的至少与所述金属弹簧圈208相抵接的部分表面。
其中，当第一绝缘组件40或第二绝缘组件50的材质包括陶瓷时，优选的陶瓷材料为生物陶瓷或复合生物陶瓷材料以及涂层生物陶瓷材料，例如利用钛合金作为基体，全部外表面喷涂生物陶瓷涂层所形成的涂层生物陶瓷材料；当第一绝缘组件40或第二绝缘组件50的材质包括塑胶时，优选采用PEEK材料，PEEK材料具有耐高温、自润滑、易加工和高机械强度的优点，能够方便第一绝缘组件40和第二绝缘组件50的加工成型，同时较高的机械强度提高了神经电刺激设备的使用寿命。
由此，利用分体结构组合成为第一绝缘本体201，使得第一绝缘本体201的制造更为方便，同时，也方便在第一绝缘本体201上构建第一电连接触点204和第一电路206，以及方便将金属弹簧圈208组装进入第一通道中；多个弧形凹槽401对于金属弹簧圈208具有限位作用，使得金属弹簧圈208的安装和电接触更加稳固牢靠。
继续参见图5和图6，在一些实施方式中，所述第一绝缘本体201可以包括多个第一孔结构402，所述第一孔结构402连通所述第一外表面202和连接通道203，所述第一电路206包括设置于所述第一绝缘本体201的第一外表面202的第一表面电路403和设置于所述第一孔结构402中的第一孔电路(未示出，下同)；所述第一表面电路403电连接所述第二电连接触点205和所述第一孔电路，所述第一孔电路电连接所述第一电连接触点204。
其中，第一孔电路可以利用孔中填塞导电材料的方法形成，也可以利用孔中电镀导电层的方法形成。
由此，在第一绝缘本体201上构建第一表面电路403，并设置第一孔结构402，利用第一孔结构402构建第一孔电路用以实现上述电连接，孔结构的设置比起单纯设置第一绝缘本体201表面的电路，可以方便的实现第一外表面202和连接通道203的内表面的电连接，同时，第一孔结构402对于第一孔电路具有一定的保护和限位作用，避免第一孔电路被破坏，提高了电路的耐久性。
在一些实施方式中，所述第一表面电路403、第一孔电路、第一电连接触点 204和第二电连接触点205可以为导电膜。
其中，导电膜可以利用镀膜工艺，例如电镀、磁控溅射、CVD等工艺实现在第一绝缘本体201上构建膜电路，作为第一表面电路403、第一孔电路、第一电连接触点204和第二电连接触点205，优选的，可以利用电镀的方法形成上述膜电路，电镀的方法成本低，产能大，膜电路与第一绝缘本体201的结合力高；进一步优选的，电镀的种类包括电镀金或电镀钛或两者的组合。
由此，可以利用多种镀膜工艺形成导电膜，利用导电膜构建第一表面电路403、第一孔电路、第一电连接触点204和第二电连接触点205，便于规模化生产，并提高产品的一致性。
本申请实施例还提供一种神经电刺激设备的连接装置，包括连接模块20和如图8及图9所示的馈通模块60，所述连接模块20为上述任一实施例提供的连接模块20；所述馈通模块60包括第二绝缘本体601和设置于第二绝缘本体601上的多个第三电连接触点602、第四电连接触点603和多个第二电路604，每个所述第三电连接触点602分别通过至少一个所述第二电路604电连接至少一个所述第四电连接触点603；当所述连接模块20和馈通模块60电连接时，每个所述第三电连接触点602分别与至少一个所述第二电连接触点205电连接。由此，利用馈通模块60作为中间模块，实现神经电刺激设备内的电路与连接模块20的电连接，使得电连接模块20化，便于实现标准化生产。
在一些实施方式中，所述第三电连接触点602与所述第二电连接触点205的电连接方式为金线焊接。
金线焊接的方式例如图10所示，其中，利用焊接金线70连接第三电连接触点602与第二电连接触点205。
由此，金线焊接能够实现自动化生产，提高生产效率，提高生产标准化水平，降低生产成本，提高产品一致性，并且，金线焊接的电连接方式相比于导线焊接更加稳定牢靠。
继续参见图8和图9，在一些实施方式中，所述第二绝缘本体601包括多个第二孔结构605，所述第二孔结构605贯穿所述第二绝缘本体601的第一表面606和第二表面607，所述第三电连接触点602设置于所述第二绝缘本体601的第一表面606，所述第四电连接触点603设置于所述第二绝缘本体601的第二表面 607，所述第二电路604包括设置于所述第二绝缘本体601的第一表面606的第二表面电路608和设置于所述第二孔结构605中的第二孔电路(未示出，下同)，所述第二表面电路608电连接所述第三电连接触点602和第二孔电路，所述第二孔电路电连接所述第四电连接触点603。
其中，第二孔电路可以利用孔中填塞导电材料的方法形成，也可以利用孔中电镀导电层的方法形成。
由此，第二孔结构605的设置比起单纯设置第二绝缘本体601表面的电路，可以方便的实现第一表面606和第二表面607的电连接，同时，第二孔结构605对于第二孔电路具有一定的保护和限位作用，避免第二孔电路被破坏，提高了电路的耐久性。
