请参考图6，在一个实施例中，穿戴式超声刺激正中神经装置还包括均与超声成像件22电性连接的超声成像信号发生器51以及成像显示器52。可以理解地，超声成像信号发生器51通过信号传输线将电信号传输至超声成像件22，从而产生超声信号，传输至人体组织处，同时，反馈的超声信号通过信号传输线传输至成像显示器52上，用于探查正中神经的位置，并且，探查过程中可通过转动穿戴套环10来调整超声成像件22的探查位置。
请参考图7，在一个实施例中，穿戴式超声刺激正中神经装置还包括用于采集用户生理数据的辅助反馈装置60，辅助反馈装置60向超声刺激件21反馈当前用户的生理数据信号。可以理解地，辅助反馈装置60可为其他检测医疗装置，例如，心电扫描设备、磁共振设备以及生物影像设备等，而其中的生理数据可为电生理信号及影像学信号，其中，电生理信号可为脑电信号、肌电信号、心电信号等，而影像学信号可为磁共振信号、计算机断层扫描信号、超声信号等。即通过辅助反馈装置60呈现的生理数据作为定位正中神经的辅助数据，从而提高定位精度和效率。
请参考图2，在一个实施例中，穿戴套环10包括沿径向方向依次层叠设置的上固定环11a、转动环12a以及下固定环13a，转动环12a绕于中轴线且于上固定环11a与下固定环13a之间做阻尼转动，各超声换能组件20穿设于转动环12a上。可以理解地，该穿戴套环10呈“三明治”结构。上固定环11a和下固定环13a在穿戴后保持静止，转动环12a呈绕于中轴线相对上固定环11a或下固定环13a转动，从而仅调整转动环12a的位置即可改变超声换能组件20的刺激位置。具体地，穿戴套环10还包括设于上固定环11a与转动环12a之间的第一阻尼轴承组14a，以及设于下固定环13a与转动环12a之间的第二阻尼轴承组15a。可以理解地，通过第一阻尼轴承组14a和第二阻尼轴承组15a使得转动环12a发生相对转动和稳定停滞，即满足超声换能组件20位置可改变的前提下，又能实现刺激位置固定的要求。
请参考图3，在另一个实施例中，穿戴套环10包括可拆卸连接地第一半圆环11b和第二半圆环12b。可以理解地，通过两个可拆装的半圆环能够提高佩戴过程中的通用性和舒适性。
具体地，请参考图3、图5和图6，第一半圆环11b与第二半圆环12b通过磁吸方式进行可拆卸连接。即在第一半圆环11b与第二半圆环12b的连接处设有磁吸件13b。这里，磁性件13b为可相互磁吸的磁体，或者，磁体与可与之磁吸的金属。
具体地，请参考图3，第一半圆环11b与第二半圆环12b的连接处设有定位导向结构14b。这里，定位导向结构14b的作用是提高第一半圆环11b和第二半圆环12b的装配速度以及二者之间连接稳定性。例如，定位导向结构14b包括设于第一半圆环11b上的凸部14b1以及开设于第二半圆环12b上的凹部14b2，凸部14b1与凹部14b2相适配，这样，利用凸凹配合以避免第一半圆环11b和第二半圆环12b在连接处沿径向方向被直接打开。根据实际使用需求，在第一半圆环11b上开设凹部，以及在第二半圆环12b上设置凸部。
请参考图4，在另一个实施例中，第一半圆环11b与第二半圆环12b的连接处设有卡扣结构15b。除了通过磁吸方式实现可拆卸连接，还可通过卡扣连接方式。即在第一半圆环11b上设置卡接臂15b1，而在第二半圆环12b上设置卡接环15b2。当然，卡接臂和卡接环位置可以调换。
综上，本申请的穿戴式超声刺激正中神经装置，通过穿戴套环10穿套于人体的腕处进行固定，利用其中的超声成像件22发出超声能量和接收超声能量以获取正中神经的位置图像，并且，通过转动穿戴套环10进行位置调整，最后，利用其中的超声刺激件21发出超声能量至正中神经处，对正中神经起调控作用。其中，穿戴套环10包括可拆卸连接地第一半圆环11b和第二半圆环12b，例如，通过磁吸或卡扣连接的方式进行可拆卸连接。同时，穿戴套环10包括沿径向方向依次层叠设置的上固定环11a、转动环12a以及下固定环13a，转动环12a绕于中轴线且于上固定环11a与下固定环13a之间做阻尼转动。即通过绕轴线转动设有多个超声换能组件20的转动环12a，来改变各超声换组组件20的位置，以达到切换各超声换能组件20的位置的目的。以及，在穿戴套环10的内侧设有与用户腕处相接触的超声耦合层30，从而提高穿戴套环10与用户腕处的贴合程度，提高超声能量的传导效率。同时，穿戴式超声刺激正中神经装置还包括用于与超声刺激件21电性连接的超声刺激信号发生器40；均与超声成像件22电性连接的超声成像信号发生器51以及成像显示器52；以及用于采集用户生理数据的辅助反馈装置60，辅助反馈装置60向超声刺激件21反馈当前用户的生理数据信号。
以上仅为本申请的可选实施例而已，并不用于限制本申请。对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的权利要求范围之内。
