 本发明的实施方式
参照图1及图2所示，本发明一种胶囊内窥镜的具体实施方式包括：胶囊状壳体1以及内置于其中的成像系统2、照明系统3、信号收发系统4和电源5，其中，所述电源5分别与成像系统2、照明系统3和信号收发系统4电连接，所述胶囊状壳体1的一端或两端设有透明的镜头盖10，成像系统2包括至少一组镜头20，所述信号收发系统4包括天线40和射频电路，所述天线40装设于镜头20的外周，所述镜头20透过壳体前端的镜头盖10拍摄并采集体腔内的图像，将所述图像经由天线发射至检测设备中。
其中，胶囊状壳体1用于收纳所述成像系统2、照明系统3、信号收发系统4和电源5，可通过口服进入人体的腹腔的肠道或胃中，通过成像系统2拍摄肠道或胃中的图像，并将其所采集的图像数据通过信号收发系统4发送至外部检测设备中，以供医生实时获知待测人体的肠道或胃中的状况，对其进行观察和检测，以帮助诊断治疗。
结合参照图2所示，所述胶囊内窥镜进一步包括电路板6，所述电路板6上设有与天线40电连接的射频电路60、与镜头电连接的视频传感电路62以及控制电路64。所述射频电路60、视频传感电路62和控制电路64集成于电路板6上，所述视频传感电路62将镜头20所摄取的图像数据传送至所述射频电路60上，再经由天线40发送至外部的检测设备以供检测，所述控制电路64用于接受外部检测设备发出的指令，以对射频电路60和视频传感电路62进行控制。
所述成像系统2包括至少一组镜头20和视频传感电路62，视频传感电路62与镜头电性相连，对所述镜头20在人体肠道或胃中所摄的图像或影像进行采集并保存，并传输至射频电路60，经由天线40发射至外部的检测设备中。在本发明的优选实施例中，所述成像系统包括两组镜头20，其分别装设于电路板的两侧上，且与胶囊两端的透明镜头盖10相对，分别拍摄并采集胶囊两端的图像和影像，以增大了胶囊在肠道或胃中的拍摄范围，扩大了检测的范围，提高了检测的可靠度。
在本发明的优选实施例中，所述天线40由金属线圈制成，盘旋地缠绕于一镜头20的外周，其一端连接于所述电路板6的射频电路60，另一自由端以镜头20为柱状轴心盘旋地环绕于镜头20上。将天线40制成线圈状盘绕于镜头20上，可增大天线的发射信号强度，同时，缠绕于镜头上，减少了所占面积，使得整体胶囊内窥镜轻便小型化，并且，所述缠绕于镜头上的天线，远离电源，可有效减少电源对天线收发信号产生的电磁干扰，提高图像的清晰度。在本发明的具体实施方式中，所述电源5与天线40之间的间距为6-10mm，优选间距为8mm，所述电源5和天线40之间的间距为应为越大越好，从而保证电池5对天线40性能的影响最小。所述天线40的高度为4-8mm，优选高度为6mm。所述天线40的匝数为3-5匝，优选匝数为3.5匝。其中，对天线收发信号产生的电磁干扰的干扰器件不仅仅只包括电池，还可包括胶囊内窥镜中的其他器件，例如：电路。
可以理解，所述天线40亦可以竖立于镜头20的两侧，与镜头20相平行，通过环设于镜头20的外周边上的天线40向外部的检测设备发送所摄的图像或影像数据。这样，既可增大了天线的发射信号强度，又可减少其所占面积，有效地利用了胶囊空间，提高了天线的性能。
