具体实施方式
下面将结合附图对本发明的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
如图1和图3所示，本实施例的吸引装置包括：吸引本体10和手柄20，吸引本体10的前端具有吸引口，手柄20可拆卸地连接在吸引本体10的后端上。
应用本实施例的吸引装置，手柄20可拆卸地连接在吸引本体10上，上述结构在使用后将手柄从吸引本体上拆卸下来，由于手柄占吸引装置成本的绝大部分且手柄在使用时并未与患者直接接触，只需丢弃利用后的吸引本体，实现手柄的重复使用，大幅降低使用成本且不存在健康隐患。
在本实施例中，如图4所示，手柄20具有卡扣21，卡扣21卡住吸引本体10。拆卸手柄20时，将吸引本体10从卡扣21脱出，这样就将手柄20与吸引本体10拆开，手柄20可以重复使用，节约能源，降低患者的治疗成本。优选地，卡扣21为Ω形的卡接口。卡接牢固，拆装简便。
为了防止手柄20和吸引本体10之间发生相互转动，吸引本体10具有第一止转面，手柄20上设有与第一止转面配合的第二止转面221。第一止转面和第二止转面221相互配合阻止手柄20和吸引本体10之间发生相互转动的情况，便于操作，进而保证手术安全可靠。
在本实施例中，如图2、图5和图7所示，手柄20的底面形成第二止 转面221，吸引本体10具有止转块13，止转块13包括垂直于吸引本体10的轴线的径向块和平行于吸引本体10的轴线的轴向块，轴向块的朝向手柄20的表面形成第一止转面，径向块的朝向手柄20的表面形成限位面。止转块13既具有止转的作用，又具有限位的作用。优选地，止转块13为两个，两个止转块13相向设置，两个径向块之间形成用于限制手柄20的限位空间。当然，止转结构的结构形式也并不限于此。
在本实施例中，如图6所示，吸引装置还包括用于采集吸引口周围的图像的摄像头组件30，吸引本体10包括相互独立的吸引腔14和安装腔15，吸引口与吸引腔14连通，摄像头组件30可拆卸地安装在安装腔15的前端。吸引腔的后端接负压，用于吸引胚胎组织。上述结构可以保证摄像头组件30不与患者进行接触，重复使用摄像头组件30，有利于降低患者治疗成本。当然，吸引本体也可以为单腔体，单腔体与吸引口连通，摄像头组件可拆卸地安装在单腔体的前端，柔性电路板的前端与摄像头组件连接，柔性电路板的后端穿入单腔体内并从吸引本体的后端穿出连接在手柄上，柔性电路板与手柄内的电路板电连接，柔性电路板被包覆在套管中，套管紧贴在单腔体的内壁上。
在本实施例中，如图5所示，吸引装置还包括柔性电路板40，柔性电路的前端从吸引本体10的后端伸入安装腔15中与摄像头组件30连接，柔性电路板40的后端连接在手柄20的后端上并与手柄20内的电路板电连接。柔性电路板40也不与患者进行接触，重复使用柔性电路板40，进一步降低成本。组装时，将手柄放置在两个止转块之间，用手握住吸引本体前端用力往下压，将手柄安装在吸引本体上。拆卸时，拔掉手柄上的柔性电路板40的尾部端子，用手握住吸引本体前端用力向下拉，取下吸引本体，实现 手柄和吸引本体拆分；然后将柔性电路板40和摄像头组件30拉出来，取出柔性电路板40和摄像头组件30。
在本实施例中，柔性电路板40通过线缆与手柄20连接，线缆与手柄30的连接方式类似于USB接口或网线接口的连接方式。
在本实施例中，吸引本体10包括相连接的管身11和透明头罩12，压力传感器51设置在透明头罩12内。
在本实施例中，如图5所示，手柄20包括下手柄22和上手柄23，卡扣设置在下手柄22上，下手柄22和上手柄23扣合并形成安装腔体。
为了避免在手术过程中吸引本体进入深度不当容易产生子宫内膜穿孔的情况，在本实施例中，如图6所示，吸引装置还包括压力反馈装置，压力反馈装置还包括压力传感器51、压力传感器线52、控制模块和警示模块，压力传感器51设置在吸引本体10的前端，压力传感器51与压力传感器线52的前端相连，压力传感器线52的后端插接在手柄20的后端上并与控制模块电连接，压力传感器51检测吸引本体10的前端所受到的压力值并传输至控制模块，控制模块的输出端连接警示模块的输入端。吸引装置在子宫内所感受到的压力因其所处的位置不同而不同，当吸引装置的前端越靠近子宫底部，其所承受的压力就越大，采用压力传感器来判断吸引管是否达到子宫底部和随时反馈压力大小，具备更佳的安全性和便利性，有效地避免压力过大造成子宫损伤。控制模块和警示模块均设置在手柄内，压力传感器51通过压力传感器线52与手柄内的控制模块和警示模块连接，压力传感器线52的后端插接在手柄20的后端，这样便于将压力传感器线52与手柄分离，拆卸时只需将压力传感器线52的后端端子从手柄上拔下来。
在本实施例中，摄像头组件30通过柔性电路板40与手柄20的后端连接，压力传感器51通过压力传感器51与手柄20的后端连接。当然，摄像头组件和压力传感器也可以均与传输线或柔性电路板连接，传输线或柔性电路板插接在手柄的后端上，这样简化了结构，拆卸更简便。
在本实施例中，警示模块可以是压力值显示模块，控制器压力值信号输出端连接压力值显示模块输入端。控制器将其所接收到的压力值显示于压力值显示模块上，方便医生更直观的了解吸引本体的前端所受到的压力值，从而有助于医生做出正确的判断。
作为可变换的实施例中，警示模块也可以是报警模块，控制器报警信号输出端连接报警模块驱动端。此时，控制器包括比较器，比较器第一输入端连接信号处理模块输出端，比较器第二输入端连接控制器的压力阈值输出端，比较器输出端连接报警模块驱动端。当压力传感器检测到的压力值超过控制器内设定的压力阈值时，报警模块发出警报以警示医生注意吸引本体的前端已经到达宫底。报警模块可以为但不局限于声光报警器。当然，警示模块可以同时包括报警模块和压力值显示模块。
现有技术中，图像数据通过1.5m以上的导线与图像处理及显示装置进行通讯，而吸引本体的尾部还需要连接负压吸引器，因此过多的线缆会影响医生手术操作的便利，线缆的天线效应还会引入无线电干扰降低图像质量，同时，内窥镜加图像处理主机的架构比较复杂，在注册检验时也较难通过EMC测试，而且手术后导线需要消毒或者丢弃，这给医院带来了时间和费用的增加。
针对上述技术问题，在本实施例中，吸引装置还包括无线收发模块60， 无线收发模安装在手柄20的内腔中，用于发送数据和接收数据。图像数据的传输就不需要用导线来进行传输，便于医生手术操作的便利，还提高系统的干扰能力。
本发明还提供了一种吸引装置的视频图像传输方法，该视频图像传输方法包括：将采集到的视频图像的数据分为第一类数据和第二类数据；发送第一类数据之后，发送第二类数据。这样分类发送，可以根据具体情况选择发送的数据。
在本实施例中，如图8所示，第一类数据为重要数据，视频图像的中间部分的数据为重要数据，第二类数据为非重要数据，视频图像的边缘部分的数据为非重要数据。摄像头组件采用广角镜头，被观察物距离镜头很近，导致图像边缘部分畸变很大。因此，图像的中间部分的镜头的畸变最小，也是人眼观察最仔细的部分，此部分为重要数据，图像的边缘部分位于镜头成像部分的边缘，畸变比较明显，光强也比较弱，划为非重要数据。通过对采集的图像的数据进行分类，并设置不同的优先级进行传输，重要数据保证视频图像流畅性，非重要数据保证视频图像清晰度，解决无线视频图像传输容易出现花屏、延时时间长等问题。优选地，视频图像呈矩形。
在本实施例中，重要数据包括正常重要数据和重传重要数据，在发送重要数据时，先发送正常重要数据，再发送重传重要数据。非重要数据包括正常非重要数据和重传非重要数据，在发送非重要数据时，先发送正常非重要数据，再发送重传非重要数据。从上述可知，发送数据的顺序依次为：正常重要数据、重传重要数据、正常非重要数据、重传非重要数据。图像数据被分为许多小数据包依次发送，每个数据包有一个包序号例如从 0～255，接受端可以从序号来判断是否有丢包，可以要求发送端重传。具体地，判断第一个数据包是否为重要数据，第一个数据包是重要数据时发送端发送该数据包，第一个数据包是非重要数据时进行缓存；发送完第一个数据包之后更新数据包，新的数据包进行上述操作；等所有重要数据发送完毕之后发送非重要数据。接收端检测所有发送端发送的数据是否完整，数据不完整时发送重发数据、包序号等。
在本实施例中，视频图像被分为N行N列的子图像，在子图像的行数大于等于A且小于等于B和列数大于等于C小于等于D时，子图像的数据为重要数据，其中，1＜A＜B＜N，1＜C＜D＜N。例如，一帧图像被分为N行N列的子图像，每个子图像都可以由列和行来表示坐标，同时满足列数40～400和行数60～580两个条件的子图像的数据为重要数据，其他部分的为非重要数据。
显然，上述实施例仅仅是为清楚地说明所作的举例，而并非对实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。而由此所引伸出的显而易见的变化或变动仍处于本发明创造的保护范围之中。
