实施例一
如图1至12所示为一种具有冲吸功能的消融电极装置的第一实施例，消融电极装置包括电切电凝组件1、冲洗组件2、吸引组件3，电切电凝组件1、冲洗组件2、吸引组件3均设有相互独立的控制组件，电切电凝组件1包括刀头组件11和用于控制刀头组件11进行电切电凝的第一控制组件12，冲洗组件2设有用于冲洗介质流通的冲洗管道21和第二控制组件，吸引组件3包括吸引管道31和第三控制组件。
需要说明的是，本实施例的具有冲吸功能的消融电极装置为手柄式结构，整体既方便操作，同时又很精巧。
其中，电切电凝组件1包括刀头组件11和用于控制刀头组件11进行电切电凝的第一控制组件12，第一控制组件12包括控制按钮121和控制电路板122，控制电路板122设有用于控制电切的第一开关123和用于控制电凝的第二开关124，控制按钮121设有用于按压第一开关123的第一触发部125和用于按压第二开关124的第二触发部126。在本实施例中，操作人员按压控制按钮121上的第一触发部125，第一触发部125按压第一开关123，使得第一开关123导通，控制电路板122对消融电极装置进行控制，进行电切功能；操作人员按压按钮上的第二触发部126，第二触发部126按压第二开关124，使得第二开关124导通，控制电路板122对消融电极装置进行控制，进行电切电凝功能。
另外，控制按钮121上设有两个凸起部，两个凸起部分别为第一触发部125和第二触发部126，两个凸起部之间设有凹部127。这样设置是便于操作者像握手枪的方式放两个手指，设置凸起部便于手指放置，同时中间设有凹部127，使得两个手指放置的位置之间具有距离，避免手滑相互产生触碰，避免误操作，提高操作的精准性和方便性。
其中，第一控制组件12还包括固定架6，控制电路板122与固定架6固定连接，控制按钮121与固定架6转动连接。这样设置是为了便于固定控制电路板122和控制按钮121。
另外，控制按钮121上设置有连接孔61，固定架6上设有连接杆62，固定架6利用连接杆62穿过连接孔61与控制旋钮121转动连接。在本实施例中，连接孔61设置在控制按钮121的中部，可方便转动控制按钮121；另外同时连接杆62与连接孔61之间设有扭转弹簧，这样设置是为了使控制按钮121自动复位。
另外，两个凸起部的端部均设有便于手指放置的凹陷结构，且上面设有防滑结构，这样设置是便于操作，避免出现打滑现象。
其中，刀头组件11包括用于电切电凝的切割刀头111和用于冲洗或吸引的介质通过的刀管112，冲洗组件2设有用于冲洗介质流通的冲洗管道21和第一弹性导通机构22，冲洗管道21一端通过第一弹性导通机构22与刀管连通或断开，另一端为自由端。冲洗管道21用于将消融电极与生理盐水管连接，第一弹性导通机构22的设置使医务工作人员能够根据实际冲洗需求将冲洗管道21与刀管112进行选择性导通或不导通，提高操作便利性。
其中，第一弹性导通机构22包括阀座23、阀芯24，阀座23设有第一管道231以及第二管道232，第二管道232设于第一管道231的侧壁上并与第一管道231相连通；刀管112与第一管道231连通，冲洗管道21与第二管道232连通；阀芯24与第一管道231活动连接且控制第一管道231与第二管道232连通或断开；第一弹性导通机构22还设有用于将在第一管道231活动的阀芯24进行位置锁紧或松开的锁紧开关25。
另外，阀芯24一端滑动安装于第一管道231内，另一端为自由端且设有用于按压的按压部241；阀芯24安装于第一管道231内的一端设有通道结构242，通道结构242设有相连通的第一端口243和第二端口244，第一端口243与所述第一管道231相连通，第二端口244与第二管道232相连通。一般情况下，按压部241可做成尺寸较大的结构或者上面设置橡胶结构，这样通过增加按压部241的受力面积进或境地缓冲力，方便操作人员的按压，提高舒适度。
其中，锁紧开关25包括锁紧部251以及用于与锁紧部251连接的连接部252，连接部252安装在阀芯24上，锁紧部251安装在阀座23上；操作按压部241，阀芯24在第一管道231内滑动，锁紧部251与连接部252连接或脱离；锁紧部251与连接部252相连时，第一管道231与第二管道232相连通；锁紧部251与连接部252脱离时，第一管道231与第二管道232断开。具体的工作原理：当操作人员按压阀芯24时，阀芯24向第一管道231中滑动，当通道结构242与第二管道232相连通时，锁紧开关25中的锁紧部251锁紧连接部252，第一管道231、第二管道232以及通道结构242形成通路；当操作人员再次按压阀芯24时，锁紧开关25使阀芯24复位，锁紧部251与连接部252相脱离，通道结构242的端口与第一管道231的内壁相贴合，第二管道232的管道口与阀芯24的外壁相贴 合，第一管道231、第二管道232以及通道结构242形成的通路断开。
其中，锁紧部251包括外壳253、用于与连接部252相连的卡扣254以及第一弹簧258，卡扣254安装在外壳253中并与其滑动连接，外壳253上设有导向槽261，卡扣254上设置有滑块259，滑块259安装在导向槽261中，第一弹簧258设置于外壳253中，第一弹簧258与滑块259相连接。
另外，卡扣254包括卡扣本体255以及用于形成与连接部252卡接的剪刀式扣接结构的第一卡接支部256与第二卡接支部257，第一卡接支部256与第二卡接支部257安装在卡扣本体255的一端。具体地：当操作人员按压阀芯24时，阀芯24推动卡扣254向外壳253中滑动，当卡扣254向外壳253中滑动一段距离后，外壳253的口部与第一卡接支部256与第二卡接支部257相抵接，当阀芯24继续推动卡扣254向外壳253中滑动时，外壳253通过挤压第一卡接支部256与第二卡接支部257，使得第一卡接支部256与第二卡接支部257越来越贴合，进而锁定连接部252，当操作人员再次按压阀芯24，滑块259在第一弹簧258的作用下推动卡扣254滑出外壳253，同时第一卡接支部256与第二卡接支部257与外壳253相脱离，第一卡接支部256与第二卡接支部257相互弹开松开连接部252。需要说明的是，第一卡接支部256与第二卡接支部257均为弹性结构，这样设置一方面是为了保证卡接与松开工作的顺利进行，同时避免为刚性的结构出现多次操作会出现断落的情况出现，提高其使用寿命。当然这些是优选，其他类似的结构只要能够实现该工作目标都是可行的。
其中，阀芯24上还套设有用于快速复位的第二弹簧245。在本实施例中，当按压阀芯24时，阀芯24向阀座23中滑动，在锁紧开关25的作用下，第二弹簧245处于挤压状态，当操作人员再次按压阀芯24，在阀芯24复位时，挤压状态的第二弹簧245作用给阀芯24复位方向上一个推力，这样可以使复位更快速。
另外，阀芯24位于第一管道231中的外周面上设有若干凹槽246，凹槽246中设置有密封圈。在本实施例中，密封圈的设置加强了阀芯24与第一管道231连接处的密封性，避免阀芯24与第一管道231连连接处发生渗透现象。

另外，刀管112的外部套设有套管115，消融电极装置还设有转轮116和用于实现刀管112伸缩功能的驱动机构。刀管112通过连接件117与转轮116插接。套管115通过连接件117与驱动机构连接。
具体地，连接件117包括第一连接件118和与第一连接件118轴向滑动连接的第二连接件119，第一连接件118的两端分别与套管115、驱动机构固连，刀管112穿过第一连接件118后与第二连接件119固连，且第一连接件118与转轮116内壁滑动连接。
驱动机构包括推杆电机、第三按钮5，第三按钮5伸出消融电极装置，推杆电机的推杆与第一连接件118连接，推杆电机设于手柄1内。当需要调整套管115伸缩时，按压第三按钮5使其与推杆电机接通，推杆电机的推杆伸出或回缩并推动第一连接件118相对于第二连接件119向前或向后移动，使得套管115相对于刀管112向前或向后移动，实现套管115的伸缩，切割刀头111能够根据实际需求露出套管115或收纳于套管115内。
当需要调整切割刀头111角度时，通过转动转轮116，使转轮116带动第一连接件118、第二连接件119转动，实现切割刀头111旋转角度的调整。
另外，具有冲吸功能的消融电极装置还包括壳体7，刀头组件11安装于壳体7的一端整体形成手柄式结构，控制按钮121与扳机323均设于手柄式结构的手握部，控制按钮121设于扳机323的上方，按压部241设于手柄式结构的与刀头组件连接端相对的另一端。这样的布局设置使得医务人员使用的过程中，食指和中指放置于控制按钮121的第一触发部125和第二触发部126上，无名指和小手指可以直接放置于扳机323的位置对其进行按压控制，拇指放置于按压部241位置处。这样电切电凝组件、冲洗组件、吸引组件均被独立控制，且操作结构布局合理，操作方便，很符合人体工程学原理，不会出现手滑误按的情况出现。
具体地工作原理如下：
高频电流通过电线与控制电路板122连接，控制电路板122上有电切电凝开关，控制电路板122通过导线与金属导电片017连接，导电片017与第二连接件119也就是金属接头固定，第二连接件119与刀管112固定，刀管112与切割刀头111连接，控制按钮121上设有第一触发部125和第二触发部126也就是两个按钮，分别控制控制电路板122上的两个开关，控制按钮121上部为电切按钮，下部为电凝按钮，通过控制按钮121按下上部或下部按钮，分别对电切和电凝功能进行开关控制，从而实现电切电凝功能。当然需要说明的是，上部为电切按钮，下部为电凝按钮，这些并不是限制性的规定，上下位置可根据需要进行选择。
阀芯24插设于阀座23腔体内，阀座23与冲洗管道2连接，冲洗管道21外接生理盐水管，按下阀芯24外部的按压部241，阀芯24运动，阀芯24内部有管路，阀芯24内部管路与冲洗管道21管路连通从而使得阀座23通过阀芯24与冲洗管道2连通，并且与锁紧开关25接触，锁紧开关25锁住阀芯24且保持位置固定，从而实现持续冲水功能，再次按压阀芯24外部的按压部241，锁紧开关25松开并在复位的第二弹簧245作用下弹出阀芯24，阀芯24内部管路与冲洗管道21管路断开从而使得阀座23通过阀芯24与冲洗管道2断开，冲水停止。
弹性导通件322在阀座23的用于连接负压吸引管的吸引管道31内部，将第二吸引管道312与负压吸引管相连，并按下扳机323，推杆327朝向第一吸引管道311移动，第四弹簧326被压缩，推杆327一端沿第二芯体3242的倾斜面滑动，使第二阀芯324朝向第二吸引管道312的方向移动，第三弹簧325被压缩， 第二密封圈328与挡圈313分离，负压吸引管与刀管112相通，实现吸引功能。当需要关闭吸引功能时，松开扳机323，第三弹簧325、第四弹簧326恢复原长，推杆327恢复原位，第二阀芯324也恢复原位，第二密封圈328与挡圈313抵接，负压吸引管与刀管112不相通，实现吸引功能关闭。
实施例二
本实施例与实施例一类似，所不同之处在于，如图13所示，本实施例中第二阀芯324包括第一芯体3241和与第一芯体3241连接的第二芯体3242；第二芯体3242的上端与推杆327相抵接，第三弹簧325的一端与第二吸引管道312内壁相抵，第三弹簧325的另一端与第二芯体3242的下端相抵；第一芯体3241位于第二芯体3242的上方，第一芯体3241的上端抵接于第一主体部分3111与第二主体部分3112之间的阶梯位处，且第一芯体3241上套接有用于密封的第二密封圈314，能够提高弹性导通件322在未被压缩的状态下与吸引管道31之间的密封性。
使用时，按下扳机323推动第二芯体3242下移，此时第一芯体3241也随之下移，第一芯体3241与第一主体部分3111与第二主体部分3112之间的阶梯位分离，使吸引管道31实现导通。
具体地：
弹性导通件322在阀座23的用于连接负压吸引管的吸引管道31内部，一端通过第二密封圈314与第一主体部分3111与第二主体部分3112之间的阶梯位处密封接触，另一端通过第三弹簧325支撑使得弹性导通件322通过第二密封圈314与吸引管道31压紧从而实现气阀阀路关闭；推杆327一端与扳机323接触，另一端与第二芯体3242接触；第二吸引管道312一端与第一吸引管道连接，另一端与外部负压吸引管连接；当按下扳机323时，推杆327往第二阀芯324方向运动，推动第二阀芯324上斜面从而使第二阀芯324向下运动，使第二密封圈314以及第一芯体3241从第一主体部分3111与第二主体部分3112之间的阶梯位处移走从而负压阀路打开，实现吸引功能；当松开扳机323时，推杆327往扳机323方向运动，第二密封圈314以及第一芯体3241重新回到第一主体部分3111与第二主体部分3112之间的阶梯位处密封接触从而负压阀路关闭，吸引功能关闭。
显然，本发明的上述实施例仅仅是为清楚地说明本发明所作的举例，而并非 是对本发明的实施方式的限定。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。凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明权利要求的保护范围之内。
