Description

双极电处理装置 技术领域
本发明涉及医疗器械技术领域，特别是涉及双极电处理装置。
背景技术
软式内窥镜手术因其微创、恢复快，正日益成为当下消化道、泌尿、心肺及血管外周领域常用的手术方式。在内窥镜的术前诊断中，通常需要对疑似病灶进行取活检操作，以便进行病理分析。现有方式主要为通过具有挠性轴的活检钳对病灶组织进行抓取，而抓取过程可能破坏黏膜下层的血管而导致出血，对患者造成生理负担。另一方面，由于病理分析需要保持活检组织的生物活性，使得活检钳的钳杯内部温度不能过高或过低。
公开号为CN205107883U的中国专利公开了一种带绝缘涂层的热活检钳，其通过单极电切割的方式对目标组织进行活检，其金属钳杯与贴敷于人体的负极板形成高频电流回路，从而在杯体金属刀口与组织之间电灼细胞使之破裂形成切割，在此过程中同时凝住了刀口下方的血管。然而，单极器械的电流回路流经较大范围的人体，对于心脏起搏器或ICD(埋藏式心律转复除颤器)植入患者，电流可能通过起搏器环路，灼伤环路上的肌体组织，严重者可能灼伤心肌。
公开号为WO1994017741A1的美国专利公开了一种双极活检器械，其将两钳杯分别连接于电源正负极，从而在钳杯之间形成高频电流回路，避免了对心脏起搏器的影响。然而，由于电流集中于两钳杯之间，能量过于集中，容易导致活检组织失去生物活性；另一方面，由于活检钳外径尺寸很小，现 有设计两钳杯之间易构成短路，导致活检失效。
申请号为CN201080032498.X的中国专利还公开了一种高频处理器具，属于双极器械方案，其包括一对供电线，该供电线的第一端部以能够转动的方式与上述转动轴相连接，该供电线的第二端部与电源相连接，该一对供电线分别与上述一对钳子构件的各个上述电极部电连接。而为使内窥镜用处理装置能够自由穿行于内窥镜钳道，内窥镜用处理装置的外径受到内窥镜器械通道内径的限制，通常在2.8mm以下。两根以上操纵/供电线的布置不便于用户在近端对远端的处理部执行能够及时反馈的旋转操作，不利于手术的开展。

具体实施方式
以下将结合附图，对本发明进行更为详细的描述，需要说明的是，下参照附图对本发明进行的描述仅是示意性的，而非限制性的。各个不同实施例之间可以进行相互组合，以构成未在以下描述中示出的其他实施例。
请参阅图1，本发明的一实施例中提供了一种双极电处理装置1000，该双极电处理装置1000包括：钳头机构100，鞘管机构200，电极机构300，手柄机构400，以及安装于鞘管机构200中的双极联动结构。该钳头机构100装设在鞘管机构200的右侧端部，并可相对于鞘管机构200进行转动；鞘管机构200的左侧端部装设在电极机构300上，并且鞘管机构200与电极机构300相连通；手柄机构400装设在电极机构300的左侧，并能够相对于电极机构300转动。双极联动结构包括导电牵引绳240、绝缘连接件220和操纵件130，操纵件130包括第一导电操纵件131和第二导电操纵件132(参见图11)。
请一并参阅图2至图5，该钳头机构100包括：两个绝缘钳杯110、绝缘杯座120，具体如下：
各个绝缘钳杯110相对的侧面均形成有杯体111，该杯体111用于容纳被抓取的活检样本，各个杯体111相对设置，并且各个杯体111的形状相适配，该杯体111位于绝缘钳杯110侧面的端部位置处；绝缘钳杯110的外侧布设有导电层(图未示)，各个绝缘钳杯110的导电层可分别连接一根操纵件(130)，以便于在两个绝缘钳杯110外侧形成高频电流回路；另外，该杯体111的内侧壁始终保持为绝缘状态以及该杯体111的刃口1111也始终保持绝缘，以使被抓取至杯体111内的活检样本处于隔绝状态，从而能够避免因绝缘钳杯110外侧壁的电能过于集中而令杯体111内的活检样本丧失生物活性。另外，在绝缘钳杯110外侧所铺设的导电层可以采用电镀或喷涂等方式进行布设。
可以理解的，当两个绝缘钳杯110由张开状态转换为咬合状态的过程中，各个绝缘钳杯110上的刃口1111将对病灶组织进行切割得到活检样本；同时，在两个绝缘钳杯110处于咬合状态时，两个杯体111相互围设形成处于绝缘状态的密封腔体，活检样本被容置在密封腔体内，进而令活检样本与绝缘钳杯110发热的部位相隔绝，能够有效保证活检样本的生物活性。
可以理解的，在各个绝缘钳杯110处于咬合状态时，由于各个绝缘钳杯110外侧的导电层通过各个操纵件130分别与不同电极电路(正极电路或负极电路)进行电连接，以及各个绝缘钳杯110的外径尺寸较小的原因，容易造成短路现象，进而易导致活检失效。因而，各个杯体111的刃口1111始终保持绝缘状态的设置，能够避免处于咬合状态的各个杯体111之间存在电性接触，进而防止出现短路现象，也能够避免出现活检失效的问题。
可以理解的，如图3所示，上述杯体111的刃口1111呈齿状设置，以使两个绝缘钳杯110之间可通过呈齿状设置的刃口1111相互咬合，便于对出血 部位进行电凝操作。另外，如图4所示，杯体111的刃口1111也可设计为环形刃口，便于对待活检的样本进行切割。上述杯体111的刃口1111的形状并不局限于图3或图4所示的形状，本领域的技术人员也可将刃口1111设计为其他类型的形状，以满足对出血部位进行电凝或对待活检样本进行电切割等操作。
其中，各个绝缘钳杯110远离杯体111的一端均铰接在绝缘杯座120的同一端部，并且各个绝缘钳杯110与绝缘杯座120相铰接的位置相平行间隔设置，即；各个绝缘钳杯110与绝缘杯座120相铰接的端部之间相间隔交叉分布，以避免因各个绝缘钳杯110外侧的导电层相交叉接触而引发短路现象。
其中，各个操纵件130一一对应铰接在各个绝缘钳杯110远离杯体111的端部，并且其中一个操纵件130的外侧布设有绝缘层(图未示)。可以理解的是，布设有绝缘层的操纵件130与绝缘钳杯110相铰接的位置未布设绝缘层，即：布设有绝缘层的操纵件130始终与绝缘钳杯110的导电层之间进行电性连接。
可以理解的，基于各个操纵件130的推拉过程，各个绝缘钳杯110能够进行张开操作或咬合操作，即工作人员可借助其他结构对各个操纵件130进行操作，以使各个绝缘钳杯110由张开状态调整为咬合状态(或者由咬合状态调整为张开状态)。
可以理解的，绝缘钳杯110及绝缘杯座120可以是由陶瓷、特氟龙、PEEK等不同的绝缘材料制备而成。该绝缘杯座120优选为PEEK材料进行制备。
请一并参阅图6至图9，在绝缘钳杯110上开设有第一通孔112，该第一通孔112位于绝缘钳杯110的中部，其杯体111位于绝缘钳杯110远离绝缘杯座120的端部；绝缘杯座120的端部径向开设有第二通孔121，第一通孔 112能够正对于第二通孔121，进而销轴140可顺次穿过第二通孔121及第一通孔112，即：销轴140由第二通孔121的一侧穿入，并穿过各个绝缘钳杯110上的第一通孔112，最终销轴140将穿入至第二通孔121的另一侧，从而令各个绝缘钳杯110铰接在绝缘杯座120的端部位置处。
另外，绝缘杯座120的端部相对两侧开设有多个第一开口122，各个第一开口122相互平行间隔设置，并且各个第一开口122均与第二通孔121相连通，各个绝缘钳杯110一一对应穿设于各个第一开口122内。
可以理解的，两个绝缘钳杯110远离杯体111的端部可分别从绝缘杯座120相对的两侧穿入至相应的第一开口122内，以使各个绝缘钳杯110上的第一通孔112正对于第二通孔121，便于销轴140穿过第二通孔121及各个第一通孔112，能够令各个绝缘钳杯110相互间隔交叉分布，也能够使各个绝缘钳杯110铰接在绝缘杯座120的端部位置处，此时，各个绝缘钳杯110远离杯体111的端部分别位于绝缘杯座120相对的两侧。

其中，绝缘杯座120轴向开设有第四通孔123，该第四通孔123开设于绝缘杯座120远离绝缘钳杯110的一端，即第四通孔123与第二通孔121分别位于绝缘杯座120相对的两端部；另外，第四通孔123与各个第一开口122均相连通，各个操纵件130能够穿入第四通孔123内并分别经不同的第一开口122穿出，进而令各个操纵件130可与各个绝缘钳杯110远离杯体111的端部进行电连接。
请一并参阅图10及图11，该鞘管机构200的右侧端部与钳头机构100的绝缘杯座120相连通，第一导电操纵件131的周向外侧面布设有绝缘层(图未示)；第一导电操纵件131及第二导电操纵件132均穿过绝缘杯座120上的第四通孔123并穿入至鞘管机构200内，并且第一导电操纵件131与第二导电操纵件132之间相互间隔。

可以理解的，当推拉导电牵引绳240时，导电牵引绳240带动第一导电操纵件131移动，同时，绝缘连接件220及第二导电操纵件132也基于第一导电操纵件131的移动而移动，即：该鞘管机构200仅需要通过一根导电牵引绳240即可实现对第一导电操纵件131及第二导电操纵件132的推拉操作。
其中，在绝缘连接件220的外侧沿轴向开设有第一凹槽221，第二导电操纵件132远离绝缘钳杯110的端部固定嵌设在该第一凹槽221内，以使该第二导电操纵件132与绝缘连接件220呈一体式结构，进而该第二导电操纵件132能够与第一导电操纵件131同时移动。

其中，第一限位管250的外侧套设有第一绝缘管251，并且该第一绝缘管251与绝缘连接件220之间无缝连接，以使第一限位管250处于绝缘状态，避免因第一限位管250与第二导电操纵件132之间电性接触而造成短路。
可以理解的，该第一绝缘管251优选为具备绝缘性能的花纹管，同时，第一导电操纵件131位于第一绝缘管251靠近绝缘杯座120一侧的部分管段的外侧也套设有花纹管，能够有效保证第一导电操纵件131与第二导电操纵件132之间的绝缘稳定性，避免在导电部件210内出现短路现象。
其中，在导电牵引绳240的外侧套设有第二绝缘管241，该第二绝缘管241朝向绝缘连接件220的端部沿导电牵引绳240的外侧面延伸至绝缘连接件220并与该绝缘连接件220相连接，同时该第二绝缘管241位于绝缘连接件220朝向导电牵引绳240一侧的第一绝缘管251的外侧。另外，在该第二绝缘管241的外侧还套设有润滑管242，能够降低导电牵引绳240推拉过程中存在的阻力。

另外，推拉杆440穿设在导电套管370的内侧，并位于导电牵引绳240的外侧面。可以理解的，流经导电弹片330的电流依次经导电套管370、推 拉杆440流动至导电牵引绳240内。
另外，第四绝缘管380面向手柄410的一端沿推拉杆440的外侧面延伸至绝缘盖体360内，以使推拉杆440与导电部件210之间相互绝缘；同时，第二绝缘管241远离手柄410的一端与绝缘连接件220相连接，另一端与推拉杆440相连接。基于此，位于第二绝缘管241及推拉杆440内的导电牵引绳240处于绝缘状态，即导电牵引绳240与导电部件210之间不存在电性接触。
其中，滑动指环420处固定装设有第四固定管450，该第四固定管450位于手柄410内部，推拉杆440远离钳头机构100的一端固定穿设在第四固定管450上，以使推拉杆440可在滑动指环420的带动下移动。
上述实施例中所提供的双极电处理装置1000，其钳头机构100的张开或咬合过程，如图10所示，可详述为：
当用户利用食指与中指拉动滑动指环420朝向右侧移动时，滑动指环420带动推拉杆440朝向右侧移动，导电牵引绳240也朝向右侧移动，进而导电牵引绳240拉动第一导电操纵件131及第二导电操纵件132朝向右侧移动，从而令钳头机构100中的两个绝缘钳杯110处于张开状态，如图2所示；
当用户利用食指与中指拉动滑动指环420朝向左侧移动，滑动指环420带动推拉杆440朝向左侧移动，导电牵引绳240也朝向左侧移动，进而导电牵引绳240拉动第一导电操纵件131及第二导电操纵件132朝向左侧移动，从而令钳头机构100中的两个绝缘钳杯110处于咬合状态，如图3所示。
另外，当用户顺时针或逆时针转动手柄410时，推拉杆440也将顺时针或逆时针转动，进而带动导电牵引绳240、第一导电操纵件131、第二导电操纵件132及绝缘钳杯110进行顺时针或逆时针转动。
上述实施例中所提供的双极电处理装置1000的电流流动过程可详述为：外部电源设备的正极所输入的电流将顺次流经电连接器320、导电弹片330、导电套管370、推拉杆440、导电牵引绳240、第一导电操纵件131、与第一导电操纵件131相连接的绝缘钳杯110的导电层；然后，电流经与第二导电操纵件132电连接的导电层流动至第二导电操纵件132、导电部件210、导电丝340及导电体350，并最终经与导电体350相连接的导线回流至外部电源设备的负极。
上述实施例中所提供的双极电处理装置1000，具有如下优点：
1、钳头机构100是通过设置由绝缘材料制成的两个绝缘钳杯110并在绝缘钳杯110的外侧布设导电层，同时令杯体111的内侧壁保持绝缘状态，以便于能够在绝缘钳杯110的外侧构成高频电流回路；同时也能够令杯体111内容置的活检样本处于绝缘状态，以避免杯体111内的活检样本失活。
2、导电部件210内的一根导电牵引绳240与第一导电操纵件131相连接，第二导电操纵件132固定装设在绝缘连接件220上，并且绝缘连接件220固定套设在第一导电操纵件131上，进而能够仅通过拉动或转动导电牵引绳240即可实现对钳头机构100进行操纵的效果，能够避免因导电部件210内操纵线或导电线过多而带来的操作不便；同时，在第一导电操纵件131的外侧设置绝缘层，能够避免出现短路现象。
3、电极机构300是通过电连接器320与外部的电源设备的正极相连接，进而令外部电源设备所输出的电流依次流经电连接器320、导电弹片330、鞘管机构200及钳头机构100，然后电流经钳头机构100顺次回流至鞘管机构200、导电丝340、导电体350，并最终经与导电体350相连接的导线流至外部电源设备的负极，从而构成完整的高频电流回路，其流经的人体的面积较 小，能够避免对心脏起搏器或ICD植入患者的肌体造成灼伤，具有较好的安全性。
上述实施方式仅为本发明的优选实施方式，不能以此来限定本发明保护的范围，本领域的技术人员在本发明的基础上所做的任何非实质性的变化及替换均属于本发明所要求保护的范围。
