Description

激光光纤操作器 技术领域
本发明涉及的是激光手术设备领域，具体地说是激光光纤操作器。
背景技术
激光因其高效性、精准性和良好的切割止血效果，不仅可以用来切除体表皮肤和肿块等，近年来逐渐被用于腹腔镜下内脏器官的切除手术中，并且作为新技术，大有取代传统手术刀的趋势，而且，随着各种不同波长激光光纤的开发应用，未来激光医学在临床中的适用范围会越来越广。
然而，在目前腹腔镜手术临床上却没有一款专用的激光光纤操作器械，因此，一些医师开始尝试在腹腔镜手术中使用激光光纤进行手术治疗时，只能借用一些临时的操作杆来操作激光光纤，但使用起来非常不方便，另外暴露出以下诸多问题：
1.由于激光光纤的高能量，术中需要持续用水进行冷却，以减少创面焦痂形成；
2.基于上述，激光光纤在切除脏器或人体组织时也会产生大量的烟雾，使得操作视野模糊不清，需要进行及时排出；但由于腹腔镜手术建立有气腹压，如果漏气或在吸引时吸引位置不精准、不及时，在保证吸引目的同时会过吸多余气体，导致气腹压急剧不足和不稳定，影响手术操作空间和干扰手术的精确操作。
3.基于上述，为实现吸引冲洗，不得已在患者皮肤上额外开设2个切口，并且增加腹腔镜下2个操作戳卡，导致手术成本增加；另外，在临床操作时，至少需要额外增加1名助手协助术中持续注水冷却，以及使用吸引器抽吸血水和烟雾。
因此，综上可知，不仅大大降低了手术操作的舒适性和手术效率，而且增加了皮肤切口数和增加了手术耗材使用；严重制约激光手术广泛应用性。
鉴于以上问题，设计一款激光光纤操作器。

具体实施方式
以下结合具体实施例对上述方案做进一步说明。应理解这些实施例是用于说明本发明而不是限制本发明的范围。实施例中采用的实施条件可以根据具体厂家的条件做进一步调整，未注明的实施条件通常为常规实验中的条件。
在一种具体实施例中，提供了一种激光光纤操作器，具体包括：
能够引入腹腔内第一引管10、第二引管11和第三引管12；以及用于安装及固定三根引管的第一管套1，这里的第一管套1相当于一个安装座，将三根引管安装其前端，并且三个引管之间构建前端引流通道，即包括第三通道P3、第二通道P2和第一通道P1。
另外，操作器还包括安装在第一管套1后端的第二管套2和第三管套4，二者之间形成后端引流腔，即第一后腔C1和第二后腔C2，并且两腔体分别连通有相应控制阀，控制冲洗量和吸引量。
为实现冲洗和吸引功能，前端引流通道和后端引流腔为连通设置。
在操作器后端还设置有第四套管5和第五套管6，第五套管6螺接在第三管套4后端，第四套管5螺接或插接在第五套管6的后端，其中，第四套管5主要用于光纤a后端的安装或固定，保证光纤a前端能够沿引管内侧设置及光纤a的稳定设置。另外，在操作时作用操作器的手柄使用，便于手术操作；第五套管6主要用于光纤a后端连接处的密封，避免液体从第四套管5末端泄漏，其中，在第五套管6前端设置有一个密封垫14，第五套管6后端设置有一个防水冒15，二者仅为弹性橡胶材料制成，光纤a能够密封的穿过二者，可以见得密封垫14和防水冒15相对于双层密封，进而进一步提高密封效果，在此基础上，在第四套管5末端设有弹性尾冒16，对光纤a后端进行支撑，避免光纤a发生大幅度弯折而损坏。
为实现光纤a的安装和布置，本实施例中光纤a设置在操作器轴线上，并从前端向后端延伸设置，前端用于切割，后端则与激光发生器连接。
综合上述，本实施方案的具体结构和连接形式如下：
第一管套1轴心贯通设置有用于穿设光纤a的前通道1.4；光纤a穿设后通常与前通道1.4之间留有间隙，用于冲洗液通过，因此，本实施例中，由于光纤a与前通道1.4最为接近，前通道1.4主要用于释放冲洗液对切割处进行清理和冷却。
为实现冲洗液进入，在第一管套1侧壁开设有与前通道1.4连通的第一接口1.6，并且为控制冲洗液通断和冲洗流量在第一接口1.6安装有第二旋阀9，其中，第二旋阀9通常选用球阀，本实施例中，第二旋阀9能够实现相应通道常开和常闭效果。
在本实施例中，第一引管10、第二引管11和第三引管12同轴安装于第一管套1前端，并且依次从外侧向内侧排列设置；其中，第一引管10与第二引管11 之间形成第三通道P3，第二引管11与第三引管12之间形成第二通道P2，第三引管12内侧为第一通道P1，并且第一通道P1与前通道1.4连通实现冲洗液的引导至切割组织处。
作为上述实施方式的优选实施例，为便于各引管的安装稳定性和密封连接，第一管套1前端分别开设有第一环槽1.1、第一环槽1.2、第三环槽1.3，并且沿第一管套1径向依次从外侧向内侧排列设置，第一引管10、第二引管11以及第三引管12按从外侧向内的排列顺序安装在对应的环槽中，因此，通过槽能够对引管端部进行限位和固定，具体的应该与槽采用螺纹连接或紧配插接。
其中，本实施例中，第三通道P3主要用于烟雾吸引，第二通道P2主要用于冲洗液吸引。
为实现后端引流，操作器后端具体连接结构如下：
在第一管套1后端螺接第二管套2，这里螺接为实现导流，通常是密封连接。另外，为实现向外引流，同样，在第二管套2侧壁开设有第二接口2.1；第二接口2.1安装有第一旋阀8，可选用球阀，能够实现相应通道常开和常闭效果。
为构建后端引流腔，还包括一个第三管套4，它的前端设置有延伸接管4.1，延伸接管4.1主要作用能够与第二管套2形成套设结构。
具体安装，延伸接管4.1前端密封连接于第一管套1，延伸接管4.1后端螺接于第二管套2后端，这里的螺接也是密封螺接。这样延伸接管4.1与第二管套2之间形成导流的第一后腔C1，并且延伸接管4.1内侧形成第二后腔C2，二者形成非连通相互独立的腔体，形成各自引流通道便于引流控制。
作为上述实施方式的优选实施例，为实现延伸接管4.1的定位以及与第一管套1后端的密封连接，在第一管套1后端开设有第四环槽1.5，其槽底设置有弹性胶圈，安装后，延伸接管4.1插接在第四环槽1.5内并且抵压在弹性胶圈上，即 可实现端部密封。
作为本实施例的优选方案，通过上述可知，第一管套1后端螺接第二管套2，以及延伸接管4.1后端螺接于第二管套2后端，由于第一管套1均采用螺接，当在安装时，为保证第一旋阀8和第三接口4.4的安装位置同时螺纹达到密封要求，采用一个中间套3，避免选旋拧时第二管套2和延伸接管4.1同步转动，具体结构如下：
在延伸接管4.1周壁设置有锥形薄壁卡环4.11，其环壁上设置有若干开口槽；由于薄壁卡环4.11压缩开口槽变形，中间套3从卡环4.11小径端密封套设在延伸接管4.1后端，这里的密封通常是中间套3内部设置有密封圈，密封圈能够与延伸接管4.1实现运动密封连接。在中间套3设置有对接插槽3.1，其内侧设置有螺纹，并与第二管套2螺接，因此，避免了延伸接管4.1的转动，而利用中间套3转动推动延伸接管4.1移动，进而提高使用方便性。
其中，前后端引流连接方式为：第二通道P2与第二后腔C2连通，所述第三通道P3与第一后腔C1连通。
另外，根据上述可知，由于前通道1.4主要为冲洗通道，为避免冲洗液进入第二后腔C2，在前通道1.4与第二后腔C2连通处通过密封堵套13密封；在本实施例中，为使光纤a能够密封通过，通常密封堵套13采用橡胶材料制成，并且光纤a能够密封滑动的穿过密封堵套13，具体可在与光纤a配合孔内侧设有多个密封环，密封环与光纤a外壁连接，其属于现有活动密封形式，入阀杆密封，在此不再赘述。
同理，为实现第二后腔C2向外导通，在第三管套4上设置有第三接口4.4，并且第三接口4.4安装有按压阀，这个按压阀通常是指通过按压形式导通和中断的阀门，属于点动控制阀门。使用时可通过手指按压的形式控制，阀门的通断， 实现间断性吸引，提高使用方便性。
另外，第二通道P2也可以作为冲洗通道使用，使用时，冲洗液能够从第三引管12前端周壁的通孔排出，进行辅助冲洗，并且结合按压阀的控制能够实现间断性清洗，提高使用方便性。
作为优选实施方式，为实现第二通道P2吸引或冲洗功能的选择，第三接口4.4包括第一分支口4.41和第二分支口4.42，二者分别与第二后腔C2连通；为实现第二通道P2吸引或冲洗间断控制，采用两个按压阀控制，即第一按压阀4.2和第二按压阀4.3，第一按压阀4.2控制第一分支口4.41通断，第二按压阀4.3控制第二分支口4.42通断，因此，使用时在第一分支口4.41和第二分支口4.42对应接上不同冲洗泵或吸引器即可。
具体临床使用时，先将各阀门与外部设备连接，即与相应的腹压吸引器和供水泵连通；再将光纤a从操作器后端插入并延伸至操作器前端，用于组织切割。使用时通过腹腔建立的通道将第一引管10、第二引管11和第三引管12进入腹腔，并在内镜的可视引导下使光纤a切割端到达患处，并进行切割，同时将第二旋阀9打开供给冲洗液，冲洗液通过第一通道P1引入光纤a前端进行冲洗和冷却。由于切割会存在烟雾，此时可打开第一旋阀8，使第三通道P3持续产生微小负压，再保证气腹压稳定的情况下对烟雾进行吸引；另外，冲洗液需要吸引时，可通过控制按压阀使冲洗液从第二通道P2进入，并进行收集。
因此，可以看出切割、冲洗、吸液以及吸烟都在同一个操作器上布置，主刀医生单人单手就可实现上述操作。通过光纤a安装在笔状的操作器上，能够便于对光纤的拿取与控制。
本案中，第三通道P3和第二通道P2通常通道截面较小，这样在吸引时能够避免气腹压快速降低。
另外，可以见得，由于冲洗端和吸引端均设置在光纤a切割处周围，能够快速高效的实现冲洗和吸引，尤其是吸烟时，能够在烟雾非完全扩散时进行精准快速吸引，避免过吸和漏吸，保证了气腹压平稳变动，能够改善视觉效果，提高手术效率和安全性。
另外，切割、冲洗及吸引功能及为一体设置，能够减少患者腹部开口以及减少医疗工具的使用，降低患者损伤，减少医疗费用。
综合上述实施方案，手术时，为进一步提高手术视野，便于术者观察光纤a位置，将第三引管12前端凸出于第二引管11前端设置，第二引管11前端凸第一引管10前端设置。即形成操作器前端台阶形式，这样各第一引管10和第二引管11能够减对光纤a的遮挡，提高切割精准性，进一步提高手术安全性。
为进一步提高吸引和冲洗效率以及范围，在第一引管10前端周壁和第三引管12前端周壁皆开设有通孔，其中，第三引管12前端周壁的通孔延伸至第二引管11内侧。
具体使用时，由于第一引管10为主要吸烟通道，通过前端侧壁上的通孔能够使扩散的烟雾进入提高吸引效率。另外，由于第三引管12前端最为凸出，在第二通道P2进行吸引时，可通过第三引管12前端周壁的通孔进行吸引，提高吸引效率，并一定程度也能够避免较大血块进入第二通道P2内。
综合上述方案，手术操作时，为实现光纤a的伸缩控制，以适用不同位置的切割，在第四套管5出设置有控制光纤a运动的机构，具体如下：
在第四套管5一侧开设有安装口5.1，安装口5.1内安装有能够沿第四套管5轴线往复推动的按钮7，其一端置于安装口5.1外侧，另一端置于内侧，并且该端设置有夹口7.1，夹口7.1能够夹持光纤a，进而在使用时推动按钮7即可实现光纤a前端的伸缩。同理，为实现第四套管5与光纤a滑动连接，在第四套管5前 端安装有密封垫14，光纤a密封滑动插接在密封垫14内。
在此基础上，为进一步实现光纤a的定位，避免切割时发生运动，在安装口5.1内侧设置有限位板5.2，并且与安装口5.1边缘形成一个插槽；另外，在按钮7周壁设置有翼板7.2，插装于插槽内；并且在插槽内侧设置一个抵接在翼板7.2上并能够使按钮7按压回弹的弹片5.3；
另外，在安装口5.1内侧边缘开设若干个排列设置的凹槽5.4，同时，翼板7.2上开设有凸点7.3，凸点7.3能够置于凹槽5.4内实现按钮7定位。具体使用时，按压按钮7使凸点7.3与凹槽5.4脱离，实现按钮7在安装口5.1内的前后滑动，进而驱动光纤a伸缩移动；当确定光纤a切割端位置后，释放按钮7，通过弹片5.3弹力使凸点7.3与凹槽5.4配合对按钮7限位，进而实现光纤a的定位。
综合上述，为了更好的便于对光纤a的夹持，夹口7.1轮廓边缘设置有一个贯穿夹口7.1的豁口7.4，通过该豁口7.4使夹口7.1产生弹性，安装时，通过掰开豁口7.4，使光纤a顺畅穿入夹口7.1，当确定夹持位置后，释放豁口7.4使夹口7.1夹持光纤a，因此，能够提高了安装方便性。
以上述依据本发明的理想实施例为启示，通过上述的说明内容，相关工作人员完全可以在不偏离本项发明技术思想的范围内，进行多样的变更以及修改。本项发明的技术性范围并不局限于说明书上的内容，必须要根据权利要求范围来确定其技术性范围。
